rsync delays

2026-06-04T17:31:53Z

I’ve been deploying my site old school for most of this year, rsync to a volume mounted to nginx. I ran into an issue today where I updated my site and all of the pages updated first, followed by upload. The issue this created was that the new cache busted css files were not up yet and the site had no styles for a brief period during upload.

I found that delaying updates and delaying deletes until the new content exists first solves this problem pretty well. Theres still possiblility of jank while uploading to a live directory and not doing some sort of hot swap, but I’m good with this low budget option for now.

sync:
	rsync -rlt --delete --omit-dir-times \
	--info=progress2 \
	--delay-updates \
	--delete-delay \
	./output/ \
	server:/mnt/mysite

forgejo push to create

2026-05-06T21:58:55Z

I just learned that forgejo has a push to create repo feature and it is a gamechanger. Upon first try it didn’t work, with just a couple of environment variables I was up and running with push to create.

notify.wayl.one on  main is 📦 v0.1.62  v3.14.4  NO PYTHON VENV SET  USING SYSTEM NVIM

nless

2026-05-06T20:45:01Z

nless is a seriously sick tui for exploring streaming data. It makes it seriously simple to pivot (U), drill in (Enter), sort (s). It leave breadcrumbs as you go and you can press q to back out.

Play with your kubernetes events. Ya, my homelab is far from perfect, dont judge.

image compare in markata go

2026-05-01T07:40:44Z

markata-go now has web awesome integration for image compare. It renders a nice web component with a slider to compare two images.

It’s done with a class wrapper around the image components.

testing copilot model flag

2026-04-29T11:05:39Z

Today I found a way to test model syntax, cause the clankers always get the exact model name that copilot wants wrong.

copilot --model claude-sonnet-4.5 -p "Reply with OK" --allow-all --no-ask-user -s
copilot --model gpt-5.4 -p "Reply with OK" --allow-all --no-ask-user -s

stow local ignore

2026-04-18T10:36:00Z

Stow comes with a local and global ignore list that you can use to ignore certain files or directories.

If you put Perl regular expressions, one per line, in a .stow-local-ignore file within any top level package directory, in which case any file or directory within that package matching any of these regular expressions will be ignored. In the absence of this package-specific ignore list, Stow will instead use the contents of ~/.stow-global-ignore, if it exists. If neither the package-local or global ignore list exist, Stow will use its own built-in default ignore list, which serves as a useful example of the format of these ignore list files:

move zmk keyboard to new bluetooth adapter

2026-03-23T17:59:59Z

I’ve been having issue with my keyboard disconnecting to my main desktop for awhile. Today I got a cheap bluetooh dongle in and am giving it a run this week to see how things go. The first step was to move it to the new adapter. I’ve never had multiple adapters installed so this was a new to me process.

I was able to do it all with the same keyboard, It did require some juggling between usb and bluetooth modes pluging and unplugging, two keyboards would be simpler to reason about.

I can’t be bothered to change my brain to think about this machine on a different zmk profile it is of absolute importance for it to remain on the same profile, otherwise this would be a simple bind to another empty profile.

Why not use a cable on desktop?

I dont mind cable, and have used one on this setup for years, but I have actually been picking up and moving this keyboard and using it with different devices.

I’ve got a big battery and performace cranked up, unless my machine is under load I do not notice any key lag.

I did it with bluetoothctl, I’m sure it could have been done with a gui like blueberry or blueman.

bluetoothctl
# list adapters
list
select <old-adapter>
devices
# fin the MAC address of the device 42BLOCK
remove <42BLOCK_MAC>

Now I plugged into usb. And importantly cleared out the zmk profile. If you do not clear the profile your board does not go into pairing mode.

bluetoothctl
# switch adapters
select <new-adapter>
power on
agent on
default-agent
scan on
Put 42Block in pairing mode, then:
pair <42BLOCK_MAC>
trust <42BLOCK_MAC>

At this pint I saw this show up in the logs, I think there was some masking issues or something in zmk, output kept going out usb no matter what so I disconnected the keyboard and typed the passkey in, and it worked.

[agent] Passkey: 540044

Boom, it just started working right away.

bluetoothctl
connect <42BLOCK_MAC>
info <42BLOCK_MAC>
scan off
exit

dot dockerenv

2026-03-18T10:07:16Z

Today I learned that docker creates an empty /.dockerenv file to indicate that you are running in a docker container. Other runtimes like podman commonly use /run/.containerenv. kubernetes uses neither of these, the most common way to detect if you are running in kubernetes is to check for the presence of the KUBERNETES_SERVICE_HOST environment variable. There will also be a directory at /var/run/secrets/kubernetes.io/serviceaccount that contains the service account credentials if you are running in kubernetes.

gh do I have a pr

2026-03-02T08:47:44Z

In the age of agents sometimes work gets done on so many different worktrees and branches its hard to tell if there is already a PR or any of them or not, the great gh cli has us covered.

double gutter

2026-02-14T09:12:42Z

I keep forgetting about the double gutter problem with nested containers. When you put padding on a parent and the child also has padding, you get twice the spacing you wanted.

The Problem #

.container {
  padding: 2rem;
}

.child {
  padding: 2rem;
}

Now your content is 4rem from the edge. Not what I meant at all.

The Fix #

Either remove padding from the parent or use box-sizing: border-box and plan for it. I usually just drop the parent padding when I realize what I have done.

diff kubernetes manifest with cluster

2026-02-05T09:37:39Z

Like a dufus this morning I did a hard reset on a git repo for getting I was working on a manifest for. You see I generally use argo, but occasionally I have no idea what I am doing or want yet and I start raw doggin it, fully aware that I’m going to just nuke this namespace before getting it into a proper argocd.

I was overjoyed when I found out that you can diff your manifests with live production using the kubectl diff command. It uses standard diff so you can bring all your fancy diff viewers you like.

# regular manifest
kubectl diff -f k8s/shots -n shot
# kustomize
kubectl diff -k k8s -n go-waylonwalker-com
# using a fancy diff viewer
kubectl diff -f k8s/shots -n shot | delta
# using an even fancier diff viewer
# pinkies out for this one
kubectl diff -f k8s/shots -n shot | delta --diff-so-fancy

Now I can get those changes back that I thought I lost, and apply updates with confidence knowing what is about to change.

format markdown with mdformat

opencode variants

2026-01-13T08:53:36Z

Opencode is changing on the daily right now, today I noticed the word low pop up in Orange text in my opencode window. Looking into this they are exposing variants to the user. This allows you to change between fast or slow and thinking, the later taking more time to prepare before doing an action.

Swapping Variants in opencode

It looks like this toggle may have been here for awhile and I’m just now discovering it. Potentially because its a new feature of the free Zen provider.

Variants Many models support multiple variants with different configurations. OpenCode ships with built-in default variants for popular providers.

Built-in variants OpenCode ships with default variants for many providers:

Anthropic:

high - High thinking budget (default) max - Maximum thinking budget OpenAI:

Varies by model but roughly:

none - No reasoning minimal - Minimal reasoning effort low - Low reasoning effort medium - Medium reasoning effort high - High reasoning effort xhigh - Extra high reasoning effort Google:

low - Lower effort/token budget high - Higher effort/token budget

tpope vim-speeddating

2026-01-04T16:59:33Z

Today I discovered vim-speeddating by tpope. I’m sure I’ve seen years ago but it did not click for my workflow until today. I often go through pictures from my phone for the past few days and make Posts tagged: shots posts, but I want to date them to about when the image was taken most of the time. This allows me to quickly bump days up and down using c-a and c-x even around the new year.

light mode screen recording css

2026-01-02T10:29:10Z

Yesterday I wrote about a way to do light mode screen recording to convert to light mode from dark mode with ffmpeg. I was wondering if it could be done entirely on the front end for web applications. Turns out you can. I’m sure there are limited wikis and site builders that don’t allow adding style like this, but it works if you can.

2026-01-01T10:14:17Z

I saw this tip from Cassidoo and had to try it out for myself. I kicked on a screen recording right from where my terminal was, converted it, and it actually looks pretty good.

ffmpeg \
   -i screenrecording-2026-01-01_10-10-49.mp4 \
   -vf "negate,hue=h=180,eq=contrast=1.2:saturation=1.1" \

There are a few unsettling things about it, but overall I feel like it was a success.

YouTube Gemini is Actually Useful

2025-12-22T10:09:55Z

I’ve found Gemini to be very useful lately, especially for finding information within long form content.

When writing thought-896, I wanted to use a direct quote from Jeff Dickey, Gemini popped it out very quickly.

give me a quote from jeff just before the timestamp I'm at the interviewer
asked what makes a good cli and he started talking about stdout/stderr

In another case, my wife and I are huge Good Eats fans. Alton Brown taught us how to cook during college and on. We watched every single good eats episode nearly 10 years after they aired. He is back with some updates to those those shows on his Youtube. Gemini gives very good detailed responses with timestamps.

Alton Brown had a recent YouTube video for cooking turkey. Can you get the
instructions from the video?

numbered posts in obsidian

2025-12-13T22:28:28Z

I’ve been using this one for awhile now, I have a post type that I only edit from my phone, but I have all the post numbered. I set up a template in obsidian for using templater, the template goes right in the static site repo, I point templater to the templates directory and this has been working pretty seamlessly for awhile.

---
date: <% tp.date.now("YYYY-MM-DD HH:mm:ss") %>
templateKey: myposttype
published: true
tags:
- myposttype
<%*
const folder = "pages/myposttype";

// get all files in the vault, keep only those inside the folder
const files = app.vault.getFiles().filter(f => f.path.startsWith(folder + "/"));

// extract numeric suffixes from filenames like myposttype-123.md
const nums = files.map(f => {
  const m = f.basename.match(/^myposttype-(\d+)$/);
  return m ? parseInt(m[1], 10) : null;
}).filter(n => n !== null);

// next number (start at 1 if none exist)
const next = (nums.length ? Math.max(...nums) : 0) + 1;

// include the .md extension when moving
const newPath = `${folder}/myposttype-${next}`;
await tp.file.move(newPath);
%>

git name status

2025-12-12T07:53:57Z

--name-status is a great way to see what files have changed in a git diff alongside the status code. I recently used this in a script to create a report of new and modified files during a build.

git diff --name-status
git diff --name-status origin/main
git diff --name-status --staged
git diff --name-status 'HEAD@{3 days ago}'

minecraft server memory

2025-12-10T08:46:36Z

I learned to today that setting MEMORY on your minecraft server causes the JVM to egregiously allocate all of that memory. Not setting it causes slow downs and potential crashes, but setting INIT_MEMORY and MAX_MEMORY gives us the best of both worlds. It is allowed to use more, but does not gobble it all up on startup.

In this economy we need to save all the memory we can!

Here is a non-working snippet for a minecraft server deployment in kubernetes.

      containers:
        - name: dungeon
          image: itzg/minecraft-server
          env:
            - name: EULA
              value: "true"
            - name: INIT_MEMORY
              value: "512M"
            - name: MAX_MEMORY
              value: "3G"

and in docker compose

  dungeon:
    image: itzg/minecraft-server
    environment:
      EULA: "true"
      INIT_MEMORY: "512M"
      MAX_MEMORY: "3G"

web snow fall

2025-12-09T10:21:17Z

I found snow-fall component from zachleat, and its beautiful… to me. I like the way it looks, its simple and whimsical.

Install #

There is an npm package @zachleat/snow-fall if that’s your thing. I like vendoring in small things like this.

curl -o static/snow-fall.js https://raw.githubusercontent.com/zachleat/snow-fall/refs/heads/main/snow-fall.js

I generally save it in my justfile so that I remember how I got it and how to update…. yaya I could use npm, but I don’t for no build sites.

get-snowfall:
    curl -o static/snow-fall.js https://raw.githubusercontent.com/zachleat/snow-fall/refs/heads/main/snow-fall.js

Usage #

Now add the component to your page.

<!-- This belongs somewhere inside <head> -->
<script type="module" src="snow-fall.js"></script> <!-- Adjust the src to your path -->

<!-- This belongs somewhere inside <body> -->
<!-- Anything before will be below the snow. -->
<snow-fall></snow-fall>
<!-- Anything after will show above the snow. -->

check your kubeconfig expire time

2025-12-08T20:59:27Z

Today I learned an important lesson that you should periodically check on your kubeconfigs expiration date. It’s easy to do. You can ask for the client-certificate-data from your kubeconfig, decode it, and use openssl to get the expiration date.

kubectl config view --raw -o jsonpath='{.users[0].user.client-certificate-data}' \
  | base64 -d 2>/dev/null \
  | openssl x509 -noout -dates

Note

This will only work for the first user, if you have more than one user or context defined in your kubeconfig you will need to adjust.

gh auth switch

2025-12-07T10:55:55Z

When using two GitHub accounts the gh cli gives very easy gh auth switch workflow from the cli.

from the docs

gh auth switch –help Switch the active account for a GitHub host.

This command changes the authentication configuration that will be used when running commands targeting the specified GitHub host.

If the specified host has two accounts, the active account will be switched automatically. If there are more than two accounts, disambiguation will be required either through the --user flag or an interactive prompt.

# list accounts
gh auth status
# switch accounds (interactive if more than 2, i've never seen this personally)
gh auth switch

setup bambu-studio in distrobox

2025-12-06T21:17:39Z

gpus are awesome and I need one for Bambu Studio to be usable in a distrobox. Adding the --nvidia flag to distrobox create bind mounts the nvidia /dev/ devices and sets up the necessary environment variables. Once we are in there are a couple of packages to install to make it work.

distrobox create --name bambu-studio --image archlinux:latest --nvidia
distrobox enter bambu-studio
sudo pacman -S nvidia-utils lib32-nvidia-utils vulkan-icd-loader

k3s system-upgrade minor by minor

2025-12-05T09:25:39Z

The k3s system-upgrade controller is a fantastic tool for upgrading k3s automatically. It has done a fantastic job for me every time I’ve used it. Today I ran it on a cluster that needed to upgrade several minors and I learned that the controller does not pick up on changes to the channel url if you change from minor to minor.

The solution I came up with was to name the plan with the version it supports. Then on each patch upgrade, change both the plan name and the channel. I use gitops with argocd, it automcatically cleaned up old plans, created new plans, and the system-upgrade-controller picked up the plan and started applying immediately.

# Server plan
apiVersion: upgrade.cattle.io/v1
kind: Plan
metadata:
  name: server-plan-v1.33 # <- This is important if you want to change the channel name
  namespace: system-upgrade
spec:
  concurrency: 1
  cordon: true
  nodeSelector:
    matchExpressions:
    - key: node-role.kubernetes.io/control-plane
      operator: In
      values:
      - "true"
  serviceAccountName: system-upgrade
  upgrade:
    image: rancher/k3s-upgrade
  channel: https://update.k3s.io/v1-release/channels/v1.33
---
# Agent plan
apiVersion: upgrade.cattle.io/v1
kind: Plan
metadata:
  name: agent-plan-v1.33 # <- This is important if you want to change the channel name
  namespace: system-upgrade
spec:
  concurrency: 1
  cordon: true
  nodeSelector:
    matchExpressions:
    - key: node-role.kubernetes.io/control-plane
      operator: DoesNotExist
  prepare:
    args:
    - prepare
    - server-plan
    image: rancher/k3s-upgrade
  serviceAccountName: system-upgrade
  upgrade:
    image: rancher/k3s-upgrade
  channel: https://update.k3s.io/v1-release/channels/v1.33

I’d love to see a better way if you have a way to upgrade through minors, or manually control the minor of your cluster let me know.

COLUMNS env var

2025-11-26T13:24:38Z

setting COLUMNS env var to a number greater than 0 will make the terminal resize to that number of columns.

COLUMNS=80 uvx --from rich-cli rich myscript.py

Note

Not all programs respct the COLUMNS env var, but rich does, and a lot of stuff I’m building uses rich.

I discovered this when I was trying to make a low effort readme generated from the code, but did not depend on the size of terminal it was ran on.

tea login flag

2025-11-23T21:09:36Z

The tea command for gitea (used by forgejo) has a flag for login. With gitea you can have multiple accounts logged in. When you try to run a command such as repo create it will prompt you which login to use, but I learned that you can bake it in to all of them with --login <login-name>

❯ tea repo create --name deleteme --description 'for example'
┃ NOTE: no gitea login detected, whether falling back to login 'git.waylonwalker.com'?

tea repo create --name deleteme --description 'for example' --login git.wayl.one

side effect of just stars

2025-11-11T21:33:33Z

I found an interesting side effect of manually running my script to generate [[ stars ]] posts is that you get notified when one gets renamed. Today I noticed that Ned Batchelder created a coveragepy org.

pydantic settings alias choices

2025-11-11T21:23:58Z

Today I learned how to use AliasChoices with pydantic settings to setup common aliases for the same field. I’m bad about remembering these things, and hate looking up the docs. I like things to be intuitive and just do the thing I want it to do. Especially when they get configured through something like yaml and do not have a direct lsp look up right from my editor. I figured out how to support what might be common aliases for a storage directory. These can be set up as environment variables and used by config.

from pathlib import Path

from pydantic import Field
from pydantic import AliasChoices
from pydantic_settings import BaseSettings

class Settings(BaseSettings):
    storage_dir: Path | None = Field(
        default=None,
        validation_alias=AliasChoices(
            "STORAGE_DIR", "STORAGE_DIRECTORY", "STORAGE_PATH", "STORAGE_PATHNAME",
            "DROPPER_STORAGE_DIR", "DROPPER_STORAGE_DIRECTORY", "DROPPER_STORAGE_PATH", "DROPPER_STORAGE_PATHNAME",
        ),
        description="Directory for stored files",
    )

uv s3 sync with dotenv

2025-10-26T10:16:41Z

I often want to run an s3 sync in an isolated environment, I don’t want to set any environment variables, I don’t want anything secret in my history, and I don’t want to change my dotenv into something that exports variables, I just want s3 sync to work. dotenv run is the tool that I’ve been using for this, and this uv one liner lets it run fully isolated from the project.

one liner #

uv tool run --from 'python-dotenv[cli]' dotenv run -- uv tool run --from awscli aws s3 sync s3://bucket data

multi-line #

same thing formatted for readability

uv tool run \
  --from 'python-dotenv[cli]' \
  dotenv run -- \
uv tool run \
  --from awscli \
  aws s3 sync s3://dropper data

There are probably 10 ways to skin this cat, but this is what I did, if you have a better way let me know, I’ll link you below.

starlette head request

2025-10-22T09:11:31Z

FastAPI.">Starlette has a head request that works right along side your get requests. This morning I fiddled around with custom routes for GET and HEAD, but had to manually set some things about the file, and was still missing e-tag in the end. Turns out as a developer you can just add a head route to your get routes and starlette will strip the content for you, while preserving all of those good headers that fastapi FileResponse created automatically for you.

from fastapi import APIRouter
from fastapi.response import FileResponse
from fastapi import Request
from pathlib import Path

router = APIRouter()

@router.get("/file/{filename}")
@router.head("/file/{filename}")
async def get_file(filename: str, request: Request,):
    headers = {
      "Cache-Control": "no-cache, no-store, must-revalidate",
    }
    from pathlib import Path
    filename = Path(f"data/{filename}")
    if not filename.exists():
        raise HTTPException(status_code=404, detail="File not found")
    return FileResponse(filename, headers=headers)

Here is an example of the response with curl.

❯ curl -I -L "http://localhost:8100/api/file/e5523925-1565-454c-bab3-c70c4deabc83.webp?width=250"

Don't copy your gitignore to stignore

2025-10-21T18:43:00Z

Today I learned that while .stignore and .gitignore look very similar they are not. My obsidian directory had been locked up for a few weeks and I had no idea why until I logged into the web ui and saw errors. The errors were some confusing regex validator not matching. I don’t know what the exact error was, but I went in and only ignored the files I cared about instead of the entire gitignore. Primarily I was getting conflicts in my .git directory.

vanilla html hover text

2025-09-16T11:39:41Z

I needed to display some hover text in a web app that I am using tailwind and jinja on. It has no js, and no build other than the tailwind. I want this to remain simple. Turns out that you can use a span with a title attribute to get hover text in HTML.

tar over ssh

2025-09-13T10:50:42Z

Today I learned how to use tar over ssh to save hours in file transfers. I keep all of my projects in ~/git (very creative I know, I’ve done it for years and haven’t changed). I just swapped out my main desktop from bazzite to hyprland, and wanted to get all of my projects back. Before killing my bazzite install I moved everything over (16GB of many small files), it took over 14 hours, maybe longer. I had started in the morning and just let it churn.

This was not going to happen for re-seeding all of my projects on my new system, I knew there had to be a better way, I looked at rsync, but for seeding I ran into this tar over ssh technique and it only took me 6m51s to pull all of my projects off of my remote server.

ssh user@192.168.1.100 'tar -C /tank/git -cpf - .' \
  | tar -C "$HOME/git" -xpf -

uv script management

2025-09-07T20:22:56Z

I’ve been leaning on lazy-self-installing-python-scripts more and more, but I did not realize how much tooling that uv gives you to help manage your scripts.

uv init --script up
uv add --script up typer rich
uv remove --script up rich
sed -i '1i #!/usr/bin/env -S uv run --script' up
chmod +x up
./up

The result is a script that looks like this, its executable as what looks like regular command in your shell.

#!/usr/bin/env -S uv run --script
# /// script
# requires-python = ">=3.13"
# dependencies = [
#     "typer",
# ]
# ///


def main() -> None:
    print("Hello from up!")


if __name__ == "__main__":
    main()

nvim delete current file

2025-09-02T13:23:21Z

This one is one that I’ve been using quite often, I did’t have a hotkey for it, I just used the rm shell command.

!!rm %<TAB><CR>

When you type !! from normal mode it will automatically put you in command mode with .! pre-filled, then you just type rm and <TAB> to auto-complete the current file name, and <CR> to execute the command.

:.!rm %<TAB><CR>

Making it better #

The one quirk that I don’t like about this is that the buffer remains open after deleting, and sometimes I forget to close it and end up re-creating it by mistake when running :wall or :xall.

Create a DeleteFile command with vim command.

:command! DeleteFile execute "!rm %" | bdelete!

Create a DeleteFile command with lua.

vim.api.nvim_create_user_command(
  'DeleteFile',
  function()
    -- Delete the current file from disk
    vim.cmd('!rm %')
    -- Close the buffer without saving
    vim.cmd('bdelete!')
  end,
  {}
)

vim noa

2025-08-29T08:32:44Z

Vim :noa is a command that runs what you call without autocommands on. This is typically used when you have some BufWritePre commands for formatting, most auto formatters are implemented this way in vim. It can be super useful if you have something like a yaml/json file that you have crafted perfectly how you want it, maybe it has some source code for a small script or sql embeded and your formatter wants to turn it into one line. You could get a better formatter, but for these one off cases that aren’t a big bother to me I run :noa w.

:noa w

modd

2025-08-25T10:48:01Z

Today I gave modd a try, and it seems like a good file watcher executor. I tried using libnotify to send desktop notifications, but all I got was modd, I might not have notifications setup right on the awesomewm machine.

config goes in modd.conf

**/*.py {
  # check formatting via ruff
  prep: ruff format --check .

  # check docstring formatting
  prep: pydocstyle .
  #
  # # check type hints via ty
  prep: ty check .
  #
  # # run linter via ruff
  prep: ruff check .
}

I installed it using installer from jpillora, pulling pre-built binaries right out of the github repo.

curl https://i.jpillora.com/cortesi/modd | bash

Then you can install it, and on file change it will run the commands you configured.

modd

bash timestamp

2025-08-22T15:35:36Z

Today I needed to make a backup of some config. I wanted to add a timestamp so that I knew when the backup was made. This would make unique backups easy, and I could tell when they were made.

cp configfile configfile.backup.$(date %s)

If you want to decrypt the timestamp into something more human readable. You can list backup files, strip out the timestamp, and then convert it to a human readable date.

/bin/ls | grep backup | sed 's/configfile.backup.//' | xargs -I {} date -d @{}

or just throw it to the date command by hand.

date -d @1755895402

qr codes in python

2025-08-05T08:32:12Z

I have a couple of use cases for simple qr codes in python coming up. One is for blog posts, the other is for auth into a new server application logged to a terminal. I tried the qrcode library and it does not look as nice to me and I found pyqrcode to be quite nice.

import pyqrcode
url = pyqrcode.create('https://waylonwalker.com/qr-codes-in-python')
url.svg('qr-codes-in-python.svg', scale=8)
print(url.terminal(quiet_zone=1))
url.svg('qr-codes-in-python.svg', scale=12)
url.svg('qr-codes-in-python.svg', omithw=True) # width is controlled by the container

url.svg('qr-codes-in-python.svg', omithw=True, module_color='#ffd119')
url.svg('qr-codes-in-python.svg', omithw=True, module_color='#ff69b4', background='#2b034c')

result #

Here is the final svg result.

Here is what it looks like in the terminal.

Dolphin Remote Storage Previews

2025-08-02T14:58:09Z

I’ve got a few samba shares going in my homelab, and I’m struggling finding a great app to scroll through vacation photos with my wife. I want something intuitive, non intimidating, and just works. Turns out that the default file browser application for hyprland works great, but you need to enable previews for remote storage for it to work for my use case here.

fc

2025-07-18T07:52:53Z

I am a linux user through and through. Desktop, server, vms, containers, everything except my phone is linux. With this I spend a lot of time in the terminal, and have been a long time user of !! to rerun the last command, but with the ability to tack something on at the beginning or end.

TIL about fc, which opens the last command in your shell history in your $EDITOR or pass in your editor -e nvim.

man fc

Rcap of how !! works #

!! pronounces bang bang and will run the last command in your history.

ls -l

!! | wc -l
# ls -l | wc -l

sudo !!
# sudo ls -l | wc -l

!!:s/-l/-l \/tmp
# sudo ls -l /tmp | wc -l

`fc` enters the chat #

Now making complex edits in your shell can be a bit of a chore, so fc moves this work to your $EDITOR.

fc

This pops open your $EDITOR with the last command in your history.

sudo ls -l | wc -l

Shell History #

fc shows up in shell history, but !! does not, !! gets replaced by the command that it becomes.

Up Arrow #

yaya yaya, I know you can also up-arrow c-e, but what fun is that, it’s barely a flex. fc just looks big brained and like you really know what you are doing.

pygments htmlformatter

2025-07-17T19:45:19Z

I’ve been a long user of pygments, it’s been the thing that injects <spans> with funny little class names like sc and si into the code blocks of my website. I’ve even gone as far as implementing a plugin for md-it, but I had no idea how to re-style it. I long ago got a theme that looked good enough from somewhere and just used it, maybe I pulled something from their docs site and forgot. Today I learned you can list all the themes easily from the library itself, and render out new css.

from pygments.styles import get_all_styles
list(get_all_styles())
# [
#     'abap',
#     'algol_nu',
#     'algol',
#     'arduino',
#     'autumn',
#     'borland',
#     'bw',
#     'colorful',
#     'default',
#     'dracula',
#     'emacs',
#     'friendly_grayscale',
#     'friendly',
#     'fruity',
#     'github-dark',
#     'gruvbox-dark',
#     'gruvbox-light',
#     'igor',
#     'inkpot',
#     'lightbulb',
#     'lilypond',
#     'lovelace',
#     'manni',
#     'material',
#     'monokai',
#     'murphy',
#     'native',
#     'nord-darker',
#     'nord',
#     'one-dark',
#     'paraiso-dark',
#     'paraiso-light',
#     'pastie',
#     'perldoc',
#     'rainbow_dash',
#     'rrt',
#     'sas',
#     'solarized-dark',
#     'solarized-light',
#     'staroffice',
#     'stata-dark',
#     'stata-light',
#     'stata',
#     'tango',
#     'trac',
#     'vim',
#     'vs',
#     'xcode',
#     'zenburn'
# ]

from pygments.formatters import HtmlFormatter
from pygments.styles import get_style_by_name
style = get_style_by_name("monokai")
formatter = HtmlFormatter(style=style)
print(formatter.get_style_defs('.highlight'))

And now you get styles that you can add to your css and be any theme from the list above.

tmux clipboard on hyprland

2025-07-06T20:45:47Z

Smooth clipboard settings for tmux is critical for my workflow. I’m often grabbing snippets of terminal output to paste into team chats, blog posts, or llm prompts. Admittedly, I’m often doing this with the mouse, unless it’s coming from neovim, which I generally do with motions. Moving from an xorg based setup to hyprland has required me to reconfigure my tmux clipboard settings. This is what I did.

First install wl-clipboard with AUR.">paru.

paru -S wl-clipboard

Next add this to your tmux config. I’ve long had this config, but with only the xorg/xclip setup, now this checks for wl-copy, uses it, or falls back to my old xclip setup.

bind -T copy-mode-vi Enter send-keys -X copy-pipe-and-cancel "bash -c 'command -v wl-copy >/dev/null && wl-copy || xclip -i -f -selection primary | xclip -i -selection clipboard'"
set-option -s set-clipboard off
bind-key -T copy-mode-vi MouseDragEnd1Pane send-keys -X copy-pipe-and-cancel "bash -c 'command -v wl-copy >/dev/null && wl-copy || xclip -i -f -selection primary | xclip -i -selection clipboard'"

virt manager on bazzite

2025-06-27T21:09:05Z

I got virtual machine manager running on two Bazzite machines today. It was a bit tricky, more than I thought actually. I ran into all sorts of virtualisation not setup issues when I tried the flatpak. Then I found that Bazzite comes with a ujust setup-virtualization command that does all the work for me. I tried that and again virtual machine manager was here, but not working, this time it feels like flatpak issues.

In a Hail Mary attempt I got it working by using an ubuntu distrobox container to run the UI. And it worked!

from the host #

From the host we create the container to use from distrobox. This is an ubuntu machine, it can be any os of your choosing, preferably one that you are familiar with and contains virt-manager in its package repos.

distrobox create -i ubuntu
distrobox enter ubuntu

from inside the distrobox container #

Now that we are in the distrobox we are no longer in an immutable distro and we can easily install anything we want. I actually like this process. I might have shit like this that I use for a month or a few months, on a normal distro, this is fully installed on the os, raises the potential of package conflicts and lengthens the update time.

sudo apt update
sudo apt upgrade
sudo apt install virtinst virt-manager
virt-manager

Along the way #

I tried adding myself to the libvirt group, and expicitly setting the socket path. After setting up another machine I realized these steps were unnecessary.

sudo usermod -aG libvirt $USER
export LIBVIRT_DEFAULT_URI="qemu+unix:///system"
ls -l /run/libvirt/libvirt-sock
virt-install --version

Note

After fully reading through `ujust setup-virtualization` I realized that it

adds me to the libvirt group, so that’s why it is not needed.

An even Better Guide #

I later found [[ thoughts-723 ]] there is documentation for setting up virtual machine manager in distrobox in the distrobox docs. It even calls out running on an immutable distro like bazzite like it knew I was coming.

copier vcs quirks

2025-06-19T08:04:51Z

Copier has a few quirks with vcs that I just discovered by trying to test out some changes. I may have some config that I have long forgotten about somewhere deep in my dotfiles, I don’t think so, but id love to be wrong and corrected, please reach out.

What Doesn’t Work #

I tried throwing everything at this template to make it work. I tried a bunch of flags that did not work. I tried making commits to the local repo to get rid of the dirty warning. I really wanted to test new changes locally without committing and pushing untested and potentially broken changes.

uvx copier copy ../markata-blog-starter .
uvx copier copy gh:waylonwalker/markata-blog-starter@develop .
uvx copier copy ../markata-blog-starter . -wlg --trust

What Works - –vcs-ref #

Finally after trying everything to get the local copy to work, and my guess of @branch not working I found this to work. It does require me to go to the repo on my develop branch.

uvx copier copy gh:waylonwalker/markata-blog-starter --vcs-ref develop .

git">What Works - delete .git #

Really this might be my best option to make quick changes and test them locally without going through a version control system. It is not ideal, but makes it easy to quickly iterate on. I might be renaming .git, or copying to /tmp for quick iteration.

rm -rf .git
uvx copier copy ../markata-blog-starter .

Copier I love #

Copier is a great templating tool. I really love it. I use it every single day to create posts on this blog using Tmux hotkey for copier templates. This is the first time this quirk has got me and it had me puzzled for 45 minutes as I did not expect this behavior whatsoever.

using yek to serialize text files into llm friendly file

2025-06-11T11:01:34Z

I’ve been using gitingest web ui [[ thoughts-516 ]] for quite awhile to serialize git repo into llm friendly text files. This gives tools context about repos that are not in the training data so that it knows about it and how to use the code in the repo. gitingest also has a python library [[ thoughts-517 ]]

I had a use case for a project not yet on git, and found yek.

Installing yek #

Their instructions tell you to curl to bash.

curl -fsSL https://bodo.run/yek.sh | bash

I don’t like curl to bash from random sites, so I have my own self hosted version of i.jpillora.com. I like using this because it pulls from github and I trust github as a source for artifacts as good as the repo I am pulling from.

curl https://i.jpillora.com/bodo-run/yek | bash

Using yek #

yek

/tmp/yek-output/yek-output-bb01e621.txt

This will give you a link to a text file that you can add to many llm tools. This happened so fast for me that I didn’t even believe that it worked properly.

more options #

As with most clis, you can run yek --help to see the options available.

yek --help

brightnessctl adjust screen brightness

2025-06-11T08:42:36Z

Today I discovered brightnessctl to adjust the screen brightness on my AwesomeWM machine. Its a command line utility that you can use to adjust the brightness of your screen. A command line interface like this gives you the ability to bind keys with something like [[xbindkeys]] or your window manager configuration.

sudo apt install brightnessctl
# or 
paru -S brightnessctl

Now that you have it installed you can use it to adjust the brightness of your screen, this worked particularly well for my laptop screen, I don’t think this works for monitors, in my experience they are usually controlled by the built in osd.

# Increase brightness by 10%
brightnessctl set +10%
# Decrease brightness by 10%
brightnessctl set 10%-
# Set brightness to 50%
brightnessctl set 50%
# Set brightness to 100%
brightnessctl set 100%

Note

on my machine I had to use `sudo` to run the command, otherwise I got the following error:

Can't modify brightness: Permission denied

You should run this program with root privileges.
Alternatively, get write permissions for device files.

rich theme

2025-06-05T20:37:10Z

The rich console is themeable, I’ve been a long time user of rich and had no Idea. You can define your own theme keywords and use them just like you use normal rich keywords in square brackets like'[bold red]'.

from rich.console import Console
from rich.theme import Theme
custom_theme = Theme({
    "info": "dim cyan",
    "warning": "magenta",
    "danger": "bold red"
})
console = Console(theme=custom_theme)
console.print("This is information", style="info")
console.print("[warning]The pod bay doors are locked[/warning]")
console.print("Something terrible happened!", style="danger")

unset multiple environment variables

2025-06-03T11:21:11Z

You can unset multiple environment variables at once. I did not know this was a thing, its something that ended up happening organically on a call and asking someone to run unset. They had never done it before and did not know how it works, but did exactly as I said instead of what I meant. I like this handy shortcut doing it in one line rather than each one individually, I will be using this in the future. You might need this for something like running aws cli commands with localstack.

unset AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY AWS_DEFAULT_REGION

i3lock on AwesomeWM

2025-06-02T14:40:56Z

i3lock is a fantastic lockscreen for tiling window managers.

If you are using a tiling window manager within a public space you need to add a lockscreen. I have one machine that I take with me to a public space. Its secure enough that I can leave it, but not secure enough that I want to leave it unlocked. So when I need to leave it behind for the restroom I need to lock it up.

arch wiki

paru -S i3lock
# or
apt install i3lock

Now that you have i3lock installed lets lock that screen.

# lock it with a pure white flashbang
i3lock

# lock it with a black background
i3lock -c 000000

# lock it with a custom color
i3lock -c 2e1330

# lock it with a wallpaper
i3lock -c 000000 ~/Pictures/Wallpapers/mywallpaper.png

You can use your window manager or something more generic like xbindkeys to set a hotkey. This way you don’t have to open a terminal and type out the command every time you leave your desk. You can just press something like SUPER+L like you would on other OS’s.

Fancy #

If you like it a bit fancier, you can use i3lock-fancy, it can blur, pixelate, and greyscale your current screen. I did not really like this because you can still tell what is going on the screen. It’s probably secure enough and looks better, but I went with regular i3lock.

paru -S i3lock-fancy-git
# or
apt install i3lock-fancy

kubernetes node labels

2025-05-28T18:49:19Z

If you need to target a specific k8s node in the cluster, you can use labels. You want to treat your nodes as much like cattle as you can, but sometimes budgets get in the way. You might be like me and just run any free hardware you can get in your cluster, or you might have some large storage or gpu needs that you can’t afford to put on every node in the cluster.

kubectl get nodes --show-labels

# add the bigpool label
kubectl label node k8s-1 bigpool=true
kubectl get nodes --show-labels

# remove the bigpool label
kubectl label node k8s-1 bigpool-

To use the label in a pod set spec.nodeSelector to the label that you applied.

apiVersion: v1
kind: Pod
metadata:
  name: busybox
spec:
  containers:
  - name: busybox
    image: busybox
  nodeSelector:
    bigpool: "true"

javascript b64

2025-05-25T21:01:04Z

I’m currently [[replacing-google-search-apps-with-self-hosted-web-apps]] and decided to create a simple b64 encoder/decoder, just start typing to enter text, escape to deselect, then e/d to encode/decode.

I’m trying to make these apps super simple, self hosted out of minio, static html, and javascript. It’s been fun to get back to some simple interactive web development like this. No build just a website that does something. No broken builds, no containers to deploy, just push to minio.

encoded = btoa(content);
decoded = atob(encoded);

Here is the result.

web wakelock

2025-05-21T20:50:22Z

I’m trying to replace my usage of google inline search apps with real apps, today I used a stopwatch to time some things out at work by opening stopwatch. This was something I just wanted running in a tab on another screen, it was not timing running code or anything, I was using it as a reminder to check browser caches every 5 minutes or so for some testing.

So tonight I whipped up a stopwatch, clock and timer, all of which are using the wakelock API to keep the screen on while the app is running.

    // Wake Lock support
    let wakeLock = null;
    async function requestWakeLock() {
      try {
        if ('wakeLock' in navigator) {
          wakeLock = await navigator.wakeLock.request('screen');
          console.log("Wake lock acquired");
        }
      } catch (err) {
        console.error("Wake lock error:", err);
      }
    }

    document.addEventListener("visibilitychange", () => {
      if (wakeLock !== null && document.visibilityState === "visible") {
        requestWakeLock();
      }
    });

    requestWakeLock();

vhs themes

2025-05-16T08:24:51Z

I’ve been working on ninesui, inspired by k9s see thoughts-633. I want a good flow for making video for the readme and I am using charm.sh’s vhs for this. Its running in an archBTW distrobox and looks gawdaweful.

sort.mp4

The over saturated colors give it a really retro look, seems fine, but not my cup of tea. I tried to change the textual theme to tokyo-night and it might have made it a bit better, but still over-saturated.

After #

What I found is that vhs has themes, setting it to dracula made everything much better.

# sort.tape
Output assets/sort.mp4
Output assets/sort.gif

Require echo

Set Shell "bash"
Set FontSize 32
Set Width 1920
Set Height 1080
+ Set Theme 'Dracula'

sort.mp4

NinesUI #

I’m using these in my ninesui project, right now they are in the readme, but maybe some docs will grow eventually. Right now its hardcore explore phase.

grafana dashboards as k8s configmap

2025-05-06T20:24:35Z

I’m trying to learn proper logs, monitoring, otel, and grafana. Today I imported a bunch of pre-made k8s dashboards and made a few of my own for specific apps, and it made me want to know how I can turn my own custom dashboards into infrastructure as code. Turns out grafana makes it pretty easy to do this, if you have the grafana dashboard sidecar running. It will pick up any ConfigMap with the grafana_dashboard label and import it.

Go to Dashboards -> Pick a Dashboard -> Export -> JSON.

apiVersion: v1
kind: ConfigMap
metadata:
  name: my-dashboard
  namespace: meta
  labels:
    grafana_dashboard: "1"
data:
  my-dashboard.json: |
    {
      "annotations": {
        "list": [
      ...
      "uid": "fel2uhjhepg5ce",
      "version": 3
    }

ruff single line import

2025-05-04T14:23:41Z

I’ve been using ruff to lint my python code for quite awhile now, I was pretty early to jump on it after release. Some of my projects have had a nice force-single-line setting and some have not. I dug into the docs and it was not clear what I needed to make it work.

[tool.ruff]
select = ['I'] # you probably want others as well

[tool.ruff.isort]
force-single-line = true

Turns out I was missing Isort in the select list.

Markata list posts by year

2025-05-01T22:35:47Z

I was looking back at my analytics page today and wondered what were my posts about back at the beginning. My blog is managed by markata so I looked at a few ways you could pull those posts up. Turns out it’s pretty simple to do, use the markata map with a filter.

from markata import Markata

m.map('title, slug, date', filter='date.year==2016', sort='date')

Note

the filter is python eval that should evaluate to a boolean, all of the

attributes of the post are available to filter on.

Result #

[
    ('⭐ jupyterlab jupyterlab', 'jupyterlab-jupyterlab', datetime.date(2016, 12, 13)),
    ('⭐ nickhould tidy-data-python', 'nickhould-tidy-data-python', datetime.date(2016, 12, 9)),
    (
        '⭐ mikeckennedy write-pythonic-code-demos',
        'mikeckennedy-write-pythonic-code-demos',
        datetime.date(2016, 11, 22)
    ),
    (
        '⭐ mikeckennedy write-pythonic-code-for-better-data-science-webcast',
        'mikeckennedy-write-pythonic-code-for-better-data-science-webcast',
        datetime.date(2016, 11, 22)
    ),
    ('⭐ rajshah4 dlgroup', 'rajshah4-dlgroup', datetime.date(2016, 11, 18)),
    ('⭐ pandas-dev pandas', 'pandas-dev-pandas', datetime.date(2016, 10, 5))
]

You could use the list command as well right within your shell and the same map and filters work.

⬢ [devtainer-0.1.3] ❯ markata list --map title --filter='date.year==2016'
[22:35:06] 2088/2145 posts skipped                                                                       skip.py:36
           57/2145 posts not skipped                                                                     skip.py:37

⭐ pandas-dev pandas
⭐ rajshah4 dlgroup
⭐ mikeckennedy write-pythonic-code-for-better-data-science-webcast
⭐ mikeckennedy write-pythonic-code-demos
⭐ nickhould tidy-data-python
⭐ jupyterlab jupyterlab

You could also do it with jin right inside of a markdown post using the jinja_md plugin.

{% raw %}
{% for title, slug, date in markata.map('title, slug, date', filter='date.year==2016', sort='date') %}
* [{{title}}]({{slug}}) - {{date}}
{% endfor %}
{% endraw %}

Note

You do have to `jinja: true` in the frontmatter of the post.

Result #

{% for title, slug, date in markata.map(’title, slug, date’, filter=‘date.year==2016’, sort=‘date’) %}

{{title}} - {{date}} {% endfor %}

Use pbpaste for clean shell history

2025-03-17T12:00:00Z

Using pbpaste for command substitution keeps sensitive or long URLs out of your shell history. Instead of typing git clone https://github.com/user/repo-with-long-name.git, copy the URL to clipboard and run git clone "$(pbpaste)". This prevents the URL from appearing in ~/.bash_history or ~/.zsh_history.

To get pbpaste working on both Xorg and Wayland, add this to your shell config:

if [[ $(command -v wl-copy) ]]; then
    alias pbcopy='wl-copy'
    pbpaste() { wl-paste; }
elif [[ $(command -v xclip) ]]; then
    alias pbcopy='xclip -selection clipboard'
    pbpaste() { xclip -selection clipboard -o; }
fi

The function approach (instead of alias) enables command substitution, while the quotes around $(pbpaste) handle spaces and special characters safely.

Now you can use it.

git clone "$(pbpaste)"

More importantly secrets can stay out of your history.

export GITHUB_TOKEN="$(pbpaste)"
export AWS_ACCESS_KEY_ID="$(pbpaste)"
export AWS_SECRET_ACCESS_KEY="$(pbpaste)"
export DATABASE_URL="$(pbpaste)"

pre-commit exclude

2025-02-20T08:11:35Z

I run tailwind for my personal blog, whenever I update it, pre-commit goes in and fixes end of file. I’m sick of these things fighting each other, since it is a generated app it is going to et ignored from pre-commit from now on.

exclude: ^static/app.*\.css$
repos:
  - repo: https://github.com/pre-commit/pre-commit-hooks
    rev: v2.4.0
    hooks:

newlines in css before

2025-02-15T09:28:48Z

I’m building in a [[ fragmentions ]] implementation into my blog, I wanted to add some text before the fragment to indidate that it was the highlighted fragment that someone may have intended to share with you.

To get a newline in a :before I need to use \A and white-space: pre-line.

body :target::before,
body [fragmention]::before {
    content: "Highlighted Fragment:\A";
    white-space: pre-line;
    @apply font-bold text-yellow-600;
}

Here is what it looks like on my not yet live implementation of fragmentions.

testing nvim installs

2025-02-12T21:02:03Z

Testing fresh nvim installs can be a pain, and hard to di without borking your known good install. I’ve been using NVIM_APPNAME to run a test nvim in a sandbox that wont bork my main install. This usually runs for me in under a minute, can be down under 15s if I remove some of the TreeSitter installs at the end. This beats a full docker build of my full devtainer to test out nvim packaging woes.

rm ~/.cache/wwtest -rf
rm ~/.local/share/wwtest -rf
rm ~/.config/wwtest -rf
cp -r nvim/.config/nvim/ ~/.config/wwtest
NVIM_APPNAME=wwtest nvim --headless "+Lazy sync" +qa
NVIM_APPNAME=wwtest nvim --headless "+TSUpdateSync" "+sleep 5000m" +qa
NVIM_APPNAME=wwtest nvim --headless "+MasonUpdate" +qa
NVIM_APPNAME=wwtest nvim --headless "+TSInstallSync! c cpp go lua python rust tsx javascript typescript vimdoc vim bash yaml toml vue just" +qa
NVIM_APPNAME=wwtest nvim --headless "+MasonInstall lua-language-server rustywind ruff ruff-lsp html-lsp typescript-language-server beautysh fixjson isort markdownlint stylua yamlfmt python-lsp-server" +qa
NVIM_APPNAME=wwtest nvim

I’ve started to use this as a just recipe to run before deploying a new version of my dotfiles. So far its pairing nicely with nvim-manager

vim date

2025-02-12T12:51:00Z

When I want to put a date in a document like a blog post from vim I use !!date from insert mode. Note that entering !! from normal mode puts you in command mode with :.! filled out. This runs a shell command, i.e. date for this example.

It outputs the following

Fri Jan 31 08:46:11 PM CST 2025

You can also pass in a date such as tommorrow by pasdding in the -d date -d tomorrow.

It outputs the following

Sat Feb 1 08:53:20 PM CST 2025

codeium just taught me this one with autocomplete

:put =strftime('%Y-%m-%d')

This outputs the following

2025-01-31

What I like about the :put =strftime( method is that you can add a format, but that is a lot more for me to remember than !!date

A few weeks later #

I’m going through a bunch of blog posts and dont want my date formats to change to the Wed Feb format so I broke down and made these keybindings. I think I’m still going to be using .!date a lot, but these keybindings will be nice for editing blog post frontmatter.

set("n", "<leader>dd", "<cmd>put =strftime('%Y-%m-%d')<cr>", { noremap = true, silent = true })
set("n", "<leader>dt", "<cmd>put =strftime('%Y-%m-%d %H:%M:%S')<cr>", { noremap = true, silent = true })

dd 2025-02-12

aptitude why

2025-02-11T13:55:04Z

Today I ran into an interesting question, why am I being asked to configure tzdata while installing npm. Turns out that the aptitude cli has a why command that very handily nails down why you have something installed on a debian based system.

Install aptitude #

apt install aptitude

Why tzdata #

Now we can query why we need tzdata and see the full chain with the root package being npm.

root@47685221fb82:/# aptitude why tzdata
i   npm        Depends  node-gyp
i A node-gyp   Depends  gyp (>= 0.1+20200513gitcaa6002)
i A gyp        Depends  python3:any
i A python3    Provides python3:any
i A python3    Depends  python3.12 (>= 3.12.3-0~)
i A python3.12 Depends  tzdata

configure timezone

2025-02-10T13:35:24Z

Today I ran into this interactive prompt on ubuntu while installing node and npm, and I do not want to manually configure this interactively every time I run an install, moreso in docker I do not have the interactive terminal to do so.

Configuring tzdata
------------------

Please select the geographic area in which you live. Subsequent configuration questions will narrow this down by presenting a list of cities, representing the time zones in which they are located.

  1. Africa  2. America  3. Antarctica  4. Arctic  5. Asia  6. Atlantic  7. Australia  8. Europe  9. Indian  10. Pacific  11. Etc  12. Legacy
Geographic area:

Why tzdata #

Checking aptitude why tzdata it shows that the chain goes back through npm.

root@47685221fb82:/# aptitude why tzdata
i   npm        Depends  node-gyp
i A node-gyp   Depends  gyp (>= 0.1+20200513gitcaa6002)
i A gyp        Depends  python3:any
i A python3    Provides python3:any
i A python3    Depends  python3.12 (>= 3.12.3-0~)
i A python3.12 Depends  tzdata

The solution, configure tzdata #

export TZ="America/Chicago"
export DEBIAN_FRONTEND=noninteractive
apt update
apt install tzdata -y
ln -fs /usr/share/zoneinfo/$TZ /etc/localtime
dpkg-reconfigure -f noninteractive tzdata

DEBIAN_FRONTEND=noninteractive

This is required, because apt installing tzdata will trigger the

interactive prompt. You will manually configure it in the next two steps.

bc

2025-02-08T09:30:08Z

https://www.youtube.com/watch?v=03KsS09YS4E&t=610s

Today I learned about the basic calculator, bc. At the very end of this video prime uses it to add numbers in vim.

REPL #

You can start a calculator repl at the command line, by running bc.

Vim #

Since bc supports standard unix pipes you can easily pipe data from vim into bc and back out using !!bc. All you need is a string of math on the line you want to calculate, go to normal mode and run !!bc to get the answer.

Traditionally I will open my system calculator or ipython to do something like this.

To keep the equation and the result in the same line you can send the equation to stderr and the result to stdout using tee.

:.!tee >(cat >&2) | bc

tailwind aspect

2025-02-02T14:35:02Z

I’ve been back to putting some images on my blog lately and thinking about making them a bit thinner through the use of aspect ratio for simplicity. I’m leaning pretty heavy on tailwindcss these days due to some weird quirks of markdown-it-attrs I cannot have slashes in classes from markdown so I made a .cinematic class to achieve this.

.cinematic {
  @apply aspect-[2.39/1];
}

Example

markdown it attrs with slashes dont work

2025-02-01T11:21:10Z

Attrs does not like ‘/’ characters in its classes, so to use some tailwind classes with custom values we must make new classes in our tailwind input css.

.cinematic {
  @apply aspect-[2.39/1];
}

Given the following markdown with attrs added to the image and to the paragraph block.

![screenshot-2025-01-31T14-50-00-094Z.png](https://dropper.waylonwalker.com/api/file/50cfa8dc-9d46-4f02-877b-688fa5510a83.png){.aspect-[2.39/1]}

![screenshot-2025-01-31T14-50-00-094Z.png](https://dropper.waylonwalker.com/api/file/50cfa8dc-9d46-4f02-877b-688fa5510a83.png){.cinematic}

{.cinematic}
![screenshot-2025-01-31T14-50-00-094Z.png](https://dropper.waylonwalker.com/api/file/50cfa8dc-9d46-4f02-877b-688fa5510a83.png)

We get the following output with only the middle one working correctly.

{.aspect-[2.39/1]}

Note

The inline version of `.cinematic` works, but `.aspect-[2.39/1]` does not,

it turns into text after the image. The block version with the class before the image applies to the paragraph, not the image.

setting up nvim-manager starship prompt

2025-01-21T16:03:46Z

I built out a tool for myself to manage my nvim configuration, and I wanted to quickly see which one I am running in my starship prompt. Here’s the config I ended up with. It warns if the NVIM_APPNAME environment variable is not set, and it shows which nvim I am using if it is set.

[custom.nvim-manager-system]

emoji in headless chrome in docker

2025-01-20T13:55:37Z

I recently noticed that my og images were missing emoji. They were taken using headless chrome in a container. I fixed it by adding an emoji font in the containerfile / dockerfile.

RUN apt-get update && apt-get install -y \
    # Add fonts with emoji support
    fonts-noto-color-emoji \
    && rm -rf /var/lib/apt/lists/*

Before #

Here’s what they were looking like with broken emoji fonts.

After #

And now with the fixed emoji font.

I put thought bubbles on my thoughts posts and stars on my github stars posts

postiz-file-upload

2025-01-10T20:35:39Z

Today I learned that the docs in postiz are a bit behind, (fantastic docs btw, they are to the point, and cover almost all of what you need). The docs state that you need to include an R2 bucket to handle uploads.

This issue shows that more work has been done, one of which is local storage. The compose file they use in the quick start has the required env variables to set this up.

      STORAGE_PROVIDER: "local"
      UPLOAD_DIRECTORY: "/uploads"
      NEXT_PUBLIC_UPLOAD_DIRECTORY: "/uploads"

looking into my running instance I can see my images there.

Links rely on color to be distiniquishable

2024-12-17T20:25:12Z

Today i got hit by this accessibility issue on my site. Low contrast links are not distiniquishable. I had not seen this error title before it was new to me, maybe I have bad memory or maybe it’s new to me.

I ended up dropping the background color of the site down a notch as I didn’t really care for the semi-dark brown anyways. I’m liking the near black bg-zinc-950 much better now.

Now I got that 100 A11y score in lighthouse.

debug cloudflared tunnel

2024-12-03T15:36:37Z

I’ve been debugging a cloudflared tunnel issue in my homelab all day today, and getting really frustrated. My issue ended up being that it was running twice, once without the correct config file and another with it. I believe that cacheing may have compounded the issue.

In yesterday’s post I setup a cloudflared tunnel on my ubuntu server to expose applications running on the server to the internet. I’m setting up a new server and running cloudflared in its own vm.

setup cloudflared tunnel on ubuntu

Check that dns is pointing to the correct tunnel #

dig subdomain.example.com
traceroute subdomain.example.com

Check that the tunnel is running #

export CLOUDFLARED_TUNNEL_ID = "my-tunnel-id"

cloudflared tunnel list
cloudflared tunnel info $CLOUDFLARED_TUNNEL_ID

setup cloudflared tunnel on ubuntu

2024-12-02T15:43:45Z

I run a cloudflared tunnel on my ubuntu server to expose applications running on the server to the internet. I’m setting up a new server and running cloudflared in its own vm.

Get the cloudflared binary #

sudo wget https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-amd64 -O /usr/local/bin/cloudflared

sudo chmod +x /usr/local/bin/cloudflared

#

Now setup the config directory. For the systemd service to work, the config file needs to be in /etc/cloudflared. I like to give my user rights to edit the config file without being sudo, we will do that here by creating a group cloudflared, add ourselves to the group, give ownership of /etc/cloudflared to the group, give group write access to the directory, and refresh groups.

sudo mkdir -p /etc/cloudflared
sudo groupadd cloudflared
sudo usermod -aG cloudflared $USER
sudo chown -R root:cloudflared /etc/cloudflared
sudo chmod g+w /etc/cloudflared
newgrp cloudflared

Now we can log into the domain zone with cloudflared.

cloudflared tunnel login

This will give a url, follow it in a browser to log in.

cloudflared tunnel create <NAME>
mv ~/.cloudflared/cert.pem /etc/cloudflared/cert.pem
mv ~/.cloudflared/<tunnel-id>.json /etc/cloudflared/<tunnel-id>.json

config #

Now setup config. For the systemd service to work, the config file needs to be in /etc/cloudflared. The config that I have provided below will expose localhost:8000 to tester.example.com

export CLOUDFLARED_TUNNEL_ID=$(ls /etc/cloudflared/*.json | xargs -n 1 basename | sed 's/\.json$//')
mv ~/.cloudflared/${CLOUDFLARED_TUNNEL_ID}.json /etc/cloudflared/${CLOUDFLARED_TUNNEL_ID}.json
mv ~/.cloudflared/cert.pem /etc/cloudflared/cert.pem
echo "
tunnel: $(CLOUDFLARED_TUNNEL_ID)
credentials-file: /etc/cloudflared/$(CLOUDFLARED_TUNNEL_ID).json
ingress:
  - hostname: tester.example.com
    service: http://localhost:8000
  - service: 'http_status:404'
" >> /etc/cloudflared/config.yaml

dns #

Now to get a dns record for tester.example.com to point to the cloudflared tunnel.

cloudflared tunnel route dns $(CLOUDFLARED_TUNNEL_ID) tester.example.com

systemd #

Now install the systemd service.

sudo cloudflared service install

sudo systemctl status cloudflared.service
# if its not running
sudo systemctl start cloudflared.service

price an stl print on slant3d

2024-11-18T15:29:30Z

I’ve been playing with 3d printing some items through the slant3d api. I’ve been pricing out different prints by running a slice request through their api.

make a project #

I’ve been using uv for project management. It’s been working well for quick projects like this while making it reproducible, I’m still all in on hatch for libraries.

mkdir slantproject
cd slantproject
uv init
uv venv
. ./.venv/bin/activate
uv add httpx rich python-dotenv

Get an api key #

You will need an api key from the slant api, which currently requires a google account and a credit card to create.

# .env
#  replace with your api key from https://api-fe-two.vercel.app/
SLANT_API_KEY=sl-**

slicing an stl with teh slant api #

Then you can run the python script to price out your print. I’m not exactly sure how this compares to an order, especially when you add in different materials.

from dotenv import load_dotenv
import httpx
import os

load_dotenv()

stl_url = ''
api_key = os.environ["SLANT_API_KEY"]

api = httpx.Client(base_url="https://www.slant3dapi.com/api/slicer")

res = httpx.post(
    "https://www.slant3dapi.com/api/slicer",
    json={"fileURL": stl_url},
    headers={"api-key": api_key, "Content-Type": "application/json"},
    timeout=60,
)


print(res.json())

k3s config after first install

2024-09-15T16:57:41Z

After first setting up a new k3s instance your kubeconfig file will be located in /etc/rancher/k3s/k3s.yaml.

You cans use it from here by setting $KUBECONFIG to that file.

export KUBECONFIG=/etc/rancher/k3s/k3s.yaml

Or you can copy it to ~/.kube/config

cp /etc/rancher/k3s/k3s.yaml ~/.kube/config

If you have installed k3s on a remote server and need the config on your local machine then you will need to modify the server address to reflect the remote server.

scp user@<server-ip>:/etc/rancher/k3s/k3s.yaml ~/.kube/config

Warning

only do this if you don’t already have a ~/.kube/config file, otherwise copy it to a new file and set your $KUBECONFIG env variable to use it.

Now you will need to open that file and change the server address, making sure to keep the port number.

apiVersion: v1
clusters:
  - cluster:
      certificate-authority-data: ****
      server: https://<server-ip>:6443

Vim-gq

2024-08-05T12:22:00Z

Vim has a handy feature to format text with gq. You can use it in visual mode, give it a motion, or if you give it gqq it will format the current line. I use this quite often while writing in markdown, I do not use softwraps in vim, so gqq quickly formats my current line into a paragraph. Once I have done this for a single line one time I typically switch to the motion for around paragraph gqap to format the whole paragraph and not just the current line.

Slug

2024-08-05T11:45:00Z

A slug is the part of the url that comes after the domain. Commonly matches the file name of a markdown file many blogging systems. These are typically human readable, unique identifiers for pages within the site.

Obsidian-new-file

2024-08-05T11:44:00Z

Wikilinks are a core concept within obsidian to link to documents by Slug wrapped in double square brackets. These are commonly used within wiki site generators.

[[slug]]

Obsidian gives you a keybinding alt+enter to go to that file, but if it does not exist it will create the file for you in the root of the project. It’s a nice way to quickly make new documents.

Obsidian-go-to-definition

2024-08-04T20:35:00Z

It was not obvious to me, but if you have a wikilink such as Trying Obsidian, you can jump to the file in obsidian, just like you can with lsp go to definition, the keybinding is alt + enter.

Obsidian Using Templater Like Copier

2024-07-31T13:34:00Z

I’ve long used copier to create all of my posts for my blog, and it works really well for my workflow. I think of a title, call a template, and give it a title. out of the box obsidian did not seem to work this way. It seems like it wants me to right click a file tree and make a new file using the tree, this is not my jam.

Here is what I came up with to replace my til template.

---
date: <% tp.file.creation_date() %>
templateKey: til
title: <%*
  const originalFileName = await tp.system.prompt("Enter file name");
  const toTitleCase = str => str.replace(
    /\w\S*/g,
    txt => txt.charAt(0).toUpperCase() + txt.substr(1).toLowerCase()
  );
  const title = toTitleCase(originalFileName);
  tR += title + '\n'; // Add the title to the template result
-%>
published: true
tags:
  -
---
<%*
const fileName = originalFileName.toLowerCase().replace(/\s+/g, '-');
const newFilePath = `pages/til/${fileName}`;
await tp.file.move(newFilePath);
-%>

<% tp.file.cursor() %>

tR is a return value, and it gets placed directly into the place it is in the file
to.file.cursor() creates a tab-index point so I can tab into the content

Obsidian Image Converter

2024-07-30T21:09:35Z

I’m giving obsidian a go as an editor for my blog and one of the main things I want to fix in my workflow is the ability to quickly drop in images. on first look through the community plugins I found Image Converter. I set it up to convert to webp and drop them in a git submodule. I may make it something other than a git repo in the future, but I’ve learned that adding images to my blog repo quickly makes it heavy and hard to clone on other machines.

Once the images are there they are pushed and deployed as their own site to cloudflare pages. I made a quick edit to my sick wikilink hover plugin for my blog. if it sees a wikilink ending in webp, convert the domain over to obsidian-assets.waylonwalker.com, and clean up the remaining "! " that the python md-it library leaves behind.

Note

after first try I needed to increase the width from 600 to 1400, the image in this post was unreadable.

This is part of me getting set up and Trying Obsidian

k8s kustomize diff

2024-07-06T09:42:42Z

I’ve started leaning in on kubernetes kustomize to customize my manifests per deployment per environment. Today I learned that it comes with a diff command.

kubectl diff -k k8s/overlays/local

You can enable color diffs by using an external diff provider like colordiff.

export KUBECTL_EXTERNAL_DIFF="colordiff -N -u"

You might need to install colordiff if you don’t already have it.

sudo pacman -S colordiff

sudo apt install colordiff

Now I can try out kustomize changes and see the change with kustomize diff.

kubectl dash k

2024-07-05T20:15:11Z

Kubernetes ships with a feature called kustomize that allows you to customize your manifests in a declarative way. It’s a bit like helm, but easier to use. I found this useful.

kustomization.yaml #

In order to use kustomize you need to have a kustomization.yaml, kustomization.yml, or Kustomization file in the directory you are applying.

kubectl apply -k .
error: unable to find one of 'kustomization.yaml', 'kustomization.yml' or 'Kustomization' in directory '/tank/git/kustomize-playground'

The kustomization.yaml file cannot be empty.

❯ kubectl apply -k pod
error: kustomization.yaml is empty

lets make an mvp #

mkdir pod
touch pod/pod.yaml
touch pod/kustomization.yaml

# pod.yaml

# kustomization.yaml

Overlays #

Overlays must point to yaml or a directory with a kustomization.yaml file, and cannot reside inside the same directory causing a circular reference.

Layout #

k8s
├── base
│   ├── deployment.yaml
│   └── kustomization.yaml
├── overlays
│   ├── local
│   │   └── kustomization.yaml
│   ├── dev
│   │   └── kustomization.yaml
│   └── prod
│       ├── special-prod.yaml
│       └── kustomization.yaml

base #

Place all of the common k8s manifests here in the base directory along with kustomization.yaml. You can split them up into separate files or just one file, I’m keeping it to one for simiplicity.

base - kustomization.yaml #

In the base kustomization.yaml file add all of the manifests that you want to use as a resource.

resources:
  - deployment.yaml

overlays #

Now for each separate environment that you want to have create a directory in overlays with a kustomization.yaml file, and any special manifests that only apply to a particular environment.

overlays - kustomization.yaml #

resoures #

resources:
  - ../../base
# any other specific resources, maybe special ones for prod here
  - sealed-dotenv.yaml

images #

images:
  - name: my-image
    newName: docker.io/myrepo/myimage

animal well keyboard

2024-07-04T21:58:41Z

Animal well does not let you remap keys, and really doesn’t even inform you that it is keyboard compatible. I had to play around and discover the keymap, which can be a bit tricky on a 40% board. This is what I found.

wasd - move
space - jump / a
enter - interact / b
x - throw
c - inventory
1 - left item / rb

diskcache as debounce

2024-07-03T11:14:11Z

I’ve been using fastapi more and more lately and one feature I just started using is background tasks [[ thoughts-333 ]].

Seealso

basic diskcache example <a href="/python-diskcache/" class="wikilink" data-title="How I setup a sqlite cache in python" data-description="When I need to cache some data between runs or share a cache accross multiple processes my go to library in python is . It&#39;s built on sqlite with just enough..." data-date="2022-03-29">How I setup a sqlite cache in python</a>

One Background Task per db entry #

I am using it for longer running tasks and I don’t want to give users the ability to spam these long running tasks with many duplicates running at the same time. And each fastapi worker will be running in a different process so I cannot keep track of work in memory, I have to do it in a distributed fashion. Since they are all running on the same machine with access to the same disk, diskcache is a good choice

What I need #

check if a job is running
automatically expire jobs

Less infrastructure complexity #

My brain first went to thinking I needed another service like redis running alongside fastapi for this, then it hit me that I can use diskcache.

How I used diskcache #

Here is how I used diskcache to debounce taking screenshots for a unique shot every 60 seconds.

from diskcache import Cache

jobs_cache = Cache("jobs-cache")

@shots_router.get("/shot/{shot_id}", responses={200: {"content": {"image/webp": {}}}})
@shots_router.get("/shot/{shot_id}/", responses={200: {"content": {"image/webp": {}}}})
async def get_shot_by_id(
    background_tasks: BackgroundTasks,
    request: Request,
    shot_id: int,
):
    shot = Shot.get(shot_id)
    # check if the shot exists and return it or continue to create it.



    is_running = jobs_cache.get(shot_id)

    if is_running:
        expire_time = datetime.fromtimestamp(jobs_cache.peekitem(expire_time=True)[1]) - datetime.now()
        console.print("[red]Already running store_shot: ", shot_id)
        console.print(f"[red]Can retry in {expire_time.seconds}s")
    else:
        jobs_cache.set(shot_id, True, 60)
        background_tasks.add_task(
            store_shot,
            shot_id=shot_id,
        )

Install sealed-secreats via manifest

2024-07-02T07:54:01Z

Yesterday I realized that I have overlooked the default installation method of the sealed secrets controller for kubernetes kubeseal this whole time an jumped straight to the helm section. I spun up a quick kind cluster and had it up quickly. I can’t say this is any better or worse than helm as I have never needed to customize the install. According to the docs you can customize it with [[ kustomize ]] or helm.

# option if you don't have a cluster try with kind

kind create cluster

curl -L https://github.com/bitnami-labs/sealed-secrets/releases/download/v0.27.0/controller.yaml > controller.yaml

playerctl fixes arch media keys

2024-06-25T18:23:41Z

I’ve long had issues with my qmk keyboard media keys on my arch install, I always thought it was on the keyboard end. Today I learned that playerctl fixes this.

paru -S playerctl

Once it is installed all of my media keys started working right away.

I played around with it a bit more and came up with a way to display the current playing title in my notifictations.

notify-send "`playerctl metadata --format '{{lc(status)}}:{{artist}}-{{album}}-{{title}}'`"

tailwind post template

2024-06-08T14:47:42Z

Today I am playing around with tailwind, flexing the css muscle and learning how to build new and different layouts with it.

I created a new post template that mimics a terminal look in css where I could inject the post title, description, and other frontmatter elements.

I think this is a pretty cool layout, I could make a carbon.now.sh{.hoverlink} clone or more realistically I could make it into a template for blog pages and this could become og images.

Still Loving Tailwind

tailscale ssh

2024-06-03T16:40:18Z

Tailscale allows you to ssh into all of your tailscale machines, it busts through firewalls and accross networks without complex setup. If you have used tailscale before this is an obvious no brainer. What is not obvious is that you can configure tailscale to allow ssh connections from devices within your tailnet without even a ssh daemon process running right through the tailscale daemon.

tailscale status
tailscale set --ssh

I picked this up from the tailscale youtube channel.

Latest Page in Markata

2024-06-01T21:01:26Z

I just implemented a latest blog post link in Markata by asking for the first post slug from the blog feed. The implementation uses the jinja_md plugin to render jinja against the markdown and a tag to redirect.

My latest blog post is [[ {{ markata.feeds.blog.posts[0].slug }} ]].  Click the
link if you are not automatically redirected.

<meta http-equiv="Refresh" content="0; url='/{{ markata.feeds.blog.posts[0].slug }}'" />

Setting up the feed #

Feeds are setup in markata.toml configuration. They provide a handy way to create an html feed, rss feed, and quickly reference a filtered set of posts like this.

# you will need to enable the jinja_md plugin along with the defaults
[markata]
hooks = [
    "markata.plugins.jinja_md",
    "default",
    ]

# set up the blog feed
[[markata.feeds]]
slug = 'blog'
template = "feed.html"
filter = "date<=today and templateKey in ['blog-post'] and published"
sort = "date"
reverse = true

How to List Sqlite tables

2024-04-23T20:03:27Z

You can inspect sqlite tables with the sqlite shell.

note that you get into the shell with sqlite3 database.db

.tables

I also learned that .tables, .index and .schema are helper functions that query the sqlite_master table on the main database.

Here is an output from my redka database. The sqlite_master table contains all the sqlite objects type, name, tbl_name, rootpage, and sql to create them.

With the liscense changes to redis there are several new forks out there. One that I am particularly interested in is redka.

curl https://i.jpillora.com/nalgeon/redka | bash
chmod +x redka
./redka database.db

We now have redis running on port 6379 that we can connect to with a redis client. And we have a sqlite database that we can inspect.

❯ sqlite3 database.db "SELECT name FROM sqlite_master;"
rkey
rkey_key_idx
rkey_etime_idx
rkey_on_type_update
rstring
rstring_pk_idx
vstring
rhash
rhash_pk_idx
rhash_key_id_idx
vhash

We can look at the values in the vstring table.

sqlite3 database.db "SELECT * from vstring;"

Am I vulnerable to the xz backdoor?

2024-04-21T07:53:54Z

The main system that I am concerned about is my arch BTW machine. I found a great article from the official archlinux site covering it.

For my machine I am concerned with this line.

The xz packages prior to version 5.6.1-2 (specifically 5.6.0-1 and 5.6.1-1) contain this backdoor.

I checked my xz package with AUR.">paru, and I am good.

paru -Qii zx

AUR.">paru has some nice features that I rarely use, and hav to look up when I need them. Here are two commands to help with dependency management.

copier trust

2024-04-19T20:41:06Z

I recently had to update my copier-gallery command to trust my own templates because some of them have shell scripts that run afterwards. Be warned that this could be a dangerous feature to run on random templates you get off the internet, but these are all mine, so if I wreck it its my own fault.

copier copy --trust <template> <destination>

All the the copier copy api can be found with help.

❯ copier copy --help
copier copy 8.3.0

Copy from a template source to a destination.

Usage:
    copier copy [SWITCHES] template_src destination_path

Hidden-switches:
    -h, --help                         Prints this help message and quits
    --help-all                         Prints help messages of all sub-commands and quits
    -v, --version                      Prints the program's version and quits

Switches:
    -C, --no-cleanup                   On error, do not delete destination if it was
                                       created by Copier.
    --UNSAFE, --trust                  Allow templates with unsafe features (Jinja
                                       extensions, migrations, tasks)
    -a, --answers-file VALUE:str       Update using this path (relative to
                                       `destination_path`) to find the answers file
    -d, --data VARIABLE=VALUE:str      Make VARIABLE available as VALUE when rendering the
                                       template; may be given multiple times
    -f, --force                        Same as `--defaults --overwrite`.
    -g, --prereleases                  Use prereleases to compare template VCS tags.
    -l, --defaults                     Use default answers to questions, which might be
                                       null if not specified.
    -n, --pretend                      Run but do not make any changes
    -q, --quiet                        Suppress status output
    -r, --vcs-ref VALUE:str            Git reference to checkout in `template_src`. If you
                                       do not specify it, it will try to checkout the
                                       latest git tag, as sorted using the PEP 440
                                       algorithm. If you want to checkout always the
                                       latest version, use `--vcs-ref=HEAD`.
    -s, --skip VALUE:str               Skip specified files if they exist already; may be

                                       folders that must not be copied; may be given
                                       multiple times

ipython f2

2024-04-18T20:40:41Z

Today I accidentally ran f2 in ipython to discover that it opens your $EDITOR! I use this feature quite often in zsh, it is bound to <c-e> for me, and since I have my environment variable EDITOR set to nvim it opens nvim when I hit <c-e>. Today I discovered that Ipython has this bound to F2. If you know how to set it to <c-e> let me know I’ve tried, a lot.

export EDITOR=nvim
ipython
<F2>

better yet add export EDITOR=nvim to your .zshrc

# ~/.zshrc
export EDITOR=nvim

sqlmodel indexes

2024-04-17T21:55:25Z

I’ve really been enjoying using sqlmodel for my projects that need a database. One thing that I definitely lacked on for too long was indexing my database. I hit a point with one database where it was taking 7s for pretty simple paginated queries to return 10 records.

For every field that you will be querying on, you can create an index, by setting it equal to Field(index=True)

class Hero(SQLModel, table=True):
    id: int | None = Field(default=None, primary_key=True)
    name: str = Field(index=True)
    secret_name: str
    age: int | None = Field(default=None, index=True)

example courtesy of the docs

Note

 primary keys are indexed by default.

The docs cover this pretty well, and in quite depth - Optimizing Queries

python inline snapshot

2024-04-17T13:32:53Z

inline-snapshot is a new tool that I am trying out for python testing. It takes snapshots of your outputs and places them inline with the test.

Here is the most basic starter.

import inline_snapshot

def test_one():
    assert 1 == snapshot()

Now when I run pytest my tests will fail because my assert has no value, but if I run pytest --inline-snapshot=create it will fill out my snapshot values and the file will then look like this.

import inline_snapshot

def test_one():
    assert 1 == snapshot(1)

It also works with pydantic models.

class MyModel(BaseModel):
    name: str
    age: int
    nickname: str | None = None


def test_my_model_instance():
    assert MyModel(name="Waylon", age=1) == snapshot(MyModel(name="Waylon", age=1))


def test_my_model_fields():
    me = MyModel(name="Waylon", age=1, nickname='Waylon')
    assert me.name == snapshot("Waylon")
    assert me.age == snapshot(1)
    assert me.nickname == snapshot("Waylon")

sqlite vacuum

2024-04-16T21:31:24Z

Today I learned how to VACUUM a sqlite database and cut its size in about half. It’s a database that I have had running for quite awhile and has some decent traffic on it.

Why is it important to do a VACUUM? In short its becuase the file system gets fragmented with as data is updated. On delete the files are removed from the database and marked as available for reuse in the filesystem, but the space is not reclaimed.

To VACUUM a database, run the following sql command. You can do it right form the sqlite shell by running sqlite3.

You will need about double the current size of the database as free space to do the VACUUM, you need space for a full copy, journaling or write ahead logs, and the existing database.

VACUUM;

The docs are fantastic for vacuum.

Tailwind Animations

2024-04-15T21:19:21Z

I learned that tailwind animations are pretty easy to add only needing a few classes. For some reason though my brain broke, thinking that I could dynamically change the number and you can’t cause there are only so many pre compiled classes without using an arbitrary value with brackets.

Here are the classes that I used to transition my colors very slowly.

<div id="square"
      class="transition-colors ease-in-out duration-700">
</div>

And the entire square element.

<div id="square"
      class="w-16 h-16 bg-rose-500 rounded border border-4 border-rose-800 hover:bg-indigo-600 hover:border-yellow-500 transition-colors ease-in-out duration-700">
</div>

How to kill ollama server

2024-04-14T18:31:36Z

I recently updated ollama, and it now installs a systemd service that I was not expecting. Seems like a great option, but I hadn’t expeted this and I was able to kill it previously. It was using up gpu, and I do other things on my machine with a gpu. I tried pkill, kill, and everything, it was still coming back.

No matter what it comes back

# stop it
systemctl stop ollama.service

# disable it if you want
systemctl disable ollama.service

# confirm its status
systemctl status ollama.service

You can confirm this with the following command.

# checking running processes
ps aux | grep ollama
pgrep ollama

# checking gpu processes
gpustat --show-cmd --show-pid

Next time you want to start you can do it as before with ollama serve.

Composing Typer clis

2024-04-13T08:27:26Z

Typer makes it easy to compose your cli applications, like you might with a web router if you are more familiar with that. This allows you to build smaller applications that compose into a larger application.

You will see similar patterns in the wild, namely the aws cli which always has the aws <command> <subcommand> pattern.

Lets setup the cli app itself first. You can put it in project/cli/cli.py.

import typer

from project.cli.api import api_app
from project.cli.config import config_app
from project.cli.user import user_app
from project.cli.run import run_app

app = typer.Typer()

app.add_typer(api_app, name="api")
app.add_typer(config_app, name="config")
app.add_typer(user_app, name="user")
app.add_typer(run_app, name="run")

Creating an app that will become a command is the same as creating a regular app in Typer. We need to create a callback that will become our command, and a command that will become our subcommand in the parent app.

import typer
from rich.console import Console

from project.config import get_config

config_app = typer.Typer()

@config_app.callback()
def config():
    "model cli"


@config_app.command()
def show(
):
    project_config = get_config(env)
    Console().print(fokais_config)

Setting up the entrypoint in pyproject.toml.

[project.scripts] # <- this project is part of the config DO NOT change it
project = "project.cli.cli:app" # <- This project is the project name, DO change it

Now you can see each cli application as a sub command.

❯ project --help

 Usage: project [OPTIONS] COMMAND [ARGS]...

In the example above we can run the command project config show to see the current configuration of our project.

tailwind arbitrary values

2024-04-12T21:21:42Z

I learned not to fear the arbitrary size feature of tailwind. While building out reader.waylonwalker.com I kept getting content flowing off the screen, and struggling to keep it on the screen. I really felt that I should be able to do this with vanilla tailwind, but after some encouragement from Twitter I decided to lean on arbitrary values and it worked.

Don’t fear the arbitrary values.

fix npm global install needs sudo

2024-04-11T13:28:17Z

Each time I go to set up npm I am frustrated by the errors saying that I don’t have permission to npm i -g <package>, and it’s frustrating. And I forget what I need to do to tell npm to install packages in a directory I own, and my shell to look there so that I can use the executables.

mkdir ~/.npm-global
export NPM_CONFIG_PREFIX=~/.npm-global
export PATH=$PATH:~/.npm-global/bin

For the fix to remain persistent you need to put these two lines in your shell profile like ~/.bashrc or ~/.zshrc.

export NPM_CONFIG_PREFIX=~/.npm-global
export PATH=$PATH:~/.npm-global/bin

darkmode scrollbars

2024-04-10T11:56:38Z

If you are designing a website in dark mode the scrollbars can be finicky to match the theme. Here is a pretty sane default that looks nice without being obnoxiously contrast to the rest of the site.

    <style>
        ::-webkit-scrollbar {
            height: 1rem;
            width: 1rem;
        }

        ::-webkit-scrollbar-track {
            background-color: rgb(24 24 27);
        }

        body::-webkit-scrollbar-track {
            background-color: rgb(39 39 42);
        }

        ::-webkit-scrollbar-thumb {
            background-color: rgb(82 82 91);
        }

        ::-webkit-scrollbar-thumb:hover {
            background-color: rgb(113 113 122);
        }

        body::-webkit-scrollbar-thumb {
            background-color: rgb(82 82 91);
        }

        body::-webkit-scrollbar-thumb:hover {
            background-color: rgb(113 113 122);
        }

        ::-webkit-scrollbar-corner {
            background-color: rgb(39 39 42);
        }
    </style>

Want a rounded scrollbar thumb? add these styles.

::-webkit-scrollbar-thumb {
    border-radius: 0.25rem;
    border-radius: 9999px;
}

body::-webkit-scrollbar-thumb {
    border-radius: 0.25rem;
    border-radius: 9999px;
}

This makes a very nice looking default darkmode scrollbar.

Udating Cloudflare Pages using the Wrangler cli

2024-04-09T17:03:51Z

Before deploying to cloudflare pages with wrangler you need a cloudflare api token. You can get one at dash.cloudflare.com/profile/api-tokens.

Install Wrangler #

Next install wrangler using npm.

npm i -g wrangler

Create a Project #

Before you deploy to cloudflare pages you need to create a project. You might already have one, or you might want to create one in the webui, but you have the option to create it at the command line with wrangler.

npx wrangler pages deploy markout --project-name reader-waylonwalker-com --branch markout

Deploy #

Now you can deploy your static application using wrangler to cloudflare pages.

In this example I have my application built into the markout directory, and since the production branch is named markout I need to pass that in here as well.

wrangler pages deploy markout --project-name reader-waylonwalker-com --branch markout

scheduling cron jobs in kubernetes

2024-04-08T16:56:46Z

For my reader app I am using cronjobs to schedule my a new build and upload to cloudflare pages every hour. In this example I have built a docker image docker.io/waylonwalker/reader-waylonwalker-com and pushed it to dockerhub. It uses a CLOUDFLARE_API_TOKEN secret to access cloudflare, and the entrypoint itself does the build and upload.

apiVersion: v1

  creationTimestamp: null
  name: reader
  namespace: reader

jinja macros

2024-04-07T14:54:08Z

I am working on a page for htmx-patterns and I ran into a situation with lots of duplication. Especially when i am using tailwind I run into situations where the duplication can get tedious to maintiain. The solution I found is macros.

Now I can use the same code for all of my links, and call the macro to use it.

{% macro link(id, text, boosted=false) -%}
<a
    class="
    {% if id is none %}
      pointer-events-none bg-terminal-950 text-terminal-900 ring-terminal-900
    {% else %}
      bg-terminal-950 hover:bg-terminal-900 hover:text-terminal-400 text-terminal-500 shadow-lg shadow-terminal-300/20 hover:shadow-terminal-300/30 ring-terminal-300
    {% endif %}
      cursor-pointer block text-center font-bold py-2 px-4 rounded w-full ring-1
    "
    {% if id is not none %}
    href="{{ url_for('boosted', id=id) }}"
    {% endif %}
    {% if boosted %}
    hx-boost="true"
    {% endif %}>
    {{ text }}
</a>
{%- endmacro %}

<h2 class='text-3xl font-light mt-0 max-w-xl text-center prose-xl mt-8 text-terminal-500'>
    Boosted Links
</h2>

<div class='flex flex-row gap-4'>
    {{ link(prev_id, 'Previous', boosted=True) }}
    {{ link(next_id, 'Next', boosted=True) }}
</div>

<h2 class='text-3xl font-light mt-0 max-w-xl text-center prose-xl mt-8 text-terminal-500'>
    Normal Links
</h2>

<div class='flex flex-row gap-4'>
    {{ link(prev_id, 'Previous', boosted=False) }}
    {{ link(next_id, 'Next', boosted=False) }}
</div>

jinja loop variable and htmx

2024-04-06T20:47:13Z

jinja has a loop variable that is very handy to use with htmx. Whether you want to implement a click to load more or an infinite scroll this loop variable is very handy.

{% for person in persons %}
<li
{% if loop.last %}
    hx-get="{{ url_for('infinite', page=next_page) }}"
    hx-trigger="intersect once"
    hx-target="#persons"
    hx-swap='beforeend'
    hx-indicator="#persons-loading"
{% endif %}
    {{ person.name.upper() }} -
    {{ person.phone_number }}
</li>
{% endfor %}

Now for every chunk of contacts that we load we will trigger the infinite scroll by loading more once the last one has intersected the screen.

fastapi jinja url_for with query params

Out of the box FastAPI.">Starlette does not support url_for with query params. When trying to use url_for with query params it throws the following error.

starlette.routing.NoMatchFound: No route exists for name "infinite" and params "page"

In my searching for this I found starlette issue #560 quite helpful, but not complete, as it did not work for me.

import jinja2

if hasattr(jinja2, "pass_context"):
    pass_context = jinja2.pass_context
else:
    pass_context = jinja2.contextfunction

@pass_context
def url_for_query(context: dict, name: str, **params: dict) -> str:
    request = context["request"]
    url = str(request.url_for(name))
    if params == {}:
        return url
    from urllib.parse import parse_qs, urlencode, urlparse, urlunparse

    # Parse the URL
    parsed_url = urlparse(url)

    # Parse the query parameters
    query_params = parse_qs(parsed_url.query)

    # Update the query parameters with the new ones
    query_params.update(params)

    # Rebuild the query string
    updated_query_string = urlencode(query_params, doseq=True)

    # Rebuild the URL with the updated query string
    updated_url = urlunparse(
        (
            parsed_url.scheme,
            parsed_url.netloc,
            parsed_url.path,
            parsed_url.params,
            updated_query_string,
            parsed_url.fragment,
        )
    )

    if os.environ.get("ENV") in ["dev", "qa", "prod"]:
        updated_url = updated_url.replace("http", "https", 1)

    return updated_url

def get_templates():
    templates = Jinja2Templates(directory="templates")
    templates.env.globals["url_for"] = url_for_query
    return templates

https

 If you want url_for to work in production you need some way to convert http

to https. Here is how I make it work, for local development I export ENV=local then for each environment that I am running on a server I include it in the list and update ENV appropriately.

    if os.environ.get("ENV") in ["dev", "qa", "prod"]:
        updated_url = updated_url.replace("http", "https", 1)

The route might look something like this.

@infinite_router.get("/")
async def home(request: Request, page: int = 1, n: int = 10):
  ...

To access the home route using url_for in a jinja template you can use the following, once you have applied the url_for_query function as your default url_for

<a href="{{ url_for('home', page=1) }}">Home</a>

setting up a kind cluster with argocd installed

2024-04-04T18:42:18Z

Kind (Kubernetes in Docker) is a tool that makes it easy to create and tear down local clusters quickly. I like to use it to test out new workflows.

Argocd is a continuous delivery tool that makes it easy to setup gitops workflows in kubernetes.

Here is how you can setup a new kind cluster and install argocd into it using helm, the kubernetes package manager.

kind create cluster --name argocd

# your first time through you need to add the argocd repo
helm repo add argo https://argoproj.github.io/argo-helm
helm repo update

# install argocd into the cluster
helm install argo argo/argo-cd --namespace argocd --create-namespace

# deploy the app of apps
kubectl apply -f apps/apps.yaml

If you want to add repos and apps to your cluster you can use the argo cli to do that, but first you will need forward the argocd port and login.

# Wait until Argo CD API server is available
echo "Waiting for Argo CD API server to be available..."
while ! kubectl wait --for=condition=available --timeout=60s deployment/argo-argocd-server -n argocd; do
  echo "Waiting for Argo CD API server to be ready..."
  sleep 10
done


kubectl port-forward svc/argo-argocd-server -n argocd 8080:443 &
argocd_admin_password=$(kubectl get secret argocd-initial-admin-secret -n argocd -o jsonpath="{.data.password}" | base64 -d)
argocd login localhost:8080 --insecure --username admin --password $argocd_admin_password
argocd repo add https://github.com/fokais-com/app.fokais.git --username waylonwalker --password ${GH_ARGO_PAT}
argocd app create app-fokais-local --repo https://github.com/fokais-com/app.fokais.git --path k8s/overlays/local --dest-server https://kubernetes.default.svc --sync-policy automated --sync-option Prune=true

kubernetes kubeseal

2024-03-27T20:02:57Z

In my homelab kubernetes cluster I am using kubeseal to encrypt secrets. I have been using it successfully for a few months now wtih great success. It allows me to commit all of my secrets manifests to git with out risk of leaking secrets.

You see kubeseal encrypts your secrets with a private key only stored in your cluster, so only the cluster itself can decrypt them using the kubeseal controller.

KubeSeal #

https://sealed-secrets.netlify.app/

installation #

Installation happens in two steps. You need the kubernetes controller and the client side cli to create a sealed secret.

For a more complete instruction see the [docs#installation](https://github.com/bitnami-labs/sealed-secrets?tab=readme-ov-file#installation]

installation - controller #

Warning

 **context**

Make sure that you are in the right context before running any kubectl commands.

kubectl config current-context

sealed-secrets is installed using the helm package manager. To install sealed-secrets run the following command.

helm repo add sealed-secrets https://bitnami-labs.github.io/sealed-secrets
helm install sealed-secrets -n kube-system --set-string fullnameOverride=sealed-secrets-controller sealed-secrets/sealed-secrets

installation - client #

For the client you can check your OS package manager, brew, or the github-releases. For me I found it in the main arch repos.

paru -S kubeseal
# or
sudo pacman -S kubeseal
# or
brew install kubeseal

Note

 You will need to install kubeseal on every device that you will want to

create sealed secrets on.

Example #

Most of these commands come straight from the docs. From my experience I have always specified the namespace, my projects go per namespace and I don’t have any reason that other namepsaces should see the secret, and if they do I deploy another secret in that namespace.

# Create a json/yaml-encoded Secret somehow:
# (note use of `--dry-run` - this is just a local file!)
echo -n bar | kubectl create secret generic mysecret --dry-run=client --from-file=foo=/dev/stdin -o yaml -n thenamespace > mysecret.yaml

note that the key of the secret is foo and the value is bar

results

apiVersion: v1
data:
  foo: YmFy
kind: Secret
metadata:
  creationTimestamp: null
  name: mysecret
  namespace: thenamespace

Note

 The data is base64 encoded.

echo -n bar | base64
# YmFy

# This is the important bit:
kubeseal -f mysecret.yaml -w mysealedsecret.yaml

# At this point mysealedsecret.json is safe to upload to Github,
# post on Twitter, etc.

# Eventually:
kubectl create -f mysealedsecret.yaml -n thenamespace
# sealedsecret.bitnami.com/mysecret created

# Profit!
kubectl get secret mysecret
kubectl get secret mysecret -n thenamespace
# NAME       TYPE     DATA   AGE
# mysecret   Opaque   1      27s

cat mysealedsecret.yaml | kubeseal --validate

echo -n bar | kubectl create secret generic mysecret --dry-run=client --from-file=foo=/dev/stdin -o yaml \
  | kubeseal -o yaml -n thenamespace > mysealedsecret.yaml
echo -n baz | kubectl create secret generic mysecret --dry-run=client --from-file=bar=/dev/stdin -o yaml \
  | kubeseal -o yaml -n thenamespace --merge-into mysealedsecret.yaml

backing up your sealing key #

kubectl get secret -n kube-system -l sealedsecrets.bitnami.com/sealed-secrets-key -o yaml >main.key

converting .env files to a secret #

Working with web applications .env is a common way to store credentials. Let’s look at how we can convert these to secrets.

kubectl create secret generic mysecret --from-env-file=.env -n thenamespace --dry-run=client -o yaml > mysecret.yaml

Now you have a secret that looks like this.

apiVersion: v1
data:
  foo: YmFy
kind: Secret
metadata:
  creationTimestamp: null
  name: mysecret
  namespace: thenamespace

Seal it up just like before.

kubeseal -f mysecret.yaml -w mysealedsecret.yaml

Using the secrets #

I typically use the secrets in the container spec.

containers:
  - name: myapp
    envFrom:
      - secretRef:
          name: mysecret
    # You can still have other env vars
    env:
      - name: foo
        value: bar

Sometimes I want to mount the secret as a volume.

containers:
  - name: myapp
    volumeMounts:
      - name: mysecret
        mountPath: /mysecret
volumes:
  - name: mysecret
    secret:
      secretName: mysecret

Image Pull Secrets #

I also need to use imagePullSecrets. Let’s walk through the whole process. Starting with the secret.

kubectl create secret docker-registry regcred --docker-server=myprivateregistry.example.com --docker-username=foo --docker-password=bar --dry-run=client -o yaml

Generates the following secret.

apiVersion: v1
data:
  .dockerconfigjson: eyJhdXRocyI6eyJteXByaXZhdGVyZWdpc3RyeS5leGFtcGxlLmNvbSI6eyJ1c2VybmFtZSI6ImZvbyIsInBhc3N3b3JkIjoiYmFyIiwiYXV0aCI6IlptOXZPbUpoY2c9PSJ9fX0=
kind: Secret
metadata:
  creationTimestamp: null
  name: regcred
type: kubernetes.io/dockerconfigjson

---

the secret

Now we we can seal that secret.

kubeseal -f regcred.yaml -w regcred-sealed.yaml

And that gives us the following sealed secret that we can deploy into our cluster.

---
apiVersion: bitnami.com/v1alpha1
kind: SealedSecret
metadata:
  creationTimestamp: null
  name: regcred
  namespace: default
spec:
  encryptedData:
    .dockerconfigjson: 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
  template:
    metadata:
      creationTimestamp: null
      name: regcred
      namespace: default
    type: kubernetes.io/dockerconfigjson

Now that we have our sealed registry secret, we can deploy it into our cluster.

kubectl apply -f regcred-sealed.yaml

Now we can use it to pull images from our private registry.

containers:
  imagePullSecrets:
    - name: regcred

Here is a full deployment example using all the secrets we have created.

          secret:
            secretName: mysecret
      imagePullSecrets:
        - name: regcred

Downside #

Now the main downside I see with kubeseal is that it does not provide a way to store your secrets in a way that you can access outside of your cluster. So you need to make sure that you have another solution in place to store your secrets so that you still have them if you ever were to take the cluster down or move from k8s to something else.

Overall the likelyhood of you loosing a production cluster is pretty low, so maybe it’s ok to just trust it depending on what the secrets are. Especially for things you control and can rotate anyways its fine.

nvim stupid gf bind

2023-12-28T10:04:57Z

So after months of fighting with gf not going to template files, I finally decided to put in some effort to make it work.

This was the dumbest keybind in my config, that I copied from someone else without understanding it.

What I am trying to do #

I have jinja templates in a directory called templates. I want to bind gf to open a template file, but it is trying to open a new file ./base.html

{% extends "base.html" %}
{% if request.state.user %}
    {% block title %}Fokais - {{ request.state.user.full_name }} {% endblock %}
{% else %}
    {% block title %}Fokais {% endblock %}
{% endif %}
{% block content %}
    {% if request.state.user %}
        <h1 id="title"
            class="inline-block mx-auto text-5xl font-black leading-loose
            text-transparent bg-clip-text bg-gradient-to-r from-red-600
            via-pink-500 to-yellow-400 ring-red-500 text-shadow-xl
            text-shadow-zinc-950 ring-5">
            {{ request.state.user.full_name }}
        </h1>
    {% endif %}
    {% include "me_partial.html" %}
{% endblock %}

What did not work #

I tried all sorts of changes to my path, but it still didn’t work.

vim.api.nvim_command("set path+=templates/**")

What I found #

after digging into my keymap I found that I had remaped gf to edit years ago. This works great if the file is in your current directory, and if it’s not it makes the file. This bind completely breaks vim’s ability to :find files and was a terrible keybind that I added probably from someone else years ago and have literally never used this feature. If gf opens an empty file I always close it and assume that vim failed to :find the file.

-- Allow gf to open non-existent files
set("", "gf", ":edit <cfile><CR>")

Yes, after that fix I still needed to adjust my path #

I ended up with the following in my options.lua.

-- look for jinja templates in the templates directory
vim.opt.path:append("templates/**")

cli auth

2023-12-17T20:09:03Z

Authentication from cli tools can be a bit of a bear, and I have to look it up every time. This is my reference guide for future me to remember how to easily do it.

I set up a fastapi server running on port 8000, it uses a basic auth with waylonwalker as the username and asdf as the password. The server follows along with what comes out of the docs. I have it setup to take basic auth, form username and password, or a bearer token for authentication.

curl #

Hiding Form input During htmx Request

2023-12-14T07:56:27Z

I am working on fokais.com’s signup page, and I want to hide the form input during an htmx request. I was seeing some issues where I was able to prevent spamming the submit button, but was still able to get one extra hit on it.

It also felt like nothing was happening while sending the email to the user for verification. Now I get the form to disappear and a spinner to show during the request.

html">HTML #

Let’s start off with the form. It uses htmx to submit a post request to the post_request route. Note that there is a spinner in the post_request with the htmx-indicator class.

The intent is to hide the spinner until the request is running, and hide all of the form input during the request.

<form

Yes this is styled using tailwindcss.

CSS #

Let’s take a look at how we achieve switching between only spinner an only form inputs using css.

.htmx-indicator {
  @apply hidden;
  opacity: 0;
  transition: opacity 500ms ease-in;
}
.htmx-request button,
.htmx-request input[type="submit"],
.htmx-request input,
.htmx-request label {
  @apply hidden;
}
.htmx-request .htmx-indicator {
  opacity: 1;
  @apply block;
}
.htmx-request.htmx-indicator {
  opacity: 1;
  @apply block;
}

Stripe Cancellations in FastAPI and SQLModel

2023-12-09T22:29:15Z

Today I am working on fokais.com, trying to get to a point where I can launch by workig through stripe integrations. This is my first time using stripe, so there has been quite a bit to learn, and I am probably building in more than I need to before launching, but I am learning, and not in a rush to launch.

I am building the fokais backent in python primarilyt with fastapi and sqlmodel on sqlite. My billing integration is going to be all Stripe.

Stripe Subscription Cancellations Docs #

Here is a link to the stripe docs for your refrence, especially if you want to see how to cancel subscriptions in other languages. They include code samples for many popular languages.

User Model #

This is the part of the user model that includes the cancel and reactivate methods. It pretty much follows the stripe guide.

class UserBase(SQLModel, table=False):  # type: ignore[call-arg]
    username: str = Field(unique=True)
    full_name: str
    email: str
    email_verified: bool = False
    disabled: bool = False
    signup_date: Optional[datetime] = Field(default_factory=datetime.utcnow)
    stripe_customer_id: Optional[str]

    def cancel_subscription(self):
        for subscription in self.active_subscriptions:
            stripe.Subscription.modify(
                subscription.id,
                cancel_at_period_end=True,
            )
        self.refresh()

    def reactivate_subscription(self):
        for subscription in self.active_subscriptions:
            stripe.Subscription.modify(
                subscription.id,
                cancel_at_period_end=False,
            )
        self.refresh()

Cancellations api #

Here is the cancellations api. I created an are you sure form that I can link to from the accounts page with a normal anchor tag. Note that I am doing a POST request to do the cancellation from a form. I want this to work for any user whether there is js or not. This is an operation that will change the users data, and I want to make sure that it avoids all browser and cdn caching. As a scrappy startup we are running light on infrastructure and are caching hard at the CDN to avoid excessive server hits.

Note

 I am doing a `POST` request to do the cancellation from a form.

@pricing_router.get("/cancel")
@pricing_router.get("/cancel/")
def get_cancel(
    request: Request,
    current_user: Annotated[User, Depends(get_current_user_if_logged_in)],
):
    return config.templates.TemplateResponse(
        "cancel.html",
        {
            "request": request,
            "prices": products.prices,
            "products": products.products,
            "current_user": current_user,
        },
    )


@pricing_router.post("/cancel")
@pricing_router.post("/cancel/")
def post_cancel(
    request: Request,
    current_user: Annotated[User, Depends(get_current_user_if_logged_in)],
):
    current_user.cancel_subscription()
    return HTMLResponse('<p id="cancel" hx-swap-oob="outerHTML">Your Subscription has been Cancelled</p>')

Reactivations #

Reactivating accounts looks just about the same as cancelling, only flippng True to False.


@pricing_router.get("/reactivate")
@pricing_router.get("/reactivate/")
def get_reactivate(
    request: Request,
    current_user: Annotated[User, Depends(get_current_user_if_logged_in)],
):
    return config.templates.TemplateResponse(
        "reactivate.html",
        {
            "request": request,
            "prices": products.prices,
            "products": products.products,
            "current_user": current_user,
        },
    )


@pricing_router.post("/reactivate")
@pricing_router.post("/reactivate/")
def post_reactivate(
    request: Request,
    current_user: Annotated[User, Depends(get_current_user_if_logged_in)],
):
    current_user.reactivate_subscription()
    return HTMLResponse('<p id="reactivate" hx-swap-oob="outerHTML">Your Subscription has been reactivated</p>')

Full User Model #

This is the full user model, completely subject to change in the future, but it includes the cancel and reactivate methods.

Still Loving Tailwind

2023-11-30T11:54:52Z

I’ve been using tailwind for a few months now and I can still say I’m loving it. I’ve been using it to create some rapid prototypes that may or may not ever become something, a document that is likely to go to print (a resume), and some quick dashboards.

I started using Tailwind a few month back #

A few months back in september of 2023 I made a case for tailwindcss. And have been using it on quite a few projects since.

values are well thought out
it’s really easy to use
classes that make sense
tree shakable

fokais.com #

I started working on fokais.com only a few weeks ago, It’s going to be a SAS to make blogging easier. I’ve started hosting some tools for this blog that I really like that I think I can turn into a service. It’s been fantastic to quickly pump out new pages with tailwind.

htmx">HTMX #

tailwind and htmx are a match made in heaven. They both really lean on Location of Behavior over Separation of concerns. They do really well at making small components that you can throw on and endpoint and stack into any page. With tailwind I just configure it to look at all my templates, and I can guarantee that the styles will be in app.css, and all I need to do is add classes to my component.

Heres a sample component for a user widget that will go on every page. It has everything it needs right in the template.

<div
  hx-swap-oob="outerHTML"
  id="user-header"
  class="absolute top-0 right-0 mt-8 mr-4"
>

<!--markata-attribution-->
  {% if current_user %}

  >
    <summary style="list-style-type: none">{{ current_user.username }}</summary>

<!--markata-attribution-->
    <div class="hidden group-hover:block my-4">

      <a
        class="mt-6 px-4 py-2 rounded bg-purple-950/5 ring-2 ring-cyan-500/30 text-cyan-500 font-bold"

        href="{{ url_for('get_logout') }}"
      >

        Logout
      </a>

internal apps #

I’ve built several interal apps, and tailwind has been really great for this. Its super quick to pop classes on components and get things to look decent quickly, or put some real polish into making them look nice.

My Website waylonwalker.com #

I’ve dropped my old decrepid css for some tailwind on my main site. My css was much smaller, but did not work quite as well on all devices, and most importantly was becoming a house of cards. Every time I fixed one thing several other things would fail. Colors were a bit muddy, and not as nicely configured as tailwind.

Most importantly was becoming a house of cards. Every time I fixed one thing several other things would fail.

One rough side of styling a blog in tailwind is that you don’t necessarily have control over granular details of how your pages get rendered without getting really deep into the markdown renderer, or writing your posts in html. It ends up looking a bit ugly, and is against the tailwind best practices, but it seems like the best way for a site like this.

@tailwind base;
@tailwind components;
@tailwind utilities;
@import "./highlight.css";

.social {
  @apply font-bold;
  @apply flex flex-row;
  @apply gap-4;
  @apply justify-center;
  @apply py-8;
}

#posts ul ul {
  @apply backdrop-blur-sm;
  @apply flex flex-col sm:grid grid-flow-row-dense;
  @apply gap-4;
  grid-template-columns: repeat(auto-fit, minmax(300px, 1fr));
  @apply p-4;
}

grid #

I’ve struggled to use grid on my projects, and I’ve tried a few different times with no real success or adoption, but started using it on my resume, to have a main middle column, with two outer full bleed columns where I can make some elements full bleed to the edge. tailwind made this easy, once done, I had an admonition that was beautiful full bleed with a touch of color.

jpillora-installer

2023-10-04T19:28:33Z

jpillora/installer is the install script generator I have been looking for. It downloads binaries for your machine from GitHub releases and unzips them for you. It grabs the latest release, so you can easily update them. I have tried scripting these installs in the past and struggled to consistently get the latest version for every package and unpack it correctly.

Also these pre-compiled binaries install rediculously fast compared to building them from source.

Check out some example links.

opening in a browser will show metadata

https://i.jpillora.com/serve

If you pass in script=true it will instead return the install script as it would by default through curl.

https://i.jpillora.com/serve?script=true

Use it to install neovim #

All you need to do to generate an install script is to pass in the GitHub repo slug with the org.

curl https://i.jpillora.com/neovim/neovim | bash

The shell script that it generates for neovim looks like this.

#!/bin/bash

how to host static content with fastapi

2023-10-04T08:32:58Z

I wanted to host some static files through fastapi. Typical use cases for this might be some static web content like html/css/js. It could also be images or some data that doesn’t need dynamically rendered.

From the Docs #

The docs cover how to host static files, and give this solution that is built into fastapi.

https://fastapi.tiangolo.com/tutorial/static-files/

from fastapi import FastAPI
from fastapi.staticfiles import StaticFiles

app = FastAPI()

app.mount("/static", StaticFiles(directory="static"), name="static")

Authenticated Static Files #

Thanks to #858.

OscartGiles posted this solution to add authentication to static files. I tried this out on my thoughts and it worked flawlessly.

import typing
from pathlib import Path
import secrets

from fastapi import FastAPI, Request, HTTPException, status
from fastapi.staticfiles import StaticFiles
from fastapi.security import HTTPBasic, HTTPBasicCredentials


PathLike = typing.Union[str, "os.PathLike[str]"]
app = FastAPI()
security = HTTPBasic()


async def verify_username(request: Request) -> HTTPBasicCredentials:

    credentials = await security(request)

    correct_username = secrets.compare_digest(credentials.username, "user")
    correct_password = secrets.compare_digest(credentials.password, "password")
    if not (correct_username and correct_password):
        raise HTTPException(
            status_code=status.HTTP_401_UNAUTHORIZED,
            detail="Incorrect email or password",
            headers={"WWW-Authenticate": "Basic"},
        )
    return credentials.username


class AuthStaticFiles(StaticFiles):
    def __init__(self, *args, **kwargs) -> None:

        super().__init__(*args, **kwargs)

    async def __call__(self, scope, receive, send) -> None:

        assert scope["type"] == "http"

        request = Request(scope, receive)
        await verify_username(request)
        await super().__call__(scope, receive, send)


app.mount(
    "/static",
    AuthStaticFiles(directory=Path(__file__).parent / "static"),
    name="static",
)

If you want both then, all you have to do is mount AuthStaticFiles to a different route. Now you can have private, or paid content behind /restricted.

app.mount("/static", StaticFiles(directory="static"), name="static")
app.mount(
    "/restricted",
    AuthStaticFiles(directory=Path(__file__).parent / "restricted"),
    name="restricted"
)

Set up minio bucket entrypoint

2023-10-01T20:11:51Z

I recently se tup minio object storage in my homelab for litestream sqlite backups. The litestream quickstart made it easy to get everything up and running on localhost, but I hit a wall when dns was involved to pull it from a different machine.

Here is what I got to work #

First I had to configure the Key ID and Secret Access Key generated in the minio ui.

❯ aws configure
AWS Access Key ID [****************VZnD]:
AWS Secret Access Key [****************xAm8]:
Default region name [us-east-1]:
Default output format [None]:

Then set the the s3 signature_version to s3v4.

aws configure set default.s3.signature_version s3v4

Now when I have minio running on https://my-minio-endpoint.com I can use the aws cli to access the bucket.

Note that https://my-minio-endpoint.com resolves to the bucket endpoint (default 9000) not the ui (default 9001).

aws --endpoint-url https://my-minio-endpoint.com s3 ls my_bucket

Now Configuring Litestream #

Litestream also accepts the endpoint argument via config. I could not get it to work just with the ui.

Note the aws configure step above is not required for litestream, only the aws cli.

dbs:
  - path: /path/to/database.db
    replicas:
      - url: s3://my_bucket/
        endpoint: https://my-minio-endpoint.com
        region: us-east-1
        access-key-id: ****************VZnD
        secret-access-key: ************************************xAm8

Now run a litestream replication.

litestream replicate -config litestream.yml
# or put the config in /etc/litestream.yml and just run replicate
litestream replicate

Setup Tailwind for Jinja

2023-09-17T17:10:32Z

I’ve recently given tailwindcss a second chance and am really liking it. Here is how I set it up for my python based projects.

https://waylonwalker.com/a-case-for-tailwindcss

Installation #

npm is used to install the cli that you will need to configure and compile tailwindcss.

npm install -g tailwindcss-cli

Setup #

You will need to create a tailwind.config.js file, to get this you can use the cli.

npx tailwindcss init

Using tailwind with jinja templates #

To set up tailwind to work with jinja templates you will need to point the tailwind config content to your jinja templates directory.

module.exports = {
  content: ["templates/**/*.html"],
};

Setting up the base styles #

I like to use the @tailwind base;, to do this I set up an input.css file.

@tailwind base;
@tailwind components;
@tailwind utilities;

Compiling #

Now that it’s all setup you can run the tailwindcss command. You will get an output.css with base tailwind plus any of the classes that you used.

tailwindcss -i ./input.css -o ./output.css --watch

Python scandir ignores hidden directories

2023-06-17T20:19:59Z

The next version of markata will be around a full second faster at building it’s docs, that’s a 30% bump in performance at the current state. This performance will come when virtual environments are stored in the same directory as the source code.

What happened?? #

I was looking through my profiler for some unexpected performance hits, and noticed that the docs plugin was taking nearly a full second (sometimes more), just to run glob.

    |  |- 1.068 glob  markata/plugins/docs.py:40
    |  |  |- 0.838 <listcomp>  markata/plugins/docs.py:82
    |  |  |  `- 0.817 PathSpec.match_file  pathspec/pathspec.py:165
    |  |  |        [14 frames hidden]  pathspec, <built-in>, <string>

Python scandir ignores hidden directories #

I started looking for different solutions and what I found was that I was hitting pathspec with way more files than I needed to.

len(list(Path().glob("**/*.py")))
# 6444
len([Path(f) for f in glob.glob("**/*.py", recursive=True)])
# 110

After digging into the docs I found that glob.glob uses os.scandir which ignores ‘.’ and ‘..’ directories while Path.glob does not.

https://docs.python.org/3/library/os.html#os.scandir

results? #

Now glob.py from the docs plugin does not even show up in the profiler.

I opened up ipython and saw the following results. For some reason as I hit docs.glob it was only hitting 488 ms from ipython, but it was still a massive improvement over the original.

%timeit docs.glob(m)
# 488 ms ± 3.05 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

%timeit docs.glob(m)
# 9.37 ms ± 90.9 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

setting up paru | installing from the AUR for the first time

2023-05-27T20:22:42Z

AUR.">paru is an aur helper that allows you to use a package manager to install packages from the aur.

What’s the Aur #

The Aur is a set of community managed packages that can be installed on arch based distros.

Why a helper? #

paru just makes it easy, no clone and run makepkg. You can do everything paru can do using the built in pacman installer.

Manual Install from the Aur #

You will need to manually instal pacman from the aur in order to get started.

sudo pacman -S --needed base-devel
git clone https://aur.archlinux.org/paru.git
cd paru
makepkg -si

Installing packages with paru #

Once setup you are ready to install packages from the AUR just like the core repos.

# you can update your system using paru
paru -Syu

# you can install packages from the AUR
paru -S tailscale
paru -S prismlauncher

# even core repo packages can be installed
paru -S docker

Paru in Docker #

Here is a snippet from my devtainer dockerfile. Where I use paru to install packages from the AUR inside of a dockerfile.

FROM archlinux

RUN echo '[multilib]' >> /etc/pacman.conf && \
    echo 'Include = /etc/pacman.d/mirrorlist' >> /etc/pacman.conf && \
    pacman --noconfirm -Syyu && \
    pacman --noconfirm -S base-devel git && \
    groupadd --gid 1000 devtainer && \
    useradd --uid 1000 --gid 1000 -m -r -s /bin/bash devtainer && \
    passwd -d devtainer && \
    echo 'devtainer ALL=(ALL) ALL' > /etc/sudoers.d/devtainer && \
    mkdir -p /home/devtainer/.gnupg && \
    echo 'standard-resolver' > /home/devtainer/.gnupg/dirmngr.conf && \
    chown -R devtainer:devtainer /home/devtainer && \
    mkdir /build && \
    chown -R devtainer:devtainer /build && \
    cd /build && \
    sudo -u devtainer git clone --depth 1 https://aur.archlinux.org/paru.git && \
    cd paru && \
    sudo -u devtainer makepkg --noconfirm -si && \
    sed -i 's/#RemoveMake/RemoveMake/g' /etc/paru.conf && \
    pacman -Qtdq | xargs -r pacman --noconfirm -Rcns && \
    rm -rf /home/devtainer/.cache && \
    rm -rf /build

USER devtainer
RUN sudo -u devtainer paru --noconfirm --skipreview --useask -S \
    bat \
    cargo \
    direnv \
    dua-cli \
    dust \
    fd

Final Thoughts #

There are other options out there, paru seemed to be the most supported at the time I started using arch and there has been no other reason for me to change it. It’s treated me well for nearly a year now.

Releasing a New Version of Your Python Package Just Got Easier

2023-01-23T10:52:19Z

Quickly and easily create new versions of your Python package with the gh release command. Get the version number, changelog, and

Releasing a new version of your Python package can be a daunting task. You need to make sure that all the necessary files are included, and that the version number is correct. But now, with the help of the gh release command, you can make the process much smoother.

The gh release command allows you to quickly and easily create a new version of your Python package. All you need to do is provide the version number, the changelog, and the distribution files. For example, if you wanted to create a new version of your package with the version number v1.2.3, you could use the following command:

gh release create v1.2.3 -F CHANGELOG.md dist/*.whl dist/*.tar.gz

This command will create a new version of your package with the specified version number, and include the changelog and the distribution files. It’s a great way to make sure that all the necessary files are included in the release, and that the version number is correct.

The gh release command is a great tool for quickly and easily creating new versions of your Python package. With just a few simple commands, you can make sure that all the necessary files are included, and that the version number is correct. So if you’re looking for an easy way to release a new version of your Python package, give the gh release command a try.

Arch Linux Randomly Rejecting Passwords

2023-01-19T07:46:31Z

Fix Arch Linux randomly rejecting passwords with one command. Try ‘faillock –user $USER’ to reset login counter and regain access. Quick solution for a smooth computing"

If you’re an Arch Linux user, you may have experienced a frustrating issue where your password is randomly not being accepted by the system. This can be a major inconvenience and can cause a lot of frustration, especially if it happens frequently.

The good news is that there is a simple fix for this issue. The following bash code can be used to fix the problem:

bash faillock --user $USER

This command is used to reset the failed login count for the current user. By running this command, you will be able to reset the system’s login counter and regain access to your account.

It’s important to note that this command should only be used as a temporary solution. If you find yourself frequently having to run this command, it’s likely that there is a deeper issue with your system that needs to be addressed.

In any case, if you’re experiencing problems with your Arch Linux system not accepting your password, give the above command a try and see if it resolves the issue for you.

dash e your github docker actions

2022-12-07T13:09:37Z

Give github actions the -e flag in the shebang #! so they fail on any one command failure. Otherwise each line will set the exit status, but only the last one will be passed to ci.

#!/bin/bash -e

What is -e #

The -e flag to the bash command allows your script to exit immediately if any command within the script returns a non-zero exit status. This can be useful for ensuring that your script exits with an error if any of the commands it runs fail, which can help you identify and debug issues in your script. For example, if you have a script that runs several commands and one of those commands fails, the script will continue running without the -e flag, but will exit immediately if the -e flag is present. This can make it easier to troubleshoot your script and ensure that it runs correctly.

Solution for Windows #

In windows the solution is not quite as simple. You can define a function in a Windows batch script that wraps an if statement to check the exit status of a command and handle any errors that may have occurred. Here is an example of how you might define a function called “check_error” that does this:

:check_error
if errorlevel 1 (
  echo An error occurred!
  exit /b 1
)

To use this function in your script, you would simply call it after running a command, like this:

some_command
call :check_error

This would run the “some_command” and then call the “check_error” function to check the exit status and handle any errors that may have occurred. This approach allows you to reuse the error-checking logic in your script, which can make it easier to write and maintain.

ssh copy id

tmux push/pull panes

2022-12-04T13:25:54Z

Moving panes between tmux sessions is something that makes tmux a very flexible and powerful tool. I don’t need this feature very often, but it comes in clutch when you need it.

Pull a pane from any other session #

Using choose-window I was able to come up with a way to select any pane withing any other session and join it into my current session.

# Choose a pane to join in horizontally
bind f choose-window -Z 'join-pane -h -s "%%"'

Push/Pull from scratch #

I’ve long had this one in my tmux config, I always have a “scratch” session that I’m running, I often use for looking at things like k9s accross repos within a popup.

This use case puts a pane into the scratch session, then pulls it back out. I will use this to move a pane between sessions in the rare cases I need to do this.

# push the active pane into the scratch session horizonally
bind -n M-f join-pane -ht scratch
# pull the last active pane from the scratch session horizonally into this session
bind -n M-F join-pane -hs scratch

nvim navic

2022-10-27T20:13:20Z

With the latest release of version of nvim 0.8.0 we get access to a new winbar feature. One thing I have long wanted somewhere in my nvim is navigation for pairing partners or anyone watching can keep track of where I am. As the driver it’s easy to keep track of the file/function you are in. But when you make big jumps in a few keystrokes it can be quite disorienting to anyone watching, and having this feedback to look at is very helpful.

winbar #

nvim exposes the winbar api in lua, and you can send any text to the winbar as follows.

vim.o.winbar = "here"

You can try it for yourself right from the nvim command line.

:lua vim.o.winbar = "here"

Now you will notice one line above your file with the word here at the very beginning.

Clearing the winbar #

If you want to clear it out, you can just set it to an empty string or nil.

:lua vim.o.winbar = ""
:lua vim.o.winbar = nil

Setting up nvim-navic #

You will need to install nvim-navic if you want to use it. I added it to my plugins using Plug as follows.

call plug#begin('~/.local/share/nvim/plugged')
Plug 'SmiteshP/nvim-navic'
call plug#end()

Note! nvim-navic does require the use of the nvim lsp, so if you are not using it then maybe this won’t work for you.

I created an on_attach function long ago, cause that’s what Teej told me to do. Now I am glad I did, because it made this change super easy.

local function on_attach(client, bufnr)
    if client.server_capabilities.documentSymbolProvider then
        navic.attach(client, bufnr)
    end
end

Then you need to use that on_attach function on all of the lsp’s that you want navic to work on.

Then in a lua file you need to setup the winbar, for now I put this in my lsp-config settings file, but eventually I want to move my settings to lua and put it there.

vim.o.winbar = " %{%v:lua.vim.fn.expand('%F')%}  %{%v:lua.require'nvim-navic'.get_location()%}"

What my winbar looks like #

What I have right now is everything someone who is watching would need to know to navigate to the same place that I am in the project.

pipx textual devtools

2022-10-24T08:16:33Z

I really like having global cli command installed with pipx. Since textual 0.2.x (the css release) is out I want to be able to pop into textual devtools easily from anywhere.

Pipx Install #

You can pipx install textual.

pipx install textual

But if you try to run any textual cli commands you will run into a ModuleNotFoundError, because you need to install the optional dev dependencies.

Traceback (most recent call last):
  File "/home/u_walkews/.local/bin/textual", line 5, in <module>
    from textual.cli.cli import run
  File "/home/u_walkews/.local/pipx/venvs/textual/lib/python3.10/site-packages/textual/cli/cli.py", line 4, in <module>
    import click
ModuleNotFoundError: No module named 'click'

Pipx Inject #

In order to install optional dependencies with pipx you need to first install the library, then inject in the optional dependencies using the square bracket syntax.

pipx install textual
pipx inject textual 'textual[dev]'

textual app devtools

2022-10-24T07:42:48Z

I am working through the textual tutorial, and I want to put it in a proper cli that I can pip install and run the command without textual run --dev app.py. This is a fine pattern, but I also want this to work when I don’t have a file to run.

pyproject.toml entrypoints #

I set up a new project running hatch new, and added the following entrypoint, giving me a tutorial cli command to run.

...

[project.scripts]
tutorial = 'textual_tutorial.tui:tui'

https://waylonwalker.com/hatch-new-cli/

setup.py entrypoints #

If you are using setup.py, you can set up entrypoints in the setup command.

from setuptools import setup

setup(
    ...
    entry_points={
        "console_scripts": ["tutorial = textual_tutorial.tui:tui"],
    },
    ...
)

https://waylonwalker.com/minimal-python-package/

tui.py #

adding features

Now to get devtools through a cli without running through textual run --dev. I pulled open the textual cli source code, and this is what it does at the time of writing.

Note: I used sys.argv as a way to implement a --dev quickly tutorial. For a real project, I’d setup argparse, click, or typer. typer is my go to these days, unless I am really trying to limit dependencies, then the standard library argparse might be what I go with.

def tui():

    from textual.features import parse_features
    import os
    import sys

    dev = "--dev" in sys.argv # this works, but putting it behind argparse, click, or typer would be much better

    features = set(parse_features(os.environ.get("TEXTUAL", "")))
    if dev:
        features.add("debug")
        features.add("devtools")

    os.environ["TEXTUAL"] = ",".join(sorted(features))
    app = StopwatchApp()
    app.run()


if __name__ == "__main__":
    tui()

Other Flags??? #

If you look at the source, there is one other flag for headless mode.

FEATURES: Final = {"devtools", "debug", "headless"}

Run it #

Here it is running with tutorial --dev on the left, and textual console on the right.

obs virtual camera on boot

2022-10-18T08:34:25Z

For far too long I have had to fidget with v4l2oloopback after reboot. I’ve had this happen on ubuntu 18.04, 22.04, and arch.

After a reboot the start virtual camera button won’t work, It appears and is clickable, but never turns on. Until I run this command.

sudo modprobe v4l2loopback video_nr=10 card_label="OBS Video Source" exclusive_caps=1

Today I learned that you can turn on kernel modules through some files in /etc/modules...

This is what I did to my arch system to get it to work right after boot.

echo "v4l2loopback" | sudo tee /etc/modules-load.d/v4l2loopback.conf
echo "options v4l2loopback video_nr=10 card_label=\"OBS Video Source\" exclusive_caps=1" | sudo tee /etc/modprobe.d/v4l2loopback.conf

localstack status permission

2022-10-17T08:55:26Z

I ran into an issue where I was unable to ask localstack for its status. I would run the command and it would tell me that it didn’t have permission to read files from my own home directory. Let’s fix it

The issue #

I would run this to ask for the status.

localstack status

And get this error

PermissionError: [Errno 13] Permission denied: '/home/waylon/.cache/localstack/image_metadata'

What happened #

It dawned on me that the first time I ran localstack was straight docker, not the python cli. When docker runs it typically runs as root unless the Dockerfile sets up a user and group for it.

How to fix it #

If you have sudo access to the machine you are on you can recursively change ownership to your user and group. I chose to just give myself ownership of my whole ~/.cache directory you could choose a deeper directory if you want. I feel pretty safe giving myself ownership to my own cache directory on my own machine.

whoami
# waylon

chown -R waylon:waylon ~/.cache

Now it’s working #

Running localstack status now gives me a nice status message rather than an error.

markata-gh #

The first example that you can use right now is markata-gh. It will render repos by GitHub topic and user using the gh cli, which is available in github actions!

Get it with a pip install

pip install markata-gh

Use it with some jinja in your markdown.

## Markata plugins

It uses the logged in uer by default.

{% gh_repo_list_topic "markata" %}

You can more explicitly grab your username, and a topic.
{% gh_repo_list_topic "waylonwalker", "personal-website" %}

How is this achieved #

The jinja extension details are for another post, but this is how markata-gh exposes itslef as a jinja extension.

class GhRepoListTopic(Extension):
    tags = {"gh_repo_list_topic"}

    def __init__(self, environment):
        super().__init__(environment)

    def parse(self, parser):
        line_number = next(parser.stream).lineno
        try:
            args = parser.parse_tuple().items
        except AttributeError:
            raise AttributeError(
                "Invalid Syntax gh_repo_list_topic expects <username>, or <username>,<topic> both must have the comma"
            )

        return nodes.CallBlock(self.call_method("run", args), [], [], "").set_lineno(
            line_number
        )

    def run(self, username=None, topic=None, caller=None):
        "get's markdown to inject into post"
        return repo_md(username=username, topic=topic)

Entrypoints #

Then markata-gh exposes itself as an extension through entrypoints.

Creating entrypoints in pyproject.toml #

If your project is using pyproject.toml for packaging you can setup an entrypoint as follows.

[project.entry-points."markata.jinja_md"]
markta_gh = "markata_gh.repo_list:GhRepoListTopic"

Creating entrypoints in setup.py #

If your project is using setup.py for packaging you can setup an entrypoint as follows.

setup(
    ...
    entry_points={
        "markata.jinja_md": ["markta_gh" = "markata_gh.repo_list:GhRepoListTopic"]
    },
    ...
)

Getting Started with Django REST framework

2022-10-09T15:57:37Z

In my adventure to learn django, I want to be able to setup REST api’s to feed into dynamic front end sites. Potentially sites running react under the hood.

Install #

To get started lets open up a todo app that I created with django-admin startproject todo.

pip install djangorestframework

Install APP #

Now we need to declare rest_framwork as an INSTALLED_APP.

INSTALLED_APPS = [
    ...
    "rest_framework",
    ...
]

create the api app #

Next I will create all the files that I need to get the api running.

mkdir api
touch api/__init__.py api/serializers.py api/urls.py api/views.py

base/models.py #

I already have the following model from last time I was playing with django. It will suffice as it is not the focus of what I am learning for now.

Note the name of the model class is singular, this is becuase django will automatically pluralize it in places like the admin panel, and you would end up with Itemss.

from django.db import models

# Create your models here.

class Item(models.Model):
    name = models.CharField(max_length=200)
    created = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return f"{self.priority} {self.name}"

Next I will make some dummy data to be able to return. I popped open ipython and made a few records.

from base.models import Item

Item.objects.create(name='first')
Item.objects.create(name='second')
Item.objects.create(name='third')

api/serializers.py #

Next we need to set up a serializer to seriaze and de-serialize data between our model and json. You can specify each field individually or all of them by passing in __all__.

from rest_framework import serializers

from base.models import Item


class ItemSerializer(serializers.ModelSerializer):
    class Meta:
        model = Item
        fields = '__all__'

api/views.py #

Now we need a view leveraging the djangorestframework. The serializer we just created will be used to serialize all of the rows into a list of objects that Response can handle.

Note: to return a collection of model objects we need to set many to True

from rest_framework.decorators import api_view
from rest_framework.response import Response

from base.models import Item

from .serializers import ItemSerializer


@api_view(["GET"])
def get_data(request):
    items = Item.objects.all()
    serializer = ItemSerializer(items, many=True)
    return Response(serializer.data)

@api_view(['POST'])
def add_item(request):
    serializer = ItemSerializer(data = request.data)
    if serializer.is_valid():
        serializer.save()
    return Response()

api/urls.py #

Now we need to setup routing to access the views through an url.

from django.urls import path

from . import views

urlpatterns = [
        path('', views.get_data),
        path('add/', views.add_item),
        ]

todo/urls.py #

Then we need to include these urls from our api in the urls specified by settings.ROOT_URLCONf

from django.urls import path

urlpatterns = [
    ...
    path("api/", include("api.urls")),
]

Run it #

python manage.py runserver

Running the developement server and going to localhost:8000/api we can see the full list of items in th api.

Markata now uses hatch

2022-10-08T07:25:10Z

Markata now uses hatch as its build backend, and version bumping tool. setup.py, and setup.cfg are completely gone.

0.5.0 is big #

Markata 0.5.0 is now out, and it’s huge. Even though it’s the backend of this blog I don’t actually have that many posts directly about it. I’ve used it a bit for blog fuel in generic ways, like talking about pluggy and diskcache, but very little have I even mentioned it.

Over the last month I made a big push to get 0.5.0 out, which adds a whole bunch of new configurability to markata.

Here’s the changelog entry.

Moved to PEP 517 build #59 0.5.0.dev1

My Personal Simple CI/CD #

Before cutting all of my personal projects over to hatch. The first thing I did was to setup a solid github action, hatch-actionthat I can resue.

It automatically bumps versions, using pre-releases on all branches other than main, with special branches for bumping major, minor, patch, dev, alha, beta, and dev.

hatch new –init #

To convert the project over to hatch, and get rid of setup.py/setup.cfg, I ran hatch new --init. This automatically grabs all the metadata for the project and makes a pyproject.toml that has most of what I need.

hatch new --init

I then manually moved over my isort config, put flake8 config into .flake8, and dropped setup.cfg.

lint-test #

Part of my hatch-action is to run a before-command, for markata, this runs all of my linting and testing in one hatch script called lint-test. If this fails CI will fail and I can read the report in the logs, make a fix and re-publish.

[tool.hatch.envs.default.scripts]
cov = "pytest --cov-report=term-missing --cov-config=pyproject.toml --cov=markata --cov=tests"
no-cov = "cov --no-cov"
lint = "flake8 markata"
format = "black --check markata"
sort-imports = "isort markata"
build-docs = "markata build"
lint-test = [
 "lint",
 "format",
 "seed-isort-config",
 "sort-imports",
 "cov",
]
test-lint = "lint-test"

Typical branching workflow #

with automatic versioning

My typical workflow is to work on features in their own branch where they do not automatically version or publish, they keep the same version they were branched off of. Then I do a pr to develop, which will do a minor,dev bump and publish a pre-relese to pypi.

# starting with version 0.0.0
Feature1 -- │
Feature2 -- ├── dev 0.1.0.dev1,2,3 ── main 0.1.0
Feature3 -- │

I will let several features collect in develop before cutting a full relese over to main. This gives me time to make sure the solution is what makes the most sense, I try to use it in a few projects, and generally its edges show, and another pr is warranted to make the feature useful for more use cases. After running and using these new releases in a few projects, I am confident that its ready and release to main.

managing prs #

Doing PR’s with gh, probably deserves its own post but here are some helpful commands.

gh pr create --base develop --fill
gh pr edit
gh pr diff | dunk
gh pr merge -ds

Building and publishing #

hatch makes building and publishing pretty straightforward. It’s one command inside my hatch-action to build and one to publish. On each project that uses my hatch-action I only need to give it a token that I get from PyPi.

env:
  HATCH_INDEX_USER: __token__
  HATCH_INDEX_AUTH: ${{ secrets.pypi_password }}

Full set of changes #

django create superuser

2022-09-26T07:14:04Z

My next step into django made me realize that I do not have access to the admin panel, turns out that I need to create a cuper user first.

Run Migrations #

Right away when trying to setup the superuser I ran into this issue

django.db.utils.OperationalError: no such table: auth_user

Back to the tutorial tells me that I need to run migrations to setup some tables for the INSTALLED_APPS, django.contrib.admin being one of them.

python manage.py migrate

yes I am still running remote on from my chromebook.

python manage.py createsuperuser

The super user has been created.

CSRF FAILURE #

My next issue trying to run off of a separate domain was a cross site request forgery error.

Since this is a valid domain that we are hosting the app from we need to tell Django that this is safe. We can do this again in the settings.py, but this time the variable we need is not there out of the box and we need to add it.

CSRF_TRUSTED_ORIGINS = ['https://localhost.waylonwalker.com']

I made it!! #

And we are in, and welcomed for the first time with this django admin panel.

Remote Hosting #

You might find these settings helpful as well if you are trying to run your site on a remote host like aws, digital ocean, linode, or any sort of cloud providor. I had it running in my home lab while I was out of the house and ssh’d in over with a chromebook.

django disallowed host

2022-09-26T06:15:24Z

I am continuing my journey into django, but today I am not at my workstation. I am ssh’d in remotely from a chromebook. I am fully outside of my network, so I can’t access it by localhost, or it’s ip. I do have cloudflared tunnel installed and dns setup to a localhost.waylonwalker.com.

Settings #

I found this in settings.py and yolo, it worked first try. I am in from my remote location, and even have auth taken care of thanks to cloudflare. I am really hoping to learn how to setup my own auth with django as this is one of the things that I could really use in my toolbelt.

ALLOWED_HOSTS = ['localhost.waylonwalker.com']

Trying out django

2022-09-25T18:47:54Z

I have no experience in django, and in my exploration to become a better python developer I am dipping my toe into one of the most polished and widely used web frameworks Django to so that I can better understand it and become a better python developer.

If you found this at all helpful make sure you check out the django tutorial

install django #

The first thing I need to do is render out a template to start the project. For this I need the django-admin cli. To get this I am going the route of pipx it will be installed globally on my system in it’s own virtual environment that I don’t have to manage. This will be useful only for using startproject as far as I know.

pipx install django
django-admin startproject try_django
cd try_django

Make a venv #

Once I have the project I need a venv for all of django and all of my dependencies I might need for the project. I have really been diggin hatch lately, and it has a one line “make a virtual environment and manage it for me” command.

hatch shell

If hatch is a bit bleeding edge for you, or it has died out by the time you read this. The ol trusty venv will likely stand the test of time, this is what I would use for that.

python -m .venv --prmpt `basename $PWD`
. ./.venv/bin/activate

Start the webserver #

Next up we need to start the webserver to start seeing that development content. The first thing I did was run it as stated in the tutorial and find it clashed with a currently running web server port.

python manage.py runserver

I jumped over to that tmux session, killed the process and I was up and running.

What’s running #

The default django hello world looks well designed. You are first presented with this page.

Next #

I opened up the urls.py to discover that the only configured url was at /admin. I tried to log in as admin, but was unable to as I have not yet created a superuser. Next time I play with django that is what I will explore.

how to escape variables in jinja templates

2022-09-24T15:18:50Z

While updating my site to use Markata’s new configurable head I ran into some escaping issues. Things like single quotes would cause jinja to fail as it was closing quotes that it shouldnt have.

Jinja Escaping Strings #

Jinja comes with a handy utility for escaping strings. I definitly tried to over-complicate this before realizing. You can just pipe your variables into e to escape them. This has worked pretty flawless at solving some jinja issues for me.

<p>
{{ title|e }}
</p>

Creating meta tags in Markata #

The issue I ran into was when trying to setup meta tags with the new configurable head, some of my titles have single quotes in them. This is what I put in my markata.toml to create some meta tags.

[[markata.head.meta]]
name = "og:title"
content = "{{ title }}"

Using my article titles like this ended up causing this syntax error when not escaped.

SyntaxError: invalid syntax. Perhaps you forgot a comma?
Exception ignored in: <function Forward.__del__ at 0x7fa9807192d0>
Traceback (most recent call last):
    ...
TypeError: 'NoneType' object is not callable

jinja2 escape #

After making a complicated system of using html.escape I realized that jinja included escaping out of the box so I updated my markata.toml to include the escaping, and it all just worked!.

[[markata.head.meta]]
name = "og:title"
content = "{{ title|e }}"

I've made my ipython config too complicated, let's fix it.

2022-09-20T15:40:31Z

When I am developing python code I often have a repl open alongside of it running snippets ofcode as I go. Ipython is my repl of choice, and I hace tricked it out the best I can and I really like it. The problem I recently discovered is that I have way overcomplicated it.

What Have I done?? #

So in the past the way I have setup a few extensions for myself is to add something like this to my ~/.ipython/profile_default/startup directory. It sets up some things like rich highlighting or in this example automatic imports. I even went as far as installing some of these in the case I didn’t have them installed.

import subprocess

from IPython import get_ipython
from IPython.core.error import UsageError

ipython = get_ipython()

try:
    ipython.run_line_magic("load_ext pyflyby", "inline")
except UsageError:
    print("installing pyflyby")
    subprocess.Popen(
        ["pip", "install", "pyflyby"],
        stdout=subprocess.DEVNULL,
        stderr=subprocess.DEVNULL,
    ).wait()
    ipython.run_line_magic("load_ext pyflyby", "inline")
    print("installing isort")
    subprocess.Popen(
        ["pip", "install", "isort"],
        stdout=subprocess.DEVNULL,
        stderr=subprocess.DEVNULL,
    )

What I missed? #

I missed the fact that some of these tools like pyflyby and rich already have an ipython extension maintained by the library that just works. It’s less complicated and more robust to future changes in the library. If anything ever changes with these I will not have to worry about which version is installed, the extension will just take care of itself.

How to activate these. #

The reccomended way is to add them to your ~/.ipython/profile_default/ipython_config.py

c.InteractiveShellApp.extensions.append('rich')
c.InteractiveShellApp.extensions.append('markata')
c.InteractiveShellApp.extensions.append('pyflyby')

The issue that I found with this is that you can end up with a sea of errors flooding your terminal. Personally I will know immediately if ipython is working right or not and typically have scriped venv installs so I have everything I need, so If I don’t have everything it’s probably for a reason and I don’t need an error message lighting up.

My way around this was to test if the module was importable and if it had a load_ipython_extension attribute before appending it as an extension.

def activate_extension(extension):
    try:
        mod = importlib.import_module(extension)
        getattr(mod, "load_ipython_extension")
        c.InteractiveShellApp.extensions.append(extension)
    except ModuleNotFoundError:
        "extension is not installed"
    except AttributeError:
        "extension does not have a 'load_ipython_extension' function"


extensions = ["rich", "markata", "pyflyby"]
for extension in extensions:
    activate_extension(extension)

My Change #

If you want to see what I did to my config see this commit.

markata extend in configuration

2022-09-11T20:25:45Z

A long needed feature of markata has been the ability to really configure out templates with configuration rather. It’s been long that you needed that if you really want to change the style, meta tags, or anything in the head you needed to write a plugin or eject out of the template and use your own.

Adding some Head #

Now you can add some extra style to your site with the existing built-in template.

[[markata.head]]
text = """
<style>
img {
  width: 100%;
  height: auto;
}
ul {
  display: flex;
  flex-wrap: wrap;
}
</style>
"""

You can have more than one Head #

Each text entry in markata.head just gets appended raw into the head.

[[markata.head]]
text = """
<style>
img {
  width: 100%;
  height: auto;
}
ul {
  display: flex;
  flex-wrap: wrap;
}
</style>
"""

[[markata.head]]
text = """
<script>
console.log('hey there')
</script
"""

Still need more? #

If this does not take you far enough yet, you can still eject out and use your own template pretty easy. If you are going for a full custom site it’s likely that this will be the workflow for awhile. Markata should only get better and make this required less often as it matures.

[markata]
post_template = "pages/templates/post_template.html"

Once you have this in your markata.toml you can put whatever you want in your own template.

Create a new Python Project with the Hatch Cli

2022-09-02T07:54:03Z

I’m really getting into using hatch as my go to build system, and I am really liking it so far. I am slowly finding new things that just work really well. hatch new is one of those things that I didn’t realize I needed until I had it.

creating new versions created by myself with stable diffusion

❯ pipx run hatch new --help
Usage: hatch new [OPTIONS] [NAME] [LOCATION]

  Create or initialize a project.

Options:
  -i, --interactive  Interactively choose details about the project
  --cli              Give the project a command line interface
  --init             Initialize an existing project
  -h, --help         Show this message and exit.

Note! I am running all of these commands with pipx. I like to use pipx for all of my system level cli applications. To emphasis this point in the article I am going to use pipx run hatch, but you can pipx install hatch then just run hatch from there.

Interacively create a new project #

Running hatch new -i will ask let you interactivly choose details about the project, such as the project’s name.

pipx run hatch new -i

After running and naming the project Hatch New we end up with the following filetree.

❯ tree .
.
├── hatch_new
│   ├── __about__.py
│   └── __init__.py
├── LICENSE.txt
├── pyproject.toml
├── README.md
└── tests
    └── __init__.py

Non-Interative #

You can also fill in the project name ahead of time, and it will run without any questions.

❯ pipx run hatch new "Another Project"
another-project
├── another_project
│   ├── __about__.py
│   └── __init__.py
├── tests
│   └── __init__.py
├── LICENSE.txt
├── README.md
└── pyproject.toml

Note! all of these examples will create a project directory within your current working directory.

–init #

existing project

hatch new has an --init flag in order to initialize a new hatch pyproject.toml in an existing project. This feels like it would be useful if you are converting a project to hatch, or if like me you sometimes start making something before you realize it’s something that you want to package. Honestly this doesn’t happen too much anymore I package most things, and I hope hatch new completely breaks this habbit of mine.

Let’s say I have the following existing project.

❯ tree
.
└── hatch_init
    └── __init__.py

1 directory, 1 file

I can setup packaging with hatch by running.

pipx run hatch new --init

The pyproject.toml that comes out is pretty similar to the one that comes out of the normal hatch new, but without any other files.

Note that you will need to setup a __about__.py yourself for the dynamic versioning that it has setup for you.

cli #

hatch new does not stop there, it also has a --cli flag to give you a cli out of the box as well.

sneak peek #

I’ll dive more into environments and the run command later, but we can run the cli pretty damn quick with two commands. In under 5s I was able to run this cli that it created. This is a pretty incredible startup time.

Versioning Python Projects with Hatch

2022-09-01T13:19:22Z

Hatch has an amazing versioning cli for python packages that just works. It takes very little config to get going and you can start bumping versions without worry.

creating new versions created by myself with stable diffusion

project layout #

For trying out the hatch version cli let’s make a simple project with the terrible name pkg.

❯ tree .
.
├── pkg
│   ├── __about__.py
│   └── __init__.py
├── pyproject.toml
└── README.md

1 directory, 4 files

pyproject.toml #

The main hero of this post is the pyproject.toml. This is what defines all of our PEP 517 style project setup.

[project]
name = "pkg"
description = "Show how to version packages with hatch"
readme = "README.md"
dynamic = [
 "version",
]

[build-system]
requires = [
 "hatchling>=1.4.1",
]
build-backend = "hatchling.build"

[tool.hatch.version]
path = "pkg/__about__.py"

statically versioning #

project.version

It is possible to set the version number inside the pyproject.toml statically. This is fine if you just want to version your package manually, and not through the hatch cli.

[project]
name = "pkg"
version = "0.0.0"
# ...

Statically versioning in pyproject.toml will not work with hatch version

Cannot set version when it is statically defined by the `project.version` field

dynamically Versioning #

project.dynamic

Setting the project verion dynamically can be done by changing up the following to your pyproject.toml. Hatch only accepts a path to store your version. If you need to reference it elsewhere in your project you can grab it from the package metadata for that file. I would not put anything else that could possibly clash with the version, as you might accidently change both things.

If you really need to set it in more places use a package like bump2version.

[project]
name = "pkg"
dynamic = [
  "version"
]
# ...
[tool.hatch.version]
path = "pkg/__about__.py"

Note: you can configure hatch to use a different pattern https://hatch.pypa.io/1.2/version/#configuration, but I have not found it to be something that I need.

about.py #

The hatch project itself uses a about.py to store it’s version. It’s sole content is a single __version__ variable. I don’t have any personal issues with this so I am going to be following this in my projects that use hatch.

__version__ = "0.0.0"

Hatch has a pretty intuitive versioning api. hatch version gives you the version. If you pass in a version like hatch version "0.0.1" it will set it to that version as long as it is in the future, otherwise it will error.

# print the current version
hatch version

# set the version to 0.0.1
hatch version "0.0.1"

bumping #

You can bump parts of the semver version.

# minor bump
hatch version minor

# beta pre-release bump
# If published to pypi this can be installed with the --pre flag to pip
hatch version b

# bump minor and beta
hatch version minor,b

# release all of the --pre-release flags such as alpha beta rc
hatch release

Example #

Here is a screenshot of bumping a projet along.

GitOps #

In my github actions flow I will be utilizing this to automate my versions. In my side projects I use the develop branch to release –pre releases. I have all of my own dependent projets running on these –pre releases, this allows me to cut myself in my own projects before anyone else. Then on main I automatically release this beta version.

GitHub Actions #

Here is what the ci/cd for markata looks like. There might be a better workflow strategy, but I use a single github actions workflow and cut branches to release –pre releases and full release. These steps will bump, tag, commit, and deploy for me.

      - name: automatically pre-release develop branch
        if: github.ref == 'refs/heads/develop'
        run: |
          git config --global user.name 'autobump'
          git config --global user.email 'autobump@markata.dev'
          VERSION=`hatch version`
          # if current version is not already beta then bump minor and beta
          [ -z "${b##*`hatch version`*}" ] && hatch version b || hatch version minor,b
          NEW_VERSION=`hatch version`
          git add markta/__about__.py
          git commit -m "Bump version: $VERSION → $NEW_VERSION"
          git tag $VERSION
          git push
          git push --tags

      - name: automatically release main branch
        if: github.ref == 'refs/heads/main'
        run: |
          git config --global user.name 'autobump'
          git config --global user.email 'autobump@markata.dev'
          VERSION=`hatch version`
          hatch version release
          NEW_VERSION=`hatch version`
          git add markta/__about__.py
          git commit -m "Bump version: $VERSION → $NEW_VERSION"
          git tag $VERSION
          git push
          git push --tags

      - name: build
        run: |
          python -m build

      - name: pypi-publish
        if: github.ref == 'refs/heads/develop' || github.ref == 'refs/heads/main'
        uses: pypa/gh-action-pypi-publish@v1.1.0
        with:
          password: ${{ secrets.pypi_password }}

Hatch Version Action #

I am setting up a github custom action waylonwalker/hatch-version-action that will lint, test, bump, and publish for me in one step. More on that in the future.

From Markdown to Blog with Markata | lightning talk | python web conf 2022

2022-08-31T10:01:09Z

Markata is a great python framework that allows you to go from markdown to a full website very quickly. You can get up and running with nothing more than Markdown. It is also built on a full plugin architecture, so if there is extra functionality that you want to add, you can create a plugin to make it behave like you want.

Full transparancy… I built markata.

The talk #

The talk is live on YouTube. Make sure you check out the other videos from the conference. There were quite a few quality talks that deserve a watch as well.

I spoke at Python Web Conf 2022

2022-08-30T08:40:22Z

I spoke at python webconf in March 2022 about how I deploy this blog on a continuous basis.

Building this blog has brought me a lot of benefits. I have a set of custom curated notes to help describe a problem and how to solve it to me. At theis point it’s not uncommon to google an Issue I am having and finding my own blog with exactly the solution I need at the top.

I also bump into people from time to time that recognize me from the blog, its a nice conversation starter, and street cred.

I turned on 2FA for all of my pypi packages

2022-08-29T07:51:54Z

I got all the pypi packages that I own behind 2 factor authentication. 💪

Recently this really made it’s rounds in the python news since pypi was requiring critical package maintainers to have 2FA on and even offering them hardware tokens to help them turn this on.

I feel like this caused a bit of confusion as turning on 2FA does not mean that you need to do anything different to deploy a package, and it DOES NOT require a hardware token. You can continue using your favorite 2FA app.

You might wonder what this means for my projects. It means that to edit any sensitive content such as pull a new api token, add/remove maintainers, or deleting a release I need to use a TOPT (time based one time password) application such as Google Authenticator, Microsoft Authenticator, Authy, or FreeOTP.

This has very little change to my overall workflow as my CI system still automatically deploys for me with the same api token as before.

This is one small thing that maintainers can do to prevent supply chain attacks on their projects that they put so much work into.

When I log in I now get this extra screen asking for an auth token.

My packages #

Once I turned on 2FA for my account I could then turn on 2FA requirement for each project. I am not sure how much safety there is in pypi, it might require all maintainers to have it turned on before it allows packages to have it turned on.

Once turned on it requires anyone who maintains the project to have 2FA on to be able to edit any sensitive content.

use vim to remove duplicates

2022-08-25T06:50:32Z

I just love how some features of vim are so discoverable and memorable once you really start to grasp it. Sorting and uniqing your files or ranges is one of those examples for me.

" sort the file
:sort
" sort the file only keeping unique lines
:sort u


" sort a range
:'<,'> sort
" sort a range only keeping unique lines
:'<,'> sort u

I recently used this to dedupe my autogenerated links section for rich-syntax-range-style. More often I am using it to sort and uniqify objects like arrays and lists.

Here is what the markdown looks like.

* [py-tree-sitter](https://github.com/tree-sitter/py-tree-sitter)
* [rich](https://github.com/Textualize/rich)
* [@textualizeio](https://twitter.com/textualizeio)
* [rich](https://github.com/Textualize/rich)
* [another post](https://waylonwalker.com/designing-kedro-router)
* [print-register-pipelines](https://screenshots.waylonwalker.com/print-register-pipelines.webp)
* [rich](https://github.com/Textualize/rich)
* [console-print-register-pipelines](https://screenshots.waylonwalker.com/console-print-register-pipelines.webp)

Then typing vap:sort u yields a uniqly sorted list of links.

Highlighting text ranges with Rich | python

2022-08-24T20:06:34Z

Today I’ve been playing with py-tree-sitter a bit and I wanted to highlight match ranges, but was unable to figure out how to do it with rich, so I reached out to @textualizeio for help.

https://twitter.com/_WaylonWalker/status/1562469770766589952

While waiting for that reply let’s show how we got this far.

imports #

Lets import all the classes that we need from rich and setup a console to print to.

from rich.console import Console
from rich.syntax import Syntax
from rich.style import Style

console = Console()

some code #

Now we need some code to highlight. I am going to rip my register_pipeline from another post.

code = '''
from find_kedro import find_kedro

def register_pipelines(self) -> Dict[str, Pipeline]:
    """Register the project's pipeline.
    Returns:
        A mapping from a pipeline name to a ``Pipeline`` object.
    """
    return find_kedro()
'''

print #

We could simply print out the code we have as a variable, but thats a bit hard to read.

console.print #

printing with rich’s console makes it a little better, but not much by default.

Syntax #

We can pull from rich’s syntax module to really pretty this up.

syntax = Syntax(code, 'python', line_numbers=True)
console.print(syntax)

Now we are getting some really impressive print outs right in the terminal!

note that I have ipython set to use rich, you will need to console.print() in scripts

highlight lines #

Now we can start highlighting lines right when we initialize our Syntax instance. It looks ok. It’s not super visible, but more importantly its not granular enough. I want to highlight specific ranges like the word register_pipelines.

syntax = Syntax(code, 'python', line_numbers=True, highlight_lines=[4])
console.print(syntax)

This hows the line, but still is not very accurate.

highlight text #

[@textualizeio] got back to me, let’s see if What we can do with stylize_range!

https://twitter.com/textualizeio/status/1562487302274043904

syntax = Syntax(code, 'python', line_numbers=True)
style = Style(bgcolor='deep_pink4')
syntax.stylize_range(style, (4, 4), (4, 22))
console.print(syntax)

This gives us the final result we are looking for, we can easily see what is being targeted here. In this case the function name register_pipelines.

This turns out to be exacly what I am looking for. Now I have an easy way to print out highlighted code wtih my py-tree-sitter query results.

vimgrep open buffers

2022-08-22T13:17:32Z

How to vimgrep over hidden files.

I needed to delete all build pipeline steps that were named upload docs. I currently have about 60 projects running from the same template all running very similar builds. In the past I’ve scripted out migrations for large changes like this, they involved writing a python script that would load the yaml file into a dictionary, find the corresponding steps make the change and write it back out.

Today’s job was much simplar, just delete the step, were all steps are surrounded by newlines. My first thought was to just open all files in vim and run dap. I just needed to get these files:positions into my quickfix. My issue is that all the builds reside within hidden directories by convention.

The issue #

variability

After searching through all the projects it was clear that all the steps were in their own paragraph, though I was not 100% confident enough to completely automate it, and the word upload docs was in the paragraph.

some were a two liner

- name: upload docs
  script: aws s3 ...

Some had a variation in the name

- name: upload docs to s3
  script: aws s3 ...

some were more than 2 lines.

- name: upload docs
  script: |
    aws s3 ...

some used a different command.

- name: upload docs
  script: |
    python ...

Templates are great #

but they change

Templates are amazing, and tools like cookiecutter and copier are essential in my workflow, but those templates change over time. Some things are a constant, and others like this one are an ever evolving beast until they are tamed into something the team is happy with.

vimgrep over hidden files #

I know all the files that I care to search for are called build.yml, and they are in a hidden directory.

:args `fd -H build.yml`
:vimgrep /upload docs/ ##

Once opened as a buffer by using args, and a handy fd command I can vimgrep over all the open buffers using ##

Open buffers are represented by ##

Now I can just dap and :cnext my way through the list of changes that I have, and know that I hit every one of them when I am at the end of my list. And can double check this in about 10s by scrolling back through the quickfix list.

markata 0.3.0 is 15-20% faster

2022-08-21T13:53:20Z

a sprinter edging out his opponent by Dall-e

It’s about time to release Markata 0.3.0. I’ve had 8 pre-releases since the last release, but more importantly it has about 3 months of updates. Many of which are just cleaning up bad practices that were showing up as hot spots on my pyinstrument reports

Markata started off partly as a python developer frustrated with using nodejs for everything, and a desire to learn how to make frameworks in pluggy. Little did I know how flexible pluggy would make it. It started out just as my blog generator, but has turned into quite a bit more.

Over time this side project has grown some warts and some of them were now becoming a big enough issue it was time to cut them out.

Let’s compare #

I like to use my tils articles for examples and tests like this as there are enough articles for a good test, but they are pretty short and quick to render.

mkdir ~/git/tils/tils
cp  ~/git/waylonwalker.com/pages/til/ ~/tils/tils -r
cd ~/git/tils/tils

running tils on 0.2.0 #

At the time of writing this is the current version of markata, so just make a new venv and run it.

python3 -m venv .venv --prompt $(basename $PWD)
pip install markata
markata clean
markata build

cold tils: 14.523 warm tils: 1.028

running tils on 0.3.0b8 #

python3 -m venv .venv --prompt $(basename $PWD)
# --pre installs pre-releases that include a b in their version name
pip install markata --pre
markata clean
markata build

cold tils: 11.551 (+20%) warm tils: 0.860 (+16%)

pyinstrument #

These measurements were taken with pyinstrument mostly out of convenience since there is already a pyinstrument hook built in, but also because I like pyinstrument.

Here is the pyinstrument report from the last run.

My Machine #

This comparison was not very exhaustive. It was ran on my pretty new to me Ryzen 5 3600 machine.

The changes #

Most of these changes revolve in how the lifecycle is ran. It was trying to be extra cautious and run previous steps for you if it thought it might be needes, in reality it was rerunning a few steps multiple times no matter what.

The other thing I turned off by default, but can be opted into, is beautifulasoup’s prettify. That was one of the slower steps ran on my site.

0.3.0 #

It should be out by the time you see this, I wanted to compare the changes I had made and make sure that it was still making forward progress and thought I would share the results.

name it claim it aim it

2022-08-04T14:28:30Z

Deliberative #

People exceptionally talented in the Deliberative theme are best described by the serious care they take in making decisions or choices. They anticipate obstacles.

I am risk-adverse. I want everything well thought out and calculated before I make any sort of change. I have never gambled in my life and just the thought of it makes me anxious.

Aim it #

I can use this as a strength to plan out potential issues and prevent them. I do this quite often with my role in infrastructure.

I need to make sure that I use deadlines to keep this as a strength and not hinderence.

Automation #

One of the biggest ways that I utilize this skill is automation. I am all about automating things, not just because I don’t want to do the manual work, but I am not sure when I am going to need to do something again.

get the version of any python package | python api

2022-07-29T15:48:36Z

A common meta thing that I need in python is to find the version of a package. Most of the time I reach for package_name.__version__, but that does not always work.

but not all projects have a `version` #

In searching the internet for an answer nearly every one of them pointed me to __version__. This works for most projects, but is simply a convention, its not required. Not all projects implement a __version__, but most do. I’ve never seen it lie to me, but there is nothing stopping someone from shipping mismatched versions.

If you maintain a project ship a `version` #

I appreciate it

While its not required its super handy and easy for anyone to remember off the top of their head. It makes it easy to start debugging differences between what you have vs what you see somewhere else. You can do this by dropping a __version__ variable inside your __init__.py file.

## __init__.py
__version__ = 1.0.0

SO #

stack overflow saves the day

Special thanks to this Stack Overflow post for answering this question for me.

So what do you do… #

importlib

Your next option is to reach into the package metadata of the package that you are interested in, and this has changed over time as highlighted in the stack overflow post.

for Python >= 3.8:

from importlib.metadata import version

version('markata')
# `0.3.0.b4`

I only really use python >= 3.8 these days, but if you need to implement it for an older version check out the stack overflow post.

Another option.. #

use the command line

Another common option uses pip at the command line.

❯ pip show markata
Name: markata
Version: 0.3.0b4
Summary: Static site generator plugins all the way down.
Home-page: https://markata.dev
Author: Waylon Walker
Author-email: waylon@waylonwalker.com
License: MIT
Location: /home/waylon/git/waylonwalker.com/.venv/lib/python3.11/site-packages
Requires: anyconfig, beautifulsoup4, checksumdir, diskcache, feedgen, jinja2, more-itertools, pathspec, pillow, pluggy, pymdown-extensions, python-frontmatter, pytz, rich, textual, toml, typer
Required-by:

And if the package implements a command line its common to ship a version command such as --version or -V.

❯ markata --version
Markata CLI Version: 0.3.0.b4

Why did I need to do this? #

Well we have a cli tool that wraps around piptools and we wanted to include the version of piptools in the comments that it produces dynamically. This is why I wanted to dynamically grab the version inside python without shelling out to pip show. Now along with the version of our internal tool you will get the version of piptools even though piptools does not ship a __version__ variable.

Fin #

In the end, I am glad I learned that its so easy to use the more accurate package metadata, but still appreciate packages shipping __version__ for all of us n00b’s out here.

Two new shell aliases for git

2022-06-28T12:31:10Z

Recently I added two new bash/zsh aliases to make my git experience just a tad better.

trackme #

Most of our work repos were recently migrated to new remote urls, we scriped out the update to all of the repos, but I was left with a tracking error for all of my open branches. To easily resolve this I just made an alias so that I can just run trackme anytime I see this error.

There is no tracking information for the current branch.
    Please specify which branch you want to merge with.
    See git-pull(1) for details

    git pull <remote> <branch>

If you wish to set tracking information for this branch you can do so with:

    git branch --set-upstream develop origin/<branch>

getting the branch #

The following command will always return the currently checked out branch name.

git symbolic-ref --short HEAD

Injecting this into the suggested git command as a subshell gives us this alias that when ran with trackme will automatically fix tracking for my branch.

alias trackme='git branch --set-upstream-to=origin/$(git symbolic-ref --short HEAD)'

rebasemain #

I sometimes get a bit lazy at checking main for changes before submitting any prs, so again I made a quick shell alias that will rebase main into my branch before I open a pr.

alias rebasemain='git pull origin main --rebase'

The Aliases #

Here are both of the alias’s, feel free to steal and modify them into your dotfiles. If you are uniniatiated a common starting place to put these is either in your ~/.bashrch or ~/.zshrc depending on your shell of choice.

alias trackme='git branch --set-upstream-to=origin/$(git symbolic-ref --short HEAD)'
alias rebasemain='git pull origin main --rebase'

IPython q to exit

2022-06-13T10:10:34Z

So many terminal applications bind q to exit, even the python debugger, its muscle memory for me. But to exit ipython I have to type out exit<ENTER>. This is fine, but since q is muscle memory for me I get this error a few times per day.

╭─────────────────────────────── Traceback (most recent call last) ────────────────────────────────╮
│ <ipython-input-1-2b66fd261ee5>:1 in <module>                                                     │
╰──────────────────────────────────────────────────────────────────────────────────────────────────╯
NameError: name 'q' is not defined

After digging way too deep into how IPython implements its ExitAutoCall I realized there was a very simple solution here. IPython automatically imports all the scripts you put in your profile directory, all I needed was to create ~/.ipython/profile_default/startup/q.py with the following.

q = exit

It was that simple. This is not a game changer by any means, but I will now see one less error in my workflow. I just press q<Enter> and I am out, without error.

Copier Slugify | python templating | using cookiecutter

2022-06-11T12:37:50Z

It’s no secret that I love automation, and lately my templating framework of choice has been copier. One hiccup I recently ran into was having spaces in my templated directory names. This makes it harder to run commands against as you need to escape them, and if they end up in a url you end up with ugly %20 all over.

Cookiecutter has the solution #

Yes the solution comes from a competing templating framework.

I install copier with pipx, so I need to inject cookiecutter in to my copier environment to use the slugify filter.

pipx inject copier cookiecutter

If you are using a normal virtual environment you can just pip install it.

pip install copier cookiecutter

add the extension to your template #

copier.yml

Now to enable the extension you need to declare it in your copier.yml file in your template.

_jinja_extensions:
    - cookiecutter.extensions.SlugifyExtension

Use it | slugify #

use-it

Now to use it, anywhere that you want to slugify a variable, you just pipe it into slugify.

❯ tree .
.
├── copier.yml
├── README.md
└── {{ site_name|slugify }}
    └── markata.toml.jinja

1 directory, 3 files

Here is a slimmed down version of what the copier.yml looks like.

site_name:
  type: str
  help: What is the name of your site, this shows in seo description and the site title.
  default: Din Djarin

_jinja_extensions:
    - cookiecutter.extensions.SlugifyExtension

Results #

Running the template looks a bit like this.

straight from their docs #

The next section is straight from the cookiecutter docs

Slugify extension #

The cookiecutter.extensions.SlugifyExtension extension provides a slugify filter in templates that converts string into its dashed (“slugified”) version:

{% "It's a random version" | slugify %}

Would output:

it-s-a-random-version

It is different from a mere replace of spaces since it also treats some special characters differently such as ' in the example above. The function accepts all arguments that can be passed to the slugify function of python-slugify_. For example to change the output from it-s-a-random-version to it_s_a_random_version, the separator parameter would be passed: slugify(separator='_').

Textual has devtools

2022-06-09T21:21:11Z

Textual has devtools in the upcoming css branch, and its pretty awesome!

It’s still early #

Textual is still very early and not really ready for prime time, but it’s quite amazing how easy some things such as creating keybindings is. The docs are coming, but missing right now so if you want to use textual be ready for reading source code and examples.

On to the devtools #

As @willmcgugan shows in this tweet it’s pretty easy to setup, it requires having two terminals open, or using tmux, and currently you have to use the css branch.

https://twitter.com/willmcgugan/status/1531294412696956930

Why does textual need its own devtools #

Textual is a tui application framework. Unlike when you are building cli applications, when the tui takes over the terminal in full screen there is no where to print statement debug, and breakpoints don’t work.

getting the css branch #

In the future it will likely be in main and not need this, but for now you need to get the css branch to get devtools.

git clone https://github.com/Textualize/textual
git fetch --alll
git checkout css

install in a virtual environment #

Now you can create a virtual environment, feel free to use whatever virtual environment tool you want, venv is built in to most python distributions though, and should just be there.

python3 -m venv .venv --prompt textual
source .venv/bin/activate
pip install .

Now that we have textual installed #

Once textual is installed you can open up the devtools by running textual console.

textual console

Using Different versions of python with pipx | pyenv

2022-05-28T20:38:42Z

I love using pipx for automatic virtual environment management of my globally installed python cli applications, but sometimes the application is not compatible with your globally installed pipx

Which version of python is `pipx` using?? #

This one took me a minute to figure out at first, please let me know if there is a better way. I am pretty certain that this is not the ideal way, but it works.

My first technique was to make a package that printed out sys.version.

# what version of python does the global pipx use?
pipx run --spec git+https://github.com/waylonwalker/pyvers pyvers

# what version of python does the local pipx use?
python -m pipx run --spec git+https://github.com/waylonwalker/pyvers pyvers

Let’s setup some other versions of python with pyenv #

If you don’t already have pyenv installed, you can follow their install instructions to get it.

pyenv install 3.8.13
pyenv install 3.10.5

I usually require a virtual environment #

I set the PIP_REQUIRE_VIRTUALENV environment variable to true to ensure that the virtual environment is activated when pip installing, this makes it so that I can’t accidentally use the global env, which is typically not what I want to do.

export PIP_REQUIRE_VIRTUALENV=true
# for windows users
set PIP_REQUIRE_VIRTUALENV=true

This goes right into my shell startup script ~/.bashrc or ~/.zshrc.

Exceptions happen #

This is my one exception. I’ve had better luck putting pipx right in the global python environment. Not the system python, but each python version that I install with pyenv.

export PIP_REQUIRE_VIRTUALENV=false
# for windows users
set PIP_REQUIRE_VIRTUALENV=false

Let’s install pipx #

First up is python 3.10.5

pyenv global 3.10.5
pip install pipx
pipx run --spec git+https://github.com/waylonwalker/pyvers pyvers

3.10.5 (main, Jun  6 2022, 18:49:26) [GCC 12.1.0]

Next is python 3.8.13j

pyenv global 3.8.13
