grafana dashboards as k8s configmap

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. imag

ruff single line import

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. Turns out I was missing I sort in the select list.

Markata list posts by year

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. !!! 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 You could use the command as well right within your shell and the same map and filte

pre-commit exclude

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.

newlines in css before

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 I need to use and . Here is what it looks like on my not yet live implementation of fragmentions. screenshot-2025-02-15T15-43-06-372Z.png

testing nvim installs

Testing fresh nvim installs can be a pain, and hard to di without borking your known good install. I've been using 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. I've started to use this as a recipe to run before deploying a new version of my dotfiles. So far its pairi

vim date

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. 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 . It outputs the following Sat Feb 1 08:53:20 PM CST 2025 codeium just taught me this one with autocomplete This outputs the following 2025-

aptitude why

Today I ran into an interesting question, why am I being asked to configure tzdata while installing npm. Turns out that the cli has a why command that very handily nails down why you have something installed on a debian based system. Install aptitude Why tzdata Now we can query why we need tzdata and see the full chain with the root package being .

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. Why tzdata Checking aptitude why tzdata it shows that the chain goes back through npm. The solution, configure tzdata !!! TIP DEBIAN_FRONTEND=noninteractive This is required, because apt installing tzdata will trigger the interactive prompt. You will manually con

bc

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 . All you need is a string of math on the line you want to calculate, go to normal mode and run to get the answer. Traditionally I will open my system ca

tailwind aspect

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 class to achieve this. Example screenshot-2025-01-31T14-50-00-094Z.png {.cinematic}

markdown it attrs with slashes dont work

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. Given the following markdown with attrs added to the image and to the paragraph block. We get the following output with only the middle one working correctly. screenshot-2025-01-31T14-50-00-094Z.png {.aspect-[2.39/1]} screenshot-2025-01-31T14-50-00-094Z.png {.cinematic} {.cinematic} screenshot-2025-01-31T14-50-00-094Z.png !!!

setting up nvim-manager starship prompt

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 environment variable is not set, and it shows which nvim I am using if it is set.

emoji in headless chrome in docker

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. Before Here's what they were looking like with broken emoji fonts. image After And now with the fixed emoji font. image I put thought bubbles on my thoughts posts and stars on my github stars posts

postiz-file-upload

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

Links rely on color to be distiniquishable

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. screenshot-2024-12-18T02-25-53-014Z.png 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 much better now. screenshot-2024-12-18T02-45-53-807Z.png Now I got that 100 A11y score in lighthouse

Today I discovered the function in bash from the ujust tool from ublue.it . Seems like a cool trick, but might not work everywhere.

debug cloudflared tunnel

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.

Obsidian-new-file

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. Obsidian gives you a keybinding 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.

Slug

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.

Vim-gq

Vim has a handy feature to format text with . You can use it in visual mode, give it a motion, or if you give it it will format the current line. I use this quite often while writing in markdown, I do not use softwraps in vim, so 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 to format the whole paragraph and not just the current line. before formatting vim-gq-20240805122634078.we

Obsidian-go-to-definition

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

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

Obsidian Image Converter

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. obsidian-image-converter-20240731211310793

convert mp4 for twitter with ffmpeg

I've had a couple of uploads to twitter fail recently and has been a pain. I tried some online converters for convenience, but none of them worked. I reached out to chatgpt and found succeess with this ffmpeg command.

k8s kustomize diff

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. You can enable color diffs by using an external diff provider like colordiff. You might need to install colordiff if you don't already have it. Now I can try out kustomize changes and see the change with kustomize diff.

animal well keyboard

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 2 - open item menu / triangle 3 - right item / lb

diskcache as debounce

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 [[ python-diskcache ]] 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.

Install sealed-secreats via manifest

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.

playerctl fixes arch media keys

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. 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.

tailwind post template

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. {.mx-auto .block .w-fit .mb-0} Check out

tailscale ssh

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. I picked this up from the tailscale youtube channel. Tailscale {.youtube-embed}

Latest Page in Markata

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. Setting up the feed Feeds are setup in configuration. They provide a handy way to create an html feed, rss feed, and quickly reference a filtered set of posts like this. For more information on markata check out the full [[ markata ]] post.

How to List Sqlite tables

You can inspect sqlite tables with the sqlite shell. note that you get into the shell with I also learned that , and are helper functions that query the table on the 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.

Redka Runs on SQLite

With the liscense changes to redis there are several new forks out there. One that I am particularly interested in is redka . 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. We can look at the values in the vstring table.

Am I vulnerable to the xz backdoor?

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 paru, and I am good.

arch dependencies

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. You can check all the packages depended on by nodejs by running the following. This is everything from all of the repos you have configured, not what you have installed.

copier trust

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

ipython f2

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 for me, and since I have my environment variable set to it opens nvim when I hit . Today I discovered that Ipython has this bound to . If you know how to set it to let me know I've tried, a lot. better yet add to your .zshrc

python 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. Now when I run my tests will fail because my assert has no value, but if I run it will fill out my snapshot values and the file will then look like this. It also works with pydantic models.

sqlmodel indexes

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 example courtesy of the docs !!! Note primary keys are indexed by default. The docs cover this pretty well, and in quite depth - Optim

sqlite vacuum

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

Tailwind Animations

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. And the entire square element.

How to kill ollama server

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 You can confirm this with the following command. Next time you want to start you can do it as before with .

Composing Typer clis

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 cli which always has the pattern. Lets setup the cli app itself first. You can put it in . 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 o

tailwind arbitrary values

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. Learn more about using-arbitrary-values from their docs docs

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 and pushed it to dockerhub. It uses a secret to access cloudflare, and the entrypoint itself does the build and upload.

jinja macros

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.

jinja loop variable and htmx

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. 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 Starlette does not support url_for with query params. When trying to use url_for with query params it throws the following error. In my searching for this I found starlette issue #560 quite helpful, but not complete, as it did not work for me. !!!

setting up a kind cluster with argocd installed

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. 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 an

kubernetes kubeseal

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.

cli auth

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 as the username and 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 The og of command line url tools. wget My go to if I wan

Hiding Form input During htmx Request

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 Let's start off with the form. It uses htmx to submit a post request to the route. Note that there

Stripe Cancellations in FastAPI and SQLModel

Today I am working on fokais.com, trying to get to a point where I can launch by workig through stripe integrations.

nvim navic

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.

I have a set of custom curated notes to help describe a problem and how to solve it to me.

I also bump into people from time to time that recognize me from the blog, its a nice conversation starter, and street cred. The

I turned on 2FA for all of my pypi packages

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

use vim to remove duplicates

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. 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. Then typing yields a uniqly sorted list of links.
