Kelsey has a really good lightbulb moment here about platform engineering.
“if you had to do all the deployments for the entire company what questions would you ask of the development team?”
That’s your api, your platform, this is your product as a platform engineer. It’s not images, docker, terraform, hcl, yaml, kubernetes, It’s building out the right api for your company to deploy its products effectively.

notifications for static site builds
This morning I set up notifications for changes to my static site builds
leveraging git name status [1] and ntfy.
References:
[1]: /git-name-status/
--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}'

The Right Reasons To Run Kubernetes In Your Homelab
Running kubernetes in your homelab [1] is a fantastic way to learn, explore, express
yourself, and run services that you use.

You want to learn kubernetes # [4]
Homelabbing is a such a great way to learn new skills, deploy real apps that
you use. Create new custom apps for your specific use cases that no one else
has. You should absolutely run kubernetes in your homelab if you want to learn it.
I would recommend to start locally, pull up kind, minikube, or k3d and start
from your local machine before putting it on a server.
When you decide you are ready for a server, you probably don’t need any crazy
hardware. You can probably run on some old retired Dell Optiplex or an old
desktop someone is throwing out as it no longer runs windows.

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

and in docker compose

I did not realize all the places to be considered as AI water usage. Hank goes deep highlighting all of the sources he is aware of, most reports leave off a lot of these sources, some reports go maybe too far adding sources that may not make sense depending on the question you are asking.
As someone that runs computers with gpus in their house, and watching LTT make AIO installs on GPUs I’ve wondered what would AI use water for, now I understand that its a lot. No where near agriculture, but a lot.
Unlike running a gpu in your house, potentially with a closed loop AIO, data centers are filled with hardware making heat and it all must go somewhere. Current technology has this done with evaporative cooling, i.e. its not a closed loop, the water goes into the sky.
He goes on to point out that its not just the data center, using water, but also chip fab and power plants.
Something I hadn’t put a lot of thought into is the type of water. While a lot of agriculture and power applications do not use municipal water, a lot of data centers do, putting excess strain on water treatment.
Something I find interesting is that Altman is doing the same thing here that he does on his fin...

Age verification hitting bluesky?? At least its not yet requiring your govt issued id or anything, but stepping that direction. I don’t know how I feel about age checks, does it actually protect kids when parents aren’t involved? I can’t say anything there, but it really does feel like its about ready to hurt the rest of us, requiring us to whip out ids and personal data for anything done online. This is a real problem that is hard to solve, and reasons why it has not been solved yet.

damn this is a rough one. A users entire home directory removed by claude code from an rm command.
rm -rf tests/ patches/ plan/ ~/
Reading the first half of that command it LGTM. If you had approved rm, you are hosed. If this is inside a larger script its running, you really gotta read close. This one still feels pretty obvious, but I can imagine some bash doing some nasty things I miss if I read it and understand it let alone glance at it.
I’ll take this as a reminder that I really need to be paying full-ass attention to agents, and moving towards a better sandbox for them, something in docker, maybe something like distrobox that is a magic wrapper over podman that just gives you the things you need for what it does. Something that starts up with access to start web servers, run agentic cli of choice, see project, git [2] commit. It feels like the right thing has a lot of what distrobox does, but distrobox has too much and would be prone to this us...

There is an npm package <a href="https://zachleat.com" class="mention" data-name="Zach Leatherman" data-bio="A post by Zach Leatherman (zachleat)" data-avatar="https://www.zachleat.com/og/opengraph-default.png" data-handle="@zachleat">@zachleat</a>/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. -->
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.
Not every print needs supports
Not every print needs supports. So many models default to having it on,
whether needed or not. Well designed parts, designed for 3d printing almost
never need supports (depending on constraints).

This looks like a really good low cost option for some workholding. There is never a shortage of workholding in the shop and everything has a place. Having something low cost that you can have a bunch of makes a lot of sense. Maybe you still need a super scucum unit for really clamping the shit out of something, but this easily covers most use cases in a garage workshop. I want to build it.

Moore’s Law is Dead pitches a pretty ingenious sku for the new gabecube aka steam machine. I fully support repairability and ewaste reduction. most of these components have not had MAJOR improvements in years, hence his channel name. There is a possibility here that Valve could ship with their unique hardware, (apu, psu, case, ports, networking) and let you bring your own ssd and ram from an old device that you might not use anymore. I love this idea. At the same time it feels like entering the star wars universe where there are no more new manufacturing and everything is cobbled together from old hardware made long ago.

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)

What a heart breaking video to listen to. I’m trying to do a better job of being positive right now. I’m trying to look at the world in what I have control over (not much more than my attitude about it). AI is killing so much right now I’m trying to look at it as the good tools the engineers made it to be. Ownership is dying around every goddamn corner. Hats off to Edison, this guy gets it. We need more companies like this taking a stand for the average person who wants to make it out there.

What a great campfire story Casey stumbled into. Whether any of this is true few will ever know, but its very reasonable that a race condition and a stalled job to apply configuration caused by someone who left the company 10 years ago caused an outage. I find it hilarious that they call this guy he answers, yup I still know the password, but how do I know you’re legit, I’m not just handing out the password. Casey did a stand up job telling this story.

Linus is Techbrophobic [1] like the rest of us. This is such an unexpectedly mild take from him. I expected some threat to the mother of the vibe coder, but he gave a pretty great middle of the road take. The industry sucks, it smells off, we know a lot wrong with it, it feels like theres a lot more wrong than we know. But the tools that its making are really good when used in the right ways. They are not a replacement for anything, they are assistive. They can lift someone from not knowing how to code to making a small webapp for their use. Someone who wants to write backend and give them a decent front end, someone who whats to write front end and give them a decent backend.
Great take from someone with more experience than most can ever dream of having, worth a listen.

The Wrong Reasons To Run Kubernetes In Your Homelab
Running kubernetes in your homelab [1] is complex, time consuming, there are almost
no docs to help you (homelab focused docs for things you want to install), and
nothing is copy paste. You have to make everything happen yourself.

No it’s not. It’s much different than running docker, compose, swarm. It’s
meant for scale, it’s complex, it’s made for enterprise, not your local
development or your homelab. It can do these things, it can do them quite
well, but it’s not the target audience.

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

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.

I did not realize that David’s site was built on a homegrown Static Site Generator. As someone who also does this myself I appreciate the effort. I build my site on markata [2]. It started as a project to learn a set of tools and has become a project that I depend on everywhere and cant put down. It’s a great tool, but you probably shouldn’t use it. Anyways, I feel this really shows on David’s site. His site is filled with custom features that make it very unique, one off, and always a pleasure to read.

gpus are awesome
GPU's are awesome. I just added gpu support to my bambu-studio distrobox and
its flying! On my wayland based system the native package has never worked,
(arch or bazzite), but running in a distrobox does. Outside of distrobox the 3d
rendering canvas is black, no output. It used to work fine without gpu
support, was snappy enough, complex models were a bit sluggish, but fine.
Lately something happened and simple models bring it to its knees. It got
unusable!
