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. The Right Reasons To Run Kubernetes In Your Homelab # [2] There are not many - You want to learn kubernetes - You like kubernetes - You want to learn to scale There are also The Wrong Reasons To Run Kubernetes In Your Homelab [3] 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. You like ku...

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"

Why is Everyone So Wrong About AI Water Use?? - YouTube www.youtube.com
- 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...

Notes – 05:09 Tue 9 Dec 2025 Notes – 05:09 Tue 9 Dec 2025 dbushell.com · dbushell.com [1] 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. References: [1]: https://dbushell.com/notes/2025-12-09T05:09Z/
Deprecations via warnings don’t work for Python libraries simonwillison.net
Deprecations via warnings don’t work for Python libraries Seth Larson reports that urllib3 2.6.0 released on the 5th of December and finally removed the HTTPResponse.getheaders() and HTTPResponse.getheader(name, default) methods, which have been marked as... Simon Willison’s Weblog · simonwillison.net [1] Deprecation warnings are so easy to miss, ignore, become numb to. Creating tools and processes to catch and address these issues is important.

A quote from Claude simonwillison.net
A quote from Claude I found the problem and it's really bad. Looking at your log, here's the catastrophic command that was run: rm -rf tests/ patches/ plan/ ~/ See that ~/ at the … Simon Willison’s Weblog · simonwillison.net [1] 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...

OG is short for open graph, a set of standard meta tags that are used for social media sharing. This is what tells other websites how to describe and display your site when shared on social media, text messages, or discord.

One Year Of Shots

I’ve been running my shot scraper api for a year now. It creates og [1] images for my website and thumbnails for my Reader [2] using a headless chrome instance. - 25870 shots - 73 shots per day on average - 12-09-2025 first shot taken Histogram # [3] [4] a histogram of shot counts by day You can see in the histogram that I’ve had a few big spike days, This has been mostly for days that I’ve integrated into a new service or changed the endpoint.

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 <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.

Steam Machine CAN Start at $399 with THIS SKU! | Cut Down Yiel... www.youtube.com
- 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.
