Running Pixelflut on a 2010 router

I have been very involved in the Pixelflut space for a few years. At GPN24 , some beings, including myself, formed a “special interest group” for Pixelflut including a Codeberg org , a new website , and work began on an RFC. And during that time, I also acquired a TP-Link Archer C7 (v2). A neat little all-in-one consumer router with WiFi, which notably is a well-supported OpenWRT platform. No…

No Generative AI In Anything I Publish

TL;DR: There is no “generative AI” in any project or thing I publish to the internet , whether front-facing or as a non-visible part of the creation process. This applies to this website, the software I write, any other creative works I publish, as well as any art affiliated with me. I am strongly opposed to generative AI, most importantly diffusion image/video generation and large language…

Debian’s ifupdown is a Dumpster Fire

Debian, in a case of being Debian that surprises absolutely noone, has a networking tool called ifupdown , alternatively known as /etc/network/interfaces (the config file) or by the binary names ifup and ifdown . This is not a standard cross-distro tool, but it’s also not the only way of doing network configuration on Debian. In fact, the first section on the Wiki page is literally called 4 ways…

Cthulhu’s Integration: CI Sucks, How to Improve It

I have been writing CI pipelines for the past three days straight. Well, that’s an understatement. I have been writing CI pipelines for a long time. Half of my dayjob at one point was writing CI pipelines for JetBrains TeamCity . I wrote my own CD tool at the start of this year for this exact website because everything else didn’t fit my needs. I operate no less than four Forgejo Actions runners.…

Rust Async is Just Set Theory

Recently, while working on penplot , I was having an epiphany looking at async combinators. By “combinators”, I mean select , join , race , and any others that perform some generic-higher-level action across multiple futures, allowing for complex program flow within a task. These all have quite nice parallels in theoretical computer science, namely formal languages and more generally set theory.…

Forgejo AI defense with iocaine

This post was written for iocaine 2. Version 3 changed the way that scripts work significantly, including having to generate your own garbage. I have since rewritten my handler script as a modified version of the default script with a slightly customized HTML template. All of the checks explained below still exist, just with different Roto syntax. I would recommend that you start by using the…

Penplot Part 1: An early look

I have been teasing my work on Penplot for a while now, but never coherently talked about what it actually is. So today I am changing that, with a first blog post about the history and early development of Penplot, my CNC plotter project. MANGOLD-X: Where it all started At its core, Penplot started in 2018. I was in highschool back then, and one of the best and most impactful classes I took since…

Electric Vehicles are the Least Bad Option

… as long as trains are not an option, obviously. Some of my opinions on EVs, cars, and why I think they’re often okay. This post is a bit all over the place, but these thoughts need writing down – please treat each section as its own independent minipost.

Switching away from Windows

I am writing this blog post on an Arch Linux that’s barely 2 days old. It is the permanent replacement for a Windows 10 install, which I have now been using since 2020. At the start of 2025, my last Microsoft Windows OS install in existence was wiped and retired for good, replaced by another Linux install. Why I did this, and why now, is the topic of this blogpost.

File Organization: My approach

I think file organization is still one of the big unsolved problems of computing. Everyone has so many goddamn files, and yet, barely anyone has figured out how to organize them properly. For me, it’s an even bigger problem: I’m a data hoarder! I store all the data! I inherited that from my dad, who (different from me) doesn’t even throw out the bad holiday pictures. (We have 1.2 terabytes of…

Archiving Blu-Rays: A Good Way

Note: This is not legal advice, but making a backup copy of physical discs that you own is legal in all common jurisdictions. Giving away those backups is illegal piracy, and you can decide for yourself if you care about the illegality or not. I’m neither your lawyer nor your babysitter nor responsible for your crimes. Since streaming is starting to suck again, if you’re not already sailing you…

The RIRs Need to Fix Their Statistic Formats (Rant)

TL;DR: If you work for a RIR, and you’re in a position to fix this mess, there’s a list below with every specific issue the currently provided statistics have, and what I think should be done in the cases where the solution is non-obvious. If you are here for the full story, I think it may be interesting to start at the beginning.

Regarding the Summer 2024 SerenityOS leadership changes

I’m a bit late to the party, but I have quite a few things to say about the leadership changes in the SerenityOS project that happened recently. Be warned: this is an extremely opinionated opinion piece that’s entirely my opinion, so you will only find my own opinions within it.

My thoughts on 37c3

So I have a few thoughts on #37c3, and this will be a long and personal one. Let me start by being overly generic, just like I usually do, and get to a point later on. It’s a good one I promise :)

Peace, Love, and Genderqueerness

My 2022 album “Peace, Love, and Genderqueerness” contains a mixture of some of my early music, with trance, VGM, and lo-fi tracks.
