1 curl -I gabevenberg.com Dean Hansen, a dear friend of my family and of mine, died six months ago today. This isn’t the first death I’ve experienced in my life, but it was the first unexpected one. It hit me hard. I ended up flying back to the US on short notice to attend his funeral. Other than attending his funeral and being there for his family, there wasn’t a whole lot I can do. But I had to do something. So for the first time in my life, I added the name of someone I knew personally to the Clacks Overhead. ...

Well, this article has been a long time coming… Originally this post was going to be about moving my homelab overseas and what that process looked like, yet my homelab is still stuck in the US. Still, I figured I should write something. Most of my homelab had to stay in the US. Between our German apartment having atrocious upload speed, the increased price of electricity here, and the recent RAM and HDD price increases, I am not able to justify building a new server and hosting it in my apartment. Thankfully a friend of mine in the US offered to let me co-locate in his basement, for which I am extremely grateful. ...

TRRS (Tip Ring Ring Sleeve, or, as you may know it, “headphone jack with microphone support”) cables have long been the go to connector between split keyboard halves. They are cheap, compact, and thanks to their popularity, come in a variety of aesthetic styles. However, TRRS jacks were only designed for passive electrical components, and expose one large flaw when used actively. When a TRRS cable is (dis)connected, the tip of the plug will slide past every single contact of the jack. Likewise, the first contact of the jack will slide past every contact of the plug. ...

NixOS is really nice for self hosting. Anything that has a NixOS module can be hosted in a few lines of nix code. But what if the service we want to host doesn’t come with a NixOS module written for us already in Nixpkgs? This is where NixOS can be a little hard, as a guide on setting up a service in Debian or Arch will rarely work on NixOS. Of course, the ’nix way’ would be to write your own package and module for it, but that can be a daunting task. Here are some ’escape hatches’ to host some of the simpler services without having to write your own Nix package or module. ...

The other day, I stumbled upon RMK, a keyboard firmware written in Rust. Given that my Ferris Sweep has a Ferris the crab logo on the silkscreen, it felt only fitting that I flash it with RMK. Since I first built it, my Ferris Sweep has been running QMK, a very mature C-based keyboard firmware. QMK is a great project, and doing basic keymaps for an already-supported keyboard is straightforward and well-documented. However if you are designing your own keyboard, or want to use certain advanced QMK features, you wont be able to use QMKs JSON-based ‘data driven’ features. Instead, you will have to use its C macro based configuration, which can be daunting and may require understanding QMKs complex build system. ...

Over the past few years, it seems like the rate at which new CLI tools are being written has picked back up again, accelerating after seeing relatively little activity between ~1995 and ~2015. I’d like to talk about this trend I’ve noticed, where people are rewriting and rethinking staples of the command line interface, why I think this trend might be happening, and why I think this trend is a good thing. ...

I’ve been experimenting with the tools I use on a regular basis lately – switching up my shell, terminal multiplexer, and even trying out other editors. Today, Id like to focus on my experiments with my shell. My old setup Before this, I had been using a minimal zsh setup for a long time, with only built in features and a handmade prompt. Zsh is a good shell, probably one of the best POSIX shells out there, and I still use it when a POSIX shell is needed. ...

I’ve been using a split keyboard at home now for several years (specifically, the UHKv2, though nowadays I probably would have gone for something ortholinear) and I’ve always wanted one for the office. The problem was, if I was going to get a new keyboard, I wanted it to be for both the office and travel, and most prebuilts around are not that portable. I also was not confident enough in my soldering skills to solder the SMT diodes found on many handbuilt designs out there. Eventually though, I stumbled upon the Github page for the Ferris Sweep. ...

I’ve been messing around with embedded rust recently, using the BBC micro:bit as a learning platform. Its really cool to see a high level language achieving the same results as low level c. However, one of my favorite features of rust, the ease of unit testing, is a bit less straightforward to do in cross-compiled, no-std projects. Obviously we cant run tests on our local machine that rely on hardware only found on the target board, but most of a project is going to be logic independent of the hardware its running on. What we really want to do is be able to unit test those independent blocks of logic on our local dev machine. ...

So I’ve been using git to managing my dotfiles since [checks git log]… 2018. At first, I was going to write some inevitably brittle shell script to handle symlinking from the dotfile repo to where each file should be, but before I got about to implementing it, I discovered stow. Now, after using stow for dotfile management for over 5 years, I figure I should really document exactly how I go about managing my dotfiles, with an aim to help other people who want to have an easy to manage dotfiles repo that can be quickly deployed on new machines. ...
