I love my Framework 13 and I'm definitely getting one of the new 13 Pros but right now I'm having a lot of fun upgrading this old T480S into the ultimate Linux distro hopper!
I really hope these are also hosted on progressively less standard infra, with the last on a Raspberry Pi and a solar panel talking through a modem downdetector.com downdetectorsdowndetector.com downdetectorsdowndetectorsdowndetector.com downdetectorsdowndetectorsdowndetectorsdowndetector.com
Definitely not me getting distracted from an embedded project then spending weeks building tools for declaratively packing and deploying LittleFS images and all but forgetting the original project I was working on github.com/MerrimanInd/...

Do I know anyone who's worked with LittleFS for embedded devices? I'm writing some Rust tooling for building and deploying it and would appreciate hearing about how others have used it!
I've been in "weird esoteric industry protocol running on RS-232" purgatory for months now. SCPI, VE.Direct, now ProXR. I've implemented them all in Python, some in Rust. I think I have to keep building these until I atone for some kind of sin?
There are three rules of coding with agents: 1. Keep them away from bright sunlight 2. Never get them wet 3. Never feed them after midnight

It's 2026 and I'm not afraid to say it to the whole world. Cancel me if you want, I have to speak my truth. Light mode is good and is the appropriate choice in many times and places.
I just switched my desktop environment from GNOME to COSMIC in minutes. Deleted a dozen lines of text, added a half dozen lines of text, and rebooted. NixOS is absolutely overpowered.
Happy year of the linux desktop (Like every other time this has been said, this post will age wonderfully I'm sure)

Why I'm a Rustacean
The fall and winter of 2025 turned up the volume on the debates around Rust adoption. There have been some high profile successes, some equally high profile missteps, and now technologists who were no...

I happened upon this blog post about why mid-century industrial design uses such interesting color palettes. I LOVE mid-century aesthetics and color palettes like this (inspiration behind the Merriman Industries brand) so this was serious Xander-nip. bethmathews.substack.com/p/why-so-man...

New entry to my Naming Hall of Fame: Electron! Electron was developed by the Atom IDE team and early on they called it 'atom-shell', as in the shell that they ran in. A shell is also the region where electrons can be found in an atom so the project became Electron, an homage to its origin.

Happy Advent of Code 2 years ago AoC was one of the first "real" things I tried to do in Rust and boy was it a slog. Returning to the challenge now is a great showcase of how intuitive the language has become. My stretch this year is doing it all in the terminal with Helix! helix-editor.com
