Forged in the heart of a mountain.
Less than a month left until the Free and Open Source Software Developers’ European Meeting (FOSDEM)!
With over 900 events already announced, here's my little companion web app that works on desktop and can be installed on mobile to help you with the planning: https://fosdem.sojourner.rocks/2026
New features this year (more improvement suggestions welcome):
- Speaker biographies (click on the person's name or visit the speakers page).
- Bookmark export.
ok, I think I'm done with this project?
it now plays conway's game of life and creepy noises, all from a single STM32G431 MCU with minimal external components, which is really all you can want from some lowfi analogue TV stuff.
In the process of making the audio work I ended up changing from channel 2 to channel 3 to get rid of the interference from the 48MHz clock I use for audio, which also means I'm running the CPU faster and get a little bit more processing time. Number of external components is now 4 resistors for mixing the baseband video signal and 5.5MHz audio carrier. Unfortunately going to the higher frequency also meant losing some signal quality, since I'm operating the internal opamp even more out of spec. Or maybe I'm just unlucky and there is more interference on that frequency here.
Join us at @tog Hackerspace for a hands-on afternoon of mending and repair. Bring your broken bits - and our amazing team of fixers will help you give them new life.

@concretedog Yes, but better. It fixes the 2 main Jupyter problems. Notebooks are fully reproducible and have no hidden state, and notebooks are pure Python code and play well with Git.
@concretedog Right now I'm also looking into Conan for C/C++ package management. Students will have a cross-platform, reproducible toolchain that allows them to automatically create software bills of materials.
That's the boon and bane of OSS, you never stop learning about ever better tools. Every year I teach my software engineering class, I update about 20-30% of the content.
@concretedog I think you could name anything academics do and find open source works better, but maybe I'm in a happy bubble!
It's definitely true in assessment. Commercial systems are expensive, limited and hard to work around when they go wrong. There are lots of widely-used, good, open-source assessment systems. The Moodle Quiz and associated plugins is I think the most popular example.
In my field, maths, there's STACK (https://stack-assessment.org/) and the thing I work on, @numbas.
Because they don't have to track users or depend on a central service, they can be hugely more robust and resilient.
