Jex 1.0, Part 4: The Rewrite
The reasoning gate closes by its own receipts, the board moves to edition 0.3, and the frozen stack is rebased and pushed lever by lever to 60.29: the best of all no-training entries, and the measured ceiling.
Jex 1.0, Part 3: The Audit Tax
The one speedup the audit allowed, and the parity work that paid for it: Route B, batch invariance, and the 55-minute dry run that turned a projection into a schedule.
Jex 1.0, Part 2: The Gate
A gate curve that promised +20 index, a latency wall at 40% coverage, and a pilot built to catch us fooling ourselves: the reasoning hypothesis, measured under a ten-euro cap.
Jex 1.0, Part 1: The Frozen Engine

While researching the subject, I couldn’t find a proper comparison of the three top models. The data for each one is available independently, but no overview is. I asked an LLM to write me a report on the situation, and I thought it would be helpful for others if I posted it here: The frontier … Read more
Debugging iOS Safari from Linux
While implementing Apple Pay on the Bixoto checkout, a collegue of mine was struggling with strange errors on iOS, but couldn’t properly debug it from their Linux computer. Thankfully, it’s possible to get the debugger to work on Linux, although the experience is not exactly smooth. The commands used in this guide are for Ubuntu … Read more
Upgrade Mattermost Enterprise Edition to Team Edition
Mattermost was created as a free and open-source alternative to Slack, but over the years they also added an “Enterprise” paid version, with more features. It can be a bit confusing, because the free and open-source version is called “Team Edition”, but the Enterprise one also has a free plan. Mattermost makes it very easy … Read more
