#592working hard at https://simstack.io, a "flight simulator" for engineers to practice hard, production engineering skills.
the idea is to give engineers a playground full of interesting challenges to test themselves against. I've also been [running ai agents on them to see how they perform](https://youtu.be/EXGOJcMJ2pU)

#594I'm finally getting my online presence in order... This week, I'll set up a Hugo blog with the Ed theme, love it, looks exactly what I'm looking for, and as a former LaTeX enthusiast, it's pretty close. It's readable, minimalist. I'll need to customize the theme, though. I plan to publish blog posts about anything I find interesting. https://gohugo-theme-ed.netlify.app/ In parallel to this work, I'm setting up a simp…

#597Not as exciting or big as some of the projects on here, but just a small personal one I’ve been wanting to do for a while. I recently impulse bought an Epson receipt printer, and I’ve started putting together a server in Go to print a morning update every day. Getting it to print the weather, my calendar and todos, news headlines, HN front page. Basically everything I pick up my phone for in the morning, to be on pap…

Crystal is a re-imagining of what an IDE means when AI drives development. Traditional IDEs are designed for deep focus on one task at a time, but that falls apart when you have to wait 10-20 minutes for an agentic task to run. Crystal lets you manage multiple instances of Claude Code so you can inspect/test the results of one while waiting for the others to finish.

#599This weekend, my modified Android/mobile Point of Sale (POS) app was used to celebrate the 100th anniversary of our village's volunteer firefighting organization. The standard fiscal POS app was adapted to support a sort of low-trust swarm of waiters who used the app to collect orders. These orders were then transferred to a few high-trust cashiers by scanning QR codes generated on the waiters' apps. After receiving…

#600I'm dealing with mime types and max file sizes for an uploader, and improving error messages. Instead of relying on the file name to detect the mime type, I'm using the file binary header instead to reject dodgy files (for ex a `sample.jpg` file that is actually a ZIP or EXE under the hood).
