Cjam – a modern MP3 file editor
Cjam is an MP3 editing and playback tool for Windows. The MP3 format itself has been stable for decades, but advances in CPU power and memory have shifted the relationship between files and hardware, creating room for new approaches to working with MP3s. Cjam provides both a GUI and scripting interface that allow you to process large numbers of files at the frame level. This improves on existing tools, offering faster and more flexible editing and playback.
Cjam – a modern MP3 file editor launched on October 7, 2025 with 5 votes and more than 75% of that year's launches. The site was still online in September 2026, 1 year on.

Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Autism Simulator▲779Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible).

That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
