Hello, I'm Maneshwar. I'm building git-lrc, a Micro AI code reviewer that runs on every commit. It is free and source-available on Github. Star Us to help devs discover the project. Do give it a try and share your feedback for improving the product. I remember the first time the GIL ruined my evening. I was working on FreeDevTools and had a script that needed to parse, validate, and rewrite metadata for a few hundred thousand small markdown files and finally stores it into sqlite DB. The bulk of my work was pure Python, a lot of looping, dictionary lookups, string concatenation, and small object churn. No NumPy, no Pillow, no native libraries doing the heavy lifting. The single-threaded version was going to take forever, so I did what any reasonable person would do, I threw threads at it. Eight worker threads. Should be a lot faster, right? It was the same speed. Maybe a hair slower. I stared at the terminal for a solid minute thinking I'd done something wrong. I had not done something wrong.…
