  A no_std x86_64 kernel that boots under QEMU, draws its own framebuffer console, and hands you a shell. Built to understand boot, memory, interrupts, and filesystems by writing them.

  Reverse-mode automatic differentiation, broadcasting-aware gradients, convolutions, optimisers, and a trainer, written so the machinery stays readable. 137 tests and a finite-difference gradient checker keep it honest.

  AI / ML, Developer Tools

  An open embedding model reads a repository's issues inside the browser tab and lists the open ones that repeat an earlier report, with the duplicate comment ready to paste. On zed and neovim, which it was never tuned on, the issue maintainers linked was in its top three 65% and 58% of the time, against 38% and 39% for keyword search.

  Reads the camera stream, samples it against a luminance ramp, and paints characters to a canvas every frame. Photo and video capture, adjustable density, and a render-time counter so you can see the cost.

  AI / ML

  Seven apps from four weeks of Hacktoberfest AI challenges, each running an open-weight model in the browser tab, from Whisper and CLIP to Gemma 3 and Kokoro. Nothing is uploaded, and the code around each model does most of the work. In Proof of Grass, adding classes for rooms and screens cut the indoor photos that wrongly filled a bingo square from 29 of 29 to none.

  A GitHub bot that runs a bug report's code in an offline Docker sandbox and labels the issue confirmed, cannot reproduce or invalid from what happens. A local Qwen3 4B only reads the report, and fixed rules got 9 of 11 real closed issues right. Built overnight with three teammates. I owned the extraction, verdict rules, pipeline and CLI.
