   RISC-V assembly tabletop board game (hack your opponent)▲400

   I made this game to teach my daughter how buffer overflows work. I want her to look at programs as things she can change, and make them do whatever she wants. Building your exploit in memory and jumping to it feels so cool. I hope this game teaches kids and programmers (who seem to have forgotten what computers actually are) that its quite fun to mess with programs. We used to have that excitement few years ago, just break into softice and change a branch into a nop and ignore the serial number check, or go to a different game level because this one is too annoying. While working on the game…

   Llama 3.1 70B on a single RTX 3090 via NVMe-to-GPU bypassing the CPU▲395

   Hi everyone, I'm kinda involved in some retrogaming and with some experiments I ran into the following question: "It would be possible to run transformer models bypassing the cpu/ram, connecting the gpu to the nvme?" This is the result of that question itself and some weekend vibecoding (it has the linked library repository in the readme as well), it seems to work, even on consumer gpus, it should work better on professional ones tho

   I built a toy TPU that can do inference and training on the XOR problem▲134

   We wanted to do something very challenging to prove to ourselves that we can do anything we put our mind to. The reasoning for why we chose to build a toy TPU specifically is fairly simple: - Building a chip for ML workloads seemed cool - There was no well-documented open source repo for an ML accelerator that performed both inference and training None of us have real professional experience in hardware design, which, in a way, made the TPU even more appealing since we weren't able to estimate exactly how difficult it would be. As we worked on the initial stages of this project, we…

    Video Commander▲87

    I've been building open-source tools in the video/multimedia space for 10+ years. Finally shipped the commercial product I always wanted to exist — Video Commander, a desktop app that consolidates FFmpeg, ffprobe, MediaInfo, VMAF and more into a single workspace where you can inspect, encode and analyze video. Built with Tauri + Rust backend, React frontend. FFmpeg and VMAF. Not a cool AI/LLM project, just a tool I've been heads-down building over the last six months. Happy to answer any questions!
