Show HN: Mini-AGI – Dynamic continual learning model trained on 8GB VRAM

Sorry for the pretentious name, I know, I know.. It just contains all the pieces I would like to see a AGI model to have, and I can't stand the temptation. Before throwing rocks at me, please take a glance at the Readme, and I hope it will cover your mood a little bit. So, first of all it does work

Show HN: Swarm, an offline family tree app for macOS

Hi HN! My wife and I got deep into our family genealogy and wanted to map out all our relatives - but keep the data on our own Macs instead of uploading it to a genealogy service. Nothing we found did that, so we built Swarm, a native macOS app in Swift. It's built on GEDCOM 5.5.

Show HN: Bailout – The coding agent meant to be deleted

hey hn, i made bailout for a pretty specific problem. you boot a fresh vm and want an agent to help get it set up, except you dont have your agent set up yet. no gh, no config, no api key handy. might not even have codex / claude code / opencode curled and loaded. or you already

Run Jev-style typed decisions locally on Apple Silicon

I built Laya MPS, a PyTorch runtime for running Jev-style typed decisions locally on Apple Silicon GitHub repo: https://github.com/afshinm/laya-mps On an M5 Pro: - Default mode: ~32 ms latency, ~2.1 GB peak process RAM - Lowest-memory mode: ~171 ms latency, ~0.74 GB peak process
