1. I trained a 44M parameter quantized LLM from scratch on 45B tokens. It ships in 19.8 MB and runs at ~1,900 tok/s on CPU. [P]

Snippet: Three weeks back , i posted SHADOW-250M here. It got 360 upvotes, 293 on r/LocalLLaMA and 94 GitHub stars. Thank you. That model was 60 MB, ran around 400 tok/s on CPU and could retrieve records from an archive on disk. What it couldn’t do reliably was reason over what it retrieved or compute. So I built a smaller one to experiment with those two problems. SHADOW-50M is actually 44M parameters, trained from scratch o…

Snippet: I’ve played some of these before, albeit a very long time ago. But I thought it would be fun to revisit them after playing most of the games that came later. Note, I didn’t do the Master Levels. I completely forgot about them until I’d finished all three, by which point I’d had enough. Final Doom This was a pair of Doom WADs made by third parties in the community, packaged and sold as a single new game. Not exactly a…

Snippet: Hi everyone, Inspired by tools like Chessvision.ai, I wanted to take a different architectural approach and build a browser extension ( ChessInsights AI ) that performs chessboard detection and piece recognition 100% client-side using local inference—with zero image data ever leaving the user's machine, support for detecting multiple boards in a single frame, and entirely free features. The main goal was to bridge pa…

Snippet: Been a lurker here for a bit, so I decided to share my recent build. Still a work in progress so the pics are bit of a mess. Definitely nervous about sharing haha. Went overkill because I wanted to build something unique, experiment with cloud computing /Type-1 Hypervisors, and running LLMs for my upcoming MSCS AI/ML program (fingers crossed I get accepted in to GA TECH 🤞🏾) The first few screens are from my testing…

Bot probability: Low (5%)
Snippet: I have seen a lot of discussion lately about people having multiple checkride failures and wondering if they should keep pursuing a career in aviation. I think the answer deserves a little more nuance than either “never give up” or “you clearly aren’t cut out for this.” If you fail a checkride, pick yourself up and figure out what went wrong. If you fail another one, take an even harder look. At some point, though, y…

Snippet: Hi everyone, I'm Belgian, and my lifelong dream has been to become a pilot. I recently failed the standard colour vision test in Europe (EASA) due to congenital colour blindness, failed the CAD test (21.8), the Beyne lantern, and the Nagel anomaloscope at the military hospital in Belgium. Yet I fly privately and can clearly distinguish PAPI lights and all fundamental aeronautical lights. I'm now looking to Australia,…

I have a Truenas Scale NAS, and I installed Tailscale on it. This was all working well, and I am currently living overseas and accessing the server in my home country via tailscale on my laptop.

Snippet: What concerns me most about quant work, especially pure alpha research, is that there is a directly verifiable reward signal. In principle, one could unleash a swarm of 10K AI agents, similar to what OpenAI did on Navier-Stokes, and have them collectively learn a firm's entire system, coordinate with one another, generate millions of alpha hypotheses, and backtest them in essentially the same way human quants do toda…

My conclusion : If you want a simple and lightweight solution for small clusters to make your data more resilient on kubernetes, Longhorn provides you with all of your basic needs.

Snippet: Working through a data-quality problem that I don't think has a clean answer: a lot of the regulatory data that's genuinely useful for signal-building (13F/13D institutional holdings, XBRL fundamentals, FINRA short interest) is either lagged by weeks, occasionally gets restated after the fact, or is just missing for a given ticker/period with no explanation given.
