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.

Bot probability: Low (28%)
Snippet: I built tapflow for teams that need to check mobile builds but do not want every tester to install Xcode or Android Studio. The topology is worth stating first: the relay can run on Linux or Docker, while the agent that drives the devices must run on a Mac. Apple only provides the iOS simulator on macOS. The Mac agent makes outbound WebSocket connections to the relay, so the agent side does not need an inbound firewa…

Snippet: We get questions in the AOPA Pilot Information Center from pilots with private or higher certificates who want to fly while exercising sport pilot privileges. The rules can be a little confusing, so here's the shortened version. Under 14 CFR § 61.303 , a higher-certificated pilot can act as PIC while exercising sport pilot privileges, provided they're appropriately rated and otherwise qualified for the aircraft and c…

Snippet: After loosing data a few times through sheer stupidity, I decided to give Longhorn a try. 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.

Context We have six internal teams, and they could grow, each with their own AWS account, logs, and metrics. Our previous generation ran the entire stack on ECS (one dedicated stack per team), and it got expensive. However, the bill turned out to be an issue of sizing rather than topolog…
