@tobi lots of great UIs have been made for profilers (Tracy, Firefox Profiler, Instruments, etc.) ... and now all we want is raw data. CLI for probing and querying perf. Bring back the ASCII!

Autoresearch works even better for optimizing any piece of software. make an auto folder, add program.md and bench script, make a branch and let it rip.

nanochat now trains GPT-2 capability model in just 2 hours on a single 8XH100 node (down from ~3 hours 1 month ago). Getting a lot closer to ~interactive! A bunch of tuning and features (fp8) went in but the biggest difference was a switch of the dataset from FineWeb-edu to NVIDIA ClimbMix (nice work NVIDIA!). I had tried Olmo, FineWeb, DCLM which all led to regressions, ClimbMix worked really well out of the box (to the point that I am slightly suspicious about about goodharting, though reading the paper it seems ~ok). In other news, after trying a few approaches for how to set things up, I now have AI Agents iterating on nanochat automatically, so I'll just leave this running for a while, go relax a bit and enjoy the feeling of post-agi :). Visualized here as an example: 110 changes made over the last ~12 hours, bringing the validation loss so far from 0.862415 down to 0.858039 for a d12 model, at no cost to wall clock time. The agent works on a feature branch, tries out ideas, merges them when they work and iterates. Amusingly, over the last ~2 weeks I almost feel like I've iterated more on the "meta-setup" where I optimize and tune the agent flows even more than the nanochat repo directly.

"The day was January 6th, 2017. A normal day for most, but a very monumental day for 2 very important Roblox developers." Happy 9 year anniversary to the creation of Roblox Jailbreak! 1 more year till 10 years, I wonder what will happen? 👀

Yoo, thanks to everyone who watched my recent video and supported the channel, it was much more attention than what we initially hoped for. 🔥 We’re getting pretty close for The Forge’s release. 24 hours public test gonna be announced soon in our discord server.

Lessons learned designing+building a (mostly) printed jet engine from scratch: - SLM metal prints require substantial post processing to achieve anything close to traditionally machined ones - Low-cost turbine balancing methods are very primitive - 🧵…
Alex Boniske@AlexBoniske

Tentative next steps for early 2026 if we continue: remachine the backup impeller for less pressure leakage,re-test, then build a turbine-burst capable test rig and attempt a run on kerosene

Starting to look like a real chip! Need to pack more logic cells in all that empty space, and then fix some timing issues (which might entail re-arranging the SRAM blocks). But pretty happy so far!

I just completely gutted the Jailbreak Jewelry Store robbery code and recoded it from the ground up for its revamp. It's super cool! And... check out ziplines in Jailbreak!

Went out to support the Piggy Intercity team at RDC! Hopped to multiple mixers at bars at night, and hung out more casually at the mall & breakfast during the day. BSlick did an AMAZING performance that got the whole crowd BUMPIN! @DaRealMiniToon @moonfallx @BSlickComposer
