@szeloof it's important to have fun

Software should be fun and fast

if you're into things like eventual consistency, computational geometry, combinatorial optimization, high throughput networking, circuit design, intelligent tools, UX, novel visualizations-- reach out :)

@Roblox @NosniyRBLX freaking sweet profile. Awesome game, awesome devs 👑

Meet @NosniyRBLX, the dev behind the success of RIVALS.

@atomic_semi 👍👍

We do demos every week at Atomic Semi, we’ll start show you some on here too

@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.

@ContextLostRBX want to come work on computational geometry for chip fabrication @atomic_semi? Come tour our lab

Last week at Roblox. Time for something different. Just don't know what yet.

@karpathy Operation Vacation :)

ah yes, this is what post-agi feels like :) i didn't touch anything. brb sauna

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.

Advice is most trustworthy when it goes against the advisor’s incentives

@cslorer @henrl @szeloof 👨‍🍳 send us something fun you made, that’s all it takes

you can just dm me if you want a job. im serious. you can work with @henrl and @szeloof and @badccvoid

@SondreMOTE @JMCgaming24 @badimo @asimo3089 HAHA

@JMCgaming24 @badimo @badccvoid @asimo3089 @badccvoid I think we found where the Roblox trivia Kahoot got its wrong release date from... 😅

"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? 👀

@patrickc Really great initiative

A Call for New Aesthetics: newaesthetics.art.

@FireAtacck Love this video! congrats on making a great piece of art :)

If you haven’t seen the video yet. Here’s the link for it: youtu.be/_oTjuC2XvmM

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. Discord.gg/theforgers #roblox #robloxdev #theforge

@barr73647 what’s your favorite weld

@badccvoid My home state

Longhorns.

@BeastyBlake101 Yes

@badccvoid Texas?

@AlexBoniske Cool

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 - 🧵…

@splinedrive @BreakingTaps How many cells are in this?

@BreakingTaps @BreakingTaps lmao

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!

@REAL_EpicTank Zip lines are SO FUN

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!

@MaximumADHD Wow

Spotted at a random Salvation Army thrift store in northern Illinois

@sleitnick I love this concept hahaha

The new crane generator makes this so much better
