Kind of excited to see references to this in the wild!

Do all editors ship with subtly broken defaults as a lowkey test of who can actually make it as a developer?
I just read the book “Longitude” by Dava Sobel and it’s incredible how this seemingly trivial number that I can get to 5 digits of precision in 3 seconds from my phone took the greatest geniuses in history centuries to work out how to compute. Experts are important!

Both of these books are fantastic resources ☺️

What interesting hardware would we build if we could build hardware cheaply enough to serve niche markets? The current design space is constrained by economics (need sufficient volume). But I’m also not sure what hardware would be useful in the world that doesn’t already exist

I’m glad I got into my PhD program when I did. At the time my qualifications were “failed to set my undergrad advisor’s lab on fire (despite some notable efforts)”

I love this idea. (Honestly I kind of want this kind of training environment for humans too, since I have some small organic general intelligences to train)

Hello Anthropic! After 12 awesome years at Meta where I contributed to foundational technology (HHVM, ReDex, PyTorch, Triton) I’ve decided it’s time for a new adventure. I’ve joined the inference team — I’m looking forward to making Claude even faster! 🚀
I am curious: folks who know a lot about parallelism in model scaling, do you mainly get your insights from pencil-and-paper reasoning, from actually running lots of measurements, both? I have a good feel for single-device performance, but not large scale yet

By contrast US culture tends to valorize individual breakthroughs and innovations. I think a healthy synthesis of both perspectives is necessary for progress

I was talking to @tensorbert about why so many Chinese talent on AI especially on the engineering side. It’s because of a deep engineering / implementation/ optimization culture in the STEM education system that favors incrementally a lot more than innovation. DeepSeek was an…
I love @rasbt’s LLMs from scratch - they’re so hackable. A quick optimization project for someone: modify the weight loader so it doesn’t use double memory. I think there’s a way to do it without changing the model FQNs

This is, in fact, a fantastic syllabus for ML perf engineering. Also required, one debugging war story where training loss was just inexplicably too high

getting a phd is mostly about developing a system for maximizing the time you spend in flow state, over several years
Oh no, lots of Perl in gpt-oss. Not sure what this knowledge does to my p(doom) 😅. (My first programming job was Perl! Back in the Mesozoic era)
@shxf0072 @teortaxesTex This is hilarious, the random activation function I made up for this talk because it demonstrated fusion well is actually useful 😂
Prompted by investigations by Boyue Li and @tensorbert, I reduced the kernel launch latency of the open-source compiler github.com/openai/triton by a factor of 7 yesterday, from 105μs to 15μs. Admiral Grace Hopper explains the importance of microseconds in youtu.be/9eyFDBPk4Yw
