Haven’t been on here for over a year but a special exception has to be made to send a huge thanks & to express my sheer admiration of Tessa Barton for creating this work of art & gift wrapping with such TLC (and a chip bow!) (and ofc Adam P. Goucher for such a unique surprise) #gpu #bag

AGI has been achieved internally

it is hard to overstate how much alec radford has contributed to the field, and how much of everyone's current progress traces back to his work. i believe he is a genius at the level of einstein, and also he is one of my favorite people ever--hard to imagine a nicer, warmer, or

Not at all! You can generate and store hashes of all strings within a Levenshtein distance of r of the password and see whether there are collisions between those two radius-r balls, determining whether they’re within a distance of 2r. (r=1 is very practical.)

I've written up what I know about a heavily customised PDP-3 computer built in 1960 by Charles Corderman and collaborators (originally for military applications, and later used for recreational mathematics): cp4space.hatsya.com/2025/03/18/cha…

This was the culmination of a long story! The origins of these ideas came from writing AVX assembly back in 2019 for transposing bitmatrices, and now finally have come to fruition as a general framework for choosing register layouts on SIMD architectures:

Potentially worth stockpiling 4090s: the new Blackwell GPUs don’t natively support single-bit matrix multiply accumulate.

Léo @AltmejdAdam Clive Chan Scott wrote his own SASS assembler so that he could get his matmul kernel to 98% of theoretical throughput (ptxas could only get 70%). github.com/nervanasystems… I learned so much of what I know about writing efficient CUDA from reading Scott’s sgemm walkthrough!

I worked with Sam extensively at DeepMind (for example on arxiv . org / abs / 2105.13343 = multiple augmentations of the same data point in the batch => better & faster training) and this seems like an amazing opportunity to join a great team & mentor at the same time!

We just published "Hash-based signatures for Bitcoin," a new analysis of post-quantum schemes by Mikhail Kudinov and myself at Blockstream Research. This paper serves as a gentle intro to hash-based schemes and explores how to optimize them specifically for application in Bitcoin. 🧵
