We must pace the frontier
I have worked on AI for the last twelve years because I believe it could dramatically raise the quality of human life. I’ve written often about these incredible benefits: I believe that AI could cure most major diseases in the next 5–10 years, greatly accelerate economic growth rates, create a world of abundance and…

A few good ideas in programming languages
Crystal is a compiled programming langauge with static type-checking with syntax very similar to the Ruby programming language .

The ANE's architecture was too opinionated to build a…

The Deathray: A simple way for an untrusted site to freeze a Mac
A WebGPU shader on an untrusted site can hang a Mac's graphics, making the desktop UI unusable until a restart is forced. All the victim needs to do is click a link. This issue reproduces cross-browser on MacOS, but not other OSes.

Getting 50 GB/S Back from the Apple Neural Engine
An RTL performance erratum in the Apple M3 Neural Engine throttles DRAM weight streaming throughput down to 17–19 GB/s from the nominal 45–60 GB/s, whenever the total weight size is an integer multiple of 1 MiB, which currently affects 7 of ANEMLL ’s 15 models. Avoiding the problematic path in the kernel DMA engine's…
