IntroductionThe complexity of graphics APIs, shader frameworks and drivers have increased rapidly during the past decades. The pipeline state object (PSO) explosion has gotten out of hands. How did we end up with 100GB local shader pipeline caches and massive cloud servers to host them? It’s time to start discussing how to cut down the abstractions and the API surface to simplify how we interact w

Introduction to Go 1.21 The latest Go release, version 1.21, arrives six months after Go 1.20. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility; in fact, Go 1.21 improves upon that promise. We expect almost all Go programs to continue to compile and run as before.

Rosetta 2 is remarkably fast when compared to other x86-on-ARM emulators. I’ve spent a little time looking at how it works, out of idle curiosity, and found it to be quite unusual, so I figured I’d put together my notes. My understanding is a bit rough, and is mostly based on reading the ahead-of-time translated code, and making inferences about the runtime from that. Let me know if you have any c

Local-first software: You own your data, in spite of the cloud
Cloud apps like Google Docs and Trello are popular because they enable real-time collaboration with colleagues, and they make it easy for us to access our work from all of our devices.
