LLVM 22.1.0 is out! This release was handled by new Release Manager Cullen Rhodes who I have had the privilege to mentor through this process. He did a fantastic job. Go checkout the release notes: discourse.llvm.org/t/llvm-22-1-...

@skillup.bsky.social hey. Just a quick shoutout, I heard your MacroFactor ad around 3 months ago, I was already trying to lose weight at that point, but your ad had me check it out and it has been a god send. I have been on a cut for 100 days and just reached my goal, around -20kg. Thanks!

What a day! First day with the fine folks at @larianstudios.com - the todo list is enormous, but the people is so welcoming and positive. This is going to be great. After that full day of data inhalation I went out for dinner with @kbeyls.bsky.social and it was nice to nerd out with a fellow LLVMer!

Weight loss is very individual, but here is what helped me lose 18kg over the last 6 months. I used the app "MacroFactor" to log what I eat, I replaced my lunch with a meal shake, I focused on my protein intake, gym 3x/week and 10k steps the other days. Motivation is the key, and I had it.
Graph of my trend weight going down 17.8kg.

Job update: I am leaving Ubisoft at the end of the year. I am very proud of the work I did on compiler optimizations on AC: Shadows and I will miss my co-workers there dearly. In the new year I will join the fine folks over at @larianstudios.com and work on compilers and builds. I am very excited!

I worked quite a bit on the toolchain stuff for this, hitting a consistent 30FPS was a hugely collaborative endeavour between toolchain, rendering and other engine work. It's the first time we ship a game with CSPGO as well, which helped in dense areas. Hope you enjoy! youtu.be/3oTfnzXb8OE?...

This is an insane thing to write about game development. www.nytimes.com/2025/07/28/a...

Most experts acknowledge that a takeover by artificial intelligence is coming for the video game industry within the next five years, and executives have already started preparing to restructure their companies in anticipation.
After all, it was one of the first sectors to deploy A.I. programming in the 1980s, with the four ghosts who chase Pac-Man each responding differently to the player's real-time movements.

PSA: If you are playing FF7Rebirth on PC and have texture problems and soft-locks - try upgrading the DirectStorage DLL's. It fixed almost ALL my issues with textures. It's almost like they shipped the wrong version of the DLLs. Hope SquareEnix fix it in a patch soon.

Back in 2021, PMG reported on the unseen games industry crunch taking place at outsourcing studios in SE Asia. Since then, the companies we looked at have continued to work on some of the biggest games in the world, without any push to improve the conditions of the artists doing that work. (1/7)

Very happy to have landed some really aggressive optimizations for an upcoming game today. ThinLTO with whole-program-vtables plus PGO and the basic block reordering. Ended up gaining around 10% performance on the CPU frame on PC. It's been a long road with testing and iteration.
