Although it references CUDA and general purpose GPU programming applications (and relevant terminology), this is an interesting collection of GPU optimisation techniques in the literature. hgpu.org/?p=28413

I made a thing. It's been done for a long time and I just wasn't brave enough to press the big green button. The game is an acquired taste and I'm pretty sure most people shouldn't buy it, but if it still sounds like your thing, give it a go. (Or don't.) store.steampowered.com/app/1…

I remember reading about determinants in high school. The name was scary and not much context was given. 😦 For a long time, a determinant was just a value I had to blindly compute using a formula. Here's what I would like to know about determinants when I first started... 🧵

Nice little O(1) GPU memory allocator thread from Sebbbi. I'm a big popcnt() and leading/trailing zeros count fan myself. Always nice to see their values extolled :-) . Bit tricks FTW.
Let's design a fast O(1) memory allocator with minimal fragmentation. Need to sub-allocate GPU resources (Metal placement heaps and Vulkan memories), so we need a good allocator. Thread...

Soil liquefaction occurs when a cohesionless saturated/partially saturated soil loses strength when responding to stress such as shaking during an earthquake, and behaves like a viscous liquid Here you can see the effects with different foundations 1/🧵

A Netflix user will browse the app for 90 seconds and leave if they find nothing. Thumbnail artwork is actually NFLX's most effective lever to influence a viewer's choice. A user will look at one for only 1.8 seconds, so NFLX spends huge to optimize them. Here's a breakdown🧵
