I'm having Claude port a 4000-line rocq proof I wrote from nat to Z. it seems competent

#badprogrammingadvice every python method you don't need can implicitly function as a bool, as functions are truthy and self.method = False shadows the method

my hope was that I could skip writing my own renderer for rich-text tweets but it turns out nitter doesn't actually implement those. still a good exercise

I've been playing with the idea of using nitter as a frontend for my local twitter archive. instead of my own API I have to implement twitter's graphql one for this to work. first time I've touched nim code ever

strange thing I just realized: when all phi arguments in a loop header are defined outside of the loop and loop conditions are not influenced by side effects, then the number of iterations is at most the number of header predecessors

Nanite Tessellation Nanite Tessellation, aka Nanite Dynamic Tessellation, aka Nanite Dynamic Displacement was the next major feature I worked on after Nanite it...

I'm finally writing up how Nanite Tessellation works. The first few blogs posts are up. More will be coming.

what an unfortunate day to be experiencing complex microarchitectual conditions

example gaboronoi

Assuming uniform weights and frequencies, and random colors and anisotropy directions, this is what an example gaboronoi diagram would look like.

Learned of a nasty DX9 gotcha I was previously unaware of: when using the Shader Model 2.0, the fog is still applied by the fixed-function pipeline, but with Shader Model 3.0, it's not! This "broke" rendering when I downgraded a few shaders from 3.0 to 2.0 for compatibility.

like i guess the strat would be to use these guys as human shields basically--blockade taiwan, put up the great fishing boat barrier, dare anyone to run it--and then if you do fire on the fishing boats, "that's an unprovoked attack on civilians how dare you!!!!"

Me reverse engineering: Haha fuck yeah!!! Yes!!

Me engineering: Well this fucking sucks. What the fuck.

doesn’t every approximation times a high enough integer eventually drift into a different quadrant?

A teaser figure showing the process of metamers rendered differentially (MRD). Target scene parameters are used to render a target scene. A new scene is initialized from some starting point, and renders are created from this scene. The loss between the initial and target scenes is measured. MRD allows the gradients wrt the loss to be propagated to the scene parameters (e.g. lighting, geometry or material) for gradient-based optimization.

Legit super excited about this work coming out. My amazing doctoral student @ben.graphics has been working on an idea to use physically based differentiable rendering (PBDR) to probe visual understanding. Here, we generate physically-grounded metamers for vision models. 1/4

For today's Eldritch 2 devlog, I wrote a bit about my in-game level editor and the process of building dungeon rooms. Including drawing navmesh by hand, for reasons!

The Cost Of a Closure in C I had a vague idea that closures could have a variety of performance implications; I did not believe that so many of the chosen and potential designs for C and C++ extensions ones, however, were so…

As it turns out? Not all closures have the same design.

It means they all don't perform the same under various usages, either! A quick dive into the performance differences of Closures in C, using an old Donald Knuth program.

Free my memory? But some of those allocations were real classics. I can't just discard them like that.

a few years ago I was profiling performance on a 64(?) core machine that was far below expected and traced it back to pages being zeroed on demand. I’m not sure what I did after though

Everyone is laughing at you in the group chat man. They're saying you don't even formally verify your code
