No. The bottleneck for me is not the speed at which I type code, which is basically what LLMs accelerate. I've been thinking about trying again, but at this point the context windows are FAR too small to feed my entire project too, a

Voxel engines are interesting because they're very much an area of active research. People are often coming up with novel techniques, and adapting traditional techniques in interesting ways. There isn't any good, singular resour

Hah, thanks for the kind words <3 In all seriousness, I think I have the same propensity to have a hundred unfinished projects and have a hard time finding motivation to complete them. The difference might be that I have this 'big&

I've been working on a 3D voxel-based game engine for like 10 years in my spare time. The most recent big job has been to port the world gen and editor to the GPU, which has had some pretty cute knock-on effects. The most interesting i

How would you preempt the running program during malloc? Isn't there a well-defined reload point? Major red flags going up if your program can just change at any random point.. Also, didn't the article say explicitly that struct

Strong agree here. The 'purity' BS of not modifying the running programs address space appears to come at the cost of significant programmer pain-in-the-ass. Having to hand-hold the library to maintain the indirection table is a

Agreed, debugging tools for the browser are almost comically incapable, to the point of not even useful in most cases.

I think it's actually possible to win on the second guess with any initial input. Or at least I did it a handful of times..

According to the article, the plaster changes properties based on the crack it's currently filling, which is the whole problem.

That's a cool idea, and seems technically satisfying to work on. Well done!

Finally finished the fourth part in a blog series I wrote about SIMD-optimizing Perlin noise. Accidentally wrote what I believe to be the fastest AVX2 implementation to date.

I've always wondered why more languages don't do this. It just makes sense

On a second skim it is nice that errors are surfaced at compile time, but honestly I'm not sure that's worth the complexity.

Honestly, I prefer the long-form first-cut that he dismisses to save 10 lines of code at the cost of using generics.

I have a feeling it might be because the dot product of two unit length vectors is equal to the cosine of the angle between them.. but that's just a wild guess

So (2) in this case would be the scalar version of the function that takes a starting pointer, row stride, channel stride, and a row_length and channel_length. By setting the strides to 1 and lengths to max you effectively tell that functi
