In Vim, the "stupid" auto complete will get 80% of the way there and works without setting up a language server and it works for any language. By default it will give all the identifiers in all open files. Having a few of the rele

Why does adding `backtrace` to thiserror/anyhow require adding debug symbols? You'll certainly need it if you want to have human readable source code locations, but doesn't it work with addresses only? Can't you split of

On an embedded system out in the field? Depends on the use. On your prototype devkit? Absolutely.

I will respectfully disagree with your statement, with the caveat that I mostly dabble in arithmetic with 128b/256b float and int vectors. Using C or C++ with vector extensions (Gcc/Clang) or Rust (nightly) std::simd is very easy

I have a similar technique before, embedding the entire font data in the fragment shader source code. Then you can use `snprintf` to directly print into a GPU buffer mapped to the CPU (this is a footgun, I know). Instead of drawing individu

This statement isn't true at all. There are tons of fixed function hardware units for graphics in GPUs in addition to compute cores: triangle rasterizers, texture units, raytracing units, blitters, copy engines, video codecs, etc. They

I have an even better darn grid shader that I use in my graphics projects. The shader in this article wants to emulate the look of a sampled texture so that it blurs to medium gray at distance while avoiding moire patterns. And it does inde

Absolutely, look into your standard library, CPU built-ins and intrinsics first. However, these tricks are not useless even on modern CPUs. There are scalar instructions for a lot of this stuff, but if you are working with SIMD, several of

I have to agree with the author that battery powered chain saws are not for heavy forestry work. But for a homeowner's odd chain saw jobs they beat gas powered chain saws hands down. Particularly if the use is infrequent, it starts whe

Yes, radix sort can sort integers in linear O(N) time.
142.
by exDM69 2y ago
Problem with radix sorting strings is that it is O(k*N) where k is length of key, in this case it's the second longest string's length. Additional problems arise if you are dealing with null terminated strings and do not have the

They are very similar, but wgsl is its own language. Vulkan can run SPIR-V shaders written in glsl, hlsl or slang. Other experimental languages exist (like rust-gpu). Wgpu is a bit behind on GPU features, for example they've added supp

I've done some compute shaders with Vulkan (and a lot of graphics shaders). It's quite nice and simple, after you have gone through the initial hurdle of setting it up (or used a helper library to do it for you). For compute shade

Games do a very impressive amount of work for graphics but there's a huge difference: a dropped/late graphics frame every now and then is not a big deal. An audio glitch is very annoying by comparison, especially if the applicatio

You need to remember that when TrueType fonts were introduced, a typical display resolution was 640x480 to 800x600 on a 13-15" display. If you rasterize the Bezier curve outline of a ttf font at that resolution, you will have very croo

In addition to the missing newlines, the inline assembly code is also not correctly marking that it clobbers memory. It is probably not an issue for the entry point function, but the lack of it could mean the compiler is allowed to do incor
