It could be misinterpreted as a user literal [1], for example with 0xAAAA_BBBB it is unclear whether _BBBB is a user literal. The original proposal discusses some of the alternatives [2]. [1] https://en.cppreference.com/w&#x

Aside from the reasons mentioned by other comments, dev kits include a ton of IO for debugging (multiple ethernet ports, video outs, etc), as well as more memory and storage. IIRC the Wii devkit used an FPGA for the IO controller, and the d

Syntax discussions are hardly ever productive but the `vec4<f32>` syntax is truly awful in shaders. HLSL solved this ages ago with `float4`, `int4`. And even GLSL which uses `vec4` to mean float makes sense given you are almost always

Tokenizing by storing strings in a vector is almost never what you want for high performance code, as it will result in an allocation for each token. If you can keep the original source string around, consider using std::vector<std::stri

I don’t know much about Julia, why would it potentially cause allocations?

operator[] is not only used for lookups though, it’s also used for insertions: m["nonexistent"] = 1; This would not work if you return a dummy value.

If you try to implement your own map you’ll naturally end up with this quirk. operator[] returns a reference to a slot in the map which can be read from or assigned to. Since the reference must be valid, you better have allocated a slot in

Did you read the article? MSVC compiles twice as fast as clang and has double the perf in debug builds. LLVM has an amazing optimizer but the compiler is just so much slower even on unoptimized builds.

The reason is header files. If you do `using namespace std::something` in one file and it gets included in another, the other file now has std::something in the global namespace which it may not have excepted. Other languages like Java have

I would say Mantle jump started the new generation of GPU APIs. Not sure if it predates Metal’s development.

The literal matches are useful in an editor search context where most of the time you want to search for the literal string.

Factorio is a great example of a game that benefits from having a custom engine. For comparison, Cities Skylines (Unity) becomes CPU bottlenecked with a large enough population. Making large cities practically unplayable even on the most po

Unity is still written in C++. It's fairly common to write the core engine in C++ and use a language like Lua, or as is more common in AAA, some proprietary scripting language for gameplay code.

I don't think it's a cultural issue. The difference is you only have to download a game once from the store compared to downloading 10GB+ every time you load the webpage.

Any reason for making delay_ms a template parameter? A compiler should be able to optimize passing a constant as a regular function argument. And if it’s not optimized I assume a variable delay wouldn’t affect much?

I get that, but Bone Labs is developed by a small indie studio. It's hard to believe Meta can't make a decent looking VR experience with the amount of resources they have available. Point is, the hardware is clearly capable and is
