Or more generally bounding volume hierarchies, of which AABB trees are a subset. They’re great. Good perf, while being one of the simpler ways of accelerating spatial queries (compared to other types of trees, at least)

The term you’re looking for is speculation, not specialization, but no, I don’t think it does either. C++ and other languages targeting WASM often do type specialization, but it’s entirely done before the browser sees WASM, and has nothing

You should be able to import your history from chrome, and then use firefox sync. Or am I misunderstanding what you're looking for?

I've also (recently) had poor performance on MSVC when "outside the loop" meant "a function argument", for a type that was essentially a struct wrapping a single primitive. It ended up being ABI weirdness that was c

Eh, this kind of knowledge can absolutely be beneficial when debugging. It won’t help you structure a program though.

Declaring a primitive variable inside vs outside a loop in c or c++ will have no effect when compiled with optimizations on by any major compiler. For non-primitive types it will depend on a number of factors, and the better choice for perf

If they’re suggesting better or even equivalent ways, I just do it. If you are not sure, also just do it? Life’s too short to be arguing about every code review comment. The only time I argue about review comments is if i think it wont work

Not including the struct in the header defeats the ability of the user to control where the type is allocated in memory, among other things. That’s a feature that many c programmers are willing to give up a certain degree of api/abi co

I did something fairly similar to this here: https://codepen.io/thomcc/pen/vLzyPY (I need to look into why this isn't running at 60fps anymore on my laptop, it certainly used to...) The big difference is that

JS is the only one of those that has dynamic typing, at least by the conventional meaning of the term.

Yeah, more or less, but a project this size (small) would really bear those differences out, I think. In particular, resource binding is very different between Metal and Vulkan. Metal's resource binding is more simple/traditional.

Name resolution is already so insanely complicated in C++ it's hard for me to lament this too much.

Clean room is a defense against copyright and not patent, AIUI. For patents it doesn't matter if you knew someone had patented it. Not a lawyer, though, but a quick search confirms this.

IME most of it is due to how bad c++'s builtin allocator support is though. C++11 helps a little but a lot of stuff you might want to do seemed to be impossible last time I looked. This is awful since games will often use pools and are

I wouldn't assume so unless you're comparing against a fairly naive JS implementation. Copying strings between JS and asm.js/wasm is slow, so there's additional overhead just calling back and forth. Reading through the C

IME a more common case is overengineering. Not only does this slow someone down initially, but the extra complexity often continues to slow them (and anybody else in the same codebase) into the future.

This isn't the issue I'm describing at all. E.g. if I missed a bounds check, and access past the end of a `Foo[]`, it would be typed as `Foo` (and not `Foo | undefined`), but really be `undefined. Consider this code. var f

> Strict null-checking eliminates the dreaded null-pointer exception When I was using typescript this still came up if you missed an array bounds check, you'd end up with an unexpected undefined. Pretty annoying and tough to debug.

It's a common example for a patent that had a lot of prior art but was granted anyway. I don't know enough about patents to say if there was a reason the prior art didn't apply, but I know that Namco was fairly protective of

Windows' stack is still a ways from being reliable in a lot of somewhat important cases like (real) fullscreen, but it's certainly miles beyond X11 and Linux. (I don't have enough experience with Mac's to speak to it).
