Looks like angle sum identity. cos(x+y) = cos(x)*cos(y) - sin(x)*sin(y) (always) ~ cos(x)*1 - sin(x)*y (if y small) Can't speak for the validity of small angle assumptions though.

Polynomials with the coefficients defined in the sin and cos arrays (and likely in the referenced literature).

It's an easy way to return nan and set FE_INVALID. If you're not worried about floating point exceptions you can just return NaN directly. Idk how much C# even guarantees about the…

>Certainly do not use finite-math-only when dealing with external data. so... never?

Because the danger of fume is negligible. It's a thing if you put it in a 2m^2 storeroom and sniff the exhaust for 8 hours straight but in any other case it doesn't come close to c…

In isolation, no. You could instead spend your time optimizing something else that's currently slower and speed that up instead.

The compiler is not beholden to the standard library but the standard. So all modern compilers come with a bit of knowledge of how standard library functions like memcpy are suppos…

I think he has that correct. Ime it's split on east/north vs. north/east but wgs84 is very dominant with lat/lon.

And how much more do they cost in comparison with hooking a few copper wires to a simple copper plug manufactured in china?

It is useful with some badly written build systems that think they have to write every invocation of gcc to stdout. Like every badly written Makefile out there. Or `cat myapp/log/y…

Maybe, maybe not. Is the potential benefit even worth fighting over? Style is just full of so many subjective details that every discussion ends in. And everybody has their favorit…

On the other hand I understand de data model of git and can't to the most basic shit without looking up which invocation I need via search engine/man pages. Like... deleting a bran…

But if we get rid of a whole class of bugs and vulnerabilities, the number of bugs will go down, no?

>Do I really know how much cycles/stack it takes to do std::sort(a.begin(), a.end()); in that specific platform? No, so I cannot trust it. I also don't know how many cycles it take…

Rust in general will panic on memory allocation failure. There was some discussion about oom handling a while back but I don't know the current state.

Competence doesn't seem to be a requirement in these positions.

Apparently it's mostly a "when". https://twitter.com/kylealden/status/1115307632124780545

Which makes it a different function `assign_invert(x) = assign(invert(x))`
