C23: > The unary * operator denotes indirection. If the operand points to a function, the result is a function designator; if it points to an object, the result is an lvalue designating the object. If the operand has type "pointer t

How does arithmetic work with NonZeroI16 and remain efficient? What's the codegen of adding/subtracting two NonZeroI16 values?

Like one that is free'd or point to a stack object that is no longer in scope. Or one that points one past the last element of an array.

More like: switch (e) { case A: foo(); break; case B: bar(); break; } std::unreachable(); instead of: switch (e) { case A: foo(); break; case B: bar(); break; default: std::un

On libstdc++ std::unreachable() also reliably crashes if you define either _GLIBCXX_DEBUG or _GLIBCXX_ASSERTIONS. libc++ should have a similar macro. I expect MS STL to also reliably crash on debug builds here, as it's quite heavy on d

I recommend omitting the default case and putting std::unreachable() outside the switch and omitting the default label for the sole reason that compilers are more likely to warn for a missed case label this way (-Wswitch vs -Wswitch-enum in

However matmat is done, row-major vs column-major for both matrices shouldn't make a difference (for square matrices at least). I don't know if tiling is done for matvec. I don't think it makes sense there, but I didn't

C code conforming to the ISO C standard generally requires a (very small) runtime.

Even if the RGB components correspond to sRGB, to linearize you apply the same non-linear function to each component value, independently. So even if you do the interpolation in a linear colorspace, the order of the sRGB components does not

Your reasoning starts out nicely with y=Ax, but you get the wrong conclusion. The layout of x and y are not affected at all by row or column order, they are just consecutive numbers in either case. So you have to look at the layout of A. Fo

Technically still better than not offering deletion at all, but of course in reality it's in many ways worse.

The images might have ~10cm resolution, but that doesn't necessarily mean that there can't be larger scale systematic offsets and other distortions for larger tiles. I recently learned that satellite images are often corrected to

Hmm, this opens the possibility to also commit these files as directory structures. I wonder how this would affect merges and conflicts.

If you asked a person to give you a random number between 1 and 6, would you accept if they just said a number they just came up with or would you rather they rolled a die for it?

Switzerland has a lot in my experience. At least the few cities that I visited. They are also very well mapped on openstreetmap, so it was easy to search for a nearby one with osmand whenever I was thirsty.

The "printf" hiding is probably too crude and tailored to bash. But I don't see why the so file couldn't just modify the environment once it's loaded.

Merges of course should have changes, but IMO they shouldn't have changes that are not resolving conflicts (either actual conflicts marked by git, or conflicts that manifest in failing tests, etc...). An entirely unrelated change stuff

Interesting. From what I can find the pixel format is 4 polarization directions per pixel, 45 degrees apart. Even though there are 4 channels this doesn't allow to deduce the V Stokes parameter (this camera can't capture circular

> like 256 orientations per pixel per image You only need 4 parameters to describe the polarization at a single wavelength[1]. Naively this could be 4 parameters per color channel, so 12 channels overall. I think you could potentially ne

For me that means having multiple keys in `authorized_keys` for the same user and never transferring private keys between devices. From what I gathered from the discussion here, this is not a given.

I don't think a fresh boot is the best benchmark for this. I do use plasma and in my experience memory usage tends to go quite a bit higher with use, even if you close everything. I don't think they have leaks and it's probab
