No need for image gen to get this kind of problem; to me that skin look just reads as really aggressive denoising. And there is no escaping physics, a tiny high-res sensor will need a whole lot of denoising for this really challenging sce

It’s partly by design—the word senate shares its root with the word senex “old man” (whence also senile , etc.) because it’s literally a council of elders. That’s what the Roman one was and what the US constitution (among others) was a

Depending on the effort you’re willing to put in, you don’t have to: gzip has a specific provision for concatenated files and tar is a flat array of (file) records each followed by file data, terminated by a sentinel record, so what you nee

Judging by the lowercase “m” it’s the 8x16 variation[1] and not the 9x16 one you linked, but otherwise yes, looks like the plain old VGA font? (Incorrectly displayed, as the site points out: the VGA didn’t have square pixels in either of th

Muratori et al. like comparing speeds to (single-core) memory bandwidth (dozens of GB/s) and that’s a reasonable upper bound, but generally it seems to me that, unless you operate on huge elements and don’t do very much with them, you

Some time ago, I’ve come across an Asahi patch to I think Pipewire that tied system volume to a Macbook-specific loudness compensation filter, but I couldn’t figure out how to actually make use of it outside of their environment.

Kinda. There are also the 32-bit bits on top, not (AFAIU) that different from their NT4 counterparts, such as the shell, COM/OLE2, TrueType, OpenGL, etc.; the core Win16 stuff (KERNEL/USER), which the Win32 layer thunks down to an

Likely 32-bit file access[1] and the caching it included? The arrangement where Windows calls 16-bit MS-DOS entry points to do I/O (including from 32-bit programs) to respect preexisting DOS drivers, network redirectors, etc., but then

It’s not correct to say it was “really 16-bit”, no, but as Unauthorized Windows 95 [1] eloquently demonstrates, neither was Windows 3.1 or 3.11, especially with Win32s, and Windows 95 was much more of a direct descendant of that environmen

Nixpkgs has 11k open PRs at the moment (a lot of them routine version bumps and such), so no. But then Nixpkgs isn’t a piece of software in the conventional sense: the monorepo does contain a few of those, but most of it is a giant collecti

Less of a commodity at this point than a few years ago, what with Minio immolating itself to be reborn as, excuse my French, AIStor. Which is not to say that TFA’s approach is invalid or uninteresting, but the mechanics of how “an S3” works

I don’t imagine that you’re unaware of any of this, but: ld.so and libc.so are heavily interdependent in deliberately undocumented ways with Glibc and outright the same file with shared Musl. And while you might usually get away with using

IIRC the only Frameworks that have a coin cell in them are the 13-inch 11th-gen Intel ones (i.e. the OG model), and it should be right there staring you in the face as you lift the keyboard. There’s indeed a known design flaw[1] around that

C++ bundles together a way to write functions inline in an expression (what I’d call “lambdas” in general) and a way to create closures with strictly nested lifetimes, but there’s no law of nature tying the two together. Even in C++ the ess

Good C style is that every function that accepts a callback should also accept an opaque context pointer it then passes through unchanged to the callback. Usually the caller will allocate a structure on the stack or the heap, stash some of
