> the average over the whole day was 49.975Hz which doesn't strike me as particularly bad. A day, having 86_400 seconds in it, is equivalent to 4_320_000 pulses at 50 Hz. At 49.975 Hz, it's only 4_317_840 pulses which is 2_160

The example in 1.13 probably would work better if the example with scalar instructions actually had, you know, more instructions than the one with the vector instructions. Otherwise, it's very taxing to read things like "static in

Yeah, except you don't need to rewrite that code every time a new AVX drops, and also don't need to bother to figure out what to do on older CPUs. IIRC libc for x64 has several implementations of memcpy/memmov/strlen&#x2

Not to mention that Rust too had "let's have the minimalistic stdlib for now, let the community figure out the rest" approach and the results are somewhat mixed.

It... really does look like it uses slightly modified Minecraft textures for blocks. No, seriously, it does look that way.

There, apparently, were quite a number of ISAs where checking the sign bit was more convenient (performant?) than checking (in)equality with zero.

Yeah, but it's a shame that almost every language gets it wrong (and even traditional presentation of mathematical logic) and uses zero as representation of FALSE. It should represent TRUE!

Not really, no. Newer versions of standard can (and do, although rarely, I have give it to C standard committee) introduce incompatibilities with earlier versions of standard. E.g. at one point the standard explicitly allowed to #undef &quo

I've asked you why prepending paths to PATH instead of appending was a bad idea. How is having typing full paths has anything to do with it?

But everything after headers can (almost) be a blob. Just copy buffers while taking care to track CRLF and look if what follows is a space. In fact, you have to do it anyhow, because line-folding is allowed in headers as well! And this &quo

I am willing to bet the whole xAI/SpaceX merger is simply a ploy by Musk to evade releasing accurate historical information about SpaceX's finances. How much did it actually cost SpaceX to launch a kilogram of payload into space

It's pseudocode. A mix of Python's block structure, C's style of variable introduction, and Pascal's use of ":=" for assignment and "=" for equality. Oh, and assigning to output variables instead of e

And having a CPU with "128-by-64" or "64-by-32" division instruction (such as x86/x64) simplifies the algorithm even further. Inputs: uint[128] N, uint[128] D Outputs: uint[128] Q, uint[128] R such

Since they don't calculate the upper 128-bits of the product, they use only 3 multiplications anyway.
