Knowing little about zig, std.mem.eql very likely already uses SIMD. This is about using SIMD to avoid even calling std.mem.eql for 99% of the possible attempts.

I've actually used this to implement the linear memory of a Wasm runtime (reserve 4GB and commit as needed) and have faced user complaints (it's in a library that uses a Wasm runtime internally) due to it unexpectedly running into

At this point, I've also basically abandoned my Google Play apps. I simply cannot afford the time to keep them up to date for no good purpose. And it's absurd. They were a perfectly sustainable “business” with a single unobtrusive

Then wait for Google to adopt it at large? If it (purportedly?) exists so that Google can move multi-million line code bases from C++ to something better bit-by-bit, because it's otherwise infeasible to do so, why would Google drop it

A functional adult doesn't need to ever go to a strip club. A functional adult in the 2020s needs to learn how to use Google and YouTube. It's actually part of the curriculum at school. The school also uses Gmail, and Classroo

OK, I didn't know that, though it's not very intuitive. Thanks! Now, as a parent, I face a tough choice: I have history on the kids accounts precisely because I want to check on it and discuss with them what's good, or less s

Good, at least they'll learn a useful skill in the process. Unlike what happens if they open the app and are pushed to doom scroll through dozens of videos on every 10 min school break.

As a parent (who also btw uses Google products every single effin day) I just can't agree. This is entirely Google's issue to fix. Yes, YouTube has amazing educational content. I'd really like to make it available for my kids

Thanks, didn't know this one! Have some reading to do. For a library that implements just the two component version of this, commonly known as a double-double, for a mantissa of 107 bits and an exponent of 11, see: https://g

Actually, the exponent is smaller. IEEE 754 64-bit binary floats have an 11 bit exponent, 1 sign bit, and 53 bit mantissa (one of the bits of the mantissa is implied, by actually knowing what they're doing, rather than… whatever this i

But that's also, IMO, why talking about it helps. I didn't start this thread to chastise anyone about it, but to express the idea that, in a country poorer than the US (on average), within 30 years, getting kids to swim early prob

I was struck by the comment that teaching kids young kids how to swim is uncommon in the US. I got my kids into swimming lessons on their first spring (was advised to avoid it during the winter). And it's part of primary education in m

Thanks for taking the time! I was the original contributor of the SIMD code, and got this… pushback. I still don't quite understand how you can marry ”pointer provenance” with the intent that converting between pointers and integers is

Hi Andy. Did you read the linked thread? I was not the one making this claim: > However, I believe that currently, there is no well-defined way to actually achieve this on the LLVM IR level. Using plain loads for this is UB (even if it

How is that a data race? Also, you're using unsafe. The post is about data races in safe Go leading to crashes or exploits, because things like "eface" (the tuple used to implement interfaces) and slices (again a tuple) are

Yeah, using LLVM for anything trying to avoid UB is crazy. I got involved in a discussion with a Rust guy when trying to get C with SIMD intrinsics into wasi-libc where something that the C standard explicitly state is “implementation defin
