https://www.intel.com/content/www/us/en/docs/intrinsics-guid... Intel's docs are unfortunately spartan, but the guarantees around program order is a hint that this is what it does.

I see, thanks. I had assumed incorrectly that NT writes operated the same as NT accesses, where there is no dedicated cache.

by m0th87 1y ago
There are no guarantees even if everything operates on the same core. Rust docs have some details: https://doc.rust-lang.org/stable/core/arch/x86_64/fn._mm_sfe...

I had interpreted GP to mean that you don’t slap on NTs for correctness reasons, rather you do it for performance reasons.

I work on optimizations like this at work, and yes this is largely correct. But do you have a source on this? > or (more likely) go into just some special small subsection of it reserved for non-temporal writes only. I hadn’t heard of th

That’s what I hope for, but everything that isn’t bananas expensive with unified memory has very low memory bandwidth. DGX (Digits), Framework Desktop, and non-Ultra Macs are all around 128 gb/s, and will produce single digits tokens p

This is almost perfect for my needs (communication and location sharing in areas without phone signal.) But it's missing GPS/GNSS. I'm not sure how niche that use case is, so more broadly I wish Lilygo offered something akin

I’ve heard Beaglebone Blacks are great (never used them), but have to say the experience with Blue was awful. I had a hardware defect that’s apparently commonplace. It gave me the feeling (maybe unjustified) that there’s a low bar for slapp

I’m definitely interested! Was just looking over this code and wishing it were in rust or C.

That's interesting, I didn't know they did that. But it could be better: 1) This alert doesn't show up at all on mobile. 2) IMO this should either affect the overall score or be displayed in search results as well, which is n

For what it’s worth, the person you’re replying to is one of the heavyweights of the rust community.

Just whipped up a (naive) solve in rust: https://gist.github.com/ysimonson/01a1dee41b1b5990c30568fd25... It usually solves this in under 6 guesses. The guessing could be improved; at the moment it's random, but it

R2 is marketed as "one less than S3!" I used the exact same tagline for a project open sourced in 2019: https://github.com/pachyderm/s2/ So there you go VCs, I can market as well as cloudflare. Money ple

I wrote up some rust low-level bindings for guile [1]. The problem is that Guile liberally uses setjmp/longjmp, which breaks rust destructors. It might be possible to fix this by wrapping every call the way rlua does [2], but I'm

You're not alone. I've been writing go since before 1.0, and can handle modules/packages in _any other language_ fine, yet go's regularly leaves me stumped. A little while ago we were hitting yet another issue with depen

It's not well known, because it's not true, at least not absolutely. Speed could either mean latency or throughput. Reference counting is almost always worse than GC at throughput, but is usually better for latency.

Yes, though this is arguably a big reason why SCTP didn't take off, which is similar to QUIC in a lot of ways (there is SCTP over UDP, but it was a second class citizen until WebRTC.)

Is it possible to context switch between userspace processes directly, without going through the kernel, i.e. a kind of fast, inter-process cooperative multitasking? I know earlier operating systems used inter-process cooperative multitaski

I maintain a couple of protobuf-based libraries, and the issue I've seen with its anemic type system is that it inevitably creates an impedance mismatch between itself and the host language's type system. To make the library usabl

4.5% self-report as LGBT. That's an important distinction to make, and I too would be surprised if it's accurate.

The point with weakrefs, though, is that they still require developer intervention. Also, you can use most memory management facilities in Rust (including reference counting) without `unsafe`.
