Great article. It really drives home what a damn shame Intel's persistent mishandling of AVX512 has been ever since its introduction. I don't even know if it has a future outside of extremely niche libraries given how scattered ha

Every time the question of preferred programming languages comes up, I'm usually in the extreme minority with my preferences being Rust (for small/fast) and C# (for productive and easy, where GC is acceptable), a combination that

There are many reasons, though I am not sure which they had in mind. One thing is that LLMs in general tend to do better when they can be more verbose in their output and sort of “think aloud” to reach an answer. Insisting on strict outpu

Sure, I don’t disagree with the basic premise. I actually wasn’t passing judgement (despite my wording!), rather I was merely trying to say that despite such a massive unexpected windfall, their finances are still in the gutter.

It's not much of an article, but the question is certainly on everyone's mind. The crazy part is that this is all after how much Intel has benefitted from the CHIPS act (financially, not strategically, as it's too soon for

Shameless plug: we maintain a cross-platform/cross-language secrets store (with cli tooling available) to portably read and wrire secrets (but it doesn’t use the OS facilities for encryption). Linking to the rust implementation because

SQLite doesn’t require a file system per se, as you can create an in-memory db and then use vfs to load/write the actual data from/to your IO layer.

The chosen solution isn’t ideal for all cases, especially those with many or large records. It doesn’t require parsing all the bytes of a payload but it does require reading them (because it’s a sequential scan of all content). A better s

I’ve been using the ffmpeg wasm library directly for a couple of years now and it’s working OK in production though it has a number of critical issues that don’t show up except in heavy testing with a wide variety of inputs and outputs. Not

They caused a huge commotion some years back when they removed the entire concept of variants from ports/formulas, removing the ability to set any build time options whatsoever, breaking all patches for older platforms, etc. maintainer

Normal async doesn’t require any malloc.

Then you no longer have 14 cores in this example, but only len(P) cores. Also most code written in the wild isn’t going to use an architecture-specific library for this.

It’s a common strategy for small tasks where the overhead of dispatching the task greatly exceeds the computation of it. It’s also a better way to maximize L1/L2 cache hit rates by improving memory locality. Eg you have 100M rows and y

Ffi: you have a c api that exposes an item by ptr not by ref so it mustn't be moved. Interacting with system types that rely on their address. Eg I think std uses a pin equivalent for mutex/futex on some operating systems because

All this is fine and dandy for async web apps but would make things like async-as-state-machine, which powers a lot of rust embedded development, basically a non-starter.

Is there a screencast (preferably with a transcript of pressed keys) that we can see? Because I’m not entirely clear on what this is, exactly. Is it like a tmux that automatically creates/arranges new panes for new processes?

The problem is that once you say “fine tuned” then you have immediately slashed the user base down to virtually nothing. You need to fine-tune per-task and usually per-user (or org). There is no good way to scale that. Apple can fine-tune a

I’m late to the party but this mostly rehashes already voiced concerns with all the existing “updated” strcpy functions. But what I was surprised to learn is that strdup wasn’t part of the C language spec (until now)!

That’s kind of my point. They’re clearly running a buggy codebase to begin with that I wouldn’t trust a crash to mean hardware failure.

This seems like deflection to me. There’s no reproducer, no technical info, no objective facts besides what is basically a meta study that lumps their code quality with intel’s hardware correctness as one metric. If it’s as they say, switch
