The situation is very confusing, but the tweet that went out with the announcement indicates it's not full 131k context yet and that is coming "soon"https://xcancel.com/CerebrasSystems/status/19437653011094202...

Note the announcement at the end, that they're moving away from the non-commercial only license used in some of their models in favour of Apache:

We’re renewing our commitment to using Apache 2.0 license for our general purpose models, as we progressively move away from MRL-licensed models

I think this is a really interesting area. I wrote a command line took for web reading with some similar motivations. In my case, you queue up the articles to read the next day.

If you're playing on the Steam Deck, mapping 'touch' on the left and right trackpads to the left and right bongo, and a touch on either joystick (they have capacitive touch) as a clap works rather well.

Oh that's interesting, I wonder what's different about your SVG favicon vs mine.

I used this trick for a quick favicon on my site https://muxup.com/ - though unfortunately Google/Bing/DuckDuckGo doesn't like svg favicons and so it's not displayed in search results. I should really add a proper favicon...

I think they should probably set LoopMicroOpBufferSize to a non-zero value even if its not microarchitecturally accurate. This value is used in LLVM to control whether partial and runtime loop unrolling are enabled (actually only for that). Although some targets override this default behaviour, AArch64 only overrides it to enable partial and runtime unrolling for in-order models. I've left a review comment https://github.com/llvm/llvm-project/pull/91022/files#r16026... and as I note there, the setting seems to have become very divorced from microarchitectural reality if you look at how and why different scheduling models set it in-tree (e.g. all the Neoverse cores, set it to 16 with a comment they just copied it from the A57).

I somehow hadn't come across this library, but have a whole blog post on the various ways people store data in pointers (and when+why it's safe) https://muxup.com/2023q4/storing-data-in-pointers

New comment by asb in "Is Emacs dying?"

Yes that's what I meant. Just an assumption I'd had, perhaps the joking about Emacs vs Vim preference in programmers made me assume the groups were of similar size.

One source of stats is the 2023 Annual Rust Survey. The question on text editors allowed multiple responses (so percentages naturally don't add up to 100%), but 5.5% of respondents reported using Emacs for Rust vs ~30% for Vim/Neovim, vs ~61% for VS Code. I was shocked that Emacs and Vim weren't closer. https://blog.rust-lang.org/2024/02/19/2023-Rust-Annual-Surve...

Obviously, it's possible this is a quirk of the Rust community. Though the Go survey shows similarly small Emacs usage numbers https://go.dev/blog/survey2023-h2-results (3% Emacs vs 16% Vim/Neovim).

(Article author here). I'm typically executing the same compile command from shell history (or via an alias) so missing off the `'; bell` isn't really a concern, but I agree that automatically triggering it after commands of a certain duration is a nicer way of avoiding that mental overhead if you're executing a wider variety of commands.

On https://muxup.com/ you should see pastel-coloured randomly drawn 'roguh' highlights for the site title and for the titles of individual articles. If you mouse over, they'll be redrawn while your mouse is hovering. If you're on mobile, you won't see that, and that's fine. It worked just fine on Android (FF or Chrome) and iPhone last time I checked, but do let me know if you're not seeing that.

It's really very simple, just thought the distillation of the 'rough' drawing technique to a couple of dozen lines of code for this use case might be of interest to some.

Yes, redrawing on hover was a desired effect - sorry if you find it offputting.

Also see RoughNotation <https://roughnotation.com/>, which uses RoughJS to support underlines, highlights etc.

I took some inspiration for my website (mouse over any highlighted title) <https://muxup.com/>. The write-up here aims to summarise how it works https://muxup.com/2022q3/muxup-implementation-notes#randomly... - if you click through you'll see it's really very little code.

Thanks for pointing that out - definitely a better choice for C++.

LLVM has a LoopIdiomRecognize pass which will, amongst other patterns, try to detect a loop implementing popcount [1] and convert it to the llvm.ctpop.* intrinsic [2]. I've not looked at why it's not matching this loop, but the sibling comment suggesting to just use `.count_ones` seems like the right answer for Rust. In C or C++ I'd strongly recommend using `__builtin_popcount` (provided by both Clang and GCC).
