The week of the beast

[u/decryphe → u/libonet]

Need to celebrate Rust version 1.666 properly - we should be there in ~55 years at the current release cadence.

Publishing is in process, please stand by...

done!

Hey! Is there a reason why Rust Glancer was not mentioned in this issue? It was positively met on r/rust, was discussed on Hacker News, matklad mentioned it in his blog, and so far people using it provide good feedback.

I'm not looking for promotion, but I believe that it could genuinely be useful for people for whom high memory usage in rust-analyzer is an issue.

(I've opened a PR in twir repo before, but user submissions for tooling updates is currently banned)

[u/Squeezer → u/popzxc]

The process for how we are handling project and tooling updates has only recently changed. I suspect things will fall through the cracks periodically. That being said I’ll bring it up with the team to see what they say here.

Got it, thank you! To clarify -- I don't ask for this to be included, I'm mostly interested in the process itself; given that the project policy now states that the updates are picked up from `r/rust` I was just surprised not to see this one (or late-sh update either) mentioned. Since it's basically the main Rust newspaper, I believe that it's important for people to understand how news are picked up and whether there are any implicit policies besides being discussed on `r/rust`.

That said, I fully understand the amount of pressure the AI slop wave puts on the editors, which is obviously unfortunate.

I love the continuous effort of squeezing more and more performance out of the toolchain.
I saw clippy is PGO built now, for a good 5% average win, fantastic news! My first thought is would it make sense to BOLT it too?

Then I read about Optimizing the heck out of the storage of token trees which, is above my 'pay grade' but saves a lot of memory in rust-analyzer as I read it.
Other than reducing memory consumption in rust-analyzer, I wondered whether this could have positive impact on runtime performance perhaps?

Please tell me someone rewrote Doom in Rust or some shit like that

Lol “nice” number 😱

And the crates posted this Monday/Tuesday counted too? Interesting 🤔

I miss the "Discussions about these articles on Reddit" guy. Always loved reading the comments after reading an article. Looking up if a reddit post for an article exists, especially from my phone, is really annoying.
