Is this the way forward for the EU? Genuinely curious: Are there any EU providers that host the very good recent Chinese open weight models? Like, an EU-based alternative to DeepSeek's own API offering? To me, that sounds like an easie

Because this code block looks quite complex, I want to add that it can also be just smol::block_on(async { println!("I'm async!"); }); (I thought tokio had a helper like this too but could only find `toki

Ripgrep includes one of the most prominent algorithms from Hyperscan internally for some expressions. Longer story: Ripgrep uses Rust's regex library, which uses the Aho-Corasick library. That does not just provide the algorithm it is

Technically, he only got tested the day after Christmas, so I'm assuming they picked the more dramatic date.

There's no need to take that bet if you can instead just read the article, however. No idea why you bring up a German statistic.

This is as suprising as the amount of comments assuming the nurse is female. Edit for those who just comment after reading the headline: The article clearly states the nurse is Matthew W. and uses the he pronoun in the following sentences.

Start at part 1. No, he doesn't give you an answer, but you might just find it interesting enough to no longer have the qusstion.

Author here. Please note that the "cheap" in the title refers to the effort needed as well as how sophisticated the tricks are; benchmarking and optimizing your algorithms is still super important! This was discussed quite a bit o

Tar was released in '79 iirc, so it's about the same age.

Hi, author of large parts of this here! This was written in the lead up to the Rust 2018 edition release last year, but it should still be pretty much up-to-date. There is a lot of more info and discussions on the associated repo [1]. We di

Not sure. Having the ability to abstract over tuples (using a similar mechanism as HLists for example) would help.

I can't speak for the actix-web maintainers but I did find this in their examples: #[get("/resource1/{name}/index.html")] fn index(req: HttpRequest, name: web::Path<String>) -> String {

Correct. Fun fact: The amount of traits implementations that need to be generated to support tables with 128 columns actually makes diesel an interest benchmark of the Rust compiler.

The simple builder pattern often looks like a lot of boilerplate, I agree. But you can easily crank the coolness of it up a notch by using one of these properties: - Hide the fields of your struct to not break your users when adding/ch

Took me a while to find it, but Rust's iterators have an `.inspect` method that gives you a read-only reference, so println debugging works fine. For more advanced tap-like stuff, use the `tap` crate (which allows you to write `array.t

This also makes incremental compilation faster, doesn't it?

Please note that upx also compresses your binary contents and decompresses it at runtime. When downloading a WASM file over HTTP, the server can gzip it transparently. It'd be interesting to compare the effects on the size with what up
