I thought the vscode ssh extension's automatic port forwarding feature was neat and assumed it was doing something smart like watching procfs but no it's looking for localhost URIs in stdout

We should have a leaderboard issue on the r-a issue tracker for people to post their observed peak memory usages of rust-analyzer. So far the highest a friend reported to me was 80gb I think

your rust app really reaches a milestone when you catch it using 40GB RAM with no explanation whatsoever

Just released quick-junit 0.5.2, containing (from what I can tell) the first industrial-strength (i.e. with fuzzing and roundtrip property-based testing) JUnit XML parser for Rust!

quick-junit's serializer is used by cargo-nextest.

Check it out:

Scipy is a phenomenal library. It's not every day that one can beat its performance by 1-2 orders of magnitude. Today is that day, though!

Must-read post if you care about any of:
- high performance Rust
- numerical methods
- how Rust can make Python faster

Take a look under the hood of the state of the art in grid interpolation in Rust and Python!

Come for the compile-time loop unrolling, stay for the profile-guided optimization!

What's the list of clippy lints you deny in production? I'm thinking await_while_holding_lock, stuff like that?

Part of the reason why I’m so insistent about folks understanding AI capabilities is that they’re here to stay and we need to start thinking about what to do in such a world. Putting the genie back in the bottle is a pleasant fantasy that delays serious reckoning

Claude is ex-Adobe confirmed:
Claude has cast an immutable reference into a const pointer, into a mut pointer to assign something.

Can we get an EU regulation to outlaw phone speakers? Or any speakers for that matter? I think I've been spending too much time in trains lately

Anyone here had a good experience with dioxus’ subsecond? (ie. it worked?)

And about their wasm-split feature? Neither works for me right now.

Is there any way to get cargo-hakari to work with dioxus projects? Those build with the 'server' feature flag (for x86_64 linux) and with the 'web' feature flag (for wasm32-unknown-unknown) so.... hard to unify.

Luca Palmieri @lpalmieri.com & Amos Wenger @fasterthanli.me challenged us with the trickiest corners of Rust — fun, fast, and delightfully unfair.
