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

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

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.
