i hate file locks so much. but illumos and solaris are different OSes to rust (not to LLVM for boring reasons) and illumos does in fact have flock (github.com/rust-lang/ru...) so this is truly "only if you're running solaris"

Zag dit voorbij komen op instagram en ik denk echt dat we dit moeten doen met z'n allen. Eigenlijk gewoon het al bekendere "stop feeding the trolls", Hup. Met z'n allen.
In Brazil, federal deputy André Janones ran Lula's online mobilization with one rule: never engage with far-right posts. And now people in France started mass-blocking, not commenting, not interacting with any posts because every comment, even an angry one, pushes their posts to more people. So I tried to take the exercise further and thought, why not try to make it global? The far-right is really united globally so let's make sure the Left is too? Safir Boukhalfa Let's block the far-right 1. Don't comment, share or quote their posts. Not even to criticize them. 2. Want to react? Post a screenshot. Don't tag or link them. 3. When their posts show up, scroll past. 4. Block accounts that hurt you and your loved ones. Every block is one less person they can reach. 5. Like, share and watch to the end the videos or carousels of the voices you want to see grow, like mine. This goes for far-right parties, their politicians and influencers, and the media owned or funded by them and their allies. These steps work in every country. Safir Boukhalfa

Followup from last week's nextest vuln. Worth carefully paying attention -- please retweet!

When interpreting Cargo arguments across a trust boundary, ALWAYS join flags with their values, e.g. --package=foo, never --package foo.
repeated `-p` without a value lets the next arg be parsed as an option · Issue #17684 · rust-lang/cargo
Problem Cargo command line parsing has a bug that flags like --package accepts zero values. The intent was that so Cargo can provide a dynamic error listing all possible candidates. However, Cargo ...

Geen reden tot zorg. Gewoon te lang teveel gewerkt, te weinig rust en dus kost dat een paar dagen om van te herstellen. Zondag hardloopwedstrijd 10km. Daarna verwacht ik weer langzaam te kunnen beginnen.

Goose lang performs really good, count me surprised.
My first ten project Euler solutions in C, Rust, Goose, FORTH, and Factor graphed below. Sorry for having two y-axis scales.
Idfk what the deal is with the bloated Factor VM, I know way less of what I’m doing with that beast.
First ten Project Euler problems used as benchmark for C, Rust, Goose, FORTH, and Factor. C, Goose, and Rust are competitive, tying in multiple cases for both time performance and memory performance

Je hebt lang geprofiteerd van je dynamische contract en daar ook enthousiast over geschreven. Heb je dat nog, of inmiddels op 1 of 3 jaar? ik zit altijd op drie jaar als het maar een beetje kan en niet al te duur is, meestal heb ik geluk, ik hou van innerlijke  rust.

rustc nightly now has -Zasync-panic. We ran it on the Oct 29 nightly: with =no, a finished async fn returns Pending instead of panicking, and so does one whose body panicked. The tracking issue calls it a lang experiment. https://github.com/rust-lang/rust/issues/164106

Unless you have some new way to prevent this behavior from being confusing, it's unlikely that re-attempting it would succeed.
