My mini review of #Manjaro as someone who doesn't like to micromanage computers:

+ It has installed on my NVMe + NVidia PC, unlike most other distros
- PackageManager UI is weird with it's "Apply transaction" thing, but works.
+ Nice that CLI auto-installs missing things
- NetworkManager eats 100% CPU all the time
- It goes to sleep even though I set all power-saving to off?
- I don't see an easy way (not "edit obscure config files") way to remap Caps Lock to Ctrl (must-have for ex-macOS user)

@rugk It is a reimplementation of Rust using GCC suite. It will enable use of Rust on platforms that LLVM doesn't support, easier bootstrapping, LLVM-free Linux build, and a second implementation to test against to avoid "bug-compatible" behaviors. It may also eventually have better perf/fewer bugs than LLVM.

Looks like #Rust in GCC is progressing nicely: https://thephilbert.io/2021/05/03/gcc-rust-monthly-report-5-april-2021/

If you know #C, consider helping out.

If you post "You can't eat a soup with a fork" in a #programming forum:

> Of course you can! Easy. Just freeze it. If you don't know basics of refrigeration, nobody can help you.

> JUST STOP ADDING WATER TO EVERYTHING. Sheesh! Forks work PERFECTLY with WATERLESS soups!

> Soups don't exist. It's an imaginary problem made-up by spoon fanboys.

@cadadr Yes, https://rust-lang.github.io/rfcs/2497-if-let-chains.html

A million compilations done so far.

`rg '#\[stable'` of rustc source code finds all feature flags names ever used, with Rust versions when they became stable, which helped identify exact MSRV with fewer compile failures.

I've also used -Z no-index-update option to reduce network usage (enabled on stable with the forbidden env var that shall not be named).

@amiloradovsky @veer66 This is running on Ryzen 5600X. With Noctua fan it's actually pretty quiet.
My smart meter has warned me about above-average use of electricity this week :)

@cadadr More than one let per if is forbidden in stable Rust. You've discovered an unfinished feature that is going to add support for if-let chaining, but as you see it's not ready yet.

@cadadr I can't comment on the Haskell part, but &str in structs is un-idiomatic, and in Rust should be avoided unless proven necessary, and even then probably use Cow instead.

@tjk As for override on the site, it'd be nice, but I don't have a mechanism for it. There's a spec for a Cargo.toml property to specify it, but it's not stable yet.

@tjk No, Rust deliberately avoids such situations. Changes are additive, and anything that isn't backwards-compatible requires explicit opt-in (via "editions").

@vincent It's chewing disk space so fast that I have `while true; rm -rf temp; sleep 60; done` running.

@grindhold later I also plan to measure how much code bloat and compile time each crate adds, and use clippy lints to spot amateur mistakes to rank crates in search.

@grindhold on https://lib.rs I want to show minimum required Rust version for each crate (e.g. https://lib.rs/crates/hashbrown/versions)

I'm trying to compile every version of every #Rust crate with every rustc version. Just a few million compilations to do.

I really strongly recommend investing in a microphone. You'll automatically sound more professional than everyone else with their tinny laptop mic.

Good lighting helps more than a better webcam. You don't need professional studio lights or overpriced ring lights. Just 2-3 well-placed lamps (watch tutorials!) will make a huge difference.

For #remote work having a good-quality microphone and camera is equivalent of dressing nicely to work.

If you wouldn't wear torn rags to the office, you shouldn't use a webcam that makes you look like you live under a bridge.
