To all #Rust programmers on #Linux that want to use the kernel's new pidfd feature to asynchronously await on many child processes from the same thread -- reliably -- I've released the [pidfd] crate, which achieves precisely that.
Note, however, that Linux 5.3 is the minimum requirement to use this crate. Linux 5.4 is required to get the exit status from terminated processes (use the `waitid` feature).
Testing would be highly welcome!
This doesn't build yet, but it will be the first commit to replace gnome-shell's style code with Rust. Here, replace color parsing with rust-cssparser. Adds hsl() and spec-compliant parsing as a bonus.

Recorded at System76 Headquarters from the 3rd annual Superfan event, this one is special.
Hear from CEO Carl Richell about the company's laptop plans, their roadmap, the features coming to Pop OS, the origins of System76, and so much more!
With the new async / await syntax in #Rust, working with futures is easier than ever.
This weekend, I've spent some time rewriting my `async-fetcher` crate with the new syntax. The result is more features, and better performance, at a fraction of the original amount of code.
The new rewrite now supports execution on current-thread runtimes, with optional support for speeding up downloads by using multiple connections to download the same file from multiple URLs.
It is proven! I am mmstick on Keybase: https://keybase.io/mmstick/sigchain#a7ba9db324102582d38d7d54cb0e7f645fccd3d66ee501691b6525ca1cff2dd40f
To all that are using , the GNOME Shell / Mutter optimization patches were pushed to the stable repositories last night.
After upgrading to the latest packages, you will need to reboot in order to see the improved performance.
A recap of all of the included patches will be in this week's, "This Week in Pop!"
* Intermittent desktop hangs that last for a few seconds, where the mouse stops responding
* Massive screen tearing of windows on external displays
* Visibly-noticeable laggy mouse movements
* No more desktop hangs
* Smooth mouse cursor movements
* Tear-free external displays
* Noticeably more responsive applications
There's a "geometric picking" patch, for example, which cuts NVIDIA CPU usage in half.
I'll announce whichever patches I test that end up working out. With any luck you'll have a more responsive Pop!_OS desktop by the end of the day.
#system76 is now hiring for both a senior back end web developer, and full stack web developer / team manager. Experience with #elixir and the Phoenix web framework is required. Must be willing to relocate. See the career page for more details. #linux developers, represent!
