Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Making a Wayland Compositor and WM using Rust
Maybe take a look at cosmic-comp it is currently in development by System76 for their own Cosmic DE. Smithay also has Anvil and Smallvil contained in it's repository, both are example implementations of a compositor using Smithay.

Is the new Cosmic DE going to improve stability, performance and especially BATTERY on pop OS?
COSMIC DE isn't a singular thing, it's a project of several smaller projects being built on top of each other, like the cosmic-text project that'll be used for font rendering and this new cosmic-comp UI compositor project.

Rust in industry
we have a lot of Rust projects of different scopes, but I am mostly working on cosmic-comp, a wayland compositor for our new upcoming Linux Desktop Environment. All Open-Source: https://github.com/pop-os/cosmic-comp

Will the Pop_OS Cosmic Desktop environment support Wayland?
Thanks for the reply /u/mmstick. Also, would you know what causes this issue: https://github.com/pop-os/cosmic-comp/issues/28 I keep running into it when trying to compile cosmic-epoch

COSMIC Panel First Look
We hired the talent behind smithay, and cosmic-comp is based on it, which has been developed to the point where we have an early prototype with some functioning wayland-shell applets.

Show HN: Usr/bin/env Docker run
The -S / --split-string option[1] of /usr/bin/env is a relatively recent addition to GNU Coreutils. It's available starting from GNU Coreutils 8.30[2], released on 2018-07-01.
Beware of portability: it relies on a non-standard behavior from some operating systems. It only works for OS's that treat all the text after the first space as argument(s) to the shebanged executable; rather than just treating the whole string as an executable path (that can happen to contain spaces).
Fortunately this non-standard behavior is more the norm than the exception: it works at least on modern GNU/Linux, BSDs, and macOS.

From Nand to Tetris: Building a Modern Computer from First Principles
> building a cat from scratch
> That would be an interesting project.
Here is the source code of the OpenBSD implementation of cat:
> https://github.com/openbsd/src/blob/master/bin/cat/cat.c
and here of the GNU coreutils implementation:
> https://github.com/coreutils/coreutils/blob/master/src/cat.c
Thus: I don't think building a cat from scratch or creating a tutorial about that topic is particularly hard (even though the HN audience would likely be interested in it). :-)

The Linux Scheduler: A Decade of Wasted Cores (2016) [pdf]
the yes command, writing to /dev/null, is making IO calls, which interfere with predictable scheduling.
If you look at the source code for yes, https://github.com/coreutils/coreutils/blob/master/src/yes.c
it builds a buffer of output and then writes that in a for loop
while (full_write (STDOUT_FILENO, buf, bufused) == bufused)

nohup not working?
Looking at the source of nohup, if the execvp() of the child happens then it _must_ have already done the signal (SIGHUP, SIG_IGN) so - WTF?

Is it fair to say "ls" is dead? No commits in 15 years
This got me wondering so I went and looked and it seems like lo and behold there was actually a commit to the GNU ls source just 2 weeks ago.

Decoded: GNU Coreutils
even an empty file? Yes. so now it was a file with a copyright disclaimer and nothing else. And the koan-like question comes to mind is "Can you copyright nothing?" well AT&T sure tried.
Then somebody said our programs should be well defined and not depend on a fluke of unix, which at this point was probable a good idea. so it became "exit 0"
Then somebody said we should write our system utilities in C instead of shell so it runs faster. openbsd still has a good example of how this would look.
http://cvsweb.openbsd.org/cgi-bin/cvsweb/~checkout~/src/usr....
At some point gnu bureaucracy got involved and said all programs must support the '-h' flag. so that got added, then they said all programs must support locale so that got added. now days gnu true is an astonishing 80 lines long.

Exa Is Deprecated
> Yes, ls is maintained. Although, maintained is a very strong word. It exists.
Why would it be a strong word? Here it is, in src/ls.c: https://github.com/coreutils/coreutils
It is then packaged by tens of operating system distributions, who themselves maintain extra patchsets, some of which are then upstreamed.
It is installed and used on millions (billions?) of devices, for 3 decades.
It's a very reliable and trusty "sharp stick of metal" :)
