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.

Three gaming-focused Linux operating systems beat Windows 11 in gaming benchmark
> I don't know what Popos does to make it more "gaming focused" than vanilla Ubuntu.
They have a few changes, chief among them being the PopOS scheduler which I find to be quite effective: https://github.com/pop-os/system76-scheduler
The desktop itself is a weird custom-baked x11/GNOME customization you won't really get on Ubuntu. Not many distributions can claim the title of being truly "unique", but PopOS does deserve the title in my opinion. Even still it wouldn't be my choice for gaming, but I'll defend it's identity as something more than another GNOME/Debian spin.

Ask HN: New ThinkPad battery life on Ubuntu
Power management kinda doesn't work on Linux. There are very minimal rules once you disconnect from AC, and most of the time you'll switch into high-usage mode when it isn't needed. There's not a clean way to fix this, to my knowledge; the Linux scheduler stack is just kinda based around desktop and server hardware.
That being said, I also use Linux on my Thinkpad anyways. There are decent enough workarounds that I can keep my system up for 5-6 hours when away from AC:
- Switching into battery-saver mode will keep clock speeds down, which generally reduces power usage (as long as you aren't slamming the cores)
- tlp can help if your hardware has power-draining characteristics (I don't use it, my defaults are good enough)
- Using an auto-nicer can keep your system feeling responsive when in power saving mode: https://github.com/pop-os/system76-scheduler
So... caveat emptor, YMMV. Linux is far from the most efficient OS away from the wall, but with a little bit of configuration I feel like my system does indeed work as a "normal laptop".
- What config format do you prefer?

System76-scheduler 2.0: getting horrible underrunning from seemingly within my interface itself
ran rtcqs as a replacement for realtimeconfigquickscan at the suggestion of Brock from System 76 (thank you Brock ily). As it kept suggesting that I build a custom kernel and I would rather switch back to Windows than do that, I checked github issues on system76-scheduler, found this: https://github.com/pop-os/system76-scheduler/issues/99. Seems to fit with everything I know about the situation.

For starters, you will get better performance using the stock (System76 kernel) but that's another conversation. To solve your specific issue you will need to install the missing dependencies with this command

How to avoid GNOME getting laggy when system is under heavy CPU use?
And installing and configuring system76-scheduler, it works by allocating the most resources to the window you have in focus, so say a full screen game or a browser you have open. Keep in mind that it only works with the POP-Shell extension and if you don't use it, you will need this one instead.

Fedora was added to the geekbench5 benchmark from the previous post due to popular demand. (On metal, Ryzen7 4700U,16GB Dual CH). All are fresh installations. Fedora did 15% lower in the Multi-Core HTML5 test dropping its total score. There is a 5% difference between the top and bottom Multi-Core.
If you start a game with game mode, then system76-scheduler lowers the game priority and makes your FPS lower: https://github.com/pop-os/system76-scheduler/issues/57

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" :)
