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.

Don't abuse su for dropping user privileges (2015)
I assume that is why I see gosu [1] used so often for dropping privileges. It's good to have some explanation as to why su is unsuitable for this.

What is the best approach to log your NodeJs application deployed on K8s?
Use a tool like https://github.com/tianon/gosu to set up signals properly and drop privileges, then just print everything to stdout and it will hit your logs fine. As for the logs themselves, I just view them in my dashboard, which takes essentially no resources. Every other solution I have found takes an insane amount of resources to run (looking at you Elasticsearch).

Simula the Forgotten Programming Language
>It remained in the "getty" process for some time, well into the {Free,Net,Open}BSD era.
Still there in agetty: https://github.com/util-linux/util-linux/blob/master/term-ut... And, I imagine in other getty implementations.

Don't abuse su for dropping user privileges (2015)
TIOCSTI is irrelevant. When one is dropping privileges, in a system cron job or in a process supervised by one's favourite service management system, there is no terminal involved. TIOCSTI simply doesn't enter into the picture at all.
Only when one is in a terminal login session and using su to elevate / add privileges, does TIOCSTI become relevant. But no-one here is saying not to use su to add privileges.
People blame su, sudo, and (as the person at https://github.com/slicer69/doas/issues/110 did) doas for this feature of operating system kernels. The right thing to do with TIOCSTI it to just eliminate it from the kernel. OpenBSD did back in version 6.
Sadly, the argument from Alan Cox, Linux developer, when this was proposed years ago was that it should stay in Linux, and all of the programs like su, sudo, and doas should have even more things to do in the parent process that sticks around, namely pump I/O to and from a controlling pseudo-terminal that su/sudo/doas sets up for the shell subprocess, breaking (as the maintainer of OpenDoas pointed out) the long-standing notion that the child processes belong to the same terminal session and share things like a single getlogname() with the login shell.
6 years after https://www.openwall.com/lists/kernel-hardening/2017/05/10/3... and https://www.openwall.com/lists/oss-security/2017/06/03/9, there is no sign of anyone doing anything of the sort in any su or doas implementation. (It was briefly in one su implementation, but taken out in 2017 for being a "stupid hack": https://github.com/util-linux/util-linux/commit/23f75093264a...)
Fortunately, some six months ago Linux developers finally made TIOCSTI removable and the right course of action is available to those that want it: https://lore.kernel.org/lkml/20221228205726.rfevry7ud6gmttg5...

Desktop Suddenly Failing to Boot - what are these error messages?
Huh, I will try this later. Bit confused by the instructions on the Archwiki but I think I can figure it out. Thanks so much for the help. Btw, it seems you were right on what was wrong. Good eyes.

Would you use/try snaps if it has open source backend?
if anbody actually at Canonical is reading this and wants me (and others) to take snaps seriously, please consider submitting pull requests to some of the core cli tool projects impacted by the way you guys abuse the loop device mechanism. Something simple like the ability to export HIDE_SNAP_MOUNTS=1 that gets picked up by the impacted tools in util-linux (lsblk, mount, blkid, fdisk, etc) and gnu coreutils (du, df) and simply hides the lines related to loop device mounts would go a long way - preferably only the ones added by snap but even an option to hide all of them would be better than nothing.
