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.

Good resources for learning C in depth?
AddressSanitizer is really useful, it's similar to Valgrind but has much lower overhead.
-
Memory Allocators
And if you're up for it, I'd further recommend adding some ways to deal with buffer overflows in debug builds. The way I deal with this is by using Address-Sanitizer's manual poisoning api. Bonus point if you leave additional poisoned space between allocations so off by one errors are likely to end up in a poisoned region instead of nearby allocation.

2023 Stack Overflow Survey: Rust is the most admired programming language, making it the most loved language for 8 years in a row
It also doesn't hurt that Miri can find many kinds of unsafe violations even in unsafe blocks. Zig may get something like this one day, but even if it does, checking things at runtime is not a substitute for compile time -- the C++ Sanitizers haven't exactly solved the safety story for C++ even over a decade later.

What's the best thing you've found in code? :
This is where stuff like ASan is really useful.

how do I check my library for memory leaks?
Use: https://github.com/google/sanitizers/wiki/AddressSanitizer
-
Is malloc_trim() safe to use?
Have you tried using tools like ASAN/LSAN or valgrind to confirm that there are indeed no memory leaks?

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.

Capture your users attention with style
So, this script serves as a pretty good wall replacement (wall will strip all escape/control sequences other than \007, by the way).

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.

Are DOS utilities open source.
Also a data format. Reasonably easy to find a spec (the wikipedia article should be sufficient to implement it). Also reasonably easy to find Free Software implementations, such as fdisk.
