yeehaa!!! seems to be working ok!!! Also have a right-click menu that launches cmixer.
Brilliant idea of systemd to apply sysctl settings from configuration files ignoring their folders and the Debian Kernel team to put defaults in a "/usr/lib/sysctl.d/50-default.conf" file.
Why 50 and not 00? I have all my settings in a "/etc/sysctl.d/10-custom.conf" file. One of them was mysteriously erased by those defaults in a file starting with a higher name hidden in the system files.
Now I understand why all configuration files are prefixed by "zzz".
The Linux kernel has a feature where you can tune the behavior of memory allocations: the vm.overcommit_memory sysctl. When overcommit is enabled (sadly, this is the default), the kernel will typically return a mapping when brk(2) or mmap(2) is called to increase a programβs heap size, regardless of whether or not memory is available. Sounds good, right? Not really. While overcommit is convenient for application developers, it fundamentally changes the contract of memory allocation: a successful allocation no longer represents an atomic acquisition of a real resource.

Recently, I noticed that changed files were not picked up by the Nextcloud client as fast as before. As a result I sometimes missed a file (or changes in a file) on my laptop that had been created β¦

π₯οΈ My ultra-budget server powering http://websysctl.alfonsosiciliano.net has been running smoothly for the past 2 months. So far, so good!
π #Crawlers hit tens of thousands of sysctl parameter pages daily. That's fine, since robots.txt allows it. But why keep requesting non-existent pages as if the site were built with WordPress π€ ? Fortunately, the stack (#FreeBSD 
+ #OpenResty π + #Lapis βοΈ + a custom-built #database π¦ ) stays well within the limited resources of my $5/month cloud server.
The code might soon be #OpenSource stay tuned!

sysctlview https://www.freshports.org/deskutils/sysctlview/ is a GUI utility for sysctl on #FreeBSD.
It's probably my first #opensource project π¨βπ» , it's still in the Ports Collection π¦ and runs fine, but it hasn't been updated in years.
Maybe it's finally time to brush up on #C++ and give sysctlview a proper rewrite.
The original version uses #gtkmm (#GTK for C++), but a few years ago I ran a poll and most people preferred #qt
So maybe a QTsysctlview is on the horizon? π

SysctlTUI is Out!
The sysctl() system call can get or set the state of the system, the #FreeBSD kernel exposes the parameters for sysctl() as objects of a Management information Base (MIB).
sysctltui is a Text User Interface #sysctl #MIB explorer. It allow to view a parameterβs properties and get or set its value.

I don't have GitHub account, so replying here.
Not sure it's trivial enough or not, but wouldn't it nice if this deletions are done in 3 steps, like below in single commit per step?
Step1: Implement new SYSCTL macro to create alias of
any sysctl/tunable node (i.e., SYSCTL_ALIAS).
Step2: Use it for to-be-removed nodes.
Step3: Actually remove now-actually-alias old nodes.
This kind of renaming could happen in the future. So having clear way like
Step1: Add new node as usual and make existing
to-be-deleted ones alias of the new one.
Step2: In next or later *.0-Release, search and delete aliases
to avoid POLA violations within single stable branch.
This way, the 2nd step would become trivial (look for SYSCTL_ALIAS).
