comment Has “loginctl enable-linger user” made the UNIX classic “nohup” superfluous? Or have I misunderstood something?
execve only reverts the signal disposition of handled signals -- so what nohup does is signal(SIGHUP, SIG_IGN) before running the command, so commands that don't set up their own handlers (which is most text processing tools) will continue to ignore the signal even if it arrives.

comment 'Mice IS the scourge of the fields' <-- Plural noun - is/are - predicate noun
For company names, British English uses plural, American and Canadian English uses singular verb forms, that also trips up people sometimes.

comment Should order numbers be guessable?
You might be overthinking this, because the same problem affects invoice numbers, which in many jurisdictions have to follow a particular format anyway -- so if you solve this for order numbers, you don't gain much.

comment I am having problem installing VS Code on Ubuntu 24.04
apt -f install will fix it. If it can find a solution, then it will install the missing packages, otherwise it will remove code.

comment How can Firefox access /dev/dri/renderD128 when it should be only root accessible
yes, also it is possible to perform one-time operations on the file descriptor before handing it over, such as attaching the swapchain to a compositor.

comment How can Firefox access /dev/dri/renderD128 when it should be only root accessible
In addition to the ACL (which is the correct answer here) it is also possible for a privileged process to open the device, and pass the open file descriptor to another process, because permissions are checked only when opening.

Is your BBU okay? These are also checked periodically, and if they fail that disables all write caches.

comment How to find what is wearing out my SSDs
FWIW I've been running a build server for five years and it only made a 4% dent in the wear indicator, despite the SSDs being the bottleneck for most of the time.

comment Does Windows 10's portability limit OS features?
My suspicion is that this is about Spectre/Meltdown mitigations -- these make quite a difference in performance. "Less silicon" was the idea behind Itanium, that is not a commercially viable approach even if technically sound.
