It is a KornShell feature since ca. 1997 https://github.com/ksh93/ast-open-archive/blame/master/src/c...

Here are two checks using joins, one with sqlite, one with the join builtin of ksh93: check_empty_vhosts () { # Check which vhost adapter doesn't have any VTD mapped start_sqlite t…

Actually pdftex or luatex, but you are completely right, it can load a pdf file and do a lot of things with it.

Does someone have stock portfolio of superconductor manufacturer to share? I watch Furukawa, Sumitomo, and AMSC and they are performing not bad.

That article not even mention Bauhaus in Tel Aviv! https://bauhaus-center.com/bauhaus-in-tel-aviv/

Well, POWER9 and later CPUs have builtin hardware compression using the 8-4-2 algorithm. https://en.wikipedia.org/wiki/842_(compression_algorithm) https://github.com/plauth/lib842

for builtin security see for example https://unix.stackexchange.com/questions/102746/how-to-invok...

OK, for starter the while loop. Main rule of writing shell scripts is, Use The Shell, Luke. Don't start external programs, if your shell (which is already running) can do it. "whil…

This bash code is a parade example how NOT to write scripts.

I for myself get annoyed every time I see this misspell. The name is X Window. Even microserfs can learn it.

[edit] sorry, I've mistaken the concepts. The name is active memory deduplication, which sits on top on memory sharing. http://www.redbooks.ibm.com/redpapers/pdfs/redp4827.pdf [old…

This has nothing to do with Logo, the programming language. It's Python all the way down.

Yes, you are right. Bash 5 on AIX 7.2 works with process substitution. Thanks for the advise!

No, process substitution must be provided by the kernel/syslibs, it is not feature of bash. For example there is bash on AIX, but process substitution is not possible because the O…

No idea how old this command is. Most of the AIX/Linux admins I knew were very bad shell programmers, skills end with awfull for-loops, useless use of cat, and awk '{print $3}'.

FWIW AIX also has an apply command https://www.ibm.com/docs/en/aix/7.2?topic=apply-command

I'm disturbed by this awful loop, every time I see `setq' gives me the heretic though, that most of the eslip code is just Perl with parentheses. (cl-loop for sum = 0 then (+ sum (…
