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

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. "while /usr/bin/true" is nonsense,

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

Well, Kornshell (ksh93) has some nice programming features, much better than bash.

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] It is called active memory

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!
21.
by pgtan 5y ago
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 OS do not support it.

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 (* total 0.1)) for total = 100 then (*

Thanks for sharing! Those must be exciting times. I remember tweaking the fonts only once for printing my diploma thesis back in the 90s; but contrary to the most opinions, I made the fonts even lighter, because of the ultra white paper, we

If you have a certain printer to use, you can tweak the Metafont mode for the fonts and create your preferred look. The definitions for various printers are in the file modes.mf For example: % From {\tt stsmith@ll.mit.edu}, 10 May 93. % Wit

It is you. CM is based on the Modern fonts used in scientific typesetting decades before Knuth made a MF version of it. I had often chance to give non-TeX (coming from humanities) proofreaders and copy-editors the choice between Times and C
