Passend zum #SysAdminApprecationDay veröffentlichte ich heute meinen Blog-Beitrag zur Rund-Erneuerung meiner #InformationsTechnologie: neues Smartphone, Umstellen von Kupfer- auf Glas-Faser-Netz, neues Betriebs-System WIN11. Und ein paar grundlegende Gedanken zum Thema IT für Freiberufler:innen.

Happy System Administrator Appreciation Day!

Systemadministratoren sorgen im Verborgenen für Stabilität, Schutz und Reaktionsfähigkeit.
Am heutigen #SysAdminDay erinnern wir daran. Unsere Forschungsprogramme können sie unterstützen. Die @Cyberagentur finanziert Werkzeuge, die Admins helfen, Systeme vorausschauend abzusichern. Forschung für eine sichere digitale Infrastruktur.

Linux tip: Use `systemctl --failed` to quickly identify which services failed to start after boot. Much faster than scrolling through journal logs when troubleshooting system issues. #Linux #SystemAdministration #SysAdmin
Linux tip: Set `HISTCONTROL=ignoredups:erasedups` in your init script to prevent duplicate commands cluttering your history. Clean history makes command recall much more efficient. #Linux #SystemAdministration #SysAdmin
I've been busy preparing my community course "Basic Linux System Administration" for a few weeks now. The next instructor-led cohort starts in September.
Here's the public chapter on text editing with vim. You can use it outside the course context, simply as a concise #vim tutorial.

Shell tip: `${var%suffix}` removes the shortest matching suffix. `${var%%suffix}` removes the longest. `${var#prefix}` and `${var##prefix}` work the same for prefixes. Mnemonic: # comes before % on the keyboard. #Linux #SystemAdministration #SysAdmin

Linux tip: `fuser -v /path/to/file` shows which processes have a file open. Use `-k` to kill those processes. Essential when "device busy" errors prevent unmounting filesystems. #Linux #SystemAdministration #SysAdmin
In early 2000 wanted to attend one of USENIX SAGE|LISA conferences. Never had an employer with the interest; a remotely related job; or enough money && interest to attend on own expense though.

SAGE - used to be "System Administrators Guild" via https://en.wikipedia.org/wiki/SAGE_(organization) ; could not find what it stood for in ~10 minute search.
LISA - "large installation system administration" via https://www.usenix.org/publications/loginonline/thirty-five-years-lisa ; https://www.theregister.com/2021/08/04/usenix_lisa_con_dead/

Version-control every configuration change. Use git even for single files. When something breaks, you can see exactly what changed and when. Your future self will be grateful. #Linux #SystemAdministration #SysAdmin #Coding
Linux tip: `ionice -c 3 command` runs a command with idle I/O priority. It only gets disk access when no other processes need it. Perfect for backups or maintenance tasks. #Linux #SystemAdministration #SysAdmin #Performance
Linux tip: `sysctl vm.drop_caches=3` clears page cache, dentries, and inodes from memory. Useful for testing cold cache performance, but never use in production scripts. Only for debugging! #Linux @#SystemAdministration #SysAdmin
Did you know FreeBSD includes a built-in utility for scheduling routine maintenance tasks?
From daily security checks to system cleanup jobs, the periodic system helps keep things running smoothly — and it’s easy to customize.
