Why do Linux users never get locked out of their house?
Because they always have a terminal open!

😈 New: the FreeBSD CornerThe BSD side of the house: what is different from Linux, upgrades, ZFS and more. Same tone, red hat.
About This Site
TechCommune is the lovechild of 25 years of staring at screens, debugging configs, and pretending rm -rf / was a joke until it wasn't.
⚠️ Warning: This site contains actual knowledge, but also a lot of opinions and questionable shortcuts I've learned the hard way.
What You'll Find Here
- A FreeBSD Corner for the BSD side of the house (what differs from Linux, tested on FreeBSD 15)
- Linux command line tips (with warnings about the ones that can delete your files)
- Cloud platform tutorials (AWS, Azure, GCP — pick your poison)
- AI best practices (local and free setups)
- Shell scripting guides (because everyone writes them differently)
- System administration techniques (from both successes and disasters)
- DevOps and container cheat sheets (Docker and friends)
- Linux security advisories (what is vulnerable, what to switch off, and which kernels are patched)
- Linux hardening (the basics, containers and Kubernetes, plus CIS, PCI DSS, HIPAA, STIG and friends: locking the doors before someone tests the handles)
- A contact form for questions, corrections and kind words (plain text, 500 characters, and it goes to a real human)
- Handy tools (a subnet calculator, cron generator, chmod calculator, timestamp converter, Base64 encoder, port reference, printable chmod/umask/CIDR cheat sheets and a what's-my-IP checker, all running in your browser)
- A community wiki for fixes, tips and war stories from readers (proposed on GitHub, read by me before anything is published)
Why did the Linux admin keep a Windows VM around?
To remind themselves that troubleshooting can always get worse.

Found a fix that took you an hour and saved you ten? The TechCommune Wiki is a shared notebook for exactly that. Here is how to add a page: you need a free GitHub account and a web browser, and there is no form to fill in.
The Three Rules of Engineering
- If it works, don't touch it
- If it breaks, sudo it
- If you can't figure out why it broke, add a sleep and pray
