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

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
