My first contact with GNU/Linux was about 17 years ago with Slackware at the college ( where I also worked at computer labs ). At that time there was a company in the city that used to work only with GNU/Linux and Open Source Software ( lucky me ). Because of that I had the flexibility to change between GNU/Linux distros and some UNIXes without major problems.

Alas, the most recent companies that I've worked with used a bunch of proprietary tools that made my NIX* life quite difficult ... :(

- 2006-2008 : Slackware Linux ;
- 2008 ( about 9 months ) : FreeBSD ;
- 2008-2019 : Gentoo Linux ;
- 2019-2021 : OpenBSD ( as personal PoC );
- 2021-2022 : FreeBSD ( as personal PoC using bhyve );

Nowadays I use FreeBSD in my personal X220 and OpenBSD at work.
