Before 2006 I've worked mostly with hardware, but was developing some decent programs with Delphi, and special software for accounts department. So, my digital career started somewhere in 2000-2002.
Whole my career I was trying a lot of new things, read about MySQL, PostgreSQL, PHP (done some websites and simple scripts in it, as well as HTML/CSS), Python (a lot of authomatization).
In about 2008 I've started to use my own mail server (Postfix, Dovecot, Roundcube), and therefore I've started to use GNU/Linux for all those server needs. I've tried Linux for desktops a lot earlier, in about 2003, checked a lot of distributions, had Puppy Linux on a flash drive (128MB one), and always hoped that Linux will be the dominant desktop OS. But it failed, and I've lost my hope after 12 years. So, now I use Debian a lot for my servers, and Kubuntu for some work if I need something to be be done for Linux or in Linux.
