mum loves to tell that I could start games on our Atari 800 w/ XC12 before writing my name
learning Basic programming from the age of 6
first html and js programming with 11
started exploring windows network security about the same age
contact with Linux starting with SuSE 4.3 in 1996

custom kernels and Xfce in 1998 to match limited resources of old AMD K6 II 350MHz
going through SlackWare, RedHat, TurboLinux, Mandrake, Gentoo and Debian

early 00’s it’s all debian and servers, my home server lena which was the Eierlegende Wollmilchsau or jack of all trades
interest for all different kind of servers (Web, Mail, VPN, VoIP, etc) of course on encrypted filesystems
started learning C in 2003 when my first SATA controller drivers had lots of problems in Linux kernel
exploring network security in bigger networks to overcome http limitations in university network
