The Beginning
Raffael Willems, born in the eighties in Germany, Europe and based in Blieskastel.
My enthusiasm for computers began with an Atari ST and the Ommikron BASIC programming language.
Later I continued with an IBM Model 30 286/DOS6.2 with Quickbasic.
In the 2000s, I was on the Internet with a US Robotics USR3453B modem. Windows was my daily companion.
Around 2007 I started to get involved with Linux. Not as a desktop but as a server because I didn't really find it usable as a desktop (I had no idea), first Suse then Mandriva. a little later Fedora. Around 2011 I ended up with Debian.
From the beginning of 2013, I used Fedora with XFCE as my desktop environment because the recently released Windows 8 was simply terrible.
I don't remember exactly when I compiled my first DWM but Kai Hendry got me on the track of the Tiling Window Manager. Here are the Videos DWM Playlist
after this experience, I dared to try something bigger and my pacman.log 😀 says i installed my currently daily driver on 2016-10-06
