Hi! I’m Dennis Klein, geek, blogger & otaku!
My wife, me and our cat are living in a white house in a new housing estate. It’s great to have mostly the same hobbies. We share the the fascination for photography, loving to ride rollercoasters and having fun watching Animés, reading Mangas and collecting figures.
I’ve always tried to look for alternatives for the currently used OS on my computers. I use a lot of Linux (mainly for servers) and have experiences with FreeBSD and Solaris as well. My personal favorite desktop is still a Mac. Tried to switch back to Windows for a couple of weeks, but honestly, even if I’m not a fan of the most new features in Lion, I like it much more than Windows. At the moment, I’m preparing for the first MCITP exam.
When it comes to music, I rarely listen to it lately – working in a quiet room is mostly what I do to concentrate on what I’m doing. I prefer Rock music (my favourite band was a long time Bon Jovi).
Since I left Medion back in 2006, I was doing Web Design & Web Development – on my own and for Cisco. Looks like I missed a lot of stuff like all the shiny frameworks that you have to know (as it seems). I’m coding in a very puristic (some may say “old school”) php, but for me, that worked.
Please take a look at my job search site (in German).
