I'm Jack-Benny, the owner of [CyberInfo Sverige](https://www.cyberinfo.se/) and 
[CyberInfo Consulting Sweden AB](https://www.cyberinfo.se/konsult/). 

But who am I, really? I don't know actually, but isn't that the fun part?
Not knowing, just exploring, loving, being.

I like to tinker with computers, and Unix related things in particular. I also
like old computers, pagers, networks, and phones. I also like to write about these 
adventures. I attend demoparties whenever the opportunity presents itself (but
to this day, I haven't written any demos). I take notes with pen and paper,
and keep an old-school diary.
