I know what I know, but I'm no professional.
The first computer I had access to was an Atari ST, my step brother and I shared. Years later I found a second hand 14.4kbps modem but had no idea what to do with it. I started learning html from a book I bought at WHSmiths, typing out the examples on my old mac (back when a mac was a sideways tower with a separate monitor) and opening them up in netscape (I still wasn't connected to the internet).
In the years following I bought a Redhat linux for dummies book, I was about 14 at that point. I read it cover to cover but had no way of installing it from the CDSs provided (This somewhere between MacOS 6 and 7, maybe. Before OSX).
By 16 though, I had my first personal computer, a 56.6kbps modem and Linux Mandrake at my fingertips. I discovered nmap and netcat and tux racer!
I was never at school so when applying for computer science I was turned away under the assumption that the mathematical aspect would be too complex for me to grasp.
Maybe it's better, computing is a hobby for me. I learn what I chose to, and help where I can. There is so much I have never begun to learn that it would be foolish of me to act elite-est towards others.
I know what I know but I'm no professional.
