Are you familiar with DOS batches?
If so, you can try starting writing some automation on DOS and then translating them into shell scripts. It was the way I started.
If not, you can try writing some basic automation scripts. Look for all of the repetitive tasks (copies, opening programs, clearing temps) and try to automate them. You will, unavoidably, start feeling comfortable and knowing all of the tools.
I worked for some time as self-employed.. The hardest part was to maintain discipline.

The most interesting part of the story is how they are celebrating and proud about having caught 'the leaders of Anonymous'. Can't they understand that it is decentralized and the arrested people could be leaders of a small organization inside the group, but not of the group itself?
About the immigration, I filed for a german citizenship. I don't know if it is going to be accepted, but with the documentation I've sent this is hard not to succeed.
And I will visit some places on my next vacations.. but I'm not sure about the reception I'm going to have. Any tips on where to go / how to contact the companies?
