Hello every one, me new here.

I have setup a study list for myself and I'd like to know what you think about it in terms of "doable or no" and future of the subjects in my study list.

A small "about me", i'm working with a ISP as DNS, Security and Linux Engineer, I like web developing and i plan to start a small business. I have CCNA and A+ certs and good Cisco knowledge. And I'd like to be good at security related things.
Finally, I have N900 and like to work in Maemo, MeeGo developments.

I appreciate your input.
