Where do I learn things like hacking at?

-not necessarily hacking but things like that, I don't know what to call but all the nerdy ICT things?First you learn how computers work, right down to the component level. Learn the CPU and its architecture, learn memory and memory mapping.

Then learn to program in machine or assembler if you can't handle machine language.

Once you are proficient in computer architecture and programming then you can begin to learn how to hack.

Yes, it's a "nerd" thing and it takes a LOT of work to get there.

Learn the hardware and programming at your local college or university.

You are on your own for the hacking part.
Basic sites such as Youtube.com and Hak5.org and many others such as WonderHowTo.com provide a great deal of Information about Hacking and such. But a lot of it comes from self-taught knowledge, learn about how your and other computers work and then you will know how everything else that your computers depends on work.
