Programming

[dayz () planet nl]

Hi,

I want to begin with learning programming to increase my knowledge about
security, but I don't know where to begin. Can someone tell me which
programming language is good to start with, and pherhaps what book
and/or online guides I should take a look at?
It would be nice that if I learn a programming language that it
shouldn't be much work to understand another one.

I am on Linux and Windows.

Thanks for the help.

Regards,

Ben
