Ask Slashdot: Programming Education Resources For a Year Offline?

An anonymous reader writes "I will be traveling to a remote Himalayan village for year and won't have access to the internet. What offline resources would you all recommend to help me continue to develop my coding skills? I think this would be a good time to get better at fundamentals, since I won't be able to learn any new frameworks or APIs. What about other, non-programming skills to practice and learn? Any ideas?" What would you bring?
