Ask HN: with little to no Internet for a year, how can I stay on top of my game?

I have been writing software both academically and for fun for over 5 years now. In a few weeks I will move to Argentina and live there for a year. I will be living with little to no internet access for this year. At most, I will be able to visit an internet cafe for a couple hours each week.

While the internet can be a huge distraction at times, it is also a major resource for software development. How can I stay on top of my game this coming year with such limited access? All suggestions and insights are welcome.

Note: I am not looking for some solution to gain access to internet, but rather ways to stay sharp and up-to-date without it.
