This may or may not be a shamelessly self-interested question, since I will soon be in an connection-free environment until June for work. That said, I think it's an interesting thought exercise. What tools/materials would you download in advance? What projects would you work on to stay productive? Curious to see what ideas HNers come up with.

You can be connection-free and still geekier than those you leave behind for that time.<p><a href="https://othernet.is/products/dreamcatcher-v3-05" rel="nofollow">https://othernet.is/products/dreamcatcher-v3-05</a><p>Some history etc. of what OtherNet is:<p><a href="https://en.wikipedia.org/wiki/Othernet" rel="nofollow">https://en.wikipedia.org/wiki/Othernet</a>
1. A good game that can be played offline
2. A wikipedia database download
3. 100 books from Libgen that you know you'll want to read eventually.<p>Should all fit comfortably on a cheap USB drive, but maybe get two for redundancy.
