Congratulations Armin, and Mario, and good luck.
Dug up the email, here's what my boss said directly:
In terms of tech to keep up on, it might be worth while to play around with node.js a bit as we've been doing a few small projects using the Express MVC framework. A great reference for js, (which I remember chatting with you briefly about) is Javascript the Good Parts (Douglas Crockford). You may also consider seeking enlightenment on Armin Ronacher's github page (he's a python master, leader of flask, genshi, pocoo, long time python contributor) https://github.com/mitsuhiko. His code is pretty top notch. I follow Kenneth Reitz quite a bit too (Armin and he often work on projects together). Kenneth is know for le*git and python's request library.
Interesting, considering I doubt I will ever see Pi in the context of computing and not immediately think of Raspberry Pi first.
I realize that legally speaking they can hold a distinct trademark for software when the other Pi is hardware but it just seems odd to me to lean so heavily on the trademarking of a commonly overloaded two letter name.
This is good too, I guess.
