+1. Expected a serious list, instead I saw stupid Ruby/JS/HTML garbage. And no, I do not need to know "100 Vim Commands" - because Visual Studio is "100" times better.

Here is the real list:

1) know one modern web tech; 2) know one OOP language; 3) know one functional language; 4) be familiar with one dynamic language; 5) remember where to look up theoretic bits like algorithms.
