46. "I think you may want to learn Linux, Python, and julia" In response to In response to 20
If you're trying to be a data scientist.
In fact I'd learn Linux and Bash first. Pick up The Bash Cookbook (O'Reilly) it will walk you through lots of exercises. The idea is to gain a facility for computers at a lower level - you will be amazed at how much you can get done with just one or two lines of code.
Julia (julialang.org) is a serious language for statistical / numerical computing. It's new but very well regarded. You might begin to work through the problems at eulerproject.net
