Thank you for the answer.
Do you know any current iOS/Android application for data visualization, for example for simple line/scatter/bar plots where I can load .csv file and visualize data ?
P.S. You answer about analytic sources is very interesting :)
Great news! I played with matasano crypto challenges and Microcorruption. And as I understand this one is more greater and more enveloping. I was so excited when read "compiler theory" in the letter because I realized the LR(1) compiler engine in JavaScript, and these skills will help me in Starfigher I think.
