> Teach yourself C in 24 hours.

been a week, and i still don't know it. LIES.

learn java first, then c, then c++. don;t ever touch python or it will set you back to the beginning (where i am now after a semester of forced python; relearning everything about data types).

i started with bash, then moved to c. there's no logical pattern in why i did it that way.

but yeah, i'm not a fan of python myself.
