What Type of Coding Is Most Important for Hacking?

Hey guys,

I just started OTW's Basics Of Linux course (I figured that one is pretty essential). But what type of coding do you see yourself using the most? I was going to head over to code academy after I finish OTW's course.

"Codecademy is an online interactive platform that offers free coding classes in 9 different programming languages including Python, PHP, jQuery, JavaScript, AngularJS, and Ruby, as well as markup languages HTML and CSS." They also opened up SQL and Java classes.

My goals are too be able to understand how to send payloads and R.A.Ts, AND be able to use them. Also toorecognize and understand how to capture hashes

Thanks

Oh ps how the hell do I get rid of my real name on here and change it too a nick name. Ahah.
