why do girls like creative emotional guys?

and how do i convince them that hacking kernals is just as creative as playing an instrument, if not more?

Music is inherently social.  As a musician, you're forced to be social and you're putting yourself out there. Social men typically do not have problems meeting women.  For fuck's sake, I was drunk one night and met this dude playing harmonica.  He had an extra one and we started playing together.  I have no idea how to play the harmonica, but groups of people and impressionable young women were stopping to listen to our drunk clusterfuck of a performance.  My brother is a professional street musician and he's got a girl he could never have gotten when he was just dicking around with a 4-track in between line cook shifts. 

As a general rule, computers are pussy-repellent.  While taking some courses at the local college, I saw hipster-nerd facades break down during an intro C prog course.  The only women who could even stand to listen to the lecture had dick-repellent tendencies.  Also, a lot of women mistake being good with computers with free tech support.  Maybe you can get a bj out of reinstalling windows 7, but you're probably just going to get used and tossed in the gutter like all those cumrags you have under your computer desk.

Getting women is all about marketing yourself.  You're no longer a kernel hacker, you're now a 'hacker'.  The difference is like reading 2600/Phrack out loud as opposed to watching Hackers.  You'll seem infinitely more interesting if you keep it vague.  Just boot into a Backtrack installation and run Wireshark or download Tor and show off the Silk Road.  Normalfags don't know shit about anything, so put your most attractive image of yourself in their minds.
