These visa categories have been specifically engineered to prevent you from working outside of your original job. Trust me, you do NOT want to screw with Immigration.
I'd been on J1/H1B/pre-Green-Card-waiting-list for a total of 10 years, so I had a lot of time to think about this.
Best shot if you are in an insane hurry: Marry a US citizen and really mean it. So better stop hacking in the evenings and go out. Start an interesting hobby. Get a hair cut. Read good books. Make friends that are NOT hackers. Get a tan. Eat good food. Smile at members of your preferred opposite gender and get super-comfortable talking to them.
Do NOT think about get-rich-quick-start-up ideas, it will only drive you mad if you can't actually start them up. Nobody wants to hang out with a person torn by the realization that they are in an impossible situation.
Enjoy the ride. You are young, bright and you work in an amazing field while living in a (presumably) fascinating place.
