Hundreds of college students will be in Ann Arbor this weekend for a 36-hour hackathon competition.
MHacks will run from Friday night to Sunday morning at Michigan Stadium.
At stake is $25,000 in prizes. Hearst Automotive, Google, Facebook, Amazon and Twitter are sponsoring the student-run event.
The definition of "hacking" for some refers to gaining unauthorized access to files or systems. Those taking part in MHacks are tasked with making, not taking.
Competitors will be creating websites, mobile applications and the like.
The hacking won't take place on the football stadium's playing surface. It'll be done in the luxury seating area overlooking it, although the field will be open to other activities.
MHacks organizers are providing buses free of charge from locations across the U.S.
