Hacking is core to how we build at Facebook. Whether we are building a prototype for a major product like Timeline at a Hackathon, creating a smarter search algorithm, or tearing down walls at our new headquarters, we are always hacking to find better ways to solve problems.



Today we are announcing open registration for Facebook second annual Hacker Cup. Programmers from around the world will be judged on accuracy and speed as they race to solve algorithmic problems to advance through up to five rounds of programming challenges. This is your chance to compete against the world best programmers for awesome prizes and the title of World Champion.
