In 2010, Steven Levy, who wrote the 1984 book "", wrote that Zuckerberg "clearly thinks of himself as a hacker". Zuckerberg said that "it's OK to break things" "to make them better". Facebook instituted "hackathons" held every six to eight weeks where participants would have one night to conceive of and complete a project. The company provided music, food, and beer at the hackathons, and many Facebook staff members, including Zuckerberg, regularly attended. "The idea is that you can build something really good in a night", Zuckerberg told Levy. "And that's part of the personality of Facebook now ... It's definitely very core to my personality."
