In July 2000, David Haussler remembers crying as he watched the first fully assembled human genome streaming across his computer screen. He and Jim Kent, a graduate student at the time, built the first-ever web-based tool for exploring the three billion letters of the human genome. They had published the rough draft of the genome on the Internet a mere 11 days after finishing the herculean task of stitching it all together — a task assigned to them as part of the Human Genome Project (HGP), the international collaboration that had been working towards this goal for a decade. It would still be several months before the group published its analysis of the genome in the pages of Nature1, but the data were ready to share.
