A hackathon (also known as a hack day, hackfest or codefest) is an event in which computer programmers and others involved in software development, including graphic designers, interface designers and project managers, collaborate intensively on software projects. Occasionally, there is a hardware component as well. Hackathons typically last between a day and a week in length. Some hackathons are intended simply for educational or social purposes, although in many cases the goal is to create usable software. Hackathons tend to have a specific focus, which can include the programming language used, the operating system, an application, an API, the subject and the demographic group of the programmers. In other cases, there is no restriction on the type of software being created.

• Relevance
  How relevant is the hack to the category it was submitted under.
• Originality
  Is this just a reincarnation of an idea that has already been done, or is this unique? Is this a tutorial you followed on instructables, or is this your own work?
• Technical Difficulty
  This is relative to the submitter's skill level. How difficult was this hack to do given the time allocated? Was this just some polish on top of an already existing API or library, or did this require genuine hard work?
