If you’re a GitHub user, but you don’t pay, this is a good week. Historically, GitHub  always offered free accounts but the caveat was that your code had to be public. To get private repositories, you had to pay. Starting tomorrow, that limitation is gone. Free GitHub users now get unlimited private projects with up to three collaborators.
