This year's LinuxCon, which is celebrating its 20th anniversary, is happening in Vancouver from August 17th to 19th.
Getting 25 percent off the event's registration has been made very easy by the Linux Foundation: taking a simple, five-question quiz on Facebook nets you the discount (regardless of your score).
I took the quiz, called "Could You Do Linus Torvald's Job?" and got 4 out 5 answers correct, which dubbed me a "Linus in Waiting"—"You 'get' Linus and understand that with great power comes great responsibility. You could take the throne…someday."
