DB, What's That?

Today's the day! You finally made it to the conference you've been waiting for all year. You are so excited, you've scheduled the whole day with amazing sessions and you can't wait for it to begin. You look down at your schedule and see that your first session is, Need a clue? Digital Breakout EDU is for you! That sounds amazing; you find the room number and rush to get the best seat (the front row, of course), however, as you get closer to the room, you notice that there is a group of people standing outside of the room and the door is locked. There is a note pinned to the door, it says, "before you can enter, you must show your interest, you have 20 minutes to finish or else leave with a grimace." At the bottom of the note is a hyperlink; hurry to solve all 4 locks before the clock stops!
