WWDC Tips

In addition to these, Quora also has huge list.

Registration

• Since WWDC started selling out every year, Apple instituted a lottery system for tickets. You enter when it's announced, and, if you're lucky enough to get one, you'll be immediately billed for the ticket. If you'll be needing your boss's permission (approval for the expense and/or the week off work), get it early.
• If you're a student, Apple usually offers a limited number of free passes through the Student Scholarship.

Travel

• If you can get a cancellable flight and hotel reservations at reasonable prices as soon as the WWDC dates are announced, book them. Otherwise, wait until you win the ticket lottery.
• If your passport is expiring within three months of departure, renew it now. You may have border trouble otherwise.

Here's my own list of the interesting stuff announced during this year's WWDC, collected from the keynotes, various Apple docs, blog posts and tweets.

If you're planning to watch the videos, I really recommend this Mac app that helps you download and watch them: https://github.com/insidegui/WWDC.
