The session schedule now has its own dedicated page as well as a link to the whole schedule in iCal format. The easiest way to keep track of sessions is to add it to your calendar app(s).
In case you didn’t know so far, anyone can get a hackerbeach.org WordPress account and add sessions themselves. Please ask on IRC if you don’t have an account yet, or if your account is lacking permissions to do so.
Go check out the page, and be sure to subscribe to the iCal calendar so you don’t miss the sessions you might be interested in.
