It’s great that Apple has, for years now, made videos of most WWDC content available free of charge on the web. A problem arises though, when you realize that you want to quickly check the content of some specific session, only to realize you are either offline, on a slow internet connection, or just don’t have the time or patience to connect to Apple and download the video.
I’ve found it useful to use Olivier HO-A-CHUCK’s wwdc-downloader script, which he has recently updated for the 2015 URL conventions.
Essentially you just download the script to a disk with a ton of free space, run it, and you’re left with a permanent archive of all the videos and PDFs from a given year’s WWDC.
I’ll be waiting until I get home to run this script, since by then all of the videos should be available, and I’ll have easy access to that aforementioned big hard drive. It’s great though that he has updated it so promptly this year.
