Apple has announced that downloads of iTunes U content have topped one billion. iTunes U doesn’t get much mainstream press, but it could be one of Apple’s most important projects, hosting over 2,500 courses (and thousands more private courses) from over 1,200 colleges and universities, plus another 1,200 K-12 schools and districts. Some iTunes U courses have as many as 250,000 students enrolled in them, and over 60 percent of the iTunes U app downloads originate from outside the United States. Put simply, iTunes U is an astonishing educational resource. follow link
Springy Dock Tricks
If you drag a file and hover over Dock icons, various useful things happen which are similar to Finder springing. If it's a window, the window un-minimizes from the Dock. If it's a stack, the corresponding folder in the Finder opens. If it's the Finder, it brings the Finder to the foreground and opens a window if one doesn't exist already. But the coolest (and most hidden) springing trick is if you hover over an application and press the Space bar, the application comes to the foreground. This is great for things like grabbing a file from somewhere to drop into a Mail composition window that's otherwise hidden. Grab the file you want, hover over the Mail icon, press the Space bar, and Mail comes to the front for you to drop the file into the compose window. Be sure that Spring-Loaded Folders and Windows is enabled in the Finder Preferences window.
