Apple has updated iTunes U to version 2.0, with a bunch of new features for students and teachers. Students in private courses can now pose questions on the course, any post, or an assignment; and students in the same class can join the discussion to ask questions or provide answers. Teachers now have the option of creating or updating courses from their iPads and can use the iWork apps to create course materials. Students and teachers both can now receive push notifications for discussions. follow link
Smarter Parental Controls
If you've been using the parental controls options in Mac OS X to lock your child out of using a particular computer late at night, but would like to employ a more clever technique to limit Internet access, turn to MAC address filtering on an Apple base station.
To do this, launch AirPort Utility, select your base station, and click Manual Setup. In the Access Control view, choose Time Access to turn on MAC filtering. You'll need to enter the MAC address of the particular computer, which (in 10.5 Leopard and 10.6 Snow Leopard) you can find in the Network System Preferences pane: click AirPort in the adapter list, and click Advanced. The AirPort ID is the MAC address.
