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
Syslogd Overwhelming Your Computer?
If your Leopard (Mac OS X 10.5) system is unexpectedly sluggish, logging might be the culprit. Run Activity Monitor (Applications/Utilities/ folder), and click the CPU column twice to get it to show most to least activity. If syslogd is at the top of the list, there's a fix. Syslogd tracks informational messages produced by software and writes them to the asl.db, a file in your Unix /var/log/ directory. It's a known problem that syslogd can run amok. There's a fix: deleting the asl.db file.
Launch Terminal (from the same Utilities folder), and enter these commands exactly as written, entering your administrative password when prompted:
sudo launchctl stop com.apple.syslogd
sudo rm /var/log/asl.db
sudo launchctl start com.apple.syslogd
Your system should settle down to normal. For more information, follow the link.
