Viewing Wi-Fi Details in Snow Leopard
In Snow Leopard, hold down the Option key before clicking the AirPort menu. Doing so reveals additional technical details including which standards, speeds, and frequencies you're using to connect, as well as what's in use by other networks. With the Option key held down and with a network already joined, the AirPort menu reveals seven pieces of information: the PHY Mode, the MAC (Media Access Control) address, the channel and band in use, the security method that's in use, the RSSI (Received Signal Strength Indication) measurement, the transmit rate, and the MCS Index. In Leopard, some, but not all, of these details are revealed by Option-clicking the AirPort menu.

iTunes U Downloads Exceed 300 Million
Apple has announced that iTunes U content downloads have rolled past the 300 million mark. iTunes U doesn't get much press, but the division of the iTunes Store brings together audio and video educational content from hundreds of universities; it now contains over 350,000 lectures and other content from institutions of higher learning around the globe. Apple deserves kudos for providing iTunes U content for free, and if you haven't yet checked out the iTunes U section of the iTunes Store, we encourage you to do so. follow link
