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.

If you haven’t been listening to iTunes Store previews recently, you might not have realized that they’ve largely been extended from 30 seconds to 90 seconds. And you’ll spend a lot more than 90 seconds reading Michael Mace’s fascinating explanation of why Apple is beating RIM, and how computing platforms die.

iTunes Store Offers 90-second Song Previews -- Lex Friedman writes at Macworld about how Apple has now modified the U.S. iTunes Store to play 90-second previews of songs longer than two-and-a-half minutes; that’s up from 30 seconds. According to Lex, not all songs have the new previews yet, and the longer previews are limited to the U.S. iTunes Store, presumably due to licensing restrictions in other countries. Still, 90 seconds is much better for getting a sense of a song. Oh, and look carefully at the screenshot; 90 seconds should be more than enough to get a sense of that piece!

It’s a few months old, but well worth reading for an insider’s view of how large technology companies can succeed or fail.
