St. Clair Software has updated their CPU-saving utility App Tamer 1.3 with more control over when the AutoStop feature gets activated. With this update, you can set AutoStop to begin working its magic only when your laptop battery falls below a specified charge level, which will help minimize battery drain and speed up recharging. The release also includes several AppleScript commands that enable you to turn AutoStop on and off as well as wake a stopped application in your scripts. Additionally, this version fixes a problem that caused Web browser helper applications to freeze the browser and an issue where disabling AutoStop didn’t actually disable the feature for some machines.

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.
