BusyMac has released BusyCal 2.0.2, a minor update that puts paid to several bugs. The update fixes some unspecified Google Calendar syncing bugs, a bug that prevented past due to-do items from showing in the To Do List, bootstrapping bugs with Daylite and Zimbra CalDAV Servers, and a bug that occurred when entering start times between 0001-0059 in 24-hour time. It also adds an option to print multiple months/weeks when viewing a custom number of weeks/days. ($49.99 new, but currently selling for $29.99 solely via the Mac App Store, free update, 8.3 MB, release notes)
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.
