Jamawkinaw Enterprises has released version 1.0.10 of its Downcast podcatcher app with new options for sorting local episodes by time remaining and file size. It also adds a 1.25x playback speed option and an episode count to the Local and Available episode lists. The release also fixes a bug that prevented episode duration from displaying, an issue that prevented sharing via email, a problem that caused authentication failures for password-protected podcasts (which may require you to re-enter your credentials), and a couple of bugs associated with playback speed settings. As of this writing, the Mac App Store had not updated Downcast to version 1.0.10. ($9.99 new from the Mac App Store, free update, 6.4 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.
