Flexibits has released Fantastical 1.3.6 with the capability to use natural language to specify a calendar as you type the text of an event (previously, you could specify a calendar by using a forward slash at the beginning or end of your text). Now you can type “calendar [calendar name]” in an event string (such as “record Watchlist podcast calendar TidBITS”). The update also speeds up event updates for Microsoft Outlook users, ensures the details window doesn’t disappear during an active search, and autocompletes two-digit years (where 13 becomes 2013). ($19.99 new, free update from Flexibits and the Mac App Store, 11.2 MB, release notes)
Option-Click AirPort Menu for Network Details
If you hold down the Option key while clicking the AirPort menu in Mac OS X 10.5 Leopard, you'll see not just the names of nearby Wi-Fi networks, but additional details about the selected network. Details include the MAC address of the network, the channel used by the base station, the signal strength (a negative number; the closer to zero it is, the stronger the signal), and the transmit rate in megabits per second showing actual network throughput. If you hover the cursor over the name of a network to which you're not connected, a little yellow pop-up shows the signal strength and type of encryption.
