iOS app developer David Barnard of App Cubby has an interesting look at the likely sales numbers behind the Sparrow email client that suggest that too-low prices in the App Store mean that it’s now extremely difficult to earn the necessary amounts of money to fund ongoing development.

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.
