Amazon has created a Web app version of its Kindle reading software for Safari for the iPad, Mac OS X, and Windows, and Chrome for desktops. The app uses HTML5 to mimic the natively written Kindle apps, and does a quite decent job. Amazon leverages HTML5 local storage support to download Kindle titles to the browser, too. This is seen as a workaround by Amazon to bypass Apple’s 30-percent cut of media purchase fees in iOS apps. follow link
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.
