Over at Macworld, Lex Friedman explains how to turn on and use two-factor authentication with a Google account to combine a fixed password with a constantly updated additional code sent as a text message or accessible from a smartphone app. Be aware that two-factor authentication may be more trouble than it’s worth, depending on how often you need to sign into your Google account. follow link
Opening a Folder from the Dock
Sick of the dock on Mac OS X Leopard not being able to open folders with a simple click, like sanity demands and like it used to be in Tiger? You can, of course click it, and then click again on Open in Finder, but that's twice as many clicks as it used to be. (And while you're at it, Control-click the folder, and choose both Display as Folder and View Content as List from the contextual menu. Once you have the content displaying as a list, there's an Open command right there, but that requires Control-clicking and choosing a menu item.) The closest you can get to opening a docked folder with a single click is Command-click, which opens its enclosing folder. However, if you instead put a file from the docked folder in the Dock, and Command-click that file, you'll see the folder you want. Of course, if you forget to press Command when clicking, you'll open the file, which may be even more annoying.
