Cull Graphics Quickly with Preview

You're faced with a folder full of images, and you need to sort through them, trashing some number and keeping the rest. For a quick way to do that, select them all, and open them in Preview (in Leopard, at least). You'll get a single window with each graphic as an item in the drawer. Use the arrow keys to move from image to image, and when you see one you want to trash, press Command-Delete to move it from its source folder to the Finder's Trash. (Delete by itself just removes the picture from Preview's drawer.)

 
 

WPA Weakness Discovered, but Easily Solved

Send Article to a Friend

WPA Weakness Discovered, but Easily Solved -- Following last week's article about the implementation of WPA (Wi-Fi Protected Access) in AirPort Extreme cards and base stations (see "AirPort 3.2 Update Adds New Security Options" in TidBITS-704), a security expert alerted me to a weakness in choosing keys for the WPA system. The weakness applies to the AirPort 3.2 update as well as to all other consumer WPA-enabled Wi-Fi systems. Basically, choosing a key comprised entirely of real words that are 20 characters or fewer leaves you open to that key being broken rather easily. The solution? Choose a longer key or invent 20 characters of gibberish. If you're particularly security-conscious, use the option Apple provides to enter 256 bits of encryption, which is 32 hexadecimal bytes or 64 hexadecimal digits! That's overkill, however. In last week's article, it wasn't clear why Apple even offers the hexadecimal option when other devices from Buffalo and Linksys don't; now it appears that Apple provides all of the options for entering WPA keys, where the other manufacturers don't. I've written more about this issue and posted my colleague's paper on the subject at Wi-Fi Networking News. [GF]
