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]

iMovie '09: Speed Clips up to 2,000%
iMovie '09 brings back the capability to speed up or slow down clips, which went missing in iMovie '08. Select a clip and bring up the Clip Inspector by double-clicking the clip, clicking the Inspector button on the toolbar, or pressing the I key. Just as with its last appearance in iMovie HD 6, you can move a slider to make the video play back slower or faster (indicated by a turtle or hare icon).
You can also enter a value into the text field to the right of the slider, and this is where things get interesting. You're not limited to the tick mark values on the slider, so you can set the speed to be 118% of normal if you want. The field below that tells you the clip's changed duration.
But you can also exceed the boundaries of the speed slider. Enter any number between 5% and 2000%, then click Done.
