Two More Useful Pre-Weekend Links
by Erica Sadun
Play FLV Files in QuickTime [r00tshell]. Download and unzip the Perian component from the r00tshell page and then move it into ~/Library/QuickTime. Worked for me and so far no negative effects.
Download Aperture Updates [Apple]. You'll need an Apple ID and your Aperture serial number. Aperture 1.5 requires OS X 10.4.8
