Copy Disk Image as Folder

When you open a .dmg file, a disk image is mounted. You are then generally supposed to copy the contents of that disk image to your hard drive (to your Desktop, your Applications folder, or wherever). But what if you want to copy the whole disk image, including all its contents, as a folder? Hold the Option key, and drag the "proxy icon" in the title bar of the disk image window to the destination in the Finder.

If you haven’t been listening to iTunes Store previews recently, you might not have realized that they’ve largely been extended from 30 seconds to 90 seconds. And you’ll spend a lot more than 90 seconds reading Michael Mace’s fascinating explanation of why Apple is beating RIM, and how computing platforms die.

iTunes Store Offers 90-second Song Previews -- Lex Friedman writes at Macworld about how Apple has now modified the U.S. iTunes Store to play 90-second previews of songs longer than two-and-a-half minutes; that’s up from 30 seconds. According to Lex, not all songs have the new previews yet, and the longer previews are limited to the U.S. iTunes Store, presumably due to licensing restrictions in other countries. Still, 90 seconds is much better for getting a sense of a song. Oh, and look carefully at the screenshot; 90 seconds should be more than enough to get a sense of that piece!

It’s a few months old, but well worth reading for an insider’s view of how large technology companies can succeed or fail.
