TLA Systems has released PCalc 4, rewritten from the ground up to resemble its iOS sibling. The latest version of the powerful Mac calculator includes a number of new features, such as the capability to show multiple lines on the display; a “ticker tape” option to show a history of recent calculations; editable user functions and conversions that sync to iOS and other Macs via iCloud; smart searching for conversions, constants, and functions; enhanced AppleScript support; and more. PCalc 4 requires OS X 10.8 Mountain Lion and is a free update for both Mac App Store users and those who purchased PCalc 3 from Kagi after 1 April 2013. It’s now being sold exclusively through the Mac App Store. ($9.99 new on the Mac App Store, free update)
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.
