Microsoft has released Skype 6.15, which fixes two instances of crashes (one at launch and one when quitting) that were identified thanks to users in Skype’s Community Forums. The update also fixes a bug that prevented per-conversation notification settings from sticking and an issue with animated emoticons using too many CPU cycles. Finally, the release also eliminates crashes when screen sharing on a MacBook Pro (with the associated recommendation that MacBook Pro users also update to OS X 10.9.2 Mavericks).

Spacebar Magnifies Photos in iPhoto '08
In iPhoto '08, you can choose whether double-clicking on a photo will edit it or magnify it. I prefer my double-clicks to edit photos, but every now and then it's nice to magnify a photo. To do that, even when double-click is set to edit, just select the photo and press the Spacebar.
