Yet another reason why DRM is wrong. When a Barnes & Noble customer tried to download a previously paid-for book, an error message appeared, stating that the download had failed because the credit card on file had expired. As the cool kids say, “Epic fail.” The expiration status of a credit card for a previously purchased book should be entirely irrelevant for a later download, and to extend the scenario, there should be no requirement that the account be linked to a credit card at all after the purchase has been completed. follow link
Editing iCal Events in Snow Leopard
Snow Leopard makes looking at event details in iCal easier. In the Leopard version of iCal, you had to double-click an event to reveal only some information in a pop-up box; you then needed to click the Edit button (or press Command-E) to edit an item's information. In Snow Leopard, choose Edit > Show Inspector (or press Command-Option-I) to bring up a floating inspector that provides an editable view of any items selected in your calendar.
