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
Access OpenType Font Features
OpenType fonts (.otf) often have special features, such as swashes and alternate characters, that are accessible in any app that uses the OS X font panel, including Pages and TextEdit. To access them, type and select your text, press Command-T to open the font panel, and then choose Typography from the Actions pop-up menu. That shows the Typography panel, where you can toggle available options for the font and characters you've selected.
