Ambrosia has released Snapz Pro X 2.5.2 to fix an issue with accurately capturing the precise pixels of a selection and bring back support for several styles of image borders (which was excised in version 2.5). The update also improves the reliability of movie encoding, improves compatibility with both OS X 10.8 Mountain Lion and Retina displays, and adds Chinese and Russian localizations.

Type an em-dash on an iPhone
Typography and punctuation geeks rejoice! It's easy to type an em-dash on the iPhone's or iPod touch's virtual keyboard. To do so, tap the .?123 key to switch to the numeric keypad. Then touch and hold on the Hyphen key to reveal a pop-up strip showing an em-dash. Slide to the em-dash and release your finger.
Note that this basic trick works with many other keys on the virtual keyboard.
