Permanent Eraser… When you normally delete your files in Mac OS X, the operating system is only forgetting where those particular files are placed, while the data still physically remains on the drive. Beginning with Mac OS 10.3, Apple enhanced its security by introducing the Secure Empty Trash feature, which follows the U.S. DoD pattern of overwriting data seven times.

Permanent Eraser provides an even stronger level of security by implementing the Gutmann Method. This utility overwrites your data thirty-five times, scrambles the original file name, and truncates the file size to nothing before Permanent Eraser finally unlinks it from the system. Once your data has been erased, it can no longer be read through traditional means.  

Permanent Eraser is free of charge, and the source code is also provided for educational purposes.

Sidenote tries to catch the “Stickies” spirit but in the form of a multi-document drawer that will hide in the corner of your screen (left or right). You can use it to take all your daily notes, include images and easily modify text color and font. Sidenote will automatically expand so that you will be able to drag into it any picture, text clipping or pdf file from the finder or your favorite application. Sporting notes auto-saving, you’ll never have to save your notes. Sidenote will handle that for you. You can also print them or export them to rtf.
