BlackHole is an data de-duplicating network block device that also supports mirroring, snapshots, and support for multiple LUNs using the same data store. It is filesystem agnostic and has been tested with ext2/3/4, NTFS, ReiserFS, and the Oracle Cluster File System (OCFS2). It supports encryption, compression, and multiple storage backends. The hashing scheme used is user configurable. The program exports an NBD device which can be mounted in Linux and GNU/Hurd.
GloboNote is a desktop note taking application. It helps you to create to-do lists, reminders, and other notes in one place. There is no limit in the number of sticky notes you can create. Notes can be organized by groups and searched using the search tool. You can format a note's text, change its color, font, size, and transparency level. You can make a note sticky by setting it to always stay on top, or hide or roll-up a note when not use. You can set alarms, play custom alarm sounds (WAV, MP3, AIFF, and AU), attach files, insert images, and more.
