Yum is a utility that can check for and automatically download and install updated RPM packages. Dependencies are obtained and downloaded automatically prompting the user as necessary.

zbackup is a globally-deduplicating backup tool, based on the ideas found in rsync. Any of the backup files stored previously can be read back in full at any time. The program is format-agnostic, so you can feed virtually any files to it.

Zeitgeist is a service which logs the users's activities and events (files opened, websites visites, conversations hold with other people, etc.) and makes relevant information available to other applications. It is able to establish relationships between items based on similarity and usage patterns.

The zeroer utility can be used to wipe empty space on a disk. In contrary to dd, zeroer does not wipe existing files on a partition. It overwrites the unallocated disk space around existing files, which means that deleted files cannot be restored after processing a certain partition with zeroer. The utility's principle consists in writing huge zero-padded memory blocks to a file. To a certain extent this works similar to dd, however zeroer dynamically reduces the blockwriter's buffer size when the filesystem is going to be full.

Zxfer is a fork of zfs-replicate. It allows the easy and reliable backup, restore or transfer of ZFS filesystems, either locally or remotely. Some of the features zxfer has: * Written in sh with only one dependency, rsync. Rsync mode is not used in a typical restore, hence in that situation all you need is the zxfer script, your backup and an install CD/DVD. * Reliability is first priority - the only methods of transfer allowed are those that checksum/hash the transferred data. * Transfer to or from a remote host via ssh. * Recursive and incremental transfer of filesystems (via snapshots). * Transfer properties and sources of those properties (e.g. local or inherited). * Override properties in the transfer, e.g. for archival purposes it is useful to override "copies" and "compression". * Create all filesystems on the destination as necessary. * A comprehensive man page with examples. * Can be set to beep on error or when done, useful for long transfers. * Features an rsync mode for when two different snapshotting regimes are on source and destination, and zfs send/receive won't work.

Aiksaurus is a set of libraries and applications which provide a thesaurus (currently English only, based on Guttenburg's Moby thesaurus) using native GUI on several platforms: UNIX (GTK+ & Qt), Win32 & MacOSX (Cocoa). The core library itself is platform-independent. The principal language is C++, with some use of Cocoa/ObjC++; wrappers are provided for C and Cocoa/ObjC. Aiksausus plugins exist for AbiWord on UNIX and Win32; the library is also used by Lyx; and the new Cocoa port provides a MacOSX NSService hook so that Safari and other such applications can use this thesaurus without Aiksaurus-specific development.
