yeahwm (yet another h* window manager) is a minimalist window manager based on evilwm. It supports Xinerama and respects aspect size hints (useful with Mplayer and tvtime). It features creative usage of the mouse, tabbed titles that can be repositioned (BeOS-like), and good keyboard control.
zLogFabric is an all in one cross-platform logging solution that collects log lines/messages over a messaging system to a central server instance. The modular design enables the server to store, forward, alert, and generate live statistics out of the logged data. It can collect log information from files, syslog, log4j, log4net, and Windows event logs.
zap is a Perl wrapper for rm, meant be to used by the root account. It checks the list of files passed as arguments against a configuration file to make sure that root doesn't accidentally delete a protected file/directory. The root account(s) should make this script an alias for rm in their .bashrc file.
zrep provides an easy-to-use program to manage zfs filesystem replication and failover. No configuration files are required. The program is developed under Solaris, but may work with any up to date zfs implementation. The executable is a single script. Initialization does a full data copy, but subsequent syncs are incrementals. It uses internal locking to make sure there is no danger of overlap if you just shove it in cron to run every minute. Design target is more "near-time replication", since the sync can be run every minute or more. However, it could conceivably be used for "backup" purposes as well.
