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.
Quassel IRC is a modern, cross-platform, distributed IRC client, meaning that one or more clients can attach to and detach from a central core, much like the popular combination of screen and a text-based IRC client, but graphical. In addition to this unique feature, it aims to be a comfortable chatting program.
cmogstored is an alternative, C implementation of the "mogstored" storage daemon used for MogileFS storage nodes. This implementation allows MogileFS storage nodes to be deployed with a minimal memory/filesystem footprint with no additional runtime dependencies. This implements all HTTP/1.1 DAV functionality needed by MogileFS clients as well as the mogstored stream protocol. This project is still in the early stages of development and not directly affiliated with the MogileFS project.
SaVi is satellite visualization software that lets you create, run, examine, and modify satellite orbits in two and three dimensions. Simulations of Iridium, Globalstar, Galileo, GPS, and other satellite constellations are included. SaVi requires Tcl and Tk on a system with Unix libraries. SaVi works well with the 3D renderer Geomview. Geomview is optional, though recommended for its 3D rendering capabilities.
UrBackup is an efficient client/server backup system for Linux and Windows. A client for Windows lets you backup open files and complete partition images. Incremental and full image backups are stored to disk in a efficient way with file level de-duplication on either Windows or Linux servers. An easy-to-use server Web interface lets you analyze storage usage, view logs, modify settings, and browse backups. Backup images can be restored using a prebuilt live Linux CD based on KNOPPIX.
