gRustibus is a M.A.M.E. frontend for the GNOME environment. Its goal is to be feature-rich and easy to use. It shows screenshots, flyers, cabinet photos, and info for your M.A.M.E. ROMs, and allows you to configure each game individually. Most operations can be done using the keyboard.
Ghemical is a molecular modelling software package with some nice 3D visualization tools. It supports methods based on both molecular mechanics and quantum mechanics (using MOPAC7, and MPQC for QM). The geometry optimization (for MM and QM) and molecular dynamics (for MM) algorithms are included. Ghemical is written in C++, and hopefully offers a good framework for a generic freeware molecular modelling tool.
ScrudgeWare is a 100% GPL (or other freely licensed) GNU/Linux distro designed to build a simple ("bare bones") system on which the user can add any software they choose. As part of the basic framework, a system will be devised to allow users to share their customizations (or custom distros).
TEG is clone of 'Plan Tactico y Estrategico de la Guerra', which is a clone of Risk, a networked multiplayer turn-based strategy game. TEG is not fully compliant with Risk; some rules are different. It has a server, a robot, a GNOME client, support for GGZ Gaming Zone, and IPv6.
Dnsmasq is a lightweight, easy to configure DNS forwarder and DHCP server. It is designed to provide DNS and (optionally) DHCP to a small network. It can serve the names of local machines which are not in the global DNS. The DHCP server integrates with the DNS server and allows machines with DHCP-allocated addresses to appear in the DNS with names configured either in each host or in a central configuration file. Dnsmasq supports static and dynamic DHCP leases and BOOTP/TFTP for network booting of diskless machines.
