Fancylogin is one of the most powerful login programs available for Linux. It can do everything your old login program can do, e.g., handling shadowed passwd files, user-time-terminal/network-verification as done with HP-UX login, etc. It adds a lot of capabilities for logging logins and support for themes to control the login's look.
The Free Animation and Modeling Project (or FAMP), is a project to create a full-featured 3-Dimensional Modeling and Animation System. FAMP shall include support for animation, animated modeling. FAMP already includes the ability to extend easily without modifying code thanks to a plug-in architecture.
fam++ is a C++ wrapper for fam, which uses imon or DNotify (Linux 2.4.x) to inform it when inodes change (the net effect being that applications can register interest in a file, and have events send to the application when the file changes). Fam++ also integrates with gdk and Loki to make creation of C++ GTK+/GNOME apps simpler.
falmsg is a small utility that was designed for other sysops that are running the Falken BBS for Linux. It updates the .msg files that come with the distribution of Falken BBS, along with a few other small features. You can backup Falken BBS, restore Falken BBS, and erase the backup copy that is created using this program. falmsg is merely a front-end to a couple of other programs such as lynx, tar, telnet, and Falken BBS.
The Falcon Project (Free Application-Level CONnection kit) is an open firewall project with the intention of developing a free, secure and OS-independent firewall system. Falcon consists of three major modules: Falcons's own proxies (written in Perl); 3rd-party proxies (squid / qmail / BIND8), each modified for chroot environment; and general concepts for OS hardening, chrooting etc.
Fakeroot runs a command in an environment were it appears to have root privileges for file manipulation, by setting LD_PRELOAD to a library with alternative versions of getuid(), stat(), etc. This is useful for allowing users to create archives (tar, ar, .deb .rpm etc.) with files in them with root permissions/ownership. Without fakeroot one would have to have root privileges to create the constituent files of the archives with the correct permissions and ownership, and then pack them up, or one would have to construct the archives directly, without using the archiver.
