The stmpclean utility removes old files (and old empty directories) from the specified directory. It is meant to be used to clean directories such as "/tmp" where old files tend to accumulate. stmpclean never removes files or directories owned by root, which is a feature, not a bug. Great care is taken while descending into the directory, and the operation is secure. Anything that's not a directory, regular file, or symbolic link is also left alone (because programs like screen(1) create sockets and FIFOs under /tmp and expect them to be long-lived). Unlike other programs that do the same task, stmpclean never forks and consumes limited amount of memory. If stmpclean determines a race condition it will log the situation and exit with a failure.
Agar is a toolkit for graphical applications. It features a modern GUI system with an unobtrusive API. Agar can use different graphics interfaces, such as SDL and OpenGL, and it has been ported to numerous platforms, including game consoles and embedded systems. Agar is implemented in C, but can be used from other languages.
Open1x is an open source implementation of the IEEE 802.1x protocol. The project has two components: xsupplicant and authenticator. Xsupplicant is an implementation of the supplicant (i.e., client) side of the protocol and works under Linux and Mac OS X. Authenticator is an implementation of the authenticator and works only under Linux.
ShoStats is a reimplementation of phpSysInfo in Perl, useful for running from crontab and outputting the stats to a PHP include file, which can then be displayed on a hosting account. It is modular and configurable, including modules to support both Linux, OpenBSD, and NetBSD, an output module for PHP include files, and transfer modules for output to stdout (which can be redirected or piped) and uploading to an FTP server.
Rocks is a complete "cluster on a CD" solution for x86 and IA64 Red Hat Linux COTS clusters. Building a Rocks cluster does not require any experience in clustering, yet a cluster architect will find a flexible and programmatic way to redesign the entire software stack just below the surface (appropriately hidden from the majority of users). Although Rocks includes the tools expected from any clustering software stack (PBS, Maui, GM support, Ganglia, etc), it is unique in its simplicity of installation.
