translucency is a loadable kernel module for Linux that virtually merges two directories, making it possible to overwrite files on read-only media and compile projects (such as the Linux kernel) with different options without copying sources each time. No user-space tools have to be changed. The process is also known as inheriting (ifs), stacking, translucency (tfs), loopback (lofs), and overlay (ovlfs).
trapdoor2 allows remote users to execute local commands by sending 'magic cookies'. this can e.g. be used to alter local firewalling rules so people can connect to local services after sending the magic cookie. trapdoor2 is implemented as a high-secure HTTPS server and includes support for the Wireless Application Protocol (WAP).
trash-cli is a command line interface to the FreeDesktop.org trashcan. It implements the FreeDesktop.org trash specification. For each trashed file, it will remember the name, original path, date of deletion, and permissions. It interoperates with KDE and GNOME Trash, and is CLI compatible with the rm command.
travtrack is a tool to help a Traveller(tm) referee keep track of essential data for a game. Already implemented are galaxies, sectors, subsectors, systems, stars, planets, belt and moons. Yet to be implemented are trade routes, ships, characters, and all the rest. These will take some time, but should not be too complex. It currently uses the GURPS Traveller:First In rules for system generation, but a subproject is under way to add Classic Traveller generation and output. travlib is a collection of C routines that should make writing a Traveller application easier. A guile interface to the data representation functions is provided.
Treeps is program for Unix/Linux that is designed to make monitoring and interacting with the running programs on your system easy and intuitive. A "real time" tree view shows the relationships between the processes and is color-coded to provide easy interpretation of various values. The process tree displays any combination of users/groups and can be used to drill down into process details and then extract key fields for continuous monitoring. A number of actions can be performed on processes, such as signal, renice, trace, view man page, etc.
