tomo3D is a multi-platform voxel-based program for the viewing and manipulation of 3D tomographic reconstructions. It offers a refined toolset to identify blurred, hardly separable 3D objects. Its tools enable global image manipulation operations as well as local manual intervention.
tpe-lkm is a Linux kernel module implementing Trusted Path Execution, a security feature that denies users from executing programs that are not owned by root, or are writable. This closes the door on a whole category of exploits where a malicious user tries to execute his or her own code to hack the system. Since the module doesn't use any kind of ACLs, it works out of the box with no configuration. It isn't complicated to test or deploy to current production systems. The module also has a few other grsecurity-inspired features implemented as "extras".
trackpeer is an agent that helps network and server administrators with tracking their users' computers. It makes it possible to determine the MAC addresses of computers over a network, even when the computers are behind NATed gateways. This agent is intended to be used by the administrators who need to identify and locate malicious computers and virus-infected computers in a network such as a middle-sized wireless LAN, public Ethernet jack system, campus, or corporate network.
Trafmetux is a network traffic meter for Linux. It tells you how much IP traffic has been seen by the Linux kernel module during the last few minutes, hours, days, weeks, and months. It's very useful when you have a limited Internet connection with quotas. For instance, many mobile broadband ISP provide only 3GB/month. In that case, you need to know how many megabytes you already used.
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.
