Trojan Scan is a simple shell script that allows for simple but relatively effective checking for trojans, rootkits and other malware that may be using your server and network for unwanted (and possibly illegal) purposes. It is relatively simple and won't catch them all, but can help to find these programs on shared servers with many users. It works by listing all process that use the Internet with the lsof command (using -Pni flags). This list is then transformed into signatures, which are then are matched against the allowed process defined in the configuration. If any signatures of running processes are found that do not match the allowed signatures, an email report is sent including ps, ls, and optional lsof output for the unknown processes.
KitCreator is a simple build system for creating a Tclkit. It was created to ease creation of Tclkits. A Tclkit is, briefly, a single-file executable that contains Tcl (both the interpreter and all the resources it requires to operate) and other Tcl-related packages (such as Tk or Incr Tcl).
Libpsl is a C library which provides functions to check domains against the Mozilla Public Suffix List.

Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. It provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. Individuals can use it to keep remote Websites from tracking them and their family members. They can also use it to connect to resources such as news sites or instant messaging services that are blocked by their local Internet service providers (ISPs).
Marvin is an extensible image processing framework for Java. It provides features to manipulate images, to manipulate captured video frames, and to process images with multi-threading. Its features can be extended via plug-ins. Plug-ins can be integrated with the graphical user interface, and their plug-in performance can be analyzed. Every image processing algorithm is developed as a plug-in that can be plugged into the MarvinEditor, an image manipulation program that uses plug-ins developed using Marvin, or into third-party applications. Currently there are 55 plug-ins available.
