Treba is a commandline tool for training, decoding, and calculating with weighted (probabilistic) finite state automata (WFSA/PFSA). Training algorithms include Baum-Welch (EM), Viterbi training, and Baum-Welch augmented with deterministic annealing. Treba is optimized for speed and numerical stability, and training algorithms can be run multi-threaded on hardware with multiple cores/CPUs. Forward, backward, and Viterbi decoding are supported. Automata for training/decoding are read from a text file, or can be generated randomly or with uniform transition probabilities with different topologies (ergodic or fully connected, Bakis or left-to-right, or deterministic). Observations used for training or decoding are read from text files compatible with AT&T finite state tools and OpenFST.
Cretan Hubris is an infinite maze escape game set in ancient Greece. As the master architect Daedalus, having just completed the Labyrinth, you must now escape your creation while staying ahead of a deadly energy wave sent by petty and jealous gods. Features include customizable controls, joystick support, and sound effects.
AbulEdu Calcul Mental is a software tool that trains children in mental calculation as stipulated by the French Ministry of Education for primary schools. Activities include addition, subtraction, multiplication of integers, addition tables (+2 to +9), times tables (x2 to x9), additional additives (to 10, to 100, to 1000), multiples (of 5, 10, 15, 20, 25 and 50), and orders of magnitude (with additions, subtractions, and multiplications). There is also an editor and selective launcher.
gpfcalc is a GTK+ front-end for pfcalc, a pipe friction calculator using the Darcy-Weisbach equation. It computes major, minor, and static losses for flow through pipes or ducts. Up to 1024 pipes or ducts can be defined by specifying hydraulic diameter, length, roughness, flow rate, temperature, and elevation change. Data can be saved in a comma separated values file (CSV) and imported in the spreadsheet program of your choice for further processing.
Inguma is a penetration testing and vulnerability research toolkit. The framework includes modules that discover hosts, gather information, fuzz targets, brute force user names and passwords and attempt exploits. While the current exploitation capabilities are limited, the program provides numerous tools for information gathering and target auditing.
Parrot and Chirp are user-level tools that make it easy to rapidly deploy wide area filesystems. Parrot is the client component: it transparently attaches to unmodified applications, and redirects their system calls to various remote servers. A variety of controls can be applied to modify the namespace and resources available to the application. Chirp is the server component: it allows an ordinary user to easily export and share storage across the wide area with a single command. A rich access control system allows users to mix and match multiple authentication types. Parrot and Chirp are most useful in the context of large scale distributed systems such as clusters, clouds, and grids where one may have limited permissions to install software.
bscallmon is a small GUI tool that allows you to view the list of incoming and outgoing phone calls on routers running the BitSwitcher firmware without having to log into the router's Web interface. Features include a phone book, custom icons, unlimited call list size, and optional systray integration and call notification. It does not require compiling and runs on both Unix and Windows systems.
