tn5250 is a 5250 terminal emulator, used for connecting to IBM's AS/400 (now known as eServer iSeries) midrange computers. tn5250 implements TN5250E, which means it is capable of device name selection, and printer sessions. The emulator supports color, 132 column mode, and most other features found in 5250 terminals and Client Access' 5250 emulator. While tn5250 is text-based application, a script is included to run it in an xterm properly. If you don't know what an AS/400 is, this program will probably not be of much use to you.
tokengrid is a PHP class that can be used to generate a grid of tokens to authenticate users. Such a grid is similar to those that banks provide to users to avoid account abuses after phishing attacks. It generates a bidimensional array of tokens of limited length with letters and digits. The generated grid is seeded by a given secret salt string and a specific id that may be used to generate unique grids for different applications and users. The class may also verify whether a token entered by the user corresponds to a token of a random grid position.
Trad4 is a fully concurrent, thread safe, graph based programming language that scales linearly on multiple cores. It is initially intended for deployment in the financial industry to model real-time risk. Trad4 is proposed as an alternative to the Von Neumann model of computer architecture. It is a new way of arranging programs in memory and a new style of flow-of-control.
