Liblouis is a Braille translator and back-translator. It features support for computer and literary braille, supports contracted and uncontracted translation for very many languages, and has support for hyphenation. New languages can be added easily through tables that support a rule based or dictionary based approach. It also includes tools for testing and debugging tables. Liblouis also supports math Braille (Nemeth and Marburg). The formatting of Braille is provided by the companion project liblouisxml. Liblouis has features to support screen-reading programs.
Fakeroot-ng runs a program while fooling it into thinking it is running with root privileges. When the program does something that only root can do (e.g. create a device file), fakeroot-ng emulates the appropriate system calls so that the program gets a consistent view of its actions. Unlike the original fakeroot, fakeroot-ng uses the ptrace interface, which means that it does not suffer some of the limitations that fakeroot does. In particular, fakeroot-ng supports chroot jails.
dbacl is a digramic Bayesian text classifier. Given some text, it calculates the posterior probabilities that the input resembles one of any number of previously learned document collections. It can be used to sort incoming email into arbitrary categories such as spam, work, and play, or simply to distinguish an English text from a French text. It fully supports international character sets, and uses sophisticated statistical models based on the Maximum Entropy Principle.
CellWriter is a grid-entry natural handwriting input panel. As you write characters into the cells, your writing is instantly recognized at the character level. When you press 'Enter' on the panel, the input you entered is sent to the currently focused application as if typed on the keyboard. Writer-dependent, CellWriter learns your handwriting for reliable recognition. Correcting preprocessor algorithms account for digitizer noise, differing stroke order, direction, and number of strokes. Unicode support enables you to write in any language.
Japha is an effort to implement the major functionality of the Java library in PHP. The functionality captured in the JPI includes I/O, utility classes such as data structures, Web service architecture, and reflection classes, lang classes for implementing a standardized API, bean classes for creating a standard bean implementation, SQL classes for database persistence (via the Web service architecture), and database abstraction as well as Object-Relational mapping, networking functionality, and even some complex math.
