The project Ada Bar Codes provides a framework for generating various types of bar codes (1D, or 2D, like QR codes) on different output formats and devices.

The library provides an implementation of dimensioned values for Ada. Unit checks are made at run-time, if not optimized out by the compiler. SI and irregular measurement units are supported. Shifted units like degrees Celsius are supported too. Conversions from and back to strings are provided for all various irregular units. An extensive set of GTK widgets for dealing with dimensioned values is included, though use of GTK is not mandatory for the rest of the library.
Corlpack consists of a library and tools aiming to simplify and accelerate programming of small, scientific, computational applications.
One of the planned features is the loading and saving of a variety of research data into a single generic data structure, that is much like the named list from R, thus removing the need to learn many data access APIs.
