Net::Z3950::SimpleServer is a Perl module which implements the server side of the Z39.50 (information retrieval) protocol. It hides the complexity of network exchanges, packet serialization, and session handling. You are required only to implement simple callbacks to support searching and record retrieval. It is the basis of the "Zoogle" project, which is a Z39.50 gateway to the Google web index.
The Texttools packages are an ncurses-based library for the Linux console written in Ada 95. It contains more than 600 procedures and functions to create windows, draw scroll bars, handle the mouse and keyboard events, play sounds, and much more. It also provides a thick binding to Linux kernel calls. You can create a wide variety of application programs using Texttools alone.
RTEMS (Real-Time Executive for Multiprocessor Systems) is a commercial grade real-time operating system designed for deeply embedded systems. It is a free (as in beer and speech) open-source solution that supports multi-processor systems. RTEMS is designed to support applications with the most stringent real-time requirements while being compatible with open standards such as POSIX. It includes filesystem support as well as a port of the FreeBSD TCP/IP stack. It's been ported to numerous processor architectures including ARM, Blackfin, PowerPC, i386, M68K, Coldfire, MIPS, Mico32, M32C, M32R, NIOS2, SPARC, SH, H8, and C3x/C4x DSPs. Using the GNU tools for cross development, you can use any number of systems as development hosts including both Unix and Windows platforms. There are pre-built cross development toolsets for RPM-based GNU/Linux distributions and MS Windows.
Fuzzy sets for Ada is a library providing implementations of confidence factors with the operations not, and, or, xor, +, and *, classical fuzzy sets with the set-theoretic operations and the operations of the possibility theory, intuitionistic fuzzy sets with the operations on them, fuzzy logic based on the intuitionistic fuzzy sets and the possibility theory; fuzzy numbers, both integer and floating-point with conventional arithmetical operations, and linguistic variables and sets of linguistic variables with operations on them. String-oriented I/O is supported. A rich set of GTK+ GUI widgets is provided.
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.
