Fiwix is an operating system kernel based on the Unix architecture and fully focused on being Linux compatible. It is designed exclusively for educational purposes, so the kernel code is kept as simple as possible for the benefit of students. It runs on the 32-bit x86 hardware platform, and is compatible with a good base of existing GNU applications.
The Torque Network Library is a robust, secure, and easy-to-use cross-platform C++ networking API designed for high performance simulations and games. It features a UDP- based connection architecture with DoS prevention functionality, different types of data guarantee, bit stream compression, server object replication and updating, and a simple, highly space efficient RPC mechanism. It includes a deterministic application journaling replay function for eliminating hard to find networking bugs.
The URARFileLib is a small static library that allows you to read files from RAR archives created with RAR and WinRAR. Listing, decompression, and decryption with full RAR 2.0 compatibility is done directly in your application, so there is no need for a DLL or any other external file. It is based on the free unRAR source code by Eugene Roshal, and designed for easy but powerful usage in demos and intros. It is also useful if you want to port your programs since the it is written in pure ANSI C (some parts are optimized in assembly) and supports multiple operating systems.
The GRASP Project has created an algorithmic-level graphical representation for software called the Control Structure Diagram (CSD). The CSD was created to improve the comprehension efficiency of Ada source code and, as a result, improve software reliability and reduce software costs. Since its creation, the CSD has been expanded and adapted to include other languages. GRASP provides the capability to generate CSD's from Ada 95, C, C++, Java, and VHDL source code in both a reverse and forward engineering mode with a level of flexibility suitable for professional application. GRASP has been integrated with the GNU family of compilers for Ada (GNAT) and C (gcc), and Sun's javac compiler for Java. Use of GRASP is not restricted to these compilers, however. This has resulted in a comprehensive graphically-based development environment for these languages. The user may view, edit, print, and compile source code as CSDs with no discernible addition to storage or computational overhead.
