Some software resources for computer science research

• The Standard Template Library for Extra Large Data Sets (STXXL) is here. Some notes are also available explaining how to install STXXL on a Linux system, and run a test program.
• Software (unix C programs, in a .tar file) for converting between geographical coordinates and Universal Transverse Mercator (UTM) coordinates. The readme.txt file is helpful in understanding how the software works.
• The TPIE (Templated Portable I/O Environment) library is a tool box providing efficient and convenient tools to ease the implementation of algorithms and data structures on very large sets of data. It is currently being maintained at MADALGO (thanks Thomas).
• The Computational Geometry Algorithms Library (CGAL) provides a C++ library for a number of 2, 3 and d-dimensional operations and data structures.
• Dia is a diagram creation program for Linux, MacOS X and Windows. It is open source, and is a great tool for design of software using UML. It can also be used to draw many other types of software design diagrams (e.g. entity relationship, flowcharts). Dia is released under the GNU General Public License, version 2.
