QuantLib is a cross-platform, quantitative finance C++ library for modeling, pricing, trading, and risk management in real-life. It is also wrapped as Python/Ruby/Scheme modules. Extensions for Excel, R, and Mathematica are available. Other such extensions are under consideration. QuantLib offers tools that are useful both for practical implementation and for advanced modeling. It features market conventions, yield curve models, solvers, PDEs, Monte Carlo (low-discrepancy included), exotic options, VAR, and so on.
PhysicsFS is a library to provide abstract access to various archives. The programmer defines a "write directory" on the physical filesystem. No file writing done through the PhysicsFS API can leave that write directory, for security. For file reading, the programmer lists directories and archives that form a "search path". Once the search path is defined, it becomes a single, transparent, hierarchical filesystem. This makes for easy access to ZIP files in the same way as you access a file directly on the disk, and it makes it easy to ship a new archive that will override a previous archive on a per-file basis. Symbolic links can be disabled, for added safety. Finally, PhysicsFS gives you a platform- abstracted means to determine if CD-ROMs are available, the user's home directory, where in the real filesystem your program is running, etc.
CSDE (CSharp Development Environment for X/Emacs) is a full-featured mode for CSharp development in Emacs/XEmacs. Features include font-lock, indentation rules, grammatical parsing, auto complete, automatic documentation of classes, documentation checking of classes, namespace generation, using sorting, and much more. This is a conversion of the JDE for Emacs / XEmacs to CSharp.
mjbWorld is a standards based 3D editor, which can graphically edit and allow users to see and interact with X3D (VRML) and other 3D formats. It is also intended to provide a platform which can be used to experiment with physics, animation, etc. Versions for Java, C++ and C# are included.
UnicodeConverter is a Java/Windows/.NET program that converts text, RTF, HTML, and Word/Excel documents in Vietnamese legacy encodings such as VNI, VPS, VISCII, TCVN3 (ABC), VIQR/Vietnet NCR (windows-1252, iso-8859-1), and Unicode Composite (Decomposed or NFD) to Unicode Precomposed (NFC) format.
SOAP Anywhere is a SOAP 1.2 implementation written in Java. The difference between SOAPAnywhere (SAW) and Implementations such as Apache SOAP and Axis is that SAW can not only be run through a WebAPP container, but can also run in both a standlone mode and as an integrated component of any Java application.
