HTML Include solves the problem that the Hypertext Markup Language doesn't know a command for including other files into a source file. It uses specially styled comments to refer to other files, which will be inserted at this position. Unlike to the well known Server Side Include mechanism, this tool pre-processes the HTML files, resulting in files that have all referenced source files directly embedded. Thus it does not depend on any Web-server for correct appearance. As a bonus, HTML Include also writes the current date to the "last modification" line and brower meta, which you usually forget (or do not bother) to update.

These features make Hiawatha an interesting Web server for those who need more security than what the other available Web servers are offering. Hiawatha is also fast and easy to configure.
The National Space Science Data Center's (NSSDC) Common Data Format (CDF) is a self-describing data abstraction for the storage and manipulation of multidimensional data in a platform- and discipline-independent fashion. It consists of a scientific data management package (known as the "CDF Library") that allows programmers and application developers to manage and manipulate scalar, vector, and multi-dimensional data arrays.
Freesteam is a library that allows you to calculate water and steam properties using the industry-standard IAPWS-IF97 steam tables. It is a library of C++ classes which can be integrated into your code. Plug-ins to allow freesteam to be integrated with spreadsheets and other applications are under development. The included unit tests assure compliance with published property values. IAPWS-95 (scientific use) correlations are also included and used as part of this validation.
