The ATLAS (Automatically Tuned Linear Algebra Software) project is an ongoing research effort focusing on applying empirical techniques in order to provide portable performance. It provides C and Fortran77 interfaces to a portably efficient BLAS implementation, as well as a few routines from LAPACK.
The mission of the Apache Portable Runtime (APR) project is to create and maintain software libraries that provide a predictable and consistent interface to underlying platform- specific implementations. The primary goal is to provide an API to which software developers may code and be assured of predictable if not identical behaviour regardless of the platform on which their software is built, relieving them of the need to code special-case conditions to work around or take advantage of platform-specific deficiencies or features.
C Scripting Language (CSL) is an embeddable scripting language with C syntax. A comprehensive set of libraries is included in the base package, and writing your own libraries is possible with an easy API for C programs, as well as a class interface for C++ programs. If you are looking for a compact and powerful scripting engine for your application, CSL might be the choice.
CodeBase is a high-speed xBASE compatible database engine for C/C++, Visual Basic, Delphi & Java programmers. You can use CodeBase to write high performance database applications that are multi-user compatible with FoxPro, dBASE and Clipper, create anything from a Java applet to a full-blown Windows database application to a simple DOS utility, write scalable applications that can be deployed as single-user, multi-user or client/server, all without changing any of your source code, and port your applications to Windows, DOS, UNIX, OS/2, and Macintosh. There's a free 30-Day Test Drive option available. CodeBase is available for every major operating system including Windows XP, 2000, 9x, NT, CE, DOS, OS/2, Macintosh, and a variety of Linux and UNIX platforms including Solaris, SunOS, HP/UX, AIX, SCO, and others.
The EJBWizard is a graphical tool written in Java to assist in the rapid prototyping on Enterprise Java Beans (EJBs) and JavaServer Pages (JSPs) that manipulate them. Originally designed to work with the JOnAS EJB server system, the EJBWizard has been expanded to create beans suitable for use with virtually any EJB server system.
The Extended Universal Resource Locator library provides a complete virtualization of file-like objects. How data is stored is completely transparent to the client, since the library is meant to replace java.io.File. It provides implementations for handling local files, Jar/Zip archives, and XML documents. (Implementations for CVS and FTP are available seperately.) Other storage providers can be written and plugged in. It also provides a merged filesystem implementation that allows multiple hierarchies to appear as one and to override each other in a controlled way. Other features include notification of changes to files, and support for attaching (dynamically updatable) actions to file objects.
