STklos is a free Scheme System conforming to R5RS. The implementation is based on an ad-hoc Virtual Machine. It can also be compiled as a library, so that one can easily embed it in an application. Its features include an efficient and powerful object system based on CLOS, a simple-to-use module system, implementation of the full tower of numbers defined in R5RS, and easy connection to the GTK+ toolkit. STklos is the successor of STk, a Scheme interpreter tightly connected to the Tk toolkit.
Scintilla is a free source code editing component for Win32 and GTK+. As well as features found in standard text editing components, Scintilla includes features especially useful when editing and debugging source code. These include support for syntax styling, error indicators, code completion and call tips. Styling choices are more open than with many editors, allowing the use of proportional fonts, bold and italics, multiple foreground and background colours and multiple fonts.
SPTK (Simply Powerful Toolkit) is a cross-platform toolkit that provides a set of C++ classes for fast and easy application development. It provides GUI components that use FLTK, and features database support with seamless connection to GUI components. There are drivers for use of SQLite and PostgreSQL directly, as well as support for other database engines through UnixODBC. SPTK includes many classes for working with strings, dynamic arrays, and maps, and is faster and has a smaller footprint than STL. It also supports reading, writing, and creating Excel 7 files, high-level GUI components with dataset support, support for automatic layouts, and support for Aspell.

The edit-on JavaBean SDK is a customizable, feature-rich JavaBean that allows developers to add WYSIWYG editing functionality to their AWT- or Swing-based applications. It features an intuitive word processor-like user interface that enables XHTML content authoring with XML markup, and has a royalty free run-time license.
SetiContainer is a C++ class that allows convenient access to all the information in the state files of a SETI@home client. It periodically examines these files and updates its own data members accordingly. Other programs can use this class to extract information about the progress of the client, the found signals, or the work unit being processed. Additional functions offer more advanced info (like the amount of TeraFlops in a work unit, estimated time of completion, etc.). The SetiContainer class is based on the Qt toolkit, and extensively uses Qt's Signal/Slot technique.
