Panwa is a framework based on the Qt toolkit for writing platform independent applications with high quality graphical user interfaces. Panwa applications are meant as a complementary approach to Web applications, and the framework makes it possible to create applications that combine the flexibility of Web applications with the usability advantages of native applications. Therefore, you can see it as an implementation of a "rich thin client".
Petite Chez Scheme is a freely distributable interpreted version of Chez Scheme, a high-performance implementation of ANSI Scheme with numerous extensions. Petite Chez Scheme may be used as a run-time environment for compiled Chez Scheme applications or as a stand-alone Scheme system. With the exception that the compiler is not present, Petite Chez Scheme is completely compatible with Chez Scheme.
Poslib is a library which provides easy access to the Domain Name System. The client part can be used to create DNS client applications, while the server part lets you easily create a multi-threaded DNS server program, portable to many operating systems including Linux, FreeBSD, and Windows.
ProteomeCommons.org IO Framework is a proper Java framework for handling spectra and peak lists. The framework can read and write to a number of different spectra and peak list formats, and it provides a simple, intuitive Java object model for working with spectra or peak lists. All classes support two methods of handling peak list and spectrum data: in-memory or stream. The goal of this framework is to support all the popular MS and MSMS data formats, and to eliminate any time or effort involved in figuring out how to read and write peak list or spectrum files.
PyBackend is a Python module which provides object persistence through a relational database backend. You need not write SQL queries within your Python class to store or retrieve object-attributes. If your data model allows you to view attributes of your objects as columns of tables in an RDBMS, then PyBackend is for you. It allows the developer to map individual classes to corresponding databases. Hence, an application using PyBackend can use multiple databases to populate its objects; all transparently to the developer. It frees the application programmer even from the task of creating and managing database connections.
Q Engine is a cross-platform development system for games and interactive 3D applications. Its design strengths include built-in streaming, outstanding visual quality, and high-productivity development tools for deployment on Sony PlayStation 2, Microsoft Xbox, Linux, and Microsoft Windows.
QicsTable is designed to provide a high performance and more functional alternative to the QTable object included in the Enterprise and GPL versions of Qt. It is built around an MVC architecture and implemented with the philosophy that common operations (setting fonts, alignment, etc.) should be directly supported and not require additional subclasses. It is offered under two licenses: the GPL for open source efforts, and commercial for companies requiring the ability to develop proprietary applications.
Qt is a comprehensive, object-oriented development framework that enables development of high-performance, cross-platform rich-client and server-side applications. When you implement a program with Qt, you can run it on the X Window System (Unix/X11), Apple Mac OS X, and Microsoft Windows NT/9x/2000/XP by simply compiling the source code for the platform you want. Qt is the basis for the KDE desktop environment, and is also used in numerous commercial applications such as Google Earth, Skype for Linux, and Adobe Photoshop Elements.
