Gentle.NET is a CLS-compliant, database independent object persistence framework. It has an extensive feature set, excellent performance, and reasonably complete docs. It features automatic SQL generation, object construction/caching/uniquing, validation, bindable list support, relation management, transactions, and much more. Oracle, PostgreSQL, MySQL, Firebird/InterBase, MS SQL Server (incl. CE), MS Access, SQLite, Sybase, and Sybase ASA are supported. It includes a NAnt build file as well as VS.NET project files for building under Windows. Mono 1.1.4 and higher is fully supported.
JUCE is an all-encompassing C++ class library for developing cross-platform applications. It's particularly good for creating highly-specialised user interfaces and for handling graphics and sound. The intended users are developers who are building large, complex applications in C++ and who would like to use just one clean, high-level API rather than a bunch of different libraries for different purposes or platforms. Its features include fully lightweight components with transparency and effects, classes for strings, containers, XML, streams, file handling, messaging, and event queues, vector graphics, a custom font engine, image manipulation, OpenGL support, low-latency audio I/O using CoreAudio, DSound and ASIO, audio buffers and nodes, MIDI file and event manipulation, Internet streams, undo/redo support, and more.
Webware for Python is a suite of Python packages and tools for developing object-oriented, Web-based applications. The suite uses well known design patterns and includes a fast Application Server, Servlets, Python Server Pages (PSP), Object-Relational Mapping, Task Scheduling, Session Management, and many other features. Webware is very modular and easily extended. It is well proven and platform-independent. It is compatible with multiple Web servers, database servers, and operating systems.
crypt_blowfish is an efficient implementation of a modern password hashing algorithm, based on the Blowfish block cipher, provided via the crypt(3) and a reentrant interface. It is compatible with bcrypt as used in OpenBSD. It is adaptable to future processor performance improvements, allowing you to arbitrarily increase the processing cost of checking a password while still maintaining compatibility with your older password hashes. The hashes it produces are several orders of magnitude stronger than traditional Unix DES-based or FreeBSD-style MD5-based hashes.
CGI::Application is a Perl framework intended to make it easier to create sophisticated, reusable Web-based applications. This module implements a methodology which can make Web software easier to design, easier to document, easier to write, and easier to evolve. CGI::Application builds on standard, non-proprietary technologies and techniques, such as the Common Gateway Interface and Lincoln D. Stein's excellent CGI.pm module. CGI::Application judiciously avoids employing technologies and techniques which would bind a developer to any one set of tools, operating system, or Web server.
phpSecureSite is a modular authentication, session handling and security system for Web applications that was built using PHP. It features a stripped-down core that takes care of basic session handling, and modules for other functionality like brute force protection, session variables, and access control lists.
