The GNU Gatekeeper is a free H.323 gatekeeper based on the OpenH323 project. You can use it to manage a Voice-over-IP network and let endpoints (e.g., Netmeeting) communicate through symbolic names. It also has an external interface for billing and other applications. It runs on a number of Unix versions (including Linux and Solaris) and Windows.
The Lightweight Java Game Library is a native binding for OpenGL and OpenAL written with game developers in mind. It allows the full OpenGL and OpenAL APIs to be exposed without the penalties associated with competing methods, nor the limitations of APIs such as Java3D. Tutorials and demos are available, and Windows, Linux, and Mac OS X are supported.
Concurrency Kit provides a plethora of concurrency primitives and lock-less and lock-free data structures designed to aid in the design and implementation of high performance scalable concurrent systems. It was designed to minimize dependencies on operating system-specific interfaces, and most of the interface relies only on a strict subset of the standard library and more popular compiler extensions.
BORG is a calendar and task tracking system written entirely in Java. The calendar is an appointment organizer that provides a nice month view, month printing, email reminders, popup reminders, and a to do list. The task tracker tracks issues and tasks through various user-defined states.
libextractor is a library used to extract meta-data from files of arbitrary type. It is designed to use helper-libraries to perform the actual extraction, and to be trivially extendable by linking against external extractors for additional file types. The goal is to provide developers of file-sharing networks, file managers, and WWW-indexing bots with a universal library to obtain meta-data about files. It includes a shell-command and bindings for Java (JNI) and Python.
Webdata Pro creates relational database solutions online, and requires no technical, programming, or SQL knowledge. It runs on any server that has MySQL. While many have mastered the HTML skills necessary to publish a Web page, integrating a database into a Web site remains a daunting task for most non-programmers. Webdata Pro solves this problem. Its Web interface provides the administrator a point-and-click path through building tables, designing search pages/reports/forms, managing records, and defining member accounts. All functions are accessed through a browser with simple, non-technical instructions. It has a built-in shopping cart, and can easily import data from other programs and upload images or documents through the browser. The program has powerful member privileges, allowing the administrator to control each member's access to the data. Calculation fields such as SUM, AVG, COUNT, ESCAPE, IF-ELSE, and more are included. Further, the software creates complex JOIN queries automatically. The administrator just selects the fields and Webdata Pro does the rest. It is designed with speed in mind, and is able to search millions of records quickly. Individually customized reports and forms can be generated using any HTML editor.
ObjectDB for Java/JDO is a powerful yet compact Java Data Objects (JDO) Object Database (ODBMS), written entirely in Java, and compliant with the Java Data Objects (JDO) standard developed by Sun (JSR12). ObjectDB for Java/JDO is designed to efficiently handle databases of various sizes, ranging from a few KBs to hundreds of GBs. Among its features are small footprint, high performance, rapid development, easy deployment, and flexible architecture (1-Tier, 2-Tier, or N-Tier).
