Spinneret is a structured storage engine that can be thought of as an extended tuple storage system. It takes the best aspects of relational, object, and hierarchical databases and throws away the dead weight associated with those technologies. The benefit of Spinneret is that its data model is incredibly flexible, allowing it to expose its underlying data in any number of ways. It operates similar to an object database, but without hard ties to an originating language, and can also behave like a relational database without the burden of complex joins.
DEMUX Framework enables Java developers to build modular, cross-platform applications which can run on desktop, Web, and mobile and embedded devices. It is based on OSGI and supports creating JavaFX desktop applications, mobiles apps (Android, iOS, Windows), and Web applications.
ClodHopper is a Java library for high-performance clustering of numerical data. It contains clustering implementations such as K-Means, K-Means++, X-Means, G-Means, Fuzzy C-Means, Jarvis-Patrick, and various forms of hierarchical clustering. ClodHopper's clustering implementations take advantage of the host system's concurrent processing ability to speed clustering. The data structures are also very lean to conserve memory usage. ClodHopper is very extensible. If you are developing a new clustering algorithm, you may save yourself an enormous amount of work by extending a ClodHopper base class.
BitNami Moodle Stack is an easy-to-use installer for Moodle, which is a course management system that is designed using sound pedagogical principles to help educators create effective online learning communities. It can scale from one computer to a 50,000-student university and is used in 175 countries around the world.
ContiPerf is a lightweight testing utility to easily leverage JUnit 4 test cases as performance tests, e.g. for continuous performance testing. It is inspired by JUnit 4's easy test configuration with annotations, and by JUnitPerf's idea of wrapping Unit tests for performance testing, but is more powerful and easier to use. It uses Java annotations for defining test execution characteristics and performance requirements. You can mark a test to run a certain number of times, or to be repeatedly executed for a certain amount of time. Performance requirements can be maximum, average, medium, or any percentile execution time. You can run tests in two different modes, using them as simple unit tests or performance tests. Easy integration with Eclipse and Maven. Export of an execution summary to a CSV file. A small library without external dependencies (only JUnit).
jrawio is a Service Provider Implementation for the Java Image I/O API that provides the capability to read images stored in a "camera raw" format. It supports various formats from the major camera manufacturers (e.g. NEF, CRW, CR2, PEF, SRF, MRW) as well as Adobe Digital Negative Format (DNG). It is made of pure Java code and does not require any native library.
Ametys is a powerful Web CMS used by many institutions of higher education and government, but also industries and SMEs. It is known for its ergonomic design which promotes ease of use, its social Web functionality, and the ability to manage a large number of users. It makes content publishing accessible for the non-programmer and provides an easy editorial interface very similar to Microsoft Office applications.
