BERT and BERT-RPC are an attempt to specify a flexible binary serialization and RPC protocol that are compatible with the philosophies of dynamic languages such as Ruby, Python, PERL, JavaScript, Erlang, Lua, etc. BERT aims to be as simple as possible while maintaining support for the advanced data types we have come to know and love. BERT-RPC is designed to work seamlessly within a dynamic/agile development workflow. The BERT-RPC philosophy is to eliminate extraneous type checking, IDL specification, and code generation. This frees the developer to actually get things done. - Darth Medved

Krati is a simple persistent data store with very low latency and high throughput. It is designed for easy integration with read-write-intensive applications with little effort in tuning configuration, performance and JVM garbage collection. This software is published under the terms of the Apache Software License version 2.0, a copy of which has been included in the LICENSE file shipped with the Krati distribution. - Darth Medved

Hypertable was designed for the express purpose of solving the scalability problem, a problem that is not handled well by a traditional RDBMS.  While it is possible to design a distributed RDBMS system by breaking the dataset into shards, this solution requires an enormous amount of engineering effort and the resulting system will have inherent weaknesses because the core database engine was not designed for scalability.  Hypertable is based on a design developed by Google to meet their scalability requirements and solves the scale problem better than any of the other NoSQL solutions out there. - Darth Medved

Java Kohonen Neural Network Library is a set of classes and functions for design, train and use Kohonen network (self organizing map). - Darth Medved

Inspired by Alexandru Popescu's blog post about running Groovy scripts as JMeter samplers. This project uses JMeter's bean plugin architecture to create a simple sampler that runs any arbitrary Groovy script. To use this plugin, just simply drop in the JAR to your JMETER_HOME/lib/ext directory and you're all set. Email with any questions, submit defects for improvements, or let me know if you'd like to contribute code to the project. All the best, -Matthew McCullough - Darth Medved

ReflectASM is a very small Java library that provides high performance reflection by using code generation. - Darth Medved

KryoNet is a Java library that provides a clean and simple API for efficient TCP and UDP client/server network communication using NIO. KryoNet uses the Kryo serialization library to automatically and efficiently transfer object graphs across the network. KryoNet runs on both the desktop and on Android. KryoNet is ideal for any client/server application. It is very efficient, so is especially good for games. KryoNet can also be useful for inter-process communication. - Darth Medved

Kryo is a fast and efficient object graph serialization framework for Java. The goals of the project are speed, efficiency, and an easy to use API. The project is useful any time objects need to be persisted, whether to a file, database, or over the network. Kryo is competitive with other serialization projects. See BenchmarksAndComparisons for charts and more. If you are planning to use Kryo for network communication, the KryoNet project may prove useful. - Darth Medved

This page collects some bad code that may not look so obiously bad for beginners. Beginners often struggle with the language syntax. They also have little knowledge about the standard JDK class library and how to make the best use of it. In fact I have collected all examples from everyday junior code. I have modified the original code to give it example character and such that it highlights the problems. Many of these problems can easily be detected by FindBugs, which is available as a simple Eclipse Plug-in. I strongly recommend this tool to any beginner programmer. Also pros should run it from time to time on their codebase, and review its output carefully. It an easy to use tool and I always find some bugs when I use it. - Darth Medved

OpenJFX is the open source home of JavaFX development. The goal of OpenJFX is to build the next-generation Java client toolkit. The project intends to file a JSR in the Java SE 9 timeframe and hopes to eventually be part of the JDK proper. This Project is sponsored by the Swing Group. - Darth Medved

depending on the platform it runs on. This is harmful if the data flows from one platform to another. It is considered bad practice to rely on the default platform encoding at all. Conversions should always be performed with a defined encoding. - Darth Medved

elcome to the Colt Project. Colt provides a set of Open Source Libraries for High Performance Scientific and Technical Computing in Java. Scientific and technical computing, as, for example, carried out at CERN, is characterized by demanding problem sizes and a need for high performance at reasonably small memory footprint. There is a perception by many that the Java language is unsuited for such work. However, recent trends in its evolution suggest that it may soon be a major player in performance sensitive scientific and technical computing. For example, IBM Watson's Ninja project showed that Java can indeed perform BLAS matrix computations up to 90% as fast as optimized Fortran. The Java Grande Forum Numerics Working Group provides a focal point for information on numerical computing in Java. With the performance gap steadily closing, Java has recently found increased adoption in the field. The reasons include ease of use, cross-platform nature, built-in support for... - Darth Medved

Open Source: Since its first release in 2001 JGraph has consistently been the leading Java Swing Open Source (BSD) Graph Visualization and Layout library. Layouts: JGraph comes with a complete selection of layouts to automatically position your diagrams. There is the hierarchical layout for directional graphs, such as workflow and BPM. The organic layouts position for diagrams like computer networks, mapping overlays and UML diagrams. The tree layout is the classic layout for organizational charts. Professional Open Source: Unlike other open source projects, we won't die away. JGraph has been actively developed for every year it has existed. That's new features and examples every year, fast bug fixes and complete documentation. - Darth Medved

JUNG — the Java Universal Network/Graph Framework--is a software library that provides a common and extendible language for the modeling, analysis, and visualization of data that can be represented as a graph or network. It is written in Java, which allows JUNG-based applications to make use of the extensive built-in capabilities of the Java API, as well as those of other existing third-party Java libraries. The JUNG architecture is designed to support a variety of representations of entities and their relations, such as directed and undirected graphs, multi-modal graphs, graphs with parallel edges, and hypergraphs. It provides a mechanism for annotating graphs, entities, and relations with metadata. This facilitates the creation of analytic tools for complex data sets that can examine the relations between entities as well as the metadata attached to each entity and relation. The current distribution of JUNG includes implementations of a number of algorithms from graph theory, data... - Darth Medved
