D3.js is a JavaScript library for manipulating documents based on data. D3 helps you bring data to life using HTML, SVG and CSS. D3’s emphasis on web standards gives you the full capabilities of modern browsers without tying yourself to a proprietary framework, combining powerful visualization components and a data-driven approach to DOM manipulation.

The SKOS API is a Java interface and implementation for the W3C Simple Knowledge Organisation System SKOS. For more information about SKOS see here. An implementation of the SKOS API is provided which uses the OWL 2 API, at present you will need to obtain the OWL API seperately from the OWL 2 website. [UPDATE 12-09-2011] The current release of the SKOS API has been deprecated, a new version_3 developer branch is available in the SVN repository that works with the latest OWL API v3.
For more information please contact the user group at skos-dev@googlegroups.com
The SKOS API is open source and is available under the LGPL License
The SKOS API includes the following components:
An API for the major SKOS constructs and an efficient in-memory reference implementation based on the OWL 2 API
Abstract data model for working for SKOS that avoids commitment to any of the concrete syntaxes, such as RDF
RDF/XML parser and writer
OWL/XML parser and writer
OWL Functional Syntax parser and writer
Turtle parser and writer
Support for extending the underlying SKOS data model via the OWL 2 API
Support for integration with reasoners such as Pellet and FaCT++
Range of convenience methods for working with SKOS
jsUndoable is my second attempt at a powerful, reusable, undo library for Javascript. It uses the command pattern and is roughly based on the Cocoa undo manager.
SCPSolver should enable a Java developer to use Linear Programming in less than 10 minutes.
Most solvers for linear programs are implemented in C/C++ for performance reasons. Java developers can use JNI interfaces for some solvers. However most interfaces are pretty difficult to setup, and lock the developer in to a specific solver. SCPSolver was developed to overcome those issues. The library has the following features:
easy to deploy on Linux, Mac Os X and Windows with prebuilt linear programming libraries (almost dependency-free)
plugin-concept: write model, use different solvers to solve it
currently supported solvers:
GLPK
lpsolve
CPLEX (solver pack must be built by script by user)
low learning curve: very simple, no-frills API
other features: implementation of sparse matrices and graphs, debugger for linear programs, prebuilt models for common optimization problems like set cover, ...
The Doolin framework allows the rapid development of Swing applications. It uses the Spring framework as a support for its configuration and extensibility.
Cascading is a Data Processing API, Process Planner, and Process Scheduler used for defining and executing complex, scale-free, and fault tolerant data processing workflows on an Apache Hadoop cluster. All without having to 'think' in MapReduce.
Cascading is a thin Java library and API that sits on top of Hadoop's MapReduce layer and is executed from the command line like any other Hadoop application.
As a library and API that can be driven from any JVM based language (Jython, JRuby, Groovy, Clojure, etc.), developers can create applications and frameworks that are "operationalized". That is, a single deployable Jar can be used to encapsulate a series of complex and dynamic processes all driven from the command line or a shell. Instead of using external schedulers to glue many individual applications together with XML against each individual command line interface.
The Cascading API approach dramatically simplifies development, regression and integration testing, and deployment of business critical applications on both Amazon Web Services (like Elastic MapReduce) or on dedicated hardware.
Cascading is not a new text based query syntax (like Pig) or another complex system that must be installed on a cluster and maintained (like Hive). But Cascading is both complimentary and a valid alternative to either application.
Normally smartphone events are tightly coupled to your phone device itself. When your cell phone is ringing, your phone speaker plays a ringtone. When you get a new text message, your phone displays it on its screen. Wouldn't it be thrilling to make thoses phone events visible somewhere else, on your wearable, in your living room, on your robot, in your office or where ever you want it to occur? Or would you like to use your smartphone sensors, like the accelerometer, light sensor, compass or your touchscreen to control other devices? 'android meets arduino' is a toolkit, basically consisting of an Android application and an Arduino library which will help you to interface with your phone in a new dimension. You can build your own interfaces almost without any programming experience.
Apache Shiro is a powerful and easy-to-use security framework that performs authentication, authorization, cryptography, and session management. With Shiro’s easy-to-understand API, you can quickly and easily secure any application – from the smallest mobile applications to the largest web and enterprise applications.
scalaxb-appengine is a RESTful API to run scalaxb over the web. It's implemented using n8han/Unfiltered and the full source is available on eed3si9n/scalaxb-appengine.
scalaxb-appengine came into being because I didn't know how to deploy a command line application written in Scala. Greg kindly suggested that I turn scalaxb into a web service, so I did. I guess I always thought about the possibility of making it into a web app, but this gave me a perfect opportunity to seize the moment and write a web app in Scala.
