A simple particle system physics engine for processing. I've designed this to be application / domain agnostic. All this is supposed to do is let you make particles, apply forces and calculate the positions of particles over time in real-time. Anything else you need to handle yourself.
For people who want to use QR Codes within the Flash environment, LOGOSWARE (the company I work for) has released a QR Code Reader into the Spark Project.
It is essentially a library that recognizes and decodes any QR Code from any image source.
The boilerpipe library provides algorithms to detect and remove the surplus "clutter" (boilerplate, templates) around the main textual content of a web page.
The library already provides specific strategies for common tasks (for example: news article extraction) and may also be easily extended for individual problem settings.
Extracting content is very fast (milliseconds), just needs the input document (no global or site-level information required) and is usually quite accurate.
Boilerpipe is a Java library written by Christian Kohlschütter. It is released under the Apache License 2.0.
EzDL is a tool to provide Easy Access to Digital Libraries. It is a Java based application that allows users to search several related libraries at once, presents a combined result view and offers a number of possibilities to work with and organize results. At the moment the program focuses on search for scientific literature, but other types of digital libraries and documents will be supported in the future.
