* Easy to use and easily extendable API's.
* Compatible with windows and *nix (Having GTK support).
* Compatible with Mozilla Gecko 1.4 and above. Has been tested with Mozilla Gecko 1.4 and 1.6 and 1.7.7
* Supports Tabbed and Java Internal Pane browser windows.
* Support for Profile & preferences.
* Support for Persist, Find & BroswerSetup (to enable/disable plug-in, image etc.) preferences.
* Support for accessing DOM objects of rendered page.
* JRex also implements DOM HTML2 for manipulating loaded HTML Document.
* In built support for Java WebStart deployment.
* In built support for LiveConnect which helps in communication between javascript and Java.
o Can be used for communication between XUL and JVM in which JRex is running.
Note:- JRex does not require mozilla to be installed. JRex uses GRE(which is bare minimal browser engine that can be bundled as WebStart deployment). Check the WebStart Demo to get a feel of how it works."

The Bamboo DHT -- Introduction

The Bamboo DHT -- Introduction: "A distributed hash table, or DHT, is a building block for peer-to-peer applications. At the most basic level, it allows a group of distributed hosts to collectively manage a mapping from keys to data values, without any fixed hierarchy, and with very little human assistance. This building block can then be used to ease the implementation of a diverse variety of peer-to-peer applications such as file sharing services, DNS replacements, web caches, etc."

XUI: XuiWikka: "XUI (pronounced Zoo'ey) is an Open Source, Rich Internet Application (RIA) framework for building applications in Java and XML. XUI supports Swing, AWT, SWT and HTML widget sets, letting you code in XML or Java or a mix of both. XUI used the well Model-View-Controller pattern to help separate the setup of user interfaces from business logic and data handling. The framework has been developed by Xoetrope∞, who also host the XUI Zone∞ where you will find more extensive documenation.

Welcome to the XUI Wikki. This Wiki is dedicated to all things XUI, and includes documentation of features, hints, tips and anything that might be of interest to users and developers of XUI applications."

FrontPage - Lucene-hadoop Wiki: "Hadoop DFS

Hadoop's Distributed File System is designed to reliably store very large files across machines in a large cluster. It is inspired by the [WWW] Google File System. Hadoop DFS stores each file as a sequence of blocks, all blocks in a file except the last block are the same size. Blocks belonging to a file are replicated for fault tolerance. The block size and replication factor are configurable per file. Files in HDFS are 'write once' and have strictly one writer at any time."

DBSight: Full-text database search platform/engine: "Instead of weeks or even months to develop a full-text search for your data, if you know how to use DBSight, you can easily create the full-text search literally in minutes.
Feature-rich

Besides Google-like full-text search, you can have:

* Adjust Ranking by combination of relevance and fields like product price, score, comments cout, etc
* Summarized and highlighted results
* Amazon-like Results counted for each category, and sub-category
* Order results by the field you choose
* Recent searches history
* RSS feed for latest match
* Spelling check
* Pagination of the results
* Automatic results clustering
* Multi-Server mode for Server Clustering"
