Salvation Focus is an application that encourages a group of people to pray for others they know who do not know Jesus Christ as Lord and Saviour. Salvation Focus is a small Flash application that can be included on pretty much any Web site. There is also an administrative interface for adding people to pray for, the people that asked for prayer, and some contact info.
mod_auth_useragent2 is an Apache module that can be used to limit access to documents by means of the User-Agent. As an authentication method, this is really unsafe because it is easy to change the User-Agent in most browsers, but it could be used to prevent stupid bots and spiders from accessing your Web sites.
XMLBeans is a technology for accessing XML by binding it to Java types. XMLBeans provides several ways to get at the XML. You can do this through XML schema that has been compiled to generate Java types that represent schema types. In this way, you can access instances of the schema through JavaBeans-style accessors after the fashion of "getFoo" and "setFoo". The XMLBeans API also allows you to reflect into the XML schema itself through an XML Schema Object model. There is a cursor model through which you can traverse the full XML infoset. There is support for XML DOM.
Apache OpenNLP is a machine learning based toolkit for the processing of natural language text. It supports the most common NLP tasks, such as tokenization, sentence segmentation, part-of-speech tagging, named entity extraction, chunking, parsing, and coreference resolution. These tasks are usually required to build more advanced text processing services.
Dependency Analyzer is a utility for graphically visualizing Maven2 artifact dependency graphs. It is using Maven embedder for resolving dependencies, and based the Java Universal Network/Graph Framework (Jung) for creating and visualizing the dependency graph. The Spring rich client is used for building the GUI.
JRel is a library for the Java language that can be used to construct database queries in a programmatic fashion using a subset of the relational algebra. These queries are expressions in the form of 100% native Java code, and are translated at runtime into compliant ANSI-SQL usable with a variety of SQL databases.
Weed-FS is a simple and highly scalable distributed file system. There are two objectives: to store billions of files, and to serve the files fast! Instead of supporting full POSIX file system semantics, it implements only a key-file mapping. Instead of managing all file metadata in a central master, it manages file volumes in the central master and lets volume servers manage files and the metadata. This relieves concurrency pressure from the central master and spreads file metadata into volume servers' memories, allowing faster file access with just one disk read operation. It is modelled on Facebook's Haystack design paper. Only 40 bytes of disk storage are required for each file's metadata, and disk reads are O(1).
Creating a digital library requires converting the original scanned images into various formats. WolfpackSys is a software system that performs these large data conversion tasks in a distributed manner. The framework allows the best off-the-shelf conversion programs to be used in an automated system, and it runs the conversions in parallel on a large number of machines. It is currently used to perform image cropping, de-skewing, de-speckling, and OCR, as well as to create JPEG and Acrobat files from scanned images.
IT Mill Toolkit is a server-side RIA (Rich Internet Application) library that provides a versatile set of AJAX widgets for Java programmers. Applications are programmed in Java and executed server-side. At the client-side (i.e. in the browser), enhanced GWT widgets are used for presentation.
