Papercut NNTP Server is a news server written in 100% pure Python. It is intended to be
extensible to the point where people can develop their own plug-ins and by that integrate the NNTP protocol to their applications.

The server is compliant with most of the RFC0977 standards (when they make sense and are needed) and implements a lot of RFC1036 and RFC2980 extensions to the NNTP protocol. It was tested against Netscape News, Mozilla News and tin (under Solaris) and it works properly.

The original need for this server was to integrate my PHP related web site forums with an NNTP gateway interface, so people could list and read the messages posted to the forums on their favorite News reader.

At first it wasnt intended to support message posting, but it made sense to allow it after seeing how effective the tool was.

The concept of storage modules was created exactly for this. I would create a Python
class to handle the inner-workins of Phorum and MySQL and if I ever wanted to integrate the server with another type of software, I would just need to write a new storage module class.

Anyway, back to the technical praise. Papercut NNTP Server forking-based on UNIX platforms and should be reasonably fast (that means basically: its pretty fast, but dont try serving 1000 connection at a time).

The best thing about the application is that it is very simple to extend it.

Hydrate is a Java tool that provides for fast efficient and error-free transformation of data between three different representations: relational databases, objects in an object-oriented programming language and extended markup language (XML).
Each of these representations has its strengths and weaknesses as shown in the diagram below; but which should you use as a basis for your application design?
Hydrate relaxes some of the pressure on this decision by providing tools for moving data from one representation to another, guided by a master UML class representation of that data.
- You want to lay a domain object model view over an existing database or set of databases. Hydrate gives you the tools to design that model in UML and map your existing data to that model. Once in the object space, you can perform complex manipulations on the objects, calculate results and save information back to a relational cache for searching or reloading, as well as converting the results to XML for sending to downstream systems or transforming to a readable format for display.
- Your project involves taking various data files fed from external systems that you want to pull into an object model on your server before writing the results down to a fully relational database. You can now respond to requests from external systems by rehydrating the data from its relational form and sending it out as XML documents or transforming those documents to a readable format for display.
- You are building a data warehouse in which you have the broad specifications for the model, but want to provide for flexibility and adaptability for future unpredicted requests. Based on a core data model, Hydrate gives you the tools to create you database schema, and write information to it, but more significantly to subsequently lay a completely different object model perhaps aggregating some of the data over the top of that schema to process it in unforeseen ways.
- You need to integrate data from many different data sources in a highly performant manner. SQL permits you to read a huge data set a row at a time and perform running calculations and filtering on that data. But the performance pressures can lead to code that is highly coupled with the database and what do you do if you need to integrate data from elsewhere in order to complete your calculations? Hydrate permits you to operate in the object space and integrate information from other sources on-the-fly.
Main features:
- To integrate legacy and other data schemas over which you have little control. Map data from many different data sources into a single self-consistent in-memory model. Different parts of the same object, as well as different sub-populations of the same object type can be drawn from different data sources, different schemas and even different database architectures.
- Load, populate and connect up multiple object types from a single query. There is no limit to the number of object types that can be loaded from a single query, or to the complexity of the relationships that can be resolved between them. Objects read from a query are automatically merged into objects already in memory.
- Full control over the SQL that runs against the database (if you need it). Any SQL queries simultaneously from multiple JDBC drivers, even using database specific optimizations, as long as they returns a result set.
- Access and manipulate the same data through the rich and powerful XML toolset. Use the same meta data that describes your objects to easily read from, write to and validate any consistent XML schema. Use XML for display, data transmission or XSLT transformation. Load XML data back into objects.
- Highly optimized performance for reading and writing SQL and XML. Since native types are used and SQL chatter is non-existent, database performance is comparable with doing the mapping by hand. XML reading and writing uses SAX exclusively.

Odyssi Certificate Server is a Java-based certificate authority server.
Odyssi Certificate Authority Server is released as 100% free software under the GNU General Public License (GPL). You are free to make changes to any of its components for deployment within your own organization. This provides you the freedom to integrate the CA with your existing systems and resources.
In addition, Odyssi CA makes use of other award-winning Open Source products, such as Hibernate, Apache Tomcat, Apache Axis, and others. Open Source database products, such as MySQL and PostgreSQL, are also fully-supported, allowing you to run your entire CA infrastructure on an Open Source platform. And, because Odyssi CA is written completely in Java, it will work on any platform with a Java VM.
Enhancements:
- This release provides minimal support for submitting certificate requests and generating X.509 certificates.

Commitfilter program can be used by projects hosting source repositories and having a commit notification mailing list.
The service allows users to subscribe to only the relevant areas of the repository for which they want to get notifications.
Commitfilter has been in use for KDE for more than 2 years. It currently supports Subversion, but CVS support will be restored.
Enhancements:
- A Web frontend is now included, which is easily changed to integrate well with existing Web pages.
- The PHP code doesnt require register-globals anymore, and more configuration options are now available for better multi-project support.

Meteosat is a SuperKaramba theme that integrate latest meteosat image in the desktop.

The fetched image is processed by imagemagick (required), to obtain a "soft start border", through png opacity.

Grifcat is a simple utility which monitors a Griffin Powermate and sends state change information to the calling script. It tracks the button and wheel motion, reporting each move as it occurs and accumulating net changes in both directions.
It is convenient for script writers and those looking for an easy way to integrate the powermate into their applications via a simple coprocess. Grifcat uses libusb to access the USB in a platform independent manner.
Enhancements:
- Fixed bug preventing grifcat from outputting on systems whose stdio library detects and buffers non-terminal i/o.
- Disabled output of read timeouts unless verbose mode enabled

KrawlSite is a web crawler/spider/ offline browser/download manager application.
To integrate with Konqueror, open the file associations page in the configuration dialog, select text/html mime type and in the embedded viewers list choose KrawlSite_Part. Now when you right click on a web-page in Konqueror, in the preview in menu, youll see KrawlSite.
Selecting it embeds the component into Konqueror as in the second screen shot. The first screen shot shows the shell in which the component runs. The third component is the configuration dialog.
To use this app to download tutorials, set offline mode on, start crawling from the start of the tutorial. If the start page of the tutorial is the TOC, set crawl depth to 1 or if the start page has the TOC along with the first chapter, set crawl depth to 0. If only next & previous links are present per chapter page, set crawl depth to number of chapters.
Enhancements:
- crash free(afaik!), esp after kde 4.1 came around.
- support for html frames
- better UI
