Extending the Blogosphere

This is a proposal for the extension of the Blogosphere, the network of Weblogs.
Individual Blogs are connected by their users implicitly: a community emerges, because users regularly read and comment on others entries. By making this connexions explicit, a web of trust is created which functions like a reputation mechanism.

The resulting system leverages the advantages of social networks for the distribution of news. It can be implemented as a decentralised system, with a simple extension to the Blogosphere.

The system is explained in a paper and in the presentation at the Mobile Entertainment conference in Manchester.

The RSS MPN-Interest module is the first part of this extension.

JChemPaint project is an editor for 2D molecular structures.
JChemPaint is intended to be complementary to Jmol, a visualisation and analysis tool for 3D molecular structures, started by Dan Gezelter at Notre Dame University, initator of the Open Science Project. and, like JChemPaint, developed by an international team of opensource programmers.
Main features:
- JChemPaint is open source OS. It is Free Software. We believe that scientific software, especially when its development was publically funded, should be free. As the GNU people put it: "``Free software is a matter of liberty, not price. To understand the concept, you should think of free speech, not free beer. ". Everyone can participate in the development of the program. Everyone can download and change the source code, provided that he makes the changes publicly available again, according to the GNU Lesser General Public License, LGPL. This ensures that the community can take advantage of any bugfix/enhancement made to the system.
- It also ensures that a scientist, who needs a standard piece of software like a structure editor as a helper application in her new program, does not have to reinvent the wheel over and over again because all the structure editors that have been written before are now proprietory software. If there is a free structure editor, she can focus on the real science.
- JChemPaint is not complete :-). Honestly, it can still use a lot of development (see below).
- Since JChemPaint is written in Java it runs on any computing platform and operating system for which a Java Virtual Machine (of version >= 2) has been implemented (like Linux, Windows 95/98/NT, Solaris, AIX and others).
- JChemPaint is avaiblable free of charge.
- JChemPaint is translated into several languages: Dutch, French, German and Polish.
Enhancements:
- This release is a build from the latest of CDK SVN.
- It adds InChI support and a SMILES entering field with memory.
- Many bugs were fixed, and the program should be faster too.

libmsntp is a full-featured, compact, portable SNTP library. SNTP (RFC 2030) is a simplified version of NTP (RFC 1305), which allows precise synchronization of system clocks over a best-effort network.

libmsntp provides SNTP client and server functionality in a shared library with a simple API.

libmsntp is implemented as a thin layer on top of msntp, N.M. Maclarens command-line SNTP utility. msntp is compact, straightforward, and elegant, and Im indebted to Nick, and to the Cambridge High Performance Computing Facility, for providing the msntp source to the public.

Installation:

To install, type "make install". You may need to be the superuser. libmsntp installs into /usr/local by default; to install to a different location, edit the Makefile and change the PREFIX variable.

Compute Portal Project is a portal project to produce a web based front end to a compute resource, such as a cluster, using PHP, mysql, and apache.
The intent is to allow non-programmers to use complex programs through an intuitive interface.
Enhancements:
- This is the third attempt to create a working release with an install script.
- The last two releases were plagued with copy and paste errors.
- This release is strictly a bugfix release that has been tested in a production environment.
- There may still be residual problems from the 0.8.8 to 0.8.9 transition that included the first install script and moved several directory locations.
- Please give this release a try.
