The Freenet Project
[17 users on Ohloh]
Freenet is a peer-to-peer network designed to allow the distribution of information over the Internet in an efficient manner, without fear of censorship. It is completely decentralized (there is no person or computer essential to its operation), meaning that Freenet cannot be attacked like centralized peer-to-peer systems such as Napster. Freenet also employs intelligent routing and caching to learn to route requests more efficiently, automatically mirror popular data, make network flooding almo...

ScopePort
[6 users on Ohloh]
ScopePort is an easy to configure but powerful remote monitoring server. You can use it to monitor servers all over the web. It permanently checks system functions of servers and warns you if something goes wrong. It also provides a nice web interface that lets you have the overview of all your servers and their health.

The main target of ScopePort is to reliably monitor the health of your servers and giving you the ability to have a central point to organize your network. Every function o...

i2p
[3 users on Ohloh]
I2P is an anonymous network, exposing a simple layer that applications can use to anonymously and securely send messages to each other. The network itself is strictly message based (ala IP), but there is a library available to allow reliable streaming communication on top of it (ala TCP). All communication is end to end encrypted (in total there are four layers of encryption used when sending a message), and even the end points ("destinations") are cryptographic identifiers (essentially a pair o...
pymon
[3 users on Ohloh]
pymon is an open source network and process monitoring solution implemented in python. The interface and configuration is designed to be easily and rapidly deployed, saving on time and overhead often associated with other monitoring solutions.
Virtual Object System (VOS)
[2 users on Ohloh]
VOS is a library and network protocol for interlinked object structures, which can be easily distributed over networks. Notifications of changes are automatically sent to other applications/clients. VOS simplifies concurrent asynchronous programming, both within the same process or distributed over the network. Revision control (versions), access control, and other important features are built in. VOS object messaging also allows access from multiple languages.

VOS forms the basis for...

Dijjer
[1 users on Ohloh]
Dijjer is free P2P software that dramatically reduces the bandwidth needed to host large files.

A type of distributed web cache, Dijjer nodes rely on a small number of "seed" peers, through which new Dijjer peers can assimilate into the Dijjer network. These are not essential however, you can (through use of Dijjer's command line interface) instruct Dijjer to assimilate through any Dijjer peer. You could even create a network of Dijjer nodes that is entirely separate from the main Dijjer n...

Flox
[1 users on Ohloh]
A project in progress that will speed up the G2-network by using the similarity in files instead of the complete file.
Ronin
[1 users on Ohloh]
Ronin is a Ruby platform designed for information security and data exploration tasks. Ronin allows for the rapid development and distribution of code over many of the common Source-Code-Management (SCM) systems.
Spring Python
[1 users on Ohloh]
Spring Python is an offshoot of the Java-based SpringFramework and AcegiSecurityFramework, targeted for Python. Spring provides many useful features, and I wanted those same features available when working with Python.

Several key features include:
* Inversion of control
* Aspect oriented programming
* DatabaseTemplate
* Database transaction management
* Distributed remoting
* Security

You can pick an...

traktopel
[0 users on Ohloh]
A web interface for managing a network of objects.

Aimed at students (well.. me) wanting to interact with their personal stuff, when they are far from home. Used at home on a wifi touchphone, it will act like a "super" remote.

It uses the original Python's embedded HttpServer as backend to create a network of semantically defined python objects.

In the phase of early software design and redesign, but I'll add more things (and open the svn/wiki/issue tracker) here soon.

Pure-man Amazon SQS Service in Erlang. The original service is too heavy and not so fast for me. And there is still no Erlang SQS API bindings. I want also to use UBF [ http://www.sics.se/~joe/ubf/site/home.html ] for data transport format.

Tags: swe fers webservices distributed web
Your team is charged with building a prototype of Fire Emergency Response System (FERS). FERS is intended to be used by several organizations (agents) to automatically detect, respond, and manage fire emergency situations. Given that the system is going to cross the boundaries of several organizations, the architects would like to design and develop the system according to the principles of Service Oriented Architecture (SOA) and use the web services technology for its implementation. FERS consi...

meshweb
[0 users on Ohloh]
meshweb is a stand-alone web application which aims for consumer-grade visualization of a non-centralized ip-based mesh network. A localized data source is provided by the node's current routing tables. The primary purpose is to bootstrap an autonomous worldwide network by discovery of availability through radiation of initial nodes.
