It lets you donate your idle computer time to science projects like SETI@home, Climateprediction.net, Rosetta@home, World Community Grid, and many others.

Upon launching the application you will be prompted to choose projects to support. You will also be able to regulate the percentage of time that BOINC is allowed to compute in the application’s comprehensive options panel.

At the center of this framework is the OpenVAS Scanner which executes the actual Network Vulnerability Tests (NVTs), served with daily updates via the OpenVAS NVT Feed.

The OpenVAS Manager is the service that consolidates plain vulnerability scanning into a full vulnerability management solution. The Manager controls the Scanner via OTP and itself offers the XML-based, stateless OpenVAS Management Protocol (OMP).

All intelligence is implemented in the Manager so that it is possible to implement various lean clients that will behave consistently e.g. with regard to filtering or sorting scan results. The Manager also controls a SQL database (sqlite-based) where all configuration and scan result data is centrally stored.

For a full feature list, screenshots and download, see this section of the Open Vas website.

Watch an introduction to the Gephi:

Gephi can be applied to the following areas:

- Exploratory Data Analysis: intuition-oriented analysis by networks manipulations in real time.

- Link Analysis: revealing the underlying structures of associations between objects, in particular in scale-free networks.

- Social Network Analysis: easy creation of social data connectors to map community organizations and small-world networks.

- Biological Network analysis: representing patterns of biological data.

- Poster creation: scientific work promotion with hi-quality printable maps.

Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. Tor works with many of your existing applications, including web browsers, instant messaging clients, remote login, and other applications based on the TCP protocol.

CouchDB provides a RESTful JSON API than can be accessed from any environment that allows HTTP requests. There are myriad third-party client libraries that make this even easier from your programming language of choice. CouchDB’s built in Web administration console speaks directly to the database using HTTP requests issued from your browser.

CouchDB is written in Erlang, a robust functional programming language ideal for building concurrent distributed systems. Erlang allows for a flexible design that is easily scalable and readily extensible.

Key features include:

- Simple: Scrapy was designed with simplicity in mind, by providing the features you need without getting in your way.

- Productive- Just write the rules to extract the data from web pages and let Scrapy crawl the entire web site for you.

- Fast: Scrapy is used in production crawlers to completely scrape more than 500 retailer sites daily, all in one server.

- Extensible: Scrapy was designed with extensibility in mind and so it provides several mechanisms to plug new code without having to touch the framework core.

- Portable: Scrapy runs on Linux, Windows, Mac and BSD
Open Source and 100% Python.

- Scrapy is completely written in Python, which makes it very easy to hack.

- Well-tested: Scrapy has an extensive test suite with very good code coverage.

The community edition is based on the latest, leading edge features and bits that the Cloud.com team of engineers are working on. There are weekly builds as well as native source for developers, users and contributors to have access too.

“Ubuntu” is an ancient African word, meaning “humanity to others”. Edubuntu seeks to bring the freedoms and spirit of Ubuntu to children, parents, students, teachers, and schools.

Included with Edubuntu is the Linux Terminal Server Project, a large number of educational applications including GCompris, KDE Edutainment Suite, and Schooltool Calendar.

The first Edubuntu release coincided with the release of Ubuntu 5.10, which was codenamed Breezy Badger on 2005-10-13. Edubuntu CDs were previously available for free through their Shipit service. However, as of version 8.10, it is only available as a download.

Qimo’s interface has been designed to be intuitive and easy to use, providing large icons for all installed games, so that even the youngest users have no trouble selecting the activity they want.

Qimo is based on Xubuntu; a community maintained derivative of the Ubuntu operating system, using the Xfce desktop environment.[4][5] This helps provide low hardware requirements; minimum of 256MB of memory to run from the CD, or 192MB to install. At least 6 GB of hard drive space is recommended, and a 400 MHz or faster CPU.[2] Qimo currently uses 8.04 LTS with plans to use the next LTS Lucid Lynx.

Differences between Qimo & Edubuntu:

- Qimo was designed to be a standalone home computer for kids

- Edubuntu was designed for networked classroom computer use

- Qimo will run from a LiveCD

- From October 2008 to October 2009, Edubuntu required an existing Ubuntu installation. Edubuntu is available in a live medium, but only on a DVD, as its contents will not fit on a CD anymore.

- Qimo and Edubuntu are working to bring the Qimo games and artwork as an installable option within Edubuntu.
