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.

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.

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.
