The igraph library for complex network research

igraph is a free software package for creating and manipulating undirected and directed graphs. It includes implementations for classic graph theory problems like minimum spanning trees and network flow, and also implements algorithms for some recent network analysis methods, like community structure search.

Snowball

Snowball is a language in which stemming algorithms can be easily represented. The Snowball compiler translates a Snowball script (a .sbl file) into either a thread-safe ANSI C program or a Java program. For ANSI C, each Snowball script produces a program file and corresponding header file (with .c and .h extensions). The language has a full manual, and the various stemming scripts act as example programs.

What Happens When Larry and Sergey Die? | The Big Money

Google, Darnton ultimately worries, cannot be trusted. Because the history of literature and publishing since the Enlightenment shows that no one, however noble, can be trusted with control of the entire corpus of human thought.

UCI Machine Learning Repository

We currently maintain 176 data sets as a service to the machine learning community. You may view all data sets through our searchable interface. Our old web site is still available, for those who prefer the old format. For a general overview of the Repository, please visit our About page. For information about citing data sets in publications, please read our citation policy. If you wish to donate a data set, please consult our donation policy. For any other questions, feel free to contact the Repository librarians. We have also set up a mirror site for the Repository.

Functional Images

There have been many libraries for generating images using functional programming, each based on its own fixed set of geometric primitives and combinators. In contrast, this chapter addresses the general notion of images, based on a very simple model: functions over continuous 2D space. Spatial transforms are mappings from 2D space to itself, and regions are just Boolean-valued images. This basis suffices for giving elegant expression to a wide range of images, as we illustrate through many examples. The library Pan embodying these ideas is freely available, and we hope to inspire others to join in the delightful search for new visual building blocks.

multiprocessing — Process-based “threading” interface — Python v2.6 documentation

multiprocessing is a package that supports spawning processes using an API similar to the threading module. The multiprocessing package offers both local and remote concurrency, effectively side-stepping the Global Interpreter Lock by using subprocesses instead of threads. Due to this, the multiprocessing module allows the programmer to fully leverage multiple processors on a given machine. It runs on both Unix and Windows.

RPyC: Unbounded Computing

RPyC (IPA:/ɑɹ paɪ siː/, pronounced like are-pie-see), or Remote Python Call, is a transparent and symmetrical python library for remote procedure calls, clustering and distributed-computing. RPyC makes use of object-proxying, a technique that employs python's dynamic nature, to overcome the physical boundaries between processes and computers, so that remote objects can be manipulated as if they were local.

CAIDA : tools : visualization : walrus

Walrus is a tool for interactively visualizing large directed graphs in three-dimensional space. It is technically possible to display graphs containing a million nodes or more, but visual clutter, occlusion, and other factors can diminish the effectiveness of Walrus as the number of nodes, or the degree of their connectivity, increases. Thus, in practice, Walrus is best suited to visualizing moderately sized graphs that are nearly trees. A graph with a few hundred thousand nodes and only a slightly greater number of links is likely to be comfortable to work with.

PARI/GP Development Headquarters

PARI/GP is a widely used computer algebra system designed for fast computations in number theory (factorizations, algebraic number theory, elliptic curves...), but also contains a large number of other useful functions to compute with mathematical entities such as matrices, polynomials, power series, algebraic numbers etc., and a lot of transcendental functions. PARI is also available as a C library to allow for faster computations.

Flare | Data Visualization for the Web

Flare is an ActionScript library for creating visualizations that run in the Adobe Flash Player. From basic charts and graphs to complex interactive graphics, the toolkit supports data management, visual encoding, animation, and interaction techniques. Even better, flare features a modular design that lets developers create customized visualization techniques without having to reinvent the wheel.
