Over the past decade there has been a growing public fascination with the complex "connectedness" of modern society. This connectedness is found in many incarnations: in the rapid growth of the Internet and the Web, in the ease with which global communication now takes place, and in the ability of news and information as well as epidemics and financial crises to spread around the world with surprising speed and intensity. These are phenomena that involve networks, incentives, and the aggregate behavior of groups of people; they are based on the links that connect us and the ways in which each of our decisions can have subtle consequences for the outcomes of everyone else.

Networks, Crowds, and Markets combines different scientific perspectives in its approach to understanding networks and behavior. Drawing on ideas from economics, sociology, computing and information science, and applied mathematics, it describes the emerging field of study that is growing at the interface of all these areas, addressing fundamental questions about how the social, economic, and technological worlds are connected.

The book is based on an inter-disciplinary course entitled Networks that we teach at Cornell. The book, like the course, is designed at the introductory undergraduate level with no formal prerequisites. To support deeper explorations, most of the chapters are supplemented with optional advanced sections.

Port of Basho's webmachine in scala, A REST-based system for building web applications edit

nl is a python library, that exposes a declarative API that allows us to build sentences and rules. These are used as input for a knowledge base built on the CLIPS production system. CLIPS builds a Rete network with the rules and sentences, which can then be queried for the consecuences of those in a most efficient way.

The main claim of nl is to offer a syntax that can accommodate any coherent theory that we may build with the natural language (in the same sense as something like the semantic web's OWL-Full would), while at the same time being based on a simple finite domain first order theory. This theory is NL, a discussion of which can be found here. This discussion is probably required reading to understand the breadth and the limits of nl, but not to start using it.

Myriahedral projections are a new class of methods for mapping the earth. The globe is projected on a myriahedron, a polyhedron with a very large number of faces. Next, this polyhedron is cut open and unfolded. The resulting maps have a large number of interrupts, but are (almost) conformal and conserve areas. A general approach is presented to decide where to cut the globe, followed by three different types of solution. These follow from the use of meshes based on the standard graticule, the use of recursively subdivided polyhedra and meshes derived from the geography of the earth. A number of examples are presented, including maps for tutorial purposes, optimal foldouts of Platonic solids, and a map of the coastline of the earth.

Monarch is a set of libraries and tools for creating high-performance REST-based, native JSON Web Services. Monarch is best suited for sites that rely on thousands of AJAX calls per minute to provide their core functionality. For more information on Monarch performance, check out the blog posts at Digital Bazaar.

OpenScales is a Open Source (LGPL) mapping framework based on ActionScript 3 and Flex. It has been designed for building Rich Internet Mapping Applications easily.

— a development environment for making digital art

Field is an open-source software project initiated by OpenEnded Group, for the creation of their digital artworks. It is an environment for writing code to rapidly and experimentally assemble and explore algorithmic systems. It is visual, it is hybrid, it is code-based. We think that it has something to offer a diverse range of programmers and artists.

Based on ideas started at the MIT Media Lab, Field was in development in-house for around 6 years. But for the last 16 months it has been quietly available online as an open source project. We are pleased to announce the initial "beta" binary open-source releases for Intel-based Macs OS X 10.5 or 10.6.
