Distributed economy Distributed economies (DE) is a term that was coined by Allan Johansson et al. in 2005. Definition There is no official definition for DE, but it could be described as a regional approach to promote innovation by small and medium sized enterprises, as well as sustainable development. The concept is illustrated in the figure below, that shows centralised, decentralised and distributed economies respectively. Francis Heylighen Francis Paul Heylighen (born 1960) is a Belgian cyberneticist investigating the emergence and evolution of intelligent organization. He presently works as a research professor at the Vrije Universiteit Brussel, the Dutch-speaking Free University of Brussels, where he directs the transdisciplinary research group on "Evolution, Complexity and Cognition" and the Global Brain Institute. He is best known for his work on the Principia Cybernetica Project, his model of the Internet as a Global brain, and his contributions to the theories of memetics and self-organization. Biography

Complex systems Complex systems present problems both in mathematical modelling and philosophical foundations. The study of complex systems represents a new approach to science that investigates how relationships between parts give rise to the collective behaviors of a system and how the system interacts and forms relationships with its environment. Such systems are used to model processes in computer science, biology, economics, physics, chemistry, and many other fields. It is also called complex systems theory, complexity science, study of complex systems, sciences of complexity, non-equilibrium physics, and historical physics. A variety of abstract theoretical complex systems is studied as a field of mathematics. The key problems of complex systems are difficulties with their formal modelling and simulation.
Unfluence The Unfluence site constructs maps of the funding relations between groups of candidates and donors. The data comes from candidates' required disclosures, collected and made available to the public by the National Institute on Money in State Politics (NIMSP). The basic idea is to help people understand the context of political giving, and the relative positions of various candidates in terms of who is paying for their campaign. A query is generated from the initial search settings and sent to NIMSP's API which looks in their databases and returns a list of matching candidates as an xml file. For each candidate it retrieves a list of the top contributors, and discards any with contributions below the value threshold set in the beginning. This donor-recipient information is formatted into a network and passed to GraphViz that computes positions for the nodes and draws it (with help from ImageMagik).
Self-organization Self-organization occurs in a variety of physical, chemical, biological, robotic, social and cognitive systems. Common examples include crystallization, the emergence of convection patterns in a liquid heated from below, chemical oscillators, swarming in groups of animals, and the way neural networks learn to recognize complex patterns. Overview The most robust and unambiguous examples of self-organizing systems are from the physics of non-equilibrium processes. Visualising traffic on img.ly During Nodecamp 2011, the members of 9elements - a small company dedicated to web applications - were eager to present a live tracker built with node.js. Inspired by Paul Butler's Facebook Map, the team decided to go with data from img.ly, a popular social photo sharing service that happens to be the image service of Twitterrific. The visualization they ended up creating shows the live activity of visitors on img.ly as a series of dynamic arcs across the globe.
Chaos Theory: A Brief Introduction What exactly is chaos? The name "chaos theory" comes from the fact that the systems that the theory describes are apparently disordered, but chaos theory is really about finding the underlying order in apparently random data. When was chaos first discovered? The first true experimenter in chaos was a meteorologist, named Edward Lorenz.
Vanish from the Internet With This One-Stop Website | Gadget Lab Even if you’re not Edward Snowden, there are times when excising your social media presence is necessary. Companies usually don’t make it easy, though, often hiding the delete button inside myriad confusing menus and settings. Save some time and bookmark justdelete.me, a new page that collects direct links for killing various accounts dead and puts them all on one, easy-to-use page. Justdelete.me is an excellent resource and evidently quite a bit of work went into it. Global Pulse Twitter is a remarkable tool to analyze information diffusion, and investigate social patterns and trends. In June 2011, Abdur Chowdhury and his team at Twitter posted a few visualization experiments covering the volume and worldwide scale of Twitter messages during the devastating earthquake in Japan on March 11. As they stated on the original post: "During major events, people use Twitter to share news and thoughts with friends, family and followers around the world. Messages originating in one place are quickly spread across the globe through Retweets, @replies and Direct Messages. We see this behavior during everything from sporting events like the World Cup to widely-televised news events like the royal wedding, and also in the face of major disasters like the March 11 earthquake in Japan, where the volume of Tweets sent per second spiked to more than 5,000 TPS five separate times after the quake and ensuing tsunami."
