Pubsubhubbub - Project Hosting on Google Code

Pubsubhubbub - Project Hosting on Google Code
A simple, open, server-to-server webhook-based pubsub (publish/subscribe) protocol for any web accessible resources. Parties (servers) speaking the PubSubHubbub protocol can get near-instant notifications (via webhook callbacks) when a topic (resource URL) they're interested in is updated. The protocol in a nutshell is as follows: An resource URL (a "topic") declares its Hub server(s) in its HTTP Headers, via Link: <hub url>; rel=”hub” . The hub(s) can be run by the publisher of the resource, or can be acommunity hub that anybody can use: Google's, or Superfeedr. A subscriber (a server that's interested in a topic), initially fetches the resource URL as normal. The protocol is decentralized and free. Google and Superfeedr offer a public and scalable open hub for anybody to use. See the links in the sidebar at right. Overview

AMQP The Advanced Message Queuing Protocol (AMQP) is an open standard application layer protocol for message-oriented middleware. The defining features of AMQP are message orientation, queuing, routing (including point-to-point and publish-and-subscribe), reliability and security.[1] Overview[edit] AMQP is a binary, application layer protocol, designed to efficiently support a wide variety of messaging applications and communication patterns. It provides flow controlled,[3] message-oriented communication with message-delivery guarantees such as at-most-once (where each message is delivered once or never), at-least-once (where each message is certain to be delivered, but may do so multiple times) and exactly-once (where the message will always certainly arrive and do so only once),[4] and authentication and/or encryption based on SASL and/or TLS.[5] It assumes an underlying reliable transport layer protocol such as Transmission Control Protocol (TCP).[6] History[edit]

GSoC 2010 mid-term: Graph Streaming API During this summer, six students are working on Gephi with the Google Summer of Code. They contribute to Gephi by developing new features that will be integrated in the 0.8 version, released later this year. The purpose of the Graph Streaming API project, run by André Panisson, is to build a unified framework for streaming graph objects. Gephi’s data structure and visualization engine has been built with the idea that a graph is not static and might change continuously.

More Networks in the Humanities or Did books have DNA? Fortunately, that was a question left to Matt Jockers. I thought, though, that I might post the slides I used to describe networks in general and the examples using network analysis and representation based on the literature network that Matt has produced for his research. I’m never sure about who’s in a digital humanities audience and whether they need to have the most basic aspects of a network explained.

Visualization provides one means of combating information overload, as a well-designed visual encoding can supplant cognitive calculations with simpler perceptual inferences and improve comprehension, memory, and decision making. Furthermore, visual representations may help engage more diverse audiences in the process of analytic thinking.
