A peer-to-peer (P2P) network in which interconnected nodes ("peers") share resources amongst each other without the use of a centralized administrative system Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or work loads between peers. Peers are equally privileged, equipotent participants in the application. They are said to form a peer-to-peer network of nodes. Peers make a portion of their resources, such as processing power, disk storage or network bandwidth, directly available to other network participants, without the need for central coordination by servers or stable hosts.[1] Peers are both suppliers and consumers of resources, in contrast to the traditional client-server model in which the consumption and supply of resources is divided. Historical development[edit] Therefore, a distributed messaging system that is often likened as an early peer-to-peer architecture was established: USENET. Applications[edit]

Peer Governance If peer to peer is the relational dynamic at play in distributed networks, and peer production the process whereby common use value is produced, then peer governance refers to the way peer production is managed. See also the related concept of Panarchy Vasilis Kostakis: "Peer governance is a new mode of governance and bottom-up mode of participative decision-making that is being experimented in peer projects, such as Wikipedia and FLOSS (Bauwens, 2005a, and 2005b). Thus peer governance is the way that peer production, the process in which common value is produced, is managed." "Peer governance’s main characteristics are the Equipotentiality, i.e. the fact that in a peer project all the participants have an equal ability to contribute, although that not all the participants have the same skills and abilities (Bauwens, 2005a, and 2005b); the Heterarchy as a form of community; and the Holoptism i.e. the ability for any part to know the whole (Deleuze, 1986).

Information Security Analysts, Web Developers, and Computer Network Architects Information security is a new field and many schools are still developing programs to teach the subject. Most information security analysts, web developers, and computer network architects have a bachelor’s degree in a computer-related field. Information security analysts and computer network architects usually need experience in a related occupation, and additional knowledge of web programming languages can help web developers.

Free Open Source Distributed Micro-blogging There is plenty to say about Thimbl. Find out why we're doing this and how. So Thimbl, huh? What is it? Thimbl is free, open source and distributed micro-blogging. You can be followed at your own domain. Space-based architecture The SBA model is closely related to other patterns that have been proved successful in addressing the application scalability challenge, such as shared nothing architecture (SN), used by Google, and other well-known companies. The model has also been applied by many firms in the securities industry for implementing scalable electronic securities trading applications. Components of Space-Based Architecture[edit] An application built on the principles of space-based architecture typically has the following components: Processing Unit — the unit of scalability and fail-over.

Many free P2P file sharing programs exist. Some P2P software offers a larger user base and greater numbers of files to choose from.

Using DSH (Distributed Shell) to Run Linux Commands Across Multiple Machines Systems Administrators know all too well the importance of being able to monitor and administer numerous machines in a short time, and preferably, with as little running around as possible. Whether it is a small cloud environment, or an enormous server cluster, the ability to centrally manage computers is essential. To partly accomplish this, I am going to show you how to use a nifty little tool called DSH that allows a user to run commands over multiple machines.

Representational state transfer Representational State Transfer (REST) is a software architecture style consisting of guidelines and best practices for creating scalable web services.[1][2] REST is a coordinated set of constraints applied to the design of components in a distributed hypermedia system that can lead to a more performant and maintainable architecture.[3] REST has gained widespread acceptance across the Web[citation needed] as a simpler alternative to SOAP and WSDL-based Web services. RESTful systems typically, but not always, communicate over the Hypertext Transfer Protocol with the same HTTP verbs (GET, POST, PUT, DELETE, etc.) used by web browsers to retrieve web pages and send data to remote servers.[3] The REST architectural style was developed by W3C Technical Architecture Group (TAG) in parallel with HTTP 1.1, based on the existing design of HTTP 1.0.[4] The World Wide Web represents the largest implementation of a system conforming to the REST architectural style.

Category:Science Science needs to learn to accommodate this qualitative realm, and learn to understand it - not quantitatively, but qualitatively. This requires new methods and ways of thinking for science -- not outside of a (limited) science, but within an expanded one. - Michael Mehaffy Creating an e-book: Tips on formatting and converting your document By Serdar Yegulalp April 26, 2011 11:26 AM ET Computerworld - After years of marginal acceptance, e-books have finally started to eclipse their printed-and-bound ancestors. Casual and sophisticated readers alike are growing much more accustomed to reading from a device -- an e-reader, a smartphone, a tablet or a laptop. How non-programmers can contribute to open source projects Image by I get asked a lot by people who are interested in helping out open source projects, but have absolutely no programming skills. What can they do? Well, here’s a few ideas how non-programmers can contribute to open source projects.
