Peer-to-peer

Peer-to-peer
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. 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] While P2P systems had previously been used in many application domains,[3] the concept was popularized by file sharing systems such as the music-sharing application Napster (originally released in 1999).

Welcome — 8th International Conference on Peer-to-Peer Computing (P2P'08) Projects - Australian Renewable Energy Agency A world-leading prototype of a virtual power plant (VPP) will be created by installing and connecting a large number of solar battery storage systems across 1000 residential and business premises in Adelaide, South Australia, to be managed by a cloud-based Sunverge control system. The batteries will be able to ‘talk’ to each other through a cloud-based platform using smart controls, forming a connected system that will be able to operate as a 5 MW solar power plant. Need The South Australian electricity market is experiencing a number of complex, interrelated challenges with large, synchronous power generators retiring from the market, gas-fired electricity becoming more expensive through rising gas prices, and intermittent, renewable generation comprising a larger share of the energy supply mix.

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, Amazon.com 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. Normally, a processing unit is built out of a POJO (Plain Old Java Object) container, such as that provided by the Spring Framework.Virtual Middleware — a common runtime and clustering model, used across the entire middleware stack.

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. Education Information security analysts usually need at least a bachelor’s degree in computer science, programming, or a related field. Employers of information security analysts sometimes prefer applicants who have a Master of Business Administration (MBA) in information systems. Computer network architects usually need at least a bachelor’s degree in computer science, information systems, engineering, or a related field. Educational requirements for web developers vary with the setting they work in and the type of work they do. Work Experience Important Qualities

Magnetic South: Exploring a future for Christchurch together National Electricity Market 'not in the best of health': Energy Security Board The nation's top energy body has called on federal, state and territory governments to push through the National Energy Guarantee to fix the National Electricity Market, saying high electricity prices for business and households were unsustainable. In its first report on the health of the NEM, the Energy Security Board, created after the landmark Finkel Review, said the decade of inaction on climate policy to bring down Australia's carbon emissions had to end, saying politicians had to deliver the NEG early next year. "The policy uncertainty of the last decade has not only delivered insufficient electricity sector emissions reductions, but it has also increased costs in the industry," the new report released on Wednesday said. "This has led to less than optimal outcomes. The report by the ESB - chaired by respected businesswoman Kerry Schott - also took aim at the key energy bodies running the NEM saying current governance of the energy network was playing "catch-up".

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.

AEMO looks forward. Where does AEMC look? Whoever was responsible for picking Audrey Zibelman to be CEO of the Australian Energy Market Operator has probably done more to improve the outlook for decarbonised electricity supply at an efficient price in Australia than just about anyone else. Leadership matters. The AEMO started 2017 facing black marks for its role in the 2016 South Australian blackout and for seeming to have no idea about what to do to improve the electricity reliability and price outlook. The AEMO at that time seemed to walk hand in hand with the Australian Energy Market Commission, which sets the rules of the market that AEMO operates. This was despite the off and sometimes on the record complaints about the perception that the AEMC acted as a wet blanket on reform. The delayed introduction of the five minute settlement is an obvious example. Just a year on, the AEMO goes into 2018 having worked hard to prepare the NEM for the coming Summer and with the first foundations of “the plan” becoming visible.

Multitier architecture In software engineering, multi-tier architecture (often referred to as n-tier architecture) is a client–server architecture in which presentation, application processing, and data management functions are physically separated. The most widespread use of multi-tier architecture is the three-tier architecture. N-tier application architecture provides a model by which developers can create flexible and reusable applications. By segregating an application into tiers, developers acquire the option of modifying or adding a specific layer, instead of reworking the entire application. While the concepts of layer and tier are often used interchangeably, one fairly common point of view is that there is indeed a difference. Three-tier architecture[edit] Visual overview of a Three-tiered application The three-tier model is a software architecture pattern. Three-tier architecture: Presentation tier This is the topmost level of the application. Application tier (business logic, logic tier, or middle tier)

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. They're also catching on for business and technical audiences -- for example, HR departments can distribute employee manuals digitally, while IT staffers can carry around 800-page reference manuals for their favorite programming languages or operating systems without having to dislocate a shoulder. One of the most attractive features about this process is that you don't have to be a professional publisher to produce a useful and well-formatted e-book. Applications such as Calibre help you convert your document to a variety of e-book formats. But you need more than just your document. E-book creation tips Start with the cleanest possible input document.

Tesla big battery shows off its flexibility in final testing In the final days of testing before the big opening on Friday, the Tesla big battery in South Australia has been showing some of the capabilities that make it such an exciting addition to Australia’s main electricity grid. As this graph above shows, Tesla and the battery’s owner Neoen followed up the testing of its charging and discharging abilities with a display of rapid changes on Wednesday evening to underline the flexibility of the 100MW/129MWh plant. The graph charts the operations of what is known to the market as the Hornsdale Power Reserve (it is located next to Neoen’s Hornsdale wind farm). Presumably, the aim will be to take advantage of quick changes in wholesale prices, or simply to charge up when prices are low and discharge when they are high, and to help meet peak demand (which it did later Thursday, see update below). The battery is also contracted by the government to provide fast-response stability services to the grid.
