Superorganism - Wikipedia, the free encycl A termite mound made by the cathedral termite A coral colony A superorganism is an organism consisting of many organisms. The term was originally coined James Hutton (1726-1797), the "Father of Geology" in 1789. See the discussion of Geophysiology for more on the use of this term in geological and ecological contexts. The term is now usually meant to be a social unit of eusocial animals, where division of labour is highly specialised and where individuals are not able to survive by themselves for extended periods of time. The Gaia hypothesis of James Lovelock[2] and the work of James Hutton, Vladimir Vernadsky and Guy Murchie, have suggested that the biosphere can be considered a superorganism. Superorganisms are important in cybernetics, particularly biocybernetics. Superorganic in social theory[edit] Similarly, economist Carl Menger expanded upon the evolutionary nature of much social growth, but without ever abandoning methodological individualism. Problems and criticisms[edit]

ASP.NET Hosting| ASP.NET Web Hosting| ASP Hosting| ASP Hosting Net Top 10 Server Technology Trends for the New Decade Mobility and agility are the two key concepts for the new decade of computing innovation. At the epicenter of this new enabled computing trend is cloud computing. Virtualization and its highly scaled big brother, cloud computing, will change our technology-centered lives forever. 1. Ten trends for the next 10 years. As more workers report to their virtual offices from remote locations, computer manufacturers must supply this new breed of on-the-go worker with sturdier products loaded with the ability to connect to, and use, any available type of Internet connectivity. 2. By the end of this decade, virtualization technology will touch every data center in the world. 3. Cloud computing, closely tied to virtualization and mobile computing, is the technology that industry observers view as "marketing hype" or old technology repackaged for contemporary consumption. 4. Heavy, locally installed applications will cease to exist by the end of the decade. 5. 6. 7. 8. 9. 10.

Grid Computing Info Centre (GRID Infoware) Technology, News and Reviews The Free Lunch Is Over: A Fundamental Turn By Herb Sutter The biggest sea change in software development since the OO revolution is knocking at the door, and its name is Concurrency. This article appeared in Dr. Dobb's Journal, 30(3), March 2005. Update note: The CPU trends graph last updated August 2009 to include current data and show the trend continues as predicted. Your free lunch will soon be over. The major processor manufacturers and architectures, from Intel and AMD to Sparc and PowerPC, have run out of room with most of their traditional approaches to boosting CPU performance. And that puts us at a fundamental turning point in software development, at least for the next few years and for applications targeting general-purpose desktop computers and low-end servers (which happens to account for the vast bulk of the dollar value of software sold today). Arguably, the free lunch has already been over for a year or two, only we’re just now noticing. The Free Performance Lunch The key question is: When will it end? Okay.

Windows Server 2008 and Microsoft virtualization blog How do web servers work? What happens when you enter in the address field of your browser the URL First, the browser slices the URL in 3 parts: This part indicates that the document you want to access can be retrieved from web server, which understands the HTTP protocol. The HTTP protocol is a standardized language of communication between browsers and web servers. www.aprelium.com: This is the host name of the computer from which the document can be downloaded. Then, the browser contacts a DNS (Domain Name Server) to know the IP address of the computer which full qualified domain name is www.aprelium.com. The browser establishes a connection channel with the web server on the computer which IP address was given by the DNS server and requests the document on the host which name is www.aprelium.com and which virtual path is doc/sample.html. The server decodes the request and maps the virtual path to a real one, which should match an existing file.

Grid computing The use of widely distributed computer resources to reach a common goal Grids are a form of distributed computing whereby a "super virtual computer" is composed of many networked loosely coupled computers acting together to perform large tasks. For certain applications, distributed or grid computing can be seen as a special type of parallel computing that relies on complete computers (with onboard CPUs, storage, power supplies, network interfaces, etc.) connected to a computer network (private or public) by a conventional network interface, such as Ethernet. Overview[edit] Grid computing combines computers from multiple administrative domains to reach a common goal,[3] to solve a single task, and may then disappear just as quickly. The size of a grid may vary from small—confined to a network of computer workstations within a corporation, for example—to large, public collaborations across many companies and networks. Comparison of grids and conventional supercomputers[edit] History[edit]

How can someone possibly make money from this endeavor when the vast majority of spam either gets filtered out or at the very best read and discarded by a disgruntled end user? What makes spamming profitable is huge volume. Ken Simpson and Will Whittaker, formerly developers at ActiveState, founded MailChannels to solve the spam problem. By observing spammer behavior, the MailChannels team realized that spammers are impatient. Nowadays, the majority of spam is sent from botnets--vast, distributed networks of compromised Windows PCs. While botnets are vast in size and availability, the number of machines and the sending capacity of any particular botnet is limited. Figure 1.

My Digital Life | Living Digitally and Electronically Server Types Main » Quick Reference » Posted February 10, 2011 Servers are often dedicated, meaning that they perform no other tasks besides their server tasks. This list, courtesy of ServerWatch.com, categorizes the many different types of servers used in the marketplace today. Click on the type of server you'd like to know more about, and you will be taken directly to a serverwatch.com page that provides additional information and resources. Proxy Servers A proxy server sits between a client program (typically a Web browser) and an external server (typically another server on the Web) to filter requests, improve performance, and share connections. Mail Servers Almost as ubiquitous and crucial as Web servers, mail servers move and store mail over corporate networks (via LANs and WANs) and across the Internet. Server Platforms A term often used synonymously with operating system, a platform is the underlying hardware or software for a system and is thus the engine that drives the server.
