												From the Desk to the Palm
3 From the Desk to the Palm Interviews with John Ellenby, Jeff Hawkins, Bert Keely, Rob Haitani, and Dennis Boyle In the 1990s there will be millions of personal computers. They will be the size of notebooks today, have high-resolution flat-screen reflexive displays, weigh less than ten pounds, have ten to twenty times the computing and storage capacity of an Alto. Let’s call them Dynabooks. Alan Kay, 19711 Designing the laptop and the palmtop was about shrinking the computer so that you could take it with you, first as a luggable suitcase, then in your briefcase, and eventually in your pocket.The • Desktop workstation from Metaphor transition from desktop machines to laptops was about designing Computers, designed by Mike Nuttall of the physical interface to be small enough to carry easily without Matrix Product Design and Jim Yurchenco of changing the interactions on the display significantly because of David Kelley Design the smaller size. And the same interface and applications had to Photo work on both. Rick English Alan Kay is well known for his summarizing the Xerox PARC credo as: “The best way to predict the future is to invent it!” His conceptual contributions helped in the formation of the Alto and the Dynabooks in parallel, so we look first at how his ideas about portability emerged, and how his group at PARC developed the first luggable computer, the NoteTaker. The next dramatic shrinking of the machine was the leap from luggable to laptop.The author’s personal account of the story of designing the GRiD Compass, the first laptop computer, is included in the introduction, as it triggered his quest for interaction design.The rest of the story of how the Compass came into being is told in an interview with John Ellenby, the founder of GRiD Systems. -

A laptop integrates most of the typical components of a desktop computer, including a display, a keyboard, a pointing device (a touchpad, also known as a track pad, and/or a pointing stick) and speakers into a single unit. A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery. Portable computers, originally monochrome CRT-based and developed into the modern laptops, and were originally considered to be a small niche market, mostly for specialized field applications such as the military, accountants and sales representatives. As portable computers became smaller, lighter, cheaper, more powerful and as screens became larger and of better quality, laptops became very widely used for all sorts of purposes. History: As the personal computer became feasible in the early 1970s, the idea of a portable personal computer followed. A "personal, portable information manipulator" was imagined by Alan Kay at Xerox PARC in 1968, and described in his 1972 paper as the "Dynabook". -

The goal is to allow users to quickly and efficiently pull data from the MediaWiki site of their choice instead of worrying about dealing directly with the API. As such, it does not force the use of a particular MediaWiki site. It defaults to Wikipedia but other MediaWiki sites can also be used. MediaWiki wraps the MediaWiki API so you can focus on leveraging your favorite MediaWiki site’s data, not getting it. Please check out the code on github! Note: this library was designed for ease of use and simplicity. If you plan on doing serious scraping, automated requests, or editing, please look into Pywikibot which has a larger API, advanced rate limiting, and other features so we may be considerate of the MediaWiki infrastructure. Pywikibot has also other extra features such as support for Wikibase (that runs Wikidata).

==== ==== Top 13.3 Laptops Reviews www.top-13-3-laptops.blogspot.com ==== ==== A laptop computer or simply laptop (also notebook computer or notebook) is a small mobile personal computer, usually weighing from one to three kilograms, depending on size, materials and other factors.While the terms "laptop" and "notebook" are often used interchangeably, "laptop" is the older term, introduced in 1983 with the Gavilan SC. "Notebook computer" is a later coinage, which was used to differentiate smaller devices such as those of the Compaq LTE series in 1989, which were, in contrast to previous laptops, the approximate size of an A4 paper sheet.[1] Either term is often used improperly: due to heat and other issues, many laptops are inappropriate for use on one's lap, and most are not the size of an A4 sheet. Although, some older portable computers, such as the Macintosh Portable and certain Zenith TurbosPort models, were sometimes described as "laptops", their size and weight were too great for this category. Laptops usually run on a single battery or from an external AC/DC adapter which can charge the battery while also supplying power to the computer itself. An Acer laptop with touchpadAs personal computers, laptops are capable of the same tasks as a desktop PC, although they are typically less powerful for the same price. They contain components that are similar to their desktop counterparts and perform the same functions, but are miniaturized and optimized for mobile use and efficient power consumption. Laptops usually have liquid crystal displays and most of them use different memory modules for their RAM (for instance, SO-DIMM in lieu of the larger DIMMs). - 
												
												A Brand Preference of Laptop Computer in Kalayarkoil Town
Vol. 2 No. 4 September 2014 ISSN: 2319-961X A BRAND PREFERENCE OF LAPTOP COMPUTER IN KALAYARKOIL TOWN R. Mayamurugan Lecturer, Dept of Economics, Alagappa University, Evening College, Thondi, Ramnad Abstract Computer is an amazing machine. People are living in the computer age today and most of our day to day activities cannot be accomplished without using computers. Sometimes knowingly or unknowingly we use computers, people to withdraw money from ATM, publish a newsletter, drive a motorbike, design a building or new dress, or to purchase some grocery things or tyres for our car all involve computer in one way or the other. When people are breathing in the computer age and gradually computer has become such a dire necessity of life that it is difficult to imagine life without it. Computer is affecting every sphere of our life. It affected government, business, education, legal practice, entertainment, defense or home – computer has become an indispensable and multipurpose tool. Supercomputers can forecast weather, embedded computers make smart devices like washing machine that beep when washing is completed or the automobiles that give you warning before breaking down. Keywords: home – computer, Supercomputers, Dyna book, The IBM SCAMP project, PALM processor, CPU machines, SCAM prototype Definition – Precisely, “Computer is an electronic device for performing arithmetic and logical operations”, or “computer is a device or flexible machine to process data and convert it into information”. History of Laptops As the personal computer became feasible in the early 1970s, the idea of a portable personal computer followed. A “personal, portable information manipulator” was imagined by Alan Kay at Xerox PARC in 1968 and described in his 1972 paper as the “Dyna book”. -
