Personal digital assistant A personal digital assistant (PDA), also known as a palmtop computer, or personal data assistant,[1][2][3] is a mobile device that functions as a personal information manager. PDAs are largely considered obsolete with the widespread adoption of smartphones.[4] Nearly all current PDAs have the ability to connect to the Internet. A PDA has an electronic visual display, enabling it to include a web browser, all current models also have audio capabilities enabling use as a portable media player, and also enabling most of them to be used as mobile phones. Most PDAs can access the Internet, intranets or extranets via Wi-Fi or Wireless Wide Area Networks. Most PDAs employ touchscreen technology. The first PDA was released in 1984 by Psion, the Organizer II. The term PDA was first used on January 7, 1992 by Apple Computer CEO John Sculley at the Consumer Electronics Show in Las Vegas, Nevada, referring to the Apple Newton.[7] Typical features[edit] Touch screen[edit] Memory cards[edit] [edit]

A new report from market research firm Gartner has phones running Google’s Android operating system accounting for 52.5 percent of the worldwide smartphone market in the third quarter of 2011, giving it more than three times the share of its nearest global competitor Symbian, with a 16.9 percent share. (Apple’s iOS managed a third-place finish for the quarter, with a 15 percent share.) Overall, Gartner found that nearly 60.6 million Android phones were sold to customers during the quarter, compared to about 17.3 million iPhones. With figures like that, it’s easy to jump to a conclusion that Android is winning the smartphone wars: after all, when a product’s share or sales tips over 50 percent, it’s generally viewed as a market-dominating force. But as Charlie Sheen can attest, there’s more than one definition of “winning.” Brace yourself: the colors are jarring: What matters more: market share or actually making money? The market share argument The profit argument What the graphs don’t show
Networked Politics Smartphone Sales Top Feature Phones Thanks to Samsung Smartphone sales were on the rise again during the quarter, toppling sales of feature phones for the first time, according to data from Gartner. Samsung was out in front with more than 71 million units sold, thanks to its Galaxy S 4 smartphone, up almost 30 percent from the same time period last year. Apple came in second with about 32 million iPhones sold. "Smartphones accounted for 51.8 percent of mobile phone sales in the second quarter of 2013, resulting in smartphone sales surpassing feature phone sales for the first time," Anshul Gupta, principal research analyst at Gartner, said in a statement. IDC, however, said that milestone occurred a little earlier in the year. Whenever it happened, the news is not particularly surprising. The question is, can anyone top Samsung in the smartphone race? Apple, meanwhile, saw strong iPhone sales during the quarter, but it's average selling price (ASP) took a hit due to the popularity of the iPhone 4 among new smartphone buyers.
To connect or not to connect? Dan Zack, Better! Cities & Towns Perhaps it is a natural territorial instinct to wall ourselves into a protected enclave. Much has been written about the late 20th Century phenomenon of gated developments, but that isn't the only time we block access in our neighborhoods. The lollipop cul-de-sac street patterns of many American suburbs are also meant to block; and sometimes older neighborhoods are retrofitted to block auto access, pedestrian access, or both. As a planner, I see this a lot, but I recently saw it in action in my own neighborhood. Our Parks and Recreation Department held a couple of neighborhood meetings to work on a new design for the reconstruction of this park. Why We Block Why is this done? • Fear of Traffic. • Fear of On-Street Parking Jams. • Fear of Crime. The Problem With Blocking While I understand these fears, disconnectedness is not the answer. • Dangerous Dead Ends. • No Eyes on the Street. • Slower Emergency Response Time. • More traffic fatalities.

Functional contextualism Functional contextualism is a modern philosophy of science rooted in philosophical pragmatism and contextualism. It is most actively developed in behavioral science in general and the field of behavior analysis in particular. Functional contextualism serves as the basis of a theory of language known as relational frame theory[1] and its most prominent application, acceptance and commitment therapy.[2] It can be viewed as an extension and contextualistic interpretation of B.F. Skinner's radical behaviorism, and emphasizes the importance of predicting and influencing psychological events (including thoughts, feelings, and behaviors) by focusing on manipulable variables in their context. Contextualism[edit] The form of contextualism from which functional contextualism emerged is the one described by the philosopher Stephen C. The root metaphor of contextualism is the "act in context," whereby any event is interpreted as an ongoing act inseparable from its current and historical context.
Page 2 - The history of digital photography - Slideshow Believe it or not, non-chemical cameras have only existed for 30 years — and true digital cameras that store files as JPEGs and MPEGs have been around for just 20 years. After last week’s Lytro announcement, we found ourselves thinking about the major advances and innovations that have shaped digital photography. It’s been a crazy ride, after all! Without further ado, the very first commercial, electronic camera: the Sony Mavica. Situated cognition Situated cognition is a theory that posits that knowing is inseparable from doing[1] by arguing that all knowledge is situated in activity bound to social, cultural and physical contexts.[2] Under this assumption, which requires an epistemological shift from empiricism, situativity theorists suggest a model of knowledge and learning that requires thinking on the fly rather than the storage and retrieval of conceptual knowledge. In essence, cognition cannot be separated from the context. History[edit] While situated cognition gained recognition in the field of educational psychology in the late twentieth century,[3] it shares many principles with older fields such as critical theory, (Frankfurt School, 1930; Freire, 1968) anthropology (Jean Lave & Wenger, 1991), philosophy (Martin Heidegger, 1968), critical discourse analysis (Fairclough, 1989), and sociolinguistics theories (Bhaktin, 1981) that rejected the notion of truly objective knowledge and the principles of Kantian empiricism.

Portable media player A mobile digital media player (M-DMP), portable media player (PMP), or digital audio player (DAP), is a portable digital consumer electronics device capable of storing and playing digital media such as audio, images, and video files.[1][2] The data is typically stored on a flash memory, microdrive, or hard drive. In contrast, analog portable audio players play music from non-digital media such as cassette tapes, or records. Often mobile digital audio players are marketed and sold as "portable MP3 players", even if they also support other file formats and media types.[3][4] Other types of electronic devices which can also act as a like mobile digital media player, but only have those media playback features as a secondary function, are cellphones, internet tablets, and sometimes even digital cameras are referred as portable media players because of their playback capabilities.[5] This article focuses on portable devices that have the main function of playing media.

Il Web 3.0 è un termine a cui corrispondono significati diversi volti a descrivere l'evoluzione dell'utilizzo del Web e l'interazione fra gli innumerevoli percorsi evolutivi possibili. Questi includono: Storia[modifica | modifica sorgente] Il termine Web 3.0 è apparso per la prima volta agli inizi del 2006 in un articolo di Jeffrey Zeldman critico verso il Web 2.0 e le sue tecnologie associate come AJAX. Nel maggio 2006, Tim Berners-Lee[1] affermava: Durante il Technet Summit nel novembre 2006, Jerry Yang, fondatore e presidente di Yahoo! Allo stesso Technet Summit, Reed Hastings, fondatore e CEO di Netflix, riassumeva in una semplice formula la definizione delle diverse fasi del web: Il termine Web 3.0 è diventata una materia di crescente interesse e dibattito a partire dalla fine del 2006 sino a 2007.
