How to Build an RFID Reader Last Updated on Wednesday, 30 May 2012 05:47 Let’s face it, even though there are a wide variety of RFID readers available, there are still implementations where an off-the-shelf system isn’t “close” enough to meet the requirements. So what do you do when your project requires a UHF RFID-enabled device that just doesn’t exist? You build your own. The RFID Network produced a 30 minute episode for our cable TV series titled, How to RFID Enable Anything. Step 1: Choose Your Development Path The first decision that needs to be made after you've decided to build your own reader, is your development path. Discrete Components or RFID Reader Chip or an RFID Reader Module? There are a number of critical considerations when making this decision. Step 2: Select the RFID reader module best suited for your application If you had to start from scratch, building your own RFID-enabled device would be extremely challenging. Some of the considerations include: Comparison of RFID Reader modules Not quite yet.
The Touch-Friendly Web Keeps on Growing In December 2009, mobile search engine Taptu found about 326,000 touch-optimized mobile sites on the Internet. By April 2010, this number had grown by over 35%. According to Taptu's latest report, there are now over 440,000 touch-enabled sites on the Web. The annual growth rate for touch-friendly websites is close to 230%. In comparison, Apple's App Store is currently seeing annual growth rates of around 144% and the Android store is growing at around 400% annually. Growing Much Faster than Expected In the company's last report, Taptu estimated that the size of touch-friendly Web would reach half a million sites by the end of the year and about 1 million by the end of 2011. The reason for this rapid growth is surely the increasing popularity of touch-screen phones and touch-screen enabled devices like the iPad.

Literacy, Orality, and Cognition: An Overview - an essay by Mark Willis Literacy, Orality, and Cognition: An Overview an essay by Mark Willis (1994) Literacy often is discussed in contrast to opposite conditions, illiteracy and orality. While Heath (1992) emphasizes that literacy is a social condition, she notes that it is tested or measured through the private activities of individuals. Pairing literacy in conceptual frameworks with illiteracy or orality denotes that literacy is not an absolute condition; rather, it is a continuum of conditions with many gradations. "Speech makes us human and literacy makes us civilized" (Olson, 1988, p. 175). Ong (1982) distinguishes primary from secondary oral cultures. Tannen (1982) discusses the oral/literate continuum in a high-literate culture, contemporary American society. In the broadest contemporary view of orality, literacy, and cognition, the development of literacy along the oral/literate continuum marks a progressive or evolutionary shift in human thought processes.

Army analyst linked to WikiLeaks hailed as antiwar hero For antiwar campaigners from Seattle to Iceland, a new name has become a byword for anti-establishment heroism: Army Pfc. Bradley E. Manning. Manning, a 22-year-old intelligence analyst, is suspected of leaking thousands of classified documents about the Afghanistan war to the Web site WikiLeaks. The breach has elicited a furious reaction from national security officials, who say it has compromised the safety of U.S.-led forces and their Afghan allies. Yet, since his arrest in the spring, Manning has become an instant folk hero to thousands of grass-roots activists around the world, some of whom are likening the disclosure to the unauthorized release of the Pentagon Papers or the anonymous tips that helped uncover the Watergate scandal. Neither Manning nor his attorney have commented on the WikiLeaks dump -- and WikiLeaks has not identified Manning as its source. In the logs, Manning said he had seen "incredible things, awful things" in classified government files.
