Adrian Cockcroft , a cloud architect at Netflix , is running a series of posts looking at how different NoSQL databases handle common cloud computing tasks. All the usual disclaimers apply: SQL is good for some things, and different scenarios call for different NoSQL solutions. No one solution is necessarily "better" overall. However, as Cockcroft writes "We need a basis for comparison across them, so that we understand the differences in behavior."
This week we've been exploring the emergence of the Semantic Web among companies like Best Buy and Google . It's all thanks to RDFa , code that is inserted into the HTML of web pages to add extra meaning. The increasing usage of RDFa was one of the main themes at the recent Semantic Technology conference in San Francisco. There is perhaps no better example than Facebook 's use of RDFa. We chatted to Facebook open standards evangelist David Recordon to find out more.
Internetome , the U.K.'s first full day conference dedicated to the Internet of Things was held on Nov 10 in London. In front of a full attendance, with representatives from academia, government, and enterprise, a wide range of speakers illustrated the promise and the challenges of the complex systems based on smart sensor networks. The Economist magazine featured in its current issue a special report on Smart Systems, underlining how rich, and important these ICT solutions have become, and how they will in the future sustain value added services for a wide set of vertical application areas. Guest author David Orban is the Chairman of Humanity+ , an organization dedicated to promoting understanding, interest, and participation in fields of emerging innovation.
Yesterday we wrote about the increasing usage of Semantic Web technologies by large commercial companies like Facebook, Google and Best Buy. The Semantic Web is a Web of added meaning, which ultimately enables smarter and more personalized web apps to be built. In this post we explore how a leading U.S. retailer, Best Buy , is using a Semantic Web markup language called RDFa to add semantics to its webpages. This is not just an academic exercise for Best Buy. As we will see, semantic technology has already led to increased traffic and better service to its customers.
In an hour long interview posted today about the Semantic Web, W3C Director Tim Berners-Lee says all the pieces are in place to move full steam ahead and realize the potential of a world of structured, machine readable data. Available as a part of the Talking with Talis semantic web podcast series, the interview ( listen here ) is summarized on interviewer Paul Miller's new ZDNet blog dedicated to the semantic web. A full transcript is available here . It's an important conversation and a good introduction to what the semantic web is. Also notable is the way that Berners-Lee sees Semantics and Data Portability as very related.
In May last year we wrote about the state of Linked Data , an official W3C project that aims to connect separate data sets on the Web. Linked Data is a subset of the wider Semantic Web movement, in which data on the Web is encoded with meaning using technologies such as RDF and OWL. The ultimate vision is that the Web will become much more structured, which opens up many possibilities for "smarter" Web applications. At this stage last year, we noted that Linked Data was ramping up fast - evidenced by the increasing number of data sets on the Web as at March 2009. Fast forward a year and the Linked Data "cloud" has continued to expand.
Facebook is a big part of millions and millions of peoples' lives, but what happens when you pull the plug? Last night I met a man who walked to the edge of the cliff and nearly deactivated his Facebook account. He took a screenshot of what he saw after clicking the "deactivate my account" link on his account page - and it is pretty far-out. That man considered quitting Facebook because it was having an adverse emotional impact on him and I'll spare him and his contacts from posting the screenshot he shared with me. I have posted below though a shot of the screen I saw when I clicked that button myself. Check it out.
