This post is part of our ReadWriteCloud channel, which is dedicated to covering virtualization and cloud computing. The channel is sponsored by Intel and VMware . Read the case study about how Intel Xeon processors and VMware helped virtualize 12 business critical database applications . 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.

Facebook & The Semantic Web
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.
We are experiencing a big data explosion, a result not only of increasing Internet usage by people around the world, but also the connection of billions of devices to the Internet. Eight years ago, for example, there were only around 5 exabytes of data online. Just two years ago, that amount of data passed over the Internet over the course of a single month. And recent estimates put monthly Internet data flow at around 21 exabytes of data. This explosion of data - in both its size and form - causes a multitude of challenges for both people and machines. No longer is data something accessed by a small number of people.
The Age of Exabytes: Tools & Approaches for Managing Big Data
Arguably the biggest Semantic Web news of the year came in April, when Facebook announced a large-scale new platform called the Open Graph . The stated goal of the Open Graph protocol was to enable publishers to "integrate [their] Web pages into the social graph." Essentially, each web page can now become an 'object' in Facebook's social graph (which is Facebook's term for how people connect to each other in its network).

Secrets of the LinkedIn Data Scientists
I suffer from severe data envy when it comes to LinkedIn. They have detailed information on millions of people who are motivated to keep their profiles up-to-date, collect a rich network of connections and have a strong desire from their users for more tools to help them in their professional lives. Over the past couple of years Chief Scientist DJ Patil has put together an impressive team of data scientists to deliver new services based around all that information. One of my favorites is their career explorer , using the accumulated employment histories of millions of professionals to help students understand where their academic and early job choices might lead them.
People in Tech: Andraz Tori, CTO/Co-Founder of Zemanta
Zemanta is a an interesting European startup that is applying semantic technologies to blogging. Sarah Perez covered the company's launch in March. One can think of Zemanta as an auto-complete function for blogging. As you are typing up a new post, Zemanta's browser plugin fetches related content - images, articles, videos, links - and provides a simple and friendly UI for inserting the related content into your blog.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.

What Happens When You Deactivate Your Facebook Account
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.
Les compagnies aériennes, voilà un sujet d’étude plus qu’intéressant en matière de communication. Elles doivent en effet toucher un public conséquent et varié. De l’homme d’affaire au touriste « low cost », elles se doivent d’être présentes sur tous les « médias » où ces personnes sont susceptibles de rechercher de l’information et opèrent dans un secteur où la réputation et le « buzz » positif ou négatif font et défont des réputations à vitesse grand V. C’est encore plus vrai en période de crise. Il s’agit là d’informer à la fois de manière collective et individualisée, d’avoir un message « scalable » facilement relayable d’individu à individu et d’être présent partout. Y compris – et peut-être prioritairement ?

Top 10 Mobile Trends of 2010, Part 1: Design & Development
In a little under 3 weeks time, we will host our second unconference: the ReadWriteWeb Mobile Summit . It's a 1-day event at the lovely Computer History Museum, in Mountain View, California. In preparation for the RWW Mobile Summit, we're going to outline the 10 leading trends of the Mobile Web in a 3-part series of posts. We'll delve more into these trends with you at the Summit, because our unconferences are all about audience participation. In this, the first post, we'll outline 3 important design and development issues for the Mobile Web.
“Le ministère de la communication a bloqué l’importation des iPads en Israël, et les autorités douanières ont reçu la consigne des les confisquer”, écrit Bar Ben Ari et Zohar Blumenkrantz. De toutes évidences, l’interdiction est plus le résultat d’un imbroglio administratif qu’une décision technique raisonnée. Les conseillers techniques du ministère des communications on apparemment refusé l’agrément de l’appareil du fait que le Wifi de l’iPad n’obéit pas aux standards israéliens, qui sont similaires aux standards européens. Quoi qu’il en soit, l’ordre de bannir les iPads a été donné sans l’approbation du ministre des communications Moshe Kahlon. “Le responsable des douanes de l’aéroport Ben Gourion a déclaré hier qu’il avait confisqué 10 iPads, y compris ceux qui avaient été déclarés en douane par leurs propriétaires” rapporte Haaretz. Les propriétaires sont qui plus est redevable d’une amende pour chaque jour où leur appareil est retenu en douane.
