World mobile data traffic to explode by factor of 26 by 2015 Anyone who thinks that the Internet revolution is in anything but its early phase had better take a look at Cisco's latest Global Mobile Data Traffic Forecast (PDF). There are so many startling predictions and observations in the report that we'll just begin with these headlines: There will be 788 million mobile-only Internet users by 2015.Global mobile data traffic will increase by a factor of 26 by 2015.World mobile data grew by a factor of 2.6 in 2010 from 2009. Average smartphone usage doubled: 79 MB per month, up from 35 MB per month in 2009.Android operating system data use is rapidly catching up to the iPhone.In 2010 almost a third of smartphone traffic was offloaded onto fixed networks via dual-mode or Femtocells.Millions of people around the world have cell phones but no electricity, and by 2015 a majority in the Middle East and Southeast Asia will live "off-grid, on-net." Three times three (almost) Double your pleasure On top of that: Android rising The second is less obvious.
Utilisation téléphone portable et Wifi, précaution à prendre Les téléphones portables et le Wifi font parti des nouvelles technologies d’information. Ces technologies sont aujourd’hui pointées du doigt par les scientifiques car leurs ondes sont soupçonnées d’être à l’origine de maux de tête, de vertiges, de malaises, voire de risque d’apparition de cancers du cerveau. En ce qui concerne les téléphones portables, les scientifiques exigent des mesures de protection plus strictes comme l’interdiction de la vente de ces appareils des enfants de moins de 12 ans. Pour les utilisateurs de portable, voici quelques conseils et précautions à prendre : En ce qui concerne le Wifi, certaines villes commencent à l’interdire dans les lieux publics comme les écoles, bibliothèque municipale… Pourquoi cette inquiétude ? Pour les utilisateurs de Wifi, voici quelques conseils et précautions à prendre :
Mobile App Usage Further Dominates Web, Spurred by Facebook Mobile App Usage Further Dominates Web, Spurred by Facebook Posted by Charles Newark-French on Mon, Jan 09, 2012 The era of mobile computing, catalyzed by Apple and Google, is driving among the largest shifts in consumer behavior over the last forty years. Powerfully, smartphones and tablets come with broadband connectivity out-of-the-box, instantly combining the best of “Silicon” and “The Cloud” for consumers. On top of this massively growing iOS and Android device installed base, roughly 40 billion applications have already been downloaded from the App Store and Android Market. The chart compares how daily interactive consumption has changed over the last 18 months between the web (both desktop and mobile web) and mobile native apps. Since conducting our first analysis in June 2011, time spent in mobile applications has grown. Our analysis shows that people are now spending less time on the traditional web than they did during the summer 2011. Facebook Pushes into Mobile Apps
Blog: Social networks in the database: using a graph database Recently Lorenzo Alberton gave a talk on Trees In The Database where he showed the most used approaches to storing trees in a relational database. Now he has moved on to an even more interesting topic with his article Graphs in the database: SQL meets social networks. Right from the beginning of his excellent article Alberton puts this technical challenge in a proper context: Graphs are ubiquitous. Social or P2P networks, thesauri, route planning systems, recommendation systems, collaborative filtering, even the World Wide Web itself is ultimately a graph! Given their importance, it’s surely worth spending some time in studying some algorithms and models to represent and work with them effectively. After a brief explanation of what a graph data structure is, the article goes on to show how graphs can be represented in a table-based database. This post is going to show how the same things can be done when using a native graph database, namely Neo4j. Representing a graph Transitive closure
Mobile Data Traffic To Increase Tenfold By 2016 - mobility Blog Mobile phone users keep downloading more data, and carriers respond by ending unlimited plans. Mobile data consumption, driven by video, has been steadily increasing since 2007 when the iPhone came out and revolutionized how people use smartphones. As speeds have increased from 2G to 3G and now to 4G, the amount of data users are consuming has continued to grow. A report by Ericsson predicts a tenfold increase in mobile data traffic in the next five years. It is a battle between the marketing department and operations. European carriers are doing what American carriers have done, which is to separate data plans from voice and text. Having fixed data plans isn't that big of a deal for most people. Many users also have multiple email accounts and apps that run in the background that consume data periodically. Why then don't carriers make this data available to users on their bill? With unlimited plans, it doesn't really matter. More Insights

Five-Year Report: It’s an App World. The Web Just Lives in It Flurry Five-Year Report: It’s an App World. The Web Just Lives in It Posted by Simon Khalaf on Wed, Apr 03, 2013 Five years ago, the iPhone ushered in the era of mobile computing. The past five years at Flurry have been wildly exciting. On the five-year anniversary of launching Flurry Analytics, we took some time to reflect on the industry and share some insights. Today, the U.S. consumer spends an average of 2 hours and 38 minutes per day on smartphones and tablets. 80% of that time (2 hours and 7 minutes) is spent inside apps and 20% (31 minutes) is spent on the mobile web. The App World Five years into its existence, the app economy is thriving, with The Wall Street Journal recently estimating annual revenue of $25 billion. In fact, not only is the installed base of devices growing, but also the number of apps consumers use. From left to right, we see that the average number of apps launched per day by consumers climbs from 7.2 in 2010 to 7.5 in 2011 and finally to 7.9 in 2012.
Gapminder: Unveiling the beauty of statistics for a fact based world view. Smartphone Shipments Surpass PCs for First Time. What's Next? With more and more consumers trading in their old feature phones for smartphones, the smartphone market actually eclipsed the PC market during the last quarter for the first time, according to data from IDC. Vendors shipped 100.9 million smartphones during the fourth quarter, according to Monday data, while IDC logged 92.1 million PC shipments during the same time period, according to IDC numbers from January. The milestone was first noted by Fortune, which said that smartphones surpassed PC shipments much faster than expected. A Morgan Stanley analyst predicted it might happen in 2012. In a Tuesday phone interview, Ramon Llamas, senior research analyst with IDC's Mobile Phone Technology and Trends team, said smartphone vs. PC shipments are a valid comparison because most people – particularly those in western countries – currently own a computer and a smartphone. As a result, we'll likely see a "ping pong effect" over the next several quarters when it comes to smartphone vs.
