Discover MySQL Web Reference Architectures & Best Practices Discover MySQL Web Reference Architectures & Best Practices

Dear Pascal Fares,

Are you looking to deploy new web, mobile and cloud applications?

Do you have concerns about scaling your infrastructure while improving user experience and maintaining both agility and security?

Success or failures of such initiatives are highly dependent on selecting the right technologies from the start, eliminating extensive trial and error potentially resulting in missed opportunities.

MySQL is deployed in 9 of the top 10 most trafficked web sites worldwide including Facebook, Twitter, Google and YouTube, and the world's most popular open source database has become the leading database in the cloud. Oracle's MySQL team has acquired unique insights into how to design database-driven web architectures, whether deployed on-premise or in the cloud, addressing the aforementioned concerns while minimizing cost and risk.
Access our Resource Kit to discover:
  • Reference Architectures based on best practices developed from working with the most successful web properties on the planet
  • How to leverage the new MySQL 5.6 features and MySQL Cluster to scale web services
  • How to unlock the value of Big Data with MySQL and Hadoop

Intel: Keeping Up With Moore's Law Is Becoming a Challenge

IDG News Service (05/08/13) Agam Shah

Intel will continue to keep pace with Moore's Law for now, but as chips continue to shrink, maintaining the pace of progress is growing more difficult, says Intel's William Holt. Intel has used Moore's Law as a baseline for decades to increase transistors and make chips smaller and more cost-effective, resulting in faster and more efficient computers. "Are we closer to an end than we were five years ago? Of course," Holt says. "But are we to the point where we can realistically predict that end, we don't think so." He notes that manufacturing is more complicated with smaller chips, which are subject to a wider class of defects as sensitivities and minor variations increase, requiring extreme attention to detail. "As we make things smaller, the effort that it takes to make them actually work is increasingly difficult," Holt says. However, he says Intel has discovered new tools and innovations to make new generations of chips possible. Meanwhile, other companies, such as IBM, are researching ways of extending Moore's Law, and the U.S. National Science Foundation is funding a research effort called Science and Engineering Beyond Moore's Law, which focuses on manufacturing, nanotechnology, multicore chips, and emerging technologies.

Google+ : déjà 359 millions d'utilisateurs actifs


Google+ croissance Facebook réseau social
Une récente étude du cabinet d'analyse GlobalWebIndex a montré que Google+ était plutôt en forme depuis quelques mois et que le nombre de comptes actifs atteint déjà 360 millions d'utilisateurs. Des chiffres à mettre en perspective par rapport à deux gros concurrents, Twitter et ses 297 millions de comptes actifs et Facebook avec ses 701 millions d'utilisateurs actifs, sur plus d'1,1 milliard de comptes. On entend par compte actif, un compte sur lequel il est constaté au moins une interaction dans le mois.

Un point qui mettrait Google en avantage statistique, puisque lorsque l'on ne va pas tweeter pendant un mois, on n'utilise pas Twitter. En revanche, lorsque l'on ne va pas sur Google +, on utilise peut-être YouTube, le Play Store, Maps, etc. qui crée des interactions avec le compte Google+, comptabilisée en tant que telles.
