Impact Factor of Computer Science Journals 2012
The Thomson Reuters Web of Knowledge has published the 2012 Journal Citation Reports. Following similar studies I performed in the past six years (2007, '08, '09, '10, '11, '12) here is my analysis of the current status and trends for the impact factor of computer science journals.
Let me start with an overview of the method I followed. I performed my analysis on the 467 journals appearing under the Web of Knowledge's computer science subject categories: artificial intelligence; cybernetics; hardware & architecture; information systems; interdisciplinary applications; software engineering; theory & methods. Note that journals may appear in many categories. In particular, there are many overlaps between the above categories and "electrical and electronic engineering" and "operations research and management science".
Don't take this report too seriously. The impact factor is notoriously prone to misuse; let's not make the situation worse. Also note that in computer science there are tens of prestigious conferences. For a ranking of these conferences you may wish to consult theConference Ranking Exercise performed by the Australian Government's, Excellence in Research for Australia body.

Raring to go. From the desktop to the cloud, Ubuntu 13.04 is ready to deploy.
Raring to go. From the desktop to the cloud, Ubuntu 13.04 is ready to deploy.
Disponible en bêta depuis le début du mois, la prochaine édition d'Ubuntu, baptisée Raring Ringtail, est disponible au téléchargement en version finale. Celle-ci apporte plusieurs nouveautés principalement portées sur l'interface Unity.
Ubuntu 13.04 disponible en version stable et en téléchargement à l'adresse
First the bad news: most of the big new features planned for Ubuntu 13.04, or Raring Ringtail, haven’t made it – they’ve been pushed back to 13.10, due in October. Despite this, the Ringtail is actually rather good.
Assuming you're a fan of the Unity interface and got past the privacy fiasco of last year - either because you’ve become comfortable with Canonical sending your desktop search queries to Amazon and others or have simply disabled the feature - Ubuntu 13.04 packs a number of new features, big and small, that make it well worth the upgrade.
