Statisticien : un métier sexy, peu stressant et qui aura la côte en 2020 - Statosphère, les statistiques du web et d'ailleurs
Le métier de statisticien serait voué à un magnifique avenir si on en croit une poignée d'articles publiés ces dernières semaines. Sergey Brin, co-fondateur de Google, en est même la preuve vivante puisque depuis sa rencontre avec Larry Page en 1995, son crédo n'a cessé d'être le data mining , c'est à dire l'analyse de données statistiques (comme en témoigne son profil publiée en 1998 sur le site de l'université de Stanford). Les travaux effectués sur le moteur de recherche constituent une preuve magistrale de cet attachement obsessionnel aux données statistiques : Google est aujourd'hui une des meilleures solutions pour tirer des informations pertinentes à partir de milliards de données. Rapides, exhaustives et faciles d'accès, les nouvelles technologies de l'information offrent des possibilités insoupçonnées jusqu'alors. Hal Varian , chef économiste depuis 2002 chez Google , va même plus loin : pour lui, " le job sexy des dix prochaines années sera celui de statisticien ".
A traditional view of data analysis involves precision, preparation, and methodical examination of defined datasets. Philipp Janert , author of " Data Analysis with Open Source Tools ," has a somewhat different perspective. Those traditional elements are still important, but Janert also thinks simplicity, experimentation, action, and natural curiosity all shape effective data work. He expands on these ideas in the following interview. Philipp Janert: I observe a tendency to do something complicated and fancy; to bring in a statistical concept and other "sophisticated" stuff. The problem is that the sophisticated stuff isn't that easy to understand.

The Joy of Stats with Hans Rosling
The Joy of Stats , a one-hour documentary, hosted by none other than the charismatic Hans Rosling, explores the growing importance of statistics: [W]ithout statistics we are cast adrift on an ocean of confusion, but armed with stats we can take control of our lives, hold our rulers to account and see the world as it really is. What's more, Hans concludes, we can now collect and analyse such huge quantities of data and at such speeds that scientific method itself seems to be changing. From the description, it sounds like they'll touch on Crimespotting by Stamen, Google Translation, among other data-driven projects. Whatever they cover, it's bound to be interesting with Rosling at the front. Below is a four-minute clip of Rosling presenting world development in the context of income versus lifespan.Humanities Scholars Embrace Digital Technology - NYTimes.com
Members of a new generation of digitally savvy humanists argue it is time to stop looking for inspiration in the next political or philosophical “ism” and start exploring how technology is changing our understanding of the liberal arts. This latest frontier is about method, they say, using powerful technologies and vast stores of digitized materials that previous humanities scholars did not have. These researchers are digitally mapping battlefields to understand what role topography played in victory, using databases of thousands of jam sessions to track how musical collaborations influenced jazz, searching through large numbers of scientific texts and books to track where concepts first appeared and how they spread, and combining animation, charts and primary documents about Thomas Jefferson’s travels to create new ways to teach history. This alliance of geeks and poets has generated exhilaration and also anxiety.
La gestion des données - l'actualité
27/03/2012 | Informatique | Informatique - Bureautique | Bureautique | Le choix de la rédaction | Cloud et Data Selon une étude de Forrester Consulting, les directeurs informatiques estiment que le cloud computing présente encore de nombreuses zones d'ombres. Ils craignent également que ce soit l'occasion pour leurs dirigeants de se passer d'eux. Plus de deux tiers des DSI européens ont peur que le Cloud Computing porte préjudice à leur activité.

The next big idea in language, history and the arts? Data.
We've all heard it: according to Hal Varian, statistics is the next sexy job . Five years ago, in What is Web 2.0 , Tim O'Reilly said that "data is the next Intel Inside." But what does that statement mean? Why do we suddenly care about statistics and about data? The web is full of "data-driven apps." Almost any e-commerce application is a data-driven application.
