A shift imposed by new professional practices. Microsoft has presented Monday the new version of its office suite Office (Word, Excel, PowerPoint, Outlook ..), and seems to have understood the strategic interest of adapting it to two technological innovations: tablets and cloud computing.
“The new, modern Office provides unprecedented productivity and flexibility for both the general public and the business community,” Microsoft CEO Steve Ballmer told a conference in San Francisco.
“This is a cloud service and it will give all its possibilities with Windows 8,” added the CEO, referring to the operating system level of Microsoft that will succeed Windows 7, whose commercial release is expected in October .
Microsoft said in a statement that the new Office “has an intuitive interface designed to work optimally with a touch screen, a stylus, a mouse or a keyboard on all new Windows devices, including tablets ” .
“The new Office is integrated with social networks from the start and makes possible new scenarios for reading, note-taking, meetings and communications and will be provided to subscribers via the cloud through an updated service. permanently, ” he says.
Big Data comes on laptops with GraphChi
Researchers at Carnegie-Mellon University claim to have developed a program that allows for the analysis of large volumes of data from a simple laptop. Called GraphChi, this software exploits the large capacities of the hard drives equipping the latest laptops to turn them into a platform of “Big Data” .
A reminder: the Big Data principle is the analysis of large volumes of data, internal or external to the company, collected in a wide variety of formats. This technology is used, for example, to perform a product market study, by analyzing millions of comments published on social networks (so-called “graph computing” analysis ). In general, Big Data requires huge computing capabilities and therefore requires server farms.
Twitter analyzed in less than an hour on a Mac mini
But according to Carnegie-Mellon scientists, a recent laptop can also make big data. “PCs do not have enough RAM to do a full web scan, but they have hard drives, which can hold a lot of information,” says Carlos Guestrin, co-director of Carnegie Mellon University’s lab. where GraphChi was developed. He speaks in detail about this program in the journal Technology Review , published by the Massachusetts Institute of Technology (MIT).
According to Guestrin, a simple Mac mini running with GraphChi could analyze all the tweets posted on Twitter since 2010: in 59 minutes. The same calculation would take: “400 minutes using a conventional cluster of about 1000 computers,” says the researcher. “Tools such as GraphChi will enable many companies and start-ups to meet all their graphing needs on a single machine – it pays off, and it also drives innovation,” he says.
