Big Data Is Less About Size, And More About Freedom
Editor’s note: Big Data has been around for a long time between credit card transactions, phone call records and financial markets. Companies like AT&T, Visa, Bank of America, Ebay, Google, Amazon and more have massive databases they mine for competitive advantage. But lately, Big Data is finding its way to the smallest startups.
Information Visualization on the Move. A Brief and Initial Overview
As new symbionts, tablet devices are part of our life by now. We are researching on data visualization and interaction on these devices and focusing on actual and future perspectives for dataviz. Looking for mobile applications that convey information in a visual way, we found different tools for different purposes: Reference: applications that visualize data as tools for share knowledge about specific topics as well as encyclopedic information.Business: tools that allow users to visualize and control dynamics of data (mainly financial).Entertainment: applications created for show, group, share or collect information about music, sports, movies or social networks. We noticed that reference and entertainment applications are more experimental than business apps, trying to take advantage from the specific types of interaction allowed by the device. We present here a first selection of examples of these applications, grouped by the three main purposes.
Why data visualization matters
Let’s say you need to understand thousands or even millions of rows of data, and you have a short time to do it in. The data may come from your team, in which case perhaps you’re already familiar with what it’s measuring and what the results are likely to be. Or it may come from another team, or maybe several teams at once, and be completely unfamiliar. Either way, the reason you’re looking at it is that you have a decision to make, and you want to be informed by the data before making it. Something probably hangs in the balance: a customer, a product, or a profit.
Gamification
By now you’ve likely heard about gamification in business, specifically how it’s meant to engage customers and boost employee productivity. Many places are treating gamification like a magic wand, able to cure all of a company’s ills while increasing revenues. This might be overstating its effect, but gamification can still have a positive impact on a business, which is why so many organizations are jumping on the bandwagon. The big question remains: is gamification the right move for your business?
IBM Big Data and Analytics - Case Studies
Banking Automakers gain real-time insights from data generated through in-vehicle telematics to drive improvements in auto performance and driver experiences, improve safety on the road, and develop new revenue streams by monetizing data collected. Banks analyze all of the available data about customers and transactions to optimize offers and cross sell opportunities, identify and mitigate fraud, and manage cyber threats. IBM has helped banks: Consumer products companies apply advanced analytics to deliver a differentiated brand experience, develop the most effective promotions, and accurately predict product demand to reduce inventory costs and increase profitability.
Best Supercomputers Still Not Best for Big Data
This week, China reclaimed the distinction of running the world’s fastest supercomputer; it last held that first-place ranking for eight months starting in October 2010 with its Tianhe-1A machine. Its new Tianhe-2 (“Milky Way–2”) computer is putting its competition to shame, however, performing calculations about as fast as the most recent No. 2 and No. 3 machines combined, according to Jack Dongarra, one of the curators of the list of 500 most powerful supercomputers and professor of computer science at the University of Tennessee, Knoxville. Murphy chairs the executive committee of an alternative supercomputer benchmark called Graph 500.
Paul Virilio, les revers du progrès
Philosophe et urbaniste autodidacte, disciple de Deleuze et proche de Merleau-Ponty, Paul Virilio décortique depuis quarante ans la question de la vitesse et de ses effets en tous domaines. « La planète est devenue trop petite pour le progrès.» Malgré ce constat alarmiste, Paul Virilio a le regard brillant des grands curieux. Stéphane Paoli est journaliste, il a réalisé Penser la vitesse. Étudiant, il découpait et redistribuait des dépêches au sein d’une rédaction. Mais la révolution numérique a bouleversé la vitesse de traitement de l’information et imposé une nouvelle grille de lecture du monde.
7 conseils pour une campagne QR-code / Flashcode réussie
Les codes 2D se répandent de plus en plus, tant dans les publicités que dans les services urbains ou culturels, et passée la période de découverte, ils prennent progressivement, dans nos habitudes, leur place de moyen d’accès simple et efficace au web mobile . Et même si la proportion de mobinautes qui les utilisent régulièrement est encore faible, il me semblerait contre-productif de ne pas en intégrer dans n’importe quel document imprimé, publicitaire, commercial ou technique. Sous réserve, évidemment, de disposer du contenu adéquat en ligne! Ceci étant dit, comment optimiser leur usage, pour maximiser leur effet? Je vous propose une short-list de 7 bonnes pratiques qui, si elles ne garantiront jamais le succès d’une opération, permettront au moins d’en limiter les risques d’échec…

Dossiers technopédagogiques - Nightly
Un exerciseur est une collection automatisée d’exercices le plus souvent de forme « objective ». Application pédagogique déjà populaire avant l’avènement des TIC, l’exerciseur connaît une nouvelle vie à cause de la multiplication des logiciels de d’édition et de gestion d’exercices. Cependant, la facilité technique ne doit pas faire oublier les limites pédagogiques d’un exerciseur ni les précautions qu’il faut prendre pour en calibrer les différentes composantes (questions et réponses, rétroactions, indices et explications, etc.).
