Heureusement, les ressources ne manquent pas pour relever le défi. Piéger ou éduquer, cette alternative a enflammé la toile. Fin mars, un article intitulé « Comment j’ai pourri le web » paru sur la vie moderne, un site créé par quatre enseignants est repris par Rue 89 dans une rubrique « témoignage » sous le titre « J’ai piégé le Net pour donner une bonne leçon à mes élèves ». Tous les débats, réactions… suscités par cette publication (1) prouvent bien qu’apprendre à évaluer et à valider l’information sur Internet est devenu essentiel. 1) L’article « Troll de prof qui sabote le net pour venger l’école » paru sur le site mediacteur en reprend l’essentiel et propose toutes une série de liens pour qui veut aller plus loin.

The Internet of Things (and the myth of the “Smart” Fridge) Big Data Is As Misunderstood As Twitter Was Back In 2008. Boonsri Dickinson, Business Insider In 2008, when Howard Lindzon started StockTwits, no one knew what Twitter was. Obviously, that has changed. Now that Twitter is more of a mainstream communication channel, Lindzon has figured out the secret to getting past all the noise on Twitter. By using human curation, StockTwits can serve up relevant social media content to major players like MSN Money.

The value in big data, like the sentiment in tweets, is not yet understood, Lindzon said. "Prices and business models are being made up now because this data is so fresh and interesting and real time. Disclosure: Lindzon is an investor in Business Insider.

Bill Gates Thinks Tech Billionaires Have Their Priorities Totally Out Of Whack | Web Bloggers Blue Technology 2.0+ In a fascinating interview with Financial Times Magazine, Bill Gates took a shot at tech billionaires trying to provide internet connections in the developing world, dismissing their efforts as unimportant when compared to providing the basics like running water. “Take this malaria vaccine, [this] weird thing that I’m thinking of,” Gates told Richard Waters of FT.
“Hmm, which is more important, connectivity or malaria vaccine? If you think connectivity is the key thing, that’s great. I don’t.” It’s a not-so-thinly-veiled shot at tech giants like Google and Facebook founder and CEO Mark Zuckerberg, who wrote that “connecting the world is one of the greatest challenges of our generation” back in August. According to the World Health Organization, roughly 768 million people didn’t have access to safe drinking water in 2011.

Between October of 2012 and February of 2013, I was part of the University of California Berkeley’s tech repair window staff.

The tech window is gone now (swept away as part of a mandatory building renovation and moved to a smaller store across the street), but over the course of more than 200 repairs for the wearied and panicked tides that crashed the tech shop window, I figured that there were three incredibly common Mac problems that you can easily fix yourself or at least limit the damage.
