  • Kodak revend ses brevets pour 525 millions de dollars
  •  
    Brevets. Promotion de l'innovation ou barrière à l'entrée pour des nouveaux acteurs sur un marché ? Ce que j'ai retenu de l'affaire Apple VS Samsung c'est que presque tous les téléphones modernes sont rectangulaires avec un grand écran. C'est carrément drôle de breveter ça.

  • or centuries, the rich and the powerful documented their existence and their status through painted portraits.
  • Self-portraits can be especially instructive. By showing the artist both as he sees his true self and as he wishes to be seen, self-portraits can at once expose and obscure, clarify and distort.
  • Today, our self-portraits are democratic and digital; they are crafted from pixels rather than paints. On social networking websites like MySpace and Facebook, our modern self-portraits feature background music, carefully manipulated photographs, stream-of-consciousness musings, and lists of our hobbies and friends.

  • A new generation of social networking websites appeared in 2002 with the launch of Friendster, whose founder,
  • Friendster was an immediate success, with millions of registered users by mid-2003.
  • MySpace, launched in 2003, quickly to surpass it.
  • Besides MySpace and Friendster, the best-known social networking site is Facebook, launched in 2004.
  • Niche social networking sites are also flourishing:
  • Other niche social networking sites connect like-minded self-improvers;

  • Social networking sites are also fertile ground for those who make it their lives’ work to get your attention—namely, spammers, marketers, and politicians.
  • . On MySpace and Facebook, for example, the process of setting up one’s online identity is relatively simple:
  • By contrast, Facebook limits what its users can do to their profiles. Besides general personal information, Facebook users have a “Wall” where people can leave them brief notes, as well as a Messages feature that functions like an in-house Facebook e-mail account. You list your friends on Facebook as well, but in general, unlike MySpace friends, which are often complete strangers (or spammers) Facebook friends tend to be part of one’s offline social circle.
  • Social networking websites “connect” users with a network—literally, a computer network. But the verb to network has long been used to describe an act of intentional social connecting, especially for professionals seeking career-boosting contacts. When the word first came into circulation in the 1970s, computer networks were rare and mysterious. Back then, “network” usually referred to television. But social scientists were already using the notion of networks and nodes to map out human relations and calculate just how closely we are connected.
  • There is a Spanish proverb that warns, “Life without a friend is death without a witness.” In the world of online social networking, the warning might be simpler: “Life without hundreds of online ‘friends’ is virtual death.” On these sites, friendship is the stated raison d’être. “A place for friends,” is the slogan of MySpace. Facebook is a “social utility that connects people with friends.” Orkut describes itself as “an online community that connects people through a network of trusted friends.” Friendster’s name speaks for itself.
  • But “friendship” in these virtual spaces is thoroughly different from real-world friendship.

Opinion | The Big Myth About Teenage Anxiety - The New York Times - 0 views

      Article présentant une opinion différente de celle généralement adoptée stipulant que l'utilisation des technologies a des impacts négatifs sur les jeunes. Dans cet article, le psychiatre Richard A. Freidman présente une opinion contraire stipulant que les effets ne sont pas aussi néfastes et alarmants que le mouvement ne le laisse paraître. Note : Cet article ne présente pas mon opinion, mais vaut la peine d'être présenté et ébranle également mon opinion sur le sujet. Je trouve pertinent de le présenter.

  • I believe, is that parents have bought into the idea that digital technology — smartphones, video games and the like — are neurobiologically and psychologically toxic
  • But, once again, these studies cannot tell us whether the brain abnormalities are the result of excessive internet use, or a pre-existing risk factor for it.
  • No surprise there. If I scan your brain while showing you whatever it is that turns you on — sex, chocolate or money, say — your reward pathway will light up like a Christmas tree. But that hardly means you are addicted to these things.

      Effets long terme sur le cerveau?
  • There is a difference between an anxiety disorder and everyday anxiety.
  • Teenagers — and people of all ages — will and should feel anxious occasionally.
  • What I have noticed is that more of my young patients worry a lot about things that don’t seem so serious, and then worry about their worry.

      Serions-nous, parents, trop facilement inquiets? Plus que les générations précédentes?
  • Why, I wondered, didn’t they know this without me?
  • The myth of an epidemic of anxiety disorder rooted in a generation’s overexposure to digital technology reveals an exaggerated idea about just how open to influence our brains really are.

  • Even when we are young and impressionable, our brains have molecular and structural brakes that control the degree to which they can be rewired by experience
  • So don’t assume that there’s something wrong with your kid every time he’s anxious or upset. Our teenagers — and their brains — are up to the challenges of modern life.
