Zoekmachine Wolfram Alpha: het intelligente zoeken? De nieuwste belofte in het land van de zoekmachines doet alles radicaal anders, zegt de uitvinder en naamgever ervan, Stephen Wolfram. Om te beginnen zoekt zijn Wolfram Alpha niet simpel in een database, maar berekent een antwoord op een zoekvraag. Hiervoor maakt het gebruik van wiskundige modellen. Huidige zoekmachines zoeken alleen naar tekstfragmenten die mogelijk relevant zijn voor de zoekvraag. De zoekvraag wordt niet echt begrepen door de software, en er is al evenmin begrip van de onderliggende structuur van de doorzochte kennis. Wolfram Alpha wordt in mei dit jaar gelanceerd Maar wat heeft een gebruiker aan de intelligente zoekmachine? Koken Wolfram Alpha is een zoekmachine die meer doet dan het toepassen van heuristiek om bij een zoekvraag de relevante pagina’s te vinden. Wie is Stephen Wolfram? Stephen Wolfram is een natuurkundige, wiskundige en handige zakenman. Rondklikken
Projectseven.com - Dreamweaver Menus, Widgets, Extensions and CS datadreamer laboratories How Google Stole Control Over Content Distribution By Stealing L There is so much misunderstanding flying around about the economics of content on the web and the role of Google in the web’s content economy that it’s making my head hurt. So let’s see if we can straighten things out. Google isn’t stealing content from newspapers and other media companies. It’s stealing their control over distribution, which has always been the engine of profits in media. Those who argue that Google is a friend to content owners because it sends them traffic overlook the basic law of supply and demand. The more content there is on the web, the less money every content creator makes, and the more money Google makes by taking a piece of that transaction. Nick Carr sums up the problem well: What Google doesn’t mention is that the billions of clicks and the millions of ad dollars are so fragmented among so many thousands of sites that no one site earns enough to have a decent online business. Google’s algorithm is based on reading “links” as votes for content.
Schizophrenic Brains Not Fooled by Optical Illusion | Wired Scie Schizophrenia sufferers aren’t fooled by an optical illusion known as the “hollow mask” that the rest of us fall for because connections between the sensory and conceptual areas of their brains might be on the fritz. In the hollow mask illusion, viewers perceive a concave face (like the back side of a hollow mask) as a normal convex face. The illusion exploits our brain’s strategy for making sense of the visual world: uniting what it actually sees — known as bottom-up processing — with what it expects to see based on prior experience — known as top-down processing. "Our top-down processing holds memories, like stock models," explains Danai Dima of Hannover Medical University, in Germany, co-author of a study in NeuroImage. "All the models in our head have a face coming out, so whenever we see a face, of course if has to come out." This powerful expectation overrides visual cues, like shadows and depth information, that indicate anything to the contrary. See Also: Image: Flickr/atöm

Ricky Gervais on the Death of Print Newspapers &#151; Big Th With rendition switcher Question: Will you mourn the death of print newspapers?Ricky Gervais: No. When’s that going to happen? I don’t think hard copies will ever be replaced, will they? I mean, I could see what you mean, because the environment or because computers; everyone will soon be online. You’re talking about the future, aren’t you? Nothing’s changed. Let’s say, you can go back, it’s like; people walk in colors, that’s it.
One Model for a New World Economy If the Industrial-Era economic system is, in fact, on its last legs, it would be useful to think through some of the possible post-capitalism models that might emerge. I don't think we have enough early indicators to create a solid vision, so anything we talk about will have to be something of a thought experiment. What kinds of constraints would we face? [Update: To clarify, as requested: this is written as a scenario set in the unspecified (but probably ~late 2020s) future, from the point of view of someone living in that future.] The trigger was a phrase we'd all become sick of: "Too Big to Fail." Traditional capitalism was, arguably, driven by the desire to increase wealth, even at the expense of other values. Resilience economics continues to uphold the elements of previous economic models that offer continued value: freedom and openness from capitalism at its best; equality and a safety net from socialism's intent. What does this all look like for everyday people? Is it perfect?
