Get Smarter - Jamais Cascio - The Atlantic - 0 views

  •  
    Pandemics. Global warming. Food shortages. No more fossil fuels. What are humans to do? The same thing the species has done before: evolve to meet the challenge. But this time we don’t have to rely on natural evolution to make us smart enough to survive. We can do it ourselves, right now, by harnessing technology and pharmacology to boost our intelligence. Is Google actually making us smarter?

Real-Life Decepticons: Robots Learn to Cheat | Science | WIRED - 1 views

      Funny how the author used the word innocence.  The writer used "innocence" to describe a robot.  Robots have feelings?
  • Soon the robots learned to follow the signals of others who’d gathered at the food. But there wasn’t enough space for all of them to feed, and the robots bumped and jostled for position. As before, only a few made it through the bottleneck of selection. And before long, they’d evolved to mute their signals, thus concealing their location.
  • “Evolutionary robotic systems implicitly encompass many behavioral components … thus allowing for an unbiased investigation of the factors driving signal evolution,” the researchers wrote Monday in the Proceedings of the National Academy of Sciences. “The great degree of realism provided by evolutionary robotic systems thus provides a powerful tool for studies that cannot readily be performed with real organisms.”

Your Brain While Watching Orange Is the New Black - Shape Magazine - 0 views

  • Like a perfectly addictive drug, almost every aspect of the television viewing experience grabs and holds your brain’s attention, which explains why it’s so tough to stop watching after just one (or three) episodes of Orange is the New Black.
  • Characters run or shout or shoot accompanied by sound effects and music. No two moments are quite alike. To your brain, this kind of continuously morphing sensory stimulation is pretty much impossible to ignore, explains Robert F. Potter, Ph.D., director of the Institute for Communication Research at Indiana University.
  • “Our brains are hardwired to automatically pay attention to anything that’s new in our environment, at least for a brief period of time,” he explains. And it’s not just humans; all animals evolved this way in order to spot potential threats, food sources, or reproductive opportunities, Potter says.

  • “This also explains how you can sit in front of the TV and binge for hours and hours at a time and not feel a loss of entertainment,” he says. “You brain doesn’t have much time to grow bored.”
  • 
Studies show that, by this point, most of your brain activity has shifted from the left hemisphere to the right, or from the areas involved with logical thought to those involved with emotion. There has also been a release of natural, relaxing opiates called endorphins, research indicates.
  • You’re noodle isn’t really analyzing or picking apart the data it’s receiving. It’s basically just absorbing. Potter calls this “automatic attention.” He says, “The television is just washing over you and your brain is marinating in the changes of sensory stimuli.”
  • At the same time, the content of your television show is lighting up your brain’s approach and avoid systems, Potter says. Put simply, your brain is pre-programmed for both attraction and disgust, and both grab and hold your attention in similar ways. Characters you hate keep you engaged just as much (and sometimes more) than characters you love.
  • 
Like any addictive drug, cutting off your supply triggers a sudden drop in the release of those feel-good brain chemicals, which can leave you with a sense of sadness and a lack of energy, research shows. Experiments from the 1970s found that asking people to give up TV for a month actually triggered depression and the sense that the participants had “lost a friend.”

Independent Survey Finds Advertisers and Media Companies Alike View Technology as Key D... - 0 views

  • The survey included 150 advertisers, media companies and agencies across the U.S. and Canada and was designed to explore the hypothesis that the evolving combination of data, technology and cross-device viewing would lead to holistic, platform-agnostic planning of linear television and digital video advertising
  • consumer engagement with content on a second screen will increase moderate or significantly
  • Another key finding is that while all parties agree that technology will be a differentiator, there are still multiple views on what this technology should enable and the capabilities that it should offer,”

Media Presence and Inner Presence: The Sense of Presence in Virtual Reality Technologie... - 1 views

  • Presence is widely accepted as the key concept to be considered in any research involving human interaction with Virtual Reality (VR). Since its original description, the concept of presence has developed over the past decade to be considered by many researchers as the essence of any experience in a virtual environment. The VR generating systems comprise two main parts: a technological component and a psychological experience. The different relevance given to them produced two different but coexisting visions of presence: the rationalist and the psychological/ecological points of view. The rationalist point of view considers a VR system as a collection of specific machines with the necessity of the inclusion of the concept of presence. The researchers agreeing with this approach describe the sense of presence as a function of the experience of a given medium (Media Presence). The main result of this approach is the definition of presence as the perceptual illusion of non-mediation produced by means of the disappearance of the medium from the conscious attention of the subject. At the other extreme, there is the psychological or ecological perspective (Inner Presence). Specifically, this perspective considers presence as a neuropsychological phenomenon, evolved from the interplay of our biological and cultural inheritance, whose goal is the control of the human activity. Given its key role and the rate at which new approaches to understanding and examining presence are appearing, this chapter draws together current research on presence to provide an up to date overview of the most widely accepted approaches to its understanding and measurement.

  • Pandora (which is also the name of the company) grew out of the Music Genome Project, which company founder Tim Westergren began six years ago.
  • He became fascinated with the way directors described the music they were looking for, which led to his wondering what made people enjoy certain types of music. He asked himself, "If people haven't found any music that they love since college, and artists are struggling to find an audience, is there a role for technology to help bridge the gap?"
  • Westergren started the Genome Project from the idea of creating a platform for connecting people with music that they'll love based on music they already enjoy. The project uses experts called "music analysts" to deconstruct music into its fundamental parts and capture the results into a database. Pandora has 40 professional musicians who come to the office every day and listen to one song at a time, analyzing each in anywhere from 200 to 400 dimensions. (The dimensions are somewhat different for each genre of music.)
  • ...9 more annotations...
  • Pandora chose the dimensions because they are quantitative. For instance, how breathy are the vocals? Is the music diatonic or chromatic? The music analysts are trained to be able to score songs consistently. In fact, one of the test cases is, "Could a group of 10 musicologists listen to a song and agree on one score for a particular element?"
  • vector space.
  • "What is exciting about the Music Genome Project, with respect to Pandora the radio-listening experience, is that by understanding the music on a song-by-song basis we can put together a playlist that has a much more natural ebb and flow than you might be able to do with collaborative filtering data," Conrad says.
  • "I think curator is the right word," Conrad replied. "Of all the financial models that could be leveraged to make Pandora a successful business, the 'play for pay' model runs completely spiritually opposite to the founding of the company.
  • I asked what Pandora was doing to avoid being influenced by big record labels, which have been widely accused of corrupting traditional radio through payola schemes.
  • "Since we use a human analyst to analyze song by song, we've experimented with using a smaller number of elements," he continued. "We've determined that you can't create interesting playlists with only 20 attributes. But we do keep an eye on machine listening as it might provide a way to augment the manual analysis."
  • I ask myself, "What's this song doing in my Bill Evans station? This song should be in my 'Soft Jazz Guitar' station. Why can't I tell Pandora to place this tune in the appropriate station?"
  • "It's fascinating to me that you raise that particular example," Conrad said. "Because the scenario that you just described is--after we evolved the product over five months and took a lot of low-hanging fruit off the table--probably the number-one listener request.
  • Pandora creates playlists with a "matching engine," written in C and Python, for each listener station. This engine builds the low-level linkage to the "source" music (the music that listeners indicate they like) and the music that actually gets played (a mixture of what the listener explicitly indicated, mixed with music that the Pandora service believes listeners will like). The replication system is Slony.

Barcode - Wikipedia, the free encyclopedia - 0 views

  • A barcode is an optical machine-readable representation of data relating to the object to which it is attached. Originally barcodes systematically represented data by varying the widths and spacings of parallel lines, and may be referred to as linear or one-dimensional (1D). Later they evolved into rectangles, dots, hexagons and other geometric patterns in two dimensions (2D). Although 2D systems use a variety of symbols, they are generally referred to as barcodes as well. Barcodes originally were scanned by special optical scanners called barcode readers. Later, scanners and interpretive software became available on devices including desktop printers and smartphones.
  •  
    Barcodes are symbols just like any other, but they can only be read by computers! They're kind of like paintings for computers.

Will Netflix Kill TV? | PopMatters - 0 views

  • Live and weekly DVR ratings have plummeted for most broadcast programs, as many viewers can now catch their favorite shows on demand via Hulu or illegal torrents.
  • Neither of these represent the biggest problem facing TV – that would be Netflix. More specifically, it’s the streaming giant’s foray into the original programming game that should cause all couch potatoes’ skin to crawl.
  • The service is a massive hit. Netflix currently takes up one-third of all the downstream bandwidth the web can provide. The average subscriber watches 87 minutes of programming per day. While short of the 18-24-year-old live television average of 3.5 hours per day, that latter number is split across hundreds of network and cable channels. Netflix has a captive audience.
  • ...9 more annotations...
  • Netflix is like an indulgent parent – offering unlimited sweets without any responsibility on the child’s behalf. Subscribers are spoiled with the model, gratifying themselves on a whim by binging new releases without regard for any psychological implications that may take place. American culture now expects instant gratification: fast food, instant messaging, instant streaming. There is virtue in patience, a virtue Netflix disregards in the name of better serving the consumer. Unfortunately, faster service does not always equal better service.
  • When network shows are stripped of commercials and sent to Netflix, the viewing experience is somewhat hollowed. Audiences have grown more used to this with TV on DVD and the restructuring of story beats on premium cable channels, but many comedies still require room to laugh and dramas room to breathe. Binging on Netflix turns distinct three-act episodes into an elongated 13th-act behemoth.
  • Conversation becomes stunted or clandestine, which eliminates much of the buzz that builds pre-season – buzz that is necessary come June when Emmy voters fill out their ballots.
  • Television executives have a right to be both frustrated with and terrified by the advent of the Netflix model.
  • Original shows ushered in using the Netflix model, like House of Cards and Hemlock Grove, have cut out the advertisers. Netflix functions as the network, and if the company decides to evolve from simply licensing original programming to actually producing, they’ll be the studio, too. Netflix is making all the money, monopolizing our attention and making poor consumers out of its subscribers. If this model becomes the norm, the producer/advertiser relationship will be pushed to the breaking point.
  • The folks at Netflix have little to fear. House of Cards executive producer Beau Willimon, in a recent Q&A for Vulture, responded to a question regarding the Netflix model and said, “Our show simply gave people the experience they had already grown accustomed to on Netflix — viewer empowerment. People like being able to decide for themselves when, where, and in what quantities they will watch their content.”
  • We’ve seen how this user-driven, consumerist approach has transformed the music industry into a shell of its former self.
  • What is the informed television devotee to do? Netflix is not inherently evil, and at only $8 a month, the access to vast libraries of programming is an invaluable asset. The answer doesn’t lie in unsubscribing from Netflix, but rather in promoting the traditional broadcast model. By watching live, conversing with friends, coworkers and strangers on Twitter, and even purchasing overpriced merchandise from beloved shows, TV buffs everywhere can help keep the industry afloat. In the hands of the responsible, Netflix is a mighty tool for good. In the hands of the ignorant, it’s a weapon that could destroy all television.
  • But what happens once Netflix reaches the point where profiting only on its own original programming makes more sense than continuing to pay licensing fees, which will skyrocket as the studios jack up prices due to diminished on-air returns? Netflix is positioning itself as its own network, assembling a lineup of programming that will survive the inevitable scripted network TV apocalypse. And once the people lose instant access to former network favorites like How I Met Your Mother and The Office, they’ll rebel by cancelling their subscriptions, the fees will also increase as competition is defeated. But by that point the damage will be irreparable – both television and Netflix will be dismantled by the impatient viewer.
