An Introduction to ADC and DAC - 0 views

  •  
    The natural state of audio and video signals is analog. When digital technology was not yet around, they are recorded or played back in analog devices like vinyl discs and cassette tapes. The storage capacity of these devices is limited and doing multiple runs of re-recording and editing produced poor signal quality. Developments in digital technology like the CD, DVD, Blu-ray, flash devices and other memory devices addressed these problems.

Micro Persuasion: The Promise and Peril of Ubiquitous Community - 0 views

  • "Steve, what's the next hot online community?" It seems as though everybody is on the lookout for the successor to MySpace, Twitter or Facebook. Nobody, even in a difficult economic climate, wants to be viewed as a latecomer. Perhaps as a defense mechanism to avoid being wrong myself, I now give a boilerplate answer that I believe can last. In short, the next big community is not a single destination. Rather, it is going to be everywhere. To paraphrase Forrester analyst Charlene Li, social networking is becoming "like air."
  • The problem, however, is that this model can't scale. Tastes change and people are always migrating to trendier sites-especially as their friends do. As a result, the Internet amber is littered with fossilized communities that once dominated. These former stalwarts include AOL, Angelfire, TheGlobe.com, GeoCities and Tripod.
  • Community today is a different animal. People now expect it to be part of virtually every online experience. Most media companies now allow users to leave comments or even create profiles. Hundreds of thousands of brands, NGOs and individuals have set up their own social networks on Ning.com. The entire web is going social.

      The entire web is going social...interesting thought.

  • actually think the shift in online communities is going towards niche social sites. Sites like Myspace and Facebook are big and their user base is overwhelmingly diverse. I think the trend now is to move towards communities that are based around shared interests, especially with the proliferation of things like ning. Will the walls between these networks break down? Probably. But I think there's always going to be a desire to commune online with people who share your interests. This is actually good news for marketers because niche communities mean more targeted marketing opportunities any way.
  • A network that works well on a mobile platform--knows where I am, who within my network is near me, offers recommendations, etc. + the concept behind FriendFeed which aggregates multiple networks gets us closer to the "air" analogy. It's really not that far off. Just waiting for wi-fi networks and handheld usability to catch up.

Collective Unconscious - 0 views

      Great view about Collective Unconscious in the 2.0 world
  • “Never before have we had such amazing ways of delivering information through television, books, photographs, graphics, computers, video, multimedia, and the internet. Yet so many children are bored and have become less and less motivated to learn about and understand the world around them,”
  • Jung’s collective unconscious is the dreamtime of Homo sapiens. ‘Collective Unconscious 2.0’ is the dreamtime of late-era hypercapitalism. The energies that inform Jung’s collective unconscious are for the most part biological: instinctual drives of fear, hunger and sex (along with the drive for psychic wholeness). The energies that inform the ‘Collective Unconscious 2.0’ are more abstract, related to the movement of electronic capital and the maximization of profit to shareholders.

  • “These modules seek to penetrate, but in a passing way. A second of your attention is all they ask. Nothing is firing that rends or cuts. It’s a massage, really, if you just go with it. And why not? Some of the most talented people on the planet have devoted their lives to creating this psychic sauna, just for you.” Ersatz environments and colourful advertisements have been with us since the fifties, de Zengotita adds, but the multimedia blitz we experience now represents a whole new level of persuasion. “Saying that it’s just more of what we had before is like saying a hurricane is just more breeze.”
  • Today’s mass dream, split from the organic foundation of the world and cobbled together from shards of television shows, newspaper and magazine articles, advertisements, films, ad jingles, ringtones – the whole mad fantasy of what’s hip, what’s not, who’s in, who’s out and the international villain du jour – is the raw stuff of the ‘Collective Unconscious 2.0’.
  • Mainstream media culture currently has all the signs of full-blown psychosis. This is analogous to Jung’s shadow. Confronting the shadow is unpleasant on a personal level, but healing cannot be effected without being confronted with the truth – and as folk wisdom has it, the truth hurts. What is positive about this process is that we’re being forced to confront the very worst in the imaginal output of our great, untethered, free market economy.
  • We are, ultimately, the stories we tell each other of our past, present and future. We become what we seek. It’s up to us to rule the imagination or leave it in the hands of a select few to shape the future of the mass dream. As Buckminster Fuller once said, “You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete.”

  • "It can discover and learn millions of relations, not just one at a time. With TextRunner, there is no human in the loop: it just finds relations on its own."
  • enter, for example, "kills bacteria,"
  • insights that "chlorine kills bacteria" or "ultraviolet light kills bacteria" or "heat kills bacteria"

  • TextRunner technology handles
  • arbitrary text on any page, including blog posts, product catalogues, newspaper articles, and more
  • "this work reflects a growing trend toward the design of search tools that actively combine the pieces of information they find on the Web into a larger synthesis."
