    but so far only an announcement ... they want to be ready in autumn only ... :-(
  •  
    yes, but already 172000 dollars of donation (!!) and plenty of guys offered their service for the coding ! this is something a lot of people is waiting for !

Google defends H.264 removal from Chrome, says WebM plug-ins coming to Safari and IE9 -- Engadget - 1 views

  •  
    Free software or a marketing move?
  •  
    They have all the weight they need to pull this through. I'm dreaming of a day in which they will switch all Youtube videos to WebM, with all the Apple devices becoming useless to watch Internet video :) And Steve Jobs struggling to explain why, after wearing the mantle of open standards in the whole Flash vs HTML5 thing, he's now pushing H.264 against WebM... Anyway, in my view the less encumbered formats around the best for everyone's freedom.

    And what does one win in the end? Yet another unfeasible concept to be archived somewhere in a journal? Look at "Millis hypothetical drives"... Give me a break, for sure!!
  •  
    I like the sentence "16 peer-reviewed journal articles, and an award-winning website (Warp-When), all for a total investment of less than $1.6M". This gives 100.000 dollars per peer-reviewed paper (we neglect the award-winning web-site under the assumption that is the easy part....). With these number the ACT in 2010 cashed 1.4 millions only in research papers making it an obvious good investment for the European Space Agency also in austerity times!!!

Bitcoin P2P Currency: The Most Dangerous Project We've Ever Seen - 10 views

  • After month of research and discovery, we’ve learned the following:1. Bitcoin is a technologically sound project.2. Bitcoin is unstoppable without end-user prosecution.3. Bitcoin is the most dangerous open-source project ever created.4. Bitcoin may be the most dangerous technological project since the internet itself.5. Bitcoin is a political statement by technotarians (technological libertarians).*6. Bitcoins will change the world unless governments ban them with harsh penalties.
  • The benefits of a currency like this:a) Your coins can’t be frozen (like a Paypal account can be)b) Your coins can’t be trackedc) Your coins can’t be taxedd) Transaction costs are extremely low (sorry credit card companies)
  • An individual with the name -- or perhaps handle -- of Satoshi Nakamoto first wrote about bitcoins in a paper called Bitcoin: A Peer-to-Peer Electronic Cash System.

  • * We made this term up to describe the “good people” of the internet who believe in the fundamental rights of individuals to be free, have free speech, fight hypocrisy and stand behind logic, technology and science over religion, political structure and tradition. These are the people who build and support things like Wikileaks, Anonymous, Linux and Wikipedia. They think that people can, and should, govern themselves. They are against external forms of control such as DRM, laws that are bought and sold by lobbyists, and religions like Scientology. They include splinter groups that enforce these ideals in the form of hacktivism, such as the takedown of the Sony Playstation Network after Sony tried to prosecute a hacker for unlocking its console.

    wow it's frigthening! it's the dream of every anarchist, every drug, arm, human dealer! the world made as a global fiscal paradise... the idea is clever however it will not replace real money because 1 - no one will build a fortune on bitcoin if a technological breakthrough can ruin them 2 - government never allowed parallel money to flourish on their territory, so it will be almost impossible to change bitcoin against euros or dollars

    interesting stuff anyone read cryptonomicon by neal stephenson? similar theme.
  •  
    :) yes. One of the comments on reddit was precisely drawing the parallels with Neal Stephenson's Snowcrash / Diamond Age / Cryptonomicon. Interesting stuff indeed. It has a lot of potential for misuse, but also opens up new possibilities. We've discussed recently how emerging technologies will drive social change. Whether it's the likes of NSA / CIA who will benefit the most from the Twitters, Facebooks and so on, by gaining greater power for control, or whether individuals are being empowered to at least an identical degree. We saw last year VISA / PayPal censoring WikiLeaks... Well, here's a way for any individual to support such an organization, in a fully anonymous and uncontrollable way...

    One of my colleagues has made a nice, short write-up about BitCoin: http://www.pds.ewi.tudelft.nl/~victor/bitcoin.html
  •  
    very nice analysis indeed - thanks Tamas for sharing it!
  •  
    mmm I'm not an expert but it seemed to me that, even if these criticisms are true, there is one fundamental difference between the money you exchange on internet via your bank, and bitcoins. The first one is virtual money and the second one aims at being real, physical, money, even if digital, in the same way as banknotes, coins, or gold.
  •  
    An algorithm wanna-be central bank issuing untraceable tax free money between internet users? not more likely than the end of the world supposed to take place tomorrow, in my opinion. Algorithms don't usually assault women though !:P
  •  
    well, most money is anyway just virtual and only based on expectations and trust ... (see e.g. http://en.wikipedia.org/wiki/Money_supply) and thus if people trust that this "money" has some value in the sense that they can get something of value to them in exchange, then not much more is needed it seems to me ...
  •  
    @Leopold: ok let's use the rigth words then. Bitcoin aim at being a currency ("physical objects generally accepted as a medium of exchange" from wikipedia), different than the "demand deposit". In the article proposed by Tamas he compares what cannot be compared (currencies, demand deposits and their mean of exchange). The interesting question is wether one can create a digital currency which is too difficult to counterfeit. As far as I know, there is no existing digital currency except this bitcoins (and maybe the currencies from games as second life and others, but which are of limited use in real world).
  •  
    well of course money is trust, and even more loans and credit and even more stock and bond markets. It all represents trust and expectations. However since the first banks 500 years ago and the first loans etc. etc., and as well the fact that bonds and currencies bring down whole countries (Greece lately), and are mainly controlled by large financial centres and (central) banks, banks have always been on the winning side no matter what and that isn't going to change easily. So if you are talking about these new currencies it would be a new era, not just a new currency. So should Greece convert its debt to bitcoins ;P ?
  •  
    well, from 1936 to 1993 the central bank of france was owned by the state and was supposed to serve the general interest...

    Looks really cool! And it's open source :)
  •  
    Don't know if you've noticed, but the current version is becoming more and more usable... did you try it already in your collaborative work?
  •  
    We've used it a bit with Juxi and Leopold for the work on the new issue of acta futura, and I think it is quite nice. The problem right now is that only a few people in the team have an account (and I have exhausted my invitations). Maybe you have one or two you are willing to share? :)

Hygromorphs: from pine cones to biomimetic bilayers - Interface - 0 views

  •  
    This is about biological and technical hygromorphs, i.e. structures that change shape according to humidity. Next to pine cones, there is also a cool study on wheat awns which drill themselves into the soil just by daily variance of air humidity. Biomimetics would be passively controlled acutators or humidity driven valves in space station to open/close dehumidification devices.
  •  
    Interesting, but only an abstract... do you have the full paper ?
  •  
    Not yet. There is also some other nice mechanism of wheat awns and how they use changes in humidity to anchor in soil. Would maybe fit with the above mentioned work of oisin.
