    Globular clusters in our galaxy would be the remnants of dwarf galaxies eaten by our galaxy the milky way ! This assumption is quite revolutionary and would support an accretion model of the universe rather than the formation of huge galaxies. So what about the formation of giant black holes in the center of galaxies...?

    I love the linked article provided by Johannes! It expresses very elegantly why I still fail to understand even extremely smart and busy people in my view apparently waiting their time in playing computer games - but I recognise that there is something in games that we apparently need / gives us something we cherish .... "In fact, half a million players so far have registered to help destroy the 64 billion tiny blocks that compose that one gigantic cube, all working in tandem toward a singular goal: discovering the secret that Curiosity's creator says awaits one lucky player inside. That's right: After millions of man-hours of work, only one player will ever see the center of the cube. Curiosity is the first release from 22Cans, an independent game studio founded earlier this year by Peter Molyneux, a longtime game designer known for ambitious projects like Populous, Black & White and Fable. Players can carve important messages (or shameless self-promotion) onto the face of the cube as they whittle it to nothing. Image: Wired Molyneux is equally famous for his tendency to overpromise and under-deliver on his games. In 2008, he said that his upcoming game would be "such a significant scientific achievement that it will be on the cover of Wired." That game turned out to be Milo & Kate, a Kinect tech demo that went nowhere and was canceled. Following this, Molyneux left Microsoft to go indie and form 22Cans. Not held back by the past, the Molyneux hype train is going full speed ahead with Curiosity, which the studio grandiosely promises will be merely the first of 22 similar "experiments." Somehow, it is wildly popular. The biggest challenge facing players of Curiosity isn't how to blast through the 2,000 layers of the cube, but rather successfully connecting to 22Cans' servers. So many players are attempting to log in that the server cannot handle it. Some players go for utter efficiency, tapping rapidly to rack up combo multipliers and get more

[1107.5728] The network of global corporate control - 1 views

arxiv.org/1107.5728

economics social_network

shared by pacome delva on 28 Nov 11 - No Cached
  • Abstract: The structure of the control network of transnational corporations affects global market competition and financial stability. So far, only small national samples were studied and there was no appropriate methodology to assess control globally. We present the first investigation of the architecture of the international ownership network, along with the computation of the control held by each global player. We find that transnational corporations form a giant bow-tie structure and that a large portion of control flows to a small tightly-knit core of financial institutions. This core can be seen as an economic "super-entity" that raises new important issues both for researchers and policy makers.

Facebook is buying WhatsApp for ~ $ 19e9 - 1 views

    That is about € 14e9 - enough to pay more than a million YGTs for half a year. Could we use maybe just half a million YGTs for half a year to build a similar platform and keep the remaining € 7e9 for ourselves? Keep in mind that WhatsApp only has 45 employees (according to AllThingsD: http://goo.gl/NtJcSj ). So we would have an advantage > 10000:1. On the other hand does this mean that every employee at WhatsApp gets enough money now to survive comfortably for ~5000 years or will the inevitable social inequality strike and most people get next to nothing while a few get money to live comfortably for ~1000000 years? Also: Does Facebook think about these numbers before they pay them? Or is it just a case of "That looks tasty - lets have it"? Also (2): As far as I can see all these internet companies (Google, Facebook, Yahoo, WhatsApp, Twitter...) seem to make most of their income from advertising. For all these companies together that must be a lot of advertising money (turns out that in 2013 the world spent about $ 500 billion on advertising: http://goo.gl/vYog15 ). For that money you could of course have 20 million YGTs roaming the Earth and advertising stuff door-to-door... ... ...

    Jo, thats just brilliant... 500billion USD total on advertising, that sounds absolutely ridiculous.. I always wondered whether this giant advertisement scheme is just one big 'ponzi'-like scheme waiting to crash down on us one day when they realize, cat-picture twittering fb-ing whatsapping consumers just aint worth it..
  • Juxi Leitner on 20 Feb 14
     
    The whole valuation of those internet companies is a bit scary. Things like the Facebook and Twitter ipo numbers seem just ridiculous.
  • Paul N on 21 Feb 14
     
    Facebook is not really so much buying into a potential good business deal as much as it's buying out risky competition. Popular trends need to be killed fast before they take off the ground too much. Also the amount of personal data that WhatsApp is amassing is staggering. I have never seen an app requesting so many phone rights in my life.

    I attended a presentation by H. Hemmati, formerly at NASA's JPL, now at Facebook working to "connect the unconnected" during a panel session of the Workshop "Shining light on future space optical communications". I gather that they are targeting a combined strategy of HAP (with solar powered planes at 20-25 km), balloons and satellites. The rationale behind is that each solution is best suited for different population density zones, i.e. satellites while expensive (total cost of 100MUSD after Hemmati) are the only way to provide internet in remote zones, while balloons seem to be one inexpensive solution for densely populated areas. Funfact: he mentioned that the main drawback will be some crashes of HAP elements...

    Facebook announced they are ready to test of of their High Altitude Platform element, a drone of the size of a Boeing 737. See the new here http://phys.org/news/2015-07-facebook-ready-giant-drone-internet.html?utm_source=nwletter&utm_medium=email&utm_content=ctgr-item&utm_campaign=daily-nwletter. It seemed interesting for me that they are developing also a reliable optical communication between this element and scattered ground stations.
