Bloomberg - The Only Crypto Story You Need - 0 views

  •  
    We're obviously not crypto-bros in the team, but this lengthy article is nonetheless very much worth a read to try to make sense of all this madness. Written by an expert in economics and finance, doesn't hold back any punches!

Optimised spatial planning to meet long term urban sustainability objectives - ScienceDirect - 3 views

  •  
    for the ACT architects .... Can we do the same for the Moon Village? We brainstorm on some mathematical simplified objectives for growing the settlement (taking inputs from the modular growth, resources, terrain suitability etc ....), we define some simple rules for growth and we optimize. ..... easy peasy (i am serious)
  •  
    i agree, with most of the parameters that would actually be really cool. but doesn't it get very messy once economy plays a large factor?
  •  
    We can start studying the ideal case, or add also some economical constraints on the settlement layout ...

A harsh critics to GCMs from Judith Curry - 2 views

  •  
    "By extension, GCMs are not fit for the purpose of justifying political policies to fundamentally alter world social, economic and energy systems. It is this application of climate model results that fuels the vociferousness of the debate surrounding climate models."
  •  
    but you know wo these global warming policy foundation is, do you? they are the main advocacy group for climate change deniers in the UK, nothing scientific to start with; fine to post here reasonable scientific papers criticising global climate models but please not this shit

The chips are down for Moore's law : Nature News & Comment - 4 views

  •  
    Super lol for all those who abused of the law in their slides / opinions / decisions ..
  •  
    I used the law in some slides :-)! This sentence is more or less the summary "The end of Moore's law is not a technical issue, it is an economic issue,". As Moore's himself recognized last year, the Moore's law itself is a pretty wild extrapolation of one exponential growth when there were only 5 experimental points. It is remarkable however how the semiconductor industry grabbed this and made every single effort to make it true. This effort was rewarded by turning semiconductor industry into one of the most important industries worldwide. Now these are challenging times indeed, and "when tide is gone, we realize who was swimming naked"...
  •  
    The "law" is one of the most successful concrete predictions of the technological future... Still very impressive and a lot more long-lived than Moore had probably ever dreamed of :)

Exploring gambles reveals foundational difficulty behind economic theory - 3 views

  •  
    In the wake of the financial crisis, many started questioning different aspects of the economic formalism. Here a mathematical "dynamic" alternative to economic utility theory (which has also been the target of some famous recent attacks, see prospect theory) is developed and applied to the St. Petersburg coin tossing paradox. A good read at http://scitation.aip.org/content/aip/journal/chaos/26/2/10.1063/1.4940236

    Love this type of friday afternoon research questions. There is also a now famous scene in the movie Clerks discussing the loss of independent contractors lives as the Death Star was being build.. https://www.youtube.com/watch?v=iQdDRrcAOjA

    That analysis is quite crappy and is easily demolished in the video's comments.

Reality - Almost No Patented Discoveries Ever Get Used @WIRED - 3 views

  •  
    The unspoken reality is that the U.S. patent system creates a market so constricted by high transaction costs and legal risks that it excludes the vast majority of small and mid-sized businesses and prevents literally 95 percent of all patented discoveries from ever being put to use to create new products and services, new jobs, and new economic growth.

Enhanced Oil Recovery Powered by Solar - 0 views

    instead of using the solar generated steam to generate electricity, it seems to make economic sense to use it to pump more oil out of the ground ...

AI, Robotics, and the Future of Jobs | Pew Research Center's Internet & American Life Project - 0 views

  • Some 1,896 experts responded to the following question: The economic impact of robotic advances and AI—Self-driving cars, intelligent digital agents that can act for you, and robots are advancing rapidly. Will networked, automated, artificial intelligence (AI) applications and robotic devices have displaced more jobs than they have created by 2025?

Nasa-funded study: industrial civilisation headed for 'irreversible collapse'? - 4 views

  •  
    Sounds relevant. Does ESA need to have a position on this question?
  •  
    This was on Slashdot now, with a link to the paper. It quite an iteresting study actually. "The scenarios most closely reflecting the reality of our world today are found in the third group of experiments (see section 5.3), where we introduced economic stratification. Under such conditions, we find that collapse is difficult to avoid."
  •  
    Interesting, but is it new? In general, I would say that history has shown us that it is inevitable that civilisations get replaced by new concepts (much is published about this, read eg Fog of War by Jona Lendering on the struggles between civilisations in ancient history, which have remarkably similar issues as today, yet on a different scale of course). "While some members of society might raise the alarm that the system is moving towards an impending collapse and therefore advocate structural changes to society in order to avoid it, Elites and their supporters, who opposed making these changes, could point to the long sustainable trajectory 'so far' in support of doing nothing." I guess this bang on it, the ones that can change the system, are not benefitted by doing so, hence enrichment, depletion, short term gain remain and might even accelerate to compensate for the loss in the rest of the system.

Asteroid mining could lead to self-sustaining space stations - VIDEO!!! - 5 views

  •  
    Let's all start up some crazy space companies together: harvest hydrogen on Jupiter, trap black holes as unlimited energy supplies, use high temperatures close to the sun to bake bread! Apparently it is really easy to do just about anything and Deep Space Industries is really good at it. Plus: in their video they show Mars One concepts while referring to ESA and NASA.
  • ...3 more comments...
  •  
    I really wonder what they wanna mine out there? Is there such a high demand on... rocks?! And do they really think they can collect fuel somewhere?
  •  
    Well they want to avoid having to send resources into space and rather make it all in space. The first mission is just to find possible asteroids worth mining and bring some asteroid rocks to Earth for analysis. In 2020 they want to start mining for precious metals (e.g. nickel), water and such.They also want to put up a 3D printer in space so that it would extract, separate and/or fuse asteroidal resources together and then print the needed structures already in space. And even though on earth it's just rocks, in space a tonne of them has an estimated value of 1 million dollars (as opposed to 4000 USD on Earth). Although I like the idea, I would put DSI in the same basket as those Mars One nutters 'cause it's not gonna happen.
  •  
    I will get excited once they demonstrate they can put a random rock into their machine and out comes a bicycle (then the obvious next step is a space station).
  •  
    hmm aside from the technological feasibility, their approach still should be taken as an example, and deserve a little support. By tackling such difficult problems, they will devise innovative stuffs. Plus, even if this doom-to-fail endeavour may still seem you useless, it creates jobs and make people think... it is already a positive! Final word: how is that different from what Planetary Resources plan to do? It is founded by a bunch of so-called "nuts" ... (http://www.planetaryresources.com/team/) ! a little thought: "We must never be afraid to go too far, for success lies just beyond" - Proust
  •  
    I don't think that this proposal is very different from the one by Planetary Resources. My scepticism is rooted in the fact that - at least to my knowledge - fully autonomous mining technology has not even been demonstrated on Earth. I am sure that their proposition is in principle (technically) feasible but at the same time I do not believe that a privately funded company will find enough people to finance a multi-billion dollar R&D project that may or may not lead to an economically sensible outcome, i.e. generate profit (not income - you have to pay back the R&D cost first) within the next 25 years. And on that timescale anything can happen - for all we know we will all be slaves to the singularity by the time they start mining. I do think that people who tackle difficult problems deserve support - and lots of it. It seems however that up till now they have only tackled making a promotional video... About job creation (sorry for the sarcasm): if usefulness is not so important my proposal would be to give shovels to two people - person A digs a hole and person B fills up the same hole at the same time. The good thing about this is that you can increase the number of jobs created simply by handing out more shovels.

Schumpeter: More than just a game | The Economist - 3 views

    remember the discussion I tried to trigger in the team a few weeks ago ...
  • ...5 more comments...
  •  
    main quote I take from the article: "gamification is really a cover for cynically exploiting human psychology for profit"
  •  
    I would say that it applies to management in general :-)
  •  
    which is exactly why it will never work .... and surprisingly "managers" fail to understand this very simple fact.

    ... "gamification is really a cover for cynically exploiting human psychology for profit" --> "Why Are Half a Million People Poking This Giant Cube?" http://www.wired.com/gamelife/2012/11/curiosity/
  •  
    I think the "essence" of the game is its uselessness... workers need exactly the inverse, to find a meaning in what they do !
  •  
    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

    why are video games so much different than collecting stamps or spotting birds or planes ? One could say they are all just hobbies

First circuit breaker for high voltage direct current - 2 views

  •  
    Doesn't really sound sexy, but this is of utmost importance for next generation grids for renewable energy.
  •  
    I agree on the significance indeed - a small boost also for my favourite Desertec project ... Though their language is a bit too "grandiose": "ABB has successfully designed and developed a hybrid DC breaker after years of research, functional testing and simulation in the R&D laboratories. This breaker is a breakthrough that solves a technical challenge that has been unresolved for over a hundred years and was perhaps one the main influencers in the 'war of currents' outcome. The 'hybrid' breaker combines mechanical and power electronics switching that enables it to interrupt power flows equivalent to the output of a nuclear power station within 5 milliseconds - that's as fast as a honey bee takes per flap of its wing - and more than 30 times faster than the reaction time of an Olympic 100-meter medalist to react to the starter's gun! But its not just about speed. The challenge was to do it 'ultra-fast' with minimal operational losses and this has been achieved by combining advanced ultrafast mechanical actuators with our inhouse semiconductor IGBT valve technologies or power electronics (watch video: Hybrid HVDC Breaker - How does it work). In terms of significance, this breaker is a 'game changer'. It removes a significant stumbling block in the development of HVDC transmission grids where planning can start now. These grids will enable interconnection and load balancing between HVDC power superhighways integrating renewables and transporting bulk power across long distances with minimal losses. DC grids will enable sharing of resources like lines and converter stations that provides reliability and redundancy in a power network in an economically viable manner with minimal losses. ABB's new Hybrid HVDC breaker, in simple terms will enable the transmission system to maintain power flow even if there is a fault on one of the lines. This is a major achievement for the global R&D team in ABB who have worked for years on the challeng

The Emerging Revolution in Game Theory - Technology Review - 2 views

  • The world of game theory is currently on fire. In May, Freeman Dyson at Princeton University and William Press at the University of Texas announced that they had discovered a previously unknown strategy for the game of prisoner's dilemma which guarantees one player a better outcome than the other. That's a monumental surprise. Theorists have studied Prisoner's Dilemma for decades, using it as a model for the emergence of co-operation in nature. This work has had a profound impact on disciplines such as economics, evolutionary biology and, of course, game theory itself. The new result will have impact in all these areas and more.
