  1. Re:We tried to get HP to do this... on Idea Stock Exchange · · Score: 2, Informative
    It was during the transition to Carly but it never got high enough up to be directly attributable to the executive suite.

    Indeed, executive decision support systems like this are precisely what the executive suite needs and it tends to be the layers just below them that are the most resistant so it's a catch-22. The executives typically have the mentality of the stock analysts and their immediate underlings are all-too-aware that upon this weakness their jobs depend.

  3. Russ George on Fleischmann to Work on Commercial Fusion Heater · · Score: 1
    The person to pay attention to here is Russ George.

    He's the principle behind the business and is also behind another business with similarly profound potential: Planktos, which purports to be pursuing the use of iron fertilization to sequester carbon via oceanic autotrophism. I hope he's not a con-artist or kook but the odds are not high he is for real. This will require some serious due diligence for those venture capitalists who are frustrated with the poor returns now poisoning software systems.

  4. Scalability on SpaceX's Falcon 1 Destroyed During Maiden Voyage · · Score: 1

    Well, of course, if the engine isn't scalable to any great degree then the approach talked about by Walker would have to, during development in order to keep costs down, decouple vehicle from engine development.

  5. The article does mention development on SpaceX's Falcon 1 Destroyed During Maiden Voyage · · Score: 1
    Suppose we translate these figures, almost incomprehensible by modern standards (three hundred launch vehicles expended in the development program!) into quasi-modern terms. Consider an orbital launch vehicle two-stage, say, clean and green thanks to LH2/LOX propulsion in all stages. Engines: J2 or RL10s or follow-on uprated versions (we'll have plenty of opportunity to develop them and phase them in). A simple two stage cylindrical stack like Titan II, with GPS or ground-commanded navigation. Payload interface is a big ring with bolt-holes and a standard fairing with plenty of volume inside.

    The habits of the development program carry over to production/operation. The only way you can afford 300 launch vehicles is to make them small and if those are the basis of your development for orbital craft then you have to make sure the entire process, for manufacture to launch operation is scalable.

  6. A launch a day keeps the high costs away on SpaceX's Falcon 1 Destroyed During Maiden Voyage · · Score: 5, Informative
    One of the things that John Carmack does correctly is lots of small flights with the possibility to scale upon success. John Walker wrote a paper about this approach (restricted to expendables) called "A Rocket a Day Keeps the High Costs Away". It's good advice. It's too bad more people (to be fair, such as John Walker himself) don't take it to heart.

  7. It's zombie war on Dismantling the Myth of IT Being a Dead-End Career · · Score: 0, Offtopic

    What's going on is actually warfare. Zombie money is being killed. Unfortunately, there is a lot of zombie money being created all the time because of the way the tax system subsidizes property rights. So the zombie money can kill a lot of people before it finally dies, and if the death rate of the zombie money isn't higher than the rate the government creates it, it can keep killing the people for a very very long time.

    Well, actually things could get interesting if you just made Rand's capitalism self-consistent by admitting that there is no moral responsibility to protect the property rights of others. At that point things very quickly stop favoring mere possession of wealth and start favoring creation thereof.

  11. The real question... on The Twists of History and DNA · · Score: 0, Troll
    25 years ago E. O. Wilson, in "On Human Nature" described the reasons to believe that 50 generations could be enough to cause substantial adaptation to moderate selective pressures. For his trouble Wilson was attacked as a "fascist" by fellow "scientists" at Harvard: Lewontin and Gould and an entire genre of popular "science" books and articles were spawned by the mid-Atlantic press.

    It turns out they were wrong to do this but really the posturing about 19th century beliefs being based on little more than base prejudice isn't much better than Lewontin and Gould. The Boasian anthropologists were just as politically motivated as their counterparts of the late 19th and early 20th century. The Boasians were more successful in putting forward their agenda not because their arguments were more sound but because they, like Lewontin and Gould, had better public relations.

    Men of Darwin's era weren't as stupid as we wish they were and we wish they were stupid because if they weren't then we would have to face how much damage has been done to scientific progress in the fields of human culture in the name of fighting racism and prejudice.

    The real question is how can we get beyond this nonsense and come to consilience between various fields of human knowledge of humanity so we can make human societies more sustainable and humane?

  12. Freedom of speech isn't fundamental on ISP Fined $5000 For Hate Content · · Score: 0
    As I said to some white nationalists when David Irving was arrested:

    Let's not get the cart before the horse.

    Freedom of speech is not a fundamental human right.

    Indeed, freedom of association is the sole fundamental human right.

    Freedom of speech can be constructed from freedom of association by the mutually consenting association between people who believe in freedom of speech and therefore practice it within the societies they form.

    There is a war to be fought but it is not over freedom of speech--rather it is over the opposition to freedom of likeminded people to form societies with territorial allocation to them within which they are able to live their beliefs without interference or parasitism from others.

    For the enhancement of scientific knowlege and the required development of advanced technology, A National Science Trust shall be established, with funding authorized by Congress, for the purchase of information about the natural world from Eligible Parties (private entities owned and controlled by other such entities in the U.S. or its unified free- trade partners). No less than 2/3 of the components and services used by the Eligible Parties to acquire this information must be obtained from other Eligible Parties.

    The National Academy of Sciences shall identify areas of scientific interest in which the quality of research results are quantifiable -- primarily in terms of information content. Examples of these kinds of research results are: DNA sequencing (human genome project), digital imaging of various phenomena (astronomical, planetary, terrestrial ozone-layer monitoring), quantitative behavior of systems in microgravity, quantitative mineral assay of various sites (terrestrial and nonterrestrial), etc.

    A dollar amount, to be established in conjunction with Congress, shall be associated with each informative item and with varying degrees of accuracy of the information. That dollar amount will then be appropriated to The Trust to be paid out only in the event that an Eligible Party has delivered new information on the associated item of interest to a designated recipient. When a measurement has already been made, payout will be limited to information value corresponding to the increased confidence level of the measurement (e.g. additional significant bits or fractions thereof). In areas where an information flow is required (periodic sampling) the value of various sampling frequencies at the various degrees of accuracy (significant bits) will be included in the valuation of the measurement. Duplicate information flows will share the cash flow evenly. For superior information flows, the incremental increase in accuracy will enjoy less diluted access to funding flows allocated to those incremental increases in accuracy.

    Income on The Trust will be used to adjust The Trust for inflation. Additional income from The Trust may be used to fund items within The Trust. In the event that an item is measured by a Party which is not an Eligible Party, and that information is available to the designated recipient -- the corresponding funding will be redistributed within The Trust. After-inflation losses will be redistributed within The Trust, deactivating items which are not currently being pursued by any Eligible Party.

  19. The Two Fallacies: Ore grade and interest rates on The Financial Future of Space Travel · · Score: 1
    People who look to asteroid mining of metals for terrestrial use miss two fundamental factors:

    1. Ore grade just isn't that good compared to what you find on earth. Extracting platinum from a solid block of nickel amalgam is really energy intensive, and the other "stony" asteroids have not gone through the hydrothermal concentration of metals of the terrestrial deposits.
    2. The time it takes for a piece of capital equipment to return any materials to earth from an asteroid is enormous compared to the delivery of lunar mass to earth orbit. Since any mass in earth orbit is worth hundreds of dollars a pound and the time is so short for delivery, it makes a lot more sense to use lunar material in earth orbit than it does to use asteroidal material on the earth's surface.

    Subject: Re: The C-Prize

    Hutter's AIXI, http://www.idsia.ch/~marcus/ai/paixi.htm makes another argument for the connection between compression and AI that is more general than the Turing test. He proves that the optimal behavior of an agent (an interactive system that receives a reward signal from an unknown environment) is to guess that the environement is most likely computed by the shortest possible program that is consistent with the behavior observed so far. In other words, the most likely outcome for any experiment is the one with the simplest explanation, where "simplest" means the smallest program that could model what you currently know about the universe.

    He gives a formal proof, but it basically says that the only possible distribution of the infinite set of programs (or strings) with nonzero probability is one which favors shorter programs over longer ones. Given any string of length n with probability p > 0, there are an infinite set of strings longer than n, but only a finite number of these can have probability higher than p.

    -- Matt Mahoney

    Matt Mahoney is the author of Text Compression as a Test for Artificial Intelligence which states:
    It is shown that optimal text compression is a harder problem thanartificial intelligence as defined by Turing's (1950) imitation game; thus compression ratio on a standard benchmark corpuscould be used as an objective and quantitative alternative test for AI (Mahoney, 1999).
