  1. Re:SpaceDev, the engine designer will reuse the te on SpaceShipOne to Try for Space on Monday · · Score: 1
    The technology used in this launch is going to be reused by SpaceDev to put satellites up for only $5 million a piece. This illustrates the direct effect of the X-prize.

    Uh... not quite. Although everyone keeps talking about this launch as if it were really a spaceflight, it's just a high-altitude airplane flight.

    In Monday's flight to 100KM the top speed will probably be around Mach 3. The speed needed to achieve a stable orbit is about 15 times faster.

    SpaceShipOne can't begin to achieve those kind of speeds.

    Once you are in orbit, reentry becomes a serious problem because of atmospheric friction. If SpaceShipOne actually could get into orbit, it would burn up on reentry, because it would need to be coated with refractory material like the space shuttle, or an ablative shield, like the Apollo, Soyuz and other disposable craft.

    Although SpaceShipOne is a very impressive engineering feat, it is still very far from being a real space craft.

    For that, we'll probably have to wait for SpaceShipThree or SpaceShipFive.

    Oh, in the video monitor the cloak is sorta transparent. Why? Because they're doing an absolutely standard compositing effect IN THE VIDEO MONITOR.

    The cloak is NOT transparent. It's just a piece of blue screen and they composite the background on it. But only if you look at a video monitor. In real life, the cloak is entirely opaque and it's just a grey cloak.

    I asked the professor how long it would be before they had a real working prototype and he said "Maybe 20 years."

    In other words, they have nothing. Just a concept. And it's not even a new concept. It's an old science fiction concept.

    There is nothing to see here. It's just PR and a very standard old-hat video effect.

    There is such a thing for humans, at least for women. Check out this abstract Psychological state and mood effects of steroidal chemosignals in women and men.


    Psychological state and mood effects of steroidal chemosignals in women and men.

    Jacob S, McClintock MK.

    Department of Psychology, The University of Chicago, 5730 South Woodlawn Avenue, Chicago, Illinois 60637, USA.

    We tested the hypothesis that isolated steroids, claimed to act like pheromones, affect human psychological state or mood. In the first experiment, we established that two steroids, Delta4, 16-androstadien-3-one and 1,3,5(10)16-estratetraen-3-ol, modulated emotional states within 6 min of exposure. In men and women, neither steroid had specific effects on states of alertness or negative-confused mood. However, both steroids increased positive stimulated mood state in women but decreased it in men. These psychological findings do not parallel the reported sexually specific effects of these two steroids on the surface potential activity of putative vomeronasal epithelium. In a second experiment on women, we replicated that Delta4,16-androstadien-3-one modulated their general mood state, even when women were not aware of its odor and gave identical olfactory descriptions for the steroid and the control carrier solutions. In this within-subjects, repeated-measures experiment, androstadienone prevented the deterioration in general mood which occurred during exposure to the clove oil carrier solution in the laboratory environment. Thus, androstadienone appears to modulate affect, rather than releasing stereotyped behaviors or emotions. It is premature to call these steroids human pheromones. They are nonetheless psychologically potent, mandating future work delineating their function-i.e., whether these steroids are communicative chemosignals, context specific, or related to unconscious associations. In light of these modulatory effects and the complexity of human behavior, the function of chemosignals and pheromonal systems in a variety of species may need to be expanded to include the concept of modulators, as well as the traditional releasers, primers, and signaling compounds.

    I actually found this reference on the site of a company that sells pheromone cologne, in a section describing the basis for their product claims. They're implying at least that they sell either the same pheromones mentioned in that study, or something with similar results.

    Makes me curious...

  6. Expectation of Privacy on Google's Gmail Goes Into Beta for Blogger Users · · Score: 2, Interesting

    What privacy advocates have objected to about Gmail is that, by scanning mail and displaying an ad next to it, the service reduces the "expectation of privacy".

    "Reasonable expectation of privacy" is a legal term which, among other things, influences what the courts allow the government to do when snooping on people without a warrent.

    For examples of this, look for instance at the case law surrounding trash.

    The courts have ruled that it's perfectly OK for law enforcement agencies to pick through your trash because people do not have an "expectation of privacy" when they throw things away.

    The danger with Gmail is that it starts to erode the generally-held idea that it is wrong for anyone to read someone else's email. Sure, it's just software and sure, no one is actually reading it. But the contextual ads may give the impression that the mail is read, therefore allowing the courts to rule later that there is no "reasonable expectation of privacy" in email, and allowing the government to snoop through your mail at will.

    This isn't coming tomorrow, but it's one of the main objections privacy advocates have to Gmail. Similar sentiments from other privacy advocacy groups are expressed in this article

    It's amazing how little you know, and how authoritatively you post.

    In fact, the People's Republic of China does not recognise patents of other countries, and does basically no patent enforcement at all. It also requires a patent holder to grant a license to anyone who wants one, and gives a judge the right to make up the terms.

    This is completely false. Obviously you've never applied for a patent.

    When you apply for a U.S. patent, what you get (if anything) is a patent enforcable for things which are made or sold in the USA. That's it.

    In order to apply for any other patents, you have to first file a PCT (Patent Cooperation Treaty) application (about $5000 extra) with the USPTO. This gives you the RIGHT to file additional international patents within the next 36 months.

    If you DO want to file international patents you have to file EACH ONE INDIVIDUALLY in the country you want it filed. Each one has to be translated into that country's language and must be put into their particular format.

    If you decide to file in every country, it will end up costing perhaps $200K or so more (depending on the length of the patent and therefore translation fees). But some countries (notably Taiwan) are not signers to the PCT, and have to be filed entirely separately.

    There are really only two alternative explanations for this:

    1) Google tried to apply some kind of filter with good intentions but it's really buggy and is banning thousands of sites who did nothing wrong.

    2) Google is cynically banning thousands of sites in hopes that their Adwords revenue will jump pre-IPO.

    It has been suggested that they are doing this to force businesses to use Adwords so that their valuation can be increased in the IPO.

    What apparently happened was that for any keywords which are actively bid for in Adwords, Google applied a filter making it very hard for legitimate businesses to get any ranking in normal search results.

    Here is an application which was built to show the difference between current and previous results (before the new keywords filters were applied by Google) www.scroogle.org/.

    This message has some good data and a summary of the argument.

    What makes this so worrying is that Google made its reputation on objectively good search results. If they are now distorting results in pursuit of cash, they're LESS objective than search engines which have explicit pay for placement, like Overture: in those search engines you can at least see which results are paid for and which are actually real.

    a) IBM wanted to charge a rather high fee for anyone to license the new bus, both to clone manufacturers and to card manufacturers.
    b) Card manufacturers found it more expensive to make cards for the new bus, partly because the traces required for the slot contacts had such a tight tolerance requirement.

    - The ability to integrate these inputs.
    - Output to your muscles to maintain balance, especially while walking or when stepping onto something uneven.
