  • BOUNCE BACK TIP: What goes down often bounces back even higher.

    happy

    Just as the rich get richer, studies show that often the happy get happier and the sad get sadder–because of simmering brain temperatures–also known as “resonance.”

    Happy thoughts all share the same resonance in the brain–and are shown to naturally attract the memory of other happy thoughts–also simmering at the same happy “resonance.”

    Chances are you’ve witnessed this theory of resonance with guitars. You know if you pluck the G string on one guitar, the G string on any nearby guitar will have “sympathetic resonance” and start to vibrate as well! If you haven’t experienced this, check it out! It’s very cool.

    Well, memories are “tuned in” at specific frequencies, based on the information they’re encoded with–like “This is high-level happy stuff” or “this is low-level miserable stuff.”

    Whatever resonance your present thoughts are simmering at (“high-level happy” or “low-level miserable”), they’ll attract memories of similar information. The result: When you’re happy, a stream of positive thoughts ensues. Ditto on simmering negative thoughts.

    The good news: Over time, negative brain resonances eventually simmer back up to their normal, daily, even-keeled midlevel set zones. When they do, that’s when the feeling of “rebounding” kicks in.

    So if lately you’ve been worried that you’re never going to feel like your normal self again, don’t. You’re biologically wired to return to your normal midlevel mood.

    Happiness Assignment: Create a Gratitude Journal. Record: Who do you love? What do you love? What do you love to do? Psychologists find that people who keep weekly gratitude journals end up feeling happier, more energetic, and more optimistic than those who don’t. So write down those people, things, and experiences that bring you joy, and keep your brain resonating at a happy temperature.

  • Will Google’s Italy Conviction Stick… Or Is The Problem In The Law?

    Most of the discussion around the conviction of three Google execs on criminal charges over a video uploaded to Google video (which none of those execs had anything to do with), rightly focused on the assault on basic common sense that the result created. Convicting three executives as criminals for actions they had absolutely nothing to do with, and which concern events where the company acted expeditiously once it was officially informed of the issue, just violates every concept of fairness. It’s hard to see how anyone can justify this sort of outcome (though, we’ve see a few people try).

    However, a separate question is whether or not the ruling has a real legal basis. Given some of the reports we’d received from some lawyers in Italy, the feeling was that this was perfectly within the bounds of Italian law (and some were upset that we’d even question that). There is some uncertainty, however, as to how this fits within wider EU law, which Italy must also abide by. The Citizen Media Law Project has a post that details why they think that the conviction won’t hold on appeal, suggesting that the judge misclassifed Google in determining whether or not the company qualified for EU-wide safe harbors for service providers.

    However, there are some other possibilities as well. Struan Robertson has a detailed post, looking at EU safe harbors, which notes two reasons why Google may have lost the case. The first is that, despite EU safe harbors, there’s actually a carve out for data privacy issues. Since the execs were acquitted on defamation issues, but still convicted on privacy violations, this might be correct. However, if that’s the case, it highlights exactly why this loophole is both silly and dangerous. Yes, privacy is very important, but it’s never going to make sense to put the liability for privacy violations on a third party directly. There’s nothing wrong with focusing on potential lawbreaking by those who created or uploaded the video — but blaming the platform used for hosting the video makes no sense at all.

    The second area that Robertson highlights is the one that prosecutors had definitely brought up in the case: that Google did have “notice” of the offending nature of the video prior to the official alert from the police. The prosecutors argued that the comments on the video should have served to alert Google. Again, this seems a bit ridiculous — given how many videos are uploaded every day, and how many comments are found on those videos.

    However, these issues all point to problems with EU law that really should be fixed. First, the safe harbors need to be clearer, so that it’s understood who or what is covered. Second, the “privacy” loophole needs to be closed. Yes, privacy is important, but nothing is so important that it should lead to jailing totally unrelated parties. Finally, the law needs to be much clearer on what constitutes official notice. As Robertson notes, there was a proposal made in the UK a little while back to clarify that very issue, and the politicians chose not to do so. When you leave the process open wide to interpretation like that, you get cases with nonsensical results, such as what happened in this case. Hopefully, Google wins on appeal, but in the meantime, Europe really should fix these problems with its current safe harbor laws.

    Richland, WA- When your kids ask you why they need to know math, tell them this.

    Today engineering students at Columbia Basin College took the freshmen at Delta High School outside and let them get hands-on experience with equipment works.

    The math students have been working with angles, and their teachers wanted to let them see and touch a real-life application.

    “It’s not just a couple of lines on a piece of paper,” says CBC Associate Professor Paige Wyatt. ” It has real meaning, a real use. The other nice thing is surveying is an excellent field to go into, so it could lead to some careers if the kids dive in an really enjoy it.”

    In case your kids ask, surveying helps engineers determine land boundaries and build straight and level roads.

    The uphill-downhill road of Ariccia

    Things seem to roll, flow and run uphill on this short patch of road near Ariccia, Italy

    Just outside of Rome, one can find respite from the smog, and traffic of the big city among them fresh air, beautiful surroundings, wonderful food and a road that seems to run in reverse.
    Known as an anti-gravity hill, this curious spot is popular in Rome and Italian national TV reported about it. As with other ‘anti-gravity hills’ It looks like a normal street in the woods with a gentle slope, but if you pour water or put a ball on the pavement it seems to go uphill! When one walks on the hill one “can clearly feel that going uphill is much easier than going downhill.” This of course should be a dead giveaway that something is amiss. If a blind man walked on this hill he would find it no stranger than any other hill, which in regards to gravity, it isn’t.
    Like other gravity hills throughout the world, the same explanations are generally given: a deviation in gravity, magnetic effects caused by huge underground metal deposits, and in this case volcanic activity in ancient times. There is however only one true cause, one which only effects those with sight. The effect is caused by the peculiar series of uphill and downhill stretches in which there is scarce or no view of the horizon. If one lays a level on the hill is shows that things are going downhill indeed…
    However it seems that even computers can get it wrong. Recently it has been pointed out that according to Google Maps the height of a succession of points on the road shows that according to Google things are indeed going uphill in defiance of gravity.

  • More Random And Arbitrary iPhone App Removals: WiFi Finders Disappear

    For a while the complaints used to be about Apple’s totally arbitrary process for choosing which apps get into the iPhone app store, but lately the complaints have been about Apple (again totally arbitrarily) removing apps that were already there. There were all those complaints about the sudden removal of “adult” apps (unless you were someone famous like Playboy, in which case Apple was fine with it), and now there are complaints that Apple suddenly and inexplicably has removed WiFi finders from the app store. While developers feel they need to keep developing for the iPhone given its footprint in the market, moves like this are going to keep pissing off developers quite a bit too. You can do that when you dominate the market, but it can come back to bite you later on.

  • Liz Cheney, “mockingbirds are tasty”

    Before the United States was ever born, one principle was clear to John Adams, when as a lawyer, he defended British soldiers in the wake of the Boston Massacre (and I’m reminded in comments — ironically, it’s the 240th Anniversary of that event):

    “The part I took in defense of captain Preston and the soldiers, procured me anxiety, and obloquy enough. It was, however, one of the most gallant, generous, manly and disinterested actions of my whole life, and one of the best pieces of service I ever rendered my country.”

    And from Adams, to Clarence Darrow, to the Scottsboro Boys to Stephen Jones defense of Timothy McVeigh right through to the latter’s execution this has been a time-honored principle of an idyllic America, whether conservative like Adams and Jones, or liberal like Darrow.

    But admiration for an Atticus Finch is no match for the visceral stupidity of Wolf Blitzer and the thuggish politics of a Liz Cheney. No, for them, lawyers following the highest principles of the calling are just another bunch of terrorist enablers.

    The daily right-wing slant of FoxNews and it’s hourly diatribes are, of course, bad enough, and the determination of every news medium to allow right-wing bullshit to be taken seriously rather than laughed at is depressing. But CNN’s Situation Room had all the intellectual acumen of ‘The Situation’ himself yesterday. It’s one thing for Blitzer to be bland and dumb — because he is — it’s another thing to add kerosene to the fires of undermining the best things about our system of government.

  • Slovakia: Unwanted Patriotism

    According to SME.sk (SLO), a draft bill by the Slovak National Party (SNS) will introduce “obligatory patriotism” in Slovakia beginning April 1:

    […] It is Monday morning. In every state-run […] school or university in Slovakia directors must have the national anthem performed in a way that every student is able to hear it. In the classrooms, in addition to the portrait of the president, there are also the state emblem, the national flag, the text of the anthem and the preamble to the constitution.

    This is how it is going to be like in every state school from April 1 [btw, traditional ‘fool's day'], as parliament members from the government coalition have approved the controversial patriotic law designed by SNS.

    […]

    Obligatory patriotism is not limited to schools. Coalition parliament members will bring it also to adults. At every sports event organized by national sports organizations the anthem will be performed. ‘Lightning over the Tatras‘ will also sound before parliament meetings, and at the beginning of local government and parliament meetings. Every officer entering civil service will have to take an obligatory oath of loyalty to the republic.

    […]

    “We will be bigger patriots,” promised Rafael Rafaj from SNS.

    […]

    Rafaj also said that the state media would have to broadcast the anthem at midnight.

    Other Slovak newspapers also point out that the new law is controversial. Pravda, for example, recalls (SLO) that the Soviet anthem was obligatory during the 1950s and publishes the question asked by school principals: who will pay the bills (the expected cost of the implementation of the law is about 1 million euro) when the ministry of education refuses to do it?

    Bloggers are against the new law, too, and there have been organized protests in front of the presidential palace and the parliament (two sample reports (SLO) are at Robert Mihaly's blog – here and here).

    Here is a short selection from thousands of netizens' comments (SLO):

    Trautiq:

    Strange but a very effective support of private schools.

    foobar2k:

    All it takes it to bring your child to school 10-15 minutes after lessons begin.

    pokaini:

    :-)) this is exactly what I will do every Monday too 🙂

    niau:

    Promises of loyalty are well known to SNS chief – in 2004 he promised loyalty to his third wife already… 😉

    Slovän:

    Not afraid, because there are no sanctions for breaking this law, but anyway I think it is not good. Especially the anthem at the beginning of every week. As a student of pedagogy, I perceive it quite negatively and directly because I have a positive attitude towards the anthem. The anthem has to be respected, but how can someone have respect for an anthem that will bother him this way?

    1qwerty1:

    It will end the same way as with the Russian language. It used to be obligatory, too, and let's be honest: who remembers even their [Cyrillic] letters now?

    mibosa:

    So what? I had experience with the Labor song, the Internationale and “Soyuz nerushimyj” [the Soviet anthem] – and I survived it. And the children will sing it and, believe me, they will have fun doing it.

    livik:

    I just wanna mention that I have no doubt that this president will submissively sign this pearl.

    ficobijec_no.1:

    During next year's census, it is necessary to write this in the ‘nationality' box: “Apache.”

    zlyzlyzlykapitalista:

    Good idea, the opposite to Comanches 🙂 [Comanche is in Slovakia a shortcut for ‘communist.' Comments that follow in this forum name various other nationalities that people have already chosen in the past census to make clear they were not members of the same nation as SNS members. In another discussion of this issue, an unverified news item was mentioned that claimed that in the Czech Republic such a big Eskimo minority had been created for the similar reasons that they already qualified for financial support from the government.]

    wladelny:

    Maybe a nephew of some parliament member owns a plant for printing of state symbols, the text of the anthem and the preambles? 😀

    hollywood:

    My God, don't we have other problems? I wonder how they are going to play the anthem: our education system even without this has no money – and now they have to buy new CDs.

    haskii86:

    Do not be afraid, SNS has suppliers who are waiting already.

    charl1:

    And is this the punishment that we have this government, my Lord? I promise I will be good, just don't let them govern more times! Amen.

    arway:

    At my command: “To love our dear Slovak homeland!” – “Always ready!”

  • Global Warming Money Trail

    The canard against climate skeptics been funded by big oil was always obviously a joke.  As noted the skeptics were typically retired experts who clearly devoted their own time and energy to qualifying the data.  No one was going to pay them a nickel to challenge the hugely promoted orthodoxy that global warming however real was humanities fault.
    Instead, they were starved of access to crucial data that obviously needed to be checked.
    This item outlines not only the persuasive supply of money available to push only one side of the debate, it spells out theirs primary motivation.  It was all about securitizing the global energy business in a way that benefited the usual suspects.  Except that Mother Nature chose to not go along with the gag.  Fifteen years of flat temperatures make the favored theory a bad joke that even a child can refute.
    The persuasiveness of the funding pressure has given us unending press releases discussing perfectly good science that then makes a bow of no consequence to global warming.  They are still doing it.
    It is all a massive effort to hit the globe with what is mostly a form of VAT on energy to benefit unelected self appointed elites who will purportedly manage this largesse.  At the present it is choking on a sudden burst of skepticism from the media.  What took them so long?
    In science, you do not give anyone’s evidentiary trail a bye. It is replicate and carefully review.  That may now be unavoidable for the climate science crowd.

                            
    The money trail
    4 MARCH 2010
    Somehow the tables have turned. For all the smears of big money funding the “deniers”, the numbers reveal that the sceptics are actually the true grassroots campaigners, while Greenpeace defends Wall St. How times have changed. 

    Sceptics are fighting a billion dollar industry aligned with a trillion dollar trading scheme. Big Oil’s supposed evil influence has been vastly outdone by Big Government, and even those taxpayer billions are trumped by Big-Banking. 

    The big-money side of this debate has fostered a myth that sceptics write what they write because they are funded by oil profits. They say, follow the money? So I did and it’s chilling. Greens and environmentalists need to be aware each time they smear with an ad hominem attack they are unwittingly helping giant finance houses. 

    FOLLOW THE MONEY


    Money for Sceptics: Greenpeace has searched for funding for sceptics and found $23 million paid by Exxon over 10 years (which has stopped). Perhaps Greenpeace missed funding from other fossil fuel companies, but you can be sure that they searched. I wrote the Climate Money paper in July last year, and since then no one has claimed a larger figure. Big-Oil may well prefer it if emissions are not traded, but it’s not make-or-break for them. If all fossil fuels are in effect “taxed”, consumers will pay the tax anyhow, and past price rises in crude oil suggest consumers will not consume much less fuel, so profits won’t actually fall that much. 

    But in the end, everyone spends more on carbon friendly initiatives than on sceptics– even Exxon: (how about $100 million for Stanford’s Global Climate and Energy Project, and $600 million for Biofuels research). Some will complain that Exxon is massive and their green commitment was a tiny part of their profits, but the point is, what they spent on scepticswas even less

    Money for the Climate Industry: The US government spent $79 billion on climate research and technology since 1989 – to be sure, this funding paid for things like satellites and studies, but it’s 3,500 times as much as anything offered to sceptics. It buys a bandwagon of support, a repetitive rain of press releases, and includes PR departments of institutions like NOAA, NASA, the Climate Change Science Program and the Climate Change Technology Program. The $79 billion figure does not include money from other western governments, private industry, and is not adjusted for inflation. In other words, it could be…a lot bigger.

    For direct PR comparisons though, just look at “Think Climate Think Change“: the Australian Government put $13.9 million into just one quick advertising campaign. There is no question that there are vastly more financial rewards for people who promote a carbon-made catastrophe than for those who point out the flaws in the theory.

    Ultimately the big problem is that there are no grants for scientists to demonstrate that carbon has little effect. There are no Institutes of Natural Climate Change, but plenty that are devoted to UnNatural Forces.

    It’s a monopsony, and the main point is not that the scientists are necessarily corrupted by money or status (though that appears to have happened to a few), but that there is no group or government seriously funding scientists to expose flaws. The lack of systematic auditing of the IPCC, NOAA, NASA or East Anglia CRU, leaves a gaping vacuum. It’s possible that honest scientists have dutifully followed their grant applications, always looking for one thing in one direction, and when they have made flawed assumptions or errors, or just exaggerations, no one has pointed it out simply because everyone who could have, had a job doing something else. In the end the auditors who volunteered — like Steve McIntyre and AnthonyWatts — are retired scientists, because they are the only ones who have the time and the expertise to do the hard work. (Anyone fancy analysing statistical techniques in dendroclimatology or thermometer siting instead of playing a round of golf?)

    Money for the Finance Houses: What the US Government has paid to one side of the scientific process pales in comparison with carbon trading. According to the World Bank, turnover of carbon trading reached $126 billion in 2008. PointCarbon estimates trading in 2009 was about $130 billion. This is turnover, not specifically profits, but each year the money market turnover eclipses the science funding over 20 years. Money Talks. Every major finance house stands to profit as brokers of a paper trade. It doesn’t matter whether you buy or sell, the bankers take a slice both ways. The bigger the market, the more money they make shifting paper. 

    BANKS WANT US TO TRADE MONEY…


    Not surprisingly banks are doing what banks should do (for their shareholders): they’re following the promise of profits, and urging governments to adopt carbon trading. Banks are keen to be seen as good corporate citizens (look, there’s an environmental banker!), but somehow they don’t find the idea of a non-tradable carbon tax as appealing as a trading scheme where financial middlemen can take a cut. (For banks that believe in the carbon crisis, taxes may well “help the planet,” but they don’t pay dividends.)

    The stealthy mass entry of the bankers and traders poses a major force. Surely if money has any effect on carbon emissions, it must also have an effect on careers, shareholders, advertising, and lobbying? There were over 2,000 lobbyists in Washington in 2008.

    Unpaid sceptics are not just taking on scientists who conveniently secure grants and junkets for pursuing one theory, they also conflict with potential profits of Goldman Sachs, JP Morgan, BNP Paribas, Deutsche Bank, HSBC, Barclays, Morgan Stanley, and every other financial institution or corporation that stands to profit like the Chicago Climate Exchange, European Climate Exchange, PointCarbon, IdeaCarbon (and the list goes on… ) as well as against government bureaucracies like the IPCC and multiple departments of Climate Change. There’s no conspiracy between these groups, just similar profit plans or power grabs.

    Tony Abbot’s new policy removes the benefits for bankers. Labor and the Greens don’t appear to notice that they fight tooth and nail for a market in a “commodity” which isn’t a commodity and that guarantees profits for big bankers. The public though are figuring it out.

    THE LARGEST TRADEABLE “COMMODITY” IN THE WORLD?


    Commissioner Bart Chilton, head of the energy and environmental markets advisory committee of the Commodity Futures Trading Commission (CFTC), has predicted that within five years a carbon market would dwarf any of the markets his agency currently regulates: “I can see carbon trading being a $2 trillion market.” “The largest commodity market in the world.” He ought to know. 

    It promises to be larger than the markets for coal, oil, gold, wheat, copper or uranium. Just soak in that thought for a moment. Larger than oil.

    Richard L. Sandor, chairman and chief executive officer of Climate Exchange Plc, agrees and predicts trades eventually will total $10 trillion a year.” That’s 10 thousand billion dollars.

    ONLY THE EMPIRICAL EVIDENCE MATTERS


    Ultimately the atmosphere is what it is regardless of fiat currency movements. Some people will accuse me of smearing climate scientists and making the same ad hominem attacks I detest and protest about. So note carefully: I haven’t said that the massive amount of funding received by promoters of the Carbon Catastrophe proves that they are wrong, just as the grassroots unpaid dedication of sceptics doesn’t prove them right either. But the starkly lop-sided nature of the funding means we’d be fools not to pay very close attention to the evidence. It also shows how vapid the claims are from those who try to smear sceptics and who mistakenly think ad hominem arguments are worth making.

    And as far as evidence goes, surprisingly, I agree with the IPCC that carbon dioxide warms the planet. But few realise that the IPCC relies on feedback factors like humidity and clouds causing a major amplification of the minor CO2 effect and that this amplification simply isn’t there.

    Hundreds of thousands of radiosonde measurements failed to find the pattern of upper trophospheric heating the models predicted, (and neither Santer 2008 with his expanding “uncertainties” nor Sherwood 2008 with his wind gauges change that). Two other independent empirical observations indicate that the warming due to CO2 is halved by changes in the atmosphere, not amplified.[Spencer 2007, Lindzen 2009, see also Spencer 2008]

    Without this amplification from water vapor or clouds the infamous “3.5 degrees of warming” collapses to just a half a degree — most of which has happened. 

    Those resorting to this vacuous, easily refutable point should be shamed into lifting their game. The ad hominem argument is Stone Age reasoning, and the “money” insult they throw, bounces right back at them — a thousand-fold.

  • High Energy Density Biofuel Advance



    This appears to be promising.  We have here a way to convert a portion of the biomass product stream into a high energy density fuel.  All prior work focused of ethanol which promised to be cheap and easy, but was also somewhat less energetic than we are used to.
    Some interesting advances have been made on that front, but the end product of ethanol has always been problematic, needing a proper retooling of engine design to be properly optimized.  It is hydroscopic after all.
    A low cost upgrade of the fuel stream into a high energy fuel eliminates a lot of inconvenience.
    As I have posted before, our science is in the process of converting biomass streams into a range of chemical feed stocks to produce useful end products.  This is a huge undertaking that compares to the development of oil based products and surely more difficult.
    Everyone can see the virtue of converting cellulose to glucose (its constituent molecule) and have known this since the nineteenth century.  That is has not been done in a commercial plant as yet is a testament to the difficulty.
    Yet this bit of work is clearly making natural processes work with us and for that reason alone is refreshing.
    We still need a good substitute for high end hydrocarbon fuels at least to replace our reliance on oil products.  That alone will end the rise in CO2 emissions globally.  We certainly need it for heavy transportation of all kinds at least in a couple of decades and then likely forever after in some form or the other.
    New Process Yields High-Energy-Density, Plant-Based Transportation Fuel
    by Staff Writers

    Madison WI (SPX) Mar 01, 2010
    While biofuels such as ethanol are becoming more popular as blending agents in automobile fuels, they have limitations for use in jet fuel because of their low energy density. And, given present internal combustion engine designs, conventional biofuels cannot fully replace petroleum-derived hydrocarbons.

    A team of University of Wisconsin-Madison engineers has developed a highly efficient, environmentally friendly process that selectively converts gamma-valerolactone, a biomass derivative, into the chemical equivalent of jet fuel.
    The simple process preserves about 95 percent of the energy from the original biomass, requires little hydrogen input, and captures carbon dioxide under high pressure for future beneficial use.
    With James Dumesic, Steenbock Professor of Chemical and Biological Engineering at UW-Madison, postdoctoral researchers Jesse Bond and David Martin Alonso, and graduate students Dong Wang and Ryan West published details of the advance in the Feb. 26 edition of the journal Science.

    Much of the Dumesic group’s previous research of using cellulosic biomass for biofuels has focused on processes that convert abundant plant-based sugars into transportation fuels. However, in previously studied conversion methods, sugar molecules frequently degrade to form levulinic acid and formic acid – two products the previous methods couldn’t readily transform into high-energy liquid fuels.
    The team’s new method exploits sugar’s tendency to degrade. “Instead of trying to fight the degradation, we started with levulinic acid and formic acid and tried to see what we could do using that as a platform,” says Dumesic.

    In the presence of metal catalysts, the two acids react to form gamma-valerolactone, or GVL, which now is manufactured in small quantities as an herbal food and perfume additive. Using laboratory-scale equipment and stable, inexpensive catalysts, Dumesic’s group converts aqueous solutions of GVL into jet fuel.

    “It really is very simple,” says Bond, of the two-step catalytic process. “We can pull off these two catalytic stages, as well as the requisite separation steps, in series, with basic equipment. With very minimal processing, we can produce a pure stream of jet-fuel-range alkenes and a fairly pure stream of carbon dioxide.”
    While biofuels such as ethanol are becoming more popular as blending agents in automobile fuels, they have limitations for use in jet fuel because of their low energy density. And, given present internal combustion engine designs, conventional biofuels cannot fully replace petroleum-derived hydrocarbons.

    “The hydrocarbons produced from GVL in this new process are chemically equivalent to those used in the present infrastructure,” says Alonso. “The product we make is ready for the jet fuel application and can be added to existing hydrocarbon blends, as needed, to meet specs.”

    The biggest barrier to implementing the renewable fuel is the cost of GVL. Until now, says Dumesic, there has not been an incentive to mass-produce the compound. “The bottleneck in having the fuel ready for prime time is the availability of cost-effective GVL,” he says.

    Now that they have demonstrated the process for converting GVL to transportation fuel, Dumesic and his students are developing more efficient methods for making GVL from biomass sources such as wood, corn stover, switchgrass and others. “Once the GVL is made effectively, I think this is an excellent way to convert it to jet fuel,” he says.
  • Livermore Fusion Fine Tuned



    This is an interesting experimental rig having little to do with any hope of power production.  They are showing that they have the ability to fine tune the process to achieve the temperature regime associated with fusion.  I presume that their listed difficulties are quite solvable in the same way that they have been able to tune density.  In short, solvability is designed in.
    What is not designed in yet is a continuous production protocol.
    And a horror of horrors, the energy production protocol is a heat engine. Since this device will also produce a lot of hot neutrons, it is surely going to irradiate the hell out of the hardware.
    I sure hope that the focus fusion technology using a combination of fusing a neutron with bismuth and then fissioning into three helium works and puts this approach out of its misery.
    As said, this is a useful experimental rig that is good for some basic science.
    Scientists Overcome Obstacle to Fusion
    The world’s largest laser system has uniformly compressed and superheated a fuel capsule.
    Thursday, January 28, 2010
    One of the key outstanding questions about whether it’s possible to use lasers to ignite fusion has been answered. A huge, stadium-sized laser facility at the Lawrence Livermore National Laboratory in Livermore, CA, uniformly compressed and heated a tiny capsule to very high temperatures. The experiments confirmed a theory the scientists there had about how to control the energy from 192 high-power lasers to compress the spherical capsule evenly from all sides.

    Siegfried Glenzer, the Plasma Physics Group Leader at LLNL, says that the experiments clear  away a major hurdle on the way to igniting fusion, a self-sustaining reaction of the sort that powers the sun. He says there’s a good chance the researchers will achieve this goal by the end of the year. If they’re successful, the facility will allow scientists to study the inner workings of stars and nuclear weapons in a controlled lab setting. It could also lead to a new type of power plant that runs on abundant hydrogen isotopes.

    Igniting fusion requires extremely high temperatures and pressures, achieved by applied energy evenly to the entire surface of a spherical fuel capsule. To do this, the researchers plan to put the sphere–which measures a couple of millimeters across, inside a small gold can called a hohlraum. The lasers would enter the can from the ends and hit its interior walls. Each of the 192 lasers would come in at a different angle. When the lasers collide with the walls of the hohlraum, they produce X-rays which are supposed to bath the sphere uniformly.

    But the researchers knew that the energy likely wouldn’t be distributed perfectly. To correct for this, they proposed the following solution:

    As the lasers enter the hohlraum, they interact with each other, producing an interference pattern, which in turn creates a plasma with regularly spaced dense areas alternating with less dense areas. This produces a sort of “grating” which acts as a prism. This prism that diffracts different colors of light to different degrees. The researchers hypothesized they could fine tune the distribution of the laser energy by very slightly altering the wavelength of the laser light. The recent experiments, reported in the journal Science, confirmed that this works. After a series of laser shots, in which they gradually altered the color of the laser, they compressed the spherical capsule evenly, and were able to heat it up to 3.3 million degrees Kelvin.

    By extrapolating from these results, they scientist say they should be able to achieve fusion using the laser system at Livermore, which was officially opened last year. Glenzer says this could happen by the end of the year.

    Obstacles remain, however. To make it work, they’ll have to crank up the lasers, doubling their output compared to these initial experiments. In so doing, they’ll be trying to approximately double the amount the sphere gets compressed, which will require very precisely timed laser pulses. What’s more, so far they haven’t included the deuterium and tritium fuel in the capsule for the tests. They’ve demonstrated they can create and maintain the precise fuel layers needed in the lab, but not within the laser system, he says.

    What’s more, even if the researchers ignite fusion, it won’t be in a form useful for generating electricity. Although the reactions will be self-sustaining, the amount of fuel in each capsule will be small, and so the duration of the burn will be brief. Generating electricity will mean developing a system that can ignite many capsules each second, and then capture the heat released to produce steam to power a turbine.
  • Microsoft confirms lack of backward compatibility in Windows Phone 7

    noapps

    In a twitter Q&A session Microsoft has confirmed that Windows Phone 7 development will take place in XNA and Silverlight. XNA is already in use on the X-box platform for mini-games and is also the foundation of application development on the ZuneHD.

    Microsoft also confirmed Windows Mobile software will not run on the Windows Phone 7 platform, with Microsoft promising they  "will continue to work with our partners to deliver new devices based on Windows Mobile 6.5 and will support those products for many years to come" .

    With this move Microsoft has sadly basically condemned Windows Phone 7 series to feature phone status for at least its first 6 months to a year, due to the very likely severe dearth of applications, especially productivity ones that take quite a long time to develop.  At the same time, despite Microsoft’s promises, we can also expect development on Windows Mobile to more or less cease also.

    It seems the time in the desert has just started.

    Do our readers think Microsoft is acting wisely? Let us know below.

  • Cyberwar Or Moral Panic? Beware Of Ex-Politicians Screaming About Cyberthreats

    For years and years we’ve been hearing about the supposed threats of “cyberwar” and “cyberterrosism.” For nearly a decade we’ve questioned whether this was all hype, and the story hasn’t changed. Sure, there are hackers and those who look to break into systems, but the real risks and overall threats still seem fairly minimal. But that’s not enough for some people. Wired’s Ryan Singel has a long, but excellent look at how former director of national intelligence (now consultant) Michael McConnell appears to be trying to build up a giant moral panic about this ill-defined threat, with the goal of basically ripping out the guts of today’s internet to recreate it with almost no privacy at all. He recently claimed:


    We need to re-engineer the Internet to make attribution, geo-location, intelligence analysis and impact assessment — who did it, from where, why and what was the result — more manageable

    In other words, we need to be able to spy on everyone. To build up this moral panic, McConnell isn’t even just getting the press to write articles for him — he’s doing it himself. The Washington Post recently gave him op-ed space to ridiculously claim that the recent hack on Google showed we’re “losing the cyberwar.” Yet, as Singel points out, that was entirely different. It wasn’t warfare, it was espionage. McConnell also played up some bogus threats, such as some old viruses and botnets that are hardly part of some dangerous “cyberwar.”

    Singel then goes on to connect McConnell’s efforts with various other political proposals lately — suggesting that the government is moving towards more control of the internet and more monitoring. At times, unfortunately, the piece feels like it slips a bit into conspiracy theory territory — but McConnell’s efforts certainly appear questionable. He’s pushing a bogus “threat” and he works for a company that could profit tremendously from any “response” to such a threat. That seems like a massive conflict of interest that a lot of people are ignoring.

  • Clavilux 2000: Generative Music Visualization Composition

    clavilux.jpg
    Clavilux 2000 [jonasheuer.de] is a subtle music visualization installation that represents the playing of sounds by way of a simultaneous animation that can be interpreted.

    For every note played on the keyboard, a stripe appears of which the dimensions, position and color correspond to the way the particular key was stroke. The length and vertical position of stripe is mapped unto the velocity, while the stripe’s width reflects the length of each note. By mapping the color wheel on the circle of 5ths, the colors give the viewer (and listener) an impression of the harmonic relations. Notes belonging to one specific tonality correspond to colors from one specific area of the color wheel. Therefore each key has its own color scheme and “wrong” notes stand out in contrasting colors. The more different tonalities a music piece has, the more colorful the resulting visualization will be.

    As all the stripes do not disappear, the resulting representation is able to convey insights about the composition as well as the specific performance: Which notes were played the most? Which were the loudest notes? Which range of the keys was played mostly? How harmonically constant was the music?

    Watch the visualization in action below.


  • Live Labs Pivot: A Massive Interactive Zoom on Data (TED Talk)

    pivot.jpg
    Viewing information and data in this way, is a lot like swimming in a living information infographic.” During his very impressive TED talk, Gary Flake, Technical Fellow at Microsoft, demos the novel and still experimental Pivot [getpivot.com] technology. Pivot is a completely new way to browse and arrange massive amounts of images and data online. Built on the Seadragon zooming technology, it enables spectacular zooming in and out of web databases, and the discovery of patterns and links invisible in standard web browsing.

    Right now, in this world, we think about data as being this curse, we talk about the curse of information overload, drowning in data. What if we can turn that upside down, so that instead of navigating from one thing to the next, we get used to the habit of being able to go from many things to many things and then being able to see the patterns that were otherwise hidden.

    Watch the video of the talk below.

    What will it enable in the world of data visualization that was not possible before?


  • Z-Gun™ Magnetron Sputter Source

    Our newly developed Rotating Magnetron Guns (Z-Guns™) have been specifically engineered for the demanding requirements of data storage media producers. Integration with a new system or retrofitting an existing system is facilitated by Dexter’s new design and control interface.

    Our Z-Guns and magnet arrays can be optimized to produce a cathode capable of sputtering highly permeable materials such as Nickel, Iron and Cobalt; or, coupled to modules specifically designed for a given target material or customer application.

    The magnetic films used in perpendicular media require a relatively thick soft underlayer (SUL) not found in films of longitudinal media. In order to minimize target changeover for this layer, our Z-Guns allow the end users and OEMs to run thicker targets up to and over 12mm depending on the SUL target material.

    Our gun offers the industry’s highest sputter efficiency because our source to substrate distance has been optimized while maintaining deposition uniformity.

    Our guns can also produce radial anisotropic magnetic films. The mechanics of our Z-Guns provide a more robust design that can withstand the strong magnetic attractive forces created between the magnetic target and the high flux density magnetron while providing the flexibility for quick repairs and magnetic field adjustments. Our Z-Gun meets these requirements.

    In most applications, customers are trying to maximize target utilization and achieve optimum uniformity. Our gun is capable of achieving both, along with radial magnetic anisotropy and zero re-deposition.

    The Z-Gun sputtering sources feature a unique “magnet array’ which is completely isolated from the cooling water to eliminate magnet deterioration and subsequent degradation of source performance. This design permits easy access to the internal magnetic component arrangement thus allowing quick changes to the magnet array.

    The Z-Gun sputtering sources are sleek and compact.

    They feature programmable, high torque, DC motor drives along with a touch screen user interface. Rotational speed, phase shifting between coincident magnetron pairs, and z-position can be programmed for specific targets and processes.

    The program can maintain fixed set of variable routines or allow dynamic changes in the routines to optimize performance as target erosion changes critical system parameters. Magnetron synchronization is another feature that can be programmed by the user.

    The evolution of this product has resulted in the most service friendly product of its kind on the market, thereby providing our customers with maximized ‘up time’ and frustration free maintenance.
