  1. Go where your expertise is on Ask Slashdot: One Framework To Rule Them All? · · Score: 4, Insightful

    If people in your group already love RoR, it's best to go with their expertise. Technically, there isn't enough difference to make it matter.
    Backends are virtually always in a different language than frontends (not that that's a good thing, but it shouldn't worry you too much).

  2. Re:Wrong problem on Genome Researchers Have Too Much Data · · Score: 2

    To be clear, the problem is this. The sequencing (cheap now) produces a lot of strips of a few DNA elements. They are overlapping, and its unknown from which position they are from.

    So the difficulty is to arrange those strips to reproduce the original DNA sequence. It is a NP-hard problem, no wonder Moore's law doesn't outrun that!

  3. Re:And still... on Chrome Becoming World's Second Most Popular Web Browser · · Score: 1

    Its just not true that Firefox is losing "market share" (browser users). Just look at the data, Firefox isn't gaining or losing.
    I can imagine that the inflow of Firefox users from IE is similar to what it ever was, and that Firefox users are going to Chrome. Surely, there are also IE to Chrome converts, but may be a smaller fraction. It'd be interesting to see a flow analysis like they do after elections.

  4. Re:And still... on Chrome Becoming World's Second Most Popular Web Browser · · Score: 5, Insightful

    I think Mozilla is very happy with the stats, because the real news is that the IE usage went down to almost ~50%, and we have today a diversity of browser (engines). Diversity ensures that we don't drive into a dead end, and Mozilla paved the way for alternative browsers, pushing websites away from IE-only design, and making the new technologies we have today possible (CSS, everything beyond HTML4, fast JS) -- although we have to give Microsoft credit for inventing Ajax.

  5. Re:Your assessment is quite incorrect, actually on Hacker Tries To Land IT Job At Marriott Via Extortion · · Score: 2

    We all know technology works that way, but we doubt the law works that way. Bring some information to the table that you don't have to be physically in a country to break that countries laws. International law excluded, as it doesn't cover hacking (as far as I am aware of it).

  6. Re:Two things on The Science of Humor · · Score: 1

    The "two goldfish in a tank"-joke doesn't have a loser. I'd be really interested in a list of animals where humor has been observed, and how that manifests (or can be detected). To be genuine, it mustn't be something trained on (like most of dogs "humanoid" behaviour).

  7. Re:Outside the metric's domain; I'd already gradua on 4.74 Degrees of Separation on Facebook · · Score: 1

    You also don't know anyone with a Facebook account, and no one you know knows anyone with a Facebook account, and so on?

    The metric covers only Facebook, just as the Erdo"s metric covers only coauthorship of articles in scholarly journals and the Bacon metric covers only publicly exhibited feature films.

    There should be a considerable bias in the estimate of an average degree of separation of 4.74. The people not on facebook are more loosely connected than those on facebook, so the average would increase. Also, the average used to be higher (in previous estimates on facebook), suggesting that the networking of existing people on facebook gets denser over time (you add/get to know friends of friends), while the overall number of people on facebook doesn't grow as fast anymore as it used to.

  8. Re:Dark matter or antimatter? on Cosmic Antimatter Excess Confirmed · · Score: 1

    The above paragraph, if true, would make the universe a very explode-y place.

    I'd say it is an "explodey" place. Hell, there's a hydrogen bomb only eight light seconds away, and it's been exploding for over four billion years. Almost every twinkle in the night sky is a incredibly huge fusion explosion.

    The street is an "explodey" [what is that word!?] place. There is a car 1 meter away, and it has been exploding oil for an hour now. Almost every noise you hear in a street is a powerful explosion.

    There is no reason to make it sound so scary. It is an ensemble of continuous, small, explosions that amass to a continuous energy output (not "explodey").

  10. Re:Sometimes they get it right on EU Approves Unified Full Body Scanner Regulations · · Score: 1

    In between ceizing all the power from the individual member states, and destroying all our economies by pumping the money into the bottomless pits of high interest, sometimes they do something right. Thanks EU :-)

    Shall we also allow everyone to bring a bottle of water onto the airplane? There's a lot of money to be saved by reducing the silly safety measures.

    Your statement doesn't make sense. The EU is nothing but the member states, and its bodies are just representatives from countries. So it is the member states doing the things you say: "The member states ceizing all the power from the individual member states, and the member states destroying all our economies by pumping the money into the bottomless pits of high interest".

    If not all the participating countries would agree and sign a agreement for each action taken, nothing would happen!

    It is not the White House saying it is addictive, they are saying "According to scientists at the National Institutes of Health- the world's largest source of drug abuse research - marijuana use is associated with addiction, respiratory disease, and cognitive impairment."
    On the page of the NIH, http://www.nida.nih.gov/tib/marijuana.html you will find

    Marijuana and Addiction

    Long-term marijuana use can lead to addiction; that is, people use the drug compulsively even though it interferes with family, school, work, and recreational activities. According to NSDUH, in 2010 of the estimated 7.1 million Americans classified with dependence on or abuse of illicit drugs, nearly 4.5 million were dependent on or abused marijuana. Research has shown that approximately 9% of people who use marijuana may become dependent. The risk of addiction goes up to about 1 in 6 among those who start using as adolescents, and 25-50% of daily users. In 2009, 18% of people entering drug abuse treatment programs reported marijuana as their primary drug of abuse (70% of those aged 12-14; and 72% of those 15-17), representing more than 350,000 admissions (TEDS, 2009). Along with craving, withdrawal symptoms such as irritability, sleeping problems, and anxiety can make it difficult for long-term marijuana smokers to quit.

    Would it be possible to use a balloon to get to 30+km, then turn it around and use it as a rocket platform, launching a rocket to, say, the moon? It wouldn't have to be a very powerful rocket (and thus steerable like in the game Asteroids).
    I'm probably being naive here...

  17. Re:Hindsight on UN Bigwig: The Web Should Have Been Patented and Licensed · · Score: 0, Flamebait

    Slashdot groupthink at its best in this thread. The tone are personal attacks. "Patents are evil! Burn pro-patent people! UN is stupid!". How sad. Nobody saw the video, or tried to understand the argument he was trying to make.

    He made the point that IP are useful because patents document an invention, information otherwise lost. He brings the example of Violin vs. Saxophone.
    I think his intention is correct, but should be solved by open standards as documentation, not patents.

    He mentions there are many options in IP (I guess beyond patents [/. groupthink: bad] and copyright [/. groupthink: good]), but he doesn't explore what they are, or how they would have beneficial (to whom?) in case of the WWW.

    I think he made the mistake of taking an example from the software/standards world. If he had taken an example of hardware, it would have been a good argument: It is beneficial if what happens behind the doors of e.g. car factories is patented -- i.e. brought to the open for improvements -- that way it is documented, can be improved upon, yet protected from IP theft.

    The tone of the video (jump to 0:49:50) is also different from what it is portrayed as. His "talk" was a tiny side-note on a discussion/presentation. Does his comment mean the whole "The Global Innovation Index 2011" is useless? I think there are better arguments to be made, for instance: Does history show that "innovation programmes" from top-level effectively stimulate innovation, or is it just random successes by individuals? What are really the important factors (not for economic success, but for beneficial contributions)?

  23. Re:Very depressing! on 2011 Nobel Prize In Physics · · Score: 1

    Would it be less depressing to you if all ended in a Big Crunch? Why do we find a static universe pleasing? No birth without death.

    Galaxies don't expand, so two planets wouldn't work as a way to harness dark energy. But the idea is that every cube of space, when you take out all the mass, still has some energy. Perhaps in form of tension or a pressure. So you wouldn't need to go far. But it is incredibly little. Although I should emphasize we don't know what it is yet, so we wouldn't even know how to start harnessing it.

    Maybe some Italian article would be useful to me even though I'm not Italian nor speak Italian (there are translators). Why does everyone else have to suffer?
