  1. Wrong study techniques on Ask Slashdot: Can an Old Programmer Learn New Tricks? · · Score: 1

    You are clearly a reasonably intelligent and capable person, and that doesn't go away with age. It does become harder to memorize things as you age. (Remember when you were 6 and could recite whole episodes of cartoons that you had only seen two or three times? That's not happening again.)

    Whenever you spend time studying and fail to learn it's always because of one of two problems: lack of smarts, or the wrong studying techniques / studying environment. In your case it must be the latter. Did you go to college and if so did you study math and other technical subjects or did you study fussy things like English? If you've never learned how to learn then the place to start is to Google "studying techniques" and become an expert at that.

    For example there are many technical concepts that are best learnt by drawing charts and diagrams on sheets of papers, crumbling them up and throwing them away and redrawing the charts and diagrams on new sheets of papers until you get something that corresponds to what the texbook is telling you. Also, just copying diagrams and other drawings straight out of textbooks can help. It's a cheap trick, but it works. There are lots of these "cheap tricks". Learn them.

    And considering that arcs (as presented) do not have error brackets on them is a dead giveaway that qualifications of people who did the calculations are highly suspect.

    you can get aviation fuel most anywhere, and just use kerosene if you don't care much about long term

    But you first have to land somewhere. My point is that if you think you have longer range than you actually have you're prone to end up running out of fuel before you reach your intended destination. No big deal if you're in a car. Very, very bad if you're in a plane over the ocean.

    Landing a 777 takes a significant airstrip. Really significant. Once there, it's not simply a taxi to some secluded spot. If your scenario is true, the plane should be visible by satellite.

    Well, maybe the highjacker thought that the plane had longer range than it actually had. In that scenario we're looking at painstakingly scanning the ocean with sonar to find the wreckage.

    Never going to happen. We don't even have accurate charts for the depth of most of the ocean -- it's just extrapolated from gravity measurements from satellites.

    The petroleum industry has some pretty awesome equipment that they use to look for oil and gas. They also maps of much of the sea floor that are way beyond anything that's publicly available. You can certainly find the wreckage given enough time and funding, especially if you can narrow the search area down based on the known facts of the disappearance and create a probability distribution across that search area so that you can search the most probable areas first.

    But the plane would only have had enough fuel to fly to Beijing (plus some additional safety margin).

    One possibility is that a highjacker made the same mistake that you did and ran out of fuel over the ocean.

    Well, a person who takes hundreds of people with them in their suicide probably has things going on in their heads that we'd find difficult to understand. Suicidal people sometimes commit suicide in ways that are planned and designed to look like accidents.

    Of course we don't know that it was suicide. It could just have been an unusually unreasonable highjacker who didn't understand that the 777-200 had shorter range than for example Wikipedia lists because it wasn't fully fueled for the relatively short flight to Beijing.

  8. Re:Russia is evil again. on Russia Blocks Internet Sites of Putin Critics · · Score: 1

    We can hope that Putin will be satisfied with Crimea, but it looks like Moldova is next on his list. One can hope that that will be all that he takes and that he wouldn't for example risk invading Lithuania, a NATO country. But on the other hand, what could be a greater victory for Putin and his dream of breaking the west's dominance than invading a NATO country Crimea-style, without a shot fired? It would shatter the idea that NATO is a strong and relevant player in one fell swoop.

    The thing that is both hopeful and frightening depending on how you look at it is that Russia's neighbors and Russia are both dependent on the trade of Russian gas. The neighbors for their survival and Russia for it's trade balance. Whatever he does, Putin is probably not going to risk a shooting war that could destroy gas pipelines and ruin trade relationships.

  9. Re:Russia is evil again. on Russia Blocks Internet Sites of Putin Critics · · Score: 2

    It's nice that we've had 25 year break from facing global thermonuclear war, but Russia is an expansionist aggressive nation again. Mutually assured destruction may not work this time if Putin would rather die and take the rest of the world out with him rather then relinquish power.

    I suspect you're quite wrong. Men like Putin (megalomaniac psychopaths) adore and respect military strength in others and, as with all psychopaths, they love themselves far to much to risk dying. If Obama had responded by moving intermediate range nuclear missiles into Poland and the Baltic countries thus enabling a faster first strike capability, Putin might have been angry at first, but the US would have won his respect in the long run.

    If history is anything to go by Putin is going to keep doing land grabs until someone with a good arsenal of nukes agrees to play the brinksmanship game with him.

    Lots of countries have laws that prohibit carriers from differentiating the pricing based on phone model or have carriers who aren't crooked enough that they'd want to do something like that, so the data plan for a smartphone is not necessarily going to be more expensive if you already have a data plan for your feature phone.

    A minimal 100MB data plan is probably only a dollar or two in many low income countries, so it's no big deal.

  14. Re:Surviving off the GPL on Interview: Ask Richard Stallman What You Will · · Score: 1

    This seems to be THE main question that people that are first introduced to free software ask. If Stallman manages to provide a compelling answer to this, it absolutely HAS to be published on GNU.org as one of the primary articles, it would make it much easier to convince people to accept free software ideals.

    I've heard him answer the question in the Q&A section of a couple of his talks on Youtube. I don't want to speak for him, but let's just say that I think his answers so far to that question, if they were more widely know, would not make it easier to convince most people who work in the software industry. That doesn't say anything about whether or not he is right or wrong in principle it just says that he probably will never have things his way.

    I guess maybe Stallman is playing the "take the idealistic extreme position, leave the pragmatic compromising to others" game.

    It will probably be trivial to port apps as long as they don't use Google Play Services or other Google stuff. It's also pretty easy to mirror a lot of Google Play content on your own app store.

    The way this is probably going to work for a lot of apps is that Nokia will have an automatic script that downloads runnables from Google Play (it's questionable if this is allowed by Google's terms of use, but they haven't gone after anyone for doing it), installs them on their hardware, does some automatic testing to see which apps crash and which don't. For the ones that don't the script will email the developer offering to upload the runnable to Nokia's app store. All the developer has to do is click a link, or answer "yes" to the email.

    The important thing to remember is that statements about the difference about men and women should not automatically be taken to say anything about the underlying mechanisms. In case of hair length it's surely a cultural thing, probably originating when men had to cut their hair short in order to not have accidents when they worked in factories in the 1850-1950 industrial age in the west. It is perhaps not a coincidence that short haircuts on women became fashionable after WW1 when many women had worked in factories.

    Nonsense. Men don't have to act a certain way, and neither do women.

    That's true, of course. Men could all grow their hair long and women could all cut theirs short, but in reality it's the other way around in many cultures.

    Studies about differences between men and women are just that - studies about differences. They usually don't find the mechanisms that cause the differences.

Assuming they can get those 450 million (and counting) to go through the trouble of entering a payment method they're going to be making hundreds of millions of dollars without having to hire lots of people to device clever snooping and ad-targeting schemes.

    How come factory farms are the cheapest way of producing meat? To answer my own question: cheap energy. Petroleum is still cheap enough that we can turn it into tons of artificial fertilizer, spread that over enormous fields of maize and soy, feed the plants to animals and then eat the animals and their milk and eggs as if there was an endless supply of them.

    What does this mean exactly? Does it deny that AIDS exists? Does it deny that HIV leads to AIDS? Does it deny that non-gay people or non-Africans can get AIDS? Does it say it's all a government conspiracy and really caused by chemtrails?

    One way or another, it doesn't sound like something that warrants debunking, but then again, I'm often surprised at just how stupid people can be.

    It's not possible to find a single party line, but these are the most common beliefs AFAIK:

    AIDS is caused by chemicals, big pharma, the government, the Bilderberg group, the Illuminati, space lizards, etc.
    HIV either does not exist, or exists and is harmless, or exists and is harmful and created by evil men in their evil laboratories but does not cause AIDS.
    Chemtrails could totally cause AIDS, but more evidence is needed. In other words some dude on the internet needs to write a speculative blogpost that claims that chemtrails cause AIDS before we can say with certainty that it does.

    If you think this is harmless stupidity, think again. IIRC there is at least one case of an HIV positive mother who refused to test her child. The child later died in an illness with symptoms like those of someone who has AIDS. The mother also died, naturally.
