  1. Re:Well clearly on A Week After Apple's Fix, Flashback Still Infects Half a Million Macs · · Score: 2

    What the hell is this rebooting you speak of? I thought Macs were Unix-based? You only reboot when you install new hardware or when you do a kernel update. (I should add that on a random-joe-system, kernel updates should be pretty infrequent since they don't need bleeding edge kernels). This sounds not much better than windows, IMHO.

    Also, I wonder how Apple, the paragon of UI design, has never been able to implement a good window manager? It makes my eyes bleed every time I try to place Firefox and a terminal window side-by-side on a friends machine.

    There are problems with MOND indeed. Take a look at the predicted power spectrum of matter: http://i.imgur.com/Ouwin.png

    Care to explain what vim in laptop-mode is? (Genuinely interested)

    As an aside, I once used vim to take notes in LaTeX from a quantum field theory lecture. Even with vim-latex, shorthand and lots of custom macros, it needed about 5 mins of fixing afterwards to make it compile, and I have never worked so hard at typing in my entire life. (It was a bet against one of my classmates that it would be impossible to take "live" notes in LaTeX. I won.) Moral of the story: if equations are involved, you need a stylus, or just use pencil and paper.

    I never said there was a global ban, just a sharp reduction in use. Wikipedia supports this, and adds that malaria infections were reduced by 60% in Ecuador when the country started increasing DDT usage again. Also, I said tens of thousands, not millions. As the WHO points out in its 2008 report, there are 800 000 deaths yearly from malaria, so a 5-10% increase is hardly unlikely.

    Look, I'm not some anti-global-warming-nut, I'm just pointing out an unintended negative consequence of environmentalism.

    There are even worse examples than that. "Silent Spring" caused huge reduction in the use of DDT as a pesticide, as it reported environmental consequences along with some studies linking it to cancer. Of those studies, one had design errors and the others people haven't been able to reproduce. Meanwhile, the reduced use of DDT in Africa and South America caused a huge increase in deaths from malaria, projected to be in the tens of thousands. Countries where malaria is a problem are now starting to use DDT again, and are seing malaria infection rates drop dramatically. Meanwhile, Americans are happy because the population of their national bird has increased.

  9. Re:Great for manga on LG Begins Mass Production of First Flexible E-ink Displays · · Score: 1

    Why can't it have wifi? It's much easier than dealing with a new card for every new magazine. I have newspaper subscriptions on my Kindle that automagically sync over wifi every morning, and I still get 3 weeks on a single charge. Mind you, I turn on wifi, sync, and then turn off wifi. This takes about as much time as making my cup of coffee.

    Also, IMO, sturdiness is not the problem with current e-readers. My Kindle (in a cover) has survived 1.5 years of being tossed around in my backpack with books, water bottles, etc. The problem is that you want a large screen to read on, but a small device to put in your bag. That is the issue these screens may solve.

  10. Re:Is there any volunteer? on Particle-Wave Duality Demonstrated With Largest Molecules Yet · · Score: 5, Informative

    Alright, let me clarify what I meant. In fusion, the main factors in determining the reaction speed is the energy and the density. While the energy is comparable in the sun and a hydrogen bomb, the density is 2 orders of magnitude higher in a hydrogen bomb than at the sun's core. The tunneling probability is exponentially sensitive to the density; so sensitive that a third of the way out from the sun's core, fusion can no longer happen. This means that those 2 orders of magnitude are translated into 20 orders of magnitude slower explosion. At that point, I wouldn't call it an explosion.

    Just to highlight this point: the power production per volume at the sun's core is 280 W/m^3. This is less than for a human being, it's roughly the same power as a crocodile produces per volume.

    TL;DR: You're saying that the smoldering pile of flour on my kitchen bench is exactly like a dust explosion. I beg to differ.

  11. Re:Is there any volunteer? on Particle-Wave Duality Demonstrated With Largest Molecules Yet · · Score: 5, Informative

    Scientists are currently trying, albeit with somewhat smaller objects than a person. What you should understand is that the tunneling probability is exponentially damped in both the width of the barrier and the size of the object.

    Already for a hydrogen nucleus tunneling through the (electrostatic) potential barrier presented by another hydrogen nucleus, the probability is around 10^-30 (if memory serves correctly). This fact is what keeps the sun burning for billions of years, and not exploding like a hydrogen bomb in a split second, since it limits the rate of fusion processes in the sun.

If WP7 lacks such apps, then either WP7 has few developers, or it is a pain in the **s developing a WP7 app that makes the phone interface with something else. Or knowing MS, it could be both of the above.

    If Linux had the market share, there would need to be a way to install programs and games from other than the distro repos.
