  1. direct link? on Study Proves Having Fat Friends Makes You Fat · · Score: 1

    I couldn't find the direct causal link mentioned above in the article.. just that they couldn't figure out what was the link.. and it doesn't seem that hard to dream up some explanations..

    example: You work at a company, your friends work at the same company, company goes bankrupt, you all grow fatter at the same time.
    exampl2: You go to college, your friends are of your age, and also go to college, you all grow a beer belly.

    But it is bloody hard to to avoid the word 'evolution' if you're studying the 'within-host' and 'within-population' evolution of HIV. Maybe there are scientists among slashdot that actually have experience with editors asking them to not mention the word evolution.. (my first paper, so no experience here yet). I'll look forward to reading the comments :).

    Depends on your simulation. I'm pairing 1000 hosts with 10 virus quasispecies for a few million years, and objects seem to be just the way to program that.

  4. Re:We need more truth, less humanistic claptrap! on Creationism Museum To Open Next Summer · · Score: 2, Insightful

    As far as I understand, suicide bombers (palestinian and otherwise) are often recruited from families that are either in debt, and get a way to clear their debt, or are just young men brainwashed enough with religion to actually go out there and explode themselves. Basically, they're manipulated to further the goals of some organization and again with the use of religion. So I wouldn't look at the actual purpetrators, but more at the masterminds behind it to discover what drives these people. My guess still is the good ole horseman of fear, hatred, power and riches.

    Atheism, not religion, is the real force behind the mass murders of history
    I always thought it were power-hungry / big-ego bastards that killed, in the name of [insert favorite excuse here]. I'm quite sure that most of these bastards had/have a religion, so while I agree with your point that religion has been used and abused to murder in its name, that does not mean that the opposite of religion (atheism) is the true cause, nor does the above rant gives any argument why and how atheism leads to mass murder.

    Hideous mess is your meaning, not a fact. I was very very pleased with the LOTR.. so while for you the article might be good news, for me it is bad. I'd have loved Peter Jackson to make the hobbit. I wonder if with 'accounting issue' they mean http://en.wikipedia.org/wiki/Hollywood_accounting Whenever someone brings up the argument that we're stealing from artists when we dload a movie or music, and we kill all music, I hum a little hollywood-accouting tune in my head.

  7. Re:Blizzard too huh? on Blizzard Lawyers Visit Creator of WoW Glider · · Score: 1

    So let me get this straight:

    A. They make the game so damn boring and tedious that people resort to using a program to play the game for them.
    B. And then on top of that, they can't even code their software good enough to keep the majority of people from cheating.


    A: No. Goldfarmers resort to using a program to make money for them, and sell that money. Very few players do.

    B: The majority of people doesn't cheat.
    ----------

    I've no facts or figures, just in game experience: I've only once seen a bot that was also a regular player. Usually bots are always bots, and players are always players. Bots are used by IGE and other web companies to make real-life money. As long as there are people buying the gold, this negatively affects people that enjoy playing the game (economy-wise). The game isn't boring if you play it normally. If you play it all-the-time.. learn to stop things when they are becoming boring, and switch to doing something else :)

    Had to make the same choice a bit earlier as well (what scripting language to learn: perl, python, ruby) (briefly looked at scheme / lisp too).

  10. Actually on MyDoom Seeks to Destroy Antivirus Firms · · Score: 1

    The silly thing about HIV (AIDS) isn't that it's killing off your immune system.. AFAIUnderstand, healthy CD4+ T-helper cells (the type of immune cells you're losing when you're HIV+) that come in contact with an infected CD4+ T-helper cell tend to self-destruct.

    If we're going to try and translate that to computerviruses and a computers' immune system.. Oh well, let's try.

    ---
    Virus enters computer. Establishes infection. It shuts down a few processes, including some of the popular virus scanners, and alters a host file to mess with updates. New tools to remove the virus are developed on the web, and the virus gets update from a server on sealand which processes now to kill. - arms race. Whoever gets the update first, wins.

    ---
    An HIV analogy would assume a host of virus scanners slowly being deminished on your computer, and mainly because virus scanners infected with the virus cause other virus scanners to crash. We're not there yet :)

    I have a few friends that have 2-3 virus scanners on their pc, but that never seemed a very good solution to me.

  11. Re:What about.. on Unexplained Leap In CO2 Levels · · Score: 2
    Ya. I think it is funny that a bunch of folks who can't give me a local weather forcast for more than 3 days into the future that is in any way accurate can tell me about weather predictions for the next 100 years.
    Those guys aren't giving you local weather predictions for 2104. "Sunny in the morning, but a bit of rain later in the day". It's a whole different scale on which that is modeled.

    Similar example. People can't predict earthquakes, but I'm betting that a continental-drift picture for the next 10.0000 years will be very accurate.

    If you let your continents drift, you can be sure that earthquakes occur. Exactly when or where is rather irrelevant for the drift-model.

  13. Re:What about.. on Unexplained Leap In CO2 Levels · · Score: 4, Insightful

    Well, chances are that the model is flawed. I'm a theoretical biologist, so modelling biological processes is what I do (HIV evolution for me at the moment), and as the co2 level is in part a biological problem, I can spew some incoherent thoughts about it, claiming it's the opinion of an expert. ;)

    Just because there's no way for us to give a good estimate of the impact of our actions on the earth, doesn't mean that we need to consider those actions more carefully then we are now. We're only just emerging from a few centuries in which we just exploited everything, assuming that we wouldn't run out of resources.

    If we slipped past a threshold and we're in a runaway heating, then life as you know it ends soon. It might be because of human actions, or it might not be, but that's not important. We don't want the earth to end up as either Mars or Venus, and we'll have to take what actions seem neccesary (and that doesn't include saving the economy :P).

    Too bad it isn't my turn to rule the earth.

  17. (Local) - yep, sailing on Wi-Fi Warsailing In The Netherlands · · Score: 2, Informative

    I was born there :P. Somewhat surprised to find a map showing my sleepy homevillage. Anyway, with small boats (16^2 meter sails) you can perfectly well sail there. Larger boats will have to wait for the bridges to open up, so that'd be somewhat awkward sailing, except on the upper bit of the map (called Kaag), which is wide open, and a popular sailing place.

    Enjoy.
