  1. Re:Yup, it's the same Chomsky on John W. Backus Dies at 82; Developed FORTRAN · · Score: 2, Interesting

    Linguists, in general, seem to have an interesting way of looking at the world. Chomsky has a way of looking at a political situation in a unique way and formulating an opinion that's not widely held (in fact, one that typically annoys all extremes of the political spectrum). Right or wrong, it's an interesting process.

    Larry Wall has a similar outlook (though his politics likely diverge heavily from Chomsky, I dunno). He has that linguist's way of looking at theoretically opposing points of view and rationalizing them against each other in a very logical way. It's a kind of fun process to watch, and it makes me wish I had that knack.

    Back to Backus: he will be missed. His work in CS was truly ground-breaking, even (especially) where it simply extended the work of others. FORTRAN has a legacy all its own, and the fact that the scientific community still continues to use it to this day is testimony to its power and utility, even if much of it is dated today.

    Even those mice you mentioned (hyperphagic) actually consumed far more than the others. The problem was they had lost their ability to know when to stop eating. Actually, it's been demonstrated fairly conclusively that there are animals (including mice and humans) who never had a fully developed ability to know when to stop eating in the first place. This is part of why it's so hard for people to understand the problem. So many people just assume that everyone knows when they've eaten enough, and they can't imagine the difficulty that arises from trying to stop eating when your body tells you that you're still hungry.

    That said, of course, you're right to an extent. The problem compounds itself as your insulin production adapts to your over-eating, and eventually becomes far, far worse, potentially even leading to diabetes when your pancreas just gives up entirely.

    Body fat isn't magic. Neither is diabetes or heart disease, but while we know that risks for both can be dramatically altered via diet and lifestyle, we also know that the single largest factor in both is genetics. When it comes to obesity, however, we have a blind spot. I suspect that that's genetic as well.

    It comes from food you eat. If you are exercising more and still have more weight, it means you are eating too much. People need to stop looking for excuses. Most of us aren't looking for excuses, but rather for the mechanisms that drive one person to become obese while another remains thin. We know that in mice there are a number of disorders which can cause one mouse out of a population to gain weight on the same diet as the others. We also know that there are disorders in the opposite direction: the need to consume far more in order to support a minimal level of fat reserves.

    These aren't mysteries, but there's a strong social stigma that tells us that those who are obese just aren't "trying". Well, I can tell you from personal experience that, even motivated by health problems, it was a HUGE effort for me to go from morbidly obese down to merely substantially overweight, and it's even harder keeping it off in the long term. I walk a minimum of 10 miles per week, and when the weather is good I hike, swim, and I even took up running until shin splints made it too painful to sustain. Yes, I think there's a significant genetic hurdle in my way, and no I'm not looking for something to "blame" or for an "excuse" to cry over. I'm just dead-sure that people with more median physiological makeups have absolutely no idea how much work it is for someone like myself to loose weight, nor how exponential that curve is with respect to how much weight I want to loose.

I'm not in 100% agreement with everything you said, but this is what we should be talking about. Instead of inventing scare-tactic scenarios where millions die, we should be focusing on the most likely outcomes within two or three sigma, and talking about how they stack up against other problems we face. Then we can discuss solutions that make sense.

    Pot/Kettle

    Other than your attempts to divert the issue away from one of the most amazing statements ever to be made in the political world, I'm not sure what your point there is (BTW: I'll note that I haven't told you my party affiliation... just for fun, I'm going to continue to not do so, as I love watching people guess).

    As an ofttimes Republican voter I was:

    * Upset when a thorough study of the 2000 Florida results (by mostly liberal mainstream media) concluded that Bush had indeed won the state, but long after that history has been re-written to only focus on headlines from 24 hours after the election.

    This is unrelated to my point, but it so happens it's wrong. In reality a number of news outlets worked together to determine which of the statistical methods that various parties were pushing for made sense, given the situation. The conclusion was not particularly aimed at a "who won" sort of result, but the findings did indicate that Al Gore's chosen method of recount would not have made a substantial difference in the outcome, while a state-wide recount most likely would have resulted in the opposite result.[1]

    * Upset that in the 2004 election cycle, Democrats AGAIN cried foul in districts where lazy, incompetent election officials spent taxpayers money hand over fist too buy this junky hardware and software rather than do realistic requirements analysis, and particularly upset that while these changes took place (pre 2004) these same left wing complainers said NOTHING, waiting instead for the results that they didn't like.

    This is not fair. I watched as plenty of "left wing complainers" screamed bloody murder in the non-mainstream press, but the mainstream press didn't want to touch the story because it was too "technical." Once the election was on... then it was news. Either way, the fault does not lie with the "complainers", but with those that were producing the bad systems and selling them to states that were hard-pressed to meet ill-interpreted new regulations.

    * Post 2004 I engaged in numerous debates with individuals who swore they were not complaining about the 2004 results, but were indeed interested in the issue. Again, these people grew silent as distance from the 2004 election increased. As I would bring up newly discovered issues with this Windoze based software (and hardware) they would thank me politely for reminding them and then go right back to Bush bashing, continuing to ignore the very REAL bipartisan problems that were being ignored by the mainstream media.

    Many of us have given up, and it's nice to see in this article that Diebold is finally deciding that they don't want to be in that business.

    * While you say the results of 2006 were "overwhelming", in fact in many local elections the margin of victory, particularly for newly elected democrats were a dozen votes, and for state level offices a few hundred. Almost NONE of these votes were contested, even in cases where the Republican candidate had only to request a recount.

On the budgetary side, that installation wants to know how much replacement cost to expect per annum. On the admin side, that installation wants to be prepared with an appropriate number of redundant systems, and wants to be able to assert a failure probability for key systems. That is, if you have a raid array with 5 disks and one spare, then you want to know the probability that three disks will fail on it in the, let's say, 6 hour worst-case window before you can replace any of them. That probability is non-zero, and must be accounted for in your computation of anticipated downtime, along with every other unlikely, but possible event that you can account for.
