  1. Re:Is it MIT that's gender biased.... on MIT Names First Female President · · Score: 0
    This should prove to our readers (in response to some of the above posts) that there indeed is some serious gender bias out there. How depressing.

    How is it gender biased to ask that question? (Though I would have phrased it as "or is it that women don't have the same aptitude for math, science and engineering on average?)

    There are clearly (on average) physiological and mental differences between men and women, although more research needs to be done to quantify those differences. It is also hard to say how much social conditioning and learning have to do with these issues (nature versus nurture). I know some studies have shown that men have a better grasp of 3D spatial relationships on average, for instance.

    It may (or may not) be that advocating "equal numbers" of female mathematicians, scientists and engineers is on par with advocating equal numbers of female NFL players, female championship heavyweight boxers (WBF etc.) or female ditchdiggers.

    All that said, I certainly welcome and encourage those women that have an aptitude and desire for math and science oriented pursuits. I just don't think it should be forced on women in general in some misguided pursuit of "equality".

    I hate political correctness in general, and in particular that which refuses to admit there are real differences between the sexes - because there are. Billions of years of evolution have made it so. We should try to better understand those differences (viva la difference!), rather than burying our heads in the sand and pretending futilely they don't exist.

    I'm sure this will get modded to oblivion, but at least try to consider the facts of the situation rather than having a knee-jerk reaction. TIA. :-)

    I happen to like the Moller M400 design.

    It covers most of the issues you bring up with the exception of the automation issue (note the 300 MPH cruise speed at altitude). For short hops it can do 140+ MPH. It is VTOL, so there is no tough navigation issue other than collision avoidance on takeoff/landing. I'd think landing areas (parking lots) would have vertical corridors at each end, one for landing, one for taking off. Vehicles would either land in the landing zone and then taxi (hover at ground level) to their parking spot, or reverse the process to take off. Avoiding hitting people would be the biggest issue, which might call for manual control at ground level only.

    This type of vehicle would be quite suitable for short-haul, as well as long-haul, travel. It'd sure be nice reading/surfing during the trip to work...

    Remember, the way this would actually work is that small numbers of early adopters would pioneer this (air taxis according to the article). Once the initial wrinkles are worked out, it'd be ready for wider adoption. Economies of scale would set in, making them less expensive over time. At the same time, software able to handle truly large numbers of vehicles in the air simultaneously will arrive.

    Clean hydrogen or alcohol turbines will make the pollution/mileage issue moot. The M400 is supposed to get 20 MPG anyhow, which is better than many vehicles on the road today...

    I think it'll happen...it's only a matter of when. :-)

    I live in Boston. Drivers here have more than enough trouble coping with travel in two dimensions. Adding a third is a recipe for disaster.

    That's a silly attitude. The addition of a third dimension also adds a lot more room to avoid other vehicles.

    That, coupled with good automation that'll eliminate the risks of intoxication and fatigue, should make flying vehicles much safer than land vehicles. Also, think how much will be saved (eventually) when there's less road maintenance...

    The digital cable channels don't suffer from this at all, and I presume satellite radio doesn't either. FM stations vary quite a bit on this.

    Why do they do that, anyway? On the radio stations around here, the DJ will be introducing a song, talking about whatever, and the song will start while they're still talking. Just the instrumental part though. The DJ always finishes whatever he's saying just before the lyrics of the song actually start (I'm convinced they have some kind of countdown display that tells them exactly how many seconds are left before the lyrics of the song start). Are they just trying to be smooth, or do you think their license agreements for the songs actually requires them to talk over some portion of the song, to try and discourage exactly the kind of activity you described (i.e., taping the songs off the radio)?

    Like I said, it varies a lot with the station and program. I'm pretty sure in most cases the explanation is that the DJs are idiots that really like the sound of their own voice. ;-)

    Exactly. I'm mystified that NASA doesn't talk more about underground habitation. Hang a few plasma displays on the wall and you might just as well be in Hawaii (minus the 1/3 G gravity of course;). Regular centrifuge use may be necessary to prevent bone mass loss.

    The 300 MPH winds shouldn't be a very big deal though - the atmosphere is so thin you'd hardly feel anything.

    I am in hopes that we will send a private mission to mars and not have them return. It would be far more useful to send a small mission on a one way trip, with a supply ship once a year. They could build a small base, expand our knowledge of Mars a million fold over what simple remote vehicles do today, just due to the fact that they would need all sorts of cpu power there. In addition, they would be able to control system there quickly.

  16. Re:I'm confused on Improving The Java Core Library · · Score: 1
    Unfortunately I missed this topic when it originally came up, but this thread seemed a good place to throw in my (belated) two cents...

    When I read the linked page, I found more like a Java version of C++ -- it looks as though a lot of those libraries are there to overcome the very strengths/weaknesses (depending on your application) that most differentiate the two languages. If you want to use C++, why not just use C++?

    I don't see why you think JADE is a "Java version of C++". If you're referring to the .realtime library, it is mainly a factory implementation that recycles objects when "new" ones are needed rather than creating them from scratch. This is a good design pattern that also works well for C++ - heap allocation is also expensive (and non-deterministic) for C++. For Java, it brings the benefit of determinism, which is very nice. Java has many strengths over C++, but its one major weakness has been a lack of determinism. Long (or even noticeable) garbage collection pauses don't work well for realtime applications (like games for instance;). com.dautelle.jade.realtime addresses that issue.

    BTW, on the "make it a part of the core library" front, I don't really see the necessity. Putting it in Jakarta would be O.K., although it seems like something of a strange spot for the realtime part. At least the com.dautelle.* namespace gives the author some much-deserved credit! :-)

    This is a specious argument against the use of a national ID - as in "identification" - card. I wonder how B.F. feels about this quote being used when someone feels that their "personal liberty" is being threatened, in comparison to the liberty and freedom of the general population?

    Were B.F. to have an opinion at this point, I'm quite sure it would reflect the fact that "personal liberty" and "the liberty and freedom of the general population" are the same - you can't have one without the other.

    When this quote was penned, Franklin was reflecting on the actions of some colonists who were taking the side of the English in order to keep English soldiers from imprisoning other colonists... and possibly themselves. The English were an occupying force, and there were *NO* legal means which could be used to appeal their decisions. If they felt you were a threat, you were imprisoned without recourse.

    I suppose you mean like those arrested and held indefinitely without formal charges today in America? But I digress...

    The legal system in the US may move slowly, but it *does* move and it *does* work. Court decisions have said that the prisoners in Guantanamo are now required to have legal representation, and some may even be released. Abu Ghraib was being actively investigated *before* the media "caught on" and the case became "interesting" - look at the public record. And, the fact that we are having this discussion in an open forum without the fear that the "gummint" will arrest us, simply means that we are free to do so.

    Yes, it means that we are free to do so...today.

    However, any thinking person should see that our liberties are at risk, from many different directions. For instance, the right to peaceful assembly has been seriously undermined. Now, dissenters are allowed to assemble - in cages well away from public view. What a travesty - the DNC should be ashamed!

    If the ID card is solely used to *prove who you are*, then it follows that you are who you *claim* to be... and *probably not* someone who wishes to hurt, maim, or kill as many grandmothers, wives, or children as he/she can. The assumption is, of course, that we haven't naturalized or home-bred more Timothy McVeighs -- something no government can defend against without totally invasive security measures which would never pass Congress' muster.

    In other words, it's an ineffective measure which does very little besides erode our freedoms further.

    Reflect on the fact that most of the 9/11 terrorists would have had shiny, legitimate national ID cards...now what good would they do again? And at what cost, both in dollars and liberty?

    The problem with a national ID card isn't freedom, it's forgery: how do you prove that the ID card is not fake?

    That is another problem. You know, you're right - I think instead of national ID cards we should have bone-implanted RFID tags (as 161 Mexican officials have). Anything for safety, right?

    Let's get real. Those who wish us harm are not targeting the military. If they were, the 9/11 attacks would have been felt at military bases around the US and the rest of the world. These malcontents are targeting *us*.

    And, miraculously, we've managed to avoid any further attacks for nearly three years - without national ID cards. How is this possible?!?

    Meanwhile, ~150,000 of our fellow citizens (yes 50 times as many as died on 9/11) have died in traffic accidents. Let's keep our risks in perspective, eh?
