    Yes, although you don't have to be autistic to avoid contacting your mom by letter or phone...

    But here's a truly hot recipe for making your Mom (or whoever) a lot happier:

    1. Get your mom on-line.
    2. Teach your mom how to send you email.
    3. Reply to her email using the same compulsive zeal that makes you a Usenet Wraith or "Karma +30" Slashdot poster.

  2. Re:Not the first study on Scientists map schematic of brain's fibers · · Score: 1
    I must point out that this is not the first work showing brain connectivity. In fact, people have been doing this for a decade with MRI, and before that with more invasive means. For example, Douek et al. (Journal of Computer Assisted Tomography, 16(6),923-929:1991) colour mapped myelin fiber orientation in the brain using diffusion weighted MRI.

    Well, people in the field know that there has been lots of work going on in this topic (computing the diffusion tensor). It is, after all, a fairly obvious thing to do. What seems to be novel to me about this is that they used the DT to trace out some very long fiber pathways, and they did it with just a wimpy 1.5T Siemens Vision scanner. And the big surprise to me was that the WashU folks beat the MGH group (among others) into print on this topic.

    Coupling this information with functional information (regional metabolic activity in the brain also measurable with MRI or PET or SPECT) can provide valuable insight into brain function and dysfunction.

    As Barak Pearlmutter mentioned earlier in this thread, this information is an even better fit for techniques that provide much better temporal resolution than fMRI, PET, or SPECT; he mentioned MEG (magnetoencephalogram, although EEG-based methods can also contribute, and I can't help mentioning the amazing new "shoot lasers through the skull and get optical imaging data" technique known as EROS, currently being developed at the University of Missouri and elsewhere.

    This modality - MRI - gives excellent spatial resolution. Unfortunately, it is not so good with temporal information, which can be at best on the order of a second, which is much slower than the brain processes information.

    Hi, Barak. Being basically a cognitive electrophysiologist, I, of course, have to agree with this, but I do want to point out that the Raichle paper is phenomenally important in that this is the beginning of doing real dynamic processing studies.

    The logic for how to use this data is straight-forward enough; you mention MEG, but another technique that should work really well with this the event-related optical signal (EROS) which was pioneered by Dr. Gabriele Gratton at the University of Missouri, and now spreading rapidly elsewhere.

    Our code base, both for signal processing and for visualization, is all developed on Debian GNU/Linux machines (both i386 and Alpha) and will all to be released under the GLP. It is also all being ported to SGIs and to large Linux clusters.

    That's great! I think you should issue that as a challenge to many other labs out there.

    If you're interested in figuring out how the brain works and want to get a PhD or MS in CS at a really funky department while hacking Linux and playing with gonzo brain imaging data, don't be shy - get in touch.

    What he said, except ours is a Psychology department (so the department is psycho rather than funky).

    All kidding aside, the geek masses yearning to go to grad school despite the difficulties of being a grad student would be well-advised to take a look at the advances being made in human brain imaging and cognitive neuroscience when mapping out their careers.

  6. Re:in answer to the original questions... on Ask Slashdot: Comparing the GUIs · · Score: 1

    Now here's a good news/bad news situation. I already used my five moderator points today on another thread, which meant that I couldn't moderate up any of the JWZ posts on this topic. On the other hand, that means I can add my own amplifications on the topic of how much X sucks.

    Another sucky thing about X is...is...

    Oh, what's the point. I've been an X user for almost fifteen years now. And I'm one of the lucky ones: I've never had to program for it. Fifteen freaking years and I have finally almost got a desktop I actually like. And that's only because the GTk+ people did an end-run around X and I've got a desktop machine that would stomp any supercomputer from the 1985-ish era of the X design. So I have to say that X is quite lovely if you have the luxury of running it on hardware 32,000 times more powerful than it was designed for.

    But then Zawinski writes:

    But none of that matters. Why? Because it doesn't matter how much X sucks, because X is entrenched. It works badly, but it works well enough. It is the de-facto sub-standard. It cannot be replaced, or even fixed, without rewriting every single graphical application you have ever seen, and that's just not practical.

    I feel your pain, but I'm not sure even I am as darkly pessimistic as this. I guess the claim is that replacing X would be too much work, but I think we have plenty of evidence that there are people out there for whom time and duplicated effort have very little meaning. As I write this, there are hundreds of programmers slaving away at the Wine Project in order that we might one day be able to run Microsoft Word in bug-for-bug compatibility mode. Zawinski has already pointed out the amount of wheel-spinning that has gone into the eleventy-seven different toolkits that you can run under X. Emacs now can have a built-in web browser (disclaimer: yes, I sometimes use it) and I personally know the guy who wrote its spreadsheet mode.

    No, I think there's enough random energy around to write a completely new GUI for Unix and hack/slay/port all of the most useful applications to it. There are already two or three groups of people who are working on the next X itself.

    I'm not sure all of this is the wisest use of one's time, of course, but there you go. Worse may usually be be better, but this cuts both ways. I remember when Linux was still in the .95 days and there was a serious question about how long Linux thing could go on before the *BSD people saved us all. It didn't happen that way for a variety of reasons, and *BSD was a far more likely candidate for world dominance in 1991 than X is in 1999.

    I'm not sure I understand the fetish for ultra high resolution myself. But I can give a really good reason for maximizing browser windows. Some of us use features of current window managers under X that allow us to have a desktop 3 (or 4) screens wide and 3 screens tall, and we can flip back and forth between them without ever taking our hands off the keyboard. In that kind of a system, there's no particular reason why you can't have three maximized browser windows available at once. I know I do.

  11. The problem with operator overloading on Java for EGCS · · Score: 1
    I agree overloaded operators are easier to use, and it makes Java very verobose (as well as increasing the inelegant distinction between objects and primtive types).

    Indeed. Every sentient being reading this should immediately snarf the paper written by Guy Steele for OOPSLA '98 entitled Growing a Language which makes this point so forcefully you will be dazzled.

    The best place to find this on the net is apparently hanging off the web page of the soon-to-be-slashdotted Phil Wadler; download the postscript version this instant.

    The problem with operator overloading is that in long peices of code, it makes it hard to work out what is really going on - you cannot tell whether a + b is just an integer addition or some function call, and then you do not know whether it has the properties you would expect of +.

    This is a bit of a red herring. Overloaded methods are at least as open to abuse (e.g., some clown could always define a "print" method that reads files instead...). What they don't do is invite the same expectations. But I think Java has a way out of this: you could have classes implement a standard interface that includes the operators you want to use in your class.

    I've always found Java ironic that way; they come up with a truly cool idea like interfaces, then still use inheritance all over the place just to be OO, I suppose.

  12. okay, but... on The Myth of QWERTY · · Score: 2
    So, how does this article explain that the people who win the speed-typing contests are always Dvorak typists?

    Okay. If this were true, how would it be relevant? Meanwhile, if you take a look at the URL posted on this thread from the U. of T. Dallas researchers, you would find that this isn't (or, at least wasn't) true. Good typists who had a vested interest in typing really fast are the people who win (and have won) speed-typing contests. These days, there really aren't very many typing contests, and I would suspect that the only people with a huge interest in entering or winning them are people who sell either "improved" keyboards or "improved" training programs.

    Additionally, the article doesn't say anything about RSI/carpal tunnel -- 'the black lung of hackers' (thanks N. Stephenson for that wonderful imagery!). I was under the impression that Dvorak reduced the damage due to this ailment.

    Typing-related injuries are definitely a real problem. But, I just checked the recent psychological and medical literature (Psychlit and Medline) for any references to studies that claimed RSIs could be reduced by keyboard layout. I found nothing, although it could be hiding under a different set of keywords than I used.

    This is not to say that current keyboards are perfect; Donald Norman, in particular, has noted that one could potentially improve on the typing speed of either QWERTY or Dvorak with other designs. It is also true that until very recently, nobody even thought much about designing keyboards or keyboard layouts to minimize the effect of carpal-tunnel-like injuries. But I would have to be very skeptical about anybody's untested claim that their favorite keyboard reduces typing injuries.

    I'll make a wild guess that you're getting burned by some historical confusion concerning Tcl/Tk interfaces used by Perl.

    Officially, the vice president can preside over the Senate. Once in a blue moon he or she can break ties in the Senate. The vice president is usually allowed to attend cabinet meetings.

    If the president resigns or dies or becomes incompetent according to some set of criteria, the vice-president can become the president. Officially, the whole job is basically attending meetings, breaking tie votes in the senate, twiddling your thumbs, and waiting for people to die.

    Unofficially, the vice president also gets to attend state funerals for people who weren't quite important enough for the president to bother to show up. That's more waiting for people to die.

    Then after four or eight years of thumb-twiddling, the vice president gets to run for president. By definition, running for president involves saying idiotic and contradictory things to all kinds of people. And also smiling a lot.

    Put it this way: if Al Gore had actually said "Well, the internet is just one of those things that exploded on the scene and surprised the heck out of all of us, even though I always kind of thought it had some potential," he would have been honest...and just as boring as ever.
