  1. Re:Amazon DOES NOT SELL USED BOOKS !!!! on Authors Guild To Members: De-link Amazon.com · · Score: 1

    I was under the impression that you were suggesting that Amazon being a only a broker in this situation completely puts them in the clear as far as the authors' complaints.

    You got modded up! No fair. I'll have to think harder next time.

  2. Re:Hey, remember SMTP? on Programming Jabber · · Score: 1

    It seems to me that the essence of these IM applications is that they help people find other their friend's IPs when they change, either by logging on/off ala the modem era or changing computers. This problem has definatly already been solved.

  3. Re:Uh... Police State? on Simulating Societies · · Score: 1

    You missed the point altogether. Simulations like this show that there is nothing you can do to engineer the outcome you want. The emergence of the new equilibrium happens wheither you like it or not. If you were add a police state to this simulation you would have two choices.

    First, you could make the police agents prefectly incorruptable. This actually may work in making the system honest quicker but would not reflect real life because there is no such thing as an incorruptable real life human being.

    Second, you can make the police agents corruptable just like the bureaucrats and the citizens. In this case you are going to find yourself right back where you started when there were no police at all. The dynamics may be a bit different. There may be cycles or something of that nature but the outcome will likely not change.

    So the simulation actually advocates nothing in real life except just waiting and seeing what happens under the rules or our reality...certainly not a police state.

    That is like saying that Nike doesn't sell shoes made in sweatshops. Nike tries to distance itself from it manufacturing by doing the work through contractors.

    Just because Amazon acts as a broker doesn't mean it's not part of the sale. On the other hand I side with Amazon on this one. The Authors are whiners and if the whine about this they need to whine about all second-hand book stores.

    So what is my point? Don't go spreading the idea that brokers are not responsible for what they are brokering even if it is not such a big deal in this case.

  5. Retinal Scanning Displays on Monitors for People with Poor Eyesight? · · Score: 1

    There is some preliminary documentation showing that Retina Scanning Displays are a better display for those with low vision. This is currently being investigated by the Low-Vision group at the Human Interface Technology Lab at the University of Washington. Retinal displays are currently commercially available from from a company called Microvision. I'm not familiar with your condition but I can ask around to see if any of our test subjects had it.

  6. Make them write an interpretor on Ask Kent M. Pitman About Lisp, Scheme And More · · Score: 1

    My program at the University of Washington is very much against the "get them ready for industry attitude" which some of the students don't like. We learn Scheme in a class called "survey of programming languages" as the first of a series of four languages meant to touch on the difference between functional, pure functional, procedural and object oriented code. Early in the course we write programs for Scheme in Guile. The final project is write an interpretor of Scheme in Java.

    I think this is the best way to sell Scheme. Once students see how easy it is to write an interpretor for it they get all kinds of great ideas of how to integrate it into other applications.

  7. University of Washington making the switch on Java as a CS Introductory Language? · · Score: 1
    This has been a huge debate in the CS&E department at the University of Washington. Our two introductory to programming courses are known to be one of the best around. They've been taught in C/C++ for years but starting this fall they will be taugh in Java.

    The move to Java is not, however, motivated by the fact that it may or may not be more valuable on the market. Those who enter the major currently have to learn Java anyway in our programming languages class. Our department is really into teaching the concepts of computer science and not the particular applications. It has been decided that Java a better language for teaching those concepts, without the pain and suffering associated with dynamic memory allocation, dangling pointers, useless error messages, etc.

    There is a good paper by Ben Dugan, who argued strongly for the switch to Java today and against our switch from Ada to C/C++ 7 years ago.

  12. --Someone who actually knows about this stuff!!! on Retinal Scanning Displays · · Score: 4

    I never realized how annoying /. is . I'm the only poster here who knows about this stuff and I'm way at the bottom...

    I work on that exact thing at the Human Interface Technology Lab at the University of Washington. Right now I'm doing some work to identify doorways and staircases for the purpose of superimposing over the users sight. The VRD is great for this because it does not block normal sight Also, since the light enters the eye over a small portion of the lens, people with lens damage and such can still view the image.

    I've seen some earlier posts that suggest than the VRD is/will be way to expencive. Let me tell you that it is not. The complexity of the device is much lower than a CRT or LCD screen. It takes us about two days and $15 dollars worth of readily available parts to construct one by hand. (Minus the computer to drive it of course.) I suspect a good and near invisible VRD will be available in 4 years for less than $100.

    As far as the shooting lasers in to peoples eyes, it is not as bad as you think. People commonly associate lasers with high power. Our lasers can't cast a visible spot on a white piece of paper.Getting human subject approval is not picnic though :-).

  14. No difference on Computer Science vs. Computer Engineering? · · Score: 1

    In my program (University of Washington) the only difference in requirements is that CE students have to take chemistry and CS students have to take Foriegn Language. CE students have to take all the hardware courses while CS can take them but only as electives. Our advisors have told us that career-wise there is no difference in what jobs out graduates get. I hate chem so I'm CS.

  15. Explanation of Our Program on Univ. of Washington Announces First Nanotech Ph.D. · · Score: 1

    I've read a few comments saying that it is too early to have a nanotech degree. Last week I was at another function of the College of Engineering here at the University of Washington. The Dean gave a brief explanation of why we are the first University to have such a degree. Over that last couple of years the College of Engineering has had a lot of older profs retire. The University has been been very aggressive in replacing those old professors with the best and brightest. Many of those new faculty decided to come because of our superior facilities in Microfabrication (right next to my lab) and Photonics. As a result we have a faculty whose main interests lies in micro- and nano- sized machines.

  16. CS department at UW really cool about that stuff on Coding Classes & Required Development Environments? · · Score: 1

    My department at the University of Washington is really cool about letting you develop however you want. It's mostly rooted in the fact that the TA staff is a bunch of OS snobs and refuses to correct platfrom dependant work.

  17. Resort to threats and namecalling on Sony VP On Stopping Napster · · Score: 1

    The most laughable thing about Heckler's threats is that he actually thinks he has the ability to shut it down by technical means. Empty threats and going-for-the-moral-highground rhetoric is really starting to get old. Before their message kinda made sense to the point that you could listen to what the industry had to say but remarks like this are evidence that they are starting to crack. The CD industry is doomed. They know it. They know they can do nothing about it. The first company to admit defeat, be a good loser and COOPERATE (this is getting old too I admit) with their customers is going to reap the benefits. This is encourageing.

  18. CHI research at my lab on GUI Research - Is it Still Being Done? · · Score: 2

    I am a student at the University of Washington which is home to the Human Interface Technology Lab. Some of my colleages are doing some interesting new work. Gesture recognition is one thing we are working on. We have one application of gesture recognition that does finger tracking near a screen. We have a display of that that will be at SIGGRAPH 2000. PUI or perception user interface is not being done here but I am aware of it. That is where movement of the eye is interpreted as input. Augmented or Mixed reality is something new and interesting that brings the computing environment out into the real world. We are doing some really cool work there.
