Attending one of the Universities connected and researching the Interent 2, I can safely say I have heard a lot about it. Achieving the kinds of bandwith and latency required for such things as remote surgery is exactly the goals of the researchers putting their time into this project.
Not only that, but there are other opportunities in "remote" surgery that this technology opens up. What if the specialist could see the surgery and communicate to a general surgeon on the patient's end. If the general surgeon used this haptic scalpel, it could not only enable him to better work in areas of the body he is not as familiar with, but the remote specialist would also recieve a lot more data to diagnose the problem and give the general surgeon instructions. If there are bumps on a heart that the general surgeon doesn't know should or should not be there, a haptic sensor connected to a 3D input device could allow the general surgeon to produce an image map showing the bumps, and the remote specialist could get a 3D image or even better, which could be fed back into another haptic device, allowing the specialist to feel the heart without even putting his hands in the patient's chest.
I swear this came up already in the discussions about SIGGRAPH 2001. The Researchers who came up with this were showing it off. In response to the earlyy post about electrical currents and such, it doesn't have to be an electrical current feedback, it can use any kind of feedback, optical, density, etc. Basically what this device does is it senses the boundary line between two different substances (i.e. water and oil, white of an egg and its yolk...) and gives them a very strong tactile feedback to keep them from pushing through - however one can override the device and still push through.
I got to try it at SIGGRAPH. As an example they had a small clear tank filled with water and something heavier beneath (dunno what it was...obviously nontoxic though). They handed you a pen to stick into the mixture and try as you like there was no way you could determine where one liquid stopped and the next began simply by touch (the liquids were different colors). Next they let you try with the haptic device. A clear plastic or glass wand the same size as the pen which was connected to a robotic arm. Every time the wand touched the surface of the lower liquid, the robotic arm would kick in and keep you from penetrating it with a fairly strong force that would take some serious concious effort to overcome. Basically the device let you literally feel the line of difference between the liquids, which you would otherwise never be able to dectect by touch. In fact, just to prove how well it worked, they would from time to time bump or stir the tank so that there would be visible ripples in the intersection of the two liquids. The haptic device still worked great at letting you feel the bumps and valleys created. The video/slideshow on the wall behind the display showed the hard boiled egg example among other things. The person wielding the scalpel was able in a single quick cut (less than 20 seconds) cut the white off the yolk without cutting the yolk at all. This could allow doctors to cut through a layer of skin or tissue without cutting what was underneath. It doesn't have to be recalibrated for each and every set of materials used, just the one that it is pentrating. It detects differences in properties (such as conductivity) and won't let you penetrate anything but what you set it to allow you to pentrate.
The question isn't a matter of protocols, its a matter of the content delivered. If client apps are recieving content as part of a proprietary system, then replacing the server often means replacing the client apps as well - or else converting the server app. For instance, if a company moves off a UNIX mail server to a MSExchange server because of the enhanced workgroup scheduling features it provides...then all the client machines will need to start running Outlook....and my example of stock trading systems is a little more insular and has less options available than mail systems. Its more like switching from an Oracle database (and clients) to Filemaker or Access.
If they move their servers from *NIX to Win2k, it is a gaurantee that for as long as they have those servers, they will be running a Windows desktop environment rather than a customized LINUX desktop. Remember that in the 1980's the stock brokers were all using customized, proprietary terminal systems for trading and watching the market. A lot of those companies are still using (albeit heavily modified to meet today's standards) platforms based on those terminals. If the major traders like Ameritrade (as mentioned in the memo) start moving their servers to Windows, it provides an example to the others at which point you can say goodbye to all those proprietary terminal systems/services which would have been a perfect market for LINUX. After all, one of the main points of the memo was to get Microsoft's size 22.5 (US) foot in the door. Once one app/service gets its foot in the door, the rest will soon follow.
Because there is no server version of WinXP (yet)....the memo was focused on server OS sales....which will of course in turn determine the client OS used.....
As an architecture student who is also a geek - I'm curious as to how you made the transition to the technology sector. What prompted you to make the change and how did you do it? Was there anyone instrumental in providing you an opportunity? Do you still try to make a connection back to your architecture roots?
I was at SIGGRAPH, they are using a 34" (widescreen proportions) plasma (HDTV?) display, with absolutely no visible pixelation.
As for the speed difference, remember that the SGI cluster square used was handleing composite rendering, and as such the various "layers" (specular, shading, etc...) can easily be split up to significantly increase the speed. The NVidia solution doesn't break it up the same way, and simplifies a lot of it (the hair for instance!)
Lighting and radiosity is significantly downgraded from the original, and her hair is definately not to the same level as in the movie, and the bumpmapped cloth textures seem much more pronounced....but....this is far beyond any display of on the fly 3D rendering compared to final movie-quality product.
.....that there is 6 times as many posts here on/. than on the original Newsforge article.....
Does that mean/. is running the 1.4Ghz and Newsforge the 1.33?
Can we say 3dFX?? How long was the Voodoo series considered the "premimium gaming card" simply because most games had a couple of cheesy little effects (which were normally 2D) designed for the 3dFX engine? And you think that kind of practice will change? Of course not.
this "zero force" stuff was done in microwaves in the '80s using the whole electrical grounding through your fingers scheme....people hated it, they couldn't tell if they had pressed the button or not....it wasn't very long before the "fad" had worn off and microwaves had a slight force response to the buttons.....
there must be some type of tactile response, it could be very, very, slight, but its a matter of comfort in the human interface
Honda's low emissions sedan (I dont know the model) already has an emissions level lower than the air pollution on a typical Los Angeles freeway.....the air coming out the tailpipe is cleaner than the air going into the intake. Its already a "negative" emissions vehicle!
Remeber, GM invested heavily in electric cars and when they introduced the EV1 (codenamed "impact") in '98 they were the only auto manufacturer that was making a serious attempt at an electric car in the US. In fact, they were the only company that was prepared to meet the California law that stated that 10% of all cars sold in California must be emission free by the year 2000. No other manufacturer was able to put out a car in time and so they lobbied for an extension untill 2004 (when it will happen again, I guarantee it). So what if GM is researching fuel cells....they may even put a model into production.....but unfortuneately because people are too lax with the restrictions they set upon themselves, a fuel-cell car will go the same route as the EV1.
I've just finished wiring every room in a 106 year old victorian house with RJ45.
If you aren't going to use conduit for all your pretty wiring....you must use plenum rated wiring. This stuff prevents fires caused by shorts or whatever from traveling through the floorboards, walls, or cielings because of wires burning. Downside is that its quite a bit more expensive than the regular stuff (for RJ45 its often 4.5 times the cost). Although conduit might cost a little more right now than the plenum rated stuff, one of the benefits is that you can replace the wiring or add new wiring along the same path relitively easily. And the fire inspecter wont make you do it over again. Put in the biggest conduit that you can without violating the structural integrety!
Here's a good page for starting on that "total solution" misterhouse.net
Its a PERL based program that has built in support for lots of different smart housing toys, including X-10 stuff.....it also has links to all the stuff it supports.....check it out! it may be just what you are looking for
They're just trying to move their service to be more like AOL's successfull model by trapping the users into content they want to deliver....this is just the first step
The basic Bose home theater cube system comes with 10 cubes and an impressive horn subwoofer....has absolutely EXCELLENT sound quality, and its volume output will really surprise you. They are quite inconspicuous and very easy to mount. The only downside is that they must be used with a Bose amplifier.....of course, thats built into the subwoofer. Oh - and this 10 cube/subwoofer/tuner& costs approximately $1300 (US) - within your budget - and still leaves 200 for the tuner of your choice (i recommend the Bose one of course). If there is a Bose store anywhere near you (I know a couple in the Southern California area) DEFFINATELY stop by and take a look.....when you're making a $1500 investment its wise to shop arround a little and experience the products for yourself.

USC (Southern California) - one of the first 3 universities to be threatened by the Metallica lawsuit - even allows a certain restricted use of Napster on certain machines. When they originally decided to ban Napster the legal department stepped up and said NO! - But not for matters of "Student Online Freedom" - If the University bans Napster, it opens the door to lawsuits from students, faculty, third parties etc. who are pissed off that the university isn't banning another site as being offensive, or bigotted, or whatever. Personal freedom is not the reason, protection from frivolous lawsuits is.

I just purchased a IIIxe which I believe to be one of the faulty ones. Less than a week after purchasing it went into a crash/reset cycle that didn't seem to be prompted by anything. Luckily I had just backed up my data so I wasn't screwed when the Palm dropped everything. Luckily when I bought it (directly off the crate) at CompUSA - I opted for the $20 1 year warranty where they would replace it for free if **anything** happened. Needless to say - I will be walking into CompUSA today to get a replacement.
