Sure, DARPA has future warfare in mind. But so many technologies developed for military use end up in the private sector anyhow.
Autonomous vehicles would be very useful for the private sector as well as for the military. In fact there already exists agricultural vehicles that are able to drive themselves. These don't have obstacle avoidance, but merely follow GPS coordinates. They do travel relatively fast (~ 20 mph) and can steer the vehicle more accurately than a human operator could.
Make a robot that will successfully find a parking spot at the mall!
That would be a practical appliation. You'ld just drive up and let yourself off at the mall entrance and let the car worry about finding a parking spot while you're shopping. Push a button on the fob and the car drives itself back up to the entrance and picks you up.
I've thought about how using stereo from motion would work as well. I think that in order for this to work one would need to have a fairly stable mount for the camera. Then you'ld probably want to have some accelerometers in order to help in correlating the frames of successive images. I figure that for the grand challenge you'ld probably need 5 or 6 cameras (fairly low resolution 640x480) with various focal length lenses, short for looking near the vehicle, long for imaging a small region well ahead of the vehicle. For some of the cameras you'ld need to be able to point them with in a limited range. (Specifically those with the longer focal length lenses). Three wider angle length cameras would be fixed mounted -one straight ahead, one looking to left ahead, one to right and ahead. These would be mainly used for vehicle orientation and preliminary path planning. One of the cameras would have long lens and be looking ahead in the planned path of the vehicle for obstacles. One ould be looking medium range ahead in the planned path obstacles. You would need some fairly good processing power for image processing behind each of the cameras. And you'ld need a master computer to coordintate everything.
I may have to look into seeing how to process camcorder images on my computer, Hmm.
Do I think someone can win the Grand Challenge next year? Maybe one of the top three teams this year could. For those teams it may only be a matter of fixing a half dozen deficiencies. After all they did manage to go 7 miles. I'm optomistic that it will be done.
I'm wondering just how little (much) radiant heat it would take to kill most life. Another post mentioned that breathing hot air tends to scald the lungs and lead to death. Someone more familiar with medicine or firefighting than myself would probably have a good idea of the lowest air temperatures at which this might occur. I'm thinking that air temperatures as low as 150-180 degrees or so, for several minutes may have been enough to kill most land animals, if not protected in some way.
If that were the case then it may be that the heat would not have been enough to kill off all the plants. I could understand how animals in water or having refuge undergound would readily survive this situation. That still doesn't explain how birds (or their dionsaur ancestors) would have survived.
I think you hit the nail on the head. It promoted a social bond. Individuals within these social bonds were more likely to successfully produce offspring.
Aren't you supposed to cook them 1/2 hour per pound?
(How much did some of those large dinos weigh anyhow?)
Wilma and Betty would have spent a long time preparing this meal.
The grandparent said it was 60% of the present size at the time of pangaea, which was a great deal earlier than 65 Million years ago. Even so, I would take that theory with a big grain of salt. There would have had to have been too many asteroid impacts during that time for much life to have existed
I think the idea is that extending the language would be more or less akin to using templates or wizards. You wouldn't actually be telling the compiler how to produce object code, but you would be telling the compiler that when it sees your new keyword it's supposed to look for certain patterns, then 'generate' some additional source code.
Think of it as a way of defining a 'wizard', or of doing something that you might do with a template.
What benefits does XML have over EDI when transmitting business data? I know of none. The only reason this substitution is happening is that XML happens to be the big buzzword among PHB's.
For something - retriveing stock qootes over the internet, I certainly can see its use. But when you're talking about company A's computer talking to company B's computer, maybe EDI is a better way to go, especially if company A or company B is still using dial-up lines (there are a lot of small companies out therer), considering the verbosity of XML and the efficiency of EDI.
I'm more specifically referring to a debugger which will, when stepping through the code, be able to display and debug modules written in several different languages.
I know this is possible with HDLs. I know of an environment that can debug a model consisting of modules written in VHDL, Verilog HDL and (a version of ) C.
As you say, linking an executable from modules of more than one language is old news.
> that next-generation programming systems will combine compilers"... but "should combine...
Does there not already exist development systems that can handle code written in multiple languages? (e.g. some of the modules being written in C++, others in Pascal or whatever)
Certainly not the XML part (too verbose). Parts will be true. Extensible compilers - yes. Moving away from 8-bit ascii source files - yes. Extensible debuggers- yes.
I've gotta wonder, however, if this won't effectively mean that differnt organizations use different variations of the same language, which may be confusing for a developer switching jobs.
If your talking about the Van's Hardware review, please find a fair review not done by an AMD fanboy.

Yes it was the Van's Hardware review. I didn't get the impreesion that the reviewer was an 'AMD fanboy' since one of the Intel processors was also mentioned as a good choice. Just the same, I'll keep my eyes opened for other reviews of the effeceon processor.

Does that mean we can expect their next lawsuit to be filed against Rand McNally?
I always thought of it as that fudge factor they put on the financial statements to make the assets and liabilities balance out.
I'ld be willing to bet that for OEM's, the cost of a moderate speed sempron processor would be below $40US, maybe even below $35.
Yes, Moron.

Gee, that's not what I've ever read. What is your source for these statements?

Sounds tasty. A feast for the entire village.

Wait till C++ and Jave are finished? They aren't finished with FORTRAN yet.
What!

There's also a PHB interface to SOAP, called a soap dispenser.
