The MIR software is more a continuation of the model-based diagnosis work that came out of Xerox PARC and other places in the past decade.
Model-based diagnosis uses Bayes' rule as do Bayes' nets, but it is specialized to the problem of diagnosis, and now recovery/reconfiguration. This specialization allows very fast inference on this restricted class of problem. There are some systems that do diagnosis strictly with Bayes' nets as well, but MIR uses additional techniques such as conflict directed search from the model-based diagnosis world.
The MIR system on DS1 was provided by an inference engine called "Livingstone", after the doctor and explorer, which was written at NASA Ames. You can grab papers and other info at NASA Model-based Autonomy Home Page.
NS 4.0+ and IE 4.0+ come really close to supporting navagation completely via keyboard, if not completely. Also, i think some of theese browsers should offer customizeable keybindings. Then someone could set their own set of keys do things like bring you back x number of pages, add the current page to a specific folder in your favorites, or run a macro.
David Futrelle lost me the moment he wrote, "Britney Spears has nothing to worry about." Not only is he assuming that popularity equals quality, but he thinks that MP3.com is supposed to operate like a traditional record label and produce exactly the same sort of music. This is so misguided as to be laughable.
MP3.com is GeoCities for Musicians. When GeoCities started, they had this crazy idea that they could give one megabyte of web space to anyone who wanted it. Most people laughed at them and said they could never pull it off. They eventually grew into something that Yahoo thought was worth...
MP3.com is the same way. Some GeoCities pages are great, and some stink. The same goes for bands at MP3.com. Just because Big Poo Generator sucks -- and let's not lie, they suck -- doesn't mean they're indicative of every band at the site. Would Futrelle judge all of GeoCities by one guy's tribute to his dead goldfish?
This isn't even delving into the musical fallacy of comparing Big Poo Generator with anything that gets regular airplay on eMpTyV or "hit radio." You might as well compare Miles Davis and Weird Al. Let's talk about Red Delicious, Ron Sunshine, Bio Ritmo, Electrostatic, Jen Cass, Lotusland, Alien Fashion Show, Blue by Nature, Li'l Ronnie & the Grand Dukes -- quality acts making quality music that the industry can't be bothered to promote. Artists of this caliber can now go out and get heard on a planetary scale. I wouldn't have heard of these people if not for MP3.com.
That's why MP3.com is important -- it gives a voice to the unsigned, whether they want to get signed or not. I'd venture to say a good chunk of those 11,000 artists are just hobbyists who don't really care about fame and fortune, just like a lot of those people making web sites on GeoCities aren't looking to get rich from their sites. Comparing MP3.com to the music industry as we know it is foolish, because MP3.com is NOT the music industry as we know it. It's a completely different (if not particularly original) paradigm that exists outside the music industry box, and it should be judged as such.
And it definitely shouldn't be judged on the merits of one horrid band with a song somewhere in the middle of the Alternative Top 40 -- not when Red Delicious has 3 songs in the Alternative Top 3, anyway.

Some comments on Remote Agent from R.A. Team

Hello.
Remote Agent is able to reason very effectively within a domain that has been described to it. Through this reasoning process (or actually processes) it's able to come up with solutions that the developers did not explicitly encode and respond to situations they did not envision.
One may call that AI or not.
RA does not contain program code to handle every contingency that could have occured. We could have written a program that covered just the contingencies we knew we were going to inject during the flight test, but the full model of Deep Space 1 that Remote Agent has used during demonstrations on the ground has something like 2^80 states.
Remote Agent has declarative models of the spacecraft's hardware, resources (such as electrical power) and so on, and uses a set of reasoning algorithms to continually find the actions which push the spacecraft towards its goal, even in the face of failures or unexpected outcomes. The reasoning part of Remote Agent is reusable from mission to mission, while the model of the spacecraft or what have you is developed from reusable parts each time.
There is an analogy with computer graphics: your rendering engine does not contain explicit instructions on how to draw a velociraptor, a space craft, etc. It has a set of general algorithms (ray tracing, texture mapping, etc) which can be applied to models which describe a world.
Similarly, Remote Agent has some general algorithms (planning, diagnosis, recovery, plan running, etc) which can be applied to different descriptions of spacecraft, life support systems, etc.
Some other random comments:
Since this was just an experiment, the failures we injected were carefully chosen so that the recovery RA would recommend had as little risk and impact on the spacecraft as possible.
Therefore the recoveries are fairly trivial, such as switching control modes in the attitude control system. In simulation, where there is no spacecraft at risk, RA has taken on much more critical situations such as engine failure during the Cassini orbital insertion.
I view personally view this experiment as the "thin end of the wedge" for AI, or automated reasoning if that's a less controversial term, in space.
RA has done a simple demo in space, more complex scenarios on the ground, and now is being evaluated by a number of NASA centers for future missions. At the same time, a great many people are working on systems which improve upon RA's capabilities.
Another post suggests that it takes an hour for Remote Agent to determine that it can switch thrusters after a failure.
On an Ultrasparc or my Linux laptop this takes well under a second. On the rad-hard (read slow) spacecraft processor I believe it takes on the order of a minute do to the actual diagnosis and make the recovery recommendation.
Unfortunately, there is legislation that states that if you have a local channel, you cannot purchase rights to watch the 'networks' on a Dish - the local channels have preference.
So basically, if an antenna works, get a GOOD antenna. I believe you can hook both that and the dish up to the reciever by the TV
I don't know how much you all know about dual Celery systems, but bxboards.com gives some really interesting info on it. Of course, I would suggest as they do "don't try this at home kids." For those weaker of heart. ComputerNerd is offering dual Celeron systems that are 'supposed' to be overclocked.
I think it is kind of tall, I mean it does have to fit 2 370 side by side, right?
Hey, ive had a DSS dish since before it was cool. You can now get em for practically nothing if not completely free. We paid like 499 for ours, and last time I saw they're giving em away if you subscribe to just the standard DirecTV package... Easy to use, easy to install, cheap (monthly fees are low even if u rent movies), and you can get good ppv on there....
And I have no problem running Javascript from a promonent site like Forbes. They have a vested interest in not putting anything squirrly up on their site.
Well, they did put squirrly code on their site. My screen got filled with javascript errors, and the java applet never ran. I'm using Netscape 3.04 and Linux.
Actually they don't own the formula, it's just a mixture of different stuff and mixtures can't be patented. That's why companies hold their recipes so secret. The only restriction that would apply is trademark law. You could copy Hershey Bars all day long, as long as you didn't call ita Hershey Bar

I disagree whole heartedly! I both think and feel that sending Man into Space is paramount; I mean think about it this way Earth is the only stomping ground of our civilization, if Earth goes we go. Therefore, the more that we push sending Man into Space and more directly seeding Mankind on the Moon, and planets like Mars ensures that should something happen to one locale in Space then at least something of Mankind would survive. The problem today is that the "leaders" in governmentally pushed space exploration (the USA) cannot get its populace behind spending more money on manned or any other type of Space exploration. Think about it, how long did it take to get the Space station in place, and we continue to sit on our "asses" looking at the moon, Mars and the asteroid belt, dreaming about them and doing nothing to bring them to reality (don't get me wrong there are some porojects whish are aimed at this but they are few and far between). If you want to talk about economics well, my guess is that there are plenty of precious resources within the asteroids which are waiting to be mined even as we jabber about the econonic feasibility of Space ventures (be it govermentally or privately funded). To get back to my major point a whole lot of us need to awaken to the fact that if there is a push in the direction of Space it will sprout new industries to support itself thereby rendering the enconomic issue a moot point. And as a side benefit of making local Space no longer a frontier we spread the seeds of Mankind onto multiple types os soil where it can both grow and wither, but we get out there.
in that case you are arguing for the stealing of food from the local store, medicines from the drugstore (or hospital) and maybe even bypassing the electric meter so that you can have heat without paying!! Where would it end if everyone took that attitude? Gun law, the one with the biggest gun survives. "Dont steal" was a rule given to us about 4000 years ago, and we still argue about keeping it? We seem to be no more civilised than they were then.
In the June 1999 issue of Linux Journal they had an article(page 82) about the Totalisator Administration Board(TAB) of Queensland using Linux for their betting booths. Now wouldn't censorship put all of these guys and gals' hard work to nothing? I'm sure the representitaves in Austrailia like to indulge in a little betting after the daily round of votes...but I could be wrong.
