First off, most stationary links are shielded. Not only to minimize interference but also to make sure that you don't waste output energy.
Second, most links are placed on the roof. Most people wanting to take a phone call do so inside the hopital, close to machines which can be affected by it.
And when it comes to hospitals I'd rather you don't take any chances as far as interference is concerned.
I've been subjected to a similar thing in a course on "Applied Atrificial Intelligence". We did an AI for checkers though, and it was not an introductory course. (It required at least one course in Algorithms and most had at least 3 years of experience of coding.)
I guess courses like that are good at times. (I know I've had my share of "killer assignments/labs".) As a lecturer you need to have a good knowledge about how much work your students have in other courses at the same time. There's nothing worse than having multiple assignments like these due in one week.

Hey, I was planning on trying something like this for a summer project. I haven't gotten around to it yet though.
Do you have your code still lying around somewhere or anything like that?
I really didn't enjoy Candide as much as I thought I would. From a literary standpoint it's a rather bad book IMHO. (Yes I know it's a philosophical rebuttal and not/only/ a book.) It's short though so you can read it quickly.
Perhaps it's better if you read it with some of Rousseau's books. To put it in it's philosphical context.
A better book on philosophy would be Zen and the art of motorcycle maintainence. Easily one of the best books I've read. And the rethoric in it is actually interesting in contrast to Candide.
Perhaps it would be interesting to make a "book unsuggestion" list instead. A list of books you've read that you though were good but didn't deliver. (Books read for school summer reading don't count.;-)
An unmanned maglev has sped to a new world record of more than 550 kph, topping the speed record for conventional trains held by the French TGV, which hit 515 kph in 1990.
It uses Direct3D (and OpenGL) to display graphics. This is something you would use in case you didn't want to build your own game engine. (Which is quite a lot of work, or so I've been told.;-)
It can use a veriety of different other libraries as well.
Judging from screen shots and feature lists it's pretty much on par with Crystal Space. Although the latter doesn't have built in support for Q3A levels. (Would have been a nice way to compare them otherwise.)
I do know that some game engine courses at my uni use Crystal Space as the engine of choice. (But I haven't taken that course yet.) Seems like lot's of fun in any case.
AFAIK the file format ".avi" can wrap any other encoding format. That's why most DiVX versions (Which are basically MPEG-4.) use the.avi extention.
If you are searching for "pure" MPEG-4 codecs for your computer I'm not sure where to find them. But I think the latest DiVX version are pretty much standard MPEG-4.
Strange, it would seem to me that a "straight" PVR version would have been more successful than any of those. (Both can play MP3 and MPEG-4 video. The first is small and the second is a "jukebox" version with 10GB HD.)
I'd love to put something like this next to my TV and use it to play stuff I find online. But it doesn't seem like it will be very good for that purpose. (The big one can be used as a PVR, but no networking built in.)
Just seems strange that they haven't targetted the most obvious market instead of to rather fringe ones.
I use them all the time. I find a lot of nice sites which I can't remember the URLs for. And I seldom can find them again using Google. (I've tried in some cases when I've lost my bookmarks file.)
Actually I'd want a better bookmarking feature, or a cross between bookmarks and History. To make sure that I can easily find pages where I've been.
The boot encryption block is really there in order to let Microsoft control which games are available for their console. They are more interested in getting money from producers of games than from stopping you from playing a non-licenced game. Naturally if everyone were to play using hacked machines than that would be bad for Microsoft, and so they added the encryption/authentication to stop that from happening.
Naturally stuff like this will undoubtedly pave the way for "X-Box" demo's within the demo scene. That would rock! (Because those guys can really do some neat stuff.)
And from his (The guy who wrote the paper.) website it's clear that he has contacted Microsoft and he has been given a go ahead on publishing the paper. So it's unlikely that it will be "foxed" at least at this stage.
A lot of people seem to belive that it's about network security. It is about hacking the boot procedure for the X-Box. This can be grasped just by reading the abstract to the paper.
Abstract
This paper discusses the hardware foundations of the cryptosystem employed by the Xbox TM video game console from Microsoft. A secret boot block over-lay is buried within a system ASIC. This secret boot block decrypts and verifies portions of an external FLASH-type ROM. The presence of the secret boot block is camouflaged by a decoy boot block in the external ROM. The code contained within the secret boot block is transferred to the CPU in the clear over a set of high-speed busses where it can be extracted using simple custom hardware. The paper concludes with recommendations for improving the Xbox security system. One lesson of this study is that the use of a high-performance bus alone is not a sufficient security measure, given the advent of inexpensive, fast rapid prototyping services and high-performance FPGAs.
So no need to worry about DDoS or lost savegames. This is about playing unauthorized games, making a DiVX player etc.
Seems from posts above (Namely a guy who joined the GNU project in ~88.) that this is completely bollox. When he joined he suggested that he should work on a kernel (This was before Linux.) but RMS told him that. "No, someone will make their kernel open eventually. It's better to do userland stuff." So he did a Fortran77 compiler instead.
And I trust that guy a lot more.
What did get RMS "annoyed" was that everyone was saying how great Linux was. When in actuality the majority of the system was GNU. (Compiler, libraries, utilities etc.)
Praytell, exactly what architectural features (technical reason, please) does Hurd have that allow it to allow users to mount encrypted filesystems?
Because they all run in user space. You can write your own FS and mount it in. Even if you're not root on that machine. You can't do that on "normal" Unixes for a number of reasons. Mainly because if it crashes it brings down the system. (Or it can.)
Really, Hurd is a really cool project. If you're into OS development at all you should take a good look at it. (At least the theory behind it.)
I have not done any in depth analysis of OSX, but from what I've gathered it's not really as "new" as what they are trying to do with HURD. It's more of a standard Unix put on top of a micro kernel. Not that this is a bad idea, but it's not the same thing.
I bet that Apple having more resources is a big thing though. If you want to get hard things done I find face to face communication irreplacable. Not that it's imposssible to do over the net, but it is harder. (If for no other reason than that the lag in the discussion will be orders of magnitudes longer.)
Personally I think it's a combination of all of these factors. Hard problem, not optimal way to organize people (Better than nothing though, of course.) and not as much resources. (I bet Apple can pay up for some serious simulation tools for instance, that makes tracing odd behaviour a lot easier.)
From what I've heard Stallman say during one of his speeches they had a lot of problems debugging it. Normally debugging an OS is a real pain. Debugging a multi threaded one is really a pain.
When comparing it to Linux you should also take into consideration that Hurd has a lot of new ideas to implement. That means new pitfalls to fall in. Linux is pretty much based on "stuff that works" which makes it easier to get working. (Not that I want to belittle Linus' and the core teams effort.)
Another reason is probably that since Linux showed up they have put more effort into other more "critical" projects. Hurd has more features to make it attractive to fast computers, when you can afford to waste some cycles for features/security. That has not been the case for all that long.
I'm in a similar situation, except that I go to college. What I've noticed is that it's probably not the keyboard per se which is helping me from pains, but secondary effects from it.
At my desk at home I have my primary monitor put into a corner on the desk. (The desk is curved, and it's intended that the monitor be placed like this.) However since the monitor is quite deep, I still wouldn't have space to rest my entire arms in front of the keyboard, if I had a normal one. Since I have a "natural" keyboard however I can rest my arms at the sides of the desk instead. This means that I can keep my elbows resting at all times comfortably.
I think this is the key to the posture at my desk. In school I can rarely do this. (And since I seldom use the exact same workstation there is little I can do about it.) It is also at school where I have gotten pains in arms and back from working too long. (I frequently use a computer much more at home, with no pains at all.)
So now I always tell people that complain that they should make sure that they can rest their arms in front of the keyboard. If they can't they should reorient their monitor/keyboard so that they can. (By placing it at a short side of the desk for instance.)
Precisely, instead of having the specific series for 10 seasons (there's seldom material for more than a few anyways) they should start again. Instead of following a specific series or specific characters you can watch series dependent on who wrote the story, who directed/produced it etc.
And I've only watched the first 4 seasons or so of X-Files. After that every ep felt like "I've already seen this." so I stopped watching. (There are some good X-File stories still though, unfortunately I only rarely see them.)
The only series which I can think of which I liked all the seasons of is Seinfeld.
You should check out "Farscape" which is a good Sci-Fi series. They have some serious story stuff going on there as well, several episodes are 3 parters, which makes for basically a movie of time. (Generally it's not as high tempo as a movie though.)
As they comment in one episode of Futurama: "You know that at the end of show everything will be the same." Because that way you don't confuse people who miss a few episodes.
I've heard that the show "24" is supposed to be good as well, haven't seen it yet though.
Really, what anime series mainly benefit from is that they have a clear story from beginning to end. They know how many episodes they want to cram it into. That way it makes it easier to make a coherent story out of it. More shows should be made on that premice and we'd have a lot more stuff worth watching.

Please mail me if you do.
Lila just happend to be on *my* "to read this summer list". :-) But thanks for the tip anyways.

Wouldn't be much point in the project if you had to pay more for the chip than for a new super computer, would it?

Treat the wireless network as the Internet. Firewall it, don't trust host on it etc.
User loggin on from the wireless net should use VPN.
That way you're safe.
Send it in as a Slashdot poll! (I think you do it like when you send in a story, but with POLL in the headers somewhere.)
;-)
Oh yeah, and add an alternative about having Cowboy Neal doing your typing for you.

Lot's better to just do it on your workstation.
