The short answer is no.
If you want to see what is involved in making this work, take a look
at the bootloaders for Linux VR and NetBSD/hpcmips, and in how the
link address and memory maps of the respective kernels differ from the
default Linux and NetBSD ones.
All the earlier WinCE machines had mask ROM, so you had to be able to
load on top of CE.
Linux VR looks like it can use the bootloader from NetBSD/hpcmips, so
you could just port that one to the SA-1110.

The NetBSD port is being written to work the same way as Linux for the
iPaq.

Tesla was not an englishman. He was european (I forget the country, and because I RESPECT my facts, I won't guess as to which) but gained American citizinship. And he did not try and pass off anyone's ideas for himself. Marconi tried to pass off Tesla's ideas as his own. When Marconi made the trans-atlantic signal, he was using 14 devices designed and pattented by Tesla, produced by Westinghouse. Tesla demonstrated radio transmission several years before Marconi, and unlike Marconi, actually knew what was going on.
People have been suggesting this for ages. I've heard people call this idea a hampster vr, or a bi directional treadmill. For your own home vr stuff, a plain old treadmill would be pretty cool. There are actually systems designed around that idea. Lots of ppl have suggested a hampster ball, just no one has built one as far as I know. If they build it its an engineering/programming feat, but not innovative.
Ohh comon, somone moderate this up, my office mates are looking at me for laughing so hard! I like this comment!
isn't text graphical......

Is UNIX An OS?

Seriouly. Text is graphical. Look at punch card and teletype based machines. A computer with a command line on a monitor (not a typerwriter...well hell even a typewriter) gives a user a visual representation of the data there giving the computer, and the data they are getting from it. Have you seen the output from a punch card computer? Half the time it takes longer to decode the result than it would to write the program in a command line driven os.
Besides, what would the origonal mac-week guy say about batch processing operating systems? An os does not have to be as interactive as what were used to. Look at mainframes....there not going away (despite what we keep hearing)
Every public library I have ever been in has a subscription to either or both playboy and penthouse. Funded with public money. Anyway the issue isn't keep kiddies from viewing pornograpy, its about censorship. Blocking software improperly blocks many many other things than porn, even when there not supposed to. Look at peacefire.org for info on that..but then again, almost anyone reading this sotry has probably read that site at length already. IMHO the only reason that the legeslature is trying this, is because its high profile. These are the same people who probably didn't care about logging in national forests, but were up in arms over flag burning.
I'm not sure if they have this in Europe..but at both of the universites I went to (Iowa State and Purdue University) there was a surplus shop or warehouse. At these, they sold old equipment parts and supplies of every description. For instance I have two dec stations, compleet with monitors keybaords and mice that I picked up for $35 a peice. I always seemed to miss the x-terms though, they go FAST! Anyways I was able to pick up all sorts of hardware there, 386's and non functioning workstations and macintoshes are great sources for scsi hard drives, token ring cards, old memory (great for use in upgrading printers and other small devices) monitors, printers, all that stuff. If you can find these sales, go to them...there like ham-fests, only better equipment and cheaper!
Just my 2 cents.
Ok ok so its been so long since I"ve written a pthread that I forget the exact commands to start one.
Anyway asside from the kernel space vs disk space issue, Apache is still forked and not threadded. Threads are sometimes described as lightweight processes, and as anyone who has played with threadded programming vs forked programming (just because they got a new smp box and were bored one night) will find that threads do indeed take FAR fewer resources than forks. I don't have my pthreads book with me here at work (Get the oreily book, the online faqs and tutorials don't quite cut it) I recall the explanation that performance would very from system to system, but 10 threads should use about the same resources as 6 forks in linux.
Of course the advantage to forking is that you can kill a rogue fork, a stuck fork, or a hacked fork in the case of a forked server, without any special tools other than su.
Still, I think a threadded version of apache would be good
Oops, forgot to put the point to all that.
The blackbox idea in comptuer terms is far older than the next cube is what I was saying. The next cube was just a cool play on words with an 0'40 processor!
*thinks*
or was it an 0'30?
Next cubes? I always thought that the idea behind designing the cube was the black box idea. It was a play on words....made into a computer.
I'm not positive, but pretty sure that if the machine was deigned on that basis, you coudln't sue over it, the phrase is in the public domain. Its like somone making and marketing glass hearts with cracks down the middle (broken heart) and then trying to sue anyone who makes any heart-shaped glass object with a flaw afterwards.
In leu of last weeks 3d printer article, how about some desktop fabrication appliences? I'm sure a 3dprinter is way to expensive...
but I was looking up desktop CNC mills after reading that article, and you can get some for about 1200-1600 that will work on plastics and light metals. Make your own coffe cup with it, maybe your very own star-wars models (from the real movies, not this episode one crap).
What would be a better gift for the creative geek?
When some of the first computing patents started going through, they relized that alot of their ideas were previously patented, or partially in some cases by a certain mr Nicola Tesla. This is reportedly where the precident started to only looking back a hundred years or so for patents. IMHO they should revoke all patents and go back through them one by one, beacuse they'd end up finding that half the pantents in the past 10 years are probably invalid due to either prior use or even prior patent. But then again the government doens't ask me;)
As some of you out there know, there are some bands that have the community of their fans close to their heart. The best examples are probably the Greatfull Dead (Now the Other Ones) followed closely by Phish. Both of these bands are gracious enough to allow (and encourage) fans at concerts to tape the shows, and trade tapes. As Jerry Garcia wanted, none of these tapes are for sale, simply traded and copied. Many of these recordings have made their way to mp3s, and if your a true fan of thier music, youll quickly realize that while the audio quality isn't the best, the performance quality of both these bands live far outweighs that.
Ohh and a blatent plea, the cd that I had 5 years worth of Greatfull Dead concerts on recently quit working on me. Anyone have mid to late 70's GD mp3s? e-mail me, I miss my music.

Don't list all the sites they can't get access to...just list the sites they CAN get access to. I know this is REALLY clunky. but it would work. All of the.edu and.gov sites should be ok. Then probably most of the.org sites. If you really want to keep them from getting at porn or other obscene material, make SURE you ban all chat rooms.

now that was a great site.
