I beleive TORNADO is just a GUI built on top of GDB, so much of the Wind River toolchain is no better than it's Open Source foundation. The real value that Wind River is adding here is in BSP support for specific processors -- meaning their should be a real market out there for consultants capable of porting Embedded Linux to customer specified hardware.
oes embedded Linux have any advantages whatsoever over say QNX or TRON?Yes, it's a heck of a lot easier to port Open Source applications to, so you don't have to write all your code from scratch. Also, it's oriented towards protected address spaces for each process, unlike vxWorks or pSOS. On the down side, most people consider it to have a larger memory footprint -- but then, memory is cheap and getting cheaper (that's what keeps Microsoft in business!)
My mistake (didn't RTFA). All they are talking about is not letting buffers overrun all the way into code space. This still doesn't prevent you from corrupting data, or overwritting the return address on the stack with another address. In other words, it's still no silver bullet.
Since you have to rewrite the software anyway to tell the hardware what the buffer boundaries are, this doesn't sound like any security improvement over just rewritting the software. Only improvement is that checking bounds is a little faster.
In ultramarathons, e.g. 100-mile races, women do better than men. Granted, these are women with less that 1% body fat, but since women burn energy more efficiently and have slower metabolisms, they do better in ultra-endurance sports. In the context of a marathon, having longer legs probably outweighs the benefits of more efficient metabolism -- but then, I'm no expert.
"On the internet, knowbody knows you're a dog." If I can't tell the gender of the people I'm playing against, what difference does it make? Sure, people that self-identify as female get treated different in role playing games, but half the people are misidentifying themselves anyway. In FPS games, gender doesn't seem to make any difference -- you frag your enemies and cover your friends. If they really obeyed the laws of physic, smaller players would be harder to shoot, but I don't know of any games that actually do this. Maybe it's different face to face, but I've played at gaming centers against people in the same room and still didn't know which of them was in the game with me. (By the way, it was the first time I'd ever played against humans and I got my ass handed to me on a platter.)
You can run different channels spaced far enough apart that they don't interfere, but yes, under clustering all the channels would saturate long before you reached 1000 laptops. You might be able to get away with something non-network intensive like SETI@home.
My point was that the Grateful Dead managed to be the most profitable band in the world one year while still permitting their music to be freely recorded and traded. My joke was that Jerry Garcia and Bill Graham are dead now. (I once ushered a Dead concert at Shoreline Amphitheater and committed the cardinal sin -- I demanded that Bill Graham show me his ticket! He just said "I work here" and pushed past me...)
IBM could have just demanded that everybody running Windows 3.0 obtain a license from IBM, because it is obviously a derivative of OS/2!!! It was that easy, and those morons at IBM didn't even think of it! What the hell were they thinking, they gave up the OS/2 market to Microsoft, and all they had to do was just sue Microsoft and every one of it's customers!
similar to (iii) any Code contained in or Method devised or developed in (iv) UNIX System V Sounds like a description of vxWorks or any of the other embedded OSes that pride themselves on being "just like Unix". As I read this, you now need an SCO license to run vxWorks... I wonder how Wind River feels about this? And isn't BSD pretty "simular to...UNIX System V" too? How Fortunate for Microsoft that they already bought their license to use BSD code...
is this another case of humanity losing advanced space travel capability due to neglect, like Apollo? No, it's more a case of not wanting to spend a lot of money exploring something that will never be of any use to us, ever. At least Mars still holds out the promise of potential human habitation. You do know why Bush wants to go to Mars, don't you? So that there will be a place to send "unlawful combatants" when Guantanamo Bay gets too full!
SCO offers at no extra charge to its existing Linux customers a SCO UNIX IP license for their use of prior SCO or Caldera distributions of Linux in binary format. Does that mean my $30 Caldera Linux Technology Demonstration boxed software is now worth $699?
Chicago rates have dropped 16 percent in the last three years. Correction: reported crimes have dropped 16 percent. Just like reported crimes in Atlanta went down in the years before the Olympics there. Funny how now we find out the cops were just fudging the reports... remember, when you report a rape of mugging, it's not really a rape or mugging until the investigator agrees with you that it's a rape or mugging.
My 2003 Honda security system works the same way; I can get into the car using the key, but the alarm goes off if I don't use the transmitter. In fact, if I stop the car, take the key out, open and close the door, and remain in the car, the alarm goes off after a minute. Likewise if I leave the trunk open too long. Damn annoying technology, if you ask me. Why can't the alarm just turn on when I tell it to, and then turn off when I tell it to?

Now tell me when are they going to start working on Defending Earth From Madmen With Asteroids?
Actually, if she is female and goes there, then there will be chick In order for there to be chicks, she would have to bring a friend...
Simple google search on "women" and "ultramaraton" returns this as the FIRST hit. Next time google before you flame.
Separation of programs into separate code and data segment -- what a novel idea! I hope they got a patent on this technology!

the pocket-protector Beowulf cluster!
Uh, The Grateful Dead and Bill Graham used to condone taping of concerts. But then, where are they now?
Why leave them in a room? Run 802.11g and use all the laptops while they are sitting on their owner's laps!
And another $699 'cause you've obviously been making prodigious use of "coke"!
What, you expect lawyers to know how to administer web servers?

Earth was destoried?!? When? I must have missed it... what did they do with Earth's story when they took it away?
