OFDM which is used in 802.16 is much better for multipath and ISI, since it uses a large number of carriers sending data at a lower rate. Think of it sort of like a slow parallel link, instead of a very rapid serial one. Since the symbol rate is much less, the different path delays which cause multipath interference have less effect in the same way jitter is more noticable with a higher clock rate.
I agree - Darl McBride would probably advise you to threaten and sue them if they even think of looking at a competitor! Look how well it works for him. Actually, I think he studied customer relations under Al Capone and John Gotti.
This kind of reminds me of that scene in "The world according to Garp" where Garp and his wife are just about to purchase a home, when a plane crashes into it. He immediately signs the contract, saying that it couldn't possibly happen twice.
Just think, the chinese guy might well have earned history's first Darwin award, had they existed at the time.

Prof. Picard was nearly killed in his balloon contraption as well. Many considered him a nut when he went up, and figured he would never come back alive.

About a microloan program, where very small loans would be given to poor individuals in remote areas, who wanted to start their own businesses. One woman in a remote village used such a loan to buy a cell phone. Prior to this, there were no phone service at all. She would charge her neigbours to place calls using the phone, hence becaming the defacto phone company.
I wonder if there would be an aftermarket beefing up the motor, sort of like how the old beetle could take a 911 motor. There would be something unique in driving a vehicle looks like a tiny gnat on the road, but can fly like a bat out of hell.
Good reasons for using 4/8/16 bit SOC controllers:

32-bit Processors, Cheap
·
· Score: 3, Informative
1) High code density: Even if you need more instructions to perform an operation, if the instructions are only 8 or 16 bits wide, you wind up with a smaller executable. Hence, you need fewer bytes of ROM to store the firmware. And if a lot of your data is byte sized anyway, (processing strings, or reading an 8 bit ADC or setting an 8 bit PWM) the code may be smaller still, since there is no byte packing/unpacking into a 32 bit space required. (Incidentally, this is a major problem with 64 bit and VLIW computing.)
2) Power consumption. An 8 bit processor has only 25% the bus width of a 32 bit processor. Registers, instruction decoders, and ALU are 25% as complex. Ergo, for the same manufacturing process and clock rate, an 8 bit core will always consume a lot less power. If you are trying to run an algorithm off a watch battery, this really matters. That is chiefly why the venerable 8 bit PIC with its horrid assembly code, continues to be popular.
3) Less die space. Same reasoning as above. if you are doing an ASIC and can get away with an an onboard 8 bit controller core, why would you waste silicon using 32 bits?
3) Backwards compatability, ability to run legacy code. Even in embedded systems, stuff gets reused. 95% of you will be reading this on an x86 PCm which happens to trace back to a 4.7 MHz 8 bit ancestor found in the original IBM PC, the 8088.
What it ultimately boils down to, is selecting the right tool for the job. And there will always be a niche somewhere for humble little lightweight 4 and 8 bit controllers.

Unfortunately, that is the idea behind "trusted" computing. You no longer have full control over your own machine, you can only run applications "trusted" by those controlling the DRM. As soon as you run an untrusted app, you cannot run a trusted application. Typically, in this case the trusted app would be a DRM compliant browser. Attempt to fire up mozilla or anything that can otherwise image the data (even from a screenshot) and the it will not be allowed to run, or if it does the trusted apps will immediately shut down. At least in theory, that is how it is supposed to work.
Of course, nothing would stop you from capturing the screen from a camera on a second PC synchronized to the frame rate. It just makes things awkward.
MS cannot afford to ignore the threat. This will begin to drive down the cost of their software and erode their margins for any major country, not just in developing countries. If AT&T can threaten to switch and get a major price break, so could every other major corporation.
The days of unrestricted margin on prices appear to be over. MS will finally have to deliver real value for the dollar.
IANAL either, but it was told to me by one during a class on contract law. At least in this country, minors cannot be held to a contract, even if signed and witnessed. To the best of my knowledge, EULAs and minors are uncharted legal waters.
Pay to have a 12 year old purchase and install the software on their own PC, and leave the room while they do it. (They are the ones who will be playing the game anyway) Minors cannot be legally bound to any contract.
A quote from a German Colonel made during operation Barbarossa:
"The German Army in fighting Russia is like an elephant attacking a host of ants. The elephant will kill thousands, perhaps even millions, of ants, but in the end their numbers will overcome him and he will be eaten to the bone."
So it is with the *AA. Eventually they will fail out of the sheer weight of numbers they are fighting.
Anti-piracy sabotoge has been around for a long time - it dates back to the days of some manufacturers using 5.25 inch floppies that included an unused disk track containing sandpaper - attempting to copy the master disk would result in moving the floppy read head over the sandpaper covered track, thus destroying it.
This was stopped for probably the same reasons as discussed in the home security thread regarding booby traps. Destroying somebody's PC is illegal, even if they are making illegal copies of your software. Besides, what if they were using somebody else's PC to do it? And who would want to purchase a product that could destroy your PC if you make a mistake? Kind of like purchasing a car with a built in self-destruct as an anti-theft device. God help you if it malfunctions.
What about Voyager 1? It is now further from the earth than Pioneer 10, (it was launched later, but catapulted out of solar system at a greater velocity) Is it showing the same mysterious behavior?
I really wish these articles would contain a bit more meat on the bones, or at least link to something that does.
But only for a limited time. Nobody is superman. Run your cars engine RPMs well into the red for a few minutes every now and then, and no problem. Do it on a continual basis, your car will probably blow a gasket. It may take weeks or months, but almost certainly it will happen.
These guys are fooling themselves, just like the smoker who thinks they have indestructible lungs because they personally haven't died from any smoking related illness. It is always the other guy who is weak. It won't happen to me. Until the day it does happen to you, and by then it is probably too late. One day in all likelihood they will be found dead behind their desk with a stroke or coronary, or suffer a catastrophic mental breakdown. I remember reading the story of a VP who regularly pulled 100+ hour weeks, until one day he can into work and found he suddenly couldn't function anymore.
You can function on afterburners for a period of a few days or weeks even, but after that, you are fooling yourself. I have been on a couple of death march projects, and survived with sanity intact, but it isn't fun.
The article doesn't mention. I imagine the winner will now gain some notoriety of his own, short of like Capt. Brown after allegedly shooting down the red baron, Lothar Von Richtoven.
Of course, if you really want to make the local insect life happy you can always stand naked at night in a mosquito infested swamp, and/or arrange to have your body left to putrify and rot in a field after you die so the bugs can feast and pupate on your earthly remains. I wonder why PETA isn't suggesting this as a natural alternative to cremation or burial?
But seriously, if we could ever develop a nano-bug that dines on mosquitoes it would be a great day for mankind. Bye bye malaria!

I wouldn't mind if they left off the region codes while they were at it.

They seem pretty popular - I am watching a back to back CSI labour day marathon on Spike.
I heard enrollment in forensics college courses is way up on account of that program.
