Not sure what this says about the "Highway Patrol Officer"'s abilities as a driver. If he couldn't manage either of those then this new system won't save him.
This sort of technology already exists to an extent. TI's Hercules TMS570 microcontrollers have two CPUs that run in lockstep along with a bus comparison module. I think total fail-tolerance might take three CPUs....
This is just to detect when an individual CPU has failed. To build a fault-tolerant system you need multiple CPUs.
nb. The 'three CPUs' thing isn't done for detection of hardware faults it's for software faults. The idea is to get three different programmers to write three different programs with a specified output. You then compare the outputs of the programs and if one is different it's likely to be a bug.
Also this is exactly what chip makers already do to a great extent: the binning of CPUs by speeds is not a targeted process. You make a bunch of a chips, test them, and then sell them as whatever clock speed they are robustly stable at.
Nope. The markings on a chip do NOT necessarily indicate what the chip is capable of.
Chips are sorted by ability, yes, but many are deliberately downgraded to fill incoming orders for less powerful chips. Bits of them are disabled/underclocked even though they passed all stability tests simply because that's what the days incoming orders were for.
Make everybody Amish. You'll have less stress, you won't have to worry about gas prices and there won't be any technology for the filthy foreigners to steal.
Plus: In a couple of years their economy will be wrecked because you stopped buying their cheap exported crap. It's win-win.
Yep, did that too. It was a manual car and I got it in first gear before heaving on the handbrake (and you'd be surprised how little effect the engine has when you're going downhill towards a junction).
Yes, I would have slammed it into reverse if I actually got to the junction and somebody was coming the other way.
I've also got a car off a busy road by putting it in first gear and using the starter motor. You do what you have to do when you're in a pinch...
it will slow you down a LOT faster than just trying to engine brake.
Have you actually tried it in an emergency at highway speeds? I have. I assure you you'll have time to pray to several dozen deities before it actually stops the car.
Go ahead and try it next time you're cruising along. No, seriously. At best you'll get bad smell from the mechanism. It won't slow you down worth a damn.
While you're at it: Try stomping on the brakes when nobody else is around, just to see what happens. That way you'll know what to expect in a bad situation.
Beyond allowing you to perform a check of your vehicle's main systems remotely, mbrace2 technology can automatically make shit up about your car that is bad or potentially going bad, and before you even have a chance to think about the cost of the repair, they've already scheduled you for "maintenance" and charged your bank account for the appropriate deposit to order many, many "bad parts"...
Yep. No BMW mechanic would ever be able to figure out it was all lies and leak his findings to the press.
Compare to IE with 90%+ for the browser market, but that was beaten with the standards-supporting strategy.
Well.... 10% that and 90% not adding anything new to IE6 while the other browsers got so far ahead that even Joe Sixpack could see it was worth switching.

You can also put the car in neutral.

Get him an Arduino kit with lots of LEDs and servo motors and stuff.
The hardest part of learning to program is knowing what program you want to write. "Flash an LED" makes this a no-brainer.
He'll learn programming and plus a lot more besides...
It would be easy to write a program to brute force it...which would be a proof even if there's no fancy theory telling you why.
Nope. I wrote a program to edit the memory directly.
I know you are joking,
Um, no. I really did write programs in hexadecimal, on Z80 and 6502 (using Commodore PET hex monitor).
80 billion is a drop in the ocean compared to, say, USA military spending.
Plus... you actually get something in return.
"Assembler"? Luxury. We had to program our Z80s in hexadecimal.
The first episode of Mythbusters was the JATO rocket Chevy so viral videos aren't too far from their roots.
nb. The 'three CPUs' thing isn't done for detection of hardware faults it's for software faults.
...although it will detect non-catastrophic hardware faults as well, obviously.

Exchange of a defective item isn't the same as a "return".
Being able to return opened DVDs to the store is just asking for abuse. Unfortunately.
Maybe they could make it harder than just a phone call. Maybe you'd have to go to a phone store with some ID or something.
Gee, I sure hope they've thought of that...
For some reason they never have demo parties like this in North America. Why is that?
Americans don't do 'small' or 'compact'. 'Economical' can get you lynched in some parts.
If a program doesn't need a hardware upgrade to run it then it can't possibly be any good.

The problem is that the people who rob the people to pay for the alphabet soup agents get their info from the newspapers.
This just in: The USA has spies in other countries!

Stuff like this is called "learning to drive".
It's not a parking brake, never was. It's an emergency brake.
You know how I know you've never tried pulling that handle when the car is moving?
Me? I'd expect an 'emergency brake' to be a bit more effective then that...

Do you have any experience in this field that would justify your position?
I stopped reading at "sugar is a poison".
Without sugar you wouldn't be reading this.

It keeps them from being whistleblowers about things that aren't important.
What if we want whistleblowers for the things that *are* important? Like this one.
Or maybe you think torture works and is a perfectly acceptable way to get information?
