I'll promote to everyone in Vancouver that the BIG earthquake is coming real soon now (i promise! see the scientist said this! oh don't read what they said 30 years ago!) and they should sell their house to me for a lot less than the current average fixer-upper house price of $650,000.00 ! Or I could take it off their hands without charging them at all!
BTW the last earthquake in Seattle affected the interior of BC. A VERY BIG EARTHQUAKE like the one being discussed would cause damage all through the Interior and Okanagan as well.
Maybe I should move even further away, like Whitehorse or New Orleans... Then I'd be very safe from earthquakes!
My point though is that people were being irrational and lived in a different place for 30 years just because of the fear of a possible earthquake represented by some expert which never happened.
To provide sufficient server and networking capacity, the Autopilot Hardware team is involved in Data Center planning, new hardware expirementation including SSD and ARM
While MISRA is a good informal collection of C and C++ programming guidelines for safety critical devices, it is by no means the only thing can can be or should be done.
Toyota does do a lot of testing and re-testing and certification and takes a lot of time and money to do this.
There is a lot more scrutiny on software systems for airplanes then there is for automobiles.
I believe that more people per year are potentially affected by software in automobiles than they are by software in airplanes.
Yes, there can be no "meta-theory" of all algorithms in general.
But if you restrict your implementation of an algorithm to a minimal subset of a turing machine, then you can make an algorithm for analyzing it.
However the minimal subset may be not useful for the task at hand. And the programmers would cry because they couldn't just use visual studio to drag and drop their C code....

The mechanic could not find anything; Now I don't have that car - If I did it would be recalled now because apparently it is more complex to fix than a mechanic can do!
The fact that accelerators get stuck is a normal part of operating a car.
Interesting to note that my current Toyota is not part of the recall; For whatever case this problem has been a design fault of specific models of the cars for more than 5 years and they still haven't completely figured out why! Is a sticking mat or sticky pedal so hard to diagnose? --jeffk++
I have seen nothing in any of the reports that talked about any computer system malfunction. All reports of malfunctions were mechanical: mats and stuck pedals.
As a consumer, if there was no regulation, then I would want to be able to know what testing was done on the software of a safety critical component. They tell me all about the impact resistance of the frame and do all sorts of crash tests of the car and make that public; why not the software/firmware/hardware?
I used to own a 2005 Matrix! I noticed this problem, but just like everyone else, I thought it was a sticking mat. But then I realized that the mat was not in the car!!! So I thought it must have been a sticky pedal.
Interesting; The Motorola RaZR (pile of crap) didn't let me. I think my carrier disabled that feature - they had also disabled the ability for it to import ring tones via USB requiring me to pay through the nose to download it via the cell network.
Well that blows a hole in that idea, then! What could this guy have done in this situation? He can't un-press the gas, he can't press the brake because the CPU gives the gas precedence if you press both, the emergency brake would cause him to go out of control, and he can't shift gears because that is under software control too!!
Isn't the development cost spread out across the number of objects that are sold? Aren't there a lot more Toyota's sold compared to any type of Helicopter or Boeing Jet? How much does this Toyota Recall cost Toyota? How much will the upcoming lawsuits against Toyota because of the accidents caused by this cost them? How much would it have cost Toyota to do their homework beforehand? It really does come down to money, of course! It is cheaper to spend more money to make sure your products don't kill people.
The need for ECC memory due to poor multi-layer PCB impedance control during manufacture
The 387SX that I used to have that told me "2.0 + 3.0 = 4.0" because the motherboard had the wrong wait states hardwired
The laptop that I had that was designed before 3 chip 1 MB SIMM's and caused improper memory refresh on them causing windows and linux to crash intermittently when using high memory
The reality is that both computers and software are ultimately designed and verified by people. People screw up. Therefore computers and software can be buggy. So you need to make sure your system can manage under these conditions.
Now is the time for people to study the comp.risks forum.

Is it a fact that many physics theories are misrepresented as fact?
I don't believe it.
Your statement is based on a belief that his mum is still alive.
Perhaps you meant to use past tense form?
Btw how many physics theories are misrepresented as fact?

Hey, on second thought this is a great idea!

Yes, the earthquake is going to happen, you can be 100% sure of that.
Now what is the chance that it will happen in the next 30 years? That is most definitely not 100%! So is that chance greater than death by accident?
Perhaps they would be better off quitting smoking if they were so scared of dying.
--jeffk++
Yes, of course, I agree.
My point though is that people were being irrational and lived in a different place for 30 years just because of the fear of a possible earthquake represented by some expert which never happened.
--jeffk++
I've met people 20 years ago who moved away from Vancouver in 1980 because they were scared of the big earthquake that will come ANY DAY NOW!
There is probably more chance to get hit by a drunk driver when you are walking down the road where they moved to.

Apparently though, they have a history of retroactively changing pricing structures and demanding retroactive payments.
Can you trust them?
Just like Exxon was!

--jeffk++
We'll see what Toyota comes up with. They just announced today a fix for the stick gas pedal but do not have a fix for the floor mat.
That is really confusing to me; wouldn't it be simpler to fix the floor mat?
--jeffk++
From the Washington Post: Toyota did not install brake override systems despite complaints
From the news sources... Also one of the very first comments on this topic: Also, they couldn't put it into neutral because it had a push-button shifter as well

You haven't been looking, then:
Is there evidence of a problem?
