The problem is "a file" instead of being "My hundred page mortgage packet" is going to be superficially similar to the output of/dev/random. Its unlikely a judge could find anything worth enforcing in a big/dev/random file.
I don't agree. "A file" could be whatever you wanted it to be. "I'll sign all my possessions over to cbiltcliffe if he provides me with a single 1997 US nickel." Then, you add a serial number to the end of the document. The length of the serial number will depend on the hash being used:
MD5: 128 bit. SHA1: 160 bit.
By the time you've gone through all these serial numbers, you'll have your collision. If "a file" is in the format of a Word document, or some other such non-text format, you'll even be able to keep the serial number hidden, so the judge doesn't see it. Makes for less awkward questions that way.
Now, is it feasible to brute force through all these serial numbers to find your collision? Depends on the processing power you have at your disposal, and what hash you use. If you happen to run a significant botnet, the calculations would be somewhat trivial. If you're trying to do it on a single netbook, you're probably out of luck.
Traction control is irrelevant when trying to stop a vehicle. Stability could be a moderate issue, if the entire suspension goes horrendously sloppy at an inopportune moment, but even at that, you've still got the actual mechanical suspension, so it's not a big deal. If your ABS suddenly decides that the wheels are at imminent lockup at 0.1G deceleration on dry pavement, then you've got a problem. But that's what the emergency brake is for. It's still mechanical for that very reason, and I think is required to be by law.
Yes, motorcycles rev a lot higher. But that's not what I was talking about.
A lot of engines in North American passenger cars redline at 5,500 or 6,000 RPM. It doesn't give you high horsepower at high RPM, but it gives you gobs of torque right off idle. I happen to like the feel that the gobs of torque gives me a lot more than high RPM horsepower.
It also means that you can smoke the pimped out Honda in the next lane without warning them by having to rev your engine up before the light goes green. Not that I'd ever do such a thing, of course....
Since this article is about cars, not motorcycles, I figured it would be implicit that I was talking about car engines, not motorcycles.
You don't need a lot of torque to move 500 lbs of motorcycle and rider. 4000+ lbs of car, driver, passengers, cargo, etc, though, you do. And referring to Honda: that's exactly the type of engine I'm talking about. I've driven a couple of Honda cars, and a handful of Toyotas, too, and they're all the same. I find the lack of throttle response at the low end to be downright frightening. It's like you hit the accelerator and.....nothing. When you're used to 200 foot pounds at 1500 RPM, and climbing from there, this "nothing before 3500" thing is painful.
Try 1984 for multi-port and DIS on the turbo Regals.
Front drive Olds 98 came out in 1985. It had multi-port injection but still had a distributor.
1985. You're right. However, my parent's was an 86, and I'm sure it had electronic ignition, rather than distributor. Wasn't sure about the 3.8 Turbo Regal and Grand National, but 1984 is when they added the intercooler to the Grand National, isn't it? Doesn't surprise me that it would go all electronic at the same time.
Compare the result of a GPS device failing during this scenario vs. the ECU that controls ABS, stability programs, traction control, etc.
If you require ABS, stability programs and traction control to stop a car safely, even on a mountain road, you are an unsafe driver, and shouldn't be behind the wheel.
As for this:
Would you trust your family's life to a device that was manufactured to be sold for ~$150?
My car's brake pads are much, much more important for safety than ABS (considering it doesn't even have it), and they cost under $100.
While it's true that a lot of them are under the hood, most 2000-2005 GM models (maybe more years...don't know) are at the front left of the engine compartment. If the car is moving forward at all, then cool outside air will be blowing over it, rather than any engine heat. So while the average engine compartment temperature may be 50+ C, the actual location of the ECU will be significantly cooler.
Think about this: and engine at 8000rpm will complete one rotation in 7.5ms. So the better control you have over the injectors and spark plugs, the better fuel efficiency you can get from one burning cycle. While a diesel will probably not reach 8000rpm,
A decent gasoline engine won't reach 8000 RPM, either, unless you're one of those people that thinks a few more horsepower at insanely high RPM is worth having practically zero torque anywhere below 3500.
especially when wunderidiots like Chevrolet put the PCM under the hood.
Huh? Every GM I've ever looked at has the ECM under the dash. Not saying you're wrong, but what year/model are you referring to that has the computer under the hood?
Try 1986. That's when GM went FWD for most of their full size cars (My parent's Olds 98 among them) and the 3.8 V6 - while not officially called the 3800; that moniker came later, but it was basically the same engine - was all electronically controlled.
Maybe the GP is thinking the electronics kicked in with the xx00 naming scheme. Or maybe they've forgotten that the '3800' was previously the '3.8' and they couldn't find any information on Google older than the naming scheme introduction.
No to mention the fact that in pretty much any corporate culture, it's hundreds of times easier to get a PO from management for "Repairing $device_that_we_already_have" than it is to get one for "Purchasing $new_device_to_replace_old_device_that_we_already_have" regardless of the fact that said old device is broken.
in contrast very few 20 year old PCs are still in regular use, I think a lot of people would be very hard pressed to find a ten year old computer being used daily
I've got a 15 year old PC that's not only used daily, it runs 24/7 to run a specific piece of software. I've also got a 14 year old one that does some network functions, although it would be much easier to replace than the first one, if it came to it.
So, my anecdotal evidence trumps your statistics, because as everybody on/. knows, if you have a single contradictory outlier, it proves generally accepted trends are completely wrong.

But you're not dead yet, therefore more things are or have been alive than are or have been dead.
Dammit. Stupid HTML parsing.....
Last line should read:
death->ubiquity() < life->ubiquity()
It can't be less, either.
Yes it can, and it is.
Everything that's dead was once alive, therefore for the subset of living things that are currently dead:
death->ubiquity() == life->ubiquity()
However, for the subset of living things that are currently alive:
death->ubiquity() == 0
and
life->ubiquity() == earth->human_population() + earth->animal_population() + earth->everything_else_I_dont_feel_like_listing_population()
Therefore, for the total of all things alive on earth at one point in it's history:
death->ubiquity() ubiquity()
It's spelled "ka-ching".
Maybe the GP is Spanish....
So download it, and put it on your desktop.
Or hell...burn it to a CD at home, and keep it in your desk drawer at work.

Yeah...I maybe would have got that, if 128 wasn't _actually_ a "nice round number" in memory space....

I'm still wondering why we don't use high rpm small displacement engines in cars these days., apart from noise concerns.
Oil burning. The higher the RPM, the more oil is burned, and the more pollution by extension.
Besides, there are still people like me who like to be able to hit the gas at any RPM in any gear and know exactly how the car is going to respond.

The 15 year old PC I mentioned is a Pentium 75, with 48MB RAM, if I remember rightly. Runs NT4.

Your vehicle isn't a useless lump of metal and plastic if your GPS unit fails.
With most GPSs, no, the vehicle doesn't fail. But in a lot of cases, the driver might fit that description....
128 is a round number?
Maybe in memory sizes, but not clock speeds.
The media system actively affects the car's driving, too.
At least, if you're driving a thumpmobile.....

...you can induce ethanol content from the O2 sensor...
I think you mean deduce.
induce: cause to arise;
If your O2 sensor can cause ethanol to be added to your fuel, you've got more to worry about than emissions.
