Comment Re:A very "someone" (Score 1) 618

The trick is to find the ~5% who are doing something different, so they'll get different results, and help them.

Or in this case, we're talking about the people who will continue doing OK like previously because they were doing find until some kind of accident happened. But even otherwise if you could know (which I know isn't easy) that giving someone $1000 every year would prevent that person from being homeless, it's still a worthwhile investment even if you don't care about people's well-being.

Comment Re:MPG savings (Score 1) 290

Back of the envelope estimation here... the mirrors are probably 1% of the drag cross section of the car and the drag is maybe ~50% of the total energy loss in the car. So my guess would be around 0.5% reduction in fuel consumption. Over its life, your car might burn about 20,000 liters of gas, so you'd save about 100 liters, or about $100 (depending on exact prices). Of course, I'm likely to be off by more than a factor of two (but probably less than a factor of 10).

Comment Re:Can Linux be used in automatic cars (Score 1) 220

If Windows software makes a mistake, I assume Microsoft can be sued. Like Toyota has been sued.

If Windows running in a Toyota kills someone, Toyota gets sued, not Microsoft. Microsoft makes it clear that their software is not to be used in a mission-critical application. Same goes for Linux or other software. Whoever makes it part of some device is responsible, at least unless the software manufacturer explicitly provides a warranty for that particular application.

Hardware analogy: if Boeing uses screws from Home Depot to build an airplane, who do you sue when the plane crashes? Home Depot or Boeing?

Comment Re:EVs aren't that much better (Score 1) 630

Your analysis is valid (assuming the input values are correct) assuming that your car is going 80-100 km/h at constant speed. The huge advantage of EV over ICE is when you're stuck in traffic going 0-10 km/h and stopping frequently. In that case, the EV efficiency can even go up (if you have regenerative braking), while the ICE efficiency goes to near zero since the engine's idle.

Oh, I totally agree here. I also assume he did a little more digging than just typing HELP. Things like trying the commands listed in the HELP to see what they do and/or trying some variants. Again, entirely reasonable things to do, no matter what the author thinks or likes. The vast majority of reverse engineering techniques are still legal (as it should be).

Andrew did not reverse-engineer the Bitkeeper transfer protocol. What Andrew did was to telnet to the Bitkeeper's server port, and type "HELP". Bitkeeper then obligingly told Andrew what its commands were, in the exact style used by all early TCP daemons like FTP, SMTP, etc.

I believe trying commands to see what they do is still called "reverse engineering", despite being ethical, legal and not involving any decompiling.
