Comment the CO2 improvements are minor at best (Score 1) 46

Diesel engines emit 15-20% more CO2 per unit volume (liter/gallon) of fuel burned because the fuel contains more energy/carbon.

And once the companies stop cheating, the fuel economy of the Diesel just isn't all that much better than a turbo gas engine.

Why put up with extra NOx and particulates (depending on the car you compare to) to save such a small amount of CO2? Just get a gas hybrid and do better all around. Or a plug-in hybrid like the Volt where you can do most of your driving burning no liquid fuel at all?

Comment reports are it's no fix (Score 1) 46

That the cars will still emit 200% of legally mandated NOx levels.


Only the newest vehicles with the urea injection (2015 and newer) will make it to the legal levels.

So if you bought a "clean Diesel" based upon VW's bogus claims, remember what they did to you next time you're out buying.

Comment It's not just facts (Score 1) 150

It is an expression of them.

You cannot prevent distribution of the facts. That's why I said he should make his own representation of the facts and distribute that.

But you don't have a clear cut right to redistribute someone else's copyrighted expression of the information.

I've seen his videos, he only shows a small section of the schematic. He should just redraw that section himself and use that in his video. It's easy.

Comment it can't be for distributing copyrighted materials (Score 2, Insightful) 150

This guy has a massive pariah complex, and great job feeding it, slashdot.

It appears the guy is using Apple-copyrighted schematics. If he wants his youtube videos to stay up it's really simple to just not put them in the video. Just draw your own representation of the part of the circuit you are working on and put that up.

No, not every advanced nation has an electric grid for its trains except the US.

Sure, there are many electric trains, even freight trains. But many countries still move friend with diesel-electric locomotives. That includes every country in North and South America, India, China, Australia and many many more.

It is disappointing the US doesn't have more electrified passenger rail.

Comment there are hybrid locomotives (Score 1) 106

The problem is where to put the energy. The amount of energy recovered from a large train is just too large to store. So hybrid locomotives are used for switching, where the amount of energy is smaller.

Trains don't need additional power to climb grades, they just slow down. To go the same speed would requires not just more energy (fuel or electricity input) but more powerful electric motors to turn that energy into torque. And they just don't have those bigger motors. If they did, they'd just bring along a bigger generator and then again still have no need for the electrical input. Because in a freight train a lot of the ability to put down power relates to the weight of the locomotive, as more weight means more friction on the rails. So if you're going to make the locomotive heavier, why not just do it with more fuel, more prime mover and more generator?

Passenger trains usually hail the same cars every day. So those cars can have the motors in them and the locomotive (if present) just converts fuel to electricity. In that case, you have enough grip and power already, so removing the prime mover and generator can make it a lot more efficient. But since freight trains just drag different collections of cars each day, it has to do all the work.

Comment It doesn't matter that it's burned in (Score 1) 124

The key is burned into the processor, but you can employ the key in the processor to decrypt it. Just as the boot code decrypts the kernel cache, you can use the hardware to decrypt it for your own nefarious ends.

It just means you have to do the decryption on the device.

So the original writer was correct in that this encryption didn't stop all observers, just casual ones. Anyone who could get a significant jailbreak on a device could decrypt the kernel caches.

Comment yes, that's correct (Score 1) 238

It allows them to sell their car for $7500 more without suffering the reduction in sales that would come with the customer paying $7500 more.

That's a subsidy to Tesla.

What did you think it is? The point of the program is to increase EV adoption by making the cars cheaper to acquire. How could you not see that as a subsidy benefiting Tesla (or any EV seller)?

Comment No, there's no difference. (Score 1) 229

A VPN is a tunneling service. Same thing. Both make your packets originate from somewhere else, and that's why geolocation doesn't work. That's why they block those.

I don't know what you mean by "read the article". I read the slashdot summary. And it doesn't match up with what is actually in the source material. The source material says the problem is due to using HE's VPN.

BTW, I'm a user on an ISP with native IPv6 and I don't have problems connecting and watching shows.

Comment this kind of thing is usually a DDoS (Score 3, Interesting) 91

When companies have outages like this and don't want to talk about it it's usually a DDoS.

They don't want to brag they can be DDoSed nor do they want to help pump up the group who did it. They don't want to give any info which is feedback about how well it worked either so the attackers can tune their attacks or gauge their chance of success if it was a dry run.
