Except it's ok to carry more weight of batteries offset by less weight of engine (which was not taken in to account in the original comparison) Electric motors weigh a fraction what gasoline engines do, and take up a lot less space too.
50l of gasoline weighs 37.5 kg and contains about 475kwh (it's actually about 9500wh/l) add on the engine, about 400kg, and you're at 438kg for 475kwh, but can only extract 35% of that, or 166kwh. For an effective density of 400wh/kg
Meanwhile for electric, we carry 100kwh of battery weighing about 377 kg, but the motor only weighs about 30kg for a total of 407kg. At 95% efficient we are still at 95 kwh for an effective density of 233wh/kg
Cars are also already being shown off with 130kwh batteries and heigher coming all the time.
Yes, gasoline still wins the density contest, but not by orders of magnitude.
Modern electric cars travel almost as far on a charge as gasoline vehicles do on a tank, and only weigh marginally more. It's now in the realm of "good enough". The challenge now is cost, and infrastructure. While better energy density is still welcome, it will have negligible impact on adoption from this point.
Not realy a relevant comparison as we can't extract the energy from gasoline in a very efficient manner (best we can do is about 35% efficient compared to over 95% efficient for batteries) additionally electric motors are a lot smaller and lighter than gasoline engines.
If looking at it from a pure energy to move a vehicle vs weight to do so stand point, solid state batteries would be quite likely to tip the scales in favor of electric over gasoline.
Overall though, we're already past "good enough" for energy density in batteries. The challenges to electric vehicle adoption now are more in the charging infrastructure, recharge times, and cost of batteries. Density is just not an issue anymore (not saying more isn't better, of course it is, it's just not what limits electric vehicle adoption right now.)
My phone isn't rooted, but I still block ads. Sideload vanced from xda to get ad free YouTube, and background play. For the browser you can get ad blocking browsers, or add blockers that use a VPN. Personally I'm using my own VPN which blocks ads with DNS.
I used to root every time, but I got tired of the constant battle, and the big features I needed can now be done without it (ad blocking, and setting the phone to a reasonable resolution)
If you talk to my boss, being polite is the absolute most important part. Being right is irrelevant. I have been dragged in to his office a few times and chastised severely for messages far more polite than the one in the summary, not because they were wrong, but because they offended someone who thought they had a god given right to ignore company policy. I've been told the right answer is to respond in a way that is so watered down that you can no longer even discern my position on the matter (my boss has shown me how he would have rewritten my messages) And then, if the person decides they still want to go ahead, despite my objections (which they couldn't possibly be aware of) I should just do whatever they ask because they wouldn't have asked if they didn't know what they were doing.
(Yes, I desperately need to find a new job to get out of this department)
except at the usual reaction from the Canadian government is to do exactly anything that the US says. When they say jump, we ask how high?
which is sad, because this is a very transparent ploy to get Canada to buy more US equipment. It's well known that the US equipment manufacturers have put back doors into their equipment in the past, and yet the Chinese ones have never been caught doing so. So really which one should we trust?
I don't think the word omnivore means what you think it does... It doesn't mean we can choose to eat anything we like, it means we get our required nutrients from a variety of foods, INCLUDING meat.
Nuclear also has it's issues. A diesel electric sub is much quieter, and therefore harder to detect, than a nuclear as long as the diesel electric is running in electric mode. The trade-off is that when running the diesel it's much, much, louder, and the all electric range tends to be limited. Nuclear allows longer range and relative quiet, but not as quiet as electric.
This is interesting because it extends that electric range, and therefore extends the advantage over nuclear in short term engagements.
How stupid would a manufacturer have to be to provide the wrong password on the device? Just because they have to provide a non default password doesn't mean they need to write the wrong thing on the device. This is a solved problem by many, many, many, manufacturers already, they simply write a different password on every device they ship out. In this case the government isn't requiring anything that isn't already common practice. They're simply enforcing it on those who have lagged behind what is currently common industry practice.
There are other easy solutions to this as well, such as not having any password at all to start with, and prompting the user to generate one before the device connects to the internet.
This is a solved problem, devices like this usually have the password on the device for resetting. And before you talk about that being an attack vector for people with physical access, when you're talking home devices anyone having physical access to the device is a far larger problem than that.
Oddly enough, this was my first thought. Raspbian is the only thing I have that is internet connected, and comes with a default username and password, and worse yet, it neither prompts you to change it at first boot, nor provides a menu option to do so in it's configuration.
Sure, I know how to change a username and password from the command line in raspbian, but I shouldn't need that level of knowledge to perform such a basic task on a device that ships insecure by default.
Unfortunately, I doubt this law will have any affect on the raspberry pi foundation.
Linux would work for the vast majority of people if they'd only try it. It's only because MS shills such as yourself keep claiming otherwise that people don't try.
Linux these days is far easier to use than Windows, has better support, and runs almost everything that you can think of. Sure there are a small handful of niche applications that maybe 0.00001% of the population actually use that don't work, but that's hardly "most people"
There *IS* and alternative, people just have to quit being told it doesn't exist.
To add to this, if you want free support for MS products you get... none. If you want paid support for MS products, you pay through the nose, and the only solution is "have you rebooted? yes? ok, have you used the system restore cd?"
I have found linux support far better in that most times I can find actual answers on how to fix things, for free, and not the tired "reboot and system restore" that seems to be the bread and butter of "support" in the Windows world.
There have been several very practical alternatives for decades now. It's not that people can't migrate, it's that they simply don't. Is it ignorance? is it simple momentum? I'm not sure, but there is really no good reason for anyone to use Windows anymore in 2018.
I haven't owned a windows machine in 20 years, My wife (who is far from techie) hasn't owned one in 10. We haven't missed it in the slightest, and I haven't run in to anything that I couldn't do just as easily (or usually more easily) in Linux. And the more time goes on, the more stuff is cloud based anyway, which means that the vast majority of people could use ANYTHING that has a web browser in it to replace all of their day to day operations.
And don't give me the "but there's this one person that has an extreme niche case that doesn't operate on anything but windows!" argument, we all know that this is nowhere near the majority of users.
You already can. The mobile pages are obvious because they are completely crippled and missing any form of usability or information. If you end up on one and can't tell, is because the full site is also completely useless, and you might as well just stop visiting there.
Well I guess we better all switch to 14000 volts within the house, because only high voltages can possibly be efficient ever. For that matter why stop at 14,000 you obviously need a few million volts. Nothing else can possibly be made to travel any distance at all.
How about you get back to me once you have some experience with copper wiring ideally in a power transmission role. Because so far the stuff you're spouting is complete laughable nonsense
While it would be nice to be able to upgrade to fully autonomous, no Tesla currently produced is every going to be upgraded to fully autonomous, so that's somewhat of a red herring. Sure, I know they're selling it as such, but it's just another in an extremely long line of flat out lies from their marketing team. It is extremely include that they do not have the appropriate sensors to do full autonomy. No amount of software can fix their lack of sensors. These cars can't even properly so blind spot monitoring, and people think they'll be able to drive themselves?
There's nothing magical about 5v that makes it not travel great distances. It works great over long distances just as any other voltage does, you just have to engineer the wiring appropriately. One central power supply is way cheaper than several dozen, and the wiring will be way cheaper too. It also happens to be far more energy efficient. Builders go to great lengths to save pennies per job, this will save hundreds of dollars, they will do it. The only question is when.

Android use vanced. It's the official client, but with the ads stripped out and a few extra features. Find it on xda.
On Android I use vanced. No ads, otherwise it's the same as the official client. Find it on xda.
Ublock stops all ads on my laptop too. The only time I see ads is if I use the TV set top box, so there's a reason I never do that.

Not out of this air, out of company coffers, which in turn came from sales of TVs. Hence money from purchasers got given to lawyers.
Money does get created out of thin air all the time, but this isn't how it happens.
No money was created here, money was simply transferred from purchasers of TVs to lawyers.
This $17 million amount is more than Vizio made by licensing the data collected, according to a source with knowledge of the deal.
That's the important part. For these sorts of things to have any impact on corporations the punishment must be more than the profit from doing it.
