It's not just the cabin that needs to be heated. The battery heating system consumes a fair bit of power on very cold days. You'd think they would heat up enough from just being used to power the car, but apparently heating is still necessary and affects range quite a bit.

Yep, and they also promote things that hurt the environment. Here in belgium they were actually encouraging people to burn woord for heating, since wood was renewable. Then they suddenly realised how much fine dust and smog was being created by those wood stoves. Oops.

And don't get me started on nuclear power. New designs are perfectly safe and produce almost no waste, yet we can't build them because nuclear power is supposedly dangerous and creates waste that will poison the planet forever. So, for lack of alternatives, we keep extending the life of older plants until they blow up. And we try to replace them with renewables that actually pollute more. Those solar panels don't grow on trees. More people have been killed in the construction of wind turbines than in nuclear accidents. Oh, well, looks like I've gotten myself started. I'll stop now.

As for your PS4 games on Xbox, I dunno, AFAIK you are allowed, or at least not disallowed. I don't know how that'd work exactly. Maybe you want to play them on your microwave oven too. If you can convert the object file formats and the machine instruction sets and solve the different rendering engines, and all the other physical incompatibilities then I'd be willing to bet you could play them.

And then get sued for violating the DMCA.

If you're running a server for a big company (say, Google or FaceBook) and every image is only half as big, that means a huge reduction in the number of servers you need, power consumption, etc. Less congestion on the internet, more responsive servers, less wasted energy, etc...

I imagine you also have a car that guzzles up twice as much gas as other cars, but who cares since you can afford it?

PNG is used extensively in Apple products. It's the standard format for non-compressed images in iOS apps, along with jpg for compressed images. Apple recommends using png for user interface elements, and jpg for pictures. Which makes sense, since jpg can compress a picture to 20% of the size with very few artifacts. Size does matter for mobile apps. And I wish people would realize that it matters for servers, too. Yes, available bandwidth is enormous these days. But if your server is serving pages that are twice the size and your audience is large, you're going to need a bigger server room and use considerably more energy. Servers are on their way to becoming the biggest power hogs on the planet. Smaller images mean less hard disks and less data pipes.

And some of the smaller websites will just mail your password to you on request. Just had one like that last week. Unbelievable in this day and age.

And another website I logged into last week, a frequent flyer program for a major airline, had a maximum of 6 numbers for the password. Not characters, numbers only! No idea how they store it, but something tells me they're probably not using MD5 and have never heard of salt.

The absent ones are always at fault.
