The first point has been addressed many times already - even if you're powering your electric car on 100% fossil-fuel electricity you're still doing better than burning gasoline.

A centralised generating station is much more efficient than lots of gas engines that are about 30% efficient. Obviously it would be ideal to move to renewable generation, but that will also be happening as those sources get cheaper and more effective. You also have to factor in transmission losses and charging losses, but even with these included you're still ahead.

Ideally your work truck would be hydrogen fuelled.

Your typical week sounds like the ideal workload for an H2 vehicle.

Keep all of the truck the same as a pure electric design (motors, chassis, etc), but swap the battery packs for a hydrogen tank and a fuel cell.

I think that will be the best way to reduce emissions in the future - pure electric for the bulk of commuters and so on, with H2 for large commercial vehicles. The bulk of the manufacturing can be shared across the lines (for example, they'd use the same electric motors) but each system has pros and cons.

Obviously a big con of H2 systems is infrastructure for H2 production and storage. If we can crack the catalysis issue (making it cheaper to manufacture quickly from bulk electrolysis than it is currently, and moving away from steam reforming of natural gas) then it can be made anywhere you have a good source of electricity and water. Given that you need a solid electricity supply to provide recharging stations for EVs, this part will be solved. Just need to crack the other part now.

You don't need Apple's drivers for bootcamp for the GPU - you can just install the AMD or Nvidia ones that AMD and Nvidia supply for windows.

The one Apple ships with the bootcamp driver package (that you install from a USB stick when you first set up windows and has everything you need for the keyboard, networking, bluetooth, etc) includes one of those OEM drivers from AMD or Nvidia, it just tends to be an older one since they don't update the package all that often.

Once you have windows installed though it's no different to any other windows machine in terms of GPU drivers.

You seem to have missed the sarcasm inherent in my original comment.

The GP was claiming that they could just hose the wings down rather than using an anti-bug coating.

I was just wondering out loud how that would work when the plane is in flight given that the hose probably has a finite length.

It was pretty clear what he meant, you were just being a dick.

If you're following the comments, why didn't you log in?

It was clear that the original poster didn't understand how the technology worked.

Also, if my comment to him is considered "being a dick" then my goodness he must have a thin skin. He'd better be careful on the internet. What specifically about it is me "being a dick"?

You don't get it.
What vux984 is saying is that he set up the magic trackpad so that he only has to touch the trackpad to click, and he does not have to exert a force on it.

I personally got rid of everything that requires to exert an additional vertical force on the trackpad the day I tried to use it on my laps. I'm talking about a wireless magic trackpad of course. I replaced everything with two and three fingers gestures, and it feels so confortable that I setup my laptop the same way, and never looked back. So force touch for me doesn't make sense, but I have to admit that I have not tried a force touch enabled magic trackpad.

I do get it. He is saying that he has never used the force touch feature when that's literally impossible, even if he taps it lightly enough to just register his finger - the cap sensor and the strain gauges work together on the new trackpad. Je just didn't understand that.

No, it really doesn't.

It really doesn't MATTER.

There are two thresholds where it clicks - the fact that its haptic vs mechanical is irreelevent. I never ever touch it with enough force to engage either click threshold.

So any additional functionality mapped to touching with greater force; I'm not ever using. So it may as well not be there.

Ah, so you're changing your argument. Fair enough.

I was just pointing out that you were factually incorrect and based an argument on it. Next time you say that you don't use any part of a technology that you literally have to (because that's how the trackpad works in its entirety) you'll know a little more about it.

You have finally realized that your touchscreen controller actually provides a pressure strength and are able to hype it up like it's revolutionary.

Not even if we realize the limitations of pressure sensing of a standard capacitive controller and add additional sensors to make the detection less granular is this something new. I don't know how long Synaptics (touchpad manufacturer) have had their capacitive+force sensor combination available but it is at least two years, but even ignoring that the idea and implementation isn't anything new.


Err, no.

Apple's implementation of force touch on the Macbook Pro trackpad (where it is current used, not counting this rumour that it will be on the iPhone) uses a set of strain gauges to measure the applied pressure. It doesn't use the touchscreen controller.

You might want to actually look up how it works before trying to score a "sick burn" (is that what the kids call it these days?) from your armchair quarterback position.

I also don't see where Apple are hyping it up to make it seem like a revolution. They are advertising that the MBPr and MB have it, but I fail to see how their advertising materials claim it's revolutionary. Unless you think the term "whole new way to experience a trackpad" means that, and not "this trackpad works differently than the old ones due to the numerous new ways you can use it due to the force sensors"

Apple is frequently guilty of hyperbole when it comes to advertising, but on the force touch it's pretty understated. Did you just assume they would claim it was a revolution that had never been seen before? Given that you don't understand how Apple's implementation works I have to assume you've done zero research on it. Google (a popular search engine) can tell you quite a lot about it if you're interested.

In practice, failures in system development, like unemployment in Russia, happens a lot despite official propaganda to the contrary. -- Paul Licker
