Comment Re:But will it mark gmail and google.com as spywar (Score 2) 24

Why would Google have any control or visibility of anyone's connections, unless either that person also independently uses Google services in some sort of ISP capacity or the sites they are visiting independently use Google services in some sort of hosting capacity?

Since then, Google has seen a 23 percent reduction in the fraction of navigations to HTTP pages with password or credit card forms on Chrome for desktop.

Just ask yourself how Google can possibly know that and you can get a pretty good idea of where it really stands on the spyware/privacy issue.

I'm not sure we should be dictating commercial restrictions on the supply of all creative content to an entire continent based on the three people in that continent who are studying film or music analysis.

In any case, lots of people are commenting here as if forcing sales to the entire EU to be at the same price will bring the cheaper prices to the richer nations. It seems far more likely that it will bring the more expensive prices to the poorer nations. Your "background music" licence is exactly the kind of expendable luxury that could suffer under the more uniform regime.

Sorry, but that just isn't how economics works.

Firstly, market segmentation is absolutely routine, including by purchaser power. There are countless ways to appeal to people who can afford to spend more, and businesses do this all the time. Have you ever seen a box for a "coupon code" when you ordered something online? That's market segmentation in action. Post coupons to everyone on the poorer street in your example, and now everyone isn't paying the same price.

Secondly, as someone who actually runs some online facilities at-cost, I can tell you that it is a real problem for people in less well-off nations if your price online is the same everywhere. You can't lower the headline price because if everyone was paying the lower price then you literally couldn't afford to keep these services running at that point. However, then the people where salaries and costs of living are generally lower can't keep up, so they lose out. The kind of adjustment we're talking about here is the online equivalent of posting coupons to all the homes in the poor part of town.

The genuine, uniform market price you're talking about doesn't exist in most real markets, because most real markets are not uniform.

That accident sure was a black eye for them... but the design is now better because of it. Also, gotta love having an aircraft whose crashes are in slow motion ;) "Coming soon on World's Least Dramatic Air Crashes!"

I imagine for the pilot it was sort of like when you're driving down a slope on ice and you lose traction, and you end up skidding down the whole slope at a several kilometers per hour: First, alarm and futile attempts to regain control, followed by acceptance, then "Okay, you can stop any time now...."

You're talking about a monopoly situation. For works covered by copyright, that already exists in the sense that for any given work the rightsholders can decide to offer it only via certain channels.

However, unless those works are also essential, the customer still has the option not to buy them at all, and if the price is too high they will choose to spend their money elsewhere.

Moreover, while individual works may have a monopoly supplier, most creative works will be in competition with other works for providing information, entertainment, etc. Those competitive effects also moderate pricing, preventing the kind of "extraction" model you're talking about.

Around here, Amazon won the pricing war for most CD/DVD/Blu-ray content long ago, yet today it would still be cheaper for me to binge-watch a lot of TV shows through Netflix than through buying all the box sets. Amazon's prices for buying permanent copies of films or shows I really like on disc aren't much different to what they were a few years ago when you could still easily buy the same things in bricks and mortar stores.

Airships are not party balloons; they don't "pop" when you make a hole in them. They have low overpressure and a huge volume to surface area, so a "bullethole" is just a slow leak; it's not even a reason to land. A helicopter is far more vulnerable to small arms fire than a helium airship.

As for what it buys over a helicopter, show me a helicopter that can move 50-500 tonnes payload at a per-kilogram rate cheaper than a freight truck while flying halfway around the world without refueling. Because that's what people are looking to build with this new generation of airships. Even Airlander 10, which is just a commercial prototype for the Airlander 50, carries more payload than the largest helicopter used by the US military, the Sikorsky CH-53E Super Stallion.

A common usecase for large airships is remote mining operations. They need big, heavy pieces of equipment brought into places without roads. Currently, the first step is to build a road - which is expensive and environmentally destructive. An airship needs only a clearing - and the "skycrane" variants don't even need that.

Another advantage is that it's much easier to design them to carry "bulky" cargoes than airplanes. Again, especially "skycrane" designs where the cargo hangs beneath.

Given the fact that it's rigid, and given the size of Hangar Two and the fact that the frame is said to take up much of the hangar, it's probably much larger than Airlander 10.

Probably also doesn't look like a giant rear end ;) Even if it's a lifting body, the fact that it's a rigid airship (from the description) means that they can shape it however they want. So probably something like a flattened teardrop, if they go for the hybrid (lifting body) approach. Which generally seems pretty popular these days, for good reason (lots of extra lift at little cost, higher top speeds because you don't have to have as large of a cross section for a given cargo, etc). But of course there's nothing here to suggest whether it's actually a hybrid.

I'm wondering what the "innovation" is. Because I'm sure that he's not doing this without some angle, something unusual that he's doing with this one vs. other airships. Some sort of wow factor.

Sergei, blow me away with something totally crazy. Like make its skin transparent, fill it with heliox and have people live inside the envelope farming, like an Earth prototype of a Venus colony ;)

But honestly, my expectations are that it's a generic freight carrier, and that the twist would be that it's a rigid lifting body. Maybe if we're really lucky, solar-powered too.

I personally find it very exciting. I knew that Alphabet had rented the Moffett Field hangars from NASA and were rennovating them. But their official stated purpose for doing so was to store a number of company planes. This is the exciting part:

Engineers have constructed a metal skeleton of the craft, and it fills up much of the enormous hangar.

So first off:

1) It's a rigid airship. Which used to be common but is now rare. Zeppelin NT is a semirigid, with a trilobate truss inside, but there's not many other examples. Rigids are favored when you're building something very large, as they reduce the stress on the skin.

2) It's huge. Hangar 2 is 52,1 meters high, 90,5 and 327,7m long.

I hope it's a lifting body! If I'm not mistaken it'd be the world's first rigid lifting body airship (correct me if I'm wrong!). Either way it's yet another sign that we're - at least temporarily - entering a new lighter-than-air renaissance. Who knows whether it will last, but it's great to see so many companies giving it another shot, making use of modern technology and design. Because there have been some huge improvements since the old Akron / Macon days. Also wonder about the fuel. Something like Blau gas, so it's buoyancy-neutral as it burns?

Of course, not everything in the article is exciting or new...

He went on to describe a prototype he was considering of a helium-based craft that appeared to breathe. "And so the way that works is that the helium in the main envelope is taken and stored in bags inside the airship at a slightly higher pressure," he said. "As you do that, air is taken in from the outside into essentially like lungs that are attached in the side of the vehicle. So the analogy of breathing is a good one. And the overall lift of the vehicle is equal to the weight of the air that is being displaced by the helium. And as you change that, you can control the amount of buoyancy that the vehicle has."

Um... yes, that's how lift cells work.... you either use them or you use ballonets, your choice... there's a couple other possibilities, like high overpressure superpressure balloons, or compressors + gas tanks, but the former doesn't scale, and the latter generally comes with too much mass and cost penalties with too poor responsiveness.

BTW, for those not familiar with the Macon and the Akron, I definitely recommend reading about them. They were literal flying aircraft carriers. You know how a landing jet on an aircraft carrier catches a cable with a hook? They did that too, but in the other direction - they caught a "trapeze" on their topside. They were then raised into the hangar, which was designed for five airplanes.

They unfortunately weren't long in service. Both of their losses could have been prevented with any combination of better weather prediction, computer controls, and better lift control. The Macon's loss was also stupid in that they were flying with unrepaired structural damage, out doing fleet maneuvers.

It seems unlikely that EU law will prevent a vendor from selling something at all in selective member states if there is a good reason not to. We looked into this issue when the EU VAT mess was the big news a couple of years ago, fearful that some sort of anti-discrimination provisions would say otherwise. The experts made some straightforward arguments that, for example, declining to sell to customers elsewhere in the EU would be OK if the costs of operating the new tax scheme were prohibitive, because that would be a strictly commercial decision. Presumably complying with the law of the land would also be considered an acceptable basis for making such a decision.

The EU is working being a common market, where it started.

That's lovely, and when the economic situation in all EU member states is similar, maybe they'll achieve it. In the meantime, it is far from clear that this is a good thing.

At least in the sort of context we're talking about here, the "real market price" you mentioned is what someone is prepared to pay for something, no more and no less. Forcing people from areas with very different economic situations to pay the same price just means a lot of things won't be accessible to people from those places that can't afford the same rates as their wealthier neighbours.
