Comment Fracking to relieve tectonic pressure (Score 4, Interesting) 265 265

Why not take out of Oklahoma's or Texas's playbook and do some fracking near the fault line? It will likely cause earthquakes but hopefully they would be minor, and would relieve the pressure a little bit at a time, instead of all at once.

A two-car household is a common scenario, at least in the US (basically a two-adult household where most things are shared, like two married people for example), so the expense of having a second car is not an additional expense since both adults want/need a car anyway. In the two-car household, at least one of the cars is a commuter car. The other car may be a commuter car or may be a "family car" like a minivan/SUV. There's basically no reason why the commuter car can't be electric.

The other common situation that you're talking about is a one-car situation comprised of a single unmarried/unattached person not sharing cars with anyone else. In this case, I agree, there are a good number of reasons why you may not want your only car to be an electric.

There's nothing wrong with SOME diversion and trade of a natural resource. But there is something VERY wrong with doing it when you have a limited resource like fresh water that is being used badly.

Who determines what is a bad use and what is a good use? You? I claim that burning gasoline in your car is a bad use of the resources of the Middle East/Texas/Venezuela/Dakotas.

comparative advantage [snip]

You're right, it's not comparative advantage, it's absolute advantage, which is even stronger. The Great Lakes has an absolute advantage in water production, but the southwest has a huge absolute advantage in solar power production.

How about, instead of massive engineering projects, we just don't build cities where there aren't enough natural resources to sustain them?

So then, we should avoid building cities in the Great Lakes region, where it gets really cold in winter and people have to use natural gas that was mined in Texas and the Dakotas?

There's this thing called comparitive advantage. The southwest has tons of potential for producing solar energy, let's not shut down development there yet.

why do you have a "yard"?

I'm not the OP, but I'll tell you why I have a yard: I like the privacy and convenience it enables for me and my family for doing stuff outside. Public parks are great but cover different use cases. It's the same question and answer as why anyone lives in a single-family residence instead of a multi-family apartment/condo.

Encryption

Why Aren't We Using SSH For Everything? 203 203

An anonymous reader writes: A post at Medium asks why, in this age of surveillance and privacy-related bogeymen, we aren't making greater use of SSH for our secure computing needs?

"SSH is one of the most accessible secure protocols ever, second only to HTTPS of course. Let's see what we have so far: Binary protocol, mandatory encryption, key pinning, multiplexing, compression (yes, it does that too). Aren't these the key features for why we invented HTTP/2?

Admittedly, SSH is missing some pieces. It's lacking a notion of virtual hosts, or being able to serve different endpoints on different hostnames from a single IP address. On the other hand, SSH does have several cool features over HTTP/2 though, like built-in client authentication which removes the need for registration and remembering extra passwords."

Your part is only half of the free market equation, and if you do just that half, it will lead to lower GDP. The people commuting on those roads at that time aren't doing it for fun, they are doing it to get to or from jobs. If you reduce the trips, you reduce work accomplished. If you make the trips more expensive, you just took money that would be used to buy something else and gave it to the road authority.

If you still want to price freeway demand like that (which will restrict demand), you either have to be willing to give up the GDP, or you have to do something about the supply side. I don't see many people willing to give up GDP, so let's talk about supply. The usual free-market solution is for companies to see profit in the freeway-capacity market (due to the excessive demand and limited supply) and provide additional supply, thereby taking that profit. Roads are a natural monopoly mostly controlled by the government, but you can approximate what would happen on the supply side by requiring the toll authority to spend its profit on adding road capacity in particularly supply-constrained sections of road.

Submission + - AT&T Pauses Fiber Rollout, Citing Obama's Net Neutrality Regulations

AcidPenguin9873 writes: Following Monday's request by President Obama to the FCC to impose tough net-neutrality regulations on ISPs, AT&T has announced that they are pausing the fiber-optic network upgrades that they had previously announced for 100 U.S. cities. AT&T cited regulatory uncertainty as the primary cause for the pause: " 'We can't go out and invest that kind of money deploying fiber to 100 cities not knowing under what rules those investments will be governed,' [the company's chief executive Randall Stephenson] said."

all the companies that would have sold the jet fuel to Google at a profit did. The government acted in competition with private enterprise to fuel private enterprise aircraft.

You're ignoring the fact that extra jet fuel was simply available at a discount, because NASA had already bought it. What should NASA have done with that extra jet fuel? Sold it to a private jet-fuel company? Let's say that they did that. They would have had to sell it at a discount (maybe the same discount) because the jet fuel was located at an otherwise-unused airfield and would have to be transported elsewhere, which is not free.

Oh, you say, they could have sold it to the same private jet-fuel company that Google has contracted to fuel its planes! That way no one has to transport it - it's already in the perfect location! Knowing this, NASA should definitely ask for more money for the same jet fuel, because NASA has basically already paid the cost to transport and store the jet fuel exactly where the jet-fuel company needs it. Jet fuel company buys that fuel and sells it to Google at market rate (since Google would otherwise just buy different jet fuel from one of jet-fuel company's competitors.) I don't see how the private jet-fuel company would make any more money than normal. They saved on transport/storage cost but had to pay that savings for the fuel (because NASA knew they were saving). That is, unless you expect NASA to give the jet-fuel company the same sweetheart deal on the jet fuel that it gave Google. And if NASA did that, then it would be giving a private company a taxpayer-subsidized advantage, the very thing you were just complaining about.

NASA was not continuing to buy jet fuel at its government-discounted rate for the sole purpose of fueling Google's planes - the fuel already existed, and the question was what to do with it. NASA either gives someone a deal on it and someone gets a taxpayer subsidy, or doesn't give anyone a deal and all private-company costs and profits are identical to what they would be if NASA's fuel wasn't there at all. NASA comes out ahead in the latter scenario, but that's not what you complained about.

Money is the root of all evil, and man needs roots.
