That depends where you're living. Here in Quebec, 90% of homes are heated using electricity, because it's cheap thanks to our huge hydro resources. In the winter, it's usually too cold for heat pumps to work. To give you an idea, here in Montreal, average temp for last february were -19C (-2F). A heat pump can save a bit during fall or spring, but usually the savings aren't worth the purchase & maintenance cost of the pump. It's all resistive heating.

Clearly "what the people want" isn't working here. So why don't they simply sell the cars direct there anyway and disregard the law? Although I could not find a poll for Virginia, a Texas poll showed 85% of people in favor of allowing direct-to-consumer sales of cars. It would seem near-impossible to get a unanimous verdict to convict, as is required in Virginia.

And this is why we should not teach CS101 in Java or Python. If they'd been forced to use C this whole experiment would have turned out differently.

Not at all. If you wrote your C in memory string handling as stupidly as they wrote the Python and Java you will still get worse performance in C (e.g. each iteration malloc a new string and then strcpy and strcat into it, and free the old string; compared to buffered file writes you'll lose). It's about failing to understand how to write efficient code, not about which language you chose.

That's not quite true. The SPA line is the Cisco small business line, typically used with small Call Manager Express or UC500 series boxes.

At the same time though, if a device on your LAN is compromised enough that it can be used to upload XML files to another host, you have a lot more to worry about than a vulnerable phone. In fact the attacker could also install a SIP gateway on the compromised host with a phone's MAC address and it would work, so having the physical phone itself be vulnerable is not much of an extra threat. Whence the low severity.

Because Range Voting is more expressive than Condorcet methods. Suppose I am very satisfied with either of two Libertarian candidates, but would say "hell, no!" to Hillary Clinton. Merely voting "Paul > Johnson > Clinton" does not adequately express that. In fact with a Condorcet method, a more rational vote would be "Paul > Johnson > Hitler > Clinton" (knowing that nobody else will vote for Hitler.)

Also, Range Votes are usually normalized so that each voter has equal influence.

Let's say that domestic spying is your #1 concern - who do you vote for?

If I were unilaterally pick who becomes the next president I'd pick Ron Paul, because I believe he would put a quick end to domestic spying (and because I'm a pretty hardcore libertarian.) However, the rational thing to do is to select from whichever of the (D,R) candidates I believe is infinitesimally least bad, because it is certain that one of them will win.

If we used Range Voting instead of plurality voting then the rational decision would be to cast an honest vote. In my case in the last election it would be something like Hillary=0%, Obama=10%, Romney=15%, GaryJohnson=85%, RonPaul=100%. Range voting not only allows you to express all of your desires, but does away with the need for political parties/primaries.

But in our current system - vote for who?

RAM is very important if you use high resolutions. If you game in 1080p, then yeah this won't tell you much. If you have a 4k monitor though, 3GB isn't enough so you can at least look at the RAM to narrow your selection, then look at benchmarks.

I'll just paste another reply I made above about natural monopolies.

Natural monopolies are called natural because that's the way the world works. They exist no matter what the government does about it.

Let me give you an example with roads. Let's say all roads are private; people charge a toll to pay for each road section. You have a road from A to B. The entity owning that road has a natural monopoly, even without any regulation. This is because let's say competition adds a second road from A to B. Now, people use either road and traffic on each road drops by half. Suddenly, neither roads can pay for their maintenance because traffic is too low. Competition doesn't work well with infrastructure because reality gets in the way.

For last mile cabling, you have the exact same issue. If you allow 30 companies to have their own infrastructure and run cables to people's home, only 5% of that infrastructure would be in use at the same time, but all the rest still requires maintenance and investment. The end result would make it impossible for any of those 30 companies to turn up a profit.

With hindsight, we should have gone about cabling differently. The city should have owned that last mile cabling to each home, with them terminating in various city NOCs. Then you give access to all the service companies to these NOCs. Voilà, you now have perfect competition. You would only need neutrality laws only for the cities themselves in that scenario so that no preferential treatment is given to any company. It's a bit too late to do it properly now though.
