I was going to add (and did add) the suggestion that you read the paper so you could post informed opinions rather than uninformed ones. (It amazes me how often my signature quote turns out to be exactly relevant.) And that led you to do it, so I totally count it as a positive contribution to the discussion!

I do, however, think you're being overly harsh toward this paper. They crossvalidated their results, and also included negative controls in the study. If their statistics were really as badly done as you claim, they would have found just as strong predictors based on the pleasant and neutral images. But they didn't.

I'm not at all surprised that, as a liberal, you would interpret it that way. Even though there's nothing in the study that actually supports that interpretation. A conservative, of course, would almost certainly not interpret it that way. The liberal and the conservative are both being equally emotional and non-rational in their reasoning.

Think carefully about what you just did. You first decided (based primarily on emotion) what conclusion you wanted to reach, then interpreted the data as supporting that conclusion. You did that (as everyone does, many times a day) despite the fact that it required wild extrapolations, and there are tons of other interpretations equally consistent with the data. This is exactly the sort of thing this article is talking about. Humans are not rational. We make decisions based on emotion, then rationalize them to convince ourselves they were actually based on logic. If you are human, then you are not rational. If you believe you are, that's just an example of one of your irrational beliefs.

So maybe you should read the paper? Then you'll know. Instead you just posted lots of totally uninformed speculation about what they "probably did" while presenting this as some sort of authoritative view. In just a few minutes you could have skimmed the paper (it's not very long and quite clearly written), then posted a useful commentary that would actually add to the conversation.

Example: a few releases ago they made scrollbars thinner (making them harder to click), and also made them disappear by default. All this to "free up the space" that was being "wasted" by scrollbars. Now in Yosemite they're getting rid of window title bars in many apps, making it harder to move windows around. This is for the same reason: to free up space being used by title bars.

My computer has a 24" screen. The space taken up by scrollbars and window titles is completely insignificant. The inconvenience caused by not having them is very significant. This is a design decision that might have been justifiable 15 years ago when a 17" monitor was considered large, but today is completely absurd.

From the article: "In a statement, the company, the Pentagon's largest supplier, said it would build and test a compact fusion reactor in less than a year, and build a prototype in five years." So if they haven't even built a reactor yet, much less tested it to see if it really works, what exactly is the amazing breakthrough they're claiming?

Alaska is much colder, but it's one of the states with lowest energy use. So is Maine. Conversely the second worst state by energy use is Kentucky, which has very mild winters. The list of states with the highest energy use includes both North Dakota (bitterly cold) and Louisiana (nearly tropical). But the one state that is truly tropical--Hawaii--has the second lowest energy use.

Energy use has far more to do with public policy than weather.

This is a standard fallacy, that there's a direct correspondence between energy use and standard of living. Take a look at the actual numbers for what a "circa-2010 American standard of living" actually means for energy:

http://energyalmanac.ca.gov/el...

The average person in Wyoming used more than four times as much energy as the average person in California. Do you think that means their standard of living was four times as high? And no, it's not just that Wyoming is a large rural state. California has huge rural areas too. And Washington DC consists entirely of one city, but its per-capita energy use was nearly three times higher than California's.

What this actually means is that California has taken energy conservation seriously for decades, and has had government policies designed to promote energy efficiency. And those policies have worked, really really well. An "American standard of living" does not require ridiculously high energy use.

Exactly. Building any kind of colony in space will probably be easier and less expensive than building it on Mars. If nothing else, it will be a lot easier to send the initial manufacturing equipment there, since it will be a lot closer to Earth. And once it's built it will have lots of advantages: closer to Earth, no gravity well making it hard to come and go, closer to the sun (hence much greater supply of solar energy), and you get to live in normal Earth gravity (from rotating the colony to create artificial gravity) rather than the 38% Earth gravity you get on Mars. We don't even know if humans *can* be healthy living long term in such low gravity.

Way back in 1975, NASA estimated the total cost of building a space colony large enough to permanently house 10,000 people at $190 billion. And that was relying entirely on 1975 technology. This is totally something we could do, if we really wanted to.

Agreed. The key is to find good readers, and then listen to their solo projects. The best readers are just as good as most professional recordings.

There's enough deuterium to last 100,000 years, but we'll go through it all in 1000 years anyway. Never underestimate the ability of humans to be wasteful when they don't have an incentive to be efficient.

Fortunately, solar doesn't have that problem. It gets delivered to us at a nice steady rate, and that isn't going to change much for many millions of years.

That's not what I mean. That was the time between when someone came up with a cute toy and when someone starting trying to do something useful with it. I'm talking about how long we've had an active fusion energy program spending large amounts of money every year to try to create something practical. When they started out, they thought they could have something in ten years. Ten years after that, they thought they could have something working in ten years. Ten years after that, they STILL thought it was about ten years away. Sixty some years and billions of dollars later, even the optimists are saying it's 20 years away.

Besides, you demonstrated my point exactly. Centuries before anyone tried to develop a steam engine into a useful device, they already had a working proof of concept.

Why do you think that? What's so amazing about fusion that makes it so much better than every other technological achievement in history? Sure, it would solve all our energy problems for about a thousand years, at which point we would have burned through most of the available fuel because, having no incentive for efficiency, we would have wasted most of it. (Yes, I'm cynical about humanity.) But solar energy is equally capable of solving all our energy problems. And unlike fusion, it's a real technology that actually works today.

No, I don't think it is. Pretty much every technology that has gone on to be successful has started from a simple, working proof of concept and then scaled up from there. That covers everything from the steam engine to the telephone to nuclear energy to the microprocessor. Contrast that with fusion energy: 60-odd years of work, many billions of dollars spent, and we still don't have a minimal working proof of concept.* That's pretty depressing. Can you name any other technology that started out as badly yet went on to become successful? I can't think of one.

Given the history, I think extreme skepticism is the only rational response.

* By a "minimal working proof of concept", I mean a controlled fusion reactor (not a bomb) that produces more energy than it takes to run the reactor (and hence actually functions as a power source).

Don't be put off by the clueless submitter. This is actually a really cool project that goes way beyond existing types of automation. This quote, for example, gives a sense of the kinds of things they're trying to enable:

Here's one they don't include: totallyweirdsounds.com (all Tuvan throat singing, all the time!) Never heard of it? Of course not, I just made it up. But suppose I wanted to start that site. Millions of T-Mobile users would say, "If I use your service, it'll eat through my data cap, but if I get my Tuvan throat singing from Spotify it doesn't." I'd be at a huge disadvantage.

Net neutrality is about providing a level playing field. Not just for established companies, but for everyone. Maybe T-Mobile is doing this with good intentions, but they're creating a barrier to any new music streaming service that comes along. Besides, if they want to raise their customers' data caps (which is effectively what they're doing), why not let customers use that data however they want?

And it's not like they even have all the major services. Google Play Music? Nope. TuneIn? Nope. SoundCloud? Nope. Those, perhaps by coincidence, are precisely the services I stream music from most often.

Congratulations, you're being a troll. They managed to take their existing app written for a completely different platform, and port it to the web in a way that runs flawlessly on my four year old laptop. Without having to rewrite the whole thing by hand in Javascript. I'd call that a big win, and a really cool achievement.
