Er, just trolling for mod points, and I guess I know my audience for the most part... I was really just looking for a nice place to link to that funny image, and your post sounded smart (though TBH I didn't really understand what position you were arguing for or against, but I agree with the statements you made).

But just to explain my AGW analogy... should we be worried about asteroids enough to spend money on asteroid interceptors, even though any kind of payoff is likely only once every 70,000 years or so? Should we be worried about climate change enough to spend money on trying to cram more people onto Earth, or just let the natural cycles of mass extinctions and famine run its course?

The fine article is somewhat silly, because first they complain about how bad at statistics people are, but then go through the math that the odds of anyone dying due to asteroids are 1 - in 70 million per year.

assuming our world’s population remains level at 7 billion indefinitely into the future

which is
1. a bit ridiculous that the population will hold steady at 7 billion the forseeable future, not that it matters because humans have difficulty relating to any population above a couple hundred.
2. over enough millennia, even with those odds, we'll see definitely see something. Probably not in our lifetimes, but likely on a civilization scale of 10,000 years.
3. Yes, TFA mentions that most of the solar system debris has already been absorbed by Jupiter and the like, but seems to ignore some other million-year scale cycles for encountering space debris http://www.dailygalaxy.com/my_...

Are people fear-mongering? Definitely. Is any effort we make to tackle the miniscule risk of asteroid impacts or climate change wasted? No. Are historians in the distant future going to look back on our culture and and say "silly fools, they wasted so much time and effort worrying about X that they didn't notice the real issues piling up to destroy their civilization" no matter what we do? Hell yes.

Submission + - Coral islands defy sea level rise

schwit1 writes: Despite having some of the highest rates of sea level rise in the past century, the 29 islands of Funafuti Atoll in the Pacific show no signs of sinking.

Despite the magnitude of this rise, no islands have been lost, the majority have enlarged, and there has been a 7.3% increase in net island area over the past century (A.D. 1897-2013). There is no evidence of heightened erosion over the past half-century as sea-level rise accelerated. Reef islands in Funafuti continually adjust their size, shape, and position in response to variations in boundary conditions, including storms, sediment supply, as well as sea level.

Be aware as well that the cause of the rise in sea level here is not clearly understood. It could be the global warming we have seen since the end of the Little Ice Age of the 1600s, or other more complex factors.

No vertical tabs 10 years after widescreen displays started spreading widely?

Yeah, Tree Style Tabs is the killer feature that's keeping me with Firefox. There are a couple of Chrome extensions that kinda-sorta-not-quite do the same thing, but nothing that just moves the damn tabs to the side so I can have a dozen open and still read them. I'm probably stuck with FF until Chrome has a suitable substitute or FF breaks it entirely.

Yeah, large, mass-extinction asteroids are only a problem every 70 million years.

By that logic, why even bother worrying about AGW, since even by the worst predictions it won't have any horrible effects for the next 100 years or so. So just sit back, relax, and enjoy life! .... there's nothing that could possibly happen that Earth wouldn't completely recover from in a couple million years.

Politics are not Pro- or Anti-Science. It is weather the science is political useful for them or not. Otherwise they will be happy putting their head in the sand.

This. If you know anything about lawyers and law, the first tenet is NEVER ADMIT FAULT. No good can come of it. People might then expect you to pay for damages or whatever.

Environmentalists make the mistake thinking that conservatives are stupid. That is not the case. The only thing they care about is that they will not have to pay for or be part of the solution. Any time you spend trying to convince them otherwise is wasted.

The other bit is that politics is never proactive, always reactionary. No environmental protection or anti-pollution law was ever passed until something was already FUBAR, be it due to the London yellow fog, or smog over LA, holes in the ozone layer, or Chinese urban centers shutting down due to respiratory issues. The politicians will maybe finally get around to doing something substantial about AGW after there's a refugee crises from low-lying areas, like the Netherlands, Bangladesh, Louisiana, Florida, etc. Chances are, they still won't blame AGW, since it'll be sea swell from a hurricane/typhoon that does those population centers in, but at some point they'll get tired of throwing money at those places to rebuild. Fortunately there are already a lot of migrant refugee boats in the Mediterranean and Andaman Sea for other reasons, so we're already slowly building a framework for dealing with these kinds of things.

Comment Re:When will their price be on par with ICE cars? (Score 1) 107

Even in California where we're paying $0.15 - $0.20 per kWh of electricity, electric vehicles save so much gas that they almost pay for themselves.

Only because you're getting ass-raped on gasoline as well. When I topped off the gas tank here in Vegas before driving down to LA last weekend to visit my nieces, I paid $3.04. I pulled over in Baker for a snack. The gas station next to the jerky place wanted somewhere around $4.50! Granted, Baker's never been the cheapest, but gas in Barstow was still around $3.70. I think it was $4.something around LA, and by the time I was running on fumes Sunday morning (driving down to San Diego to make everything worse), I ended up paying right at $4 per gallon ($3.999, if you want to be pedantic) for a full tank in Carlsbad.

Gasoline is sent to Las Vegas from California by pipeline, so how is it we're paying considerably less for the same fuel after it's been pumped through ~300 miles of pipe?

Comment Re:Android. The "PC" of mobile devices (Score 1) 92

You are generally safe with Nexus devices, since you have the best chance of upgrading to the latest OS.

A device with an unlocked bootloader is also more likely to be more future-proof. I have a newer version of KitKat running on my Galaxy Tab 2 7.0 (4.4.4) than on my considerably newer Moto X (4.4). The tablet's running Cyanogenmod...have no idea if Samsung ever got around to spinning a KitKat build for it, and don't particularly care at this point as the only thing that doesn't work under Cyanogenmod is the IR blaster. My phone, OTOH? Motorola has pushed newer versions (maybe even Lollipop now), but the bootloader is locked and you can't even root newer firmware versions (rooting 4.4.4 requires an unlocked bootloader first).

That new phone that Asus introduced earlier this week sounds interesting, and there's already an unlock for it. The only downside is the ginormous, almost tablet-sized screen. The Moto X is barely larger than the iPhone 4 it replaced, but it seems hardly anybody wants to build a full-powered phone that'll still fit in your pocket anymore.

But it does require extra fuel. I'd have expected that fuel to be more than the weight of a parachute system, though perhaps not: it would be lowering a mostly-empty tin can.

I imagine that it's a bonus to be able to have that kind of precision on your rocket engines: if you can get them down, then it may provide advantages in going up. Certainly it's nice that you've proven that kind of control.

Comment In particular, NO redundancy. Reliability drops. (Score 5, Informative) 226

Losing data goes with the territory if you're going to use RAID 0.

In particular, RAID 0 combines disks with no redundancy. It's JUST about capacity and speed, striping the data across several drives on several controllers, so it comes at you faster when you read it and gets shoved out faster when you write it. RAID 0 doesn't even have a parity disk to allow you to recover from failure of one drive or loss of one sector.

That means the failure rate is WORSE than that of an individual disk. If any of the combined disks fails, the total array fails.

(Of course it's still worse if a software bug injects additional failures. B-b But don't assume, because "there's a RAID 0 corruption bug", that there is ANY problem with the similarly-named, but utterly distinct, higher-level RAID configurations which are directed toward reliability, rather than ONLY raw speed and capacity.)
