My variant is that all, or almost all the civilizations the aliens know about formed around red dwarf stars. It's nice and stable there for very long periods of time. We're only stable here by luck - and our big moon helps some.
Another fun thing to think about: If you look at our system as a whole, from a very long distance, we look like we're still a pre-multicellular world. Sure, there's free oxygen and water (Earth), but there's lots of iron still to be oxidized (Mars), and lots of free CO2 (Mars and Venus). I imagine there are a lot of pre-multicellular worlds (like Mars IMHO) orbiting yellow stars, so we don't stand out. (But for our radio transmissions.)
Why does the transition to IPV6 have to happen immediately after all IPV4 addresses are allocated? Why can't someone set up a market for IPV4 addresses that can then be bought and sold? At that point, the transition to IPV6 wouldn't happen very quickly, until the cost for IPV4 addresses exceeded the cost for IPV6 equipment. Then it would happen very quickly.
Actually it could be both. TFA doesn't say "warrant canary"; it says "duress canary". Duress could be anything from NSA to Russian Mob to simply getting sick of working on the project.
Furthermore, if the "duress canary" was set up right, inaction would cause it to appear. So it would be the default result of a "rage quit". And maybe they were too sick of the project to bother with anything better.
Besides Git we have Mercurial and Bazaar. All born around the same time so solve the same problem.
I don't know about Mercurial, but have you ever used Bazaar? While Git is written in C, Bazaar is apparently written in Python, and it's even slower than that implies.
This idea would only work if either the planet's moon was right in front of it from out point of view, just going behind it or just coming out from behind.
Well...yes, and no. I'll start with the no: The idea is that if the planet and moon are both in front of the star at the same time, no matter how they're aligned, the spectrum will look like it's being filtered through their combined atmospheres. They're just so far away that everything blurs together.
But it does seem like there should be ways to tease them apart. If the planet and moon are widely separated, there should be a brief period when only one atmosphere is filtered at the beginning of the transit and again at the end. This may be too brief for current technology to detect. It could also be mistaken if the planet is really a single planet that is somehow highly asymmetrical. (Perhaps something evaporates by day and condenses by night?)
The other thing that comes to mind is that a moon orbiting a planet will likely have to move fast. Astronomers are good at calculating speeds, especially relative speeds, with redshifts. They've measured the very slow motion of stars as large planets orbit them. So if they detect that the signatures of the two gases have significantly different redshifts, they can conclude that one gas is on a planet while another is on a moon. This doesn't eliminate all false positives - the planet and moon could be close together, and thus not moving much toward or away from Earth, when the transit happens. But multiple transits are likely to have different alignments, unless either the moon's orbital period is synchronized to the planet's, or the planet and moon orbit in a plane perpendicular to our line of sight. Both of these are not impossible, but are unlikely. An asymmetrical planet with a high rotational velocity could also produce a false negative, but this is also unlikely.
SSDs aren't actually very good for caching. (Though they sell drives and software specifically to do that.) They're better at WORM (Write Once Read Many) or Write Rarely Read Many (WRRM?) tasks. Like installing an OS and other programs there and not modifying them often. (Where "often" = "every few minutes".)
That said, I do have my computer's swapfile on my SSD. But only because I only have 4GB RAM and can't upgrade.
I disagree on 'maxing' it out.... 8 GB will be fine for the next 4-6 years at least.
And 640k ought to be enough for anyone.
"Enough" RAM is not noticeable. "Not enough" is very noticeable. What "enough" is is likely to continue to increase. More than enough RAM can also improve disk caching, though this has diminishing returns.
Also, Lorizean said:
Put the 64GB in and use it as a ramdisk. Be blown away by the speeds.
Which is better than caching for something like a temp directory.
This air-hybrid system uses nitrogen, hydraulic fluid, a hydraulic motor, and a couple of high-pressure tanks. I imagine it shouldn't cost much more than this flywheel, and it should store energy much longer.
If kids are in an intensive study program, then the intensive study program can afford to give the kids one-on-one attention and help them learn. If not, then in many cases parents are the only ones who can afford to give the kids one-on-one attention and help them learn.
On the other hand, the ASUS comes with a (small) SSD, RAM, and "a custom wireless ASUS Chrome keyboard and mouse that are collectively valued at $49." The NUC comes with none of those. Together those probably cost more than the $80 difference in price.
You'd be better off investing in more efficient coal-burning plants that cause less waste and less pollution, including GHG emissions, from the same unit of coal.
How about taking it one plant at a time? Make a list of the least efficient coal plants in the country. (Or, potentially, the world.) Buy them out and shut them down one at a time.
The industry then has the choice, in each case, of building a much more efficient coal plant, a much more efficient natural gas plant, or building a bunch of wind turbines, solar plants, or solar arrays. Any of which will substantially cut carbon emissions - though some more than others. Hopefully they'll start with the renewable and/or gas solutions. When they start building new coal plants, it might be time to re-think the strategy.
I've long thought this is an obvious application for electric vehicles, what with predictable routes and whatnot. Another one would be the small local delivery mail trucks, especially as those things are constantly stopping and starting - a very inefficient way to use an ICE, and one which puts a lot of wear on the engine.
A theory is science that's been proven one or more times. A law is science that was proven a very long time ago. But it seems like we need a name for settled theories.
I suggest a scientific "conviction". How do you get a conviction? You prove something beyond a reasonable doubt. Of course, a conviction can be overturned. One piece of solid evidence can do it. But there is strong reason to believe that for most convictions such evidence will never appear.

I'm a Liberal, and I accept GMO food. But I'm also a Slashdotter, so what I can't accept is patented GMO food.
I currently subscribe to a variant of this climate change theory. (Natural, not anthropogenic.)

Did they try putting an ad within an ad on this article about a star within a star?

You asked for it, you got it! Though the downside is these two fast cores don't include AVX, AVX2, or a few other instruction sets.
I'd even pay extra for a DRM-free version.
Maybe, but in that case you could simply get a NUC instead.
On one hand, an equivalent NUC is cheaper at $290.
On the other hand, the ASUS comes with a (small) SSD, RAM, and "a custom wireless ASUS Chrome keyboard and mouse that are collectively valued at $49." The NUC comes with none of those. Together those probably cost more than the $80 difference in price.
On the other hand, you could get a last-generation NUC with an i3 for $180.
On the other hand, there's a lower-end ASUS Chromebox, with a Celeron, RAM, and an SSD, also for $180. (No keyboard/mouse with this one.)
On the other hand, I'm running out of hands!
