Not every hunter-gatherer got crushed by a mastodon either - that doesn't mean it wasn't a selective factor in tribes that hunted them.
But it does raise a serious issue - they're studying changes that don't necessarily reflect the selective pressures of present-day life.
Think about it: what are the leading causes of death for people in the prime breeding age (15-34)? Car accidents - by a good margin. So isn't this significant selective pressure to beef up the neck against whiplash, the skull against forehead impact, survival during significant blood loss, etc?
#2 is suicide. I don't know how this rate has changed over time or whether the methods modern humans choose for attempts are more effective than would have been chosen in the past. For example, while men commonly turn to firearms, which are a very effective way to commit suicide, women more often turn to prescription medication overdoses as a method, which overwhelmingly fails.
#3 is poisoning. While humans have always been around poisons, the sheer number that we keep in our houses, most of types that we didn't evolve to, suggests that this may be a stronger selective factor now than it was during our agrarian days, perhaps comparable to that when we were hunter-gatherers or worse.
#4 is homicide. We've definitely gotten a lot better at that, a person is far more likely to die from an intentional gunshot wound than a beating or stabbing. Selective pressures: surviving blood loss, mainly. Stronger, thicker bones may help in against low velocity penetrations.
#5 is other injuries. Again, we're not as likely to suffer from, say "crushed by a mastodon" as an injury, but we've developed plenty of new ways to get killed or maimed in our modern lives.
Then it gets more complicated on the basis that the issue isn't just about survival of the individual, but their social group as a whole, so even nonbreeding members can have a major impact...
To make a political statement? Since when was this "a political statement"? It was an attempt to stop a movie that made fun of the Great Leader. An attempt that mostly succeeded. Which was done after previously threatening Sony about the issue.
What, exactly, is to gain by admitting culpability? Is that usually what criminals do? "Why, yes, officer! I threw the brick through my ex's window to get back at her and scare her. I'm telling you now so that you can go ahead and punish me!"
Because the world is just full of people who would hack a company to blackmail them not to release a movie about Kim Jong Un. Because everyone loves the Great Leader! His family's personality cult^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^HVoluntary Praise Actions only take up about 1/3rd of the North Korean budget. And I mean, they totally deserve it. I mean, did you know that his father was the world's greatest golf player who never had to defecate and whose birth was fortold by a swallow and heralded by a new star in the sky?
No, of course it wasn't North Korea. Clearly it was the work of America! Because America wants nothing more than a conflict with North Korea right now. Because clearly Russia and Syria and ISIS aren't enough, no, the US obviously has nothing better to do than to try to stir up things out of the blue with the Hollywood obsessed leader of a cult state whose family has gone so far as to kidnap filmmakers and force them to make movies for him. It all just makes so damn much sense!
Cue the conspiracy theorists in three, two, one...
I know, write? Who gives a flying flip about an app to track a jolly magical man with an eating disorder.
Now, if someone would make an app to track the Yule Cat, Grýla, and her progeny, then that I would have interest in!
Duh!!! Does Apple really want shakeup an already tenuous "blessing" by the Chinese government? Never mind the fact the Chinese App store is mucked up and certain featured not available. That's a BILLION consumer potential market they don't want to miss out on.
In my personal experience of "benchmark queens" in general; be it automotive performance or computing, are all about the synthetic numbers and zero basis on practicality (let alone value in cost). If a gamer is doesn't give a toss about a particular core subset of general computing (Video, CPU, RAM, and Storage), they're not benchmark queens. I've met plenty online who are. And when queens start debating online over numbers, the flamewars begin.
Ouch! Seriously bad. Worse than the Pentium FPU bug (and that's bad). What good is a computer if you can't rely on the data being committed back to disk because of corruption mid-flight in RAM?! At least with the FPU bug, it was only FPU. But here we're talking about an industry wide issue where any operation cannot guaranty data doesn't become corrupted back to disk. By the time bit-rot sets in, you may have to dive into your grandfather-father-son backup archive. And that's assuming such a backup scheme is being used by those who are effected. Shit, that's assuming people are even backing up their data in the first place!!
True, and commodity chips not to exact spec will introduce disturbance errors. But apparently this is been a known problem with DRAM with various method of mitigation during the binning process. It's just that density and tolerances have become so tight that the issue is now exasperated. I wouldn't be surprised at all if those 19 models also had a few that failed if tested again and again.
Honest. General computing from low-end PCs, phones, and other devices are long overdue in employing ECC by default. So you lose capacity and tiny performance hit. BFD if that means your data doesn't become corrupted. The only people that would care are the PC gaming benchmark queens.
According to the paper, EEC only reduces but does not eliminate the problem (section 6.3). Multiple bits can be corrupted at once.
If you're wanting to narrow it down, you won't like this line from the paper:
In particular, all modules manufactured in the past two years (2012 and 2013) were vulnerable,
It's pretty clever, and something I always wondered whether would be possible. They're exploiting the fact that DRAM rows need to be read every so often to refresh them because they leak charge, and eventually would fall below the noise threshold and be unreadable. Their exploit works by running code that - by heavily, cyclicly reading rows - makes adjacent rows leak faster than expected, leading to them falling below the noise threshold before they get refreshed.
FTFP. "We induce errors in most DRAM modules (110 out of 129) from three major DRAM manufacturers."
Short version, leakage current from adjacent gates can nudge other to bit-flip. I don't think this is a manufacturing problem as it is a fundamental EE design oversight. So yeah, defective by design (unintentionally)!!
Well only because you mentioned it, the rainbow blotch in the middle is distracting. Would prefer just the red/black image by itself
Russia imports processed foods *and* staples. Just because there's some products that they're net positive on doesn't change that picture, their food imports are about 6x larger than their exports. And even some of your examples are off. For example, Russia exports a couple hundred million dollars of milk every year but imports 1 1/2 *billion* worth.
Russia's top ag imports are beef, beverges, pork, milk, tobacco, sugar and honey, poultry, and cheese. Beverages is mainly alcohol. So take beverages and tobacco out of the picture, you've still got mostly staples. And the funny thing is, see the milk and all that meat on the list? Russia's biggest subsidies to its ag industry are *already* on its meat and dairy production, and it still vastly underproduces.
It should also be noted that the very thing that keeps Russia's ag industry competitive at all has been its steady shift from lousy Soviet-era farm equipment to modern equipment. The vast majority of which (and spare parts to keep current systems operational) are imported.
To the victor goes the spoils, as they say.
Castro's revolution was predicated on creating a New democratic government; instead he shut the door behind him with communism. Fact is, reality isn't a morality tale. Often the bad guys really do win.
