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!

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?!

It apparently only happens if you read the same bytes from RAM 139,000 times in 64 milliseconds. If your program is doing that, you probably have a lot more to worry about than disk corruption.

If this was actually happening in the real world, computers would probably be crashing every few minutes.

No. These are standard instructions that many apps require to function correctly when using multiple threads.

Can you explain when you'd need to flush the cache when using multiple threads? You'd have to flush the cache back to RAM (isn't that a privileged instruction?), invalidate it, then read the data back from RAM. That's surely insanely slow compared to just using the CPU's internal cache coherency mechanisms?

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.

Economic inequality is just getting back to its historical levels.

If I remember correctly, the historical norm is that 20% of people have about 80% of the wealth. It's worse than that today because the government steal so much money from the middle class (or just print it) to give to the rich.

But, hey, elect more Liberals, they'll sort it out. Ha-ha.

Liberals tend to believe that one of the government's jobs is to make things better for the jobless, the disenfranchised, the dispossessed, the poor, the hungry, and the downtrodden, so he's pushed programs that aim to help such folks.

You're funny. If Liberal policies really stopped those folks being disenfranchised, dispossessed, poor, hungry and downtrodden... they'd stop voting Liberal. That's why the real-world policies are designed to entrap those foilks into dependency on the Glorious Liberal State, so they'll keep voting for the politicians who are supposedly 'helping' them.

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.

GDP comparisons:

Major pro-sanctions players:

EU: 17,5T
Japan: 4,9T

Major anti-sanctions players:
Russia: 2,1T
China: 9,5T

Just ignoring the whole fiat currency issue and controlling the global banking system which act as large multipliers, China is simply not comparable to the economic pressure being levied against Russia.
