> only 11 percent. this tells us that the remainder is more likely to be attributable to environmental factors.

No, it doesn't. It merely tells us that with the data up to now, we've reached 11% (up from, incidentally, ~0.3% just 5 years ago). It provides a very loose lower bound on genes. Saying that is like saying, 'our software testing up to now has only revealed bugs in 11 places, therefore, every other line of code must be bug-free!' Even if you knew nothing about the actual heritability estimates, one would think that finding so much so quickly would make one suspect that there's a lot more to find...
The technique of choice for this is catharsis. This is why watching and reading tragic media is so useful to people. It's tailor made to engage the limbic system. Watching people deal with really awful situations primes the mind to release emotional energy and engages neural pathways that aren't often active.

Mindfulness is useful for when you have uncontrolled emotions flooding your forebrain and making it difficult for you to function. Forcing your mind to watch the processes as they're happening allows the forebrain to come up with novel ways to make sense of what the rest of the brain is doing.

You want to release, then integrate emotion. Catharsis, then mindfulness.

There isn't an easy or quick fix for it. Though there are small towns in America that are predominantly Muslim (lots of refugees relocated to specific locations). But this is completely reasonable: if I were an ex-pat living abroad, it would also be hard to raise my children in an area where they would be the only white Christians. That is a real trade off that is hard to account for outside of certain pockets within the US.

I think Anti-Semitism is fairly rare (though it does exist). But it would be hard being one of the five Jewish families in my entire high school. I was good friends with them, and Christmas was a hard time for them. It would be very challenging to be a Muslim in good parts of America (outside of major cities; where, if we're being honest, it still isn't easy being Muslim).

Nutritional science is very hard for a variety of reasons, including due to experimental deficiencies and political motivations. But that doesn't mean people should ignore articles like this.

It's an unfortunate reality that Americans must deal with the fact that the food industry has a massive amount of influence over the FDA and USDA, and historically, the industry has used this clout to preserve their profit margins as the expense of our health and well-being. An example of this is the "food pyramid" whose 2011 replacement MyPlate is still not terribly accurate.

It can take years of studies like these to pressure law makers into forcing scientific consensus onto an industry who firmly believes the FDA is there to put them out of business. Without articles like this, it's unlikely that Congress would ever both to address issues with our food supply.
The interesting meta-point here is the chicken-egg problem between cheap robotic hardware and large-scale data collection.

We don't have general-purpose robotics because there aren't enough robots being built for them to become cheap.

And the robots can't do anything in the real world because they cost too much for someone to gather 1m hours of training data.

Presumably this is the Softbank game plan -- build a ton of general-purpose robotic hardware platforms, and hope that they (or another group) figures out how to build general-purpose algorithms in the next few years.

It's a calculated risk that Softbank have the resources to bankroll.

Ask HN: What is the normal distribution of scale?
It's common for this to be measured in Requests per Second (RPS) or Queries per Second (QPS).
When most people think of services at scale, they think of Google, or more specifically Search. Which does greater than 40k RPS [1], though that number is difficult to identify since it's made up of many subsystems and internal services.[2]

But then there are also IoT platforms that ingest maybe an order of magnitude more requests.

Those services likely fall outside the 99.7% or three standard deviations of all services that receive traffic.

What would you expect the volume of traffic to be for other standard deviations? For example how many would fall within 10k RPS? 95%? And what would you expect the mean to be?

If we extend this to socket-based communication, such as some games, would these numbers change?

Advice is sort of the first derivative of what you should be making decisions based off, i.e.:

- How have people solved similar problems in the past? How have things gone wrong for people facing similar issues?

- How is the world different now? How is the world going to look in five and ten years?

IMHO advice is only useful to the extent that you can deconstruct the thought process behind it.

From the discussion:

> However, theoretical projections that failed to consider heterogeneity of effect sizes were optimistic Our and others’ findings suggest that imperfect genetic correlation across cohorts will be the norm for phenotypes, such as educational attainment, that are environmentally contingent.

So it is somewhat worrying that genetics predict the clearly environmentally contingent like educational attainment better than "cognitive performance."

> Our results also highlight two caveats to the use of the polygenic scores in research. First, our within-family analyses suggest that GWAS estimates may overstate the causal effect sizes: if educational attainment-increasing genotypes are associated with parental educational attainment-increasing genotypes, which are in turn associated with rearing environments that promote educational attainment, then failure to control for rearing environment will bias GWAS estimates.

That is a very complicated way of saying that some genes express themselves by black skin, and these genes have a strong effect on funds available to the school.
Would this increase the humidity of the local biome? Should we avoid using it in deserts?

Filling the tanks with Earth-sourced water would mean Earth bacteria, tardigrades, etc. The bacteria that stuck to the side of the tank, instead of being pulled out with the water-fuel, would reproduce once the tank is refilled from extraterrestrial (sterile) ice & water sources.

Could this be a cheap and dirty way of kickstarting terraforming? By landing and taking off on a planet like Mars with this engine, the steam exhaust would contain some of the bacteria and other denizens of the tank, some of which could be anaerobic. And this mixture could easily be intentional. The engine's steam exhaust could condense into a cloud of bacteria, and even precipitate to the surface.

Or the space ship could just have a sticker on the water-fuel tank door that says: Only use (sterile) space ice. No planetary ice.
The "pressure stall information" looks interesting. It's exponentially weighted moving averages of the fraction of time "some" or "full" (all non-idle) tasks are stalled on each of CPU, memory, and IO. Also a counter of absolute time. [1]

Printing this seems like a good addition to "Linux Performance Analysis in 60,000 Milliseconds". [2] More useful that the load average printed by uptime, which hasn't aged well. Linux mixes cpu-bound and io-bound stuff into one bucket [3] which is a terrible idea, and the number of tasks is confusing at best when you have a mix of thread-per-CPU and thread-per-connection stuff running.

Looks like it's also exported on a per-cgroups basis, which is great.

Don't buy anything you need to trust from Amazon, especially when it's stuff that is easy to manipulate and/or easy to make a counterfeit of. Amazon puts everything that claims to be the same product into a single bin and if somebody sends Amazon counterfeited Yubico products, they will be delivered to anybody that buys a Yubico product, even when the seller they are buying from made sure to only send verified ones to Amazon.

This obviously only applies to products that are being shipped with "Fulfilled by Amazon".

Which was agreed by the Scottish parliament. Either way, nobody involved in those decisions is alive now, so it's all ancient history, as is the French invasion of the island in 1066.

I'm not sure how (the op) can complain that the United Kingdom of Great Britain and Northern Ireland's claim on Scotland is "tenuous", and more than "it's claim" on Norfolk, Kent, or Birmingham.

If a clear and sustained majority of the people living in Scotland really want to be a separate country, that's fine.
If a clear and sustained majority of the people living in Norfolk really want to be a separate country, that's fine.
If a clear and sustained majority of the people living in Hull really want to be a separate country, that's fine.

There's no "claim" other than we agree as a democracy to band together to govern us, and protect us, and enable us to live our lives. If that doesn't work out for a given region, that's fine.

I'm sympathetic to this position, but I don't know if it's the whole story. Russia, before the revolution, was a country of extremes. On the one hand, there were farmers who were living in a similar manner to 5th century peasants. On the other, there were some of the largest industrial complexes in the world.

I think the Soviets did achieve incredible things, but I think that's largely the result of abandoning profit as the sole criterion of whether an activity is worthwhile: capitalist societies tend to spend most of their productive labour on keeping profitable hamster-wheels spinning (like the housing market, for instance).

Yeah. I agree.

Maybe this makes it slightly less bad: to log into my account, the guy typed in a single-use random code which their special administrative interface texted to my phone. Assuming that code is truly only good for one use, there's a little safety in that.

But, I still wonder what exactly these cell-phone representatives do with the info they can access on my account, and whether they truly log off, or capture that web page's info somehow, etc.

I once saw a cell phone rep in-training take a picture of such a private account screen with their personal phone and then text it to another person in the company so that they could ask that person how to carry out the next step in the sequence of screens they needed to fill out. It was pretty disturbing.
