This is a great study, for nutritional science I am very impressed with the methodology. It's very large and very thorough. It should be heavily noted that the goal of the study is not to create algorithms for healthy people, but for diabetic and pre-diabetic populations.

The only well supported long term consequences of post-prandial high glycemic response in otherwise healthy people is an increased psychological urge to eat. Outside of that, the importance of insulin levels in healthy people is extremely overhyped. These machine learning algorithms are cool, and may be useful for diabetic people, but for the general population monitoring your insulin levels is a waste of time.
> From where do you derive this certainty?

Physics.

> There's plenty of anecdotal evidence indicating significant variance among individuals.

However, research evidence disagrees. So, the most likely culprit in the variance reported anecdotally isn't different BMR or efficiency of digestion, but different (even delusional) calorie-counting approximations.
One interesting point about regression analysis though is that its outcome is perfectly fit to be exploited by marketing & advertising. explaining all the caveats of an experiment is hard, but saying that "people who eat X have less probability of getting cancer" is very powerful. So, in a way, I suspect these type of studies (regression) are "pulled" by marketing rather than pusghed by Research (at least for corporate sponsored studies)
How to Tell If You Should Get an Apple Watch [Infographic]
This doesn't sound like the same thing. Do you use an Emacs mode that is able to talk to the Pry REPL and retrieve information about the code you are working with?

In addition to the other stuff I mentioned, Geiser also gives me symbol autocompletion, automatically shows me the printed representation of the value under the point, shows me the signature for the current procedure I'm working with, and shows docstrings if I press a special key combo. Maybe I didn't make this clear in my previous post, but Geiser does all of these things in the source buffers themselves, not just in the REPL buffer. If there's anything resembling this for Ruby or JavaScript I would love to know about because those are the two languages I am paid to work with.

And all that stuff will still be exactly the same, whichever language you're working in. It will also probably still be there in ten years' time - or, if not, it will have changed only quite slowly in the meantime.

(I know some people like to shake themselves up by doing the text editor equivalent of putting their shoes on the wrong feet, then once they get used to that, switching to walking on their hands to stop themselves from getting too comfortable - but I'm not one of them.)

"That is, here was this new field called cognitive psychology, and I was really good at it, getting new ideas, and except for a few other people like Sigmund Freud and William James, who maybe had better ideas than I did, there wasn’t much competition. Licklider and Miller were… accepted me as an equal, and so you could say that my career was based on cowardice, or… or something. If there was a field where there were five or 10 people who were better at it, why bother? Because in these fields, you know, if you were a very good physicist and you ran across a Richard Feynman, what’s the use?"

Spicy food is unhealthy?
At what point in time is the cost of tooling written off in your view?

I'll grand you the $2600 price tag if you also tack on the 400K for the house to keep the setup dry and you assert that the creator only ever uses the laptop for this specific purpose.

You can't factor in costs like that and then critique the DIY project because of it. I'm sorry, that's just not fair.
"But not the whole thing. I could make conscious choices to make my body healthier. But I don't, and therefore I can accept at least a little bit of the blame."

I think this is the sad truth of the matter (at least for now). People tend to fall into one of two camps: 1) Those who believe that obesity is largely (if not entirely) the obese person's fault; 2) Those who believe that obesity is heavily influenced by factors outside of conscious control, and therefore, there's nothing to be done about it.

The truth is somewhere in the middle. Some people are luckier than others, genetically or epigenetically. The unlucky ones will put on fat more easily, and they will have a much harder time losing it. So that means they need to work twice as hard (if not 100x as hard) to keep it off. It's a shitty break, but it's the truth.

I grew up fat. Losing that fat took nothing short of a Herculean (and borderline unsustainable) dietary effort. I mean, I lived like an ascetic monk, depriving myself of any and all pleasurable food, for the better part of a decade. I worked out like a crazy person. And even today, keeping off the fat requires a constant vigil over everything I eat, and the amount of exercise I do. I wasn't responsible for getting fat in the first place -- I lost a prenatal dice roll -- but I did take responsibility for battling the bulge.

"Continually reiterating the thermodynamic dietary hypothesis to me (energy eaten minus energy expended) does not help. I doubt it helps anyone except possibly those who do not already know what a kilocalorie is."

Agreed. It's also willfully reductionist, and it smacks of passive-aggressive moralizing. To me, rattling off the calories-in-calories-out line is no more helpful than calling obese people lazy, stupid, irresponsible, or sinful. (And in basically 90% of the contexts in which someone says it, that's the subtextual insinuation.) It's unproductive. It's an attempt to close the case summarily, and this case needs to stay open.

The perfect “throw”
Nutritional panel information is not an in vivo measurement.

If you put 100g of broccoli in a bomb calorimeter and burn it in pure oxygen, you heat it up by 34 kilocalories.

If you put it in a human digestive tract instead , the human can absorb anywhere from 0 to 34 kilocalories of food energy from it. We already have ample evidence that the food energy absorbed may be affected by the microbiome in the intestines, the preparation method used, the time of day, the time of year, and other foods that may have been eaten at around the same time.

But the calorimetry does establish a hard upper limit on absorbable food energy.

This is why non-ruminant herbivores with shorter digestive tracts--like the arctic hare--will engage in coprophagy. They will eat their "first-through" turds, because there is still some food energy in them. Ruminants do essentially the same thing with multiple stomachs and regurgitation.

If you aren't weighing your food and burning your poop in a calorimeter, you are inaccurately reporting your caloric intake. Even then, you can't really know for sure how much of that energy was absorbed for use by human cells, and how much was used to sustain your microbiome.
From the article, it appears adoption of PTC has been hampered by Amtrak developing it's own system, funding issues and slow approval from the FCC:

"In much of Asia and Europe, engineers are protected by a technology known in the United States as positive train control, or P.T.C. Connected by digital radio waves or GPS signals, P.T.C. transponders in the track maintain constant contact with computers in the cabs of oncoming trains. If the transponders determine a train is traveling too fast, the locomotive’s brakes are triggered automatically. Amtrak has been working on its own in-house version of P.T.C., called the Advanced Civil Speed Enforcement System, or Acses, for almost a decade. But owing to insufficient funding and a row with the F.C.C., which Amtrak said had been slow to approve the use of the requisite radio bandwidth, its actual implementation has been piecemeal."

Later on in the article it confirms that PTC has been rolled out on the line where the accident occurred, but a national rollout out will potentially take until 2020:

"In late May, Joseph Boardman, Amtrak’s C.E.O. and president, promised that the installation of P.T.C. on the Northeast Corridor would be completed by the end of 2015, a pledge he has kept: Today, the system is active on all routes, with the exception of substantial stretches of track owned by the State of Connecticut. (A spokesman for the Connecticut Department of Transportation said it hoped to have P.T.C. installed on all state-owned track by 2018.)
It will be some time before a national rollout is complete. In November, President Obama signed into law an extension to the Rail Safety Improvement Act of 2008, giving railroad companies — which had complained about the cost of implementation — until 2020 to bring the technology online."
It's a neanderthal idea to determine whether or not you're going to hire/promote/review a candidate based on what plumbing is in their pants.

Acknowledging the 'issue' you described above isn't taking a brave stance against overreaching feminism. It is actually illegal. Not to say that people don't do it all the time. (Yay, at-will employment!)

This conversation is actually a perfect illustration of how one aspect of gender-based discrimination works.

And if we're going to talk about speaking statistically, according to the Disparate Impact clause, if whatever criteria you use for employment happens to statistically discriminate against a protected class, what you're doing is also illegal.

(And while we're here, black people are more likely to get arrested, and Russians are more likely to be alcoholics. I'll be sure to mention that the next time hiring is under debate.)
Because it was asked for, I would be willing to provide feedback, but packaged as an iOS app...or probably an Android app...creates a high level of friction.

The NDK is not part of their priorities indeed (although to be fair it seems that things are slowly getting better with a team dedicated to integrating Clion).

They are smart engineers though and I have no doubt that if C++ had been the best choice for the platform, we would not be writing apps in java ...

tbh, I am really tired of the simplistic 'because java' argument with nothing to back it up ...

I have no love for the language (although I think it gets more flak than it deserves) but I have spent a lot of time working on the performances of Android apps and none of the issues I have fixed would have been any different in another language.
Whitelisting has been the silver bullet at lots of places I have worked. It is intuitively attractive. It is intuitive that your employees will only need a small subset of websites to do their job.

I was just wondering what everyone else thought.

Probably an oversimplification on my part but it seems like OpenShift is nice enterprise friendly features sprinkled on top of Kubernetes. Which is no small thing, they've contributed quite a few patches to Kubernetes that are critical for a lot of enterprises. And a read/write GUI shouldn't be a hard requirement these days but a lot of big companies have this ingrained habit of treating IT like a commodity and subsequently hire people that are so uncomfortable with the CLI they're openly hostile to the idea of even touching it.

Then there's command and control. OpenShift seems to be more friendly to keeping things under someone's thumb. In an ideal world people would use Kubernetes the way Google uses Borg and devs would be trusted the way they are at Google. But between corporate fiefdoms and the aforementioned hiring practices many companies are still very far from that ideal.

As cool as spacemacs is, there are some pain points with it. Try following the documentation to add the mega theme pack. Insert the line that the docs say to insert. (into the file in which they tell you to insert it) Restart Emacs, find yourself stuck in pure emacs. Google how to exit emacs... or open a file and edit it. (If you have no experience with Emacs previously) Yes this is a doc issue, but the point is any misconfiguration, and you find yourself without any Vim-ishness at all.

This makes Emacs great. It is a night and day difference. Multiple times I've tried to transition to Emacswithout it and just couldn't see why people love it. Spacemacs is a great default distribution and solves some major pain points of initial setup and "sane" defaults. There's still a couple things that I'm not quite hip with (installing new 'layers' without restarting, among a few others), but it's probably because I don't know enough about it yet.
