>"I’ve come to think that the most fundamental problem with p-values is that no one can really say what they are."

Not surprising. The correct interpretation of p-values was not discovered until ~2 years ago. If you search around the internet you will find out that, according to the discoverer, he couldn't find a stats journal to publish it. The number of people who know the correct definition must be vanishingly small.

Thank god for arxiv, or I would have never understood p-values:

tldr: Calculating the p-value + sample size is a lossless compression algorithm. The thing being compressed is a likelihood function (way of describing effect size).

I could have just written this comment -- I spent the past two weeks doing the same thing, but in JS, and hit all of the same problems. In the end, I think API Gateway is more trouble than it's worth. I wish Lambda could have an exposed HTTP endpoint. Mapping all of the arguments in and out is so incredibly tedious when developing and things are changing fast.
Well, the planet was always going to heat up, it's just that we've accelerated the process.

What really bugs me about this whole certificate saga is this: Ok, so you messed up. But then we get this - to my ears - absolutely bogus spiel about this being for 'improved customer service'. I find it very hard to make that link. And then, to add insult to injury, after messing up like that there is no 'all hands' inside Dell to see if that 'mistake' (let's assume it really is a mistake, to be kind to them) had been made in more than one place, which in fact it is.

Once is normal, twice may be coincidence, thrice is enemy action. Let's hope for Dell that there won't be a third, and if there is that they spot it themselves before someone else does. And I'm not buying the line about 'improved customer service' even for a moment, you can't improve customer service by allowing anybody aware of this certificate to MITM any and all connections from these machines and even if that were the case it is just a little bit too convenient that such a mistake would also include the private key, which allows Dell to conveniently deny that they ever leaked the private key to anybody in particular (instead, they leaked it to the world at large).

Superfish was bad, this is in some ways just as bad or worse.

Now, Dell, can we please have a detailed technical explanation about why these two root certificates and their private keys were stashed on customers machines without their knowledge centering on specific functionality (as in what is that you could not do without these certificates and keys distributed) rather than some weasel worded techno babble about 'improved support'?
I'm surprised nobody has brought up the backlash against routine use of the p-value among scientists and journals. At least one journal has actually banned papers that report p-values:

Hybridization is this wierd fiction. It's trivially true because you can create any orbital via conservative linear combination of other orbitals, but only some of them will be energetically meaningful.

What hybridization would you expect water to have? You're wrong. It's not.

But our current qm are really bad at predicting bond angles. Vsepr is basically a geometric argument, and most of our understanding of bond angles is strictly emperical.
I was always thinking, if they let people in only via front doors, why they don't let the passengers from the back enter first. If people enter randomly, the ones in the front are blocking everyone else while they're putting their luggage in overhead lockers etc.

Maybe this is because of what you wrote :)
In what modern situation would a whole plane parachute actually help save lives? The vast majority of the (extremely rare) commercial aircraft disasters occur during takeoff or landing, when a parachute would provide little utility due to the distance the aircraft is from the ground. Other notable recent disasters had either instantaneous destruction of the aircraft (Metrojet 9268, Malaysian 17) or were caused by pilot error or murder/suicide (Germanwings 9525, Colgan 2407).

Perhaps the only incident I can think of where a parachute may have helped was US Airways 1549, where a bird strike caused loss of power to both engines. In that case, however, sufficient safety controls existed to enable landing on the Hudson river, and the aircraft functioned as designed (engines broke off when hitting water, the aircraft floated long enough to ensure safe evacuation of all passengers, life rafts deployed, etc). I would argue a parachute would probably have resulted in loss of life as a giant A320 parachute falling uncontrolled on to New York City would probably kill people crashing in to a building.

Rather than focus on superfluous, impractical safety measures, commercial aircraft designers have instead spent time on things that actually save lives, such as Traffic Avoidance and Ground Proximity warning systems.

Note that parachutes do exist for smaller planes, where the risks and benefits are substantially different. A good example is the Cirrus SR-22. It seems that most cases of deploying the parachute on the Cirrus is due to pilots running out of fuel, a failure which is extremely improbable in commercial aviation.
I find the underlying premise of this article and the claim that there is a "war on boys" absurd. It's a old argument from the same old set of people who have the same old intolerant (and dying) paradigm.

Only thing that should be surprising is it doesn't seem to be intentional: there is more than plausible deniabiliy here IMO.

OTOH Dell used to bundle adware openly around 2007 and a lot of manufacturers still bundle badware/scareware. (Yes, I'm talking about McAfee here.)
Let's say you want to fly from A->B. You research prices, and you find two options. There's a direct flight from A->B that costs $400, or you can take an indirect flight through distant hub C that costs $200. Is it unethical or wasteful to choose A->C->B for $200? I think all of us would do this without a second thought, aside from willingly paying more in exchange for less hassle.

Compare to hidden city ticketing. Instead of buying A->C->B, you buy A->B->C for $200 and then stop at B. It's no more wasteful than buying A->C->B, it's just more comfortable for you. In fact, it's slightly less wasteful, because there's a possibility that the airline could give your empty B->C seat to a standby passenger.

Assuming you don't have an ethical problem with the A->C->B hub flight, why would you have a problem with the A->B(->C) hidden city ticketing flight because of waste or disutility (or indeed anything else)?

I have no problem with price discrimination. But there are good and bad ways to do price discrimination. For example, one common method for flight discrimination is to charge less for tickets purchased farther in advance. Casual travelers typically book their travel well in advance, whereas business and other travelers willing to pay more typically book their travel shortly before they fly. This is just smart business, and it ensures that people who really need it can fly when they need to, but people who are more price sensitive can still travel. And you can't really game this system.

Then you have airlines trying stupid tricks like charging negative prices for certain legs. This is just wasteful and stupid. Why should I feel in any way obligated to support this sort of price discrimination? They are welcome to try such nonsense, of course, but their customers are likewise welcome to take advantage of it. It is not our responsibility to make their pricing scheme work. They're the ones who need to figure out workable pricing schemes.
Tinder and FaceMash = Dating Who You Deserve
I've taught at two colleges and based on my (purely) anecdotal experiences and attention to the climate, I'd say that the number of students and faculty interested in stifling or censoring ideas is small but also very, very noisy. They also have no sense of humor and college administrators as a group have no sense of humor or perspective, and they're chronically worried about accusations of indifference or insensitivity (which are themselves as good as convictions). There is a strong economic and career incentive for administrators to take everything seriously and to keep their heads down as much as possible.

Brew this up and one gets a majority of students who are reasonable but a small minority who drive all the discourse.

I don't teach at Yale and have never taught at Yale or schools with similar cultures, so I can't speak to the environment there, but William Deresiewicz did, and his book Excellent Sheep: The Miseducation of the American Elite and the Way to a Meaningful Life came out of that and I recommend it. His book A Jane Austen Education (http://jakeseliger.com/tag/a-jane-austen-education-how-six-n...) is also very good, even for someone like me who does not love Jane Austen.

Edit: Also, almost all of the censorship calls and nasty behavior / comments came from students on the left. Vox's "I'm a liberal professor, and my liberal students terrify me" (http://www.vox.com/2015/6/3/8706323/college-professor-afraid) is congruent with my experiences.

> Honest question: Why can't there just be non-profit banks?

There can be. If you mean, why can't there be "tax-exempt non-profit banks", the reason is because the tax code doesn't allow it (though no-capital-stock member-owned banks seem to be effectively untaxed, except on transactions subsidized by federal assistance to such banks, if they actually distribute their operating surplus to demand deposit accounts of the members.)

> We don't have non-profits deliver most services because they wouldn't be efficient and/or couldn't raise capital from investors.

If you are referring to "tax exempt non-profits", we don't have them deliver most services because there are limited categories in tax law of tax-exempt non-profits.

Possibly - not sure which cases have dealt specifically with national security letters and which have dealt with other aspects of the related programs. However there have definitely been cases which the government lost initially and then won on appeal, and as I've discussed on here before, I'm not convinced that inherently secret agencies will actually not do illegal things once they lose the case. They may still send letters to intimidate people and just won't be able to enforce it so easily. So the concept is still relevant IMO. We can't assume companies are allowed to disclose such backdoors if they exist.
I am not a fan of an appeal to authority, because I've seen people do worse in biomedical research.

To provide some balance regarding praise of USAA, they also push unnecessary and predatory "overdraft protection" and require an opt-out to binding arbitration. Some of their business practices as of the last three years have been converging with that of the big American retail banks. Some retail banks have made enormous strides in catching up to USAA's great internet and phone banking.

It would be great if someone were to include some information about their executive compensation plan to see how their incentives are aligned in comparison with the large retail banks.

Their insurance rates are very competitive and their customer service is stellar.

The fact that other people are free to speak against you does not mean that you can't speak freely.

Free speech does not mean freedom from having your speech acts criticized (quite the opposite; it includes freedom of others to criticize your speech acts.) And, yes, it means that your speech acts may affect your ability to hold a job where you are one of the major public faces of an organization (such as its CEO) and are not capable of dealing with the PR resulting from the association of those speech acts with a public face of the corporation (the same as it would if you couldn't deal with any other PR issue affecting the corporation, even if it wasn't resulting from your speech acts.)
That makes me never want to work with you.
I didn't downvote you, but I think other people are because the article's central thesis is that this social phenomenon is at its core neither radical politics nor anti-school protests. Rather, the article claims that it's merely a new coat of paint on the same old gang bullying/identity politics/being mean to outsiders to increase one's own social status.
iHeart, at least on Android, will download (using precious cell bandwidth) video ads and play them, during which time it disables the "back" button. You're forced to let the ad play. You can still switch to another app while this is going on, but IIRC you can't turn off the audio part of the ad by doing so. My "solution" when listening to iHeart is to keep the Android settings app running with the iHeart app selected, ready to "Force stop" it.
I pretty much agree with everything you say here. I wonder about the dissonance between "... a highly competitive market ..." and the narrative that there is a tech worker shortage. Sometimes I find the recruiters do people a disservice when they suggest candidates amp up the buzzwords on their resumes.

I'm pretty disappointed in the article and the comments, and how like Reddit this website is turning out to be. I'm not going to make any judgements (though I really really am), but this same article has been posted to 10 subreddits, among them such gems as: SJWsAtWork, ThisIsNotASafeSpace, sjsucks, and sjwhate.
I "read" tens of articles a day through various forms, but I wouldn't add up the words and equate it to reading books. Most of the articles I see are so padded with verbiage that they just get a quick skim - I like being exposed to the stories and ideas they contain, but I feel like if anything I'm trading the ability to deep-read like I do with technical literature for the ability to skim.

I guess my point is that it's pretty rare that I see an article that I think merits the sort of deep reading that the author is espousing (for reasons other than recreation, that is). Maybe that's just a function of the literature I expose myself to.

Observations do not imply truth. 0 and 1 are not probabilities, and in real life you can't prove something using observations in a logical sense. Real world runs on probabilities, not boolean logic.

In what way are airline seats scarce but wine is not?

Stuff like concerts is subject to scalping because the tickets get sold at below market value to avoid pissing people off. A concert venue may well sell out a popular show at $5,000 per ticket, but they won't charge that much because people will be angry. There is nothing like that going on in the airline (or wine) world.
> A bank pays taxes on profits, sure, but a credit union doesn't have profits

A credit union doesn't have "profits" because it is tax-exempt. Like banks they can, and do, run surpluses, which they return to members in the form of above-market interest rates on deposits or as dividends. If they lost tax-exempt status, they would have to pay taxes on the surplus before returning it to members, like banks do on profits before returning it to shareholders.

> better beyond the environment you created

That sounds like an interesting approach to life: Improve your environment; watch yourself improve; then repeat. It's like a big optimisation problem slowly working its way toward the maximum. It's like a personal singularity.

Sometimes I spend so much time in my head that I forget to change my environment. It would be nice if our best thoughts could somehow be put into effect more quickly without necessarily interrupting other planned activities. I guess that's where self-control and sequential execution come in. At the same time, the original plans may have become invalid.

Sometimes after you change your environment, it's like you have to re-compile the kernel before you can run the program you were initially planning to run. The trick is in not losing state information during that recompiling process. Sometimes writing cookies (aka, notes) can help here. Conversely, some changes are so big (or time-consuming) that your whole plan needs to be re-wired.

They say that teaching is one of the best ways to learn. My experience seems to confirm this advice. Perhaps when you go and explain something to someone else, not only do you organise and solidify the understanding in your own mind, but since you pull something out of your brain and stick it to the extended you (and beyond), that knowledge can take on a life of its own in the outer world. Your very awareness that the knowledge has been transmitted to the outer world seems to have a strengthening effect in your "inner you". It's as if the outer "awareness" links back to hidden parts of the inner you, as were it virtual dendrites connecting your brain to the collective consciousness.
>2. What p-values tell us isn't necessarily that interesting.

High p-value is the first thing to look at a study. If it's high, then you can simply assume the findings are unreliable. But if it's low, it doesn't yet mean anything.

The p-values allow you to discard worst mumbojumbo quickly. That might not be interesting, but it's valuable. The thing to remember is that "we don't know" =/ "untrue".
