I don't understand what your point is, coaches are precisely an example of a boss having deep understanding of the work being done, as opposed to being hired purely for his people-management skills. You don't poach the manager of a retail chain to be your basketball coach.

Obviously a coach can't replace a player on the field, that's primarily because playing is more important and pays better than coaching at the top level, so no sports star wants to be "promoted" to a coach, they will coach once they can no longer play. And even then, being a coach is not necessarily the life goal for super-rich star athletes. It's a downgrade from what they used to be in their prime.

Null hypothesis significance testing. It is a "method" of statistics that resulted from confusion between Ronald Fisher's significance testing with Jerzy Neyman and Egon Pearson's hypothesis testing sometime in the 1940s. None of those three are free of blame either.

While there is all sorts of things wrong with NHST, the primary thing is that researchers never actually test their own hypothesis. Instead they test a "null" hypothesis that acts as a strawman, usually that some parameter equals exactly zero. Then when the strawman is "rejected", they go on to say the results support whatever theory/idea it is they favor.

Rather than come up with precise predictions deduced from their idea, they leave them vague (If I am right, A will be correlated with B). Then calculations are used to reject the very precise strawman, giving an entirely false sense of rigor to a handwavy, nonsensical ritual.

It is very common, and seems to get more and more popular every year despite all efforts by scientists and statisticians to stop it (because it lets you seem scientific about proving whatever you want). I was trained to think that way myself not too long ago, with absolutely zero mention of any controversy.

>The republican party is simply unacceptable on many levels for any intelligent, honest person.

Anyone who would say this with a straight face isn't intelligent or isn't honest, so they can't speak for intelligent honest people.

>but most of us don't.

Who exactly do you think you are speaking for? Identity politics and strong liberal populations in universities has made it social suicide for anyone to admit they have any doubts about the Democratic party.

>We wouldn't be allowed to run as a republican if we were 'fiscally conservative' but felt that gays should be treated as people

The situation in Greece and various other European countries seems to suggest you can't buy your way out of a recession with entitlements either. You'll find very little evidence supporting the efficacy of any system that translates well to the US, which has the irritating job of being the entire Western World's military.

For what it's worth, within the last month, I've touched rails 3.2, 4.0, 4.1, 5.0, and 5.0.1 apps which are running in production. It's possible to maintain these apps on old releases, but the idea of never upgrading will be painful in the end.
This argument always comes up but I'm not convinced. In society people tend to congregate in professions and social where people have similar intellectual capabilities. How many people here were interested in a career in Software Engineering because the people in it had similar interests and values to you? I know I was.

Sure you need to be able to talk to other groups of people but not to the extent that you require 35 hours a week of education along side them for years. Additionally I'm not sure being educated alongside them actually helps. There are a a hell of a lot of intelligent people who become resentful of that situation and that attitude can take years to mature out of, if they ever do.

My guess would be strict quality controls on each individual battery combined with a sophisticated battery management system.

I've long thought that one of the reasons Tesla built their own battery factory is so they can be absolutely assured of the consistency of the batteries. If the charge rate, discharge rate or internal resistance of an individual battery varies from the others over time, that's when battery packs tend to catch fire. Well, one of the reasons battery packs tend to catch fire, anyway.

Self-driving electric cars are especially well suited to tunnels. Self driving means higher capacity (higher speeds and less space between cars), fewer accidents, narrower lanes (better tolerances than humans), and electric means less tunnel ventilation needed. Cost per passenger mile should be considerably lower than existing tunnels. Even better if you can bring technological deflation to tunnel construction.

Populism was dealt with by way of the electoral college.
I remember my decision making process:

It seemed to me that if I took the dual/early enrollment college course that I would definitely get the credit, whereas the AP course would actually require far more repetitive homework, lots more class time (which I didn't want to do), and only then would I have a chance to qualify for college credit.

That's a no-brainer, in my book, but so many of my peers refused to follow my lead to the University when I tried to persuade them.

In spite of lots of sales training, I've never been a good salesman.
It isn't inexplicable. NHST entails affirming the consequent and transposing the conditional, which are known formal fallacies.
As a S/W dev who started 30 years ago and finished his MSCS 27 years ago, I totally agree - S/W engineering (SWE) today is NOTHING like it was in the 1980s. SWE then was seen as mainstream CS and often a required part of a CS degree. Today, CS profs working in SWE are rara aves.

SWE's desiderata then was to become an engineering process, where components were marshalled into a formal blueprint, and only THEN did implementation begin. And when implementatione ended, only THEN did testing begin. And only pro TESTERs do the testing. And only pro librarians did the project configuring and building and SCCS control and S/W maintenance and releasing.

Much of today's SWE is subsumed by the choice of programming tools, esp the language: its innate constraints its object model, its hierarchical library interdependence, and the sundry constraints & guidelines these impose.

In 1985 there was a LOT of discussion of how to introduce more proscriptive programming models as ways to shape how programmers think and design and implement. Today most of that discussion is moot, since most prog. languages implicitly enforce most of that (implementation) proscription. And where voids exist (as in design), language convention and idiom (and community bias) tend to step in to constrain choice to shape thought and close the loop.

No, I think SWE has changed enormously since the antedeluvian world views that wrought the invention of Ada or Beck's first writing on Agility. Perhaps for S/W devs under age ~50, who grew up in the mature world of OOPLs, unit testing, and 'Agile uber alles', that form of SWE seems to be inviolate and have existed since time began, perhaps discovered on clay tablets in an ancient Ark. But no...

Honestly I think that school is state sponsored babysitting. Once you understand that, the rhetoric teachers are often spouting about "misbehavior" "defiance" and "insubordination" all makes sense. At school a child's job is to not make a stir.

I also think free public school is critical to having an educated productive populace.

There's an apparent disconnect between my first opinion and the second. That disconnect is, and I know this will sound trite, questioning authority and facts. It's a critically important practice that schools actively discourage.
The notion that not having proper tail calls aids debugging always seemed like a post-hoc justification. The stack trace of an iterative function will lack exactly the same intermediate evaluation frames as a tail-recursive implementation.
There isn't one. A scientist (a non-quack one at least) running on the Republican ticket would be wasting his time. The Republican voters do not care for science (esp. anything that contradicts their worldview), and insist on anyone they vote for being highly and openly religious. That's not going to work too well for scientists, even if they were fiscally conservative.
All of that is true, and I nearly entirely agree. I hope we find a better system.

But it's not slavery because you are not forced to produce on threat of death. My issue was the devaluation of the term "slavery", not the legitimacy of the confiscation. If you consider it entirely illegitimate, then what was described is armed robbery.

Despite all the celebration, the Dow Jones industrial average has not hit record highs recently. If you adjust for inflation, the highs just aren't as high as they seem.

And even if it does hit a real, inflation-adjusted high in the next few weeks, it won't mean much. The Dow is a seriously flawed stock index, and it's certainly not a good way to measure what's going on in the overall economy.

On today's show, we rain on the Dow's parade and explain why a lot of very smart people say we should ignore the Dow.

Octopart’s Key Takeaways from IoT Day
I agree in that people who still appreciate truth and facts must combat lies on all fronts, and that includes on the cultural front of entertainment. If a joke can reveal that the emperor has no clothes, I suppose that's a net gain. But this is a double-edged sword because it has the danger of dimming perceptions of what's really at stake. Yes we should laugh at the naked fool in charge, but if all we do is laugh, that just makes him a powerful naked fool.
As a former scientist who is very sad about the way politics are going right now, I was extremely excited to see this group forming. Then I saw that they've inexplicably co-mingled gun control and science. By all means we need to take every measure possible on climate change, energy production, and science education (the other issues listed on their site), but scientists are no better suited to have an opinion on gun control than any other citizen (except some of them might have a slightly better understanding of statistics, but those can lie in either direction).
I guess I have to be a little bit contrarian. Of course we want our managers to have good technical fluency and to not have to have everything explained to them. It's necessary but insufficient. The skill set of a good manager is different from the skill set of a good individual contributor. I've worked with way too many engineering managers who were great engineers but needed a lot of coaching in order to manage well. At lots of tech companies, you get managers this way: Roger is "smarter than the average bear" and we want to reward smart people, and the only promotion we know is management, so congratulations: Roger is now a manager! Go manage people, Roger! Go understand the business implications of your team's work. Go communicate effectively with execs. Go write a project plan. It's not that Roger is stupid--far from it, its that he is now in a role that requires a totally different skill set.
How about addressing the widespread concerns that cause "populism" even if it means setting back your own ulterior agenda?

Brexit and immigration is a good example of this. Blair decided mass immigration was a good idea for a number of reasons. At some point they surely realised that although it would provide an economic boost, some people would lose out financially and most did not want significant cultural change in their community. Over the years larger dissatisfaction with this policy grew and grew, only to be labelled racist by the ruling parties. This led to UKIP which led to splits in the Conservative party which led to Brexit.

Ignore a valid issue long enough and resentment will spread across the country. If these peoples concerns and wishes were not sacrificed for ulterior motives a EU ref would likely never occur.

Parallels to US/Trump seem reasonable. Large groups of people whose concerns have not necessarily been address because the contrary policies benefit an already privileged and distant few.

tldr: Offer real solutions to the large number of poor and struggling people in your country. Even if it slows down your grander plan. If you don't, resentment will build and there are more of them than you.

edit: The absolute biggest danger to the embedded powers is that Trump succeeds and does a good job. Hard to overstate this.
> I say the idea of the destruction of truth was more important than the methods anyway

I agree. I'm appalled that Trump feels free to lie about something as falsifiable as the weather (https://www.nytimes.com/2017/01/22/us/politics/president-tru...). And it does make me worry about totalitarianism.

But in American culture, the use of "alternative facts" is hardly an invention of the government. Postmodernism made deep inroads into the thinking of average people. "What's true for you" or "true for me" became a common idea in religious conversations. And it extends into our debates about things like gender.

When everyone is allowed to have their own facts, we can quarrel, but we can't debate, because we have no common assumptions. And if we can settle anything by debate, coercion is the only option.

It's an intellectual environment ripe for authoritarianism. But not created by it.
What will happen to the Dow (and other indices) when the first serious geopolitical or financial crisis hits?
I suspect that some gifted kids would benefit from it and others would not and that whether or not a child should go to a separate school should be determined on an individual basis.
At elite schools in the US, the money spent on college is not the significant gap between those from wealthy or poor families, but the money spent before college (i.e., the background experiences they come in with) and the money spent outside of college (i.e., the experiences you can't engage in while your there.)

To be clear, affording college is a real struggle for lots of Americans, but if you get into a top Ivy school, it's usually a much smaller burden than a second-tier one. They have big financial aid programs; I have a friend going to Harvard from a lower-class background, and their tuition is essentially nothing, but they feel extremely out of place.

Good information on the chain of decisions that set up Apollo 1 for the disaster:

"Why Did NASA Still Use Pure Oxygen After the Apollo 1 Fire?"
http://www.popsci.com/why-did-nasa-still-use-pure-oxygen-aft...

(Warning: Horrible crap foisted on you via Javascript if you have that enabled.)

tl;dr:

1. Designed Apollo to used a mixed gas (nitrogen/oxygen) atmosphere.

2. Needed weight savings. Mixed gas requires complicated, heavier, support.

3. NASA changed to pure oxygen over the objection of the North American Aviation engineers.

Justification:

a. Pure oxygen was used in the past with no disasters.

b. The pressure in orbit was 5psi. At 5psi, fires are controllable.

4. Launch pad test with a closed hatch required atmospheric pressure + 5psi to get the differential pressure of space.

5. Spark + high pressure oxygen + fuel = disaster.

Added: There were a lot more contributing factors such as the schedule pressure (wiring issues probably caused the spark) and the lack of explosive bolts on the hatch which prevented the astronauts from escaping quickly.

Bonus tl;dr on the resolution:

They pressurized the capsule with nitrogen/oxygen on the pad, so it was safe (other than being on top of a massive bomb). As the capsule ascended, they bled off the nitrogen/oxygen atmosphere to maintain the 5psi differential pressure (the astronauts were breathing oxygen via their space suits so it did not matter to them). Once they were in space, the atmosphere was maintained with pure oxygen at +5psi.
You have a point.

A modest clandestine bunker close to but not directly in a population centre might fare a lot better than these pinatas. Especially if everyone else has run off to raid the Theil compound.

I think if i was this rich i wouldn't just build a bunker in the middle of nowhere but invest in existing town, help them become more independent/self sufficient.

Same for wherever i lived, the more people protected from a disaster the quicker they can rebuild.

I don't understand the desire to turn python into a high performance language. It's 2017, if you want performance just write some go/cpp/rust.

I think a lot of rich people underestimate the importance of law and order which allows them to benfit-from/wield their wealth. A bunch of guns, food packets or gold bars are unlikely to be of any use in case of a true catastrophe.
