Soap bubbles appear colourful in the sun in spite of low coherence because the soap film is thin. Soap films can be as thin as tens of nanometers meaning that light has to be only coherent for a femtosecond for interference to happen -- and this is very comparable to the cycle time of the light itself so that coherence is practically assured. But the round trip time in a 5mm window pane is 50 picoseconds, which is thousands of times larger making coherence important.

The rules around who gets copyright and royalties is a bit abitrary in many fields, so I have some sympathy, on the other hand I like the quote from famous session guitarist Tommy Tedesco on this topic (can't locate the quote so paraphrasing from memory):

Yes. And I fully agree that without the demand there would not have been the supply. I’m not trying to start a “butwhatabout” here.
Well it's fairly simple - we have a building that only has office people in (not many, but some)

The cost of that building divided by the number of people there.

There's then power, heat, cleaning, etc, but that's all small fry compared with the rent or opportunity cost of an office building.

The technical infrastructure (Cisco switches don't come cheap) is probably offset by the cost of supporting remote infrastructure, vpns etc.

The cost per deal in central London is on the order of $10k-$20k a year. I'll take that in cash thanks.

I did not start to learn programming until I was 35. My college major was journalism. But, in 1997, I was able to get into a entry-level programming job while I took college courses in computer science. Now, 20 years later, I am a successful software engineer. If you are hungry, it's never too late. And I will ask you to notice that I did not start in this business until I was of an age that most people think is over the hill in this business. Get into programming, study like your life depended on it and you will succeed.
It was a technical project with the goal of proxifying your stuff via the onion network. They made it about human rights. Accessing forbidden websites is just one of all the things you could ever use Tor for. You could also use it to buy drugs or hire a hitman or troll online or watch child pornography. Why not call it a "hitmen for everybody" project?

This is such an odd story.

The guy sold a painting knowing it was going to be used by a rock band for an album and took a one time payment.

Then he spends the next several decades complaining about it, so much so that his son tries to extract some sort of narrative about the whole process to support his fathers position.

In some ways I can actually relate, so perhaps I’m projecting my own hurt from lack of Justice... but in this case the guy was paid and it was only after it was successful did he start wishing he got more money.

>If you're not from the US what country are you from that would have a benefit from eliminating net neutrality? What are your reasons for not supporting it?

I am from a country in the EU. I don't support NN because I want to have access to zero-rated services. As a consumer, they make my life easier and my bill lower. I want to have the freedom of choosing whether I want NN in my connection or not. I don't want the government to take that freedom away from me.

>Are you saying the only companies that can take a stance are ISPs? And they can lobby governments but an independent company cannot?

They surely can. I was just surprised because Mozilla pride themselves so much in diversity and the common good. I suppose their diversity does not include diversity of thought.

Alternatively, we were already hard on drug addicts and it was reflection of the time. Fast-forward to present day, we've been steadily shifting towards a more reasonable approach towards drugs, slowly but surely.

It's also well established that the black community was for the harsh laws of the crack epidemic, having believed it would help end the crisis by keeping criminals off the streets. In that light, the results start to look more as a result of unintended consequences than some type of modern-day chattel system as implied by present-day activists.
Countless cities and towns where there is only one ISP, or a duopoly in cahoots to keep prices high and service low, and freezing competitors such as Google Fiber out of the market.

This isn't exactly new information, if you haven't noticed the problem by now, you must have been living under a rock.

There are hundreds of credible reports and articles about this problem.
Because regulations that “prevent” bad actors actually have unintended consequences that the big-government people never seem to grasp. And free markets are far more powerful and adapt far more quickly than regulation — while preserving freedom for people to make their own choices.

Certain European governments in the past century made regulations to “protect” society — and that resulted in millions of people killed or displaced. China’s Firewall is design to protect society against “bad actors,” and it instead suppresses the free speech of an entire nation.

“Bad Actors” to you are innovators, hackers and freedoms fighters to someone else.

Trust in government is the stupidest thing a society can ever do. We need governments for sure, but it should be a government with extensive limits to their power and it should be viewed with an attitude of suspicion. But, it seems like people instead are relying upon government to be replacements for parents instead.
As a customer, NN does not benefit me. The opposite. I will lose access to zero-rated services if it's implemented. I don't want that to happen because then I will have to pay more money for the same service.
Yea, it's much easier to enter a matrix on a modern Casio than the HP calcs and requires fewer keystrokes I believe. I guess navigation of the indices takes up time on the Casio, but it is so intuitive.
Both incidents kill many people. Hydro plant failures in short term - Nuclear plant failures in long term. Both is bad.
But additionally nuclear plant failures also make the affected environment for a long time unusable. And I'd say harm more people because of the long term effects.
I love it when people doing bad things get busted by statistical traces they didn't even realize they were leaving. There is a lot more room for this kind of detective work.

No, he didn’t. The assembly line existed before Ford applied it to cars.
In that table, "Fossil steam" is 42.2% more expensive to operate than nuclear[1], that's pretty significant.

In jurisdictions that have already joined the carbon trading traties, there's an additional big operating cost in the emission credits that would make the coal position significantly worse still. USA and other lagging countries will have to join too soon or we'll all pay a vastly higher price in the form of deterioration of living conditions.

[1] "Total" value for the most recent available year is 25.36 for nuclear, 36.08 for fossil steam

Oh, didn't even notice that (as I don't follow (American) politics that closely). Seems even more unlikely that this had anything to do with the elections then.
I find your grandmothers advice simplistic and somewhat unhelpful.

In particular, it makes it sound like there’s a simple algorithm you can follow to solve problems with children crying.

Unfortunately, sometimes children do cry for hours and it’s tough to figure out why. Suggesting that they don’t gives people without children an unrealistic impression of parenthood.

Is this not taught in school in the US? My country (Spain) profited by the slave trade as well, and the general process of how slaves were brought to our colonies was taught. The man of the article was from (or close?) Dahomey, whose Kings became fabulously rich by selling slaves to the westerners [1]:

King Tegbesu made £250,000 a year selling people into slavery in 1750. King Gezo said in the 1840's he would do anything the British wanted him to do apart from giving up slave trade:

"The slave trade is the ruling principle of my people. It is the source and the glory of their wealth…the mother lulls the child to sleep with notes of triumph over an enemy reduced to slavery…"

Other African Kings were making bank as well. After the British made slave trade illegal in 1807, a distraught King of Bonny complained [1]:

"We think this trade must go on. That is the verdict of our oracle and the priests. They say that your country, however great, can never stop a trade ordained by God himself."

You can still get interference if the medium is thicker than a wavelength, but it needs to be close. This effect is quite often seen in CCD detectors used in infrared spectroscopy, as well as certain detectors used for visible spectroscopy. It's called etaloning. But as you suggest, in thicker media there's much less chance of it happening.

That's fascinating and good info.

I'm a little biased. We got a lot of information pushing us not to supplement from health professionals and organizations, and nothing on the risks of failure to thrive or the case for supplementation. We had a calorie deficit no one caught, because measuring breast milk consumption is opaque, and no one talks about low consumption with the same fervor. They should though, it's an issue that drove an entire industry of wet nurses before formula (who were in turn criticised as unnatural in their day). They say breast if possible, but never detail how to tell the difference between just doing the hard work, or just banging your head against an immovable wall.

This inconsistency in advice, even though calorie deficits are incredibly dangerous, and more clearly so,[0] worries me there's a bias against technological development that keeps us from giving advice about both risks (or really much at all about the more important risk here).

[0] insofar as there are conflicting metaanalyses on breastmilk, but the signal is far stronger here, no one is publishing research suggesting failure to thrive is no big deal.

I don't understand this. Can someone explain to me the argument of "ISPs in the US are monopolies, so more regulation is worse for the customer"?

If your ISP is a monopoly, they can do whatever they want if left unregulated. They can literally charge you whatever they want.

Zero-rated services are zero-rated because you pay for them indirectly. I guess losing access to them would be a downside, and would prevent Facebook from becoming even more entrenched, which they certainly don't want. It doesn't do anything for internet freedom, though. You might as well say "well the internet to me is Facebook, so I don't care if the internet is free, I just want it to run Facebook".
I mean, I haven't crunched the numbers, but unless wind/solar are legitimately the most cost effective options (which historically they most certainly have not been) then you would have to be a real risk taker to get involved.

Really?

The 2017 Lazard report (which I think is generally pretty well regarded) has them at:

Coal, min: 60, max: 143

Wind, min: 30, max: 60

https://en.wikipedia.org/wiki/Cost_of_electricity_by_source#...

There are plenty of other sources on that page. You'll quickly find that most show wind power being cheaper than coal since around 2012 (even without a carbon price).
Hey Andy — love this. But really you are developing a framework for figuring out how much time to invest in research.

A couple of questions — which was prompted by your blog

What situations is there no value in research ?
Corrollary — are there ways you can systemically reduce your risk by increasing your gut feel for probabilities without reesearch ?
Final one — you make the great point on unknown unknowns — apart from systemically working through all possible states and thinking through various envrionmental changes — are there any systemic approaches to reducing this risk.
In working with startups — I would summarise an alternative approach that covers all 3 by the following pieces of accepted wisdom from startups.

Launch early — to validate in the market with real people
Talk to customers to build an empathy or gut feel for relative priorities of stuff — and what really matters
I think these two principles go some way to solving the problems you are highlighting through a different approach.

I’m sharing — as I’m sure you have considered this appraoch — and have a reason for discarding it.

You're right about people being irrational.

If you're worried about someone else getting rich from your work, while you get nothing, but it's impracticable to get royalties because the work will be used to create various derived works in various unforseeable ways, then perhaps the thing to do is offer them, in return for an immediate cash payment, non-exclusive rights for ever, but exclusive rights only for the first five years. You'd probably have to put something in about the purchaser licensing back to you any other necessary rights (e.g. trademarks) to make this work, but it might then mean you'd get a second chance at negotiating five years later. In the case of the cover of a successful record, either they come back to you five years later with more cash, or else you sell your remaining rights to someone else who wants to make T-shirts or whatever. Or you donate the image to the public domain if that's what you prefer. I'm suggesting this approach not so much as a business plan but as a way of avoiding irrational feelings of frustration or indignation, but it might also be a good business plan in some cases.

Personally I like non-exclusive rights. It helps avoid orphaning of works and ridiculous situations in which it's impossible to republish a book unless you can get 19 people to all agree and give permission because that's how many people might have inherited a share in some required exclusive right.

Parenthood, particularly in some communities is like entering some kind of twilight zone.

In particular I’ve been shocked at how many fathers do almost nothing in terms of childcare. It’s a shame that there isn’t a more general expectation on fathers to look after their kids at least to some extent, and that not looking after your kids isn’t considered socially unacceptable.

I don’t believe this is just the fault of “men”, but I think it comes from a surprising lack on understanding in terms of how much work looking after kids is. It’s pretty much a 16 hour a day job for the first few years. If you don’t have someone to help it’s almost unbearable.
I live in the first world so I have many many choices to get a wired or 4G connection. The government forces ISPs to share their infrastructure. I understand that kind of stuff does not apply to countries like the US, but I'm talking about my own case here.
Ah I see your point. I guess a similar thing happens when you look at plastic with polarized sunglasses, then you see different colors (though there's a chemical issue with plastic as well that affects the polarization of light)

You could do a 5mm(+/-10nm) glass pane for it to reflect/absorb a specific wavelength but it would be hard.
They had this for a while and it was even more partisan, though I believe the main effect was emigrants voting for their home country (Britain voting for Ireland, Germany voting for Turkey etc).

No, this is a disease like few others. When a mother and father's blood type only varies by the positive or negative part there's a chance that from the second pregnancy onwards the mother can react to the fetus's blood.

Compare that to the cold, a virus; mad cow diseaase, a prion; strap throat/etc, a bacteria, huntingdon's disease, a genetic flaw. Nothing could work on all of them. CRISPR shows that some solutions are only a method to a personalised treatment.
Dude, I left working as a doctor this year (32yo) to be a programmer/web developer. Based on what you say about your current job you really have nothing to lose.

Please note that I learned programming etc. for many years while studying medicine and working as a doctor. I'm not suggesting you to dump your job just yet.
(Warning: I have zero expertise on this)

Apparently there's an argument about that, since there's a plan to upgrade the Snowy Hydro pumped storage system, but it'll cost $2B and it couldn't be done in 100 days like the Tesla installation. The other advantage seems to be that the battery can respond very quickly (0.14s), so it's still useful to avoid instability in the network.
You have to also understand that many neighbors hate each other far far more than a distant enemies regardless of evilness scale. Iran vs Saudi Arabia, China vs Japan, S Korea vs N Korea, India vs Pakistan, Scotland vs England, Alabama vs New York :). Many people in these groups will happily sale people on other side as slave to green aliens in exchange for wealth and dominance.

After you understand this, its not hard to imagine that white slave traders would naturally leverage African tribes at constant wars with each other to capture other party's members for money. What's better than killing your enemy? Make them disappear permanently while becoming rich and powerful!

I also doubt if African tribes actually understood this as part of war against their own race. The white salve traders would have surely treated their helpers very nicely and respectfully while introducing themselves as service providers to take their enemies away in exchange of money. People in Africa would at that time have little means to know what these white slave owners in Western world really thought about them and how they treated them because of their skin color.

So the slave traders systematically exploited same trick that colonials used to dominate vast populations with extremely small number of their own people: identify factions, take sides, wait till one faction gets weakened in economic and military strength from wars, load them up with debts and fear, and finally submit them to obedience. The classic divide and conquer strategy works every time through out the history in all kind of different problems.
There are also a couple of recordings of people who were born into slavery and were then freed.

This one in particular still sends shivers down my spine whenever I listen to it:

In this particular example, I don't see why. Player and Warrior are conceptually different entities: one is the player of the game, having properties and methods related to controlling gameplay (e.g. a player might play as alternate warriors at different times), the latter is the avatar, having properties and methods related to that fictional characters attributes within the world of the game.

The differences in purpose of the two entities aren't really anything to do with fp vs oop; I don't see what's fp-ish about the first example, and your last example is potentially a weird mix of fp and oop (depending on what "warrior" is, and I can't figure out what use it would be in that context if it wasn't an object with encapsulated methods)
If I pirate your software, or use your patents,trademarks, copyrights then the companies,startups will appeal to government to put me in place instead of appealing to free market.

So maybe some rules,laws are needed, just that the ones you do not agree are bad and the ones you agree with are essential.

Didn't you hear in school a story where some guys went to live in a forest and they agreed to have no rules, then some started to do some bad things and they started added a few rules, then more rules because there were needed to prevent bad things, in the end they got similar rules as in the place where they started.
Interesting. I'd be curious to know if the author has read "The Influential Mind" by Tali Sharot. Long to short, humans are wired to be anything but rational and purely logical (even when necessary).
