Okay, so doesn't what you said imply there could very well be a hidden variable that we're unaware of, that affects the two entangled photons as they are separated? What's ruling this out?
In football at the moment, there are two elements to price - wages and purchase price.

Clubs 'sell' players who are already contracted to them, to other clubs, in order to have the contract nullified. The price can be tens of millions of euro. The buying club will tie down the new player to a long contract as part of the purchase, perhaps 4 or 5 years.

Wages are low for young players, but will be increased rapidly if the player emerges as a real talent that other clubs would want, which gives the club the chance to extend the contract through renegotiation. A longer contract for a highly rated young player would mean higher wages also as part of the bargain, although contracts can be renegotiated and extended with higher wages at any time, if the club views the player as an asset that they wish to keep.

When they extend that contract it generally means that another club who tries to buy will have to pay more, and usually wages are at least matched and often increased by the buying club.

Sorry that's not a succinct answer.
It's incredibly random in football when it comes to assigning value to players, at least in Europe.

Take the example of James Rodríguez[1], a young Colombian player. His "value" suddenly skyrocketed[2] when he scored this wonder goal[3] in the 2014 World cup. Next thing, Real Madrid snapped him up for €80million, the decision at least partially influenced by Real's "Galaticos"[4] transfer policy, and the fact that Real can increase their commercial influence in a Spanish speaking country because Rodríguez is Colombian.

Other factors that influence a players value:

- time left on contract (longer time means more money)

- "marketability" e.g. player's ability to sell lots of club merchandise, and improve the club's brand

- perceived desperation of the buying/selling club (do they have a desperate need for a top class striker to make up for a lack of goals?)

- if there is a bidding war between clubs (e.g. young French striker Antony Martial was subject to a bidding war between Manchester United and Chelsea, dramatically driving up his value.)

- perceived transfer war chest of the buying club

- player's age

- if the player came off the back of a successful international tournament, which dramatically (sometimes artificially) showcases their skill. Sometimes teams will buy a player ahead of the tournament to prevent a later bidding war.

- skill of the player's agent (e.g. Raheem Sterling to Man City)

- then players skill and so on...

Every deal is a virtual once-off, it's always a bargain in hindsight[5] (whether you pay little or big money or not) and the player exceeds whatever the initial expectations were.

You can create user groups or G+ style circles on FB. For instance, I've got posts that only my friends see, most of them are also visible to my parents and very few are visible to acquaintances.

Add the representative of the bank to one of the limited visibility groups.

Not sure how that works when FB API is used.
Oh wow, did not expect this here! I am the current maintainer (not the original author) of cmus, and can answer some questions, if they'll come up.
I haven't the faintest idea.

In your example, cultural appropriation is bad when it happens to be racism at the same time. (Not to mention that making fun of someone can be asshole thing to do in it's own right.)

My two cents: I used cmus before, but in the long term I still prefer mplayer.

I construct the playlists myself by using soft-links to the actual paths of the songs. Real files are placed in sensibly named directories.

Hey Hanniabu, no filesize limit, it's fair use...
I haven't really maintained this software (as in doing on-going support) but I've added a few minor features like image and layout changes to an ancient VB 5 Windows application mostly by using a hex editor, changing the right assets and doing some rather interesting work-arounds in the underlying Access database.

It was both fun and scary. The software was a custom-built CRM / ERP system that must have cost a small fortune to develop. The company that developed the software has gone bankrupt quite some ago. I asked the former developers about the source code but they've simply lost it in all those years since 1997 or so when the application was originally developed.

So, here we have a company that's paid a large amount of money for a software - which admittedly is working quite well till this day - they now can't easily change anymore. Even something as simple as changing their postal address or adding additional branch offices takes considerable effort.

This should serve as a cautionary tale to always require some sort of source code access (preferably open source but some sort of escrow for the case the original creator goes under might work as well) to software that's pivotal to your business.
For the sake of your own sense of wonder, you might want to reflect on the possibility that what you just described a perception problem on your side.

However, I made an error back in 2000: my program ruled out all cases where A and B had a common factor, but actually, as long as C does not also share the factor, it is a valid counterexample.

Is there a proof for Norvig's less stringent "misinterpretation" that only A and B must share a prime factor? Or is it also unproved? What about C and just one of the others? Is it clear that all these cases are true or false together?

Less about wages, more about signing on/purchase fee. The analogy doesn't really work because in the non football world employees are not bought and sold in the same way.

There is occasional talk about doing away with the system, as it goes against a lot of employee rights principles.
Not a real question, but a sincere Thank You for the efforts. I believe maintainers should be praised more.
I think an important thing that we're currently missing is some kind of quantitative assessment what influence various measures have on software quality. All we have are "best practices" that all sound like common sense, but without much data backing them.

How much do formal methods really buy us it terms of quality? What's the defect rate if you use language X vs language Y? Is it better to spend lots of time gathering requirements and then produce something that exactly matches the requirements or is it better to iterate as quickly as possible and gather requirements as you go? What's the impact of the team as compared to the methodology?

I suspect the answers to these questions are really murky and its not clear whether there is a single methodology that produces the best quality for the money invested.
With young players, you take quantitative factors more into account than an older player. Staff and players at Manchester United have mentioned in interviews how Martial is extremely mature for a 19 year old, he is married with a child and obviously wants to provide for his family. The fact that he is French with limited English, means the tabloid horseshit rolls off his back and doesn't detract from his game.

I'm planning to do something like this workflow most probably reinventing the wheel along software history:
- Every release is already tagged, and merged into master (git-flow).
- There is a post-commit hook to backup the database with the tag and time. So I know which database tag is newer.
- Store the encrypted zip on S3, since each developer can deploy.
- Deploy, like cuu508 did.

The problem is with restore. If there is no change in database it is more or less straight forward to download and import the db with the n-1 code tag. But if there are any inserts in database then a migration back should be applied to the latest stand of the database. I can imagine it's going to be a hefty workflow to do.

My laser pen seems to disagree...
So, then is it correct to say that an outside observer can never tell if a particle he/she is looking at is actually entangled? This outside observer would simply observe that the particle has spin "up" or "down" but would never know that it was entangled earlier by someone else. This observer would never know it was in a superposition unless they had knowledge that someone had previously done this. Only the person who entangled the particle can clue the observer in on the fact that they were entangled.

I can give you a particle, tell you it's in a superposition but you'd have no way to verify this. If you observe the particle, perhaps you'd see it's in spin "up" but that would be meaningless because that observation wouldn't tell you anything about whether it was entangled or not. You only know about its current state. There is nothing in your observation that shows "hey the particle just changed from superposition to spin up"

Thanks for the replies! I watch "word science festival" and similar videos and I am fascinated by the quantum world but I have wondered these questions for a while and didn't know anyone who could answer them.

I saw this great Veritasium video about measuring quantum particles but it still left me with the questions above https://www.youtube.com/watch?v=ZuvK-od647c
A referentially transparent, small function, has always been easy to write bug-free assuming the OS doesn't lose a page-table entry, a network interrupt isn't exploitable, and cosmic rays don't flip bits. The issue has never been that we can't write something that's correct.

Getting that correctness to propagate because of the strictness of all the tools involved and accuracy of their construction is the issue, which leaves us with needing to either automate proofs with Coq or prove things in more general ways that lead to undecidable problems etc. Still, the fact that one function can be written bug-free and known to be bug-free does indicate that it's not an inevitability of probability playing out as code grows.

We have null-pointer exceptions and no maybe type. The API's that emit nulls sometimes make me expect sewage to leak from light sockets. It's possible to do better. We just don't, and none of us love it. Rust and Kotlin are at least very exciting. I'd like to understand some Coq more in the context of x86. What routines are strictly necessary to even do Coq? A response based on some statement about how the Y-combinator enables X where X leads to Y would not surprise me.

The trouble with time travel
First, the bank might not care whether it's really you. If there is someone with "bad behavior signs" who is sufficiently similar to you the prudent thing to do if you want to minimize loan risk is to assume that it's you. Secondly, it's really simple to deanonymize data. Check for example

http://33bits.org/2011/03/09/link-prediction-by-de-anonymiza...

As the site name implies, you need just 33 bits of good information to distinguish every person on Earth. It's not hard to get enough bits from your Facebook timeline to cross-correlate it with other stuff the bank might know about you.

Virtual Reality Basics
I started working in financial tech in 97, and I've seen a number of "one model to rule them all" efforts come and go since. Back in the late 90s I saw consultants touting Java coded UML models as the way for banks to build the definitive object model of their trading operations. In the early 2000s I worked on JP Morgan's Kapital, an early 90s Smalltalk risk management system using the Gemstone DB. That was supposed to be the last word in derivatives abstraction. And more recently I spent some time working on JP's Athena project, a Python NoSQL system with an implicitly functional graph programming system that enables Python code to behave like spreadsheets. I suspect the ability of traders to invent products, and more recently regulators to invent rules, will always outstrip the ability of coders to invent clean abstractions that will factor the financial domain neatly.

A new photon is emitted after absorption by the old one, the new one is absolutely indistinguishable from the original.

Yes, but the fact that a company manufactures pharmaceuticals that are known to be dangerous but used in a controlled way (e.g. narcotic substances used for sedating persons when making operations by qualified medical personnel) is perceived by the public highly differently from manufacturing and delivering the same narcotics for recreational use.

And I think this is quite understandable, and not really about "war on drugs", it's about corporate responsibility.

Many companies are taking some flak for supplying completely legal chemical substances to the public (say, sugar drinks).

The following contradiction is pasted from the British actuarial notes: (hopefully within the terms of fair use)

"Overconfidence

People tend to overestimate their own abilities, knowledge and skills. For example, if you ask 100 people if they are better than average drivers, then you might not be surprised if more than 50% of them reply “yes”!

Moreover, studies show that the discrepancy between accuracy and overconfidence increases (in all but the simplest tasks) as the respondent is more knowledgeable! (Accuracy increases to a modest degree but confidence increases to a much larger degree. ) If this is true then it may not be wise to pass the Subject ST5 exam!

Overconfidence could therefore be a potentially serious problem in fields such as investment where most of the participants are likely to be highly knowledgeable.

Moreover, the available evidence suggests that even when people are aware that they are overconfident they remain so."

The music is the one liner, the rest is just a lowpass filter (IIRC it's run at 48khz here), and stereo noise for other testing reasons... IIRC this kind of glitch music was substantially better at exercising the code than other similarly simple test stimulus (pure noise, or simple tones).

>"that wouldn't make it magically correct"

It wouldn't make it standard, but I argue that if the person you mean to receive the message recieves it using that combination of letters, what's considered "correct" by x number of people is irrelevant.

Hence "correcting" someone when you knew what they meant is absurd.
The reason we know the photons are indistinguishable is because quantum mechanics deals with configurations of particles at locations, and these configurations predict different outcomes depending on whether "photon A here and photon B there" is a different configuration than "photon B here and photon A there". If A and B are distinguishable, the configurations aren't the same, and you'll notice real quick when your experimental results don't line up with expectations based on them being the same. Mathematically it's as simple as the fact that x^2 + y^2 != (x+y)^2 for all x,y.
