The host knows where the car is and so leaves it hidden. If some one shows you this with even just 10 doors, it will be immediately and patently obvious that you must switch.

Like everyone who encountered this in their intro stats class, I love this problem. And it bothers everyone the first time.

Are there other problems like the Monty Hall problem, perhaps in other disciplines?
> What is the threat posed by, say, Germany?

Well they're one of the world's major industrial powers and just a couple of generations ago they threatened to take over all of Europe.

So much of the outrage over NSA spying (abroad) is predicated on this foolish idea that we live in a time outside of history, that while the West may have spent the better part of the last millennium embroiled in warfare with each other, that our generation is the first to be so enlightened as to make that unthinkable.

> Google "collective action problem" and "free rider problem."

You mean, like expecting everyone to research politicians and political issues and vote responsibly?

A government (or, at least a democratic/republican government) is also a public good, and is at least as susceptible to those problems as government roles like welfare and public defense.
unless your goal is to get the public behind the NSA in order to hang Snowden one way or the other

My opinion is that this is exactly it. Once Snowden is here, the "amnesty" will end just as soon as they can hang a false statements charge on him, then parade him in handcuffs or on trial to discredit everything associated with him, including Greenwald et al stories, after which they can continue their business as usual. Make no mistake that Clapper, Alexander and Holder would LOVE to make a Rosenberg out of him.

Wait, so people think "IT" means desktop support? Network architect is IT. Sysadmins, network admins, "devops" (remember when they were called sysadmins?) are all IT.
I do the same thing by expanding it out to more doors, but when talking about it or explaining it to others (great cocktail party discussion btw), I use 100 doors, to make the percentages easy to follow.

Example - there are 100 doors, you pick 1 that has the grand prize. There's a 1% chance you picked the prize on your selection. Monty Hall eliminates 98 of the doors, meaning there are 2 left. There's STILL a 1% chance you picked the door with the prize, but that means there's a 99% chance the only remaining door has the prize. Obviously, you should switch.
If you dislike buzzwords, don't use them. Calling IFTTT "cloud-based" adds nothing over calling it "online" or "a web site". It might use the cloud, or it might know exactly where its servers are, but that isn't important here.
The problem is that menial work (arranging meetings, organizing schedules, handling communications with colleagues and clients by phone and mail) used to be handled by secretaries. If Mad Men is to be believed, at a certain employment level you would get a personal secretary and below that you could draw from a common pool. Where did all these secretarial jobs go? Their title was changed to "manager" and they were put in charge. God help us all.
It's not a "skill" per se, but demonstrating you will reliably show up on time and do your job has a definite value in the labor market, and could lead to other opportunities.

Your tone suggests that you think I don't understand what you're saying (which perhaps I wouldn't, since you succeeded only in telling me I was wrong and failed to actually explain "how modern persistent data structures are implemented" -- as if they were all implemented the same way). Your last sentence suggests that you don't think I know that efficient immutable data structures are an active area of computer science research. Both assumptions are incorrect.

Now, I realize that in my original post, I might have given the wrong impression. I thought that by my second post I was being clear enough, but perhaps I wasn't. Let's try take three:

Immutable data structures do not necessarily guarantee less copying, or necessarily imply a performance gain. A data structure which does not lend itself well to immutability, such as a C-style array, can lead to very inefficient code when used in an immutable fashion. The C-style array or a variation thereof is also the default in most current languages, including Java, Python, C++, Ruby, and many others, so this is hardly a thing of the past. It's important to be aware of the performance characteristics of the data structures one is using, respective to the way in which they are used.
Being a critic is far more difficult than being a complacent tinkerer. Criticism requires analysis and pushes you into conflicts. Tinkering can be done inside of a cozy turtle-shell. Anyone who creates something fundamentally new has to be a critic to a some extent - doing new things is essentially criticizing the current state of reality.
The Lost Art of the Soft Launch
#3 Mike Markkula was the money man
Markkula was an early Intel employee and became a millionaire by the time he was thirty when the company went public. According to "Return to the Little Kingdom," his investment in Apple was less than 10% of his total worth at the time.
He stayed at Apple until 1997, overseeing the ouster and return of Steve Jobs. When Jobs came back, Markkula was left. He has since invested in a few startups and donated money to Santa Clara University, for the Markkula Center for Applied Ethics.

#2 Steve Jobs was given the number two just to irk him
Why is Jobs employee number two? Michael Scott says, "I know I didn't give it to Jobs because I thought that would be too much."

#1 Steve Wozniak was the technical expert
In the book "Return to the Little Kingdom" it says Wozniak told his parents with "steadfast assurance that Apple's bigtime investor would lose every penny," which indicated to use he lacked faith in Apple's success.
Because you can't be passionate about B2B apps. When we're reading about that to become an entrepreneur you can't be after the money, you have to do something you're passionate about, something you would die for.

All this, passion, solving a problem to die for, disappears by doing B2B and you're only going for the money again.

Of course there are exceptions, but that's the difference between B2B and B2C.

Right there with you on the keyboard shopping; it's an expensive potential mistake to make.

I'm reading a very helpful book (It's Not Carpal Tunnel Syndrome) that is showing me the root causes of my RSIs, and the keyboard is only part of what for me is a pretty ugly picture that's developed over several years. If you go to the author's blog - rsirescue.blogspot.com - and look on that page for "Our Theory in a Nutshell" you can get a quick overview and see what I mean.

I realize reading a book won't provide an immediate solution for your problem, but since I've been trying to sort through the keyboard issue myself and only stumbled across the book (which has so far been extremely helpful) I felt I should mention it. The book helped me realize a better keyboard will address some of my symptoms but not all of them and not all of my problem.

If you've just started having RSI symptoms maybe the right keyboard would provide some quick relief and you can use the "Not Carpal Tunnel" information to keep it all in check. I have spent too much time and money chasing after solutions I hoped would be a silver bullet, only to find that they were either harmful or only partially helpful. RSI relief is turning out to be a puzzle with many pieces.

All that being said, I stumbled across this page because I searched for the same thing you were looking for. The authors of the book provided a resource list that included a link to a site that did rentals. Now it's just a linkfarm :( I found a couple of other results that led to sites with rental programs, but they were only local. Would love to find a rental but if that doesn't happen within the next few days I'll pick one and buy where there's a good return policy.
It's far from proven that wearing a cycling helmet has a net benefit from a safety view point. Helmets are useless above 13mph and not a lot of good at low speeds. What's more, they may cause accidents as they can restrict vision, or make riders slightly less responsible as they "feel" safer and consequently take more risks. Rule number 1 for a cyclist is: don't have an accident. I suspect helmet wearers have more accidents. I speak from experience having been hit by a cyclist who didn't see me because his helmet restricted his vision.
I don't see why the author thinks we would ground our fleet. Police routinely and deliberately kill innocent people in the US, and we don't "ground our police force."
That's a bizarre definition of "take advantage."
Really simple way to buy lottery tickets. Have been using it myself! Good job.
I guess you are lucky. I had a fall which could had taken me to ER. It happened when I was relatively new to road bike and tried to enter a drive way like a car. Wheel of my bike trammed along the road and sidewalk (about 2 inches high). I lost balance, took a fall on concrete sidewalk. Right side of my helmet took the hit. The impact was severe enough, it was dark (not pitch dark) in front of my eyes for next few seconds. However, I was able to bike back after 15 mins of rest. I can't imagine doing that without the helmet.
That's even faster than the push-pop sequence that this describes.

Well - have you worked on enterprise software? It's not fun.
Three words: JOIN, JOIN, JOIN. For any non-trivial domain, you'll need to join different entity types. For example, a collection of users is fine for user names, (hashed) passwords, last logins, etc. A collection of document is fine for text, fonts, URL. Now what happens if you have multiple users collaborating on multiple documents? Are you going to denormalize the shared documents to user objects, or are you only keeping document IDs in them? If you choose the former, you'll run into inconsistency very quickly. If you choose the latter, you'll need join support, or you have to write the code to do the poor man's join which could be very inefficient.

RethinkDB supports join out of the box.
It was the sales cycle that killed my company off (many years ago).

When three or four deals, with a 6 month lead time turned into an 18 month lead time, as things got pushed into next year, it meant we simply ran out of cash.

And with such a long and intensive sales cycle, we couldn't afford to have a large number of fallback leads at the same time.
As per https://news.ycombinator.com/item?id=6911908, you should check and double check that you are not exposing any secret keys or credentials.
lol - yeah, I have the same problem. I recently did some pairing on someone else's computer and it took me a good 20 minutes to start reaching for the intended key instead.
I have the same problem some days. I think we're addicted to the thrill of reading something unusually interesting or that happens to give us information pertinent to our current needs. But as you say, that seems to happen less now, so we're like gamblers thinking that if we just stick with it our luck will turn.
And therein lies the rub -- I don't mind being addicted to nicotine any more than I mind being addicted to caffeine. To my current knowledge, they both seem relatively harmless, aside from the addiction, until and unless one tries to quit them, which causes withdrawals, and the cost is effectively negligible.

The main reason for quitting smoking had less to do with health concerns than cost, and not because the costs were unbearable, so much as that those costs were ridiculous. Ecigs have changed the equation, and so long as my nicotine budget stays lower than my caffeine budget, it's effectively negligible, however ignorant it might be.

As for the rest, you're completely right. It is a psychological problem. I'd need to see a good reason for quitting nicotine before my head can agree that there is one. I was worried about the costs rising, but they seem to be going the other way. I was worried about the health risks of nicotine, but indicators seem to be trending towards 'ecigs' are safe... and while I'm aware that the science could be wrong, incomplete, or even manipulated, I've gone from 'trying to quit' to 'meh, it's a harmless vice' mentally.
>> Everyone's family wants a rich dad/husband/brother/wife/sister/mom

Just to echo some of the other comments above, this is absolutely BS. How many kids, when they grow up, say "I wish dad worked overtime so we could be rich". Compare those kids to those who say "I wish my dad was around more, but he was always working".

To think your children will be disappointed when they're not rich...well, you're living in a self-inflated bubble. I hope you come out of it.

Best explanation I've seen was using statistics: simulate the problem 1000 times. Look at results when you switch and when you don't switch doors.
Or do it in your head: If I switch doors, I will win with 2 out of 3 doors. Otherwise, I'll win only with one door.

Education has that potential, but it also has the potential to indoctrinate and pacify. I agree that innovations in education are exciting and valuable.
The challenge with all these things is to make sure that the evidence hasn't been faked. That's why we end up asking people to do some simple tasks in house, before then even considering proper pairing sessions on real work. We had a candidate who actually surreptitiously did a "phone a friend" wile allegedly producing some trivial code to do something FizzBuzz-like.
Congrats to the the Crowdtilt team!
Of course there are "other chemicals" in them. Everything is a "chemical", and it's obviously unsafe to work with and vaporize pure nicotine.
So you're dismissing a project because you drew an association between it and a boogieman caricature of people that you (perhaps even rightly so) don't like? OK, be my guest, but keep in mind that's a dangerous road to head down.

I like the simulation at the bottom. Sometimes it's best to just say, "The math gets confusing, let's run this a couple times and see what happens."
In the enterprise market you have to talk to 15 different people inside a company before you can make a sale. And often you have to go out of your way to convince them trying to cover every little insecurity they have and learn to live with the anxiety of failing because of actors outside your influence. You also have to dine them and wine them and laugh with their stupid jokes and generally try to be as pleasing and understanding as possible. The hell with that. In the consumer market things are a bit more straightforward. You focus your energies on the product and marketing and that’s all there is.
The funny thing is that this has been done before, but as there is not enough evidence to try them, they are locked up in Guantanamo indefinitely.

I guess drone strikes are just a cheaper solution for that problem, with less outrage than prison camps.
Oh, I was just reading an article about this (http://www.hackreactor.com/blog/Building-a-RethinkDB-Module-...) and I'm sad to hear it's currently broken. I really hope the meteor guys add support for something better than Mongo. I've already ran into scaling issues on a meteor app I use to gather analytic information. You really need to implement sharding very early on with MongoDB in order to keep memory use and locking issues under control. To me that means a large investment in hardware and infrastructure just for a personal project.
The best explanation I've seen was in series 3, episode 3 of Jame May's Man Lab, where they repeatedly iterated the problem and showed that when repeated enough times, the frequency of winning/losing tends to a different value with a change of door than without (by having the presenters open booby-trapped beer cans and either get splashed with beer or not)

They also include this in their Terms of Service[1] -

"All claims arising out of or relating to these terms or the Services will be litigated exclusively in the federal or state courts of Santa Clara County, California, USA, and you and Google consent to personal jurisdiction in those courts.

This particular clause has been upheld several times for Google.
