The difference is in how the information got revealed (whether it was seen or heard is irrelevant). In the case where you saw the girl, it completely specifies the gender of the child you saw and unspecifies the gender of the unseen child. (Intuitively: suppose you know the family has four children, and you peek in the window and see that three of them are girls. What's the probability of the fourth being a girl? 1/2.)

The case where you are told the family has at least one girl is potentially different... It depends on how you get this information. If you ask the parent, "Do you have at least one girl?" and they say yes, then the probability of the other child being a girl is 1/3. On the other hand, if you ask the parent, "What can you tell me about your children?" and they say "I have at least one girl", then the probability of the other child being a girl is 1/2. The difference is that in the second case, the parent chooses which child to reveal information about, while in the first case, they are forced to make a combined statement about both children. In the second case, the parent completely reveals the gender of the chosen child while unspecifying the gender of the other, just as good as seeing the chosen child in the window.

Obviously, most people who describe the boy-girl problem are interested in describing the non-intuitive 1/3 result. But in their rush to reveal the "paradox", many state the problem poorly, leaving open the possibility of the 1/2 case (as Jeff did when he presented the problem).

(I added a similar response with more details in the Wikipedia article discussion several months ago:
http://en.wikipedia.org/w/index.php?title=Talk:Boy_or_Girl_p... I must warn, however, that the concluding paragraph there is incorrect: Jeff's problem is fundamentally undecidable as stated.)
The way you phrase it - "given that one of them is a girl" - the answer is 2/3.

The people who argue that it is not 2/3 and yet aren't confused are choosing a different interpretation of the problem. When your acquaintance tells you "one of my children is a girl", they interpret it not as pure information, so to speak, but as an event to condition on.

It's reasonable to suppose, for example, that your acquaintance could have said "one of my children is a girl" or "one of my children is a boy", and used the actual knowledge of his children's gender to pick one of the two possibilities to say (choosing randomly if it's a boy or a girl). In that case, the question becomes: given that he/she said "... a girl" rather than "... a boy", what is the probability that it's a girl and a boy?

In that case, the sample space becomes larger: to (b,b) etc. add also B or G, which is whether the acquaintance said "one of my children is a boy" or "... a girl". The possibilities are:

b,b,B: 1/4 (b,b,G is impossible)
g,g,G: 1/4 (g,g,B is impossible)
b,g,B: 1/8
b,g,G: 1/8
g,b,B: 1/8
g,b,G: 1/8

Now if you condition this sample space on the event "G", you rule out exactly half the possibilities, and the answer is 1/2.

The Kindle app can run in the emulator, right?

Nope. The iphone simulator doesn't emulate the ARM architecture, so even if you cracked the app store drm, you'd need to run it on an actual device. For something to run in the simulator, it would need to be compiled to i386.
From all accounts, Steve Jobs has much closer "creative control" of his product line than Bill Gates.

If you like Apple products (and nobody said one should), I don't think it is unreasonable to wonder whether you would still get what you want if Steve Jobs were to relinquish control of the company for whatever reason. The trouble is that because there is a major health issue involved, the whole speculation becomes a bit gruesome - not that the submitted article really raised the tone of the debate.

Your logic is correct but you are a making a different assumption, that Monty treats each door symmetrically. For example let's say Monty's strategy is to always open door #3 if he has a choice. Then if your choice is to switch to door #3 or to stay, you should choose "stay".

What if you put the scripts on Amazon EC2 (S3 or CloudFront), this will alleviate your server load and put it on Amazon's backbone.

My startup uses Amazon EC2 for hosting etc, and so far I've been very happy. We are not big either, actually we are a two-man team and definitely smaller than even you guys :) But Amazon seems affordable.

Just a thought, but no worries I think the service is still tremendous. Keep up the great job!
Yeah - track them down, sure, but then call the cops.

Otherwise the crooks will realise they can just use the iphone as bait to also grab your wallets and macbooks.
I found the easiest way was this:
You pick door A, the host opens door B or C and offers to let you switch to door C or B. He is effectively letting you choose between either A alone (by sticking) or B & C together (by switching) - i.e. by switching you open two doors instead of one, hence twice the probability.

OP's primary argument is well established: demographics.

Sure, the decline in demographics is well established, but why does that lead to a crash? A decline sure, neutral or negative growth maybe, but a crash? Crashes usually happen due to catastrophic events (wars, bubbles popping, oh look our finance sector is built on a house of cards). I don't quite see from that article why this is a crash and burn situation, especially in places like Australia who have ready immigration to boost demographic trends.

Yeah, downmod but, I'm performing a service so y'all know; better some anonymous person on the internet than someone to your face or, that you don't know altogether.
I've found that the most enlightening explanation is to increase the number of doors. What if the game is played with 100 doors, and the host opens 98 of them after you've chosen yours? At the start you only have a 1% chance of winning. Most people see right away that the host can't be increasing the odds to just 50% by opening so many doors. They don't always see the logic immediately, but at least they begin to question their intuition. Getting people to admit that they might be wrong is often the first step toward getting them to accept the correct answer. (That last sentence is a general observation that applies to a much wider range of problems.)

Again, I don't think he is addressing people who already have a job. Think about why he was even asked this question: apparently because there is this popular notion that America does not have enough IT workers and therefore needs to get 'em from India etc.

I am not sure how true or untrue that notion is. But it is widely accepted.

I do see your point and think it is valid: the current American compsci grads and engineers usually can find a job. What this guy should be talking about is EXPANDING the total size of the engineering/compsci grads so even folks not necessarily very inclined can come in and do tedious but decent paying jobs. The end result is more money goes to Americans and fewer importation of labor from India etc.
It's a bit late for that now. I don't see them recapturing their former (market) hotness any time soon. Although that's partially due to weak management, I think with the recession biting virtual worlds are too expensive an indulgence for many, not least in terms of time.

the least they can do is use that money to make an affordalbe electric car for people. Something with a $25K price tag.

It's not like it is impossible to do.

Tesla S is $50K...you can probably slash 5-10K by having them use a smaller base vehicle, instead of the Jaguar XF.

Smaller base vehicle means you need less batteries. The S weighs 4,000 lbs. so by using something the size of a Civic for the base vehicle, you can probably slash the weight down to 2,500 lbs. Which means you can probably get away with using 4,000 battery cells instead of 8,000. So if they pay $5 per battery cell that's another $20K saved.

Bam electric civic sized vehicle, for $25K.

I'm a little perplexed that you'd refer me to the dictionary definition rather than one from statute. This is the satutory definition of publication:

Publication is the distribution of copies or phonorecords of a work to the public by sale or other transfer of ownership, or by rental, lease, or lending. The offering to distribute copies or phonorecords to a group of persons for purposes of further distribution, public performance, or public display constitutes publication. A public performance or display of a work does not of itself constitute publication.

It was this definition I had in mind when questioning whether Nirmal's feed meets the legal threshold for publication. I'm not considering his work exempt under 'fair use' tests, but rather because Nirmal's involvement here is limited to disintermediating the gap between feed reader software and end content. The lack of monetarization by Nirmal has legal significance, as does the unavailability of the content in human-readable form on his website.

> So I claimed that HashFold can be more memory efficient than MapReduce. I make this claim because MapReduce needs to store all of the key-value pairs generated by the mapper, whereas HashFold only needs to store one key-value pair at any given time (in addition to the hash-table).

Not so fast. Yes, mapreduce stores all "unapplied" key-value pairs at the reducer. However, HashFold does as well, the big difference being that HashFold will start applying pairs as it sees them. While that's a win on associative functions, it's at best a tie on unassociative functions.
Nothing. It's commentary on my part on the the possibility of ironic unforeseen outcomes. Sorry, I didn't realize this might be misleading.

On the other hand, the times when this attitude actually pans out in terms of broken character encoding is vanishingly small. All it takes is one person with an accented name, or someone pasting in smart quotes to break your application and make you look like an amateur. The idea that Americans only need ASCII is silly.

He makes some very good points. Google's revolutionary (at the time) algorithm was all about increasing the relevance of results. It's a shame that the revolutionary thinking behind Facebook and social networking seems to encourage "spammy" type tactics. He mentions that it's more about creating content people want to share, but from my experience I'd say it's more tricking people into letting you use their wall, and message their friends.

My point is - would obesity & drug addictions be so widespread if people cared about their health in the first place? Babies are not born being obese and drug addicted (the vast majority). And if they don't care that much already, how can we expect them to care enough to put some effort into diagnosing themselves?
Can you go away and come back with an easier question?

Seriously, there are two cases here. First, the idea that developing countries (I believe the term "non-developed" is frowned upon) need certain skills to "compete" in the modern world. Now this is in some way a political or at least philosophical position, because it implies that all countries should seek growth. For example, you can imagine an island country with fertile soil where everybody makes an abundant living through agrictulture or fishing and have access to a reasonable standard of medical care. Do they need IT? Well I don't know. Depends who you ask.

The second case is: for the countries desiring to progress economically, is high-tech a good solution? I think there are some good examples (eg. India, South-East Asia) where the answer does seem to be yes. In particular the reason high-tech (of which IT is one part) is a good choice for a developing country is that it allows you to leapfrog certain historical stages thus eradicating your relative disadvantage faster.

The classic example of this is network infrastructure. The developed countries got network by literally having to dig the ground up and lay cables in order to wire up a city. Now if you were a city in a developing country that only now is getting around to be connected, you can go straight to wireless at a much lower total cost. So, the fact that you are so far behind becomes a comparative advantage - instead of being 20 years behind your developed counterpart you are suddenly only 2 years behind.

Of course the big issue now is energy. Suppose this afternoon someone announces a true renewable energy breakthrough - say a massively efficient but cheap to make solar cell. This kind of technology would allow a developing country to leapfrog centuries of expensive inefficient energy production (coal, oil etc) straight to the best solution. This is the great environmental fear right now - that populous countries like China and India will start laying down "dirty" energy infrastructures before the next best solution is invented.

Do you need high-tech more than hospitals? No. Does high tech help you decent hospitals faster? Many would argue yes.
Yea, these are the guys, good quality and price. I also like that they left the square backing on the circle stickers so they weren't impossible to peel off.

(Incomplete) Chicago's Venture Capital/Private Equity List
A recent thread bemoaned the fact that there are very few investment groups in Chicago that will fund startups. The link is a list from Crains showing some of the investment groups in Chicago, some of which DO fund early-stage companies.

I note that it is an incomplete list in the title, because I know of several funds that specialize in early-stage startups that are NOT on this list. Those funds tend to be a bit more publicity shy. This list might be a starting point for you, though,if you're currently looking for a funding source in Chicago.
