But what is not obvious is that the VC might not care if _your_ company is the one that makes him money. Remember that VCs are managing a portfolio of companies, in order to spread their risk. The VC might decide that your company is in the part of their portfolio that won't go big, and so they won't give it any more but the bare minimum of attention.
The poster was clearly not discriminating. Reading this from a female perspective he was just telling facts, and I don't see this as HR's problem either. We women need to learn to negotiate, and learn how to do this while maintaining the need for social inclusion. There are still a lot more men in the tech business which does affect the manner in which you discuss money and it's hard even for me to negotiate (and I've been in business for years). It's a matter of telling your social-brain to shut up and put your personal-survival-brain first, maybe.

I don't see this as a gender issue so much as a personality-type issue, it's secondary that many women happen to have the personality-type where social concerns come first. When clients ask me for a discount we'll almost always give it, but I'll be much happier to work with a client who approaches the matter in a sociable way rather than a direct request for a discount (I find it tasteless, even though the money-brain side of me completely understands what is happening).

Just a side note: I have male employees who also suck at asking for raises.
You can follow a similar process to work out the probability as for the original question. For any two children, the possibilities are:

Child 1 born Mon, Tue, Wed, Thu, Fri, Sat, Sun

Child 2 born Mon, Tue, Wed, Thu, Fri, Sat, Sun

We know that one of the children was born on a Tuesday, but we haven't said whether it's Child 1 or Child 2 (and that lack of information is key to understanding the original problem), so our unknown child could also be either Child 1 or Child 2.

With that in mind, 'unknown child' has 14 possible options except that we know one of those options (our known Tuesday child) is already taken - we don't know whether it's Child 1 or Child 2 but that doesn't matter, we just know that one of them is already taken. That leaves 13 possibilities for unknown child, only one of which is 'born on Tuesday' (since we've removed the other 'born on Tuesday' option), so I would say the answer is 1/13.
It's a razor model. The handle is free, but you pay for the blades. In this case, the blades are the (non-standard width, thermal) paper.

Meanwhile it doesn't give the user anything useful that they can't already read on their smartphone, does it? So what is it for? It's not a substitute for the existing multifunction printer. It's an inferior substitute to the existing RSS reader or equivalent. There's no value proposition I can see for the consumer, so they must be looking at some other source of income, which means there must be some value proposition for the information suppliers. But what is it?
It comes from the short term view pretty much all companies have these days. They underpay, have nice looking budgets, manager gets promoted. The churn costs the company but the person who caused the problem has already moved on.
Thanks! It was the destructuring part that I wasn't understanding right away.

I think it's a little depressing that they paint a picture where people no longer roll out the newspaper in the morning, but instead print a miniscule dashboard of social media updates to be digested along with the eggs and bangers instead.

I wonder how true the replacement with the "social media breakfast" is, though.
nah, that's just consensus building - another trait of the female of the species. I've seen it plenty of times before: it takes me 10 minutes to make a decision, and I call no one. It takes my wife two days, as she goes through her address book, calling friends and talking it out with them.
Which is an interesting question, but it is irrelevant in terms of the linked post, which specifically points out that the person in question is hiring women at lower salaries because they don't ask and he's following policy, not because he's adverse to giving them higher salaries if they do ask (and he has the flexibility to at least narrow the gap).
Or potentially for the sake of your health, especially if you spend half an hour on the train every morning handling the printouts:

How Trader Joe's Eliminates Thinking In The Buying Process
You're assuming a different selection model, in which a father of two boys is twice as likely to volunteer information if he has two boys: "Pick a child at random, then if it's a boy - say: I have a boy [blablabla] what is the other?"

However, you're doing this on an already selected sample by discounting all the girl-girl pairs. The selection rule in your logic then becomes a two-step "If you have at least one boy, then pick a child at random, then if it's a boy, say: [blablabla]"

Given that, your analysis is correct.

But, seeing as it is a wildly different selection model than what everyone else seem to work with, you should be explicit about it.

Ah, sorry, I misunderstood your question.

You are asking, why the information "one is born on Tuesday" says anything about the gender or birthday of the other, right?

More specificaly, this:

> Let us first assume that it is the older child who was a son born on a Tuesday. In this case the second child could be either of two sexes, and could have been born on any of seven days of the week, for a total of 14 possibilities.

> Now let's suppose it is the younger child who was a son born on a Tuesday. Then the older child could, again, be either of two sexes and could have been born on any of seven days of the week, again providing 14 possibilities. Added to our original 14 that would seem to give 28 possibilities.

> But be careful! One possibility got counted twice. Specifically, the one where both children are boys born on Tuesdays. So really there are only 27 possibilities. And since 13 of them involve the second child being a boy, the probability would be 13/27.

Maybe it helps, if you first imagine all 196 (2 * 2 * 7 * 7, think of four 7-by-7 tables [draw them, it helps a lot ;)]) possibilities. Eliminate 49 of them where both are girls (one of the four tables) and you have 147 possibilities/cells left. Then, in each of the two BG and GB tables leave only one row/column, eg. eliminating another 2 * 6 * 7=84 possibilities.

Now comes the interesting/tricky part:
The last case/table, where both are boys contains only 13 possible cases (instead of 2 * 7)! Imagine a 7-by-7 table, where each row and column corresponds to a day. Mark all the cells which are not in a Tuesday-row or a Tuesday-column, eg. eliminate all posibilities where none of the two boys are born on a Tuesday. This eliminates another 49-13=36 cases.

So, we have a total of 196-49-84-36=27 cases, 13 of which "the other is a boy" and 3/27=1/9 cases where "the other is born on a tuesday".

I hope this makes somewhat sense. Once I've drawn all the possibilities and marked all the impossible ones, it became a lot clearer.

Confirm, yes, but not simply reveal.

I would imagine the salary piece of that is intended for credit checks, not for the next employer. (If you are thinking "maybe they should only give it to certain people," people lie. Oh boy do they lie about who they are on the phone.)

My friend Ian hacked a 'social printer' which is like an alpha version of The Little Printer, blogged about: http://ianozsvald.com/2010/11/06/building-a-social-microprin...

Berg's product looks like a proper, developed version of what Ian made, and does many of the things that were talked about as possibilities when he showed it at at couple of events.

Does it have a massive market? No. Does it have a niche market where Berg can make some money back? I think so. Did Berg see this as a fun internal project to see what's possible and can the ideas it sparked be used by some of their clients? More than possibly.

Berg have a decent following in the crowd of people who might buy something like this. It's not going to make them a fortune, but they're bright people and I'm sure they don't expect it to. It's just as much an advert for what they can do as it is a product in it's own right.
the Wikipedia link you gave says: exposure of a person repeatedly touching thermal printer paper for 10 h/day, such as at a cash register, could reach 71 microg/day, which is 42 times less than the present tolerable daily intake (TDI).
There's a nice writeup here which gives an idea of some of the uses Berg envision for this: sticking things up on the fridge, giving to friends, carrying with you for instant reference without having to wait for an app to load.

I am not sure whether you have ever worked at a startup or not. Your understanding of current software development is what big software service companies do with mediocre programmers. Startups never have army of programmers but few intelligent programmers. And there is nothing bad in using IDE, innovation does not mean to write a solution from scratch. There will always be need of abstraction based on current libraries and programming environment.

I'm just a cynical colonist, but I can't help thinking that an employer asking for that form prior to giving you a job offer is just borrowing the implied authority of government to convince you to compromise your own negotiating position. There absolutely is a point to concealing your previous salary until after they give you a job offer with defined terms. If they learn your salary history subsequent to that, it won't cause them to suddenly renegotiate your compensation package.

So yes, find a different excuse, but find an excuse.
How mobile influences what we by, when we buy it and how we pay for it
That isn't true, although it's how most people go about it.

While a new employer will request pages from your P45, it is not mandatory to hand them over. You can send them to the tax office who will notify the new employer of your tax code. The instructions to do this are on the back, I believe (I recently got bored while processing a new employee and read it all! It was news to me too :-)).

On the contrary - I'm saying that 'removing the duplicates' is counterintuitive and that's why you're having trouble with it, the same as I did.

Besides: please re-read my original post - I didn't mention anything about removing duplicates, and in fact chose to explain the problem in a different way precisely because the duplicate removal thing was so difficult for me to grasp sufficiently to be able to explain it.

Ask yourself this: where does the original 28 come from? One of those 28 permutations appears to be 'Child 1 is Tuesday boy' and 'Child 1 is Tuesday girl'. If you can answer that then you should be able to understand the whole thing.

When in doubt, use brute force:

1BT 2BM 1BM 2BT
1BT 2BT 1BT 2BT <-- Counted twice
1BT 2BW 1BW 2BT
1BT 2BR 1BR 2BT
1BT 2BF 1BF 2BT
1BT 2BS 1BS 2BT
1BT 2BU 1BU 2BT
1BT 2GM 1GM 2BT
1BT 2GT 1GT 2BT
1BT 2GW 1GW 2BT
1BT 2GR 1GR 2BT
1BT 2GF 1GF 2BT
1BT 2GS 1GS 2BT
1BT 2GU 1GU 2BT

I think the issue people are having is that they want to distinguish between the two instances of '1BT 2BT', but it doesn't work like that. Let's say I numbered each of the possibilities written above 1 through 28. If I handed you a piece of paper with '1BT 2BT' written on it, could you tell me which number that corresponded to? No - it would be one of two numbers - so the numbering is additional information not given in the problem statement.

Uh, while I realize the most common method for getting a raise in Silicon Valley is to switch jobs, the idea that it's the only mechanism or the most desirable one is very bizarre.

It also seems to imply that wanting more money is somehow mutually exclusive with wanting to continue working in your current job and/or for your current company.

You're also demonstrating another classic weakness in engineers, failure to recognize social capital. In asking for that information, you put management in the position of articulating their expectations, and when you meet or exceed them, it pressures them further to agree to a raise.

Management isn't just running some simple equation to determine your salary, they're exercising their own judgement as to what you're worth to them and what will keep you working there productively. That judgement can be altered through psychological means.
Please don't take my comment as criticism - I used to do the same when I started out, and it was a lot of fun. Definitely an experience worth going through.

It's fun to reason these things out, but it's easier and faster to simulate, at least at first.

import random, time, collections, pprint

sample = collections.defaultdict(float)

now = time.time()

known_child = ('M', 2)

while sum(sample.values()) < 100000:
genders = [random.choice('MF') for dummy in '..']
birthtimes = [random.uniform(0, now) for dummy in '..']
birthdays = [time.localtime(t).tm_wday for t in birthtimes]
gendertimes = zip(genders, birthdays)
if known_child in gendertimes:
gendertimes.remove(known_child)
sample[gendertimes[0]] += 1
if (sum(sample.values()) % 10000) == 0:
print sum(sample.values())

males,females = [sum(c for (g, t), c in sample.items() if g == gender)
for gender in 'MF']

print males / (males + females)

Result when I ran this was .4816, approximately equal to 13/27.

I meant that the paradoxical nature is not resolved by simply formalizing the statement into first order logic the following way:

"I have 2 children.
Exists child where (Born_on_tuesday(child) and Boy(child))."

(Some other paradoxes completely disappear when you try to write the statement into first order logic. It is not the case here.)

This is what I wanted to say.

How many people do you think have a credit card? I know a LOT of pirates (here in South America), and most of them fit this profile:

- very low or no income
- no credit card
- lots of spare time
- cheap internet connection

Would they pirate World of Goo? Yes. Have they paid for a game? Rarely, they buy CDs or DVDs or game cartridges on cash, but the originals are outrageously expensive for the average consumer here.

Is it an excuse? No. Would they start purchasing once they archieve a decent income level? It's hard to say, but I'm inclined to think they won't.

In my case, I now have a decent income level, but I don't have any spare time to speak of, so I don't purchase videogames (anything past a U$ 2 app on Android).

Sugar itself is not more energy dense than a battery, is it? You need an oxidizer to get energy out of something like sugar. In theory, sugar, gasoline, etc. are much more energy dense, but they need to be very carefully mixed with oxygen to release it all at once. That's why cars aren't generally bombs on wheels even though they theoretically contain sufficient energy to meet that description.

The thing with batteries isn't just the amount of energy that they contain, but that it comes entirely pre-mixed and ready for instantaneous release.

As far as normal batteries withstanding physical abuse, I don't know. I certainly wouldn't try puncturing or badly overheating a regular battery, and wouldn't be surprised if such treatment caused it to release what it has. I could, of course, be wrong.
