That figure seems slightly exaggerated, Wikipedia states he had $9800 saved when he was 20. And that he made $175 a month from his postal route. If he started his paper route at 15 he would have made over $10,000 from just the paper route during those 5 years. And the article lists several more business ventures he was active in.

Few people start working as early as 13-14, but if we extrapolate the $175 a month (which would be almost $2500 in today's dollars), and you had no expenses you could save $150,000 by the time you were 20, today.

Must surprising here is how well paid that paper route was. Average salary was $200 a month in 1944. Today the average salary is $2500 a month, but you can't earn as much from such a simple job today.

This is why I always walk half a block to pick up a cup of coffee rather than just get one in the cafeteria (also it tastes better). For some reason taking a ten minute walk every now and then and getting some fresh air might be frowned upon, but getting coffee / smoking is a socially accepted reason to do so.

Apple does not provide any API for getting the state of the modifier keys on iOS. I really think this is something they need to loosen up about if they want people to go into the post-PC. We get the point Apple, you want users to be able to do everything an app offers without accessories. But that's orthogonal to replacing your PC with an iPad.

(Especially since the private APIs are already there, they just need to allow them)

Thanks for information. I should have checked the APIs myself, but I couldn't dream the problem was that full keyboard state information didn't get through to apps.

I guess it serves me right for using/loving a closed platform... :-( :-)

I think it's a great idea. But to be persistent over my entire life, there really needs to be an export option so that when smartphones are no longer around and we got neural implants or something I can still make use of the data collected now.

Also 1% of the world seems impossible considering the line of sight when walking around. Even 1% of most countries is impossible.

Due to goal of this app is to save tracks over a person's entire life. The data is saved with super high level optimization. Thus it's impossible to export them to other services like Google Latitude.

However, we're working on database synchronization between different devices. Soon you will be able to sync your data between your iPhone and iPad through Dropbox (also for backup). We also have plan for a Mac version in the future, and due to the power of a desktop computer. Photo mapping or more options are expected to show along the fog map.

That's true it's almost impossible to explore over 1% of the world. So the app doesn't lie to you, right? Anyway, the app encourages people to explore more of the world, discover new places, and know more around where you live. Those numbers really do not matter. It's about your life, and you will know how many places (or area) you have explored in your whole life.

The support for JSON is only validation, otherwise it's just like a plain text column.

A better choice would be to use a hstore column, which is sort of like JSON but we different syntax. Postgres supports indexing hstore subfields, querying on them etc.

You can't click outside the page (ie. on the background texture) to close the modal. But it looks great!

I would just write the code to compute it to arbitrary precision and then tell the interviewer that I would test how many iterations are required and hard-code it.

If they insist that it must be solved at runtime, I would check the size of the computed term (1/(1+2x)) and repeat 'til it's less than 10E-6.

If you're hardcoding it, n will be around 400,000.

That's a lot of iterations.

Besides the slowness of such a solution, that condition is not enough to ensure the first five decimal places are correct.

If you are told the formula to use, you use it. No, it's not the bestest way ever of finding pi. It's to make sure the guy sitting across from you can actually write code, which a scary number of people actually cannot do.

Google Music is a javascript app and works well on the iPhone, the remote etc. all behave properly and it can play while in the background.

My bank is a lot more careful then this. I actually called them a few days ago to get a password, and they asked:

* SSN?

* Full name?

* How long have you been with the bank?

* How many accounts do you have?

* Do you have a business account?

* How many business accounts?

* What's the name of the business?

* Have you set up auto-debit?

* Have you set up electronic-debit?

* To what companies?

* What was your last charge on your credit card?

* Do you have any monthly transfers set up?

* For what amounts?

* Do you have any loans?

* Do you own any investment funds?

* Which?

* Have you reset the password before?

* <My security question>?

* How many two-factor auth thingies do you have?

* Serial number on your two-factor auth thingy?

* Model of the above?

Are the questions I recall. So at least not every bank is careless enough to only require you to name a recent transaction.

I've had this recently.

The banks seem to have worked out that they have access to a reasonable amount of information that they can use it in this way.

The answers weren't easily guessable and there was a threshold so you didn't need to get everything right which allows them to make the questions a little trickier.

The system wasn't perfect - if you broke into my house and got my papers you could probably get past it - but it was a million times better than asking where I went to school.

What bank? Seriously, I will consider switching.

Including business accounts and brokerage accounts (which are often handled separately with different security processes), I've had numerous accounts with many different providers, and never had anything close to that level of security.

I actually use it a lot for watching subscriptions.

However, it's in bad need of an update (it's ugly as sin). So I won't complain if Google releases a version on the App Store instead.

Subscriptions work fine in the very nice mobile version of YouTube. Since switching to Chrome for iOS I have really enjoyed being able to use YouTube's website instead of getting forwarded to Apple's YouTube App.
