I'd have to ask my mom to be totally sure, but I'd estimate I ran the machine for roughly 4 years beginning when I was 7 or 8.
I wonder if the use of running as a stressor effected that study? The original article caused heat in the core and upper body(squats and pullups) while short sprints is more of a leg issue.
Anyone else here think that kids should be allowed to spend their childhoods being, well, kids?

A lot of people seem to spend their time as parents trying to teach the things they think their kids should know, but too often these seem to be things that kids need to know to fulfil their parents aspirations for them. Sure cash flow is a useful lesson (though one that I'd suggest could be taught more efficiently) but this feels a bit like a parent pushing someone down a particular line.

Now I'm not saying that this is a bad story, and certainly not a bad parent, just that IMHO the absolute best bit of this story - by a country mile - is that it's something they did together, parent and child spending time with each other. If he learned about cash flow then that's great, but it's not nearly as great as him learning about his dad and his dad learning about him.
marcgravell's post answers it pretty well, but I think he meant to say "there's absolutely nothing wrong with using + for individual expressions". Strings in C# are immutable, so when you do a concatenation by using the + operator, you're creating another instance of the string in memory. The first one still exists even though you now have the new string.

Much like marc said, it's absolutely fine for small amounts, but when you're doing a lot of string operations involving a loop, using StringBuilder will be faster and more memory efficient.

This is a good read about it, I highly encourage it:

It depends what you mean by 'being kids'. My grandfather taught me quite a bit about electronics when I was young (how to solder, what the major components do, etc.) and I loved it. We also did woodwork together. With him I designed and built my own briefcase for taking my books to school in.

For him these were things that I needed to know (he had been in the RAF as a wireless operator in the Second World War (http://en.wikipedia.org/wiki/Battle_of_the_Beams) and so electronics was important and he'd grown up at a time when people made a lot of there own things). For me it was wonderful stuff to know about. And, as you point out, I spent a lot of time with my grandfather.

My parents took me to events organized by the National Association for Gifted Children (http://en.wikipedia.org/wiki/National_Association_for_Gifted...) and also had me do various types of IQ testing. Some of those events involve my best memories of time spent with my father. Perhaps they were fulfulling some sort of wish for me, but I tend to think that they looked at me and realized that these were things that I was going to enjoy or needed.

Those interactions with my father and grandfather really matter a lot.

England have a final chance to avoid a whitewash but the omens don't look good. India have overpowered them in all areas, relishing home conditions again after a difficult few months overseas. After the problems they faced in England this series has shown that India's 50-over game is in pretty reasonable health and it has given Duncan Fletcher another chance to look at a number of young players.

I got 10k overnight when I put www.jobstractor.com on as a show hn a couple of weeks back. That was at the top spot for about 3 hours. NB, overnight to me in UK is obviously not overnight for majority of HN readers.

I'm hosting it on the smallest linode instance going with nginx caching responses and I'm serving almost no images so that worked perfectly for me.
That's awesome. I have a 9 year old son right now (4 kids total ranging from ages 16 to 4 years old) and think this is a great story. Thanks for sharing!
You're Doing It Wrong...Essentials for Startup Blogging
From eyeballing that chart it appears he's counting the whole of Apple's profits towards that graph despite the title being "Operating Profit from Mobile Phones".

I don't consider Asymco an independant source, indeed, they are a key part of the Apple echo-chamber that created this myth. (I mean what kind of pseudo- mobile-phone market analyst gets everything about Android, Symbian and Windows Phone wrong? He even fluffed the iPhone numbers last time, so he's not even a one-trick-pony).
"an absurdly high standard if obeying the law and pushing for updated laws isn't enough"

The law, in case of disputes, doesn't work that you just obey one rule. Different people interpret them differently and often multiple rules apply. Also, laws and their interpretations change over time.

Just because one branch of the government claims the law says you have to do X doesn't mean that's the only interpretation of the law or the only law that applies.

That's why a different branch of the government interprets laws than enforces them, at least in the U.S. When the executive branch tries to circumvent the judicial, you can bet they don't think the judicial branch would agree on their interpretation.
Fantastic article dberube, couldn't have come at a better time for me. Few queries:
a) What would you call a good collection, conversion rate? (Also asked on yr blog)
b) Will this work for ideas that might be seasonal? (eg: I am thinking of selling a particular fruit from India online - it's seasonal and the store will operate only abt 4-5 months. If it's successful, I'll see what else I can do with it, but as of now there are no plans).
So, have you worked this strategy for any such ideas which are not 24x7? How early before the season do you think I should run this. My season is still 5 months down the line.
If I run too early (now-ish) I run the risk of not getting anyone interested as no one is searching for it.
c) Can you give a few figures from your 3 experiments about how many visitors you got from adCenter? And their conversion rates?
Thanks.
I tried "2/0" operation in the console. If this is for programmers, I think the result should be "divide by zero", not "infinity". But I think the idea of the startup is good and the UI is catchy.
In C# strings are immutable , so string + string creates a new string. This means coping both strings into the new result string. That is a lot of copying and can be pretty slow if you do it on large strings, or often on small strings. Especially if you concatenate multiple strings at once (A + B + C + D means that A is copied 3 times, B 3 times, C twice, and D once) StringBuilder is mutable so appends don't recopy data. It is really only a problem if you do it on large strings more than a few times.

On the other hand I am not sure if this is a problem in .NET. I know the semantics look bad but no one said the execution model had to match the semantics. If I remember correctly the JVM has the capability to rewrite the code to the faster version, though I am not sure if the CLR does.
It would be fantastic if the police learned that abusing their power gets them recorded on video, and trying to suppress the video gets the video even more publicity. But it'd be nice if other companies weren't making Google look so unusual for its basic decency.

Any chance you could elaborate on the periods of history that you are talking about?
When I was 9 or 10 we'd go to Costco and purchase the big flats of large muffins. We'd sit around the dinner table and wrap them in cellophane and then send them with my dad to put in his office's kitchen. We sold those things for $50/each on the honor system and made a tidy profit. I hadn't thought of that in a while, but it definitely was a fun adventure.
I'm actually quite reluctant to flag unless an article is clearly spammy. My feeling is that if the article is getting a little traction and stimulating discussion, the normal voting procedure should handle it. If I upvote a couple of honeypots because maybe I do happen to find them interesting, and perhaps for a reason the submitter didn't intend, then I'll be penalized.

I think there is room for honest disagreement. For example, yesterday someone killed an article that I was preparing a comment for when it had reached a karma of nearly 50 and there was a discussion taking place. It was somewhat political (and therefore dangerous), but I find the OWS interesting because it seems to be an authentic movement that's starting to self-organize.

Some 'foreign-born' (non-US) entrepreneurs I know are watching it kind of closely. So, again, honest disagreement. But if I want to keep my h(u) kosher, I'll have to flag more than I want just to make sure.

Again, you forget he's also remixing. That changes the whole game. You may be right if re-encoding was all he does, but it isn't.

You take the 256kbps high quality AAC, and you time stretch and repitch it by a few percent (to match it up with the track you're mixing it into) and probably fiddle the equalizer a bit, to "drop the bass" :)

If you do that a few times, you're losing information, even on a lossless digital medium.

If you use even high quality audiocodecs in between, it will sound like crap. And not the kind of super subtle near-impossible to hear difference between lossless and 256kbps AAC crap, but actual crap. I know this from experience myself as well. The sound becomes really flat, hard to describe, but you notice it when you're playing one right next to another track that hasn't been through such a process. It's like you want to turn it up louder but it's already loud enough. Hard to describe, but it's a real problem if you're playing these mixes on high quality speakers in a club--suddenly the sound is not as crisp anymore, and the crowd notices it too.

If you want to make the analogy with JPEG, imagine re-encoding at 95% quality, but with a few percent scaling and a few degrees rotation in between, before saving again as 95% quality JPEG.

You do that twice, with a quality high res digital photograph, and you're going to wind up with a photo that looks pretty much like the original ... until you make a high res print of it (or zoom in on the screen). Edges that were crisp at first have gone fuzzy, and at places you can spot the typical blocking and ringing JPEG artefacts.

You'd probably get away with it, most of the time, too. But not always, and if you're a digital graphics professional, this is your craft, and the mark of a good craftsman is that they put in the work for the little details that you don't really notice, until they're not there, and how you tell you're holding a piece of quality work.

I wouldn't read so much into this. It's a personal anecdote about the entrepreneurial spirit being encouraged in a young kid. All good parents want their kids to reach their own personal maximum potential. It doesn't sound like Mr. Robfitz was forcing his son to adhere to strict GAAP accounting principles, hustle for cheaper product, or make deals for prime vending machine real estate. This is equivalent to having a paper route as a kid -- which isn't really an option these days.

It's reassuring the Canonical is involved with the UEFI Forum and making sensible recommendations, it's doubtful that BIOS manufacturers would bother making a chip that won't support Linux.

By that I mean do stuff because it's fun and learn things because they're interesting and there to be learned rather than because doing them or learning them serves some aspirational purpose.

I think what your grandfather did sounds ace but it sounds like you agree that the best bit was the time the two of you spent together and the knowledge imparted was secondary (even if it's gone on to be useful).

Obviously things can fulfil both criteria and that's great, but I always think that the important thing is that it's fun and the minute it doesn't meet that criteria it should be changed. Kids spend enough time at school learning things they "need" to know. Let spare time be spare time.

(As an aside my grandfather was a professional football player - while on the surface this sounds like ideal bonding material for a grandson he was big on the hard work element and spent too much time trying to get me to do repetitive drills...)
If you buy a computer, it becomes a company asset and, from an accounting PoV, the money was not "spent". If you lease it (and give it back at the end of the lease) you only had expenses (and, from accounting's PoV, money spent).

Various factors may make one option preferable to the other. Taxes, executive bonuses etc.

If part of the yearly bonus is tied to investing less in infrastructure, an exec may opt for leasing hardware. OTOH, if the bonus is tied to lowering expenses, the exec may consider buying it.
You could A/B on price to get the demand curve.
It goes back to the old 80/20 principle, and most content publishers are realizing what I learned: spending resources to keep a small minority of nerds happy doesn't put food on the table.
The best part was being with adults who treated me like I was an intelligent human being and who explained things to me.

Also, the fact that my parents realized that I was way ahead of the other kids when I could read at three years old and did something about it made a huge difference to my life. I think the most important thing I learnt from my parents about parenting is that parents need to look at their children and ask "what does this child need to be happy?"

I was desperately unhappy at times at school because I was ahead of the other children and bored. They dealt with the problem when they had very little money and were dealing with their first child.

I owe them a huge unrepayable debt for that.
The optimal philanthropy community is trying to figure out how to convey these messages: 1) more money doesn't directly buy more happiness; and 2) more money DOES buy better world outcomes (which probably leads to more happiness overall).

It seems like it should be possible to convince people with some disposable income to put a substantial fraction of their extra money into actually saving the world. Giving What We Can (http://www.givingwhatwecan.org/) is one of the organizations trying to do this. Givewell (http://givewell.org) is doing research on cost-effectiveness -- and there's a HUGE range of cost-effectiveness among charities.
I develop closed source software. Because it is a niche marketplace and releasing our software as open source would probably not work out very well in the end.

However we couldn't develop our software without GNU software tools. Personally I support Stallman. He probably thinks what we are doing is morally wrong, so be it, I still support him because I think his ideas and philosophy changed computing world for the better. It doesn't have to be black and white and can be in between.

We have GNU/Linux -- probably the best, server OS in the world. And it is FREE. Think about that. If anyone remembers what big Unix vendors would charge for it, you'd see how huge it is.

Yeah Stallman is an extremist but I think every movement needs its extremists to push forwards. The ideals of the extremists are probably never realized fully but because they are there, the whole movement (including the moderate positions) moves forward.
Very interesting idea. I need to figure out a way to teach my kids about money and cashflow using something like this method.
However, as cool as this story is, I swear I read it in one of Rich Dad Poor Dad books. Maybe this is the source of the books story. I'm not sure.
Disqus user here. Thought I'd try and answer a few of the concerns raised in this post.

1. "Comment display is broken". That's a matter of opinion. I personally prefer threaded comments as I find it easier to see the structure of a conversation that way. HN and (sorry) reddit use threaded comments, and I'd consider their comment systems among the best on the Web. Youtube, on the other hand, goes for "flat" comments, and, well, have you ever tried to follow a conversation on there?

Either way, Disqus actually gives the site's administrator the option: http://whatever.disqus.com/admin/settings/appearance/. The author is right though, having the ability to switch between the two on the front-end would be super.

2. "Comment paging is broken". Completely agreed on the 900+ comments on pages of 10. However Disqus gives the administrator the option to separate comments into pages or keep them all on one page. I personally don't get hundreds of comments, so I keep pagination turned off.

3. "Login kills comments". Sounds annoying, but honestly that sounds like user error. Disqus does say "Post as..." when you're logged out, which I guess is KIND OF ambiguous, but surely it's the user's responsibility to make sure they're logged in under the correct account if that's what they want?

4. "Newest first is weird". Why? I prefer it. Again, personal preference. And again, Disqus gives the site administrator options for sorting.

I don't want to sound negative, but I can't help but feel this post was ill-thought-out and badly researched. The sites the author is speaking about have apparently just switched to Disqus, so I'm going to assume the administrators haven't got to grips with how the service works yet.

Finally: I just realised that I sound like a PR stooge for Disqus. I'm just a user, honestly.

It is.

Their system could be just as usable if they gave you the root password. They could have provided the App Store by default, as a seal of approval, and let the users get their software from elsewhere as well. The garden is still walled, but you have a door for when you want out.

Now without this App Store exclusivity, they probably wouldn't have been able to squeeze 30% out of the developers. But it wouldn't have affected usability.

I think the "view new comments" problem should be solved by setting a cookie with your last visit and marking newer comments in e.g. a different color when you come back. Letting the user view only threads with new comments is also a possibility.

Having to fall back to flat in order to distinguish new comments is a failure of the system
