On the title, YMMV. Enough people find Disneyland non-creepy enough and even attractive that it stays in business.

On the second half of the article, these are ads. They're going to show people happily doing productive things with their futuristic devices, not gritty mobsters calling in hits from across the continent or terrorists using GPS and Google Images to make sure they're blowing up the right building or all the people left unemployed by the advance of technology standing in a bread line. They want you to feel happy about their corporate branding. If they leave you feeling creepy, they might be overdoing it.
I hate the fact that people get treated differently because of what they wear. It's ridiculous and unfair, but that is reality.

And that's one of the biggest things I took from this piece: Yea, it all sucks and is ridiculous most of the time, but it's the way the game is played. Play it or get left behind.
So someone who frankly hates git and just uses it to clone a repo someone else made with git, while keeping all their own code in other systems, will be measured as 'voting for' git.

Personally, I think both git and hg are broken in different ways, but either still beats svn. Why do git users (as it seems to me) constantly evangelize their product over all others?
> Curiously there aren't a lot of DOD discussions or articles on HN.

How much is there to say, really, once you've got the basic idea?

OOP has always emphasized single objects. Part of that emphasis is that data is grouped by object rather than by field.

For some applications, this style can work well. GUIs are the canonical example.

However, if speed really matters, a focus on individual objects is rarely helpful, because it doesn't support typical data access patterns where algorithms probably want to work with one field for many objects rather than many fields for the same object.

This doesn't just matter for games. If you're working on any kind of mathematical code using large matrices, something as simple as choosing row-major vs. column-major ordering appropriately can make a very noticeable difference to performance on modern hardware with several layers of cache.

One of the nicer things about C++ is that while it supports OOP (at least in the variation that has become most popular) it doesn't try to shoe-horn everything into being an object and is quite happy for you to worry about your own memory layouts if you want to.

Once you've understood that basic point, there isn't really much else to know about Data Oriented Design. It seems like one of those ideas that has been capitalised to make it seem more important than it really is. If no-one had popularised OOP, despite its fundamental flaws in this respect, perhaps we would have just called the DOD approach "common sense"...

On the contrary:

Flash fails in all examples.

What if you screw it up, flood your own basement, and weaken your neighbor's foundation?

That can still happen, regardless of what statutory b.s. the State concocts.

Most often you won't, but the permit is meant to incentivize you against such carelessness.

There's already an incentive against that: liability for the consequences of your actions.

It's the price you pay for the facts that a) some people are stupid, and b) that you have chosen to live near other people, so what you do potentially affects them.

None of that in any way justifies the need for inane government regulations that do nothing but inhibit your freedom because of hypothetical scenarios.
> I'm shocked at all the anti-security people here on HN.

Only by your misconceptions of useful security, and how it can be cobble together from unrelated and broken parts.

> Do you also have no password on you wireless connection

Of course I don't have a password on my wireless. Otherwise how could anyone who needed a connection use it? Sheesh.

The only reason to fear someone on your LAN is because you aren't secure. If you job involves deploying anything Internet facing you can't rely on a firewall to keep the bad people away.

>I would really like to see if the people downvoting have any security precautions in place in their daily lives.

Of course we do. I look both ways before crossing the street, I don't burn candles unattended, I fix all visible "broken windows", and I don't use any measures that don't offer at least a fair bit of protection in the given context. Weak layers are a distraction and a problem, to you.

> If so, they are a little hypocritical.

Not at all. You'd probably (hopefully) object if I came to your house and replaced your smoke detector with a unicorn detector and a bad-stuff detector, even though you now had twice the number of security devices as before.

If you understand why you'd object to those you'll start to understand why I object to what you see as security measures.

> ..and if we had no security, would it be any better?

YES!

Than fake security, I mean.

If we had no security we'd know it and we wouldn't take pictures we didn't want seen, or write email we didn't want read. A realistic view is always preferable.
Please. This is my killer argument, and if you know of a way to defeat it, I really want to know. I wouldn't want miss such an opportunity to actually change my mind.

The paperboy as we fondly remember it (I want my two dollars!) might be technically illegal

I was a paperboy. Technically, I was an independent contractor. Therefore, they had no legal responsibility to me. Of course, I was entirely responsible to them, and I wasn't allowed to run my route like a proper business (e.g. no payment for three days, cut them off). Basically, it was training for being taken advantage of by large(r) corporations.

Nowadays, it looks like all the paper delivery around here is done by adults. One drives while the other walks and tosses papers at 3am. Better experience for the customer, billing is automated, and no kids are exploited. A loss of an American tradition, perhaps, but a tradition which became a mild form of exploitation rather than empowerment.

Incidentally, on the subject of machinery, tasks should be relegated by age. A twelve year old is probably capable of handling basic lawn machinery, though 14 or 16 is probably better. An eight year old can certainly rake leaves, dig holes, and trim bushes. A four year old can rake leaves and move rocks. I did lawn work for my grandparents every summer and, despite being disallowed the riding lawnmower, I was reasonably effective.

Another point I'll make is that both lemonade stands and paper routes are basically dead-end. You can't franchise a lemonade stand. As a paperboy, you can conceivably upgrade to a scooter to cover more distance, but you're still stuck personally collecting money from all the deadbeats. It's really just wage-labor under an entrepreneurial fog.

IE9 manages to keep up with Flash pretty well on many of the Canvas examples on my system, whereas Chrome has much more across-the-board problems compared to Flash.

I think the win that Flash still has over Canvas when it comes to gaming and other blit-heavy applications isn't even so much the fact that it is "faster" (usually), but that the peformance is more predictable.

It isn't that difficult to come up with a canvas demo that runs great on one browser and unusably slow on another. Flash performance certainly depends upon the CPU class, just like anything else -- it'll perform differently on a modern desktop vs modern laptop vs smartphone, but with canvas you have that worry as well and then you have to multiply it by how much variance there is in performance across all the browsers.

Of course, the flip side of that is that sometimes there just isn't Flash at all on a particular platform, so it will be nice when canvas is mature enough that it is just taken for granted that the performance is pretty good for whatever platform it is currently running on, but we certainly aren't there yet.
That doesn't answer my question . . . It wasn't rhetorical.

Then...don't?

If you were genuinely concerned, you could always ask them how they made it, and if anything seemed fishy (improper cleaning, ingredient prep, etc) you can always walk away. The existence of the stall isn't in itself a hazard, and in the majority of cases, there won't be any problems at all.

The problem is in the 0.1% of cases where someone didn't wash their lemons, or has been snacking on peanuts near an open container or something similar, and there's a major incident. Risk/benefit analysis suggests you should avoid it and go grab a coke instead, but there's nothing stopping you picking up a cup of lemonade and tipping it down the drain if you wanted to encourage some neighbours children to pursue their business ideas.

I agree that there's less to learn, but also there's much lower risk to the children (gardening work will often involve pointy things and/or power tools), and it could well be a good place to start.

I'm not sure how the licensing issue could be dealt with, since AFAIK a minor can't enter into the majority of contracts that might be necessary to obtain permits/handle licences.
Kindle Fire: Still Worth it With No Ice Cream Sandwich?
I've been wanting the Kindle Fire since before they announced it, but now that I've learned it's a forked version of Android Honeycomb, and won't run Ice Cream Sandwich, I'm not really sure what's happening here any more.

What do you think? Is the Amazon Kindle still worth it?
Right, but in the long run, a really obnoxious guy who is right about the market more than everyone else could probably end up running money, using other people as buffers. A small hedge fund really doesn't have a lot of overhead, so one obnoxious genius could work with 2-3 other people.

There are lots of roles in finance where connections and likability are probably primary (once you pass a certain level of competence), though.

I continue to be unimpressed with SFLC's understanding of copyright law. In particular, they are using some kind of definition of "derivative work" that doesn't match what the courts use, or what most other lawyers use.

As near as I can tell, what they are doing is confusing evidentiary factors that would be used to support a case for copyright infringement with the actual elements of copyright infringement.
The analogy would be even better with bread in stead of beer.
You'll only get junior developers from something like this. That may be what you're looking for, but it might not be what you need.
It's not Utopia that's creepy in that video. It's the combination of bad acting and advanced technology.

Go to the college and talk to them about testing out of some classes. CLEP is one of the big names (for such tests). There is (at least) one other, but I don't recall the name. Colleges these days increasingly offer classes which are work-friendly in terms of scheduling. I'm 46. I've dropped in and out of college and off a lot over the years. Divorce and health issues have so far prevented me from completing my bachelor's. However, I have completed my Associate's, a Certificate in GIS (the equivalent of master's level work) and some other certificate from a technical college that my employer put me through. I never did get a GIS job like I had hoped (due to my lengthy health crisis, basically) but still totally worth it.

Sigh, these sorts of things always force you to change how you develop and don't really work for mobile web dev. This wheel seems to been re-invented far too often.

Alternatively:

sudo pip install watchdog
watchmedo shell-command -w -c "make" -i '*/.*' -R

Where "make" is either for a makefile or some other build script.

And then just put live.js (from http://livejs.com/) as a script inside your pages.

This works anywhere with basically any stack (i.e. if you had some strange alien CSS preprocessor as long as it can be processed with a command you can use this), integrates into your normal build system and requires no browser plugins or proprietary binaries.
In Chrome the fps reported good numbers but many of the examples were jittery. In IE9 all the demos ran smoother than Flash though except for the blitting one.
How so? :)

Nielsen's law is basically saying that the highest available bandwidth anywhere increases exponentially. That doesn't mean that any one customer gets an exponential increase, or that the majority of customers get any increase at all. And backbone capacity increases don't help unless they significantly outpace the growth in the number of subscribers.
In most browsers and with Intel based hardware you can only achieve 64 callbacks per second (or one callback every 15.6ms) even when using setTimeout(f, 0). [1]

Maybe the task of reflowing the document just takes significantly less than 15ms, so that it always finishes before the callback is executed. But I don't know how browsers are programmed so this is just a guess.

>I believe many times technologists focus too much on the platform than delivering a product.

Well, that's for one of two reasons. First, platforms are more technically interesting than products. A product just does one thing. A platform can do many things, and it's the adaptability and extensibility of a platform that makes it more interesting than a product.

Secondly, often technologists aren't so concerned about the individual product as they are the about the market for products. A platform with standardized interfaces and specifications will have a more robust market of products running on it than a platform with proprietary interfaces and specifications.

> I haven't met many happy 60-ish childless couples.

I'm admittedly generalizing here from what I've seen and experienced, but I suspect that you haven't met them because the childfree (i.e., those who are childless by choice) tend not to inhabit the same social circles as parents. Those who are instead childless by circumstance may well be the very image of unhappiness.
I think sports is 'mostly' a meritocracy. You don't just walk into the first team of any of the top European leagues. And Beckham fully deserved his place in all the teams he's played in so far - just ask Capello. Capello initially refused to play Beckham (for whatever reason) in 2007, but would now acknowledge Beckham's role in helping Madrid win La Liga in the same year. I agree teams factored shirt sales when bidding for Beckham, but he couldn't have built his brand without being a top player.

Depending on how you define success, Kournikova was successful. You can't qualify routinely for grand slam tournaments unless you're a top tennis player - you get there purely on merit.

F1 is a different matter entirely. For all the love I have for it, it's hardly a pure sport. But even then, the top drivers do win the top drives. I remember telling my Spanish friend that Alonso was going to win the championship some day, after seeing him routinely out-qualify and out-race his teammate, and drivers in better cars.
The quoted $18 price plays no role in the story; the point is that it was bought on credit, with the people taking the credit being insolvent, and that there was a systemic bias towards issuing them credit anyways.
Misleading intro to article. The expansion of credit was not due to over ambitious politicans who wanted homeownership for the poor. It was fueled by lax accounting and regulatory standards which expanded private securitizations of mortgages (did not involve freddie and fannie). This generated money which went into legislator pockets though.

It is true that subprime products gave politicians something good to speak to poor constituants about but credit standards were never allowed to drop very far for the federal agencies (other than FHA/VA etc) and their marketshare of mortgage bond issuance dropped as a result.

Despite being a highly regulated industry too little govt involvement in key spots was a primary cause of the bubble not too much.

I also am not entirely sure how swapping beer for mortgages makes the situation easier to digest.
The difference between Time in this scenario and Gold, is that the value of time will be based on artificial scarcity.

The scarcity of Gold on the other hand is very real. Gold is limited and while it is possible to synthesize gold, the cost of doing that is great and does not scale.

Which is why I think the world you mention is impossible: we cannot even stop the piracy of music. Artificial scarcity is not sustainable. Once all the people will be able to live forever, they will live forever. What makes you think these "clocks" will be unbreakable?

And even if the technology will be perfect, do you really want to have on your hands a huge angry mob of people with less than 24 hours to live? Good luck with that ;-)

Isn't this like having a function that explains very well data that is within an observable range, and then stating with confidence that that function also applies to data in a range that is unobservable to you?

Yes, that function may hold outside your observable space, but it may not. We can't simply state as fact the predictions that come from assuming that this function applies outside our observable space.

The Kindle Fire is worth it, for what it is. Since they have their own App Store, they'll be approving their own apps, which could severely limit its capabilities, but, in the same breath, it won't be worth it because it doesn't have access to the same android fucntionality that Google's been working on.

If you're looking for a web browser in a tablet, and a way to view and read Amazon-based content, the fire is the ticket.

If you're looking for an android device that will accomodate the latest and greatest android offerings, the kindle fire isn't the ticket.

I first seriously(?) learned how to code by finding a used Pascal book and reading it thoroughly. That was some time after getting my first computer and not knowing where to find a compiler! (I'm not counting forgotten Logo from summer class long ago or using elaborate triggers in a MUD.) I had serious learning problems getting far past that unguided. Finally learning C from some lecture notes was a growth spurt though I had looked at some C before that. Trying to calculate the fewest coins to add up to a sum and finding optimal new coin took like a couple weeks! LOL

Sure it does.

The market for beer bonds doesn't exist if there isn't an ever increasing ceiling on the price of the asset that bond is backing. In this story beer went to $18 and everyone was willing to pay it, not because it was worth $18 but because no one was having to actually SPEND anything (yet) for it (except those buying the bonds).

It may not have been the most important thing, but you need the "bubble" in the story for the bubble to "pop":)
