Sorry for this test :(
For games, there are two different parts of the physics simulation: Integrator and collision detection/response.

The integrator uses a lot of math. It gives the positions of everything at time t and time t+D, where D is the timestep. The integrator functions under the assumption that no collisions occur.

The collision detection/response system takes as input the integrator's output, namely the positions of everything at time t, and at time t+D. It finds the earliest collision, say at time t+d where d < D, and does something about it -- usually changing position and velocity of the objects involved -- and then re-runs the integrator from time t+d to t+D, again stopping to process the earliest collision.

The important point is that your results are "good enough" if the collision detection just assumes objects travel in a straight line at constant velocity between their positions at t and t+D. The exact path is something that's confined to the integrator, and only linear paths exist in the simulation outside of it.

Of course there are various optimizations and corner cases you have to take care of -- like making sure colliding objects don't immediately register a second collision when the integrator is restarted, and bounding the number of collisions an object is allowed to experience per frame (to handle for example a ball resting in a V-shaped cup from alternating collisions between the two pieces of the cup thousands of times per frame).

And you can optimize since you don't actually have to re-run the integrator for objects that didn't change their physics state (position/velocity) due to the collision.

Language acquisition is not a good example to use here. Our minds are primed with pre-built language circuitry and as children we pick up the specifics of our environmental language effortlessly.

The learning we do throughout our post-infancy lives bears no resemblance to language learning. It is done using that effortlessly-acquired language structure, but in itself it takes hard work and effort. Unlike language, it goes "against the grain" of our evolved instincts. It can indeed be catalysed through judicious social interaction - comparing results, swapping tips, etc. - but the core of adult learning is focused, isolated study. Social environments for learning are a supplement, useful in moderation, but usually destructive and much more likely to result in groupthink, lowest-common-denominator mediocrity, and poor efficiencies in failing to optimise for the wide range of needs and aptitudes distributed among individuals when used in excess.

I avoid this problem by instantly boycotting any site that does this. They clearly have absolutely no interest in serving me content or helping me do what I want to do, and there is always an alternative.
I have some real problems with the knob idea. Firstly, it's not fine-grained enough; I often want to put something in for a time that's not a multiple of 15 seconds. (And the longer you go, the worse the resolution gets.) Secondly, for the rare case when something does need to be microwaved for a long time, it makes inputting that time linear in the amount of time when it could be logarithmic!
The book "Makers: The New Industrial Revolution" by Chris Anderson talks a fair bit about 3D Robotics, in addition to lots of other interesting topics.

that doesn't make sense. why would that be proof of anything? why would they do a relevance search based on the text of their own generated pages, much of which is just template and links to reuters stories, instead of over the raw data they used to generate that page?

Yeah, but... If you are the one teenager who decides it is too risky to jump off the cliff into the river... Enjoy sitting on your own while everyone else has fun - enjoy never getting invited to the river again - enjoy sitting at home playing videogames as the braver boys wander off with into the grass with all the cute girls.

Teenage impulsivity and risk-tasking are reproductively optimal strategies (the actual rates of death and disability from these activities are usually low anyway) even if you like to look down your nose at them. And people who engage in those activities often end up doing just fine in later life, as well-adjusted, popular, confident adults, with a history of sexual success.

Maybe they're not optimal strategies for being a high-performing time-efficient adult, but so what? Natural selection only cares about babes and babies.
Is this the study?

I find this an unnecessary flame. That’s why Apple introduced Smart App Banners for iOS and they work just fine. The problem is just with those redirect you to a separate app download page. http://david-smith.org/blog/2012/09/20/implementing-smart-ap...
I don't agree. I think that interopt should be at a higher level, like services. Putting the ability to integrate code not written for your paradigm is problematic. Pragmatic, but still problematic.

It's a lot like Node.js. Why Javascript? Because it is so self contained that it is impossible to use code that violates the paradigm because its too new. When the designer of Node looked at using straight C or another language, the legacy threat put him off. Same thing here.

I liked Hale-Bopp. I wasn't expecting much after the disappointment of Kohoutek when I was a little kid, but then one evening I looked up and there it was, and it was pretty cool. Hale-Bopp was subtle; you could miss it if you weren't looking in the right place. ISON may be so spectacular that it wold be impossible to miss.
Wow. You must be lost - Hackernews is, as far as I am aware, a site for intelligent, open-minded people who recognise that valuable information may be found in many inconspicuous, non-intuitive locations. People intelligent enough to realise that kids are historically early-adopters and re-shapers of technology, pioneering uses and social integrations which, while dismissed as trivial by ignorant, hidebound adults, often end up exploding into mainstream popularity and defining the future of technology.
I don't know where in the world you are, but at my daughter's high school nearly everyone has an iPhone. Theft is rampant, too -- my daughter's iPhone (one of my hand-me-downs) even got jacked once and she's very careful.

My daughter tells me the trends in this blog post are right on, except the driving force for SnapChat seems to be porn.

Worst part is, most of these apps are essentially browsers. There is no additional content or interesting extra functionality being offered... just same old content, only formatted differently.

So, this concept of installing a new browser every time I visit an unfamiliar site, really is ridiculous.

This is almost as bad as "here's a mobile version of our site, opened automatically for your convenience".

If your site is designed peoperly, my iOS device can browse your "full" site just fine, thank you.
Where did I say I was in favor of using a NoSQL database instead?

Schema changes without simultaneous multiplatform code changes mean I'll have to maintain a consistent API somewhere. As you say, I could do it in the SQL database with (non-portable) views and stored procedures. Or I could maintain it in code. I prefer that. Not only are the tools better, but if I'm going to have my team spend a lot of time learning something, I'd rather it be the language than particular database quirks.
You do, but no one else does.

How small-minded. There are many of us who want to be discovered by bots. We just keep quiet because people like you have such strong opinions and aren't afraid to be mean about them.

Patrick,

Have you ever done anything with direct mail? It's something we don't hear about in the startup world.
You just added "karma cashgrab" to my lexicon.

I think that the HN crowd has more of a Silicon Valley business flavor to it. (As one might expect from a site sponsored by YC.) At the same time, the "Open source/Free Software/Unix Hacker" has a lot of overlap.

My issue with this article isn't its subject matter, but that it's written by ESR.

(Though in ESR's defense, I think it was through reading one of his articles or blog posts that I discovered the PG essays.)
Did you even read the article?

Besides, bloatware doesn't exist for your reason anyway. Bloatware exists entirely because software developers will pay hardware manufacturers lots of money to put their product in front of new users.

I understand the frustration w/the manner in which some mobile apps are advertised, but wrt this statement in particular ...

They clearly have absolutely no interest in serving me content or helping me do what I want to do

... coming from the site owner side of things, I'll offer a friendly counter argument (which has been rephrased in light of down votes): site owners are interested in serving you content, or helping you do what you want to do ... just in a better way.

I agree ads or prompts can be annoying, but to say site owners go through the trouble of developing a mobile app and advertising it b/c they have no interest in serving content or helping the user experience doesn't quite fit. To me, a site that offers a mobile app says the exact opposite.

One advantage of phone calls is that you can have the entire conversation right there. With e-mails you get this back-forth (and of course the constant delay between e-mails) which means that a 15 minute conversation can become a 4 day e-mail exchange.
They want to have push/local notifications. It's like getting ahold of an email, but moreso. I've turned off Javascript to avoid them asking, now I constantly get "turn on your javascript" black overlays from Wordpress sites. Damned if you do, damned if you don't.
Just like I get an intuitive sense that this article is on-the-money, I get an intuitive sense that your comment is wrong. Intelligent, investigatory conversations with individual subjects can be extremely insightful, and speak to much larger trends.

Plus, I think you're discounting the power and spread of trends in youth culture. School is the pre-eminent breeding ground for fads.
Question to the Github team:

Nuuton is currently crawling the web. The plans include crawling Github (actually, Github has a specific and exclisive crawler built for it). Is that permitted? If so, what are the rules? If not, to whom may I speak regarding it? I know DuckDuckGo does it, but I don't know if they are crawlin gyour site or just using what the Bing index currently has.
Yelp app seems like a tough one compared to their site on a mobile browser - they cache previously viewed places, your location, some graphics, embedded native maps, more streamlined search, and just overall offer a better experience.

But yeah, they're in 1% of the world where app is more useful than the site.

Serious question: Is there a "mute" button in any of those patents?

Even though microwaves keep getting control panels with more buttons, they never seem to get rid of the annoying "beep" everytime you press a button. It just seems like a counter incentive to use the microwave extra options.

Microwaves are not the only appliance that does that... I just replaced my washing machine the other day and now it just beeps for every reason (also, I'm pretty sure the beep makes the same sound as coins in super mario, which feels kind of weird).

Why is this? What's wrong with just having a beep when the food is ready (or maybe not even that) like in the older microwaves?
Is it to help blind people? If so, wouldn't the old rotary knob be better?
Looks like good work with some thought having gone into it, although with most such schemes the major gains are usually reaped with the first few simple optimizations.

A mechanical, hand-crafted engagement ring box
I learned about Google a decade ago when "worse than satan himself" brought up either Bill Gates or Microsoft. I worked at Microsoft at the time. Everyone I knew thought it was hilarious, and it spread through the company like wildfire. Within a week or two, everyone was using Google as their default search engine.

(I may be mis-remembering the exact search string, but it was something like that. Keep in mind that Bill's philanthropy had not become public at that time.)
Wow. This is shockingly good and easily actionable advice.
Does this really make you worry that they would tamper with information that mattered? Seems a bit far-fetched to me, doing that would be massively scandalous, and probably illegal.
Oh definitely. The mobile app is almost always a better experience than using the site. But that's not the point. The point is that I'm on my phone with limited time on a slow internet connection, I have requested content from a site and that site has chosen to not show me the content that was expected, but instead display an advertisement. This is unacceptable to me, and rather than deal with it I usually just leave and never come back.

A link at the top would suffice. Or the bottom. Or anywhere, really, that doesn't prevent me from viewing the content I was trying to view.

Edit: In case it's not clear, I think the article is written about full screen overlays that I'm describing. If not, I'm all wrong here and my posts probably don't make sense. I'm totally cool with a site mentioning that they have an app and that I should get it. What I'm not okay with is when you are prevented from accessing the site until you agree or disagree to get their app.
Enjoyed your comment on PRNews Wire, agreed. You're not missing out.

In our experience, releasing press on the traditional "wire" is pretty useless (and expensive!). Unless you want coverage on those strange tech blogs that auto-post all wire stories haha.

Oh, their motives are clear... It's the fact that they are doing absolutely nothing to entice the user to go through the inconvenience.

Yes, I did. I know that's the main reason for bloatware, but the justification, the part that lets them sleep at night, is that they are adding value with their shitty software:

You get to learn from others. What patio11 does may not work for you o rme, but it will work for some people. And for that only, its worth having.
> which uses the neutral algo

It doesn't use "the" neutral algorithm, it uses a neutral algorithm, one that's not based on keywords at all, but PageRank. The finance sites search (presumably) has nothing to do with individual result pages PageRank and therefore it would return completely different results to the main google search algorithm.

Otherwise, why does 'site:finance.google.com facebook "quotes & news"' not return Facebook? Or even 'site:finance.google.com appl "quotes & news"' not return Apple?
Honestly this hasn't been my experience with microwaves at all. To cook something for 1:30, I just press "1" "3" "0" and then start. Maybe I've gotten lucky, but every microwave I've used has the number keypad and a start button.
It feels like a man in a suit with a handful of money asking me to do a favor for him, but he keeps his handful of money.

I feel like Facebook has become the boring Uncle of our digital lives. Nobody really likes it, except for those blissfully ignorant people who haven't realised how dumb they look posting all the time, but we can't get rid of it. I agree that texting is usually faster than Facebook messaging (though because I use WP7 the line is pretty well blurred between the two for me) but you tend to be Facebook friends with more people than you have phone numbers for and/or text regularly. Maybe this is a little different for you because you are still in school, but as a young adult Facebook is the quick, reliable place where everyone I know is stored.

I read a description of the computer desktop as the place which you can always find on your computer, and so the place where unconfident computer users end up storing all of their files. I think Facebook is the equivalent of the desktop for social contacts on the web. Which I think will give it a lot of resilience to unpopularity, so even if no one loves it, it'll probably stick around.
