I posted a comment there but it never showed up, I guess because it had some links in it.

I mainly recommended reading some educational research that could help improve the khan academy's work.

Especially research in math education.

See for example a report by Harold Wenglinsky called 'Does It Compute?" that found much better learning gains when kids did exploratory math activities and simulations and spreadsheets and so forth. When they did drill activities, their performance actually decreased.
http://www.ets.org/Media/Research/pdf/PICTECHNOLOG.pdf

Then there are these two books (which are free online), the first of which I'd recommend everyone interested in creating educational activities read:

How People Learn
http://www.nap.edu/catalog.php?record_id=9853

How Students Learn
http://www.nap.edu/catalog.php?record_id=10126

In math, it helps to use gestures and embodied analogies and representations of many concepts. In other areas like science and history that helps, too, but also students have a lot of strongly persistent misconceptions that have to be brought out into the open in your videos or text, plus it helps to have supplementary constructivist learning activities like simulations, games, and modeling/design tools (including programming).
What's so striking to me, is how similar the exam is (in range, pace, and tone) to the Ph.D. oral exams I took for a doctorate in English (years ago). That same rhythm. The minute you start to set forth an argument, they get you off onto something else. A lot of times, you're groping for the question.

Few people walk away from them feeling like they did well, but later, you have a sense of accomplishment just for having done it at all.
That's superb then. My big concern for any project like this is that maintenance and upkeep costs end up outstripping the initial layout by a considerable amount.
these are hacks as such on the copyright system, not the patent system
Good argument, except that I don't tend to find success and risk highly correlated. At least not the type of risk that lands so many in prison. The types of things that get you in prison, in general, seem like all-up bad decisions where even the reasonably likely best-case scenario eventually lands you in jail anyways.
Red Hat has approximately 160 US patents.
I absolutely love the ending:

"After this, they decided to pass me, though they said that my harmonic analysis was far from satisfactory. :("

especially when compared to the Fields Medal citation, where Tao is awarded the medal "for his contributions to partial differential equations, combinatorics, harmonic analysis and additive number theory".

Seems he did learn a bit of harmonic analysis in the meantime.
Google+, or how 120+ people wrote a book at the same time
Very neat. I'm happy to see that the demo scene magic still exists. I thought the days of seeing an animated ray traced scene from a 256 byte EXE were over.

This runs fluidly on my Chrome/Sandy Bridge/Ubuntu setup.
> If his plan does succeed and he does end up with the title, won't the taxes on the house be an enormous burden?

Enormous relative to what? The taxes may be less than low-end rent.

> I wonder what his plan is for that.

His plan better be to be paying the taxes now.

If no one is paying the taxes, the folks who want taxes are going to foreclose and boot the guy out. His "squatters rights" won't help him against that.
I'll bet $20 bucks you get shut down by your host for spam complaints.
It's a Cournot game, and it does work - you invest in infrasx up front that will get you a fixed capacity (bandwidth). The airline industry is the same way- an airline buys a number of airplanes up front which get them a fixed # of seats to sell.

To start the discussion, from my view current offerings have some combination of the following drawbacks:

- Hosted solutions seem too simplistic/limited, whereas self-hosted solutions tend to be overly complex

- Complex pricing (almost universally)

I'm wondering if there would be interest in something aimed at people who know what they are doing, but at the same time don't want to code everything from scratch.
If it's 1k, then it's a serious contender.
A lot of the biggest brands see more "search" referrals that are just their brand name going through search engines.

As web browsers replace address bars with search boxes the search engines in a very real sense act like a utility the redirects the traffic flow through a page with ads on it. If you rank fine then no big deal, but if you don't show up for your own brand then that is brutal.

Of course most the sites hit by Panda were not hit so hard that they don't show up for their site name (unless their site was named after a generic commercial keyword where there were lots of other competitors already) but in the cases where it was a lot of those businesses were just hosed. It is yet another way to boost big brands...not only put weight on brand related signals, but make the generics more likely to get clipped by the algorithm at some point.

That forces non-brands to build brand assets & re-enforce them display ads and such. Google is even buying a ton of display ads that advertise display ads. And a lot of those ads highlight how display ads have increased branded search queries for the brands that are buying them.
You can set them to "internal" in the nginx config so they can only be called by other nginx config, not directly by clients. You also need to check the error messages do not leak urls.

Then there is rate limiting etc, depends on the service.
I obviously won't doubt the genius of Terrence Tao, but reading about PhD level research from any other discipline without knowing a yota about it would leave exactly the same impression, even from a lesser scientist. Of course some people are incredibly smart, but there is no need to mythologize their abilities without having any understanding of what they have actually done. Thus I think such an article can only have value for people who at least vaguely understand the mathematics involved.
MP3?

It allowed the Fraunhofer Institute to capitalize on their audio research.
This is why it won't really matter in the end of Microsoft will push for getting patent fees from Android manufacturers. They will simply start selling Android phones in USA, and to spite them they will use WebOS in USA.

This way, Microsoft won't get anything - neither money from patents, nor from their own mobile OS.
Verizon isn't known for being very good at math.

And educational status is strongly predicted by IQ in the U.S. EDIT: And since IQ is strongly influenced by genetics, this latest data suggests the U.S. is creating a genetic underclass. Taken far enough, this is the death of the republic.

You're leaping across logical gaps here. IQ can be predicted by a number of factors (parental wealth, IQ, and education are a few), and research on intelligence is fraught with identification problems. It's hard to believe claims of a "genetic underclass."
Yep, but with either of those, it can still be set back to null :)

Show HN: BugMuncher - Google+ style feedback for your site
Hi Everyone,

I've just launched my new web app BugMuncher - http://bugmuncher.com - which allows any website to have Google+ style visual feedback. (For those who've not used the Google+ feedback tool, it allows you to highlight an area of a page, as well as censor private information and automatically generate a screen shot which is sent with the feedback).

Of course, Hacker News is the first place I've submitted it to, and I'd love your feedback on everything from design and usability to price.

Having seen it written on these pages time and time again, I've gone for the most basic implementation I could, so that I could launch quickly. It's taken me 2 weeks of solid evenings and weekends to get this complete.

Cheers,
Matt Bearman
>I predict several things will be true after this crisis that are not true now. One, I think there will either be a way for the EU to expell a member or to put it under 'federal' control. Second there will be a trans-EU judiciary system which allows for injecting change (either through impeachment, imprisonment, or both) into member states leadership. If such a system existed it would have allowed the joint-EU leadership to demand (and get) corrective action on destructive behavior.

I cannot conceive of a country ever allowing others to have impeachment/imprisonment powers over their head of state. This prediction makes absolutely zero sense to me. Much more likely, we may see some member countries leave the union over the next several years.
The AFQT test isn't designed to measure intelligence per se.

Yes, but as the source explains, the AFQT has several sub-tests, and most of them are highly correlated to IQ. (A few, like the automotive knowledge test, are uncorrelated with IQ.) They claim that appropriate analysis of results on the sub-tests allows a reasonably accurate measurement of IQ to be made.

EDIT: Re-checking the source, they mention that in 1989 the armed forces rescored the AFQT to make it more g-loaded and repeatable. The first draft of the book used the 1980 scoring, but they redid it all using the 1989 scoring because it was superior.
One line debugger in php. $data is the thing you wish to look at.

"The author took the lazy way out, appealing to emotion and outrage, rather than actually doing the experiments to see how google differentiates between subdomains and subdirectories."

That presumes that the algorithm behaves consistently across sites & that the author of the article has dozens of sites that were hit by Panda to do a variety of scientific subdomain tests on it.

Of course, neither of which are actually true.

The only problem with this is that paying for channels isn't quite analogous to paying for streaming access. Felix Salmon points to the obvious difference in reasonable pricing models: a stream aggregator could charge a flat fee but pay variable fees to its content providers.

In this case, you're simply paying up front for the service, guaranteeing the revenue of the aggregator, who then buys your content a la carte.
Can someone provide some context for this? (Besides Terence's Wikipedia page.)
Sometimes I feel like I can actually, like, feel the data moving around. It's very strange.
Ooooh, you're getting me so hyped up for my PhD! I still have to finish my BS (which I'm starting this fall) and Masters before I can get there, but it excites me nonetheless.

This person is gaming a law designed to protect homeowners from spurious litigation†. He knows full well he has no moral right to the property ("adverse selection" codes are not an invitation to utilize unused property). He's taking advantage of someone else's misfortune in a long shot bid to poach property.

It seems weird to me that anyone would cheer him on. Within reasonable limits, a shorter time based hurdle to adverse possession claim is more homeowner-friendly. Texas is on the lower side at 10 years. The only possible outcome to a spate of bad-faith adverse possession claims is for the state to jack the limit up to 20 or 30 years.

† More commonplace application of adverse possession: I build a new garage, but somehow get the property line wrong and impinge on my neighbor. Nobody notices. Later, I sell my house to you. A couple years after that, my old neighbor sues you.
I just do echo '<pre>' and print_r. Works quite well.

> > So the primary purpose in giving people economically worthless education is to prevent them from committing crimes?

>So it's economically worthless to decrease the number of criminals in society?

He didn't say that it was economically worthless to reduce the number of crimes. He asked if the primary purpose of economically useless education was crime prevention.

We haven't established that such education actually does reduce crime, but let's assume that it does. It still doesn't follow that we should do it as there may be other ways to reduce crime.

So, what are the good arguments for economically worthless education? We've got lots of folks who seem to think that it's a good thing, but they're not producing coherent arguments, just rage and non-sequitors.
ABSOLUTELY. It's not about education as commonly taken to mean "college degree." It's about having devoted the effort to develop a skill to the point where you can practice it with high competency.
An interesting view that I got from someone who patents technologies working at a big company, was that software patents tend to protect yourself (the company) from getting sued by other patent trolls!
Maybe I don't understand your use case, but it seems to me your function is masking some other problems. You say you're new to JS, so here's a little unsolicited advice...

If you find yourself retyping the same jQuery selectors over and over, or that the structure changes a lot, then you should be encapsulating that somehow into some other function or object. Instead you're writing a do-it-all function that takes more strokes to type than the original jQuery selectors!

I haven't seen the structure in question, but when I see a class called something very generic like "node", I suspect something else is wrong. If the class isn't specific and at least somewhat meaningful to a person, then you might be solving the problem at the wrong level, using classes when a rethink of the structure might be better.

Also... lack of semicolons is bad style. Lack of braces for if clauses is bad style. Fix it, you'll thank me later. :)
Are you insane? Redhat has tons of patents. They have a position of not offensively using these patents against the community, "a promise" as it was termed when I took a tour of their North Carolina facilities a few years ago. Here[1] is a link to their patent policy and reasoning behind it.

Design Principles and Design Patterns
Good catch. Per Wikipedia:

Lotus Agenda is a "free-form" information manager: the information need not be
structured at all before it is entered into the database. A phrase such as
"See Wendy on Tuesday 3pm" can be entered as is without any pre-processing.

Since that software is from 1992, it would definitely be prior art.
Which patents in particular?
Do you mean _delirium's response? That one seems to be solidly in the black by now.
You're assuming they want to. Look at hulu for example: its parent companies are trying to give it away. It's a bit like trying to say that studios have the resources they need to start their own theaters or that TV networks have the resources to start their own cable companies. I realize those aren't perfect analogies, but the point is the same.

Content companies want to focus on content. Technology companies want to focus on technology. And despite attempts from both sides to do away with the other, that's the way I suspect it will remain for a long time.
In Illinois you get 20 years, and must possess the property continuously, in actuality, open and notoriously and exclusively. The occupation also must be hostile. In all these regards, the burden of proof is on the person trying to claim adverse possession.

My question for you, as a lawyer who might know this: can you beat an adverse possession claim simply by giving the squatter permission? Would a written notice permitting occupation for, say, 60 days, reset the clock on "continuous hostile actual occupation"?
Whether that is good or bad is debatable, but at least it's no trivial patent.
And yet the great irony here is that by being idiots, they virtually guaranteed that someone with the means and time would go and do it. Exact same situation as the PS3 keys.
As much as i like you vision , there are a few problems with it:
1. The basics: housing , transportation , healthcare ,education haven't become much cheaper. And i think it's mostly a question of regulation and politics(big politics or industry power plays), not technology.
2. You gotta to have some money. part time work could be ok, total unemployment is a problem.
G+ for Dummies?
"If it ain't broke..."
Understand, for my part, that I was the guy who would cut vacations short because a project was behind.

Perhaps counter-intuitively, over time this seemed to cause me trouble, perhaps in part because it did not "fit" the broader culture nor others' expectations. (People become "worried" when you do not do the expected, even when the expected is bailing on the project for the sake of your vacation.)

I tried to be "the good employee". As often as not, it burned me. Eventually, I was very much so with individuals (sometimes, 15 minutes of my time could save them a couple of days), but tried to learn to be less that way in an undifferentiated fashion towards the institution in general.

Many institutions become very rigid with regard to culture, expectations, and reciprocation. Essentially, eventually, they "train" their employees not to care. (Once again, it's what you do, not what you say -- again, speaking generally and not to you specifically.)
The problem with these projects Tata is taking up is that by tying to gain some press out of these its making these unusable. The cheapest car was advertized as such a lot and so there was a stigma of sorts associated with it. At the end of the day it was not that inexpensive (with added/needed features) but by Nano is now branded as car for the poor and so people are not inclined to buy it.
I don't think an article where Clinton, a life long Democrat, bashes Republicans is particually useful to a site for entrepreneurs. I am obviously in the minority of with this opinion.
"HOA's suck" seems like an awfully frail case to make against the concept of property rights. I guess you can make it, but then I reserve the right to make fun of you when you get huffy about the eminent domain claims by states that want more commercial developments.
I make lowerTrim and upperTrim functions in any language I work in - change the case and trim the string. Makes things pretty easy.

// PHP example
function lowerTrim($t) {
return strtolower(trim($t));
}

I also have matchLeft and matchRight which take two strings and return true if both strings are non-blank and the shorter matches the longer string's prefix/suffix.

My most-used function during debug-phase is pR:

// especially useful when dealing with PHP arrays/objects
function pR($a)
{
echo '<pre>';
print_r($a);
exit;
}
I think many would support private publicly-funded schools if private schools would adhere to being open to the general public. It's in the best interest of many (if not most) private schools to push out special needs students. They're expensive and generally don't help the "reputation" of the school.

We might be able to handle this by having private schools, but no school choice. That way private schools can't push students out -- if they live in your area, they're yours. Of course this destroys the free market dynamics, which many say is key.

There is just real incentive in education to not have to deal with special needs children in a way that stores and farms have no real analog (the closest analog is farms working with certain easy crops -- which is one reason we see so much corn and soy crops, in addition to subsidies).

The other thing that is interesting is you look at colleges, for-profit colleges seem to be almost universally reviled (especially relative to public and private-non-profit colleges). So far in the US private education of any peoples except the intellectual and/or economic elite has not yielded promising results.

Jefferson most definitely supported public funding of schools, but made clear he opposed compulsory attendance.

In the US today school attendence isn't compulsory. I think anyone could home school.
The Underground Promise Of Turntable.fm
Indeed. Note that there is a huge chunk of population in the gap between special programs for the severely brain-disabled and those who are just barely low-IQ enough to not finish high school. These people are being squeezed to death between the minimum wage and the export of manual labor to other countries.

And who is doing the political squeezing? A cognitive elite that are being efficiently skimmed off and segregated by IQ in late childhood. This bodes poorly for the stability of the nation.
I think a problem with this kind of question is that it requires thinking about counterfactuals. You can't say "this patent is good" without thinking about what would have happened if it had not been granted.
How Hollywood is about to repeat the catastrophic mistakes of the music industry
Every technical word in that sentence is scary juju to most of the population.

This is why I hate to get into small talk with someone I've just met. One of the first polite questions I get is "so, what do you do?" and to judge by reactions its as if I immediately start talking like the adults in a "Peanuts" cartoon. And even if I try to be as nontechnical as possible ("I do website work") you can see they just don't want to continue the conversation at that point.

How about the Google Pagerank patent?

http://www.google.com/patents?vid=6285999

It explains the primary algorithm behind Google Search. I suppose it could have been kept as a trade secret all these years, if not for the patent system.
Apologies, but nothing happens when I view it. Running Chrome 12.0.742.122. I see the initial raw PNG splat, but get nothing but a lot of high cpu and a blank browser screen after running a couple minutes.
