Define "the best students." With my assumption of measurement by derivatives above, those would be the students whose knowledge changed the most during the lesson—those who knew the least before and the most after. Thus, teachers would be jockeying for the students most in need of education, not the students who already know the most (because the pretest scores would reveal that the teacher hadn't changed their knowledge very much over the year.)

Rather than the current No Child Left Behind policy of regression to the mean, this would assign the most "learning-intensive" teachers to the students most in need of learning, and assign the students who self-study or are otherwise pre-informed to teachers who are more "lenient", likely diving further into interesting sidebars and tangents. Both groups would be better off for it.
Here we have a researcher, who has spent 40 years collecting data and building a database of tree ring measurements, recanting the results of his work. Shades of Galileo being forced to recant his view that the earth orbits the sun under pressure from the Church. The deniers ought to be ashamed.
ColdFusion Snippet - Two Dimensional Arrays
Is this a joke? VB may be "easy" but it's terribly verbose. VB 6 was end-of-lifed two years ago. Pascal was a good idea 30 years ago. And Delphi's designer was hired by MS to build a better language 14 years ago, which became C#.

Now, let's look at the languages with momentum. MS has bet the farm on .NET and C# is the primary vehicle. The Mono project is going strong. The most important web programming language (if brain damaged) is PHP. And the language underlying ALL OF COMPUTING AND THE INTERNET is C and C++.

Um.
CPU hog warning please?
On the last point: does that actually happen, though? That's what idealized economic theory would predict, but large corporations' internal structure is quite far from idealized economic theory. My guess would be that if you were able to set up some experiment where one employee cost $100k while somehow having $0 payroll taxes, while another employee cost $90k plus $10k in payroll taxes, the employer would, more often than not, hire the $90k employee.

This happens already, I believe, as regards families. Employees with families cost more in health-insurance benefits than single employees, if the employer offers to subsidize a percentage of health insurance (as most do). But employers don't pay single employees of equal qualifications commensurately more, despite what economics would predict.

I'd say it takes a good part of that. Some is direct: military, police, court, and prison spending accounts for a huge proportion of total government budgets, more than half. And some is indirect: there is only some level of inequality people will tolerate before there's rioting and seizure of property, so things like social safety nets indirectly serve to guarantee property rights by mollifying discontent.

Best way to store poem text and audio
Guys, I am making a stored browsable and searchable collection of poems with text and audio with other infos like source of book date and type and like that. For now I have been storing audio by making new folders based on classification and keeping text in spreadsheets with all other infos in table. But it would be better if there is a way to store text and audio in same program or like that but also allows me to do text search.

How to make an array of arrays in Perl 5:

@aoa = ( [ 1, 2, 3 ], [ 4, 5, 6 ] );

How to make a list of lists in Python:

lol = [ [ 1, 2, 3 ], [ 4, 5, 6 ] ]

How to access the second element of the second array in Perl 5:

$aoa[1][1];

How to access the second element of the second list in Python:

lol[1][1]

The difference seems to be nomenclature and Perl's use of sigils. Where's the "horribly outdated" design?
In a lot of cases, people already value the product, the issue is with distribution and being able to get their hands on it in a convenient fashion.

I've tried hiring using Google Ads with keywords relevant to some advanced techs we use and if you are in my country, you get an ad. It didn't help much with our immediate hiring needs but it worked better as brand advertisement - it generated some discussions and I believe it did help us hiring later.
To be fair, Sony is hard-pressed to provide hardware at a loss just because it's being used for good. As a company they need to stay profitable and all of the good press it got for being a research beast was not translating into positive returns. So it was good while it lasted but unfortunately the free market dictates this change.
I suspect our opinions may be the same, it’s just that our definitions of “gaming platform” are different. I take the consumer view (a good gaming platform is one where I can buy the newest and best games) while you might take the developer view (a good gaming platform is one where you can develop great games). I have no opinion on the second point, I’m just saying that from a consumer’s point of view Linux is indeed a gaming platform that sucks.
Exactly my point..it's not going to lead to better software though is it?
And teachers gaming the system won't lead to better education.
California has amongst the most extensive urban sprawl in the entire country, so it's strange to think of it as a place where zoning and property restrictions restrict supply. LA is world-famous for its urban sprawl and car culture! And in the Bay Area, you can drive from Millbrae to Gilroy while going through nothing but endless suburbs for 65 miles. Meanwhile, Portland has super-restrictive growth and zoning policies, and is much cheaper. So I think there are more factors at work.

It's really frustrating the way these huge bills get created. You might have 20% good ideas, 20% toss-outs to the PACs that elected you, 20% earmarks, 20% total crap, and 20% unknown.

Is a bill like that worth voting for? You can pitch it as solving a huge problem, being an indication of rampant corruption, making progress in a key social or political movement, being a vehicle for bringing money to your state, or being a terrible mistake. Fact is, it could be all of these. Then congressmen can use legislative tricks to both vote for and against the same bill, effectively rendering any kind of simple debate meaningless. Which is the exact reason why it's constructed the way it is.

I think in terms of startups, this is the worst bill I've seen in years. And while I'm sure professional Angel organizations are all on top of the changes and such, we need to be moving in the exact opposite direction than this bill is taking us. I think real reform is needed, but I am deeply worried that the underlying theory here -- that market risk can be managed by committee or legislation -- is deeply flawed. Adding to that structural problem I have is all of these other really bad tack-ons, like giving the FDA more control over the vitamin and supplement business.

Bad. Bad. Bad.

Aishwarya Rai Bachchan at 63rd Cannes Film Festival Photos
The 36-year-old former Miss World Aishwarya Rai Bachchan attends the 'Robin Hood' Premiere at the Palais des Festivals during the 63rd Annual Cannes Film Festival on May 12, 2010 in Cannes, France. Aishwarya Rai who is regular attendees at Cannes Film Festival was arrived with Eva Longoria at Robin Hood Premiere Show.
Interesting point made by the author.

Its something I've wondered about. What would stop Google from degenerating? Its an interesting question because the reason we use Google (good search) is not how they make money (ads). They are related, but not the same. If you have a product that people buy, you have to keep making it better.

So what stops google from splashing their entire page with ads (to earn more), or not being the best in search (as long the ad revenue is flowing)? I think the author gives a good reason why google wouldn't do that -> because users will easily change their default search engine
I think it should be used to showcase all of YC's investments.
Partly that's because of our fear of "socialism". We'd prefer to give away $50 in subsidies, allowing people to buy some sort of private service, versus having the government provide it for $30. See: EU countries' national health-care systems versus our Medicaid+Medicare+SCHIP+etc.

Advanced Google Search tips and tricks
I'm sure Facebook would like to be some sort of all-emcompassing platform, but its main value has always been the "self-updating address book", which is useful if and only if almost everyone you know is on there. All the other stuff, the messaging and photo sharing and toy apps and personal information pages and so on, can already be done elsewhere as well or better than Facebook does it, except for the automatic links to friends and the security/networking that come with that. If Facebook either loses a significant number of people in someone's friendship group to a rival system or loses the privacy/networking effects by making almost everything public, its value is going to drop very quickly for a lot of users and a vicious circle of people leaving is likely to follow.

Yeah, you're right. Currently Twitter doesn't offer the full firehose stream to every developer and I use several less populated streams to get the replies. I think that over time I'll be able to get all the replies.

As for the tweets that aren't chained together, this is really tough to do. I'll think about it.

Thank you for the feedback, really appreciated!
I am a young developer working primarily in Perl.

"Sony's decision had no immediate impact on the cluster; for obvious reasons, the PS3s are not hooked into the PlayStation Network and don't need Sony's firmware updates. But what happens when a PS3 dies or needs repair? Tough luck."

So basically, it's pretty much the same as if Sony just stopped selling/repairing PS3's. Hardly seems terrible doom and gloom to me, and certainly not something anyone should be angry at Sony for.

They got a ton of cheap subsidized hardware, and can use it until it dies.
it great tips of many who don't know how to use search engine or optimized result.
Sadly true, but it is institutionalized in unions and civil service (and even worse in unionized gov't jobs like teaching).
Some people I know have had better success with craigslist than the others, precisely because it mainly results in local competition, rather than competing against people in India. However, it depends on what area you're in. The best paying areas tend to involve at least some aspect of design, and small-business clients. It's actually great for pure-design/no-tech gigs, like designing someone's logo, or doing a storyboard.
Non-unionized employees can also be paid less and receive less benefits which is great. Because that's how you find the best of the best - offer next to no salary or benefits. It's so simple - you task these underpaid drones with teaching a meaningless standardized test to kids who are physically and sexually abused at home and come to school without a jacket (or breakfast or a packed lunch). If the kids don't do well, clearly it's the teacher's fault and they should be forced out immediately, which will be easier without union representation. Also, to save money, it's important to threaten older, experienced teachers with cut retirement benefits if they don't retire early (happening in MI) so that cheaper, newer teachers can be hired in their place. And even though all studies show that academic achievement starts at home, don't blame the parents. Ever.

I generally agree with the sentiment of this article, though I feel like I need to get better at using git anyway. It's a leaky abstraction and very unintuitive, no doubt, but after using Git regularly I just can't go back to subversion, the workflow in Git is so much nicer (when everything goes as expected, at least...)
Ask HN: Open-source web apps
This is a proposal to all the developers at HN who believe in open-source coding. There are a lot of open source desktop apps but no open-source web apps.

I would like to initiate a project where all developers who wish to participate can join together in creating web apps.

I am proposing that we get together and build simple, usable web apps that others can build upon and extend to meet their needs.

The creators of the applications can still offer a paid hosted version but they must also offer a free version that anyone can self-host.

What do you guys think? Would anyone be interested?
Forget that, the "deactivate profile" function barely works.

I deactivated my profile last Monday. Out of habit, today I went to Facebook from another computer that still had a session cookie. It reactivated my account, no questions asked.
I actually tend to find the opposite: I know lots of CS majors who love perl and C, and lots of web-design-focused non-cs-majors who love ruby, python, and php. Both groups are approx the same age (late-20s/early-30s).
How to Ensure Longer Existence of Links
Link building is an ongoing process. Usually when a new link appears, it remains on the site for a period of about few months and then it abruptly disappears from the page for never to be seen again.
The most important result of this endeavor would not be the implementation, but an open, de facto standard protocol. Has anyone seen any mention that such a protocol would be formalized?

Vote Forbidden Tree
"Forbidden Tree," the seven-minute film from Iran by Banafsheh Modarresi, now at Cannes short corner contest, is a story about a land where love is forbidden and freedom a distant memory. People dare not stand up for their basic rights, so they have adapted themselves to living in a harsh environment. In the process of forgetting about love, their faces and figures have become transformed. In fact, the less love they have inside the more they come to show it on the outside -- indeed, some have even turned into animals.
Articles and comments that are upvoted provide more marginal utility? Or are they simply more pleasing to the reader?

If I tell you that your business model sucks and that you should try selling shoes, you (and others) may be immensely displeased. But then you may try selling shoes and make a fortune.

Nope. Marginal utility and immediate gratification (or ability to predict what a crowd likes) is not the same thing.

An easy way to deal with this would be to say, preferably in the promotion video, something like "if we receive the desired $10000 amount then no further donations will be accepted", or to nominate a charity which any surplus donations would go to. If they receive a large amount of money and then don't deliver much at the end of the summer then there could be a lot of negative publicity.

But I wish the diaspora developers well, and hope that they deliver something which is at least a foundation for a privacy respecting social network in future. Clearly there is a need for some software filling this role, and enough people are fed up with the status quo to put money towards a solution.

Sometimes we convert PDF to word just for one time. So, what we need is just an online converter because we don’t use that frequently as people do in the office. And due to that condition, you can Google “convert PDF to word” and select an online one. But can they ensure the privacy?

I'm officially disappointed in Portal, and glad I got it for free. Everybody in the trade press said it was this extraordinary thing: a short but sweet puzzler. Sadly, the game/dev's roots as a FPS house really shows here. Not all of us (especially us older people) have the reflexes anymore to do some of the real time tricks required to solve the last couple of stages. sigh
it's not really "investing" though, is it. it's giving people money. there is no exchange of equity involved in the kickstarter transaction (nor is it allowed, according to their TOS, I think).

I've got a lot of time for Panic, but they could have done this with any device that plays digital audio, an iPod, a Zune, any old laptop or desktop machine. The iPad adds nothing to this apart from clever marketing since it is the device de jour. Nothing against clever marketing, but usually Panic's clever marketing assumes you're a smart geek too. This fails that test quite badly and is just randomly crowbarring iPad into a story that's mildly interesting without it. (edit: just to be clear the song, and the fan-made music video are amazing, but several years old. The mildly interesting bit is just them recreating it on their particular machine and using a digital device to load digital data via analogue audio)
