Once you manged to grok the basic stuff about Typeclasses, Functors, Applicative, Monads, Monad Transformers, different notions of recursion, a minimal understanding of how lazyness can be quite tricky, the multitude of different ways of how errors and exceptions are handled in various libraries, and perhaps basic STM, Haskell has a tendency to become even more complex. If you want to do efficient IO and prevent space leaks, you have to learn about Iteratees, Enumerators and Enumeratees. If you wish to create GUIs in a bearable manner, its imperative that you learn about FRP and Arrows eventually. Then there's the innumerable amount of language extensions to Haskell of the GHC flavor, each of which comes with only scarce documentation and examples, but with a lot of theory (Fundeps, Type families, Existential types, GADTs ...). But there's more: Comonads, Kleisli Arrows and probably things I haven't even heard about. The whole point being: If you want to be able to handle 'real world stuff' in Haskell, its not enough to stay 'mostly pure' and use StateT, unfortunately. I like Haskell - I shudder when I think of C, C++ and Java - but at this point in time I find it overwhelming.

I'll never understand why people are so afraid of having their information sold by Facebook in order to better target ads to them. Do you like seeing shitty ads that don't matter to you? I don't.

>You shouldn't be able to license a "technology" unless it's a marketable product.

You just gave this long explanation of why it's reasonable to charge LG for Super AMOLED licensing. AMOLEDs are not marketable products. No one buys an LCD randomly to keep in their pocket. They buy a phone that happens to use an AMOLED display.

Regardless of whether the patents in question are valid, your argument makes no sense. Basically no one ever licenses entire products except for end-user licenses. When it comes to licensing for other companies' production, they generally license various technologies which are not by themselves marketable products.

in just 8 hours, they built the app…having already spent more than a year on natural language processing and machine learning. in 8 eight hours they have a working but unpolished simple app that plugs into a lot of research. does anyone else find the sensationalism absurd? "just 8 hours"

and a question for HN—what is this fascination with techcrunch? if there is a story out on the interwebs and techcrunch has covered it, it's usually at the top. is it because they do venture capital pieces? is it because green is (was) the color of money? is it because michael arrington held some sort of strange fascination by tech culture at large that has remained now that he's been ousted?

i humbly await the downvotes and replies.

Right, I believe this is a function of how much of the magnetic flux does not encounter the superconductor. But IANAP, just a former EE, so I don't know that this is 100% correct.

I use unmanaged dedicated servers.

Going price for a dedicated Quad Core i7, 12 GB of ECC RAM, 4x2TB is under $150/mo. That's a wicked cheap price for those specs.

Obviously if you are going from $10/mo hosting, you won't bite the bullet on a $150/mo server, but it's the only price point I know.
I'd imagine whatever force is needed is proportional to the strength of the magnets. Given that he can pull it off I can't imagine that specific setup requires all that much force for it.
Coming from Python/Django, I forgot that the Rails crowd does not have a templating language (as part of the framework, at least). So I was kinda wondering what "future" was being talked about. Even Java frameworks have many template systems.

My quest now is to actually push all the rendering logic to the client. The project I am currently working on is already very heavy on javascript, so there is no way to do "graceful degradation" for browsers without javascript enabled. Ideally, my server should just respond with JSON (or XML), and the client takes the response and renders the HTML.

So far, the biggest pain with this is to debug a template. Using the jquery tmpl plugin, you just get a blank screen if your template is wrong.

If someone knows of a good js templating language that offers some decent debugging functionality, I'm all ears.
Isn't this sentiment true every time Facebook makes changes to their UI? There's always some user backlash immediately following its release, but after a few weeks everything settles and returns to the status quo.

I have no doubt that Facebook extensively tests their changes to the UI features with a focus on how much more time people spend on Facebook. For example, the lightbox photo UI was panned as being confusing and slow, but brings in an extra billion (+5%) photo views a day [1].

While 48% of teens claim that they try to ignore or see no real value in the ticker, I bet that a large chunk of them are clicking on it (whether they consciously want to or not).

We haven't even SEEN the local merchants bail on Groupon yet, and that is going to happen. Believe me. I deal with disenfranchised Groupon merchants everyday, and they almost all hate it. The craziest part is they're all considering doing it AGAIN just because they feel blackmailed into it by the "if I don't do it, my neighbor will. At least this way I might get something out of it" situation.

I love selling an alternative, because it sells itself. You're NOT like Groupon? SOLD!
This is like claiming that Latin is a more useful language than English because almost all of the Latin you see is excellent writing by amazingly talented authors, whereas in English you have all these badly spelled text messages from your friends and Tweets from famous people and love notes from your sweetheart and baby babbles and second-grader scrawls and five-paragraph essays by high-school sophomores and job offers and breaking news and Reddit jokes and HN rants and Wikipedia articles and text-adventure games and comic-book speech balloons and bestselling dime novels to wade through in order to get to the well-written stuff.

And, of course, you rarely hear Latin mispronounced. In fact, the only thing rarer than hearing Classical Latin being mispronounced is hearing it being pronounced correctly. E.g.:

http://en.wikipedia.org/wiki/Julius_Caesar

In Greek, during Caesar's time, his family name was written Καίσαρ, reflecting its contemporary pronunciation. Thus, his name is pronounced in a similar way to the pronunciation of the German Kaiser.

On the bright side, Latin does embody a vast array of fascinating tidbits like that one. Plus you can read two-thousand-year-old poetry and cast spells like Harry Potter.
Can you please explain how you jump to an understanding of how our brains our wired for 'private' issues and not 'public' ones? I know plenty of individuals whose minds operate in the context of society. Language isn't private. It's shared.
That's why Tim Russert's Red States/Blue States map (http://en.wikipedia.org/wiki/Red_states_and_blue_states) is so significant -- it exacerbated the us vs. them mentality and created a deeper visual divide throughout the country. It is so effective because sports has already conditioned us to think this way.

The us vs. them mentality enables parties to get away with bundling "good" policies with "bad" because Republican voters will go along with the Republican party line even though they may not agree with all of the positions, likewise with Democrats.

The parties cycle every few years so the "good" stuff that doesn't pass and the "bad" stuff that gets pushed through is blamed on the other side. This wouldn't be so pervasive if we would focus on individual issues and not parties.
Agreed. Several people (myself included) had already submitted the direct link to the youtube video. This blog adds absolutely nothing to the video.
The huge upside/downside for me is the sheer power of Java.

It has a huge amount of capability and speed, and it forces you into a very structured programming model that works well for large projects. The same applies to eclipse.

But for small projects it really is a ten ton hammer. The overhead of setting up full class hierarchies, GUIs, etc. for even the simplest application is huge. Again, the same more or less applies to eclipse.

The problem is that a simple up/down vote system is too crude.

- low effort for drive-by downmods (there are stupid numbers of comments blasted to nothing despite being insightful or informative)

- upvote doesn't distinguish between 'I agree' and 'hey, this is really informative'; the former is mostly meaningless, the latter is useful

- single downmod diminishes what you said and makes it harder to read (on an already low-contrast site). Hardly fair given the ease of 'drive-bys'.

The forum I spend most of my time on has a reason required for the mod - it's not this brainless +/- system that the web is moving towards. You get an idea why people are up/downmodding, and it raises the bar ever so slightly so that it takes actual effort to mod (that is, critique) a comment. The displayed point value is also capped - while the user gets the karma for the mod, it's not displayed beyond a certain cap.

Mostly I see the benefit of this system as stopping mindless up/downvoting - requiring the tiniest bit of effort produces better quality results. Still not perfect, but much, much better.
Wow! But that'd need magnets all over the ground!
Both of your answers ask for more government control. Consider the government is a huge concentration of power, so many will want to corrupt it. Our goal should be to reduce the power of government, thereby reducing corruption.
I think the big difference people are looking past is that when people left myspace for facebook, facebook was clearly better. With Google+ vs. Facebook this is not the case. Facebook is still a much better platform with a better UI, more features, and more mature developer resources. The numbers facebook puts out clearly contrast all the articles saying how they will be replaced etc. They're on track to hit a billion users, period.

The thing is, we are all waiting for room temp superconductors. That paper on the Reddit post seems to have some breakthrough regarding this if I'm not wrong.
Is Facebook getting a heroku error (or is it just me)?
All developed nations are either right at replacement rates (USA) or well below (Japan, former Soviet nations etc). The developing nations (Thailand, Brazil, etc) are approaching replacement quickly. That leaves Africa and the poorer parts of large heterogeneous nations like India.

Some of us demographers think that as we continue to develop, population growth rates will go to under replacement and then sort of bounce around replacement after that due to social reasons.

Pure marketing. "Quantum levitation" is just flux pinning[1] as seen in all "high temperature" superconductors. All you need a chunk of type 2 superconductor, a strong magnet, and some liquid nitrogen. Note the 852 videos on youtube: http://www.google.com/search?q=superconductor+levitation&...

I agree, and this is something I am investigating also. Data Parallel Haskell is an awesome base for something like this, but it is hard to tell if anyone is actually still working on it - and even harder to tell how one would contribute. Especially since there are so many spin off projects like Repa which have some of the functionality but just don't quite make the cut (lack primitives, hard to implement new parallel operations, etc...).

The potential is there, it just needs to be exploited.
I wrote a post that was picked up by HN a while ago about why I left Haskell, so I won't rehash my arguments, but ...

On reflection, I love(d) Haskell, but the tradeoff that created the IO monad was too much for me. After 5 years using Haskell and a couple of years away from it, I've become convinced that the way Haskell isolates IO and state is not the correct solution. I'm not smart enough to know the correct solution, but creating monads, monad transformers and arrows and then providing sugar to get everything to look imperative again feels wrong. Uniqueness Types feel a bit healthier.

Now that I've said that, let me say that I'm most certainly impressed with the work around IO and state in Haskell because it was an amazing bit of intellectual horsepower and is an incredible step. But it doesn't feel like the final step/answer. Unfortunately, I had to get work done for clients and had to step away from Haskell, but I'm excited to see what the community brings forth. It's the most beautiful language on earth.
A system that ships millions of parcels in an almost completely automated way that has only occasional narcotics canines attempting to sniff literal mountains of packages to find one that has an ounce or less of substance that has been vacuum-sealed multiple times.

Then, they have to setup a trap in which the recipient knowingly takes delivery (and there can be no other way than the recipient signing for it, or else it would be entrapment or just mis-shipment, which is just as common) and catch them. All for a person who bought a small packet of drugs.

I think the Feds even consider such a thing a lost cause.

That does not look like liquid nitrogen. It's solid so that tells me it is carbon dioxide.

Logic puzzle: hide and seek with a twist
Bitcoin is something completely new and different. It is like open source software. Until people really understand it, it will be toy for geeks with similar market coverage and price. (or someone find design bug and we can forget about it)

Biggest hurdle when using bitcoins is not it's high/low price, but rather fluctuation.

Fluctuation happens because too many speculate it and not trade with it (well.. currency trading is also trading..) And I would say this is totally expect-able and acceptable.

With time if this technology will prove itself, it become major online payment method. And believe me - work on this project is very active right now. All this investing mumbo-jumbo is just a random noise...

I thought first that this is the same old levitation effect, but apparently it's something new. At least the effect seems to be much stronger.
but you have gone way overboard by comparing Groupon to boo, webvan, and kozmo.

At least those companies had tangible assets to liquidate (boo had inventory, webvan had a distribution network, and Kozmo had a stash of DVD's). Groupon has posted impressive revenue numbers (but still no profit) using an unsustainable model of aggressive spending on advertising and sales team headcount. With growth slowing, increasing backlash from merchants, and questions about their accounting methods, Groupon is on the decline. Maybe TheGlobe.com (http://en.wikipedia.org/wiki/TheGlobe.com) is a more fitting comparison.
There's a whole spectrum of user data with varying value to advertisers. Google already rocked search big time and now they're on to the rest of the online advertising budget.

Ad networks (like me!) use demographic, psychographic, and behavioral data to target most display ad campaigns. I have run campaigns specifically sold as "market to Nigerian immigrants living in America" or "moms 25-35 interested in beauty products." And even when not specifically targeting those audiences, one can often find surprising performance pockets from these audience intersections- good for my performance and useful info to bubble back up to the advertiser.

And... guess who's the current biggest display ad platform?

I've been using Haskell on and off for a few years and have written a few (small) projects in it. Every time I end up turned off of it, though.

First, I don't like how it makes side effects such a PITA. Fact of the matter is, computing is only useful for the side effects. A computation is useless if the result isn't printed to the screen, saved to a file, sent over the network, or used in some other way. So why make side effects so difficult?

Second, the community, or at least a vocal minority, come off as very condescending. If I have to ask a question on IRC I probably already feel dumb, I don't need somebody treating me like a child because I don't understand something.

Even counting for capitolization and numbers and symbols, you get something like:

Groups using simple majority vote cannot hold logically consistent positions, so it is an absolute necessity that those elected for office contradict a majority of the voters.

Specifically, logical conjunction does not hold for voting groups. Imagine three people, X, Y and Z; and some proposition P which is true if A and B are true. Suppose X believes in A, Y believes in B, and Z believes in A and B. So vote on A: does a majority believe in A? Yes, both X and Z do. Does a majority believe in B: Yes, both Y and Z. But does a majority believe in P (which is necessarily true if both A and B are true)? No, only Z believes in P. So conjunction (i.e. the AND operator) does not hold for groups; and without conjunction, consistent logic is impossible.
