Im not sold on node. Why should i ristrict myself? There are async librarys in lots of languages you can use them if you have a problem that suits the async modle but you can use other models to if they are better.

The other thing with node is that it is single threaded do do multicore you have to use process witch are slow in communicating. This could work now because we often only use quadcores but in the next years we will have many many more. Is it a solution to start node up for say 16, 80 or 1000 cores?

Im not ranting on node I hear it works fine for some stuff but the benchmarks that got everybody so exited in the beginning was not really that practical.

If I write a low level it might be fast because it maps to the C stuff good but if I write a big application with lots of layers of JS will it still be fast? (I know that V8 is getting better but it there jet for big server applications?).

Hope somebody can talks about this.

Nicely done, I like the minimalistic/simple look.

I'm not sure who the target audience is: if I'm living somewhere, I probably know about the local news sources, and if I'm in a shorter visit, I probably don't care (or if it's in a foreign country, I might not know the language).

One suggestion: add the posibility to suggest modification of the source data. Eg. a few of my local sources have missing diacritics. I'd love to contribute that small fix back, but can't.

This way you can also allow your readers to notify you of bad/broken links (ok, you can handle that if you're going to get the rss feeds) or anything else that may happen over time, so you don't need to worry about it, just look it up if reported.

Also, thank you for not requiring my exact location to be able to suggest (correctly) where I am. I'm annoyed by how many sites litely want to know my location just so they can "improve my browsing experience".

I think you are missing the point here.

Learning math is not like learning programming. Math has a quantitative evaluation process.

The kind of scenarios you are talking about both have a quantitative and a qualitative evaluation process.

I.e. you can be creative in your programming and the "answers" but not so much in math.

Also I don't think Kahn Academy is in any opposition to Seymore Paperts "Mindstorms". In fact you could imagine the videos being used to teach children to get started before they go on to hack together their little programs.

What they have done is for the first time made a system that quantifies the learning process so that it benefits the student rather than the school.

Pretty significant if you ask me.
Everything Kahn says seems to indicate that he doesn't believe in simply "watching a video and drilling on some problem set."
It's more like "Everyone is talking less about Rails" - the only new kid in Rails block is Haml/Sass and Rails is obviously stagnating compared to the hype it had couple or more years ago. Ruby/RoR is more about evolution now: Rubinius, JRuby going for stability, SalesForce adopts Heroku as one of it's development platforms - look, even one of Big 4(DTT) hires RoR-consultants now.

JavaScript on the other hand is booming both on client (SproutCore, Backbone, Cappuccino, CoffeeScript, GWT) and on server (Node). JS is just more "hackish" today - browsers are evolving day-by-day, taking more and more functionality from server - RoR isn't key to success anymore, it has become just another alternative for your REST backend.
It's possible that the iPad GPU doesn't support all the operations Handbrake encodes and has to have the CPU decode them (resulting in higher CPU and increased power usage), whereas the media in the iTunes Store might have been encoded with only the operations supported by the GPU. This is just a theory, however it's certainly plausible.
It is kind of working out. People making minimum wage have things that were sci-fi when I was a kid, better than the most expensive attempts the rich made to try to buy their way in early back in the day.

Global communicators that fit in the pocket, 40 inch high definition flat panel view screens, game systems with unimaginable processing power and graphics. Most people can't even sign up for basic cable without getting a time shifting miracle-machine or a basic cell phone account without being handed a damn tri-corder.

No argument that inequality of wealth is growing rapidly, but its good to remember that total wealth is growing too and even the poorest are benefiting.

What we really need to do is pull all of the parasites out of our health-care services and allow this magic to happen down there as well before the have-nots figure out it doesn't matter whats on your giant TV if you can't afford those patented, insurance inflated, heart pills and decide maybe its time once again to dust off the guillotines for another go at the rich.
When you say early code, do you mean code that was replaced or just older code?
Some folks on this thread have suggested that you open your own merchant account. FWIW, you're likely to face the same problems with that route if the underwriting department takes a good look at your business model. If you're selling "experiences", it's too hard to demonstrate whether your clients did or did not receive the alleged service. You're likely going to open yourself up to a huge risk of chargebacks -- remember, you're now vouching for the performance of each and every one of your "experience vendors". A chargeback rate of just a few percent would eat up all of your profits, and get your merchant account canceled to boot.

It would also be incredibly easy for me to launder money or commit fraud with your system -- I could just set up a fake experience, like navel gazing, at $100 per, and buy up unlimited sessions with stolen credit cards, or give myself a massive cash advance at purchase interest rates, with a small mark-up. Maybe I'm missing it, but if your system doesn't include some way to reserve the time for the "experience", then there's really no way to ensure that your vendors are not double- or triple-booking their time.

To summarize, the financial risks of your business model run far beyond PayPal. If you can come up with ways to hedge against these risks, you might even be able to convince PayPal to take you on (though I wouldn't count on it).

Older code, some (but not all) of which was replaced.
although 3.times is probably harder since all ruby methods take an implicit block as last parameter. The prettiest code you could do in node would be 3.times(function(){/code/})

It would be nice if js could rid of the keyword 'function' -- maybe make it a bit shorter like in coffeescript.
I like to original comments page more. The font after applying the extension is not contrasty enough, and the gap between the lines is too big. It's definitely not more readable.

Generally, too much free space - I personally prefer tighter desing with less scrolling. But still good try, it would be great if you offered some customizations.

For me, the presentation is just better. There's something about 10-12 minute lessons, and obviously the thought that goes into distilling it to that size, that makes it digestible. (I'm really curious how much time goes into making one 10 minute lesson.) It sticks.

One caveat: I've been exposed to this material before in other contexts, so it's more like a phenomenal refresher. I can't know if this is a better way to teach from scratch. But, frankly, it's been long enough, or I was just that bad at it the first time, that it sometimes feels like I never learned it in the first place. This gives me some degree of confidence that it's at least one right way.

Ask HN - Should I buy an iPad 2?
Well, come March 11th and we see the release of iPad 2, the next generation iPad.

I don't own an iPad, but I have used one and really liked it. It is gonna setback me by a few hundred quids, but should I go for it?

To add, I watch a lots of videos - films and serials. And read at least a book a month.
No, but that assumes I visit every link. I only end up clicking on 10-20% of them.

I suppose I could simply find a browser extension t visit all the links on the site, automatically, but that doesn't seem right if I'm not going to look at the articles.
There were only a handful of Paypal founders and virtually all were extremely successful. There were 3,021 pre-IPO Google employees [1]. Seems like an unfair comparison.

Hmm, this isn't a "Paypal horror story". This is a case of Paypal getting around to due diligence on a new customer and realising that they are not in line with the terms and conditions.

You are accepting payments on behalf of other merchants (those offering travel experiences) and that brings risk. Unfortunately this is not an issue limited only to Paypal, many other payment operators will reject you for the same reason; the fraud liability is just all over the place with such systems and they won't want to take the risk.

It sucks, but there you go.

If you are really looking at 10's of Millions in revenue over the next few years.... go to your bank and work something out with them, although it might be initially expensive while the offset the risk.
Wow, the words "pathetic", "desperate", and "classless" come to mind.
sure, just to experience what a fundamentally new and important class of device feels like. You may even be inspired to develop something that takes advantage of what iPad can do (that other devices can't easily do).

You have the typicall overthinking problem. You should just start to write useful functions and then when you really see a need for something like multiple dispatch you have it at hand to solve your problem.

Congratulations. It is an unintuitive solution to a persistent problem. Is it serendipity that you were doing PPC and making music at the same time? Most broke artists wouldn't have thought about spending money this way to get exposure, but this can really solve a very fundamental problem.

It is probably true that the minimum wage is not a binding price floor in rich white suburbs.

Well, first off the 2006 LJ issue predates the implementation of HttpOnly cookies I think. They're a fairly recent invention.

HttpOnly doesn't really fix the issue though. It prevents evil js from straight-out stealing the cookie, but it can still make HTTP requests that will include the cookies. Therefore the script could still do bad things the user's behalf (add or remove friends, scrape private data, post spam, etc...)

The LJ story is just an example of a general lesson: if you can put user-generated content in a different domain (i.e. browser security context) than your authentication-critical cookies you are in a better position. That way any javascript leakage at evil-user.yourdomain.com can't harm your users any more than if they were viewing it at www.evil-users-domain.com.
Yeah, I'm using it right now. A thicker font would be wonderful.
"To be second to the Soviet Union in establishing an outpost on the moon would be disastrous to our nation's prestige and in turn to our democratic philosophy."

Though it is probably easier to see now than it was during the cold war, that claim (especially the last part) is flawed logic.

Although countries may need to use military force for self-preservation, functional ideologies do not need to be propped up by being first, more prestigious, or impressive.
It's ``ha ha only serious'', actually. Whimsical style and solid analysis of algorithms you can actually use to schedule your procrastination & work better.

What makes you think it is "wrong"? Simply because it isn't the case now? I believe it doesn't have to be this way. Who would have predicted large scale democracy before the French Revolution?

Also, don't define "creative potential" as "high IQ". IQ is just an arbitrary measure which correlates with intelligence (and even that is controversial).
I don't have a clever reason, other than I want to get one, so I think you should too.

GoDaddy's SuperBowl Ad and Charlie Sheen's Tweet  - Impact Comparison
I think you're right regarding Khan Academy not necessarily being in opposition to Papert's Constructionism. But I think Papert would argue that learning math is very much like learning programming. In fact, he created the Logo programming language as some sort of "mathland" where learning math would be like learning French in France ( http://www.wired.com/geekdad/2007/03/the_origins_of_/, http://j.mp/h6BiOC)

Real mathematicians have often lamented on the approach to mathematics that schools have taken. For example, this essay titled "A Mathematicians Lament" starts like this:
"A musician wakes from a terrible nightmare. In his dream he finds himself in a society where music education has been made mandatory. [...] Since musicians are known to set down their ideas in the form of sheet music, these curious black dots and lines must constitute the 'language of music.' It is imperative that students become fluent in this language if they are to attain any degree of musical competence; indeed, it would be ludicrous to expect a child to sing a song or play an instrument without having a thorough grounding in music notation and theory. Playing and listening to music, let alone composing an original piece, are considered very advanced topics and are generally put off until college, and more often graduate school. As for the primary and secondary schools, their mission is to train students to use this language— to jiggle symbols around according to a fixed set of rules: 'Music class is where we take out our staff paper, our teacher puts some notes on the board, and we copy them or transpose them into a different key. We have to make sure to get the clefs and key signatures right, and our teacher is very picky about making sure we fill in our quarter-notes completely. One time we had a chromatic scale problem and I did it right, but the teacher gave me no credit because I had the stems pointing the wrong way.'"

You're assigning your success to disciplined sleeping habits which seems very strange.

I would ascribe your success to proper nutrition, proper mnemonics, adequate sleep, and lots of studying.

Getting enough sleep (and not too much) is important but what is the advantage of keeping it within those tight boundaries? The natural human sleep cycle is often running on non-24 hour cycles and the science I've seen indicates that if you CAN work on these cycles it enhances memory, cognition and creativity.

I don't understand why you give so much credit to your rigid sleep schedule, especially because all the science I've seen indicates that what is important is getting adequate sleep and then studying properly, not sleeping at particular times.

This is my first time posting here. The article is sponsored by Rackspace and I do not know any other companies which are using Rackspace and Node.js. I'm interested in this area of discussion and would like to know if anyone else is using the Rackspace cloud and Node.js. I'd also be interested in knowing other ways Node.js can be setup to work with Rackspace servers. Any additional information would be much appreciated, thank you.
I'm not sure what you mean here exactly, but I think you are implying that rich white suburbs don't abide by the minimum wage when hiring? Alternatively you might be saying that everyone in a rich white suburb manages to make more than the minimum wage. Either way it reeks of ad hominem by playing on the accepted racism of white people as heartless and trouble-free.

Regardless, saying people work below the minimum wage is irrelevant to my point that the minimum wage is sufficiently low that it does not deter people from hiring unskilled workers.
You know something why don't you take the core of your service (the ability to handle large datasets) and just make something that's essentially Quantitative Analysis for dummies. Or a HFT fund for dummies?

There are tons of, um for the lack of a better word, amateur would be stock brokers who like to play the market, but they really don't have the knowledge neither the access to tools like this. So, if you offer this to them then the sky is the limit to what you can make. Essentially leverage all of your abilities to help amateurs to professionals work in the cloud and handle datasets.

Moreover, replace python by your own query language that has an english like syntax that will appeal to such people.

Ask HN: If you were just starting development, which platform would you pick?
Web, iPhone, Mac, iPad, Android, Android tablets, WP7, etc.

Yeah, I agree that good people can be successful with any tools, but I also think that good people with decent tools are even more successful. And good people will quickly see what is wrong and with what tools they can be expressive enough. And I think modern languages generally fall close to each other.

If you go into a significant company with any significant developer culture, they would have their own libraries and tools, which you would use because then you can deliver. So when those are written in f.ex. Python you would use it. Sometimes this also means that you use e.g. Eclipse though it has numerous problems because at least those problems are shared with most other developers and you don't have to fight them alone.

Google undoubtedly had great programmers pre-MapReduce et al. so they already had great stuff to use.

Yes, Java is not elevated to great language status by the wealth of libraries. It gets the job done and it is possible to be productive with it, but many times you have to fight it. The language drags the libraries down in this case. In most other modern languages, I would say the libraries are what matters.

Racket has a decent repository (PLaneT) for libraries and easy ways to wrap C libraries.
Interesting figure!

The low gravity is a big advantage though. It is very easy to get things into space from the moon.

So if you can construct things on the moon, you have an advantage in space. It also makes it easy to hurl things into space for more destructive reasons.
