As much as I like Apple and ebooks, it sickens me that they want to charge more than $10 for best selling ebooks. It is an electronic file. I am willing to pay more than $10 for a physical paper book I can hold in my hand, but I can't see spending more than $2-$3 for an ebook. And so I rarely buy ebooks, even though I want to, because I can't see the economics behind doing so.

If ebooks are going to be just expensive as paper books then I'm going to buy paper books. Apple and the ebook publishers are just shooting themselves in the foot.

That is the best thing about HN, if people do not like your link it just dies down and you cannot share it again.
I, too, use a nodejs server to control multiple phantomjs processes. There's a patch that lets your script read from stdin -- last weekend I modified it to support my platform's preferred line ending.

I don't understand why they aren't selling ebooks for the same price as printed books, minus the production costs. That would be fair.

As as side project I helped a friend publish a small book on Amazon for the Kindle. At the time we looked into doing the iBooks Store, but it was not yet open to self publishing.

Apple's requirements for pricing were as follows:

1. You could set whatever price you wanted. (e.g.: Apple doesn't fix the price at anything specific)
2. If you sell the book electronically elsewhere, you cannot sell it on iBooks Store for more than the price you sell elsewhere.
3. Apple gives you %70 of the sales.

I don't see how this is price fixing, nor is it trying to keep the prices higher. You can sell on the kindle for the same amount as the iBooks Store.

Amazon's terms:
1. You can set the price as you like.
2. You get a variable cut of the sales (sometimes it is %30 to you, %70 to amazon.)
3. Amazon can change the price if they want and sell your book for less, and pay you less.

So, yes, it is true that Amazon can run specials where they sell your book for $0.99 to drive traffic to the store, and when they do it, they do it at your expense.

I believe the facts don't support an allegation of price fixing.

As to the idea that Apple was "trying to run the kindle out of business", that's an allegation that is true of every instance of competition. If someone prices an android tablet that is competitive with the iPad feature-wise at half the iPad's price, that's "trying to run the iPad out of business" as well. It is what you're doing when you compete for sales, you want all of them to go to you and none to your competitor.
Using RESTful APIs
I wrote a basic introduction to understanding HTTP and using RESTful APIs for people who are unsure how everything fits together. The format is not that of a research paper and is instead intended to serve as a basic primer for new programmers and startups interested in breaking into the world of RESTful APIs. Hope this is helpful and I look forward to corrections, criticisms, and feedback. Happy hacking.
Good point. I guess in the past I have spun up a micro instance to run it, so I didn't have to run my S3 operations using one of my main production servers, and hence I didn't run into any problems with its unthrottled speed.

Wouldn't talking more, much like writing more, help that skill?

Yes and no.

I think "talking more", in the sense of finding more occasions to speak: more meetings, more conferences, etc, would be helpful.

However, I don't think using more words during each of those occasions would improve your verbal communication skills.
Probably none, even though i didn't state my opinion on the subject itself.

Measuring long-time-effects is hard. You probably could convince me with a well-done study that violence in games has a short-term effect on aggression. Like letting people play and provoke them afterwards, measuring the different reactions when playing prior an ego-shooter or Sims.

But long-term-effect? Just a have a look in the study. Using factors like the VGV-general measure fails to convince me that they didn't just discovered that violent people like violent games, or that people of the working-class or lower prefer to play (and are generally more aggressive) and so on.

I'm looking at both Scala and Clojure right now. I'm a .Net guy these days, looked hard at (and fell partially in love with) F#, but - I need to broaden my field.

And - I'd like to see if I can (ab)use those languages to improve my experiences with Android.

So far I'm heavily leaning towards Scala. The documentation seems to make more sense to me. It seems powerful to ~no end~. This post now, while being not totally impressed about all things Clojure, ends with an unqualified 'still more usable than Scala', which threw me off.

More data points, please? If the writer is true and makes sense: What's the reason for this comment? Convert me. :)
I agree it would be fair. I don't agree that it is unethical. But I think it is counter productive. Attempts to price electronic items higher than the physical ones will only result in those items being pirated. They have not yet learned this lesson because they clearly think that the higher price will lead to more sales of the printed items.

I guess every industry needs to learn this lesson.

On the upside, the more they get addicted to the revenue from the electronic versions, the more strategic it will become, and once it is sufficiently strategic to them-- rather than the experiment I think they see it as now-- they will start having to seriously compete.

This will change the market dramatically, and most effectively.

The alternative- forcing their prices to be lower will only result in them removing availability (e.g. they'll stop publishing ebooks.)
> Virtual functions are "costly" too, but C++ has them and it's considered poor form to not declare your destructor virtual.

It's a bit more subtle than that: a virtual destructor is only required when the class, or its base classes, already have another virtual function (and it's only really needed if another class inherits from it. hmm.) At that point, a virtual destructor doesn't add any more cost over and above the virtual function that's already defined.
This reminded me of a quote, "Better to remain silent and be thought a fool than to speak out and remove all doubt." It's attributed to Abraham Lincoln (e.g. in the Yale Book of Quotations).

It's a humorous twist on a Bible verse: "Even a fool, when he holdeth his peace, is counted wise: [and] he that shutteth his lips [is esteemed] a man of understanding." (King James Bible, Proverbs 17:28)

Contrary to popular believe, the scientific value of the experiment was lost. It's only real value today in the field is as an example of how not to run an experiment.
Apple would rather charge you $0.99 for every ebook. Just like they'd rather charge only $0.99 for a single, and $0.99 per TV show and $0.99 for a movie rental. Where they have enough pricing power, they are able to achieve this (they held the line on the $0.99 single for a long time.) Where they aren't they aren't.

Unlike Amazon, Apple is not in the business of selling books. Apple is in the business of selling iPads. Apple doesn't dictate prices - they let you set whatever price you want - because Apple realizes that central planning doesn't work. (Apple' can't know what the right price for frankenstein should be, and doesn't even try, while Amazon, as a retailer, does have pricing experts. Apple just want's %30, and for the market to be as robust and vibrant as it can be.)

Amazon would cut prices against the publishers desires, and the publishers would get the lower revenue. Amazon did this to drive up popularity of the kindle. Apple doesn't believe in operating this way, and has a consistent policy- you set the price.

I believe Apple's approach is superior because more people will sign up and there will be more availability of books. (and the iBook Store is probably much large now than the kindle store was at the same number of quarters after launch.)

I don't know much about Amazon's balance sheet, but I do know that, while Apple does make money from iTunes, it is not strategic money. It is money that helps fund data centers, and stuff like that. Apple's not in the media business, it is in the devices business, and it operates a media business only to generate demand for devices. %30 is meant to show a slight profit, not to boost the bottom line.
Is that a global number or just the US? If global, is it possible to segment to US?
The FAQ mentions an article from 2003. I don't know these people, don't know if this role is part of their academic career like suggested in a comment above, but even being of that opinion such a long time suggests a bias when starting a new study.
ngrep was news to me. I think I've heard of it once before, recently, but didn't really realize what it was. Having not tried it, it sounds like a really nice option when something like Wireshark or Ethereal would be overkill or just too much effort to bother with.
The linked article has nothing to do with self-publishing and everything to do with books from large publishers:

> The complaint claims that the five publishing houses forced Amazon to abandon its discount pricing and adhere to a new agency model, in which publishers set prices and extinguished competition so that retailers such as Amazon could no longer offer lower prices for e-books.

Amazon's discount specials also are not relevant to the price-fixing claim.
The second part of the article, titled "Why I tried Clojure then stopped" shows a very shallow understanding of the language. His point is that Clojure heavily uses vectors which aren't efficient when the collection changes size frequently. Clojure does in fact heavily use vector literals in code, but those aren't large enough for their performance characteristics to matter under most circumstances. The use of vectors over lists is to differentiate things that get executed from things that don't; lists are code and vectors are data.

I ran some tests with a function that did nothing but recur/drop on a sequence. There was no speed difference between a vector, a LazySeq (previously evaluated), a PersistentVector and a PersistentList with a million elements. I tried it with ten million and it was 400 times slower with both a LazySeq and a PersistentVector. Attempting to make a PersistentList from the 10M element LazySeq with 'into' resulted in running out of heap space. I did not try again with more heap space allocated.
uff, it's controversial territory... scala is certainly closer to f# than clojure. that could be good - easier to learn - or bad - you learn less (i would strongly encourage learning one lisp, and working through "on lisp" to grok macros, if you haven't done so yet). my problem with scala is that i found it too complicated. i was really frustrated and disappointed with it, and that was exacerbated by my hope that it was the future (i thought it would be haskell for java programmers - and it is, in a way, but it achieves it through brute force rather than elegance, imho). but that was just me, and some time ago (when the language was changing more rapidly) - it may be better now, or for others...
That would be great. Thanks so much. my email is radio4theages.tech@gmail.com
One thing I saw missing from all the comments and cost breakdowns is how I see the major component of the iPhone: software. The comments on the Economist seemed to be along the lines of: "see how stupid the American company is... outsourcing everything to Asian companies who are going to steal their ideas and eat their lunch".

The second largest component? Industrial design. Another factor not to be discounted. And Apple has some of the best in the world.
Printing cost of a paper book is only $3-4, so even eliminating the cost of printing, ebooks would still be expensive. I suspect most of the cost of books goes to marketing and promotion, not printing and binding.

I am referencing the distinct group of people who appear to be defending Sam Odio. What seems to be going on is there are a few members of society, Sam Odio seemingly included, who believe that since Sam Odio was "participating" in the experiment that we should not criticise his actions. This shows an aborted understanding of right and wrong, for it is very possible for Sam Odio to both have participated in the experiment (I object to the suggestion that he did, but lets ignore my objection for now) and for Sam Odio to have acted in a morally reprehensible fashion deserving of a great deal of criticism. The more I think about it now this morning, the more I realize that this sounds like a case of aspergers.
an economy of words
Self publishing is irrelevant to my point. The terms I mentioned are the terms both companies offered to everybody. Apple offered better terms, and specifically included in those terms that publishers couldn't jack up the prices compared to the price elsewhere.

The only reason Amazon offered "lower prices" in the past is because they ran discount specials. Amazon also allowed publishers to set the price on the books, except when Amazon would run a lower price.

Further, the complaint is to price fixing, and the reality is, both before and after the iBook Store came into being, neither company engaged in price fixing.

I could see that working for very standardized courses with objective tests, like intro calc, but it'd be more problematic in higher-level courses. There isn't usually 100% consensus on how to do many things, like what constitutes a good project and what things are most important in a write-up (and the higher-level you get, the more sharp disagreements between professors get). So students and professors, fairly reasonably, bridge the gap by communicating about shared expectations. If then a third party grades it, they might be grading in a way that isn't actually consistent with what the professor asked the students to do, and with what he/she led them to believe would carry the most weight in grading.

An analogy might be going back and forth with a client on contract work, delivering a result you're pretty sure they're happy with, but then having it assessed by someone other than the client, who didn't participate in the previous discussions. It's a sort of multiple-bosses problem, which can make it harder to focus and feel confident that you know what's being asked of you.
The allegations stem from the agency model that was forced on Amazon by the big six publishers when the iPad launched. Previous to that model, Amazon treated eBooks like they did everything else -- they'd buy them at a wholesale price and then sell them at whatever price they wanted. That included, to my understanding, selling them at a loss so they could sell more Kindle hardware.

Under the agency model, the publisher sets the retail price instead of the wholesale price. So Amazon now has to sell it at that price. This is probably different than the deal you got with Amazon since you don't have the leverage that the big six have.

The agency model also includes other stipulations to protect the traditional publishing model. One example is that many eBooks don't launch for several weeks after the hard cover books. My understanding from listening to Robb Wolf and Tim Ferris talk about their recent book launches is this helps the NY Times Best Seller rating in some way.

As a consumer, I use Amazon for their discounted prices. Recently when I wanted a book, I could pay $49.99 at the local B&N or $32.95 at Amazon plus $3.99 for one-day shipping. However, had I wanted to get the same book in digital format, my options were $39.99 at Amazon or $39.99 at Barnes & Noble.
