One of the things I was really mad about Netflix was the fact they stopped publishing their list of most viewed instant play movies as far as I can tell because customer's were using it too much.

Same with the "New Release" DVD page, which is now hidden but still accessible. Again, customers were using it too much. That one I could somewhat understand as it caused contention for physical DVDs, but the solution seems to be buy more DVDs, don't hide a useful feature.

If Amazon's selection improves, I will be the first to cancel the Netflix subscription and I truly believe Netflix will be in trouble. They just aren't anywhere near as customer focused as Amazon.

I'm meeting with a patent attorney on Thursday to find out the answer to that question. I think it is, but I'm going to find out and hopefully have a provisional patent filed as soon as possible. I agree 100% with you that we have to act fast in order to grab market share and the person I'm dealing with fully agrees with that. What I've built isn't rocket science (though not easy either), it just simply appeals to the market really well. Therefore, moving fast and having this person introduce us to the players in the market is very important, but he's not interested in just commission or even salary. Therefore I'm leaning towards sharing some of the company with him. It seems like a good trade-off to me at this point. Thanks for the comments.
Daniel, The ctrl-click feature is really cool.
I hear you about feature creep. I am struggling with similar issues with what I am working on.
I keep reminding myself Every piece of software I paid for recently is dead simple to use
I'd say just the opposite, at least as far as design 'trends' go.

In the late nineties, every website I worked on had insufferably small type. This was primarily because the web was designed by graphic designers that were new to this web thing. They would often draw a box for someone else to fit the type in. Tables were the dominant method of aligning objects on the page.

Thankfully, we've gotten smarter since. We know that those "words" actually matter. They communicate and are highly scannable, often even better than obscure iconography or visual elements.

Services such as TypeKit http://typekit.com/ should provide everyone with the ability to design beautiful web pages with great typography, and anyone who cares about good typography tends to want that type to actually be read.

Check out virtually any new startup and you'll likely see large bold typefaces, short and concise phrases with a strong visual aesthetic leaning toward a minimalist style.
Sometimes I think this would be a lot easier for everyone if we just hauled out Bayes' theorem and had done with it. If a hypothesis (weighted with your confidence in it) predicts that a set of observations would turn up more evidence for it than you actually find, then that is evidence against that hypothesis, and should cause you to lower your estimate of the probability that the hypothesis is correct. And vice versa.

For example, suppose that I want to explain why my apples have been stolen from my apartment. I live in a hypothetical universe where there are only three possibilities, all of which have roughly the same likelihood, a priori: spontaneous combustion, alien abduction, or theft by a troupe of dastardly harlequins.

If the apples combusted, I would expect to see scorch marks, or perhaps soot stains on the wall nearby. If they were abducted by aliens, I would not expect to see anything, since everyone knows that alien abduction rays leave no signs. Finally, if the vile harlequins made off with my fruit, I would expect to see some signs of their passing -- face-paint on the doorknob, perhaps a fool's cap hastily discarded in a corner.

Now, I inspect my apartment. I find no scorch marks, which is evidence against spontaneous combustion. If my apples had burst into flame, it's technically possible that they could have done so without leaving marks, but unlikely. I find no evidence of alien abduction, which is exactly what I would expect to find, so it does not change my estimate of that hypothesis' likelihood. Finally, I find a scrap of ripped, brightly-colored cloth which appears to have been torn from the outfit of an interloper hastily scurrying away through my pointlessly-large ventilation ducts. My face grows grim as I raise my estimate of the likelihood of my third hypothesis. Harlequins! Foul creatures of the Commedia dell'arte! My apartment has been defiled by their acrobatics and shenanigans! And they stole my darn apples!

So, in the case of spontaneous combustion, absence of evidence was evidence of absence. For alien fruit abduction, absence of evidence wasn't evidence of anything. In the third case, there was evidence above what I would expect from my prior beliefs, so that was evidence for the harlequin hypothesis.
Thanks. Good to know. I'll add the Boxee Box to my super short list.

Right, but it's extremely difficult to get concurrency right at the application level. Anything that works usually works by chance, and changing the hardware that a multithreaded program runs on is a great way to find out how you fucked up the implementation.

Right now, it's likely that a lot of bugs are not showing themselves regularly, so nobody has bothered running any diagnostic tools (Helgrind, etc.)
Agree with the above. I have a fair amount of experience with traffic court- you did not get off because of your GPS; it was because of the officer's answers to your questions. Good job asking, though.

The #1 tip for any court situation like this is the question the officer about events on the day it happened. By default the officer's word (and/or his radar gun) is worth more than your own, but if you can get him to say ANYTHING that calls into question his recollection of events, then his credibility is reduced. Incidentally this is also why most cops take great notes.

You should restart, it's an underexploited niche. The Zenonia games on the iOS have been wildly successful despite their formulaic predictability and underwhelming exploitation of the device's capabilities, simply because they're the only thing available in an overhead-view adventure semi-rpg.

>iOS would be effectively identical to Android and no one would complain about this 30% because they'd just hop over to Android without a second thought.

Your point is not very clear here. Are you claiming that Android cannot be run on the iPhone (technology wise), or that iOS provides an API whereas Android does not? Both don't seem to be the case.

>In return, Apple believes they can charge fees for various methods in which a developer may choose to use the wide range of features Apple has created in their iOS eco-system.

My contention is that if Apple charges for the application usage revenue share for using iOS, then its fine. Also if Apple dictates that if an App is free to install for a customer (in which case it gets zero revenue from end user for iOS services), then it can charge a share of the subscription revenue. However, Apple dictates that it be paid 30% of the end user subscription revenue regardless of any distinction of whether the revenue is from the application, or for its content. (Yes there is a fine distinction between the two. To Apples credit some of these application are distributed for very low cost (near free), in which case Apples revenue share is disproportionate. But then Apple also charges an annual developer license fee!

>If Readability is "allowed" to charge the content owner 30% to give me that special Readability access, why can Apple "not" charge the developer 30% to give them access to that special Apple eco-system?

Of course Apple can, and it does charge developer 30% of Application revenue. It also charges $100/year per developer for its API. But what is not fair is that it also demands an additional 30% of subscription revenue. What has Apple done additional to providing an iOS environment and API (the first 30% cut) to warrant a subsequent subscription revenue share (blood sucking second 30% cut)?

>My entire point would be moot if Apple required 30% of all revenue from Readability regardless of whether the subscription originated from within the iOS app or from Readability's website - but Apple has not done that

- No link allowed to App publishers website to subscribe from there.

- Not allowed to use items which were subscribed outside iStore, unless it is also available in iStore.

These points reek of blood sucking greed. May Apples developers leave in droves to Android, and beat some sense into shitty Managers unfairly monopolizing Application development on its iOS platform.

I feel it's too harsh to downvote you (so I didn't), but you've pretty much admitted that you don't have enough information to speculate - perhaps you shouldn't. It's not about system software supporting threads; it's about user code not being thread-safe in the presence of hardware parallelism. There are some multi-threading bugs that never show up without it.

O'Reilly sells DRM-free ebooks through their store, so they're unaffected. You load the ebooks onto the iPad using the usual transfer methods for media.

It's one of the nice side-effects of selling DRM-free books: they don't need an app that has the DRM baked-in -- you can use iBooks or any third-party reader.
Lots of useful general advice about building products. Cutting features is definitely the hardest part of his recommendations. Especially when a product is small and easy to enhance, it's tempting to add just one more feature. You just need to keep reminding yourself that getting it out the door will focus your efforts on what people actually want, and you'll know for sure whether that feature is worth building.
The top answer on Reddit was not helpful to me, and seemed tautological even in the face of its length.

A downside to this approach is not having an easy way to purchase books without a computer. iBooks has a great checkout experience and the only way O'Reilly could have something similar is by coughing up 30%. Tech savvy users can figure installing something like GoodReader and then downloading the PDF in MobileSafari and sending it over to GoodReader, but it's a UX nightmare. O'Reilly at least has technical users, other publishers are even more screwed if they want to go non-DRM.
I haven't used it in the field yet, but I just received my Square device. Great hardware and software for something I thought was vaporware.

Well, we've been through this before.. but I still don't understand, who cares about smaller bid/ask spreads for their own sake? Say HFT was unilaterally banned (which would be ridiculous and excessive), and now bid/ask spreads will naturally spread apart for maybe MINUTES at a time before someone notices and arbs the difference.. how are we worse off?

My major beef here isn't people making money for doing stuff I think is useless.. I think Us Weekly and People Magazine are useless but I don't begrudge the editors their paychecks. My beef is how much talent is being sucked up into a game that doesn't seem to provide any outside benefit. If all of those people were building actual products and services that people paid for (as opposed to basically hacking the finance system for profit), I feel like the nation and world would be a lot better off for it. In short, I think it's a market failure that they can make so much money without actually creating anything.

Run it until you know there are no major snafus. I.e., system doesn't auto-purge your DB, assimilate all your users and nuke the planet.

Once things are stable, start scaling the beta up to a reasonable number of users. I.e., stress test, in increments. Once you meet a pre-set milestone, set it loose.

Goodluck!
What surprised me was that they were using 15k rpm drives over SSD's for database lookups. Any idea why?
Yeah, I think that section of the article could be improved.

If I were facing their problem (where they had already chosen to use URL fragments for navigation but also didn't want to miss out on crawlability) I would use a different approach than maintaining a separate set of static pages.

Instead of static pages, I would create a single servlet/cgi that would handle the URLs to these pages. The content for each URL could be created on-the-fly on the server side using some server-side browser (like HtmlUnit, Cobra or Crowbar...) to receive the requests, translate the URL into the fragment-format, run your actual javascript application (which is already written to handle such fragments) and capture the resulting DOM to send back to the actual browser that arrived via the Google search. Of course the HTML could be persisted so that this process would only need to happen once per URL. The benefit of doing it this way would be that when you deployed changes you could simply invalidate the HTML cache and let your system build them again automatically.

But it would probably be better to avoid the problem entirely by thinking about SEO needs up front.

I agree with you that people are really bad at concurrency, but I disagree that it's that hard once you get used to it.

Once you deal with one large deep difficult highly concurrent project, you get used to the idea that when there are threads and mutexes involved you have to think REALLY HARD about how it should work, and you can't rely on just trying something and testing it like you can with normal code. And if you do that, you can get threads to work pretty reliably, not just by chance.

Exactly! This high level model doesn’t draw on any quantum specific phenomena and is in many ways comparable to other stochastic dynamical models that have been developed to explain the non-Arrhenius behavior of protein folding using classical Langevin theory.

To argue for the inclusion of quantum theory in explaining protein dynamics is to assert that proteins undergo classically forbidden conformational transitions. The authors of the paper have provided no evidence for such transitions nor even hypothesized about how such transitions could arise. Their only argument against a classical description of protein folding is the inability of molecular dynamics simulations to model the folding-kinetics of some proteins. Seeing as molecular dynamics force fields only provide a rough and approximate description of the forces between atoms within a protein it should be no surprise these methods can’t accurately model the intricate conformational transitions in protein folding.

Show HN: Get links pulled from Twitter favorites into Instapaper
@glasner and I shipped a product today, http://www.tweetgrabber.com, that allows anyone with an Instapaper account to receive full-length articles that were favorited by anyone with a public Twitter account. You can now essentially crowdsource your Instapaper reading to those you trust by following their favorites. We use Twitter's streaming API to send articles straight to your Instapaper. You can follow your own favorites (single player mode) or follow anyone else's (multiplayer mode), forming a graph of curated real-time news.
If you are intent on following through and selling, you should come up with a sliding scale. Maybe 1-2% for the minimum of what you'd sell it for, and a bigger percentage (10%) of the difference if he sells it for more.

I don't know if that is standard practice, but it seems reasonable to me.

I buy that, but I guess to me that is what the slogan is supposed to imply, but I do agree it's not always taken that way. That is: merely not finding evidence tells you nothing. However, not finding evidence, when you have a prediction of what evidence should be found, may be evidence against. So you need two things there: 1) absence of evidence; and 2) a prediction of what evidence there should've been. If all you have is #1 by itself, you have no evidence of anything. Hence, absence of evidence (without more) isn't evidence of absence.

Maybe I'm in the wrong debates, but most of the times when I see the slogan applied, the person doesn't have the second part. For example, a common elementary error is to conclude that variables are uncorrelated because you calculated their correlation in your data set and it was not significant. Failure to find a correlation in a very large population study that's large enough that it should have found one, can be evidence of no correlation (or no large correlation, at least), but you have to do a separate analysis for that.
People hate this word, but I will say it anyway, you need to have a brand of your own. Create a presence online (via Linkedin, Github, your own blog etc) with a distinct identity that projects your capabilities. Absent this, people will do the easy thing, which is, generalizing and stereotyping you as just another developer from India or whatever country you come from.

I really enjoyed this article, and it definitely took a different bent than I expected, which I'm starting to think will be a hallmark of Mr. Altucher's writing.

His excellent advice boils down to the following:

Have personal contact with every client or contact your boss deals with. This puts your name and face out there, and makes it easier if you need to work with them directly in your own business in the future.

Develop and hone skills that will be valuable outside your current job. Spend some time each day learning something new, even if it's not directly important to your current job. You don't want to stagnate, and who knows what skills might be valuable in the future?

Be more productive than you're used to. Most people only work a couple of hours each day, and spend the rest of the time web-surfing, emailing, chit-chatting, etc. Put in a solid 4 hours of work every day and you'll shine above your peers. Then spend the other 4 hours being productive and learning new skills or practicing existing ones.

He has two other bits of advice, but I don't see how they're "exploitive". Always give your boss credit for everything. I'm not sure what this gets you. And send out your resume to gauge your current worth in the market. That's an excellent idea, but I'm not sure how that's exploitive.
