I did not make a claim that users don't buy these things: I showed the profit margin from, for example, an app, and demonstrated that each user would need to buy 1000 of them per iPhone.

Almost everyone with an iPhone uses apps, and a very large number even use paid ones, but that doesn't mean it is an important figure in Apple's financials.

So yes: I agree that the fact that you can do all of those things with the iPhone is /why/ people get iPhones (and in fact stated something similar in my earlier comment), but the money actually comes from the sale of the hardware: not the "services, music, and videos".

That said, I think the balance shifts drastically with the AppleTV: everyone I know with an AppleTV rents tons of stuff from iTunes due to the increased ease; and I can see the argument for iPods as well: if you are an iPod-user, you have bought into a specific vision of "music on the go".

But seriously: take survey of everyone you know who has an iPhone, and ask the question "where is the margin"; given your response, I think you will be surprised of the answer. And really: this isn't a ding against Apple... it is to Apple's credit that they seem to understand "where the money is", while all of their competitors fight over scraps.
I think its time to de-couple ourselves from providers like Google, facebook, twitter. I for one am not very comfortable in getting into a 1984 situation!
I'm concerned what will happen when they run out of wells to drill. The area has seen an oil boom before, but nothing like this. 5 years ago the town of Stanley had about 1,500 residents. Today it has over 10,000, many of those in temporary housing. Williston has put a moratorium on any further expansion because they simply can't handle any more people.

There's a lot of jobs and money around, but it's a mixed blessing for sure. When the oil dries up, and it will someday, a lot of these towns are going to get hit really hard.
This line of thinking has been thoroughly discredited. Many of the most successful companies today had founders that took money off the table early.

If they didn't believe in the company they could just sell it today for $500 million (or whatever) and put $50 million in their pockets instead of $5 million.
Wow, that's very cool. Your search is indeed very fast, it feels nearly instant!
Haha! This is the sort of stuff we should see more often on HN. I'd just like to say that I love the tagline -- "because CSS gradients are just not there yet". Just imagine the poor sods who wrote the gradient renderer in the popular browsers. To me, the gradients generated by the site do look really good, and if these are beyond CSS3, then CSS3 should be expanded.
The blog post is content-free, so instead of wasting thirty seconds reading it, I'd suggest HN members for whom the title is interesting instead grab a copy of Arnold Bennett's _How to Live on 24 Hours a Day_. Written in 1910, it is one of the first self-help books, it is firmly in the public domain, and is a lovely "meta" companion to Getting Things Done.
Here's what probably happened:

1) Chamath talked with airbnb, and he felt that he was scoffed or otherwise disregarded

2) Chamath talked with Reid Hoffman, and both concur on the matter

3) Reid and others talk with AirBNB but the airbnb people stuck to their guns

4) Chamath believes that he is right in his view, and hopes that by going to the public, others (i.e. PG) will pressure airbnb to reconsider (especially with the groupon comparison)

Now, I don't know the airbnb founders directly, but I'm certain that if they felt that other investors were concerned about the arrangement, they would either change the terms or decline to take the opportunity. If Chamath doesnt want to participate, its his prerogative, and expressing his concern to the public really doesn't help his prospects of investing with airbnb or any other yc company.

Selling 5% of your total shares for $3,000,000 sets you up well for life. Not great, but well. At 4% interest that's $120k/year. After that, it's gravy.

Geht langsam das Licht aus? | emuscene.de – Mein Tagebuch
I'm an amateurish PHP dev; so I can't suggest specific projects to get into. BUT I've found the best way to go about getting into any open source project probably would be:

- Choose a project you've used if you can. (I went with WordPress for example)

- Decide whether you want to try helping out with the core project or you would prefer to make an add on

- Make sure you follow the docs, get the build for the project ready -- or at least try to following what the project's docs tell you to. Do your personal best to get a hang of the source--particularly the area where you're aiming at. Try your hand at writing some code.

- _Now_ reach out to the core developers and the community (IRC, mailing lists, forums)-- discuss any problems you faced getting your dev set up ready, writing/testing code or any concepts you didn't understand (don't ask stuff that can be answered with a lmgtfy), your idea. Ask for a simple bug to fix if you haven't managed to find anything.

- Develop it further -- get feedback from devs and end users -- release/submit a patch. Based on feedback, iterate and release the next version/new patch. Repeat!

No, it's not a huge percentage of their stake. They still retain massive stakes in a risky private company with a $1.2B+ valuation.

They're just diversifying a little. You wouldn't ask an investor to prove their commitment by putting 100% of their net worth in a single venture. Investors are diversified. Smart founders should be, too, as soon as they are able.

I disagree, I'd wager most people that use a google account already use it only for gmail, as there's little interest in logging in to their other services.
I have two issues with the article (notwithstanding that I had to look it up in google cache because the server wasn't responding).

First, while it's true that in this particular case iterating exposes gritty implementation details (because, to even define "iteration", you need to know about all the possible implementations and how they store items). However, that doesn't mean that the design of the interface can't be changed so that iteration is possible. The fastest I can come up with is adding a concept of inner set (that might or might not be null) and a method containsOuter, that by contract should not dig into the inner set. Then, for the adjoint set implementation you would have (in a more C-family style)

bool contains(T item)
{
bool res = containsOuter(item);
IntSet next = getInnerSet();
while(!set && next != null)
{
res |= next.containsOuter(item);
next = next.getInnerSet();
}
}

And we have iteration, without having to resort to implementation details. Barring any argument about aesthetic appeal of having this innerSet thingy, the code itself is simple enough to manage (heck, you could have that as a virtual method without any problems if you were in the frame of mind of class inheritance as opposed to interfaces).

Second, I don't see why we can't abstract this iteration business into an iterator. Fine, Java's iterators may or may not be a sprawling mess, but add lazy evaluation to the mix and you have a very, very powerful system. In particular, LINQ and Haskell handle collections quite nicely, and nothing stops you from implementing it in the OO language of your choice (if there aren't already some).

So how do lazy iterators help? Well, infinite sets become stupidly easy to handle. Heck, you can even self reference in C#:

static IEnumerable<int> Nats()
{
yield return 1;
foreach (var n in Nats().Select(x => x + 1))
yield return n;
}

Not that I recommend mapping your collection to itself, mind, but if you wished you could go all out with it. The point is, you can transform an infinite list, filter elements out of it, combine it with another infinite list and then take 10. It won't even take infinite time to compute.

So no, lack of tail recursion is not a detrimental problem to the OO abstraction. An annoying problem, yes, but no more than that.
The comma operator is a bad idea in most cases, but his idea of using it to unobtrusively insert a `console.log` debug statement inside an expression, is pretty clever and might actually be a sort of valid use for this language feature.

Also the way it allows one to formulate a `do { .. } while ( .. )` construction, is a nice and clever trick, but already violating the principle of least astonishment too much.

Build an open source project, and then we'll be dazzled by your awesomeness :)

Friendly advice: webapps development is generally just moving data around back and forth between DB and client. That's not much and pretty much anyone can do it. When you will be working at real projects, you'll see that the bulk of tasks that need doing come in 4 flavors: annoying tasks, yak shaving tasks, tasks you don't have enough knowledge to get done, and flow tasks. The data ping-pong is not the issue. So in the mean time do yourself a favor and learn as much as you can out of science, rather than faddy techs: backtracking, dynamic programming, A*, hungarian algorithm, support vector machines, red-black trees, markov chains, monte carlo methods, drinking philosophers, decaying windows, bloom filters ...

Sigh. The server should be back now. That'll teach me a lesson about TSTTCPW.
From what I understand, Chamath is okay with cashing out by selling your stock, but what the AirBnB founders are doing is just paying themselves a dividend of $20M (essentially just paying themselves a lump sum out of their funding round and not affecting any of their stock). Please correct me if I'm wrong.

Life is a natural right. Ensuring that I do not die in a train crash (or because I cannot afford health insurance, or because the factory I work at takes no safety precautions, or because the market choses crash-prone passenger planes, or because some idiot who doesn't believe in spectrum ownership jams my 911 call) all fall within the umbrella of protecting life. Yet these are decried as examples of an overly invasive welfare state.
It also takes a lot of pressure from you and maybe distracts from building the company.

it also makes it a whole lot easier if the company is on shaky ground and built up by hype, when everything does happen to implode in on itself. I'm not saying that this is airbnb's case but ...

I'm not saying twitter is a failure by any means, but none of the people that built the company are still there ( Jack Dorsey started square so maybe he is that small percentage of people that can juggle two amazing startups ). When all the founders cash out early, it just makes it questionable.
Gol gappas: Spicy Water balls
I was a but creeped out when they automatically logged me in to youtube. After I found out there was no way to log out of youtube without logging out of Google Reader and Gmail, I am checking my RSS feeds and email a lot less. There should be an option to opt out, it's ridiculous.
That's kind of an odd response to a bug - not adding a new test, but just noting that it didn't hit one particular project. Is Git's entire test-suite just 'the Linux kernel changelog'?
Thanks, I will give them a shot.
Great feedback. I'm glad to see this guide was helpful and I've made a few enhancements/updates based on these thoughts.

I new thinner/larger design would be nice, but I'm totally happy with the iPhone 4 at the moment. It's one of the best built and best looking devices I own.

My friends have various android phones with huge screens. The size is nice but they feel like cheap plastic.

A hardware upgrade with CDMA and maybe NFC with the same design is welcome.

I can wait another year for a new design with the iPhone 5.
This is my understanding as well. Chamath says that it's fine if all employees have access to this ability to cash out shares, but it sounds like AirBnB is essentially withdrawing money directly from the company, with no opportunity from employees to participate. He says it's basically a cash-grab that only the founders are participating in. I have a hard time disagreeing with him.

Did any founders of great companies ever do something like this? From my recollection, I don't believe Bezos, Jobs, Gates, etc ever did anything like this.
Only if you enable Instant Upload.
my point is that most people dont create a different google account for each google service they use. They use one account, for however many google services they do use.

my sister uses her account for gmail and picasa and for uploading to youtube.

my dad uses his account for gmail, picasa, and android market.

my mom uses just gmail

as, or if, people add Google services, they use their one account. The only normal person use case for creating more accounts is for having two accounts with one service, i.e. 2 gmails, 2 picasas, 2 youtubes, etc.
My gmail account isn't under my real name. I imagine Google will kill it at some point despite me having signed up before G+.

It's funny, I thought G+ could be the social network to replace FB and now it looks like I'll probably leave Google to avoid it. Weird.

It is a huge percentage of their funding, around 1/6th. If a company where to raise 6m and the founders got 1m not by equity, but by dividends! That just doesn't happen.

If the founder's want to sell some of their equity, I'm fine with that, but that is NOT what happened here. This is purely a pay-day.

If I knew my company was going to be the next eBay for realestate, why would you hamper your company by taking 21m off the table. This signals greed and/or being unsure of your future success.
Ask HN: Get ACM to allow open API access to their Digital Library
Open-access bibliography navigation tools have been totally left behind because of publisher paywalls, but the ACM should set an example by allowing outside app developers to access their digital index (if not the full text).

Check out Dale Carnegie's How to win friends and influence people. I was a skeptic at first, until I actually took the course.

To get someone to do something, you have to make them want to do it. That sounds pretty straightforward, but really, that's what it comes down to.

Others have suggested that at work, being a manager is the most straightforward way to make someone do something. That's because you have the authority to fire them if they don't.

You can influence people without being a manager though. Heard of the carrot and the stick? The carrot dictates that you can convince someone that something good will happen if they do something. "You might get promoted" or "I'll brag about you to the boss" or "I'll give you a cookie". An example of "the stick" would be if you threaten to complain about a peer to their boss that they're not doing their job.

Outside of work it's a lot trickier. If people think you'll do the work for them and they can just benefit, they're only too happy to go that route. You can appeal to their sense of guilt. "Hey Bob, remember last week when you said you'd send me a file? Just wanted to remind you". Appealing to their sense of justice works in some instances. The easiest way is if you can manage to get someone genuinely excited and then get them involved while the iron's hot.

If you get a chance, take the Dale Carnegie course. Read the book at least.

I'm working on a promising idea for TechStars Cloud (http://www.techstars.com/cloud/). I'm designing a product around OpenStack technology that will bring cloud storage to the average business. I'm looking for one or two developers with strong experience building back-end services to join me as co-founders for this venture. During the TechStars application process, this position is unpaid. We're working on this project in the evenings, after our full-time jobs. It's a gamble, I know. On the other hand, I think that we have a strong idea and if you join me now, we will be dividing our ownership of this venture equally amongst the three or four of us.

For now, this product is being worked on remotely. If selected for TechStars Cloud, we may continue to work remotely or we may converge in San Antonio, TX for the TechStars incubation stage. Obviously, you must be able to work legally in the US. No H1B sponsorship available.

About me: I have 18 years of experience as an engineer in the Internet industry. I've spent the last four years working with cloud computing for a major hosting provider. This idea is the genesis of daily conversations that I have with customers. It's a product that I think business is screaming for but nobody has perfected yet--and I think I know how to perfect it.

If you think you have the chops to take on a project like this, send me your resume and some links to projects that you've worked on, preferably on GitHub or the like so that I can review your contributions.

You missed the point, they take the money as dividens.

They are not selling their stock for that $20M lump.

The only 'foul' thing here, is that their employees (option holders) will probably get nothing.
Citigroup questions if US spectrum shortage exists
(I worked on the environmental assessment of the Acela back in the 1990's and worked with testing the first two vehicles off the line in Pueblo and along the NEC NJ "race track in 2000. The firm I was working for back then also did the noise analysis behind the revised FRA horn noise rules)

This article keeps popping up on various geek sites over the years. In addition to the points kposehn brought up, I'll add the following: FRA isn't the reason why HSR sucks. The reason that HSR sucks is because we as a nation don't want to invest in the infrastructure to make a good HSR system. At a minimum that means exclusive ROW (grade-separated crossings) with relatively few stops and long straight sections where it can get up to speed.

As for the FTA buffering standards - it really doesn't matter. Yes, the Acela is heavier than the TGV. That extra weight isn't why Acela service sucks. The Acela is perfectly capable of maintaining 155+ mph speeds for extended periods (I witnessed this myself in Acela enduracing testing). The power cars are more than capable of handling the load - during the first few months of Acela operation, there was a problem with the network connection that linked the front and rear power cars. To get service running until the power could be sorted out, the trainsets were run with only one power car operating. Running with one power vs both power cars (and pulling the dead weight of the second power car) only increased DC to Boston run time by 5 minutes. As for cost, the price of an Acela trainset is within the range of most other popular HSR trainsets (TGV, ICE, Pendolino, etc) albiet at the higher end. The effect of the train weight on track wear is minimal as it's the unsprung mass of the train (essentially the wheels, axles, traction motors and brakes) that is proportional to wear, not the static train weight. And train weight has nothing to do with noise.

kposehn already commented on DMU but I'll add that the biggest impediment I saw to transit agencies adopting DMU's was that since no one else in the USA had them, transit agencies didn't know what to expect in terms of maintenance, operation, and environmental effects. In fact FRA and FTA were essentially begging transit agencies to try them, and it's only been recently that they've been operating in Vermont and other locations.

Finally, regarding FRA horn noise rules: first of all, the preemption of state horn rules originated with Congress who directed FRA to get involved with horn noise (Google "Swift Rail Development Act" for more information). But the reason those rules exist is because whenever there is a grade crossing fatality, inevitably the next of kin sue and all too ofter win in court. As a result, there is a tendency to do anything and everything in the name of "safety" on the part of RR operators, agencies and regulators. As long as this remains true, horns are going to be part of rail travel.

edit: btw we had this discussion at ArsTechnica back in 2008 (I'm Anechoic there as well): http://arstechnica.com/civis/viewtopic.php?p=2671067
The difference here is that the founders are somehow diversifying without actually parting with any of their investment. This is simply a massive bonus to the founders treated as a dividend (probably for tax-avoidance purposes.) The fact that it's not available to most employees, even those with stock options, if problematic, if you ask me.
