Ask HN: How the hell is Whatsapp worth $18 billion?
$40 per user someone calculated to be.

My question is, how is it $40 when the app itself is free and doesn't get the $40 from the user?

How will Facebook monetize it?

The moment they track users or show ads won't people leave and a new Whatsapp emerges?

Please help me understand how MAU without pay from user's wallet works because porn sites have a lot of MAU and they are not getting bought out, and they are free and offer value to the users as well.

> I'm really hard pressed to come up with a more convoluted architecture than the x86.

At the risk of coming off a little more contrary than I intend: seriously, who cares? joezydeco was talking about teaching an assembly language with "training wheels." 8086 assembly without any doodads works for that. It's useless for normal people but no more useless than 6502, and the student will have development tools that are actually friendly to play with.

The nice thing about learning x86 assembly is that embodies the entire learning curve. If you want to inflict all the horrors of assembly language on yourself - a pointless pursuit for anyone not writing a compiler while simultaneously eating paste, but hey, whatever - x86 lets you start small and work your way up.

I'm just not clear on who needs elegant assembly language programming (outside of compiler writers, etc.). Doing it at all represents failure. The point of an assembly language class is to be very quick and make the student appreciate what C does for them, IMO.

I wonder if buying up MtGox BTC would work as a strategy to claim damages in a lawsuit. Kind of like buying up low-value debt and then collecting on it.
> But in absence of this conflict, or the external meaning that is the cause of the (perceived) conflict, they wouldn't know what to do with their own existence

What nonsense.

> "Google" is nothing more than a tightly-bound collection of humans.

Yes, and collections of humans tend to exhibit emergent properties / behaviours which are not necessarily ideal in all respects.

Discussion of these properties / behaviours, and their desirability, is not a bad thing.

> They see the world in a black and white. "Us" and "them".

This is humorous to see in a post expounding a false dichotomy between the "two" types of people in the world.
Linux is not a course typically taught in universities. For the same reason they don't teach courses on Excel, Word, Photoshop, Firefox, etc.
It's not unlike what a "Full Tilt dollar" was back when Full Tilt Poker and PokerStars (and others) where raided by the FBI/DoJ and had their .com seized and sited unavailable for some time.

Full Tilt didn't come back up for weeks... Them months. People on big poker forums would sell / buy "Full Tilt dollars" at a lower price than the real dollar price. People try to determine what's the probability that accounts will be able to unlock their funds: if you're thinking there's a p = 0.3 that Full Tilt will pay back their users (or that there's a 100% probability that they would pay back at $0.30 per Full Tilt dollar), then it makes lots of sense to buy other people's Full Tilt dollar / accounts at, say, $0.20 per "Full Tilt Dollar".

A MtGox BTC is just that: it's a BTC that may or may not be real, that may or not be paid back or that may be paid back, but not in full.

You even now have people buying MtGox BTC from other users at a lower price than the "real" BTC price (of course there's a issue of trust involved between users buying/selling MtGox BTC but that is another topic).

Regarding Full Tilt: all the players ended up getting paid in full. So people who bought Full Tilt dollar for way less than $1 per dollar made a very good deal.

For the little story (if I'm not mistaken) Full Tilt has now been bought by PokerStars and is operating again (but not in the U.S.).

MtGox has both "MtGox BTC" and "MtGox $". We'll see in a while if they turn out to be equivalent to 100% BTC / $ or 0% BTC / 0$ or something anywhere in between.
What, only one SIM slot, really?
Well, something that anemometers, thermometers, hygrometers and pyrometers can't tell you is what the air smells like.

If the animals that reacted differently, for example, to air with a different blend of gasses, and that different behaviour caused that animal to survive the surprise snow storm, you'd expect that this behaviour would become more widespread in later populations of that animal.

The genetic "memory" of the cold event would be carried by the surviving population, since only animals with behaviours that contribute to surviving the cold event end up procreating.

Now what if caterpillars change colour in response to atmospheric gasses, temperature, or diet? Would a caterpillar that changes colour with temperature be a suitable indicator of a coming cold snap?

It's fine to classify programming languages. It's not fine to get confused between a programming language and a way of representing a particular program.

For analogy, there's only one true physical Earth, but there are many possible maps (representations) of the same area: one showing the temperature at the surface (using color), one showing wind direction at various points, one showing roads, etc. Which map is correct? Which map is best?
The FCC’s Plan to Reboot Net Neutrality Might Transform Municipal Broadband
Yeah yeah, the Android code suffers from the same lack of good OO design/code organization as the iOS code, but frankly it's such a simple sdk, it won't matter until it's feature rich and complicated. Anyways, some immediate concerns as I see it:

1. Sending requests every 10 seconds (and/or at every onPause) is no-good for battery life. Please, let the radio power down once in a while!

2. Using DefaultHttpClient with no connection pooling

3. It's doing a ton of work, allocating objects, logging events, in every onResume/onPause...I don't like this design. That includes when I get a pop-up message from another app, even if I dismiss it immediately.

4. Would be nice to register for activity lifecycle callbacks for api level >= 14, so people can't screw up the implementation.

Fraud is a leading indicator of a bubble popping. Everyone with a vested interest in a strong startup economy should want to see this behavior punished harshly. It won't stop the air from going out of the balloon but we'll have a softer landing if we all behave ethically.

Great! My experience has been that packages simplify automation and play nicely with DevOps tools like Puppet and Chef. It's dead simple to write a recipe to install a package, whereas things get complicated quickly when you try to write a recipe to orchestrate a build process, e.g., git pull, install compilers, ruby-build, install gems, compile assets, etc.

To help convince folks on the value of packages, you could try pointing them toward Michael Stahnke's presentation "The Balance of Packaging vs. Puppet Manifests":

Read the FAQ. Transfers between MtGox accounts have never stopped working. https://www.bitcoinbuilder.com/faq.html
MtGox has internal transfers between accounts on their trading/accounting system. These are not actual transactions on the Bitcoin blockchain.
Michael Arrington runs into a bunch of VCs having dinner together and that is somehow conclusive evidence of collusion? What?
The (bad) article discounts at least the following:

1. Often acquisitions thrive under their new overlords (think android, youtube, instragram). They might also need the financial resources of the purchaser to aim higher.

2. Acquisitions increase the # of potential angel investors, which leads to more money for startups. Look at what PayPal's acquisition has done for innovation (it's famous "mafia" ended up funding and/or founding Facebook, Tesla, Palantir, Spacex etc.)

3. An acquisition culture leads to more examples of successful founders, which leads to more people wanting to be founders.
MtGox allows internal transfers.

It's worth that much because it has the growth potential to overtake Facebook. The value is in futures. In order to keep your lead in the market, you sometimes need to buy out the competition. I'm not an expert on it, but that's just how I understand it.
This just adds a depth camera to the phone and uses it and the visible light camera to map the space and orient the device. If a human is disoriented in a no-visibility situation due to smoke, the cameras will not likely be able to orient them either, except maybe something like a power outage, where visible light is unavailable but the depth camera can still function.

Perhaps also investigate allowing customers to slave their own secondary DNS, too? (That is, allow AXFRs.)

This has been a feature requested for, as far as I can tell from the support forums, four years now. It should be possible to make this allowed/disallowed per-zone, and as far as I'm concerned, I don't care who is able to download my tiny zone file. It would allow me to add more diversified DNS servers in the face of things like a DoS against Namecheap.

> To be a safe fulfiller of a wish, a genie must share the same values that led you to make the wish. Otherwise the genie may not choose a path through time which leads to the destination you had in mind, or it may fail to exclude horrible side effects that would lead you to not even consider a plan in the first place. Wishes are leaky generalizations, derived from the huge but finite structure that is your entire morality; only by including this entire structure can you plug all the leaks.

Humans can mostly differentiate between good and bad (ethics), but we don't know how we arrive at those conclusions (metaethics) because humans are terrible at introspection. Also, there's a ton of gray areas (e.g. the trolley problem). So rather than define all possible edge cases, it's probably less difficult to understand human decision-making from first principles and model our FAI accordingly.

I'm pretty sure the quality of American candy has continued to decline. Or, I may have acquired higher standards in the intervening time.

It seems like there have been some very large DDoS attacks recently. Can anybody point me to a link explaining what changed recently that these things suddenly popped up?
I'm a big believer in private enterprise. But I also believe in local control.

The more local, the better, and the less subject it is to lobbyist control.

Comcast may be a private company, but its knee-deep in the Washington game. The public/private distinction is not as clear as one might think.

I think we'd all be better off forming small co-ops that own the last mile. That would make it easier to make providers compete for business. Only one last mile, with lots of options to connect.

Government likes to have a single water system, a single grid over a geographic area. But that makes the entire system more susceptible to failure and also fairly immune to competitive pressure.

If your local monopoly grid isn't robust, you can't switch. And huge areas can go dark.

With competing grids, your co-op might go dark. But there just be a competing grid up within walking distance. And these grids would be competing on reliability, just like cell phone carriers do. You'd have more options than going to a public utility commission meeting, speaking your piece and then having them do whatever is politically expedient.
why is crowdtilt powered by perl dancer and crowdtilitopen by ruby on rails?
Shawn, Beep CTO here. CrowdtiltOpen is currently hosting our e-commerce site. I can't say enough good things about you fine folks! The service rocks, the team is fantastic. And we get to keep all the incoming link juice (because it points to our domain), and get a fully customized site, that looks exactly how we want it to.

If you want complete control, while leaving the hosting up to a team that rocks and knows how to do it (they handled AdBlock's campaign for example, tons of traffic) CrowdtiltOpen is the way to go.

Technically they could do this down the line. But it'll be very difficult to enforce as bitcoin is a global currency. Your laws may not apply to my country, and everyone else will be using them.
Visual odometry is getting quite accurate. For example, it is used on the Mars Exploration Rovers (Spirit and Opportunity) to improve the position obtained from wheel odometry [1]. As you mentionned, the big accomplishment is doing this in real time on a mobile device. On a typical mobile ARM processor, it would probably be very slow and drain the battery in no time. That's why they are using a custom coprocessor designed specifically for image processing and computer vision. The next challenge is porting the existing visual odometry algorithms on this new processor. It looks like hiDOF did the implementation [2].

Got my invite from several months ago when it was Crowdhoster! Scant weeks away from using it! I was going to forward it to LPP, thinking they would (and didn't) never get to my email about their own crowd-funding effort, but in the intervening time, I've decided to do for them what they probably wouldn't have time or resources to even start pursuing. No details for now. It's a stealth crowd-funding campaign @_@. Go FOSS!

Facebook mentioned the volume of messaging sent through the application is approaching that of the SMS volume of the entire world. So, it's like buying a huge (the largest by far) global telco which only allows texting. In some poor countries, that's all people really use a cell phone for anyways. Calls are too expensive, so you see far more people texting than talking.

As big as thing thing is, it's possibly headed to 1 billion users. I'm assuming that's about as massive as anything which exists right now. It's one big platform among very few that are operating at that level.

I just don't think there is any comparison. Money doesn't matter. You make big plays. If Zuckerberg were thinking small when he built Facebook, it would be a small e-commerce store selling T-shirts or something.

:) sure. let me just build a site right quick and link to some random person's LinkedIn profile. I bet I could get a good 12 hours of yokels using it before it was remedied.

If it's truly Josh Jones of DH, he is not instilling too much confidence. He's even piggy-backing on CloudFlare's SSL... at the very least, he could have opted for an EV SSL that showed that some certifying body truly checked out the individual running the site.

This smells scammy... real badly.

That's where the potential for speculation comes in. If you can buy Mtgox BTC and manage to extract it from Mtgox systems at some point in the future, you can make a lot of money by buying for Satoshis on the BTC.

On the other hand, if you buy these, MtGox never re-enables the ability to transfer the BTC they hold on your behalf into your own wallet, and then can't get someone else to take them, you're completely out of your original purchase capital.

I don't think anyone expects MtGox to survive as a major player after this, but if you can get it out of their systems and into your own wallet, 1 BTC that's currently in MtGox is as good as 1 BTC anywhere else. What's being speculated on here is the confidence that MtGox will at some point restore the ability for people to transfer BTC out of their system, and the confidence that people will be able to extract (at current exchange rates) at least 20% of their BTC held there.

Please see the part I said about there being a "glaring incompatibility" between startup culture and the banking industry. I'm not saying it's Simple's fault. I'm saying that what it's offering (easy to use banking done mostly from your phone) is ultimately beholden to all the stuff it loses from not being a traditional bank (long delays between transfers, no easy way to deposit a check). And that ultimately holds back Simple's promise.

The banking system sucks and is way behind where it should be. Simple, for all the amazing stuff it does, exposes some of those huge faults by tripping into them. And in many cases, they're problems they simply can't avoid because of the way the system's set up now.

I hope Simple becomes more successful and uses its corporate parent's clout to fix these problems once and for all.
I hope one of those is Haystack. I've been dying to play around with it. It was originally supposed to be open sourced but they changed their mind.
It's kind of like the Turing Test -- relatively easy for a simple program to simulate insane or stupid humans.
Mtgox Bitcoin price is 5:1. If you really think the chances are 50/50 that Mtgox recovers, it's a good buy.
I completely agree with the examples you cite. However the parent was giving examples about auto-correction for user's contacts. That is user-specific data and there's no need for it to be shared with a third-party.
Right, but that's securitized and sold to investors. And if I'm a bank, I can go to the fed discount window and get cash cheap.
