November 2013 - 350 Million Photos Per Day

That's some serious growth. Seeing that much growth over a nine month period probably has a huge influence on why they think a better offer will come around.
Conversely - what market?

Snapchat's monetization potential is staggeringly limited. Snapchat adds ads, they annoy people, everyone moves to Poke or some other platform which does the same thing.

Facebook at least, have a way to use the data from Snapchat to add value to their other products - Snapchat, not so much.
Where would you get the high-amp power supply though?
Signal processing mysticism repeats itself every 20 years and has been fueled by tremendous hype since its debut 400 years ago:

1. Linear Regression (which, admittedly, was amazing)

2. Fourier Analysis (which is linear regression on orthonormal bases of functions. it blew people's minds)

3. Perceptrons (which is linear regression but with a logistic loss. it went back to its old name of "logistic regression" once its insane cachet of biological plausibility faded)

4. Neural Networks (stack of logistic regressors. popular with people who didn't know how to filter their inputs through fixed or random nonlinearities before applying linear regression)

5. Self Organizing Maps and Recurrent Nets (which were neural nets that feed back on themselves)

6. Fractals (which is recursion. they were useful for enticing children into math classes)

7. Chaos (which is recursion that's hard to model. useful for movie plots)

8. Wavelets (which is recursive Fourier analysis, and probably still way under-used)

9. Support Vector Machines (which replaces logistic regression's smooth loss with a kink that makes it hard to use a fast optimizer. often conflated with the "kernel trick", which appealed to people who didn't want to pass their inputs through nonlinearities explicitly)

9. Deep Nets (which are bigger neural networks. the jury's out whether they work better because they're deeper, or because they're bigger and require a lot of data to train, or because they require a programmer to spend years developing a learning algorithm for each new dataset. also whether they do actually work better).

Once this Deep Net thing blows over again, my money's on Kernelized Recurrent Deep Self Organizing Maps.

(On a serious note: MNIST is considered a trivial dataset and doesn't require the heavy machinery of deep nets. linear regression on almost any random nonlinearity applied to the data (say f(x;w,t)=cos(w'x+t) with w~N(0,I) and t~U[0,pi2/]) will get you >98% accuracy on MNIST.)
the best thing about supercapacitors is that they don't have a liquid inside. It means that (at least theoretically) they can be of any form and thickness. So, (again, speculatively speaking) they can be a part of laptop frame.
Agreed. I was impressed by the RC pilot's skill, and noted the craft's behavior was, at times, very insect-like. Or hummingbird.

... and I couldn't help but think, if a life-size helicopter were even capable of such maneuvers, its human occupants would likely die from the G forces.

Clearly such maneuvers seem only possible in an unmanned craft.
The mall is more "consumer friendly" ;) The video is from someone who lives RC.

I've only seen one live demo of a "pro" RC pilot doing his thing and saying it was awe-inspiring is a massive understatement. These are folks that eat, drink and breath RC and the amount of time and enthusiasm spent is really astonishing. If anyone can find a way around the laws of physics, it's those in the RC community.
How does HSTS deal with expired certs?
The problem is not the rationality assumption per se. It is that the set of inputs and constraints to the decision process considered in classical economics is sufficiently narrow and incomplete that it does not produce a realistic output. Actors generally appear "irrational" primarily because classical economics simplifies the modeling process by discarding relevant context that influences decision processes for the sake of simple analysis.

Also, "rational" is contextual, not objective or axiomatic in any real-world finite computational system as a matter of mathematics. This is an important distinction often ignored. As a consequence, "irrationality" can be generally defined as "making a decision from a different contextual basis". Again, this defeats the desire to create absolute rules of economics that fit in a soundbite.

Economics is perfectly capable of dealing with the complexities of real-world actors in theory. In practice, most economists attempt to reduce the complex dynamics implied by the theory into trivial theorems that are easy to turn into government policy. This is somewhat understandable because even approximating a pure model is computationally prohibitive. This provides a lovely framework within which any economist can come up with a narrow model that suits their particular ideological proclivities. You rarely see an economist that properly recognizes the constraints and assumptions of their model but those limitations exist nonetheless. Advanced computer science will allow us to implement the more general models directly regardless of whether or not the results are politically convenient, but it may take a while before we see it.
20$ million is barely anything if you want to actually make a difference, as opposed to just surviving without having to work.

It doesn't have to be a high-amp power supply- you could use a low-amp supply to charge up another supercapacitor, then use that capacitor to charge your laptop's supercapacitor.
This comment adds nothing to the discussion, because absolutely no one reading HN is unaware that that was preventable, and serves no purpose other than to mock someone building things. That should be anathema here.
Err, no it doesn't - the viscosity in LB is a function purely of the relaxation time (for LBGK anyway). Nor do you need to do any simulation repeats to average out the noise. The main weakness of LB is that it's not as numerically stable as a lattice gas method.

The thought of a weaponized version of that is terrifying. A weaponized and non-human controlled version is straight up Cyberdyne level stuff...
Exactly. They can afford to be a little greedy, but shouldn't push their luck. Their success as of now is very much based on the vogue factor. Geocities sold for over 3.5 billion, on the verge of the dot-com collapse.
"it may or it may not crash soon, it has many advantages and disadvanteges, there's stuff to be adressed"
The big question is how long they can retain the charge. Supercapacitors generally have a much higher self-discharge rate than batteries.
I don't even think this is really even targeting companies who are thinking about virtualisaton. I'd guess the early adopters will be the companies already using desktop virtualisation of some sort or another who already find it a management nightmare.

This sounds expensive compared to a stand-alone PC, but in terms of all the licensing and hardware required for in-house virtual desktops, it's reasonable.

The big difference is Amazon is now taking the 'risk' for sizing the infrastructure for virtual desktops. No need to estimate capacity for servers or licensing. Ten users next year, a thousand? You know it's going to cost you $x/user/month and no more sweating about server capacity, license compliance or negotiation.

Amazon 'Direct Connect' would also probably be a necessity for a good user experience, again limiting this to the pockets of people who'd already worked out thin clients were 'worth the trouble'.

Given the monthly cost of these is lower than the equivalent 'On-Demand' instance cost, it wouldn't surprise me if they had some sort of over-subscription 'special sauce' in the mix as well. Everybody doesn't flog their desktop 24/7...
If you're impressed primarily by absolute dollar amounts of value added, then sure, U.S. manufacturing looks good on a bar chart comparison of G7 countries.

However, the rest of the FAS report is stuffed full of metrics showing the rapid decline of the manufacturing sector.
This is very much on-point. Once I launched 5KMVP, people no longer focussed on the tech choices I made. They do ask what my stack is - I think because most of the crowd I cater to are more savvy and are curious - but for the most part they just care about getting an MVP at the end of the engagement.

It also works both ways, now that I am able to focus on just giving them an MVP I make recommendations along those lines. I can recommend that they use a Bootstrap template and they don't see it as "cheap design", but rather a "an affordable, clean interface that helps validate their hypothesis". Frees me to work on the business logic of what they want and the quirks of their application. I also make hosting recommendations based on who I know they are (people trying to get projects off the ground, so they are cash-flow sensitive).

The difference between the clients I get now and the ones I used to get are night and day, because there is no ambiguity in what the client wants and what I will give them.

Best decision from a "freelancing" perspective I have ever made.
Groupon-effect.

In 2010, Google offered to buy them for $6B. One year ago today, GRPN hit its lower point in history: its marketcap was less than a third of what Google offered originally. Andrew Mason was fired after soon after, after missing estimates, again.

The stock recovered considerably since then ($6.9B market cap today), but it's a reminder for young entrepreneurs that the market is ruthless with one-trick ponies.

Unless you have something on the table from Facebook, I fail to see what's their long term strategy.

This is just about the most absolutely bizarre thing in the world for me to see my High School football coach on the front page of Hacker News. I attended Pulaski Academy (PA) 6th-10th grade and played football there from 7th-10th grade, 1 under Coach Kelley who was then the Defensive Coach while I was a cornerback (and tailback).

As coaches go, Coach Kelley was smart, far smarter than any coach I had at Plano West, one of the premier school districts for football in Texas. He pushed us hard, had a great sense of humor, and was out to win. PA was also the best school I have ever attended (I also grew up in Rancho Santa Margarita in Orange County, CA).

I guess what I'm trying to say is that while this is completely bizarre to find it on a Silicon Valley tech site like Hacker News, I honestly can't say I'm all that shocked. Sometimes when you meet people, you just understand and know that there's something different about them, a potential for greatness, that they are a mold breaker. Their current circumstances may be unexceptional, but you have confidence they will go on to do great things. I think this is of course what we (HN) share culturally with a football coach from Little Rock, AR: a desire to think outside the box, to break the mold, and achieve what little greatness we believe we are capable of achieving.

I owe a great deal of my professional success to Coach Kelley and Pulaski Academy, so seeing them realize this level of success by being different, smarter, fills me with pride and warms my heart.
I understand your unease. In this case I totally pulled this equation f(t)=0.002t^2 out of nowhere. It is just "some" function that satisfies f(0)=0 and f(600sec)=720MB.

I basically skipped (invented) the modelling step. In practice you would observe the download size f as a function of time t, and then ask yourself "which function f(t) correctly describes what I see." I wanted to describe a download that gets faster and faster with time, so I picked a quadratic function f(t)=At^2 as a template, then chose A=0.002 so the function matches the problem statement.

Suppose instead I wanted the download rate to be uniform (constant download speed), then the function which describes the file size would be of the form f(t) = mt+b. More specifically, the function would be f(t)=720/600t+0=1.2t. (You can check that f(0)=0 and f(600)=720, as in the problem setting).

In general, once you become familiar with the main function families f(t)=mx+b, f(t)=ax^2+bx+c, f(t)=Aexp(kx), f(t)=ln(x), f(t)=Asin(kx-ϕ), etc, you will be able to describe real-world phenomena by using one of these equations. This ability to "model" the real world through mathematical equations is one of the super-powers that comes with math knowledge, but my download example doesn't quite manage to communicate that. I will have to rework it...

For a slightly better example of "modelling" using equations, check out page 26 in the PDF preview: http://cnd.mcgill.ca/~ivan/miniref/miniref_v4_preview.pdf#pa...

The email switch didn't work out so well.
At least on Android, you can send SMS through the Facebook app, which is what I assumed they were referencing here. It doesn't send the message through Facebook in the sense of web-to-SMS gateway, though; it's just that Android apps are allowed to send SMS, and Facebook has built that functionality into their app, so that 'all of your messages are in one place'.

There are a lot of non-abusive reasons why Motorola might start by pricing the Moto G as if it were imported, even if most of them will be manufactured locally.

For instance, depending on how far along local production is, Motorola may well have imported launch stock. Or Motorola may be worried they'll end up stuck between importing stock or leaving sales on the table if they underestimated Brazilian demand. Or maybe there are issues with some imported parts or ...

Once they reach a steady-state where they can forecast demand and Brazil is comfortably a net exporter of Moto Gs, it should be different, but, in the short run, Motorola has sensible reasons to be cautious.

My tone was meant to be gently humorous, not seriously precise. I was reminded of a guy on another site who was backing up his arguments with quotes from a book -- that he wrote. When someone called him on it he didn't miss a beat; he said it was a good book four years ago when he wrote it and still a good book worth quoting.

It's amazing, I never saw the point of Pinterest until I saw my wife using it.

Snapchat on the other hand? I can understand the key selling point - it's basically the naked girl app. And I'd wager that a good proportion of their traffic could get the receivers arrested...

I'd have been all over it when I was a teenager, though.
The Moto G launch featured a large number of accessories (covers, shells, headphones, ...). I suspect part of the plan here is to price the phone aggressively so they can make more money on accessories.

people have been shown, time and again, to behave economically irrationally

Likewise, choices that appear irrational may turn out to be entirely sensible but for the exclusion of relevant factors. Having been quite poor in the past I can certainly distinguish between irrational choices of the 'oh fuck it, let tomorrow take care of itself' variety and rational ones of the 'this is inefficient, but satisfies constraints' type.

As an example of the latter, consider riding the bus. In many places you can get a monthly pass at a substantial discount to paying multiple fares every day. But for someone who is un- or under-employed, the expected value of purchasing the monthly pass is quite different from that of someone with a predictable commute; if that person makes the wrong guess about how often s/he will travel over the month, it can result in a significant opportunity cost.

Then there's the even simpler case of the person who can't accumulate enough cash at a time to buy the monthly pass, but who won't be able to get paid at the end of the week without taking the bus to work each day. Absent credit facilities, paying bus far on a day-by-day basis can be perfectly rational when viewed in the individual's overall economic context. Unfortunately, economics textbooks don't devote much attention to multiple inelastic constraints.
Yeah, if Poke couldn't take down Snapchat, then I don't know what hope this has of displacing those other apps.
The announcement event was in Brazil. I'm sure the price will be around there, given the phone is being produced there
I agree with Anigbrowl. You get what you pay for. If you buy cheap headsets or use ones that come default with your devices, you should in all seriousness expect a pretty low life span even if it exceeds that expectation.

Pay $100-ish and get a quality pair. I've had the same one for about 5, maybe 6 years, still works flawlessly.

As for your second question, always worth trying Kickstarter if you think its worth competing.
I first started at a small web shop that was quite flexible. There were a few of us who more and more starting working at home, but came to the office the same 1 or 2 days each week, to work face to face and go to lunch...

Fast forward a few years, and knowing that I could work effectively as a remote worker.

I co-founded a small company with a guy in a larger city. We ended up setting up an office in that larger city, but I never moved. Travel as needed, but it wasn't that much. Then got acquired. The acquiring company has kept me on contract since then, as a remote worker.
Huh, that's an interesting way to feel! I wish I remember what AIM felt like better; I was so young when I used it that any chance I had to IM people was exciting. I was probably an absolute pain in the ass.

D'you think this could be — at least in part — because Facebook is an always-on environment for a lot of people? They're not explicitly on to chat, so there's more of an unstated barrier to beginning a conversation.
This is only really a shot across the bow if Facebook ports their messenger app to feature phones.

WhatsApp and the like didn't invent mobile messaging, they just went through the trouble of building J2ME clients across all the cheap handsets found in the developing world so that mobile messaging was available across all devices. Facebook isn't going to make any dent at all in the developing market unless they do the same.
Yeah, developing nations like most of Europe and so on...
You're nitpicking. It's a hypotethical. He's trying to show how something that is not profitable right now might still have positive value.

The point of the question is whether you expect the person to earn enough that getting 50% of their life income would be worth 100, 1k, 10k etc. today, not 'how likely that person is to actually keep the deal'.
Note to reader: the supercaps in the article aren't being used for long-term energy storage.

When a car brakes using magnets, a huge quantity of power is generated by the magnets. In a typical setup, this power value is much higher than the maximum rate at which the lithium batteries can absorb charge.

From what I gather, what this article actually means is that these supercaps will be used as energy couplers between the regenerative brakes and the lithium batteries. They aren't actually replacing the lithium battery.
I hate the direction FB is going with the messaging system. It doesn't work well when you try to send anything longer than a few words. Send an email you might say, many people don't read emails as much as they read FB. Sad but true.

/rant
So is the idea here that you would use these supercapacitors as the primary energy store? Or is the case that you would use them to quickly capture the energy from regenerative breaking and then use it to slowly charge traditional batteries over time?

Hold on, why was my response badly researched?

The point was that NodeJS and PHP were pretty close, and I posted (before the update) that I'm sure Node could go quicker.

You run either of them in suicide mode to RUN ALL THE CONNECTIONS and you'll get a speed up. The point is that NodeJS is not magically 4 or 5 times faster than PHP, they're about the same when you the packages you use support the async approach. This update proves they're exactly the same, but similarity is all I was going for.
Believing a company is overvalued is not sufficient reason to short it. You must also have a reason to believe that other investors will realize it's overvalued sometime soon too.
[This is not a comment on Snapchat specifically, so I'm going to take out the reference to Snapchat and replace with "X"...]

"that being said, the market potential for a google is quite obviously higher than the potential for X i think. I can't imagine a future world where X is worth more than google, and if it is, it's almost certainly because they used that valuation to pivot and make something more worthwhile."

You can only say that with the benefit of hindsight. At the equivalent stage in Google's life, you might well have been equally skeptical of Google -- and a lot of people were, including at various times their founders and their VCs. It was widely known at that time that search was a bad business -- in fact, the assumption based on several years of prior data was that it was a loss leader for portals. Google itself didn't start with the keyword advertising model, they developed that along the way (in part based on work done earlier at Goto.com, which hadn't worked nearly as well for them).

Equally, at the equivalent stage in Microsoft's life, it was well known that PCs were a toy and that people wouldn't pay for software. At the equivalent stage in Oracle's life, it was well known that data belonged in hierarchical databases on mainframes, not in relational databases on Unix servers. At the equivalent stage in Cisco's life, it was well known that proprietary networks like SNA and DECnet were standard among people who paid for things and that the Internet was only a toy for academics. And so forth and so on.
