I wouldn't limit that to developing nations, pretty much everyone I know uses WhatsApp in the UK, simply because mobile coverage is so poor that it's easier to send a Whatsapp than it is to send an SMS.

I seriously hope it doesn't cause any issue for these companies, I've just got back from a few months travelling and Whatsapp was invaluable.

Lol you people are funny. VC's will certainly miss on startups, YC included. The goal isn't to get funded. It's to build a sustainable growing business. Everything else is just a benefit.
Script evaluated in a web worker would still have access to your application's cookies and would be able to interact with the server with the user's credentials. You probably don't want that.
I like this. It's all about positioning. I'm technically a freelance writer/editor, but I've found that when I call myself a "content strategist," I can command much higher wages doing the exact same work (since I have to do social, deep analytics, etc. as a writer anyway).

If they're on Facebook all their contacts will be on Facebook Messenger. Does Facebook have poor market penetration in Asia?
> But the real point -- which is a huge one, as far as the field of economics is concerned -- is that the "rational (and by implication, homogeneously rational) actor" presumption is under fire.

Er, no, while people have been saying that this is the "real point" of various stories on internet discussion fora at least as long as I've been on internet discussion fora (which goes back to the latter half of the year 1990), its really not. The rational actor model (whose role in economics is much more limited than many people seem to think) has always -- from the day it was conceived -- been known to be a simplified model (like the "perfectly competitive market") which is a good-enough approximation for some real world interactions but fundamentally not true (it assumes, among other thing, what amounts to effective omniscience -- at least where it concerns any decision that has any impact on the actor's own experienced utility -- on the part of all actors), and also not even good enough to be useful for many important situations.

No one anywhere in the social sciences thinks the rational actor model represents the underlying reality, and in economics particularly it (along with perfectly competitive markets) is baseline that works both as a basis for a highly idealized model that is important pedagogically and often useful as a basis for describing real world situations in terms of variances from (e.g., explaining empirically derived models of real-world behavior in terms of how the empirical model differs from idealized model and connecting that to a theory of how the real underlying processes differ from those that form the basis for the idealized model.)

It makes no sense to link the duration of the copyright work to the life of the author. Say some one writes a book and then promptly gets hit by a car. Why should their book have less of a copyright term then a book written by and author that goes on to live for 80 more years. Copyright term should be set number of years after first publication. 20-30 years would be reasonable.

Copyright is absolutely necessary to allow authors to make money from their work. Short term rights, 10-30 years of so, benefit the authors the most. Long terms of 100+ years only favor the distributors.
There are some gross simplifications here:
8. Wavelets are not "recursive Fourier analysis". If you want to make it simple, it's more like a spatially localized Fourier extension. I agree that they are under-used though.
9. SVM: the "kernel trick" is a big deal because sometimes defining a vector-space of linear features out of non-vector objects won't give you a good performance, and you'd better define a dot-product.
10. Deep Nets are not only bigger neural networks. The buzz is about how you train them. It's about improving how you train a net in general.

I would say that the next bing thing is more:
Realizing even more that Neural Nets is an optimization problem, and instead of using some heuristics, wait for some Russian mathematician to derive the right SGD schedule / batch solver for the problem. Then what the 1,000 of Google computers have been able to do for the cat face detector, we'll be able to do it on a smartphone chip.
People have to realize that Deep Learning is a bit of a "brute force" solution for the moment (each node is a linear model). We need to derive smarter algorithms.
To those complaining about this, you're not the target market.

I was on a train from Chicago to Detroit a week ago and there was a group of about 10 high schoolers sitting behind me. We got talking about iPhone apps and I asked what was popular.

They all agreed Facebook was not as cool anymore and confessed to being addicted to messaging apps that their parents couldn't check up on like they could with texts. Snapchat, Kik, and Whatsapp were among those mentioned.

It's interesting because if you look at these apps in the App Store, the screenshots are definitely targeting that age demographic as well.

Facebook is losing ground fast for this age group. The group that has grown up using Facebook and is now moving on to other mediums. This release looks very promising in helping to win back that interest.
Grunt Tips and Tricks
I have to ask; are there fair use laws in Europe? I was always under the impression that was a US law.
Just run a couple of them, its not hard right?
That's kinda stupid garage-scienticism to be honest.

- TFA does not mention the stability issue. Guess why people and drones fly tri, quads, etc and not regular helis. Yeah. (a simplification: stand on one leg. Now stand on 2, and use your 2 hands as well. 4 legs. Stable heh?)

- Yes single large prop is more efficient than many tiny props. But put many large props and the difference isn't so big. Let's take a $1000 ultra efficient quad: www.youtube.com/watch?v=t0SR5bzuFq4 yeah thats 100min of flight time for something smaller than the Align Trex of the video. And it's cheaper too.. The trex flies 5 to 10minutes (6S 5000mah). At equivalent batteries, the trex flies 25min (hint: the trex is not made for efficiency, it's made for 3D). An average camera-less quad flies 10 to 15min (3S 3000mah).

- TFA compares a $5000 Align Trex 700 with a bunch of expensive upgrades - the top of the top - with one very good pilot with decades of training... to a $200 toy.

- $200 toys made of wood and plastic flown by random people are actually pretty good at acro. Why? Because being more stable they're much easier to fly. Ex: http://www.youtube.com/watch?v=qzu5eSZqKpY http://www.youtube.com/watch?v=8QP0QjIsTTM

So yeah. Not exactly impressed when that's coming from a university. I expected much better.
Why do you need the read/write external storage permission?

Also, I saw a cool concert in your app, where tickets were $64. Then I found tickets for it on ticketmaster for $40 (including fees). Is this part of the business model? I'd be willing to pay a small premium for your app, but a more than 50% difference in price is too much.
It looked fake to me.
these things can chop your head off (as per a-month-ago-news-story). and yeah, they're very powerful.
A cursory glance around the internet suggests that these things are capable of 20G manoeuvres (!), far in excess of the human maximum of 5-10G (depending on axis of acceleration).

I don't really care which bytecode is the "most popular". I just thought it would be cool to introduce people to some specified bytecode running inside subsystems that you probably didn't think anything about before.
Is it possible that they are amazingly good at not getting caught and controlling leaks. Every now and then they allow them salves to be caught with some crap documents, just to keep up appearances. Just a thought, neither you or I will ever know for sure, unless they develop some serious leaks.
IBM making more powerful Watson supercomputer available for public use
Burke's piece is excellent, in as a far as it goes -- however, expected value is not the only thing one should concern themselves with. Higher moments matter. In particular, in a given situation, when ahead a coach might choose to trade negative expected value for a reduced in variance, and when trailing do trade negative expected value for increased variance. (It looks like his calculator may account for this in some way through win probabilities, but I didn't see an explanation on the site.)

Sanitizing Bitcoin: This Company Wants To Track 'Clean' Bitcoin Accounts
Anyone else starting to feel worn down and disgusted by the behavior of your government? I don't see a lot of change, just a lot of dissection of how bad it is. If the mechanism to change the problem is broken, how do you change the problem?
Agreed, though the one leg analogy would more accurately be hanging from one arm, since the lift is provided from above.
Indeed, less verbose, but also less artistic :)
I think this is exactly what open courseware needs. I will be cheering you on and following your progress closely!

I am not sure if you already have this planned but I would love to see an open curriculum or sorts. Basically a curated list of courses (that have proper video lectures) that I can take to get a degree equivalency.

If for example I wanted to learn everything an undergraduate in business learns at a university, I can take the courses in your list in the order you suggest and get an equivalent education. (These courses should be recordings of actual classes and not dumbed down short videos).

I think this curation of courses will go a long way in how open courseware is perceived.
Essentially ...

"Their plan is to compile a database of the known identities associated with Bitcoin addresses in the hope that Coin Validation will become the one-stop-identity shop for law enforcement when trying to find out who’s doing something nefarious with Bitcoin, while providing a red-flag system for businesses who have customers trying to use Bitcoin that’s associated with illicit use."

Well, here's a quick simulation assuming request servicing follows a Poisson process. The Manipulate function takes a function and generates an interactive version of that function. So in this case it has a graph (list plot) of the simulation, along with a slider to manipulate the number of new requests (arrivals).

If you wanted to be ambitious, you could simulate different servicing distributions, and times. But that might add a whole 2-3 lines of code to the solution.

Ehhh... that sounds like an example of the rocket pendulum fallacy: http://en.wikipedia.org/wiki/Pendulum_rocket_fallacy

Maybe there is something more complicated going on with helicopters that I am not aware of, but a helicopter would not be an inherently stable system due to it "hanging" from the rotor because the direction the rotors are providing thrust changes (all other things being equal), when the helicopter starts to tip one direction.
CourseBuffet actually grew out of my frustration with open courseware. So much content but poorly organized. Too much random.

As for degree equivalency ...stay tuned.
I spent a month in CR last year, for such a small country it puts the UK to shame, I rarely found myself out of 3G coverage, even up in the cloud forest!.

Compare that to my usual South Coast train commute to London where I'm lucky if I get about 25% coverage for a 2 hour journey, and we're supposed to be a G8 nation!

On a side note, I've been working on my startup whilst travelling the states, Hawaiian Islands and backpacking through the Fijian Yasawa Islands and just got back to the UK. I'd highly recommend travelling to anyone looking to get something off the ground, I've always found it a cheaper alternative to paying rent in a fixed locality, there's nothing that beats just speaking to people from different backgrounds about your idea and getting their input.
That is the problem I always have with this argument. It turns into "do you want to have fuck you money and do whatever or keep your baby"? Why not take 3b and start whatever venture you want? Why not 6 different ventures?

Start-up founders don't get rich from salary, they get rich from owning the company (shares.)

Here is a list of people who have employed themselves for one dollar.

http://en.wikipedia.org/wiki/One-dollar_salary

I'm guessing that people like Warren Buffet and Mark Zuckerberg spend surprisingly little money for their day to day living expenses. You don't see these guys driving around super cars, sporting a lot of bling, rolling with an entourage and building the largest mansions they can afford.
If you cause the device you own to operate according to your own will (i.e. the core concept of FOSS) instead of the will of the carrier, there is a strong likelihood it will cause a denial or degradation of service for everyone else.

Verizon has the right to transmit on spectrum allocated to it using consumer devices as its agents. It employs engineers and QA processes to make sure that any device transmitting on its spectrum plays well with others before it is allowed to leave RF-isolated testing facilities.

The public does not and should not have the right to transmit on Verizon's spectrum, even using devices they own which are legally and technically capable, except according to Verizon's carefully vetted programming. If they were able to run their own radio firmware, you'd have the situation described in the parent.

Cellular radios necessarily cannot be open source. The source could be released for inspection and audit, but it cannot be possible or permissible for you to run modified source on "your" radios.
it's true that there are intro sequences in some programs, but due to Cornell Johnson School's unique structure, we did an entire semester of accounting in six weeks; ditto for finance. I'd passed everything I learned in a semester of accounting in 4 days.

agree about coursework not being the point, networking is; but coursework to a point is a factor for many things: career changing, or in my case, burrowing into math and finance so deeply you can hold your own with the best and brightest in the world. (for example you learn when to recognize when you are not the smartest person in the room, so it's time to shut up and let other people teach you)
since all Bitcoin transactions are public and pseudonymity given by opaque addresses is our ONLY financial privacy protection, services like this should be considered a direct and malicious attack on Bitcoin system.
That sounds like a great way to go about it. Personally I'm in a boat where the standard university style of education was rewarding when I had the right professors but largely was not tangential to the growth of my knowledge in most ways. Such is why I ended up attending a programming bootcamp after years of doing it on my own. So services like this really, really appeal to me. I'm just an information/knowledge acquisition junkie and do so at a pace faster than most courses provide.

So, thanks again and I'll be sure to give some input once I have the time to browse around :)
What a coincidence. I just had a conversation with a friend about how FB failed with its Messenger to get the users of Whatsapp & other similar apps. Apparently they know this and are trying to improve it. Same discussion applies to Skype that was never able to make a fast user experience on mobile: every update of Skype on my iPhone seem to slow down the app and make it more crash friendly...
I can resonate with this so much, I travelled CR last year for a month and loved it.

I've just got back from 3 mths travelling the States, Hawaii, Fiji and Aus to do exactly the same, London had too many distractions and whilst the salary was great I knew if I didn't take the plunge to dedicate some time to the startup I too had been talking about for ages then it would never get off the ground. Oh, and seeing beautiful places along the way does wonders for motivation!.
Not to mention simplicity. I suppose it wouldn't matter as much for commercially manufactured rigs, but for hobbyists this thing is a lot more complicated.
When you measure something (e.g. the linked-to "Most active GitHub users by contributions"), and others use it as an incentive (e.g. employers granting interviews) , some people will game the ranking. Here...

top 256 users by contributions
contributions = Pull Requests + opened issues + commits
filtered by > 218 followers

To get and stay on this particular list, you need 240 (= 218 + 10% contingency) followers, which you get by following other projects, not because you're interested in them but because their project members look like they treat following as a favor and reciprocate.

Regarding contributions, which is easiest: making a pull request (which don't need to be accepted), committing code, or opening an issue (which don't need to be closed)? Choose the easiest one, ignore the other two. Then pack as little as possible into every request/issue/commit, creating as many as possible.

There's people out there who do game Github rankings (tho not necessarily this one). It's like quantum physics: whenever you measure something, the thing being measured changes.
Awesome to see another person from Plano West here on HN! Just added you on Linkedin! :)
It seems like once you have a lot of money locked up in equity you'll be able to evade this salary limit by recategorizing your income as investment earnings or some such. So, in practice I doubt this law will be effective.

I'm trying to ask something along the lines of "if the upside was capped at $500k/year". So you could consider that equity, salary, perks etc.

I'm trying to ask whether or not that type of moderate upside would be enough for most people to start startups.
The android one has an iOS 7 aesthetic that feels really odd on Android. Also, Google Hangouts just absorbed actual SMS on Android, so that will be interesting.
I am interested to know how you guys are building this database. At one point we were thinking to provide similar service as part of http://www.merocampus.com We are interested to know if there are API that you are consuming, scrapping websites or adding it manually.
To me a startup isn't about the money, but introducing my idea to the world. The idea of satisfying a need is enough.

That being said, the money is still a great incentive since you're taking a huge financial and personal risk, but you can still live pretty damn well with $500k/year.
Exactly. Given this system, there might actually be more incentive to create startups, as earning potential from a traditional job is limited.
It would be much easier and more effective to just put guns on it.
Well, this is highly tangential, but if you're talking about LaTeX formatting, \epsilon is not generally what you want for the "element of" symbol. Instead, use \in. The biggest difference is that \in is a binary operator and has the appropriate spacing.

Example of the difference: http://i.imgur.com/gwAqirx.png

generated by code:

\textbackslash{}epsilon: $\epsilon$ \\
Example: $x \epsilon \mathbb{R}$

\textbackslash{}in: $\in$ \\
Example: $x \in \mathbb{R}$

If you use \mathbin{\epsilon} instead, you'll get proper binary operator spacing, but you'll still get odd looks from people who are accustomed to \in. Admittedly, the symbol did historically begin as an epsilon, but that notation died off a while ago.
