You can focus on working with JS objects on browser side, and with Scala case classes on server side. Xitrum converts data back and forth for you. APIs for Knockout.js will be improved more in the future.
Twitter also does it as part of the special iOS5-privileged settings panel:

That must have had close Apple review as part of the official iOS/Twitter integration.

The explanation underneath the 'Update Contacts' button is somewhat reasonable, though it may not register with most people that, barring some unlikely fancy indirection, to 'use' email addresses and phone numbers means they're being reported to Twitter's servers.
I'm not sure what you are doing with the above.
Seems like they shouldn't have just focused on chefs, however could be a good market to test before opening up to other areas of interest. Great work!
Sometimes you may use a "number", but you just want ordering properties from it.

You may not want addition and multiplication in such a "number".

This may be the case in numbers used for ranking outcomes, or counting, or optimization. Using infinity in this context does not cause problems.
To be clear, it is indeed your stance that both Bill Gates and Steve Jobs lacked any sort of legitimate skills, talent, or work ethic?
This is evented programming. The event loop is still being used. Fibers give the impression the code is synchronous, but it's still asynchronous behind the scenes.
And, either way, what is the source of the events? Are you really doing them all by hand?

I'm guilty of not having read every word of the paper. But for those who have, perhaps you could indulge my laziness:

Have they ruled out the cause as a buggy or backdoored key generator? Or running down the cause left for some future research?
No, this still supports parallel tasks and evented programing. Fibers let you program in a synchronous manner, but it still be asynchronous behind the scenes.

> He still won't have learned anything without having some reference for the magnitude of the change.

I don't think that's true. This is what the concept of 'effect size' (http://en.wikipedia.org/wiki/Effect_size) was developed for, quantifying how big a divergence we're talking about. I didn't calculate it here because I literally just starting using R a few days ago and I don't know how.

A quick and dirty way is to look at the difference in the 2 means and compare it to what is the 'normal range' (intuitively something like a standard deviation or two), which in this case, my ZQ ranges normally from the mid-80s to the very low 100s (a range of ~20 points), and the difference in ZQ means is 4 points. So that's 1/5 the normal variability - that's nothing to sneeze at! (By a strange coincidence, this is almost the same sort of numbers as for grades in class, so we could analogize: not taking vitamin D at night would improve my sleep grades by one letter. When I was in school, I would not have turned my nose up at such an intervention.)

So, your comment is wrong as stated, I think. But as it happens, I do have something which could serve as your 'positive control': my previous (unblinded non-randomized) experiment with melatonin over half a year or so, which found a shift in mean ZQs of ~8 points. I was really impressed with melatonin when I first started (as have many people been), so to find vitamin D is half as hurtful as melatonin was helpful... I had no plans to take vitamin D in the evening before, but I sure as heck don't now!
And I would add, regarding Alexander, at least, start with his most recent series on The Nature of Order. Then, if you want more, go back and read The Timeless Way of Building, followed by A Pattern Language. But really, his most recent stuff is the most compelling, and the most profound.
I am most definitely not a genius (http://www.gwern.net/Links#iq), so I guess I am just crazy. Oh well - hopefully I'm the entertaining kind of crazy and not the unpleasant kind.

I think this is the natural result of "programming" or "IT" being perceived as a comparatively lucrative career.

I believe it happened in North America, too, just not quite to the same degree.

I first had access to a computer (an Osborne 1) in 1983, at the age of 8. I think it was inevitable from that point that I'd become an electrical engineer or computer scientist. As luck would have it, it turned out to be a reasonably lucrative career choice, but monetary considerations literally never figured into my choice of university program. I had no idea how much an engineer made. I think that most of my contemporaries were similarly-minded. Entering University in 1993, I had never had an email address, and it wasn't until second year that I first saw NCSA Mosaic and this thing walled the World Wide Web.

While I was in university, a revolution quietly, but incredibly rapidly, took place. By the time I graduated in 1998, I was using the web to book travel, buy stuff in online auctions, and my mum was handy at email and finding things on the web.

In my department, a huge shift took place in the incoming demographics - the new frosh were there because Computer Engineering was the hot program to be in. The Faculty halved the Electrical class and doubled the Comp class, and it was noticeable, even years later, when this younger blood graduated and was now in the industry, that many were of a very different mindset to my peers. Far fewer had followed a genuine passion and fascination with computers, and had pursued it for what seemed to be far more pragmatic and material reasons. As one acolyte put it, to my barely-contained amusement, "I'm in software engineering! Bling Bling!"

I mean no disrespect to younger generations. I recognize that there are many fine folks here much younger than those I describe who are as passionate about computer science and engineering as I am, if not more. And there are some gray beards laughing at this young fool who thinks he was the last of a pure breed. But to me that brief period represented a very sudden and very sharp switch in the mentality of those entering the field.

Now take that sudden demographic change, time-shift it a few years to where the global network infrastructure is in place to enable this work to be outsourced just about anywhere, and scale it appropriately considering that this lucrative new field could mean the difference between fabulous (comparative) wealth and a life of poverty. Add an economic crunch that pushed companies to reduce costs, and government initiatives to promote that industry.

That's what India's IT industry has developed - a massive work force that has been suddenly conjured into being and drawing an even lower common denominator than I ever saw at school.

[EDIT: disclaimer- I also mean no disrespect to many very fine Indian engineers and computer scientists; I mean only that the low-end of the spectrum has lowered dramatically]
I'm not sure I agree that the other OEM's would be upset, or that having stock Android is a preference. The other OEMs must feel their custom UI is a value add, so why would they mind competing with a stock UI? As long as MM isn't the sole Nexus OEM (which they wouldn't be, since it's open source), I'm not seeing the issue. Please elaborate if I'm missing something.

They did not rule that out, but when they write things like "the quagmire of vulnerabilities that we waded into, makes it infeasible to properly inform everyone involved", I don't get the sense that "backdoor" is top of mind.
I really think Apple needs to do something here with their next update. For every company that does the right thing by asking permission first, who knows how many are being sneaky.
I can say for a fact that Israel has very little heavy industry of its own, but its tech sector competes with agriculture for #1 sector in the economy and its R&D spending as a percentage of GDP is (IIRC) first in the world.
84% compliance isn't great, but you still see "coerced" overtime in western countries. I picked my wife up at 9:30 on the day before Christmas eve as she had no choice but to finish her work (she works for a law firm and the deadlines if not met can cause a multi-million dollar case to be thrown out). Even though I know it was necessary for her job, I can't agree with employers doing this. The lawyers make 6 figures minimum (her lawyer is a senior partner and gets a share of the company profits so well above 1 mil a year). Yet my wife makes $35,000 and has to bust her ass yet they can't afford to hire anyone else so their workers aren't constantly running on deadlines.

At least my wife's lawyer will not allow her (no arguing) to get paid overtime pay. If she works late, she gets the time off. Some of her coworkers have been paid almost double their wage in overtime pay because the company won't hire them more workers. This is illogical to me. Why pay someone double for 65 hours when you can pay two people for 80 hours.
I don't think anyone has ever had a problem with explicitly asking and allowing users to opt-out. Apps that do that shouldn't be lumped in with the other ones.
If you have to use synchronous code in JavaScript you're doing it wrong.
As can when it happens - I think 4Square was already pretty reasonable, because they only uploaded the address book when you hit "Find my Friends using Contacts" or something like it.

Path, to me, was only particularly bad because they'd upload your contacts every time you signed in.

> There are just too many variables to control for; maybe you're sleeping poorly because you're stressed out rather than because of the Vitamin D pill you happened to take today.

The answer to variables and problems is better setups (more blinding, more randomization, more data), and not counsels of despair. I agree that there's a lot of variability in sleep scores, which is why I run things for as long as I have patience for (in this case, ~43 days; with melatonin, I could run for many months because it wasn't hurting my sleep but helping it).

This is a project from a Physics Education Research group, so the topic is pretty much their bread and butter.

Meh, I eat plenty of lamb, and I know plenty of people who do as well. It's certainly not as popular as beef, but probably mainly because it's much pricier.

Thomas Keller of French Laundry fame (three Michelin star restaurant in Napa) states in his cookbook that he actually prefers to use beef that's been finished on grain. Personally, I like both.

Deer is delicious, if you haven't had it.
No, Titanium doesn't compile to native code. He's using that as shorthand for "Titanium uses JavaScriptCore to implement a bridge that lets your JavaScript call native code". Your JavaScript remains interpreted (and will not be JIT compiled, as in Safari, since your app won't have the JIT entitlement) but in my testing of JSCore it's not generally a bottleneck.
Real thinking and problem solving tends to contradict "constant ... self-development", which often (not necessarily from you but from many) seems to be a code-phrase for "learning every new fad framework that comes along."

Example: web development is so damned faddish that after almost 4 years of its prominence, I have only now settled on picking one damned framework and learning it (Play 2.0 in Scala). I fully expect my newly-acquired "skill" to become obsolete within about a year.

This is not fundamental problem-solving. Hell, I would say that the over-reliance on "frameworks" and "web-applications" to build all modern software on the "thin client" paradigm is itself a fundamental problem that requires more serious thought and problem-solving than most people seem willing to put in.

Hypothesis: Despite the high cost of doing so, backwards compatibility must sometimes be broken.

Considering the potential value of some of those rsa keys, that is a quite minimal investment. This might be an in the wild danger pretty quickly.
So what the researchers did, apparently, was to gather all the RSA public keys they could find (6 million or so) and then calculate the gcds of all pairs of keys.

Apparently not. The number of unique pairings among 6 million is 5,999,999 factorial. Which is a _really_ large number.
To me, this is a great argument in favor of building on top of products like Akka rather than implementing the same functionality yourself. It's pretty clear from Doug Lea's description (http://cs.oswego.edu/pipermail/concurrency-interest/2012-Jan...) that this set of changes would be non-obvious to people who aren't extremely knowledgeable about the internals of Java and the semantics of its memory model.

Alone, work stealing and striped locking are not really new solutions to the problem, but their implementation in JSR166y is really impressive. This is the kind of framework investment that has high leverage, and will make it much easier to write highly performant concurrent code in Java (and related languages) and reduce the need to couple business logic and threading concerns for high performance.
Irrelevant, pedantic, and prescriptivist.
The use of node-fibers is how it's different. Up to you on whether or not you think that makes it better.
Not really - it does make a difference between amateur attackers and professional, but the potential value is high enough that there will probably be plenty of well funded attackers.
I'm not saying I like it, but this isn't synchronous code, which I think the readme does a pretty good job of explaining.
Coroutines don't make the code any less asynchronous it just helps abstract away that detail.
FCC Bars Near-Term Deployment of LightSquared Network
How so? For one thing, there's no way to know if they're even being honest about whether they store the data.
What if your address book was hashed (sha1, bcrypt) and then uploaded? In that case, all that would be uploaded is a list of hashes for the email addresses or phone numbers of people i know.

Then, when another person signs up for an account, it's easy to see who they should suggest they should join, but nowhere is any personal data being stored.

Sounds like it'd work to me?
Those analytical skills stand very well on thier own without the need for further study to justify them.

Calculus and mechanics are part of a well rounded education in the same way as Shakespeare's principle tragedies, or an understanding of the causes and consequences of WWI are.

The fact that these building blocks of knowledge are going to be available in the near future for free to anyone with an internet connection is a modern wonder of the world.
That's the one! It appears to be a scan though, email me if you want the original. There is an accompanying paper describing the process of obtaining and analysing the memory graph (written by a friend and classmate of mine), if your interested am sure I could dig it out.

Regarding your django profiler, I would take a look at some current profilers to see what the standard is. Am on my phone at the moment so don't have much info at hand, but visual studio does it out of the box, and redgate have a decent tool (these are .Net geared - but the principle is the same). Am sure others exist.

I'm not sure how well 3D memory graphs translate to speed profiling visualization, but I hope you find the paper interesting nevertheless.
A lot of the listed services are redundant. I think I could hit 99% of the same functionality at half the cost using just a subset of those products.

Ask HN: how many EC2 instances do you run?
I'm speaking at Cloud Connect in Santa Clara tomorrow morning, giving a talk on how to launch hundreds or even thousands of concurrent EC2 instances and manage them all.

It's based on my experience with a load testing startup I launched a few years back (http://browsermob.com). I thought it might be fun to incorporate some stories from the HN community on how they use EC2.

So please feel free to share what your instance limits are, how many you run concurrently, what kinds of instances you use, whether they are "long running" or you have "spikey" usage, or anything other interesting experiences.

I'll be sure to post my slides to the thread tomorrow afternoon. And if you'd like a hat-tip in the slides, just say so in the comments. Thanks!
Metal, code, flesh: Why we need a 'Rights of the Internet' declaration
I'm saying the framework doesn't have support for parallel tasks within a single request. For example, the case of kicking off two database queries in parallel, then doing something when both are finished. I understand that each request executes in parallel.

It's possible I missed how the framework supports parallel tasks, can you explain? The only thing I saw was wait(), which gives you "series" instead of "parallel". It's true people could still use callbacks/libraries to implement parallel tasks, but then we haven't gained much.

Surprisingly, I found it rather similar to Tokyo actually.

Tokyo, too, has multiple sub centres which are mostly self-sufficient. They are connected by a train running around in a circle and have central hubs where trains depart into the suburbs. Stations are largely accommodated with large bicycle parking lots to facilitate train usage.
However, even though Tokyo is one magnitude bigger than NYC, the transportation fees are fairly high, too.
Also, the Japanese solved the parking space problem, by making it a requirement to have a parking space in order to be able to buy a car.
