Without Lisp, or something very like it (and javascript is not good enough), I would not use emacs.

I use emacs as a source navigation and exploration tool, even more than for text editing. Its ability to run code customized to the language and projects I'm working on is far more important than its ability to edit text.

I actually don't like a lot of its text editing functionality, and had to work hard to get things like selection, tab indenting, scrolling etc. to work in a way that didn't drive me up the walls. I had to give up on virtual space, one of the things that stopped me learning it 10 years ago. It's also very hard to record keyboard macros without accidentally cancelling (I tend to press C-g reflexively when I type a wrong shortcut); I use multiple cursors these days instead, even though that is much riskier / harder to use when you can't see the whole buffer / all edit locations on screen at once.

A browser, I don't really need that per se - unless it's linked to library documentation. But it's hard to integrate modern docs without at least understanding HTML, if not HTTP. So I can see the need for a browser implementation.

Hacker News has nothing to do with hacking, you certainly know it. Can you prove the same for that community. Can you? Everyone reading the post is hung up on word hackers. People keep playing the word loose. Even if it is for fun can you deny they can do no harm. Kindly imagine the hypocrisy and the irony of them suggesting how we should manage freedom of expression by mocking our internet safeguard. Come on. I believed in Hacker News being a place where you could discuss with open mind, why is it so hard for other people to accept this point.
It would be easier to write a wrapper that called the real commands. You would have to writer a wrapper for each command, so it's still a lot of work.
There's a combo of things in Java that combine to make this hard to do unfortunately.

There's no concept of reference ownership at all (Because GC makes it unnecessary). Meaning, the syntax doesn't enforce (and in some ways encourages) you to pass and store your references anywhere you want, giving them any lifetime you want. The issue with this is that if you want to insert your own deallocate call, you have to guarantee that every place the reference is passed to never attempts to store this reference. This includes already compiled code, so it already becomes basically impossible to use this optimization when you use any std library functions. When it's not compiled code, then the compiler still has to attempt to do static-analysis on the source code to attempt to figure out if it's going to store this reference somewhere or not. If the static-analysis fails to be conclusive then you have to give-up.
Montessori is built specifically on these principles, and is widely adopted [citation needed ;-)] by parents of gifted kids who struggle with the grind of the regular school systems. (At least, in the western world).

Also, home schooling is growing in popularity in many progressive countries, largely to cater to child-led learning.
I want to know how the kid in the maths circle solved it. Presumably not with Clojure.
Microservices imply distribution and asynchrony, which are both complexity boosters.
In many case you are right.
While Starting with a microservice architecture maybe is a premature optimization,
Microservice are a kind of pattern that fits well when the business logic will grow in complexity and in term of entities/actors number.
At the some time Microservice give you a chance to scale inside the microservice itself without touch any other service

The fundamental problem with China's growth since 2009, is that it has all come courtesy of truly massive amounts of debt.

To generate annualized 7% GDP growth requires five +/- times as much debt as they get in new GDP.

I don't see how an economic model built on growth via accumulating debt faster than any other country in world history has, is a sustainable model. They're courting disaster, and decades of stagnation, just like Japan did.

No, we understand it. It doesn't mean it's a good thing to do, or that we agree with it and won't criticise it.

Also, I am from the East though I grew up in the West, and the attempt to deflect criticism just on the basis of "it's a different society" is disgusting, a hindrance to progress, and frankly quite racist. There is an ongoing campaign in India against the practice of dowry, I guess you also want to argue "Westerners don't understand that India just traditionally has dowry"??
In my book, there is a difference between explicitly asking for help/usage and passing arguments that do not make sense, which triggers the output of help/usage.

I'd really avoid encouraging people to build up strings of html that you simply append to the DOM. This is a great way to run into XSS issues. Although the live DOM is slow,using a DocumentFragment (even if it's completely abstracted away with jQuery) is the right way to make modifications in bulk. The AJAX example is pretty convoluted so I'm not sure what you're proving, but building onto the promise chain seems like a better and much more readable code. Regarding ID selectors, querySelectorAll really minimizes the huge performance gain of id selectors only, and that's exactly what's used on any modern browser when you do a $(".foo")

Show HN: How to Create Meaningful Work. An Interview with Debbie Millman
China's biggest problem, besides the mountains of debt, the record inequality, the broken farming (in which ~600 million people are being kept busy with intentionally inefficient farming practices so they have something to do), the lack of individual freedom, the lack of property rights for farmers, the pollution, and the heated conflicts with most of their neighbors - is probably water. 20% of the world's population, 5% to 6% of the world's fresh water, and falling:

In this particular case it's pretty easy because you know you'll be working with small numbers, so once you establish tighter bounds the work to 'guess and check' will be small.

This 'bound tightening' is the 'ingenuity' required for the problem. There's no general process to achieve that, which is why it requires ingenuity :)

SPOILERS BELOW

To do that you have to notice the common factor in the initial equations.

Let n1, n2, and n3 be number of chickens sold pre-lunch time by each farmer. The initial equations are:

n1*x + (10-n1)*y = 35
n2*x + (16-n2)*y = 35
n3*x + (26-n3)*y = 35

Transforming them a little:

n1 * (x - y) + 10y = 35 ;[1]
n2 * (x - y) + 16y = 35 ;[2]
n3 * (x - y) + 26y = 35 ;[3]

The common factor of (x-y) looks useful; you can establish relationships between n1, n2 and n3 with it:

(n1 - n2) * (x - y) - 6y = 0 ;([1] - [2])
(n1 - n3) * (x - y) - 16y = 0 ;([1] - [3])

(n1 - n2) = 6 * (y / (x - y)) ;[4]
(n1 - n3) = 16 * (y / (x - y)) ;[5]

(n1 - n2) = 3/8 (n1 - n3) ;[6]

If you get there the puzzle is basically solved but for a bit of number crunching - you know n1, n2 and n3 are positive integers, n1 <= 10, so for [6] either n1=n2=n3 (trivial 0-post-lunch-price solution) or n1 - n2 = 3, n1 - n3 = 8. From there you substitute back into [4] and get 3 * (x-y) = 6y, so x = 3y.

You now have simple relations between n1, n2 and n3; as well as between x and y. The remaining step is to tie x or y to one of the n's by substituting into initial equations. For example from [1]:

n1 * 2y + 10y = 35
2y = 35 / (n1 + 5)

y must be integral in pennies; that part is tricker to derive and the simplest solution is to just notice that since n1 >= 0, and n3 >= 0, and n1 = n3 + 8, then 8 <= n1 <= 10, and try 8, 9 and 10 for n1. With n1 = 9, you get y = 1.25. That's the only 'guess and check' part of the problem.

Dump1090 is a clear example of a weekend project that can escape the abandonware route. I wrote it in ~2 weeks during xmas of two years ago, and almost never touched it again if not for a couple of hours more, for lack of time. However the OSS miracle happened, and people continued to use it, fork it, modify it, and have fun. It does not turn like that very often.

It's easy to be confused about the time scale on this kind of work; it's hidden from public view until there's an appropriately newsworthy milestone.

As you point out, this is not a "Eureka!" moment at all; it's a waypoint on an arduous path that has taken decades of work, and will continue on (largely equally slowly) for a long time to come.

The operation discussed in the article was two years ago; it's taken that much time (with intense physical therapy the entire time!) before he has gotten the mobility he has now.

I think things are a bit different in the age of the internet. Seeing into the private lives of others, their quirks and eccentricities, you might find that these traits are fairly common, and even desirable by certain sociocultural groups to be as 'odd' and 'quirky' as possible, as it seems to correlate with success and the capacity to think differently.

Self confidence, I agree is huge, but it can't be faked. It has to actually be known. Sometimes that seems to mean letting your mind go for a loop, coming back again, and realizing you can never know anything while also knowing something.

I just don't really think any of the side effects of being a percieved genius matter as much as the work actually done. Sometimes it means going against the crowd, sometimes it means going with.
Does anyone know the significance of the very specific wording found in the iPhone 6 specs page?:

"FaceTime over cellular uses H.264/H.265" (on US site)

"FaceTime over a mobile network uses H.264/H.265" (on UK site)

Why would they specify "mobile/cellular"? The only thing I could think of was that the extra compression was worth the trade-offs in battery usage in that case due to the limited bandwidth?

Also, it looks like VP9 support may have landed (and been reverted?) into Google's WebRTC codebase in the last week or so:

A couple of points.

1. This is old (2012). There was a major government change in May 2014. The earlier government censored a lot of stuff. Mainly because their performance was below average and they did not want people talking about it.

2. The new government (led by Prime Minister Modi) is very oriented. (Checkout the central attendance system implemented by them in a couple of months: http://attendance.gov.in/). They have been pushing for broadband internet connectivity in villages.

IMHO This is not as applicable today as it was 2 years ago.

All reasonable points, and there is plenty of good reason to be skeptical. On the other hand, Lockheed Martin is one of the largest defense and aerospace contractors out there, with a solid track record for bringing to market sophisticated aerospace solutions. They also made ~$3B in profit last year, so they are probably ok on the money front. At the least they deserve a bit more benefit of the doubt than, say that Italian guy running around claiming cold fusion.

Quite often swathes of the search space can be eliminated or winnowed by using modulo arguments. You can also sometimes fold these problems into smaller spaces by considering equivalence arguments. There are many ad hoc techniques that no one has yet classified or unified, they are scattered across many mathematical disciplines.
The operation itself was two years ago, but then it's taken 2 years of physical therapy (and just healing time...) before it's become clear how successful it was.

So there's no single moment when this becomes "newsworthy"; but I'd assume that as of recently, the patient is walking at a level that's sufficiently impressive for a newscast, and so today's the day.

This would be particularly exciting. Ships, trains and physically large forms of transport (maybe even aircraft/spacecraft?!?) could have fusion reactors built in.

Electric cars charged by cheap power from local, neighbourhood fusion reactors. The power grid is decentralised with reliable baseload power sources, that are clean, reliable (no intermittent problems with weather with renewables) and safe. Power sources can be located where they are needed, whether it's in a basement, on a roof of an urban building or on Mars.
Here's how I solved it mathematically:

Farmer 1 has 10 chickens.
Farmer 2 has 16 chickens.
Farmer 3 has 26 chickens.

Price before lunch: x
Price after lunch: y

# of chickens sold before lunch by farmers 1, 2, 3: a, b, c

Total earned by each farmer: $35

We're told that,

x > y

and can logically deduce that,

a > b > c

because otherwise, the farmers with less chickens would have no chance of making the same amount as the other farmer.*

From this information, we know that:

ax + (10 - a)y = bx + (16 - b)y = cx + (26 - c)y = 35

Let's isolate the first and second farmers here:

ax + (10 - a)y = bx + (16 - b)y
ax - ay + 10y + bx - by + 16y = 0
(a - b)(x - y) = 6y

We can do the same between farmers 1 and 3:

(a - c)(x - y) = 16y

These two formulas yield,

(a - b) = (3 / 8)(a - c)

Since a > b > c,

(a - b) > 0
(a - c) > 0

Since farmer 1 only has 10 chickens,

a ≤ 10

Since you can't sell negative chickens,

b ≥ 0
c ≥ 0

And since the problem isn't very interesting if the farmers are allowed to sell half-chickens, a, b, and c (and the difference between them) are integers.

Given all of this, 0 ≤ (a - b), (a - c) ≤ 10. The only numbers that satisfy this and,

(a - b) = (3 / 8)(a - c)

are,

(a - b) = 3
(a - c) = 8

Since c ≥ 0 and a ≤ 10, we have three triplets to consider:

a = 10: {10, 7, 1}
a = 9: {9, 6, 1}
a = 8: {8, 5, 0}

We can find the relationship between x and y from an earlier equation:

(a - b)(x - y) = 6y
3(x - y) = 6y
3x = 9y
x = 3y

So the farmers reduced their price to a third of the original price during the afternoon. What a deal!

We've got a few equations that look like,

ax + (10 - a)y = 35

Which we can now simplify to,

2ay + 10y = 35

By plugging [10, 9, 8] into the above formula, the only value that gives us a proper dollar amount for y is a = 9.

So...

y = $1.25
x = $4.25

Reading through the G+ comments it looks like someone beat me to it, but I figured I'd share my solution anyway.

*This is assuming that they didn't decide to "sell" their chickens for $0 in the afternoon, which is probably a safe bet.

I find it hard to believe that making desalination a little cheaper, or transport a little less expensive will even come close to counter balancing those sort of percentages.

And even if it did, the relative importance of nations will change. Nations that were important because they had fossil fuels will become less important, and nations that were held back by lack of resources could become more powerful.

Those sorts of changes in power balances would cause a lot of turbulence.
Thank you for your insight into how easy it is to be a rich foreigner in a country where per capita income is roughly 10% of what it is in the US.

China has very very real issues that they haven't addressed in the slightest. They're building tons of real estate that has almost no chance of ever being useful to bump GDP, they're facing domestic unrest in Hong Kong, and they're transitioning into being a more open democratic society. Nobody knows how this is going to work.
I agree, machine learning currently requires huge globs of knowledge to wield. As such it is a tool for an intelligent entity to use, it is not intelligent in it's own right. I disagree with Michael about the correct way forward for machine learning, the problem is not one of piecemeal engineering. If you are spending your time developing algorithms to solve a particular class of problem, you are wasting your time(in terms of pursuit of GAI). The overarching problem needs to tackled, what is the correct framework within which to think about intelligent systems? This is, as mentioned in the article a question of insight - we need the metaphorical apple to fall on some bright sparks head. But if all the bright sparks are fully engaged in chasing the short term problem it might take a long time.

Summerhill: a Radical Approach to Child Rearing is an awesome book and explains how a free school works and why. The Summerhill school has been around for decades and is successful, and probably inspired all of the schools discussed in the article (the book was published in 1960). It optimizes for pyschology --- not pedagogy. This is why it is free: freedom but not license, which to Americans, would be better stated as: an environment without submission and without domination (so, as opposed to an anarchic school, teachers are not submitting to arbitrary demands of children). A healthy degree of assertion develops in this environment. I've seen Sudbury graduates describe this type of school as a generator of entrepreneurs --- they start businesses afterwards and become successful (although from the Summerhill point of view, success is having a happy and flourishing life). I've found many papers across the years, while researching this topic, that, added together, support the idea that learning is affective and pyschology should be an organizing principle of the school.
I've been student at "De Ruimte Soest" and I'm a fair bit more educated about the "movement" than the one who wrote a one-off article pretending it's only a single school!

I think it's a shame that this kind of experimentation is not done in a way that maximises the well being of mankind. Paralysed rats were sucessfully got to walk again at least as early as 2003 (http://www.youtube.com/watch?v=5x8e2qsAVGc) and it would seem to make sense to experiment on the odd human but instead we have to wait decades I think at least partly to cover the regulators arses in case there are any problems. But it would be better for society to have the odd experimental problem than thousands people suffer for years while they muck about with paperwork and the like.

I see from Wikipedia that Geron Corporation have recently submitted 28,000 pages of documents to the FDA for a stem cell related trial so maybe in 2023 or some such we'll be able to do for people what we could do for rats in 2003.
