...you shouldn't compare yourself with others -- you didn't start in the same place or with the same challenges...

Reminds me of this:

Reb Zusha was laying on his deathbed surrounded by his disciples. He was crying and no one could comfort him. One student asked his Rebbe, "Why do you cry? You were almost as wise as Moses and as kind as Abraham." Reb Zusha answered, "When I pass from this world and appear before the Heavenly Tribunal, they won't ask me, 'Zusha, why weren't you as wise as Moses or as kind as Abraham,' rather, they will ask me, 'Zusha, why weren't you Zusha?' Why didn't I fulfill my potential, why didn't I follow the path that could have been mine."

Study any martial art (preferably one where you can spar) and you'll forever understand the meaning of ego. You show up, do drills/padwork, think you're making progress and then spar someone who beats you up. You do the same thing the next day, and the next, and the next. Eventually you improve and make progress because you're training so hard. But there's always that one guy you can't beat, and that new kid whose far beyond his years in talent. Coach is also now telling you your making mistakes on things you thought you put behind you, and its frustrating the hell out of you that you can't fix it fast enough. Your technique isn't up to par, your cardio is garbage because you had pizza and beer, and your training partners are running circles around you.

That's when you realize you know nothing, that even after these years of training and experience, you feel even less knowledgeable about the art than when you began. Depressed about your progress, you figure you have two options to deal with it: 1) quit... or 2) keep showing up. But by now, you love it too much and its become apart of your life, so quitting isn't an option. All that's left to do then is to continue showing up.

Eventually, the ego is beaten out of you from every failure/loss/disappointment in your daily training. You've tapped out to newer people, younger people, smaller/bigger/"dumber" people that it doesn't even shock you to perform poorly against a total beginner. From here, self-realization naturally guides you into a more focused path for self-improvement. What you want to achieve today is far different from what you thought you'd wanted out of martial arts in the beginning. Telling apart someone who thinks they "know", and someone who truly "knows", is far easier. You'll realize how little you know, as it will humble you. But hopefully you'll come to peace with who you are, and realize what it takes to be where you want to be.

But you don't get paid to be nothing.

So, how do you balance this? I just started a new job. I think a bunch of ways we are doing things is screwed up. However, in all my initial judgements that I have, I'd say about 75% are objective and 25% is just my expert-ego reacting to something being done differently than I'm used to. This self-awareness is good and has served me very well.

But here's the problem: this makes me somewhat hesitant to take up strong positions with the fear that it may be the wrong position that is a result of my expert-ego identity.

At some point, you have to separate the good and the bad that you gain from your identity. My identity as a developer does have useful built up knowledge--lots of which I am paid good money for. I cannot simply let go of that identity. But I can work to be more objective and less fear-driven--so I'm not hating on most everything simply because it does not fit my present mental image of a solution to a problem.

Reminds me of a lecture given on Beginner's Mind that emphasizes the pitfalls of intellectualism:

'Can we look at our lives in such a way? Can we look at all of the aspects of our lives with this mind, just open to see what there is to see? I don't know about you, but I have a hard time doing that. I have a lot of habits of mind"I think most of us do. Children begin to lose that innocent quality after a while, and soon they want to be "the one who knows." We all want to be the one who knows. But if we decide we "know" something, we are not open to other possibilities anymore. And that's a shame. We lose something very vital in our life when it's more important to us to be "one who knows" than it is to be awake to what's happening. We get disappointed because we expect one thing, and it doesn't happen quite like that. Or we think something ought to be like this, and it turns out different. Instead of saying, "Oh, isn't that interesting," we say, "Yuck, not what I thought it would be." Pity. The very nature of beginner's mind is not knowing in a certain way, not being an expert. As Suzuki Roshi said in the prologue to Zen Mind Beginner's Mind, "In the beginner's mind there are many possibilities, in the expert's there are few." As an expert, you've already got it figured out, so you don't need to pay attention to what's happening. Pity.'

Reminded me a little of this quote from The Picture of Dorian Gray:

Lord Henry stroked his pointed brown beard and tapped the toe of his patent-leather boot with a tasselled ebony cane. "How English you are Basil! That is the second time you have made that observation. If one puts forward an idea to a true Englishman -- always a rash thing to do -- he never dreams of considering whether the idea is right or wrong. The only thing he considers of any importance is whether one believes it oneself. Now, the value of an idea has nothing whatsoever to do with the sincerity of the man who expresses it. Indeed, the probabilities are that the more insincere the man is, the more purely intellectual will the idea be, as in that case it will not be coloured by either his wants, his desires, or his prejudices. However, I don't propose to discuss politics, sociology, or metaphysics with you. I like persons better than principles, and I like persons with no principles better than anything else in the world. Tell me more about Mr. Dorian Gray. How often do you see him?"

Looks like a riff on "Keep Your Identity Small":

If people can't think clearly about anything that has become part of their identity, then all other things being equal, the best plan is to let as few things into your identity as possible.

Premise: we are what we think about. Being nothing requires one to think about nothing. It's actually quite a lot of work to think about nothing! The brain is constantly solving problems while awake and while asleep, building up momentum.

Proposal: Instead of expending massive amounts of energy bringing an object of such high inertia to rest, why not just change the inputs you are feeding it to gradually alter its direction? Don't focus on the cessation and extinction of the turning of mind. Focus on feeding the turning of mind solvable or aesthetically pleasurable problems, to decrease the bandwidth occupied by unsolvable\fear based problems.

tldr: I'm not convinced the epicness of ego destruction is necessary for ego transmutation, if that is one's goal.

edit: Well, I just realized my analogy does not hold for all cases. In Physics, if you want to change the direction vector of an object in motion, to the opposite of its present heading, it will require at least as much energy as bringing the object to rest. So focusing on ego destruction could be worth it depending on where you want to go and where you are now.

Additionally, we also know from Physics that all motion is relative, velocity cannot be measured without a frame of reference. I think the Buddhists would argue that cessation of the turning of thought provides this otherwise missing frame of reference, enabling the thought\ego vector to accurately be measured when the turning of thought restarts.

I don't know much Zen, but after the "Zenish" comments in here, I guess lots of HN-ers do, right?

I maybe am a case of "western individuation syndrome", but for me, loosing individuation for protecting myself sounds rather like an oxymoron. Actually, when there's nothing to protect, there nothing to improve, whatever that guy says. And even if you might say that Buchheit didn't suggest to actually dissolve your personality, it very much seems like he did.

Low expectations, realism when faced with your own challenges, sane aggressiveness or indifference, confronting your own prejudices, vices and frustration, are all possible when one's brain is mentally trained, not when you're living with a general sense of "loosing yourself" or when one's dissolving one's ego.

I don't think "letting go of your identity" leads to "a better version of our selves" or "true self improvement", but to a toxic sense of not being who you are.

"But I am nothing, and so I am finally free to be myself." - if you need to be nothing in order to be free, you ARE nothing.

"By returning to zero expectations, by accepting that I am nothing, it is easier to see the truth." - what do zero expectation has to do with nothingness?

"If I were smart, I might be afraid of looking stupid." - that's not being smart, that's being westernly-smart. Change "smart" with "wise" and see if that sentence makes any sense.

Why does someone always preaches extremes to get rid of another? Now I'm being artistically literal: when you say "I am nothing", just loose the "I".

Hey, I had frustrations, I had problems and conquered must of them, partly with indifference, partly with matured ego, partly with higher self-barricades, but not once I thought of dissolving my ego. What the deuce? - I kinda need it! I was learned to fight and gain knowledge, but then I learned that, when fighting something, you actually give it meaning, so then I learned to give up. So this blog post does resonate with my experience at some extent.

Preparing for "He didn't mean to ACTUALLY renounce your personality": it's dangerous to use metaphors or ambiguous expressions when your next paragraph if a plain-life description. Just don't. Use "lower your expectations" instead of "be nothing". This is logic/biologic-ally wrong. You can't be nothing, but you can't be all of it, neither, so, in the mediocrity principle, just be something, because you already are (how's that for metaphoric?).

Love the post, but nothing? I say adopt 2 or more senses of self, and get really good at using them at the right time.

I think moving beyond an ego-based sense of self is the best way to think rationally and accomplish a goal. In fact, the biggest benefit is probably being able to rationally understand other people's point of view without a sense of self clouding up your interpretation. But, for me at least, it has not been pragmatic to abandon a sense of self at all times.

For instance, it is much easier for me to relate to my grandmother with a stronger sense of self - or at least project a persona that gives that appearance. You can't really like people or things (in the most basis sense) without ego. Nor, can you fully extend emotional empathy in the purist sense when you have no sense of self. With no ego there are many professional environments that will simply drain your energy - even if you have a decent persona for relating emotionally with others.

For me, the better answer has been to look at my self (more specifically my brain) as a library of different selfs. Yes, I am nothing, but I must at least be a controller that responds to my environment with the most relevant sense of self at any point in time. I would suggest there is an evolution of self beyond nothing.

An oversimplification

suffering = your self image vs perception of reality self

The argument goes that man is a prisoner of his self image. This self image is a mixture of his desires, wants, tastes, hopes, fears.... This can be seen as a self image that arises out of conditioning by the society and self. You are like a frog in the well and imagine the well to be the universe. You are limited and shaped by the well. How can one know of what the possibilities are unless they ascend from their own intellectual/egotistical/scoietal wells or the well of self image?

On the other hand, I have noticed that rejection of natural tendencies leads to suffering as well. No matter how hard we try the self will never be a blank tape. When you reject the self image your self image becomes "Im he/she who rejects self image imposed on me". So now you are straight back where you started with a brand new self image, only this time you are more observant of your flaws(tendencies of self). So there is still suffering here.

Let me oversimplify again
the frog = Neo in the matrix,
Ignorance is bliss = Cipher in the matrix

What a wonderfully thought-provoking and inspiring piece. Thanks, Paul, for sharing it.

In a similar vein, from David Foster Wallace's 2005 commencement address at Kenyon College:

"If you worship money and things -- if they are where you tap real meaning in life -- then you will never have enough. Never feel you have enough. It's the truth. Worship your own body and beauty and sexual allure and you will always feel ugly, and when time and age start showing, you will die a million deaths before they finally plant you.... Worship power -- you will feel weak and afraid, and you will need ever more power over others to keep the fear at bay. Worship your intellect, being seen as smart -- you will end up feeling stupid, a fraud, always on the verge of being found out. And so on."

A recurring theme from great thinkers (perhaps mainly more in the East, though) over the ages. Glad to see it finding an audience on HN.

This excerpt from Rumi seems apt:

  "Knock, And He'll open the door
Vanish, And He'll make you shine like the sun
Fall, And He'll raise you to the heavens
Become nothing, And He'll turn you into everything."

My take on this line of thought is that as long as you consider yourself as being a "someone" or "having a self" you are always in conflict with other selves and only if you become nothing you remove the inherent conflict.

I think there is a fine line you need to tread. I agree with what paul has to say but sometimes what we care about is what drives us.

For the longest time i worked as a consultant but i never cared. When someone said to me so what do you do, i just said i work with computers, my rank didnt matter to me, my role , my status nothing. I wouldn't come to work in a suite or tie or even a shirt (i came in just a t-shirt and jeans) and it was very weird to many who were watching. I guess cause they cared and wondered why i didnt ...

They would say , "your a consultant, for a big4 how can you wear those clothes, cause i personally cant".

I would respond by saying, well i dont care , just wanna make sure customer is happy regardless of what my official role is, that way i could do my work , not have to redo things and then go home. Also one of the important things i think is i detached myself from being a consultant, i was nothing, not a manager, a consultant, a senior consultant , who has certain things attached to them so i felt free and just wore what i wanted with the one rule that the customer needs to be happy.

When i found out that i could get away with that i experimented with a few other things too, like if i was tired during lunch i would sleep on the park bench if it was a nice sunny day. I stopped thinking hey im a professional and cant be seen sleeping on a park bench cause thats what bums do and once i got over it and i thought , hey who cares, it was easy and i would come back to the office invigorated cause of a 20-30 minute quick nap :)

However the caveat is when you CARE enough about say programming . If you start to tell yourself you dont care anymore you loose a certain desire which if you care about it, isnt very good. if you keep telling yourself hey i am a programmer then that comes with certain things such as , writing code, being half decent at math, being logical etc etc and being good at those things isnt a bad thing.

So i think i get what paul is saying when he says "i am nothing" but i think you cant apply that to things you care about cause it will cause you to not care. But applying that way of thinking to things what you might care about but deep down know its just for perception or is kinda silly or even not really important has some surprisingly good results :)

This is a major component of Christianity. (I'm not preaching here) I thought it was interesting that the non religious world is figuring out things that have been core teachings for the last 2800 years.

In the christian world, it is called "taking yourself off the throne and putting another entity on it". The entity that gets put on it is variable, but the constant is that you are not on it.

It seems to me quite difficult to follow the philosophy described in this essay. It also seems to me an undesirable life, though I can see why a person would want it.

This isn't relevant to the actual message of the post, but something that caught my eye was in the paragraph about thinking you are "too X to be Y". Most of them make sense, and I can understand people thinking the Y because of feeling the X. Except these two:

  too effeminate to be straight

too smart to be kind

Am I being foolish or do those two not fit? I can imagine someone thinking "I'm too sensitive, that's not how a man should be", I can't imagine someone thinking "I'm effeminate, I guess I can't be straight after all".

In other words, "apple is being eaten by you just as much as you are eating the apple". It's not so much that you have chosen to eat the apple, as much as the apple chose to hit the receptors in your brain that will make you eat it. But it's all ridiculous: you and apple are one harmonious system.

Awesome essay from Paul, very insightful.

This mindset is good at not only helping yourself become yourself, but placing the best people in your life.

If you spend your entire life trying to please everyone you meet, decide who you should be friends with and who you shouldn't, and become a person that others will like more, you will ultimately not make friends who you would have by just being yourself. And those are the friends you want most.

Perhaps even worse, you could waste endless amounts of time on people who you think you should be friends with or have in your life, but really shouldn't. Sooner or later, the relationships with these people that you built on the foundation of some artificial idea of yourself will crumble. If you know that you are nothing, then become yourself, you will be surprised how many amazing friends you will find in your life.

Here's the thing, though: as long as others see themselves according to some paradigm, they will likely see you in relation to them and cast you in some social role.

In social interactions, we assume some identity to relate with those around us. Inevitably, those interactions (if we're receptive and respecting of who we interact with) will affect our own thoughts, including (sometimes) our sense of self.

No man's an island, and no man's nothing so long as he lives in a society. Saying "I am nothing" is just as bad as saying "I am X"

On the other hand, he talks about "returning to zero expectations" and being "nothing."

I conclude that Paul wants to be a better nothing. Or possibly that he is slowly decaying. I'm not sure you can be nothing and also have a standard for getting better.

I didn't find it that harsh. He was direct and took pains not to ridicule a thirteen year-old for making an entirely age-appropriate mistake in measuring the results. Instead, he asked the perfectly valid question of how this becomes news without critical thought.

In that, the critique seemed hopelessly ignorant of how the news works. Why should science fair projects be treated any differently than crime, the personal lives of celebrities, politics, or economics? News outlets publish first and ask questions later or not at all. They have gone to court to defend their right to publish things they know to be false.

How did a confused science project become international news? Why, the same way that almost any overnight sensation becomes international news, by being digestible, by being something people want to be true, by appealing to their preconceived biases.

A commenter pointed out that this is the value of a peer-review process. And indeed, this result was published without peer review. So who is the fool here? The journalist for publishing without review? Or the reader who knowingly accepts the result despite it being published without peer review and/or corroboration?

Coming back to this almost eight hours later, I ask: What is the problem here? On HN, we upvote articles that are interesting. My idea of a downvote is an article where I felt I lost IQ for reading it. In the case of the kid's mistaken result, is there any question his research and theory were interesting? Does anyone honestly feel stupider for having read about it and considered the possibility that he was correct?

Quite honestly, almost everything that makes it to the front page of HN is wrong. We talk about software development, startups, muse about whether Apple is brilliant or is lucky enough to have lame competition, argue about Haskell and Erlang... All stuff that is non-empirical and therefore unfalsifiable.

How does that stuff get a free pass to be on the front page of HN without peer-reviewed research backing it up? I'll tell you how: We're smart enough to know that all of that stuff is probably at least partly wrong, but if there's something in there that makes us smarter, it's worth reading and upvoting and discussing.

If the kid's ideas had in them just one thing that made us smarter for having thought about it... That's a win, that's worth upvoting and repeating. Why wait for peer review? As long as nobody ran out and dropped a million bucks on manufacturing solar arrays, what's the harm? If anything is wrong with an article, a day or so later, all of the flaws will be corrected. And thats exactly what has happened here.

Thinking about this, I don't see a problem with the “blogosphere” or with HN upvoting and tweeting and repeating the original article. Thank goodness we don't put everything through a peer-review first. I'd say things are working just fine, and I encourage every other thirteen year-old kid to experiment and publish.

No harm, no foul. There's nothing in there that's more wrong than anything I've ever said in a blog post or a comment, it's just easier to prove where empirical science is concerned. But even when they're wrong, my posts are useful if they help people think, and I suspect his post is useful for the same reason.

This doesn't address what I thought was the insight, which is about finding optimal placement and facing for stationary solar panels when the light source (the sun) is not stationary. Neither throughout the day or through out the year.

It doesn't seem impossible that some placements are better than all-in-one-direction, especially over time, and that's what I thought the experiment was about.

Am I misunderstanding something basic?

EDIT:

Going back and reading the kid's writeup at http://www.amnh.org/nationalcenter/youngnaturalistawards/201... shows some interesting details.

He's not using voltage as a proxy for power, he's using it as a proxy for "sunlight collected". There's two voltage graphs on that page that are machine drawn, not hand drawn. The point of interest in the two graphs is that the Standard graph has narrower peaks of voltage, whereas the Tree graph is broader. This represents the idea that the Tree was generating electricity over a longer period of time. NOT that it was generating more power, but that it was collecting sunlight for a longer period.

The 20% and 50% pie charts indicate this same idea. The percentages are hours, not watts or volts. 12.5 hours vs 8 hours in one timeframe, 13.5 vs 11 in another. Hours. Not volts, not watts. Time, not power.

And I'm particularly happy that the author took great care to not target the boy. He should be encouraged to continue this kind of scientific pursuit and not be dissuaded by mistakes in the research. In fact this is a good example of how peer-reviewed research actually functions. That said, I feel the MSM only does him a disservice by misrepresenting the implications of his project as something more than it might be.

He points out that voltage in solar cells is essentially boolean. Ok. That means that the kid has shown a way to orient the cells so they get sunlight for a longer period of time. If evolution is anything to go by, his approach likely reveals a local minima for maximizing the time that sunlight is collected.

Is that worthless? No, it is not. It may well explain why trees orient their leaves the way they do, and there could well be practical applications. If your solar array produces more than the peak power you need but the cost and energy loss of storing the power are significant, you may well want to use a pattern like this that mimics what trees do.

What impresses me is that the kid noticed something in nature he hadn't noticed before, read up on it to see what was known about this pattern, and then went out and measured to see whether what he had read was accurate. Once he had verified what he read, he then figured out how that knowledge might be applied. In doing so, he discovered something that, while obvious in hindsight, is not something that would necessarily have occurred to someone trying to figure out how to maximize the time for solar panels to deliver energy. I think the kudos are appropriate, even if the stories are misleading.

An important point here is that in any news story about something that you know a lot about, there are always errors. Always. We should all keep that in mind when we read or watch or listen to the news.

I wonder, if this idea come from a someone older without any real experience or qualifications in solar would it have been fact checked a little better before it ended up everywhere?

I would want to encourage young people as much as possible, it's just that some of the things you heard about are only considered impressive when those doing the story have factored age into it. If the person was say 30 it wouldn't even be a story.

Absent an explanation of why the author chose to delete this article, I can't bring myself to find it credible. It might be right, or it might be very wrong in a non-obvious way that the author finally realized, causing him to delete it. There are other reasons it might have been deleted, but I have no good way to judge.

Given that, I don't think it really adds anything to the overall debate.

It is not ridiculing those who fail that we advance science, it is about thinking differently even if we fail, for we learn and improve and someday we will succeed.

What if we use solar cells on one side of the leaf and mirrors on the other so they can reflect sunlight when the leaf looks east and the sun is going down west?

What if we use a sphere shaped cell? like a mango tree? or a cone shaped cell? like a pine tree?

What if we put solar trees on every sidewalk, even if they produce less energy, but are more ergonomic and easier to accomodate in our daily lives?

What if we sprinkle some water on that solar tree? What if we make it taller? wider?

Go on kid, continue your experiments, listen to those who give you sound advice, ignore the ones who only add noise to the harmonious melody of nature and science.

This post reads to me as if the person took personal offense to Aidan getting "undeserved" recognition. He claims to be angry at the journalists and scientists who didn't do their research before jumping to the conclusion that he had created something amazing, but the tone is just unnecessary.

> Some poor 13-year-old kid is all over the news

"poor 13-year-old" is hardly the words I use to describe a kid who got a bunch of press because they conducted an interesting science experiment, no matter how incorrect the end results of that experiment were.

> blindly parrot the words of this very misinformed (not to blame him, he's an unguided 13 year old) kid.

If a 45 year old scientist posted the results of an experiment that challenged the furthest reach of their abilities, and some scientists with more information or a different perspective explained why the experiment was conducted incorrectly or why the results were inaccurate, nobody would call the original person "very misinformed" or "unguided".

There are just a lot more ways to tell a 13 year old conducting solar panel experiments using concepts beyond most adults abilities the ways in which they could improve their experiment. The last thing you need to call a kid doing this kind of work is "very misinformed".

Trees don't rotate to face the sun.
In order to have an optimal angle throughout the whole day, it would have to keep facing the sun, i.e. rotate.

I think the point here is that Aidan's system has no moving parts and does not track the sun. If you accumulate the total energy produced by the array over a period of one year in, say, capacitors, then I am not certain at all that his tree configuration would not be better than a fixed array of cells.

Of course, the fact that the picture in his paper showed a bright white wall just besides his experimental setup removed credibility to the whole thing.

But this prevents no one from repeating the experiment with better control over the variables and who knows...

A bigger point here is how we all mistook the results. There is always a struggle between extreme peer review, which leads to insularity, and going by the net real impact- 'don't publish, build'. In the latter approach, the winner often forgets whose shoulders he stands on. In the former, you cannot stand too high from your peers' shoulders, and there are few real winners- 'everybody is great, everybody wins /s'.

Insert single characters: Press 's' in normal mode and the next character you type will be inserted at the cursor and put you back in normal. Press 'S' (Capital S or shift+s) and the character will be inserted after the cursor like 'a' append. This is also repeatable, so you can insert a character and then do '5.' to insert it 5 times, still leaving you in normal mode afterwards. Being repeatable is the reasoning I read for it being a function. I picked this up from the Vim wikia site awhile ago.

    " Insert single char (repeatable)
function! RepeatChar(char, count)
return repeat(a:char, a:count)
endfunction
nnoremap <silent> s :<C-U>exec "normal i".RepeatChar(nr2char(getchar()), v:count1)<CR>
nnoremap <silent> S :<C-U>exec "normal a".RepeatChar(nr2char(getchar()), v:count1)<CR>


Press 'F5' to run the file you're editing, assuming it has a shebang.

    " Run current file if it has a shebang
function! <SID>CallInterpreter()
if match(getline(1), '^\#!') == 0
let l:interpreter = getline(1)[2:]
exec ("!".l:interpreter." %:p")
else
echohl ErrorMsg | echo "Err: No shebang present in file, canceling execution" | echohl None
endif
endfun
map <F5> :call <SID>CallInterpreter()<CR>


I don't actually use this one a lot, but it can be handy. F10 to switch between the line numbering modes, in Vim versions that have relative line numbering (>= 7.3)

This is one of my favorite bits from my .vimrc. It lets you use !find with location list:

  function! g:Find(...)
let subexpr = 'substitute(v:val, ".*", "\"&\" 0: found", "")'
let found = join(map(split(system('find ' . join(a:000, ' ')), '\n'), subexpr), "\n")
exec 'lgete "' fnameescape(found) '" | lop'
endfunction

command! -nargs=+ Find call g:Find(<f-args>)

The :Find command above passes its arguments to `find`.

I use splits heavily, and these mappings for navigating and resizing splits are indispensable:

  nnoremap <C-K> <C-W>k
nnoremap <C-J> <C-W>j
nnoremap <C-H> <C-W>h
nnoremap <C-L> <C-W>l

Not to take anything away from a really nice contribution by Twitter's team, but know that stuff like this in tens of different variations are available for tens of dollars at sites like ThemeForest.

A typical "admin" theme has some variant of the 960 grid, nice forms and buttons, drop-down navs, tabs, and accordions, and multiple layouts.

The templates won't be as well documented as this one, and they'll be more brittle and probably more poorly coded... but they'll only take an hour or two of additional work to (say) Hamlize and bring into your Rails project. They'll look more distinctive than Bootstrap. They'll have better browser compatibility.

Unless you're crazy enough to be selling web apps to web developers, no customer of yours is ever going to know or care which of these things you started out with.

Or, use Bootstrap; it's really nice. I'm just saying you have lots of good options.

This is absolutely interesting and amazing to see. There's a lot of good elements and style in here. I think this is a great effort and movement forward to help bring a "standard UI" library to the web. I think there's a good use case of websites starting to have a more "locked in" UI/Look & Feel. I'm not convinced by this notion but it's something I've been thinking about lately.

Either way, this is a great library for bootstrapping your web-app.

I do have some qualms though, but this is due to the limitation of CSS. You really should start practicing separation of content from presentation. It's great to see them leverage LESS but I'd like to see this integrated with SASS/Compass.

Classes and ids should describe the data that you are marking up, and not the structure of the view. It is really hard to continue to work with something like this. It increases the number of classes on each element and causes the developer and designer to fight over which classes go where. Now we have separate classes for style and functionality.

If we describe the data then it is easy to describe the view of that data in different ways, and with the same html.

In my view, the biggest drawback of the evented approach is that logically sychronous code involving IO becomes very low level spaghetti code. E.g:

becomes:

  read(source, function(input) {
write(process(input), function(success) {
log(success)

YES. THANK YOU. I was just ranting about this elsewhere. People go "threads are evil" with vague rationales about getting locks right and such, and insist we all use separate heavyweight processes. It's ridiculous.

Selection of sane data structures and communication channels can get you virtually all of the safety and ease of separate processes WITH the performance benefits of a shared memory space.

It reminds me of people that criticize C++ for allowing memory leaks. There as here, simply selecting the right primitives and development strategy in advance make the problem simply disappear.

The important question is: how can humans correctly write concurrent code?

We think of "threads" as one of the options. The thing is that we've mostly been using threads with locks (e.g. Java), and slide #3 points out where we have gone wrong:

  Drawbacks of threads
...
Drawbacks of events
...
Actually drawbacks of locks and top-level select loops!

In fact, it is "locks" that humans have trouble with.

Note the title of the presentation - Threads without Locks - suggesting another option. (as others have noted, this presentation describes Go, and I personally believe this is why Go will do well)

Threads tend to be event driven anyway. If one used, say ObjecTime back in the Olden Days, one could actually configure which FSMs had their own O/S thread and which were shared on a single thread.

This being said, event-driven as a design choice has much to recommend it.

Ok, I've been a procedural programmer for years. I struggle even with OO. Where's my easy bridge to Functional? Where's the killer "here's the trick, the secret, the leap"?

Because I have to say, for all the "functional will save you" mantras, I keep finding a procedural approach gets the problem solved. Are my problems too simple? Not scale issues? Perhaps. And clearly, I am not trained in anything other than intro Lisp and Hadoop, so I haven't had the deep dive indoctrination others appear to have had.

But as each new computing metaphor comes, we find ways to make it easy for folks trained in older metaphors to come over. Other than Scala, I've found few bridges that are trying to help procedural and OO lang folks adopt functional. It's no-one's fault, I guess, other than new folks are trained in it, and older folks aren't.

But I'll keep looking for that bridge, that shining one thing that will make me go "aahhha, I see" and not "one of these books will explain how passing this function through this multi-nested other function is better than just making a loop".

Because after all these articles, I know functional is great. I just feel bad that I haven't been able to make it great for me... yet.

The thing that got me really interested in learning Haskell was the realization that something like 90% of the nasty bugs that I fixed in production over the years would be have been impossible in a pure functional language.

The thing that slows me down is the prospect of actually getting paid to write Haskell, and my doubts about it's ultimate suitability for iterate-quickly, fail-fast software world.

But reading this article reinvigorates me. Pure functional programming may be much harder, but its rigor allows for more powerful abstractions. Grokking those abstractions is no doubt useful regardless of what language you're using.

I love Erlang so much I haven't yet gotten around to learning another functional language. (still growing with erlang).

I learned it reading Armstrong's book from Pragmatic Programmers. It was a joy. I'm also reading the OReilly book, and it seems good as well, though I can't tell how it would be if I didn't know the language already. As for the titles-- one is Programming Erlang, and the other is Erlang Programming!

I see that some people are saying that functional programming is more powerful than OOP. I disagree with that.

I do not think one is less than the other. Actually there is a mathematical argument why one is not less than the other. To me functional programming is "what does what I'm trying to describe do?". In object oriented programming it's "what are the properties of the thing I'm trying to describe?". In functional programming I describe the interactions directly and in OOP the interactions come about from how I have described the objects. Done properly, they are both about interactions, it is just a difference of what you focus on.

It has been shown that classes of OOP can be modelled for the most part as co-algebras. This means that objects are a mathematical dual to algebraic types of functional programming. The reason why functional programming is important is that some things are easier to express in a dual space. This means that many things that are hard in OOP are trivial in functional languages. But the reverse is also true. This is why it is important to not drop one for the other.

The real advantage IMO in functional programming is that these languages tend to be developed with stronger mathematical foundations. Hence programming in them tends to encourage people to be principled and rigorous (at least in theory). It is very likely that if you study the subject you will naturally come to be interested in why monads are only one particular type of functor, that polymorphic functions are well described as natural transformations or try to wrap your head around mechanically generating dynamic algorithms in terms of hylomorphisms. The more mathematical nature also makes it less magical and rickety to the self taught programmer (such as myself). That I think is the real advantage. But there is nothing inherent in OOP that stops it from also being built from more rigorous foundations. Such things will come to matter more with increasing concerns in security.

I think functional programmers sleep on the power of coalgebras. In fact his example of google map reduce is completely ignorant of the fact that the real hero in MapReduce tm is unfold not reduce.

I have a pet theory that the fact that algorithms are written in dual styles is why experienced OOP people find functional programming so hard. They literally have to reverse their style of thinking. This takes a lot of energy. Just because it takes place in your head doesn't make it any less physical than trying to roll a boulder uphill or get a wagon wheel out of a rut.

I'd really love to hear PG defend this line: "But with Lisp our development cycle was so fast that we could sometimes duplicate a new feature within a day or two of a competitor announcing it in a press release. By the time journalists covering the press release got round to calling us, we would have the new feature too."

I'd really love to see the code for something that one would do in a day or two in Lisp, but would be much longer in another language. I don't suspect there exists a wide class of such things -- I suspect the features tend to look like embedding Lisp compilers.

This is the lie that every functional programmer has perpetuated for the last 50 years since the dawn of Lisp - that somehow, automagically, productivity or effectiveness of programmers increase with the use of functional languages.

It's the biggest lie in the programming world, and it was designed to make the uber-geeks of this world, those people that you walk around the block just to avoid saying hello to because you know they are deeply and profoundly anti-social, feel good about themselves, to feel special, as though they have the "upper hand" that other normal people who deliberately choose other languages over purely functional ones.

There is value in learning how to think recursively, but a lot of programming, especially systems programming doesn't need to have its for loops transformed into recursive functions, or its addition operators into primitive recursive functions.

I am sick and tired of people expounding on the alleged efficacy and efficiency of functional languages and I wish they would just STFU once and for all and go back to their porn intermezzos between their functional programming spurts.

I still think that the strongest argument for pseudonyms is that a system that doesn't handle them is Wrong, in the same way that "everything can be losslessly converted to ASCII" is wrong, or "an accurate map of a geographical area can be drawn on a flat surface" is wrong. Pseudonyms aren't a feature you can decide whether to support or not, they're part of the problem that you're trying to solve.

I live in central Japan's manufacturing hub. If you ever come visit me, and really want to return depressed, I'll arrange for us to take a tour of the company which produces most of the world's cell phone camera gaskets. (A little ring of rubber around the cell phone lens.) You very well might have one in the Japanese cellphone which came in the Chinese paper box and got stamped "Made in China" that you have in your pocket.

Every day, a couple hundred workers report to the factory. The most labor-intensive step in the process is taking a sheet of approximately 1,000 gaskets, manually removing them with a tweezer, inspecting them under a jeweler's loupe, and depositing the passes into the waiting outgoing package. When you fill it, it gets wheeled away for shipping. Your quota is 1,000 passed gaskets per hour, for which you are paid approximately 1,000 yen (at least, that was the pre-crash wage), or about $13 at today's prices.

When you say "We want our manufacturing jobs back", this is the kind of job you really want. It is easily the worst legal job I've heard of in a first-world nation. There's also practically a clock on the wall saying Time Until Robotic Arms Are Sensitive Enough To Do This Without Damaging An Unacceptable Portion Of Gaskets.

One reason that (pre-crash, anyhow) this neighborhood had a lot of immigrants is that the typical worker at this sort of factory 30~50 years ago was a Japanese woman in her twenties and that these days the job is a job Japanese women mostly won't do.

Yeah, lack of infrastructure. In my opinion that's true of every facet of the worthwhile goals of our national (U.S.) life, from good healthcare to cutting edge science to excellence in education.

Somewhere along the way that same short-sightedness the author discusses of mis-emphasizing short-term profit (e.g. "tax cuts") started bankrupting our future. Now we're reaping what we sowed. Practically every revolutionary advantage we gained over the last century at least (e.g., public health initiatives and sanitation, public education in the early 20th century; establishment of publicly funded research; the space program, the internet) were all collectively funded programs by government - by us - the collective will of a people not held hostage by short-sighted "anti-government" rhetoric.

I hate this "America is losing greatness from losing manufacturing" argument. Our citizens don't want to work in manufacturing, and the Chinese (and other foreign citizens) are willing to do it for less. Sure, why not, they deserve it!

The world would improve if we stopped thinking in a "us-vs-them" nationalist way. Think in a global way!:

* We're helping Chinese farmers get out of abject poverty into a slightly better situation.

* We're improving their economy

* We're making cheaper goods for Americans & other developed countries, which means that it will be accessible to poorer people (which is a good thing!)

* The company will gain more profit and be able to make more innovative toys for us!

If we want to go down the nationalist root, then why don't we just outlaw imports all together? Or at least pass some protectionist tariffs?

If we did that, with the foolish misconception that it would help our economy, we would goad other countries into passing tariffs, and the whole world economy would hurt.

I think it is important to keep in mind that manufacturing output has actually been increasing over the last 50 years. It is just manufacturing employment that has fallen. That is a natural consequence of becoming more productive.
See: http://mercatus.org/publication/us-manufacturing-output-vs-j

The Forbes author is arguing that it is hard to innovate when all the manufacturing expertise leaves. To support this he argues that some Kindle parts are made in China, others Taiwan, others South Korea. To me this is evidence that innovation occurs at a decentralized level. Innovation occurs when companies specialize and focus on a better battery, or screen, or lens instead of a better device. Most people on HN seem to believe that small decentralized start-ups are more innovative than bigger companies. Why is decentralization good for software innovation, but bad for hardware innovation?

David Ricardo made an underappreciated contribution to the prosperity of all humankind when he developed the explanation of the law of comparative advantage not quite 200 years ago. As long as manufacturers want to have large markets, they will sell to people who desire manufactured goods. And as long as we (whoever "we" are) have something to trade with the manufacturers, we will not lack for any manufactured good that has been invented. The United States of America is full of affordable Kindles, and people with all kinds of occupations can afford to buy Kindles if they like Kindles.

Technically, Amazon could make the Kindle in the USA out of parts shipped in from various Asian countries even though it could not make each of those components in the USA as well.

But then, what really could be made entirely in one country? Especially when you consider each component, the raw materials, the machinery used, and so on down the line for each of those.

I don't necessarily disagree with the author that there is value to keeping a process "in house" which needs to be including in any cost savings calculations and that American companies are prone to discounting that value when making decisions. But at some point some components or steps in the manufacturing process might be necessary or optimal to leave in the hands of others whether foreign or domestic.

"An exception is Apple [AAPL], which “has been able to preserve a first-rate design capability in the States so far by remaining deeply involved in the selection of components, in industrial design, in software development, and in the articulation of the concept of its products and how they address users' needs.”"

This guy is very confused. Other US-based companies selling hardware operate in this same way. To boot, he never shows that anything listed here for Apple WASN'T done in the US for the Kindle. The same laundry list of components he describes for the Kindle goes for every Apple product, every Motorola product, every Xbox 360, etc. Yet the design and software is usually done in the same way Apple does.

Bubble or not, since the money are available, perhaps this is a good time to start building companies that solve real problems. Not that Groupon isn't cool, but the unfortunate thing is that gamification startups or group deals or 4sqr+photos+nonsense are popular, and the money is being thrown their way. Investing in those companies makes financial sense, but it would be great if more health-care or education related startups were not just funded, but also bragged about. In a long run, they could have a great impact on the society at large, even if they don't make investors into bagillionairs.

If the current crop of start ups has a decent percentage of companies becoming profitable and remaining in business 5-10 years down the line, it's boom.

This is even more significant in that unlike other URL shortners such as bit.ly, t.co won't show you statistics (at least for free).

So if you get a bunch of t.co traffic and you don't want to pay Twitter for statistics, the only way that I've seen that you can understand how you are getting traffic is to search for keywords relevant to your site and hope to find a tweet that includes the t.co link that you saw in your logs. You usually can't even search for the t.co link itself (unless it appears in the text of the tweet.)

Very annoying for people who want to study their server logs without paying extra money, but a great way for Twitter to monetize. (Even if users decide to include a bit.ly link to get free statistics within a tweet, it will still be hard to track down as explained above.)

As annoying as this is if you're writing something that depends on t.co using proper HTTP status codes, it's really fantastic for users of Twitter.

It masks the referer header, which protects my privacy without breaking sites that rely on the referer header.

Secondly, and much more importantly, it gets rid of privacy-destroying URL shorteners like bit.ly that give the posters statistics on their tweets.

It might be a tiny annoyance to some developers, but the privacy gains are fantastic.

I noticed long ago that none of Twitter's redirects had the proper referrer listed, and it really is annoying. There's no way to parse a log and know how many people clicked on a link from Twitter unless I use another landing page just for Twitter shares which is a bit silly. I don't see why Twitter is doing that.

Correct me if I'm wrong but this means the referer will show up as t.co, meaning that you can just as easily track twitter referals, just by looking for t.co rather than twitter.com?

The downside is that you can't see which twitter URL it came from, but in my experience that was rarely useful as so often it came from users' home pages. And the upside is that it will show a t.co referal for non-web twitter clients, e.g. mobile apps.

You can pick at Marc's words as much as you like, but having heard his visions back in '95 when Netscape was big, he's a big picture guy and is seeing the forest for the trees.

Consider the following:

- In this decade and the last, software engineer consistently ranks in the top ten best jobs

- During the financial crash, software engineers enjoyed the least turmoil and the quickest recovery compared to almost all other sectors

- Software is mission critical to almost every business in the world now, regardless of sector

- Our jobs tend to have the highest pay among the majority of jobs (again, top ten)

I'm with Marc. I'll double down on software right now...it's not going away.

Add to these the recent announcement of Foxconn to install 1000000 robots. Now software will even be eating up sweatshops. Unfortunately, the rest of the economy is slow to catch up with these changes, in both the developing and (in a smaller degree) in the developed world. For the developing world this means a slump in growth until a more educated generation grows up, for the developed world, it means slow job creation. It's not a fault of technology; governments should have seen this coming decades ago. It's a shame that still, in many countries, programming is not required in primary or secondary education.

It's not just about who will build the software, it's about who will use the software.

The way I see it, we're on the edge of going post-material. The trend is that the proportion of the population involved in the manufacture and distribution of physical goods is dropping. Follow that trend for a century, and you get a society where most people's jobs involve only virtual goods (although many of those goods will be turned physical by 3d printers or large bespoke manufacturing companies). Apple and google are the vanguard of the all-digital companies (apple isn't in the business of making stuff, only designing it). This means the majority of people will be making their money producing digital content, and spending it purchasing digital content. Already a sizeable portion of our income is spent on content (tv, dvd, games, books, magazines, ...). I see no reason why that trend shouldn't continue until we have a digital post-material economy.

And if we will have a digital economy, that means most people will be software users, producing content for others to buy. We're not just going to have to train the people that will make the software, but also the people that will use the software. I think the actual production of software will remain a small share of the economy.

I can't wait for the revolution to come to the control and automation industry. I can see the heritage and legacy of the (software) tools I have to use, and unfortunately they aren't so old as to have a unix heritage but to have been born in the windows 95 era.

Probably I just need to pony up and get the real good high end shit, but the automation industry is ripe for disruption like health care too. the problem is the market is small and the stakes are high, so we end with old, expensive, tried, true, ancient solutions.

And herein lies the problem with patent reform.

The patent system is horribly broken, no doubt. But now that everything -- and I mean everything -- is turning into software, what does that mean for patents?

The capitalist answer is that we should let ideas freely grow and fight each other in the marketplace, but having an idea and selling an idea are two completely different skills. We will reward the salespeople, marketers, and business creators at the expense of the ideas people.

Perhaps that is what we want. Perhaps all ideas, not just startup business ideas, will become worthless. Execution will be the only thing that matters. If so, that's going to have some major impacts in the rest of society. It'll be interesting to watch this play out.

While I don't really agree with Marc's take on what's going on with current tech valuations, he hit on one extremely important point, and about it he is spot-on.

There is a major crisis coming in this country if the gap in skills and quality education continues to widen. Too many manufacturing jobs are moving overseas while high-tech jobs are expanding at unforeseen rates. I worry a lot about what's going to happen, and as controversial as it may sound, I think we may see a day in the not-too-distant future where the minimum wage is done away with.

As for Marc's commentary, it seems to me that every significant example he cited was related to content disruption (communications, entertainment, etc.). So I think a more accurate theme would have been "Why Software is Eating the Entertainment Industry."

It sounds like there's two main use-cases here:

- Infinite dragging of a particular element; for example, scrolling in Google Maps or the sort of 'click and drag' UI of a typical billiards or mini-golf game.

- Relative movement events in general, as used for 'mouse-look' in FPS games.

For the first use-case, it should be pretty easy to deal with. Add a property to the 'mousedown' event called 'relativeMode' (or whatever), initially set to false. If the event-handler sets 'relativeMode' to true, then instead of sending the usual string of 'mousemove' events to elements the cursor moves over, the browser should capture ("freeze") the mouse, hide the cursor, and deliver 'mousedelta' events to the original element (whose x and y properties contain the movement delta from the location of the original mousedown event). When the user lets go of the mouse button, the browser releases the capture and shows the cursor. There's no security issue, because the user is in control of the capture at all times, and can just release the mouse button whenever they want.

The second use-case is a bit more troublesome, but as the Chrome bug linked elsewhere in this thread mentions, "web-pages in full-screen mode effectively own the cursor anyway". Perhaps a similar 'relativeMode' property could be added to the 'fullscreen' event.

So you go to a malicious website and it's able to move your mouse around or lock it in place. That would not be a good situation to be in, especially for the segment of the population that doesn't understand keyboard shortcuts (which would, presumably, allow escape from this). Even if it's not used maliciously, it seems very plausible that it would be used to make advertisements harder to avoid (on websites like Hulu that run ads during a video, preventing most users from being able to go elsewhere during them could be a tempting idea).

I get why something with this effect is necessary if we are to have FPS games running in the browser, I just don't think that it's a good idea to allow websites to do so without explicit user permission. Admittedly, there are few things I hate as much as programs moving my mouse around, so I'm a bit biased.

This could be a browser permission based feature, like location is at the moment. The app asks the browser to prompt the user to give permission for this domain to "Control your mouse pointer". The cursor should always be released when you alt-tab away or press the ESC key (maybe the would need to be a time limit within which the mouse couldn't be captured again).

I think a much simpler idea would to have a onmousedelta event which fires whenever the mouse moves and that tab has focus (including outside window boundary) and includes a .deltaX and .deltaY event property.

That way, the user has full control over their mouse and you can also develop fps games.

The proposition that "real names" significantly enhances a user experience is a bit silly, I think. It may contribute in some small way as far as what you're willing to admit, but generally it doesn't seem to change behavior a lot.

The quality of commentary on a public comment platform has much more to do with a given community's moderation and social mechanisms than the username that appears above the comment. YouTube is a mess because it's a hit-and-run system, there is no social obligation, you just type what you think about the video and never look at it again. Additionally, YouTube has a short length limit on comments precluding in-depth discussions, and YouTube's audience is very varied and primarily non-specialized.

There are many public messaging systems online that have flourished and maintain a high level of quality even though they allow pseudonyms. Hacker News, for instance. I can think of five or six high-quality messaging systems wherein I have actively participated off the top of my head that were not flooded with YouTube-esque idiocy -- the name policy really has very little to do with it, I think.

Google+ is completely controlled by its users; you must explicitly accept any author's content that you wish to view and you can block and explicitly reject any author's content that rubs you the wrong way. It is a fundamentally different model than YouTube. In this case, people are generally only going to accept you into their circles if they know who you are at least vaguely, whether the displayed name is "cookiecaper" or "Jeff Cook". I just don't see the point in even having the argument regarding Google+ when it has to be explicitly regulated by the user anyway. Facebook likewise.

I think the real motivation here on the part of both Google and Facebook is to discourage the use of multiple identities so that it's easier to target advertising.

Pseudonymity is still possible, though, so I'm still not sure why this is such a major deal, because you can just go create a Google Account with whatever plausible name you can dream up. You can then reveal your identity to the persons you'd like and everyone else knows you as generic John Smith. In fact, I do this on Facebook, and I presume that many others with an interest in pseudonymity do so as well.

As far as I know faking an ID is a misdemeanor or a felony in most US states [1] and some other countries (like Brazil), so if there is any complaint against a reporter and he is found to have submitted a fake ID he is in for a fine and maybe jail time. I'm personally ok with requiring a user to commit a crime to cause antisocial behavior, as this ensures that they can be prosecuted in some way (this is the same principle behind DMCA takedown notices, where the person sending the letter is liable for a number of crimes if they are not who they claim to be or if they do not in fact own the right to the media at hand).

To solve the perceived "quality" problem (and that perception is itself a problem), Google has, true to form, relied on a technical barrier (must have one and only one first name, one and only one last name). They have then all but automated catching the ones that get through the barrier, by soliciting users to report fakes. Whether they review those reports before notice to suspend is an excellent question, one that Violet Blue has probably asked. https://plus.google.com/105822688186016123722/posts/LWySptwh...

Google's monolithic lack of customer service is well known, and I believe it starts with good intentions, trying to automate the management of the problem as much as possible. The problem comes from believing too much in their algorithms and automated solutions. They're all very smart, but their solutions are not as smart as they think. Or, maybe they're even smarter than I think, and they've gone the Pinto route and calculated that a certain amount of customer "disasters" is relatively tolerable.

Two thoughts on this post/submission. The first is that it's really pretty shoddy, I mean why did it need to be filmed, why not a written (or even to camera) piece that just explains the logic. Anyone who doesn't believe it after having it explained isn't going to believe it after a video of an experiment that could so easily be edited to show 1000 heads out of 1000 flips.

The second is, even if it was presented better, is this suitable for HN? Sure, the topic of probability is suitable, but this is on such a basic level that surely most, if not all, HN readers already comprehended it.

That said, here's hoping that, if people are going to insist on upvoting it, it can at least spur some interesting discussion. With that aim, here's a tangeant:

It's always interesting in gambling how, no matter how mathematically smart someone is, it's incredibly easy to let your heart make decisions for you when money is on the line. Whether it's betting red on roulette because it landed black 6 times in a row, or betting big on a blackjack hand because you've lost your last few in a row and surely it can't keep going.

Even though, as you place the bet, you're thinking "I know the last X spins don't actually have any impact...", you can't help but feel the urge.

I have a theory that I haven't found expounded before. It came from a combination of travel through 60+ countries, living and working and interacting with local people on a pretty intimate level sometimes, and study of lots of history.

It's going to be controversial and maybe even shocking, so brace yourself for a moment before reacting please.

I think peaceful societies self-destruct.

With a few notable exceptions that require a geography suitable to isolationism, long term peace has historically been achieved through your country or one of your ally's having military supremacy over the rest of your neighbors.

Obviously, diplomacy can keep the peace for long periods of time, even human lifetimes, but eventually incidents happen when there's a hothead in one government, and then that's when the military supremacy determines whether you get attacked or not.

Anyways, I've found the more a country renounces war and gets further away from it, the more birth rates go down. You get an explosion of commerce and art for ~30 to ~70 years, and then the society self-destructs.

No longer forced to confront mortality and with no externally unifying cause, people start living for luxury, pleasure, and consumption. They stop having children. Birth rates fall off.

Eventually, this destroys a country's economy, the military supremacy fades, and one of their neighbors comes in and cleans house, and the cycle begins anew.

This has happened many times through history. It's happening in Japan right now. If I became an advisor to anyone in the Japanese government, I'd advocate two things as chief priorities - (1) exceedingly good relations with China, and (2) re-militarize.

Then join the next war they can on America's or China's side. Combined with some standard messages of nationalism/strength/growth/unity, birth rates would almost certainly increase.

I am married to a Japanese and live here right now, so I can only comment on the situation of the country.
I will try to give an economical assessment of the situation. As you might be aware Japan had a “lost decade” during the 90s. It experienced almost no growth of the GDP. There are many theories as to why, but the most convincing one is: The Japanese “Baby Boomers” retired during this decade. In fact the percentage of workers in the population (age 15-64) decreased by 5.6% during this time, as the number of retirees increased by 10.7%. http://goo.gl/kVZxB

What does this have to do with anything? / What happens when you have fewer people in the expected working age?
2 things happen:

  1. More people have to work
2. People have to work longer

The official retirement age for Japanese is 63/61 (M/W), the effective retirement age is 69.5/66.5 http://goo.gl/s9slK very interesting graph)

My wife held a managerial position before our son was born, amongst her friends hardly any of them want to stay single, they simply don't have a choice. If they want to sustain their current life standard, marriage would be impossible. One man working has a hard time providing for his wife, kids, paying for a decent home & the mandatory elderly taxes. The taxes are almost 2000 USD per person / year, no matter if employed, or not. And those are just to pay for the pensions; insurances, social etc. come on top of that.

Many women still life / moved back in with their parents, even in their late 40es. It is not because they want to, or cannot find a partner (many of them look quite stunning). The pensions simply don't suffice and they feel obliged to support their parents. The same holds true for many men.

I very much disagree with the statement that women in Japan enjoy their single life so much, as they choose not to marry. I have yet to meet a Japanese woman, who will state this. Compared to Europe, where this kind of ideology is quite common.

Edit:

Japanese women are expected to do 90% of the housework, where as American women will “only” do 60% of the work. http://goo.gl/qj64W This fact and the very big distance Japanese develop for their spouses are certainly not helping. http://goo.gl/QlAfx Surprisingly no women I ever conversed with, complained about this lack of love between a married couple, on the contrary it is expected by the women. And it often leads to problems in marriages with foreigners.

Edit #2:

If my experience with the Japanese Culture is in any way representative employing more men in the military will be the worst thing imaginable. The country has a deficit of 180% /GDP and every person in the army is one person less doing productive work to keep country afloat.

Edit #3:

When the "Baby Boom" generation will retire in the United states, do you expect the country to sustain a positive GDP? This would mean that every person working will have to work harder and produce more just to reach 0 growth. Something the Japanese managed to do. The only solution to this is immigration, something Japan is battling against.

NY_Entrepreneur 16 hours ago 1 reply      
Seems to me that the article missed the most central point. Let's start with a little, simple, relevant background:

(1) In the past, e.g., in tribal or agricultural communities, women had children whether they really 'wanted' to or not.

(2) Now in more industrialized countries, a significant fraction of women have some options. Some women still have children but some women do not want to have children and do not.

(3) The change in number of children per woman is a 900 pound gorilla in the room: The article mentioned numbers under 2 children per women with a rate a low as 1 child per woman. There is some recent data that Finland is at 1.5 children per woman.

Of course, for any rate much under 2, each 20 years or so the population will be going down significantly. "Get your old houses, furniture, dishes, baby clothes, etc. cheap, cheap, cheap!".

So, net, heavily women who don't want to have children won't. These women will be 'weak, sick, dead limbs on the tree' and will be pruning their genes from the tree. What will be left are women who, given the choice, actually, effectively WANT to have children.

The big point: After a few such generations, we will be left with a much smaller population with many fewer women but nearly all of whom WANT to have children. Then the population will start growing again.

One more big, surprising point: We are now, in much of the world, in the most rapid change in the gene pool of the last 40,000 or so years.

Where did the 40,000 come from? Humans walked out of Africa back there somewhere. At one point, ballpark 40,000 years ago, they reached, say, India. One branch went west to Western Europe, and another branch went east to China and Japan. Mostly the two branches haven't much mixed since then.

Okay, at the common branch, ballpark 40,000 years ago, what were women like? Well, take women from Japan and women from Western Europe. Take some 'characteristic' in common, say, desire of a major fraction of the women, given an economic opportunity, not to have children. Now, start in either Japan or Western Europe and count genetic 'changes' on this 'characteristic' going backwards in the tree to the common branch, about 40,000 years ago, and, then, continuing to count changes, going forward in the other branch of the tree to the present.

So, if on this characteristic the women in Japan and Western Europe are close, that is, have few changes, then on this characteristic the common ancestor 40,000 years ago has still fewer, that is, is closer to the women in both Japan and Western Europe than they are to each other.

Net, since a significant fraction of women in both Japan and Western Europe will, given an economic opportunity, choose not to have children, that is, these women are close to each other, both are still closer to their common ancestor 40,000 years ago. So, for 40,000 years, many women had children not really because they 'wanted' to but because of economic necessity.

So, now that women who don't really want to have children are being pruned from the tree, we are, on this characteristic, in the most rapid change in the human gene pool of the past 40,000 years. And, the change is VERY rapid, should have a huge effect in just a few generations, say, just 100 years, which on the scale of 40,000 years, is FAST.

Good for them. More people need to reject this archaic sexist tradition. Legal enforcement of the fantasy notion of "true love for life" is damn near barbaric.

If you and your partner can swing it, more power to you, but social pressure on others to place themselves into legally binding situations revolving around this notion is something that need to die.

In the west (at least the states) these are legally binding arrangements that are heavily biased against males, but if women are rejecting that in Asia then all the better.

Is it really the women who are avoiding marriage?

Do this experiment: go to a newspaper stand and look for magazines about weddings. Look for books about marriage. I have never ever seen one addressed to men (there are ones which seem to be, but on a quick glance I actually think they were written to feed the women's ego), which means IMHO that men wouldn't spend money on subjects like these. Meanwhile you sholdn't be surprised to find at least half a dozen for women. So I really really doubt that men are more willing to marry EITHER.

I would actually dare to say that men were (and still are) the ones who don't really care about marriage.

I don't get what his results have to do with the Fibonacci sequence. Between his "control" and the design he was testing, he changed:

1. panel heights
2. panel angles
3. whether panels were stacked or not

I would guess that any of those three things matter way more than the position of the "leaves" following the Fibonacci sequence. He needed to compare his design to a similar tree-shape whose "leaves" were, say, uniformly or randomly spaced; not to what amounted to a patch of moss.

(Which brings to mind: solar panels which were shaped more like moss (i.e. rough) would probably perform even better. I'm pretty sure I remember MIT or some place building a prototype like that.)

Finally, he measured voltage but made claims about power, which is a huge no-no for solar PV. Solar PV panels have highly nonlinear voltage/current characteristics, which means that increased voltage does not correspond to increased power, especially in setups such as the tree where the solar panels are not uniformly illuminated.

1. Like others said this is in comparison to a flat non tracking solar panel, the tree configuration would lose out significantly against a tracking panel.

2. Fairly disingenuous graph on the second page, but then again professionals in business and science do this all the time as well.

3. With the current state of solar technology this patent is useless. But if someone invents solar cells who are so cheap that they cost less than the solar tracking equipment, this could become quite a lucrative patent.

4. I wasn't aware you could patent things which are this directly copied from nature. I was under the impression that you could say patent a mechanism which emulates the motion of a specific fish but not the motion itself, or can you ?

It seems like trees are trying to maximize the density of leaves they can accommodate, balancing that against the decreasing usefulness of each leaf. I suspect using the tree placement you could produce much more energy per square meter of land, because you could fit so many more panels.

Imagine if a tree's leaves were arranged in a grid. The footer would be enormous. If you are making a solar farm. In the desert with sun-tracking panels, I don't know how much this improves things, because there isn't much limit on land. But in a city, on rooftops, in backyards, etc, you might be able to get a lot more total energy out of a given plot this way.

I find it amazing that with all the interest in bio-mimicry, this hasn't been tried before. Did nobody ever ask why all plants share a very similar architecture?

They've even made solar cells that look like leaves before http://techon.nikkeibp.co.jp/english/NEWS_EN/20080527/152443..., but nobody bothered to test if a tree-like structure gathered more energy.

i think this is great. not that he was 13 (though it is impressive), but that he thought enough to challange the typical panel array that we've gotten solar power from in the past. it seems that he got some interesting results, too. sure, maybe he didn't take some things into account, or maybe it's not super practical, but breaking out of the mold of large, 2d rectangular panels may be something the solar energy world needs to innovate on ways to harness more energy from the sun efficiently.

The panels on the tree are higher than those on the flat plane - you'd expect to get more light for longer from that alone.

Why there aren't many innovators in China joezhou.posterous.com

China has long culture of believing in studying hard and becoming part of the system as the route to success. (The imperial exam system.) Although it no longer formerly exists, there are analogues and the influence is still there. It is ingrained from birth that you study hard, get into the right university then reap the rewards. Beijing locals I talked to were puzzled by the idea that government workers in the west could get in trouble by accepting gifts and favours. In China, that's the main reason you would follow that career path.

This doesn't lead to a very entrepreneurial culture, although there are many who will still try to start their own business. Then you start to hit the barriers discussed in the article. Another barrier you can hit is that if you start to become successful, the government will appoint a party member to your management. Further, if you are in certain fields, the government erects tax and regulatory obstacles that will create an advantage for state-owned enterprises.

It's unfortunate... there are enough in the under-35 age group, who might actually break out of the old culture and innovate. They face a lot of obstacles and that will be bad for China's long-term outlook.

I'm a Chinese Malaysian and pretty familiar with Chinese culture and their ways. For those of you who might be skeptical, I think this article quite accurate.

I've tried hard to think of recent Chinese tech inventions that are truly new, and not a ripoff of a popular existing product, and could never come up with any, until just recently. I bought one of these "Air Fly Mouse" http://www.airflymouse.com/ and it works as advertised! Here's to more innovation coming from China.

Where's the incentive to innovate if you have a huge market with tremendous cultural barriers to entry for the most innovative companies in the rest of the world?

Sorry, can't read the article, blocked here(China). There is plenty of money here, especially if you've got a good idea and whats needed, no shortage.

But China in general doesn't do different or new or innovative. They do better at the same thing, where better usually means cheaper, but not always. If they can't compete in that way, then they just try to get the government to crush any non-Chinese competition.

That's why I was pitching so many times to my friends. Why not go to Taiwan first? Small island for testing the foreseeable mainland market, initial understanding the culture and language, and enjoy freedom of speech and better human right. Mostly OEM industry HQ are all right here. All you have to worried are air pollution, the crazy traffic, and the heat, humidity tropical weather. There is a site called techorange dot com blog talked about China and Taiwan startup. You can have a look.

This was the most damning line in the article and points to a genuine breakdown in the ecosystem, or lack thereof:

"Actually a more common practice is that VCs would have take one of the pitches he really likes and just hire a bunch of engineers."

In America intelligence is seen as Yankee ingenuity, building a better mousetrap. Talking back to your superiors and finding a better way is smiled on if you can produce results in the states.

In china, intelligence is seen as efficiency, doing something well, getting the right boxes filled on the exam, non-intelligence related things that are called intelligence. Go talking about how the yuan is pegged to the dollar instead of gold and the government won't hire you because you aren't parroting the group think (I have experience talking to some china-women about this). Try to break out of your class and get beaten back into it.

It's the culture. I really think if china could break out of it's meek-slave mentality and have them start thinking that the Earth is theirs for the taking if they want it, then it could blow United States out of the water a thousand times over. Educate the meek slave class sleeping giant with care! It took thousands of years to craft a group of people who will work and not fight back when exploited.

The internet in China isn't that good. Transfer fees are slow, there is a lot of government censorship, and not many people can afford it. Why invest in a risky internet startup, then, when there is much more money to be made in manufacturing or real estate? So the financial incentive to invest in a tech startup just isn't there. It's probably also difficult for potential startups to get good engineers, as the brightest students usually go into government or work for one of the large government-sponsored corporations that dominate the economy.

The reason I think - China is choked for capital. Yes, there is money, but not a lot. Unless you are doing are doing a government contract (i.e. building infrastructure) or are in real estate, you don't get much capital. Interest rates are artificially low, but only if you can get a loan - i.e. you look very very safe. Why bother investing in business, when you can borrow at a low rate and invest it in houses?

Chinese businessmen look rich. Some of them do have a lot of money, but most are just richer than the average Chinese worker. And because the poor Chinese workers are poor, they can't bootstrap their way up so easily.

My read on China is that there is a weaker society culture while also having a stronger family culture. This probably means that a lot of startup financing will be from families as the middle class grows and there is spare cash around.

Well, that's bound to happen when a generation suddenly becomes rich for first time in long family history. You kind of had it coming.

It'd take some metabolism cycles to ingest the wealth they come by. Until then they'll act like pigs on money steroid rather than the rich.

Best to avoid the shitbag of shitstorm until they learn to be civil.

Kernel the language can be found here: http://web.cs.wpi.edu/~jshutt/kernel.html

Where the author mentions that it is related to his doctoral dissertation, Fexprs as the basis of Lisp function application; or, $vau: the ultimate abstraction[1].
