"A China that leads the world will not offer the chance to be Chinese, because it is impossible to become Chinese. "

Of course. The British led the world and did not offer (at the time) anyone the chance to be British either. In fact, they actively discouraged interbreeding. It is a dogma of the modern Occident that it is stronger to be multi-ethnic, and that national identity should be open to anyone. History shows us, however, that that is hardly a necessity for world empire.

Full disclosure: I was once in love with a Chinese woman from an elite family, who I am fairly certain loved me but rejected me because I did not belong to the appropriate stock (with influence from her family). Lesson learned: if love is strong, kinship bonds are often stronger.
When you go to the their home page, it looks like a monthly service. Building from source looks somewhat cumbersome: http://wiki.alfresco.com/wiki/Alfresco_SVN_Development_Envir...

They appear to have a freemium pricing model. http://www.alfresco.com/products/compare

Alfresco looks like a great product. I'm picturing a set of unix-like tool built of small components that each do one thing well. Perhaps a set of rails plugins, which probably already exist. Alfresco seems a bit monolithic. Perhaps this is just a fact of life with any CMS/Collaboration software. Alfresco has add-ons, too. I'm sure it's head and shoulders above Sharepoint in terms of deployment and usability.

edit: I think Asana looks great: http://asana.com/
Mind-bending.
I love it: these unpaid, enthusiastic volunteers are providing real, honest customer service -- as opposed to the theater of customer service one normally gets from the paid "customer support" staff of large organizations.
The volunteers were great, but not perfect. They needed to be more selective about which roles the volunteers were capable of handling. This story comes to mind: http://1045theteam.com/american-tv-neglected-the-saddest-sto...

Sounds like "your biggest problem without vim."

Like many others, I've been happy using Sublime, recently. But not quite completely satisfied (For instance, I couldn't figure out a working regular expression to remove all extra whitespace from the end of a line, in sublime, so I did that task in vim where it works.)
Also if one machine is not updated (due to no network, for example), the file still exists there.
"Deal Score is a rating of whether a ticket is a bargain or a rip-off".

Are there any linear algebra books which use machine learning as the motivating example? Or a book which teaches linear algebra and machine learning together?
The reasoning is flawless.

You need to spend less effort to train your employees because they enjoyed a certain level of schooling (which, chances are, you enjoyed too). If you don't need to build your own roads it's because everyone paid for a shared road system. You don't need to enforce laws yourself because your taxes support law enforcement. Of course, people who pay less taxes have (or should have) the same enforcement as you do but that's because of one other thing - that the law applies equally (or, again, should apply equally) to everyone. As it should, John Galt or not.

"John Galt" is about self-entitlement. Is about ideas without regard who actually executes them.

This community, I thought, understands the fact that ideas, without execution, are worthless. And execution, without employees out of a vastly interdependent society, is a whole lot harder.
It's a long shot, but worth a try:

What is even more amazing is that this mimics nature. Most trees have a root structure that is a rough mirror image of what's above ground!
True. But this is all a rabbit hole. I think the upper comment was trying to point out that real linear algebra already has work from a trial vector methods of solution. So there is some precedent for non-factorization based solutions. But even that detracts that this really does seem to be a new method for finite fields.
This book spends three chapters on the mechanics of matrix operations before defining a vector space, and then it jumps into determinants.

IMO this is the wrong way to understand linear algebra, and the typical path of a lot of introductory text books. A better text: Axler's "Linear Algebra Done Right"
This is a strange article. It seems a bit gloaty to champion the myriad volunteers working at a for-profit event, but this story isn't about the volunteers. It's about how the organization benefits from them, as a "lesson to business." Well no kidding they benefit!

The R&D scientist, the shop-keeper and their "honest advice," the bartender who knows your name, and other examples of simply giving a crap, are used in service of "engagement," and "alternative customer experience[s]." There is not one iota of critique for how companies breed enthusiasm out of the people they pay, much less those who are volunteering, and least of all how crappy companies are made, but that's obviously not what they were trying to do...but what is the point of this story? Even people given to slavery without smiles aren't going to get anything out of this article.

Coming from the HBR, an site notable in irony for running this story at the same time the top-selling item in their store is a 7-page case study entitled, "PCL: A Breakdown in the Enforcement of Management Control." Maybe PCL just needed more happy volunteers? One thing is for sure: when half of your workforce is unpaid, it's not hard to make your numbers.
Vimperator/Pentadactyl's numbered links are doing the same thing for me. Hit the "f" key and anything "clickable" on the screen is overlaid with a number. Type the number and enter and you've "clicked" it. It's ingenious.

I dream of an entire OS supporting this.

Regarding Vim fluency spoiling IDEs, I could not bear writing C# code in VS without purchasing the $99 ViEmu ...and that's coming from someone that drives a 1987 F-150.
I don't have this problem, just like I don't have a problem with typing both English and Russian on a single keyboard: my brain have learned to switch contexts. I don't use vim-like plugins for anything. :wq
Sadly you need a hefty amount of it to get to machine learning that uses linear algebra in a nontrivial way.
Tunnelling under cities has a number of odd problems.

(http://www.telegraph.co.uk/news/1527202/How-top-secret-tunne...)

I read an article, some years ago, about the problems of getting subterranean tunnels at a depth greater than 100 foot approved. As part of the process the plans get submitted to the security services, who then say "yes" or "no"; and you only get three attempts. I can't find the article (or anything similar) so maybe it's just myth.

The Moscow subways are beautiful, but when I went (April '86) you were not allowed to take any photographs.

I'm fascinated by the complex networks of public tunnels, secret tunnels, and abandoned tunnels.

You're the one who's doing the hating my friend... you keep finding hidden messages in what I write and generally piling up on PHP without good reason. I never said anything bad about Go, or bad library support in other languages, just not agreeing with the article on comparing PHP to it where PHP is (in my humble opinion) a very strong option already.
These business models sound reasonable, as long as the supporting materials are truly supplemental. An open textbook that is complete (for example, with problems and exercises), is a good thing. If the text becomes an advertisement for the supplemental materials, then we have missed the mark.
So, there are two of those deep underground water tunnels, one which runs down from the Bronx through Manhattan and another that runs from the Bronx through Queens and Brooklyn. These tunnels were completed in 1917 and 1935 respectively. How they managed to do this then is beyond me.

Currently a third tunnel is being built and apparently it's "the largest construction project in New York history". The project was begun in 1970 and won't finish until 2020. It cost 6 billion. When the third tunnel comes online, it will allow for the other two tunnels to be shut down for repairs for the first time in their history. Scenes from Die Hard were filmed in Tunnel 3.

This is big, long-term stuff folks. Makes me feel kind of proud of civilization.

This stuff has just been in the air the past few years - Network coding ( http://www.eecs.harvard.edu/~michaelm/CS222/contentdist.pdf ) does the inverse operation to increase efficiency in Bittorrent-like distribution schemes. It is quite cool that randomness can help in both the creation and solving of these problems.

I think you're reading into it too much, and you're taking it too far away from the context between Dad and Daughter. This is, and will be, their own personal experiences. For some starting a hedge fund can be seen as high-risk, when for someone that has run one for years (Dad's case) or for someone that's been around one for years (Daughter's case) it can be seen as low-risk.

If Dad was an MD he would've said don't become a surgeon, do research and try to change current procedures. At least that's my take on the blog.
I think we've all had our John Galt moments. A righteous indignation at rentiers, large and small. It comes from a good place--the sense that you are giving something to others.

But there is a lot of give and take in the world, some easily observed and measured, some not. Some attributable, some not, and in proportions that vary over time.

Frankly, I don't know how much I take. Some dimensions are visible and quantified, but not all. So when I do give, I am happy--happy to be filling the well of life.

I code mostly in Ruby(professionally) and had pull requests accepted in rails/rails and another open source project, but I live in a third world country with no direct immigration benefits to live in another country.

Also, does any of you have any experience in actually preparing physically, emotionally and professionally, to move to a better country and got any tips?

Attack of the Acqui-hires
Please be more specific. I can think of an example off of the top of my head using the Interstate Highway System to support my argument.

The end points of I-80 are New York City and San Francisco. Both cities predate the Interstate system by a good margin. Both started off as Trading Posts that gradually became more successful (http://en.wikipedia.org/wiki/New_York_City#Early_History, http://en.wikipedia.org/wiki/Mission_San_Francisco_de_As%C3%...). I-80 connects the two cities because that is where the people were. The people were there because of successful entrepreneurship. Furthermore, through tolls and fuel taxes, the people in those areas continue to subsidize the maintenance of the nearby sections of I-80.

Tumblr and Twitter use Scala to solve their nice-to-have scalability problems using a services-based architecture. This is "core functionality must protected at all costs" conservatism.

It's not just you! http://browserver.org looks down from here.
I don't think so. You'll notice that at the 1:30 mark he's switched from using the remote to the mouse. The pointer/cursor interface, even 20 years later, just doesn't work well when you're aiming at a screen occupying a (relatively) smallish span of your field of vision from 8-20 feet away, potentially at an angle.

My guess is that speech removes the need for typing, and everything else is via a one button remote with a whole host of gesture "smarts". Imagine flicking your wrist up to scroll and you'll have the idea.
And they're down.

It was a good 15 minutes, though.
Slightly related: There were a couple days way back that I really wanted to learn to type on a dvorak keyboard (later lost interest). One of my friends was doing the same (he also later lost interest) and gave me the tip that I should figure out which thumb I generally press spacebar with when typing on a qwerty board (my right thumb) and use my opposite thumb when typing dvorak. I found this worked really well, I was able to seemlessly switch between my mostly-incompetent dvorak typing and my good qwerty typing without any mental effort.
Anyone have any recommendations for linear algebra courses through Coursera or similar sites? It is a subject I've always been fascinated by but my self-directed learning endeavours have not yielded much usable knowledge.
By "primitive data types" I didn't mean to exclude built-in collections of primitive data types. Point taken, though: I probably should have said "built-in data types", or some such. I didn't even mean to exclude algebraic data types, as I explicitly mentioned.

Though I think that the question of whether algebraic datatypes should be allowed is an interesting one. Also, clearly allowed would be any objects provided by the standard library, since returning those would not couple your code to the code of the API.

As Rich Hickey expresses it, I believe, you should only return from an API data that you could send over the wire without sharing any of the API's code. If you stick to this rule, then, for instance, it is much easier to make your application distributed.

(Though I'm not sure to what degree Hickey and The Law of Demeter would agree on everything. E.g., returning some hairy nested dictionary of dictionaries of dictionaries of strings to represent a book, or what have you. I don't know what Rich Hickey would say about that.)
"the few of us"? Over 2/3rds of all working age Americans have a job. The majority of those who don't are raising kids. The majority of the remainder want a job but can't get one. There are a few mooches, but the few thousand they get every year in food stamps is a drop in the bucket compared what is stolen from the economy each year by those doing "unproductive work" -- ie work that benefits themselves but does not benefit or actively harms society. HFT, patent trolling, bribing politicians, et cetera.

"How did the LIBOR scandal cause millions or billions to suffer? As I understand it, a big part of the scandal is the rate being set lower than it should have been..."

Ok, let's assume they were set lower for argument's sake. Then cities, mutual funds, and pension plans would have earned less than they would have had the rate not been manipulated. Let's examine cities from that list - as you look around the the world today, there's not a lot of cities that seem flush with a surplus of cash. They've got a decreasing tax base as a result of a precarious economy and now they've got decreased investment returns as a result of LIBOR being manipulated down. As a result, they either cut services or raise taxes - both of which have a negative impact on the millions and billions living there.

I accept your premise but reject your conclusion. Rather than claiming that the problem is an interdependent society and the solution is every man/woman for him/herself consider the following quote by Thomas Paine (a liberty-minded founding father of the United States)

"Personal property is the effect of society; and it is as impossible for an individual to acquire personal property without the aid of society, as it is for him to make land originally.

Separate an individual from society, and give him an island or a continent to possess, and he cannot acquire personal property. He cannot be rich. So inseparably are the means connected with the end, in all cases, that where the former do not exist the latter cannot be obtained. All accumulation, therefore, of personal property, beyond what a man's own hands produce, is derived to him by living in society; and he owes on every principle of justice, of gratitude, and of civilization, a part of that accumulation back again to society from whence the whole came."

I used to be a fierce Libertarian and then I realized that Ayn Rand's Objectivist utopia ALREADY exists in Somalia and Sudan and many other nations in the world - none of which I would call civilized.

Now if you were to call out the massive corruption in the current system as the root cause, I would jump to your defense.
Numpy/Scipy are used for serious applications (I use them myself), but I think that the domains are different enough that the comparison is slightly unfair. Comparing Numpy to R for statistical analysis is like comparing R to Rails for web development.

Numpy isn't a statistics package. It's a linear algebra package. It's less of a poor-man's R and more of an easy-to-read APL.

As for the complexity and documentation, I honestly don't know where he's coming from in that regard. I've taught numpy to a variety of scientists in the department and they've always found it quite simple. The documentation is also thorough enough that these same people can use it to answer their own questions.

I'm just a non-computer scientist who mainly codes in Python and Matlab, but a lot of these suggestions (making a number a vairable if it is used more than once, etc) seem like normal coding practices to me. Do very many coding tutorials leave out this sort of thing?
I'd be willing to bet money that after you add up the salary, bonuses, and benefits, the amount of money Google spends on the average Googler isn't all that much different from the average investment banker.
Liquidity is just cash representation of existing wealth.

HFT doesn't create any value. You take already created wealth and based on demand supply equations some one looses and some one gains. Think of it like a kilogram of potatoes changing 100 hands in a day during some make money and some lose depending on how the demand for potatoes is in a city. The HF traders don't actually do anything to grow potatoes or help the process of growing potatoes.
So, in light of this news, where does FDIC come in? In a calm, yet serious sense, the reason people in the US trust our banks is because our money is insured by the US government. Does what has been said here have any effect on that? --- or, does it at least have the potential for affecting that?

Hey all,

I put browserver together in my free time over the last week. It's still a bit of a toy, but I think it's useful to explore ideas around extending webhooks all the way to the browser, to simplify our increasingly complicated web architectures.

It's already late here in Tokyo, but I'll be up for a bit if anyone wants to chat/brainstorm about approaches like this (and also to make sure the server stays up).
