"Google seems to think it's above America's laws."

... No, it seems to think that particular law is unjust, and as responsible citizens, they are duty-bound to fight it.

Perhaps in meeting point 4, we should skip your summary?

Preface: Something I've noticed about jerks/assholes: they're convinced that they're surrounded by jerks and/or assholes. Almost none of them are jerks for no reason. They're almost always jerks in response to some slight (either imagined, or blown way out of proportion). A good sign that you might be a jerk is that you see jerks all around you. Most people are basically all right. If you (1) run into conflicts with a lot of people, please consider the possibility that you are at least part of the cause.

Actual Point: The reason I am hesitant about following the advice of this article is that it encourages you to divide the world into jerks and nice people. It's very easy to be a jerk to a jerk. If you are a jerk to a jerk, suddenly everyone on the project has to deal with two jerks.

I do agree that there are behaviors that just shouldn't be accepted, and there are lots of examples of them online. But you (2) do need to be mindful of your response to those behaviors. Make sure your response isn't to engage in those behaviors yourself.

(1 & 2) and by you, I mostly mean me. I am totally writing to myself here.

I can't believe this simple, kind of stupid thing I did has gotten so much attention. I also can't believe so many people hate Stella. It's not the greatest beer I've ever had, but it's no bud light.

LinkedIn made $15 million dollars last year, and they just raised $660 million dollars out of the gate in this IPO. And, this IPO values LinkedIn at somewhere close to 6.5 billion dollars.

A valuation of 6.5 billion dollars on $15 million net income. Let that sink in.


The author raises a number of interesting questions after citing several path-breaking research studies. Why, indeed, aren't school systems adopting some of these techniques known to improve children's learning and problem-solving ability? Quite a few mathematicians have written critiques of United States practice in teaching primary and secondary school mathematics, informed by practice in other countries, for example Hung-hsi Wu,

All those mathematicians think that the United States could do much better than it does in teaching elementary mathematics in the public school system. I think so too after living in Taiwan twice in my adult life (January 1982 through February 1985, and December 1998 through July 2001). Taiwan is not the only place where elementary mathematics instruction is better than it is in the United States. Chapter 1: "International Student Achievement in Mathematics" from the TIMSS 2007 study of mathematics achievement in many different countries includes, in Exhibit 1.1 (pages 34 and 35)

http://pirls.bc.edu/timss2007/PDF/T07_M_IR_Chapter1.pdf

a chart of mathematics achievement levels in various countries. Although the United States is above the international average score among the countries surveyed, as we would expect from the level of economic development in the United States, the United States is well below the top country listed, which is Singapore. An average United States student is at the bottom quartile level for Singapore, or from another point of view, a top quartile student in the United States is only at the level of an average student in Singapore. I've been curious about mathematics education in Singapore ever since I heard of these results from an earlier TIMSS sample in the 1990s.

The article "The Singaporean Mathematics Curriculum: Connections to TIMSS"

http://www.merga.net.au/documents/RP182006.pdf

by a Singaporean author explains some of the background to the Singapore math materials and how they approach topics that are foundational for later mathematics study. I am amazed that persons from Singapore in my generation (born in the late 1950s) grew up in a country that was extremely poor (it's hard to remember that about Singapore, but until the 1970s Singapore was definitely part of the Third World) and were educated in a foreign language (the language of schooling in Singapore has long been English, but the home languages of most Singaporeans are south Chinese languages like my wife's native Hokkien or Malay or Indian languages like Tamil) and yet received very thorough instruction in mathematics. I hope that all of us here in the United States can do at least that well in the current generation.

P.S. Another reply mentions the Flynn effect (secular increase in raw scores on IQ tests from generation to generation in most countries worldwide), and links to the Wikipedia article. Thanks for bringing that up. Being aware that the Wikipedia article on that subject has been subject to edit wars that have gone to the Wikipedia Arbitration Committee,

http://en.wikipedia.org/wiki/Wikipedia:Arbitration/Requests/...

I think it may be helpful to link to another source about the Flynn effect

http://cscs.umich.edu/~crshalizi/reviews/flynn-beyond/

that has had the influence of better informed and more impartial editors. There are several good discussions of the Flynn effect in recent books on IQ testing, and citations to those can be found in Wikipedia user space.

If obscurity is useless, then why does the Army camouflage tanks? Why not just paint them blazing orange/pink and let them stand on their own defenses? There is a place for obscurity in security and the endless parroting of "security through obscurity is useless" should stop.
