Google vs. memory...
Unfortunately, that is the curse of all technology -
First we do not bother to remember small things.
Since we cannot recall small things quickly, we lose our edge.
Then we lose our ability altogether in that domain.
Google is to human memory what the calculator was to arithmetic ability -- replacement.
Losing "Being Lost"
Right now, Nokia is designing global positioning system receivers into every new mobile phone they plan to sell. GPS receivers in a phone SIM card have been demonstrated. GPS is exploding everywhere. It used to be for navigating battleships; now it's in your pocket, along with a moving map. And GPS is pretty crude — you need open line of sight on the satellites, and the signal's messed up. We can do better than this, and we will. In five years, we'll all have phones that connect physical locations again, instead of (or as well as) people. And we'll be raising a generation of kids who don't know what it is to be lost, to not know where you are and how to get to some desired destination from wherever that is.Predicting the future is tough business, and anyone might get lost in the eddies of time, but not in 3D space anymore, it would seem. Another one: driverless cars."Being lost" has been part of the human experience ever since our hominid ancestors were knuckle-walking around the plains of Africa. And we're going to lose it — at least, we're going to make it as unusual an experience as finding yourself out in public without your underpants.
They're going to redefine our whole concept of personal autonomy. Once autonomous vehicle technology becomes sufficiently reliable, it's fairly likely that human drivers will be forbidden, except under very limited conditions. After all, human drivers are the cause of about 90% of traffic accidents: recent research shows that in about 80% of vehicle collisions the driver was distracted in the 3 seconds leading up to the incident. There's an inescapable logic to taking the most common point of failure out of the control loop — my freedom to drive should not come at the risk of life and limb to other road users, after all. But because cars have until now been marketed to us by appealing to our personal autonomy, there are going to be big social changes when we switch over to driverless vehicles.One thing is fairly clear - dreamers will never be out of business!Once all on-road cars are driverless, the current restrictions on driving age and status of intoxication will cease to make sense. Why require a human driver to take an eight year old to school, when the eight year old can travel by themselves? Why not let drunks go home, if they're not controlling the vehicle? So the rules over who can direct a car will change. And shortly thereafter, the whole point of owning your own car — that you can drive it yourself, wherever you want — is going to be subtly undermined by the redefinition of car from an expression of independence to a glorified taxi.

France+ US = Canada ?
France is very socialist and the US is very capitalist; time-wise, the French value leisure, the US, work; the French emphasize equal society, the US, meritocracy; the French take care of their poor but shun the immigrant (an immigrant is a foreigner even if legal and 3rd generation, there is no way to ‘become French’), the US welcomes immigrants (comparative to almost any western nation) who want to work and embrace our values but we don’t take care of our poor. We both, however, tend to be nationalistic, arrogant, deeply politically divided, and idealists about our countries’ history and founding values of freedom and equality.As France has moved left, the US has moved right, and it seems that both countries are having a little buyer’s remorse. Wanted: A country with lofty goals, a society that recognizes that hard work is the force that creates a civilized world, but also that it isn’t worth much if you don’t take the time to enjoy and think about the civilization you’re working so hard to create, one that wanted to include all members of it’s society no matter race or social class, but also kept a strong sense of identity and individual freedom. Let’s see, a cross between the US and France. Hmmm…Canada, anyone? Yeah, really friendly people would be a plus, too.

false positive vs. false negative
To Google, hiring is mathematically equivalent to Information Retrieval, except that they only care about "precision" not "recall".Also, read Two Kinds of Judgement, which discusses this issue in some depth.
What that means to lay-people is that so long as they can maintain 10,000 applications coming through per-month, false negatives (passing on a suitable applicant) do not matter because there'll be another candidate along in a minute. False positives (hiring an unsuitable applicant) are all they need to focus on. The "fit factor" is effectively the search string of traits; however, with such a large candidate pool, they can focus their "hiring algorithm" entirely on rejecting candidates where it is even slightly difficult to ascertain whether they fit or not.
So, their advertising blitz "aren't we a great place to work for" is a part of what lets them keep their hiring process easy. If they get bad PR and applications fall, then they'll need to worry about recall as well as precision.

Cubicles, not walls in offices..
We're going to need a much bigger space now: on the order of 15,000 square feet. To build that much office space could cost a couple of million dollars. With the lack of deductibility, your bank account goes down by three million dollars. The landlord will pay a fraction of that, but not enough to make it affordable.
There's a loophole. Office furniture can be depreciated much faster than leasehold improvements, over 7 years. So for $20 of office furniture you can deduct about $3 a year: better than nothing. Even better, office furniture is a real asset, so you can lease it. Now you're not out any cash, just a convenient monthly payment, which is 100% deductible.
This is why companies build cubicle farms instead of walls, even though the dollar cost is comparable.

Not all beauty is in the eye of the beholder!
My main point here is not how to have good taste, but that there can even be such a thing. And I think I've shown that. There is such a thing as good art. It's art that interests its human audience, and since humans have a lot in common, what interests them is not random. Since there's such a thing as good art, there's also such a thing as good taste, which is the ability to recognize it.
Art is man-made. It comes with a lot of cultural baggage, and in addition the people who make it often try to trick us. Most people's judgement of art is dominated by these extraneous factors. ... So it turns out you can pick out some people and say that they have better taste than others: they're the ones who actually taste art like apples.
... the people [with good taste are the ones] who (a) are hard to trick, and (b) don't just like whatever they grew up with. If you could find people who'd eliminated all such influences on their judgement, you'd probably still see variation in what they liked. But because humans have so much in common, you'd also find they agreed on a lot. They'd nearly all prefer the ceiling of the Sistine Chapel to a blank canvas.

Software Development at Microsoft.
... that nets us an estimate ... of 24 people involved in this feature. Also each [of the three teams] was separated by 6 layers of management from the leads, so let's add them in too, giving us 24 + (6 * 3) + 1 (the shared manager) 43 total people with a voice in this feature. Twenty-four of them were connected sorta closely to the code, and of those twenty four there were exactly zero with final say in how the feature worked. Somewhere in those other 19 was somebody who did have final say but who that was I have no idea
[H]ere's how the design process worked: approximately every 4 weeks, at our weekly meeting, our PM would say, "the shell team disagrees with how this looks/feels/works" and/or "the kernel team has decided to include/not include some functionality which lets us/prevents us from doing this particular thing". And then in our weekly meeting we'd spent approximately 90 minutes discussing how our feature -- er, menu -- should look based on this "new" information. Then at our next weekly meeting we'd spend another 90 minutes arguing about the design, then at the next weekly meeting we'd do the same, and at the next weekly meeting we'd agree on something... just in time to get some other missing piece of information from the shell or kernel team, and start the whole process again.
Windows has a tree of repositories: developers check in to the nodes, and periodically the changes in the nodes are integrated up one level in the hierarchy. At a different periodicity, changes are integrated down the tree from the root to the nodes. In Windows, the node I was working on was 4 levels removed from the root. The periodicity of integration decayed exponentially and unpredictably as you approached the root so it ended up that it took between 1 and 3 months for my code to get to the root node, and some multiple of that for it to reach the other nodes.
So in addition to the above problems with decision-making, each team had no idea what the other team was actually doing until it had been done for weeks. The end result of all this is what finally shipped: the lowest common denominator, the simplest and least controversial option.

More interested in feeling good than doing good.
... the way we choose to dole out cash betrays our true motives. Someone with ₤50 to give away and a world full of worthy causes should choose the worthiest and write the cheque. We don’t. Instead, we give ₤2 to the street collector for Save the Children, pledge ₤15 to Comic Relief, another ₤15 to Aids research, and so on. But ₤15 is not going to find a cure for Aids. Either it is the best cause and deserves the entire ₤50, or it is not and some other cause does. The scattergun approach simply proves that we’re more interested in feeling good than doing good.
None of this is to say that these contributions are worthless nor economically insignificant. Just don’t get too starry-eyed about the motives behind them.
Made in Japan
... during the Vietnam war ... as early as 1965 the military build-up was being hampered by what the journalist Marc Levinson calls “the greatest logistical mess in the history of the US armed forces”. In The Box, Levinson’s new book about the shipping container, he argues that container shipping provided the answer. Once the military was sold on the idea, there were two swift consequences: a dramatic expansion of container shipping to US forces in Europe, and fleets of empty ships sailing back from Vietnam, offering cheap rates to the rapidly expanding Japanese manufacturers. The rest is history.

Too busy to...
Personal value systems ... can guide a person's decisions as much as monetary measures can. A simple stir-fry dinner ... comes in one of two ways: ready-made or made from scratch. Though the ready-made meal might cost more, someone who earns $30 an hour might not mind coughing up an extra $5 (about ten minutes' worth of wages) to save ten minutes of preparation time in the kitchen. That person might value convenience more than culinary prowess.Everything is just another chore to be finished ASAP. No one has time to stop, stand and stare.

How to start a war?
“Why, of course, the ‘people’ don't want war. Why would some poor slob on a farm want to risk his life in a war when the best that he can get out of it is to come back to his farm in one piece. Naturally, the common people don't want war; neither in Russia nor in England nor in America, nor for that matter in Germany. That is understood. But, after all, it is the leaders of the country who determine the policy and it is always a simple matter to drag the people along, whether it is a democracy or a fascist dictatorship or a Parliament or a Communist dictatorship…. The people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are being attacked and denounce the pacifists for lack of patriotism and exposing the country to danger. It works the same way in any country.”Three Interesting methods to start a war (scroll down to Feb 13, 2007):
(1) The FDR way of manipulation (Japan)
(2) The LBJ way of forgery (Vietnam)
(3) The GWB way of invasion (Iraq)

Inequity in wealth distribution
In their study for the World Institute for Development Economics Research, Giovanni Andrea Cornia and Julius Court (2001) reach policy conclusions as to the optimal distribution of wealth. The authors recommend to pursue moderation also as to the distribution of wealth and particularly to avoid the extremes. Both very high egalitarianism and very high inequality cause slow growth. Extreme egalitarianism leads to incentive-traps, free-riding, high operation costs and corruption in the redistribution system, all reducing a country's growth potential.
However, extreme inequality also diminishes growth potential by eroding social cohesion, and increasing social unrest and social conflict, causing uncertainty of property rights. Therefore, public policy should target an 'efficient inequality range'. The authors claim that such efficiency range lies between the values of the Gini coefficients of 0.25 (the inequality value of a typical Northern European country) and 0.40 (slightly lower than that of countries such as China and the USA). The precise shape of the inequality-growth relationship depicted in the Chart obviously varies across countries depending upon their resource endowment, history, remaining levels of absolute poverty and available stock of social programs, as well as on the distribution of physical and human capital.

Internet and adult entertainment.
Clearly one of the main reasons initially for getting on the Internet was sex. If you look at the words almost any one of the Internet suppliers has kept track of, you'll find that "sex" is probably the most frequent word used as they look for programming of any sort. So clearly, there is a desire to see it.
I think what Yahoo did was go one step beyond and say, "OK, my customers want to see sex. I'll make it easier for them, and I'll categorize it." And I think what they realized afterward was that they were taking a far more active role in supplying this programming than just making it available. "Here's bestiality, here's whips and chains, here's whatever." That was going into probably more active participation by Yahoo than they really wanted to do.

Prayers don't help heart surgery patients.
In a clear setback for those who believe in the power of prayer, their prayers were not answered. Prayers offered by strangers did not reduce the medical complications of major heart surgery. Not only that, but patients who knew that others were praying for them fared worse than those who did not receive such spiritual support, or who did but were not aware of receiving it.Prayer is an illusion -- a video comparing the impact of praying to God versus praying to a jug of milk.

Patels
In the mid-1970's, Patels from Africa and Asia began to emigrate to North America. Any immigrant willing to invest $40,000 in a business could apply for permanent residence, the first step to citizenship. There were limited opportunities for such an investment. Restaurants required the Hindu Gujaratis to handle meat, an uncomfortable activity. Furthermore, a restaurant required one-on-one interaction with guests, confusing for newly-arrived immigrants. But distressed roadside motels could be acquired outright for $40,000.
Human Rights
But do democracies fares much better?
Two invasions of the Middle East were conducted by the world's most powerful democracy, which went on to flagrantly violate the Geneva Convention on treatment of prisoners of war domestically and internationally.
The world's most populous democracy fares no better.
Even Hitler was, to a certain extent, democratically elected.
What does this portend? Perhaps that human rights violations will continue as long as large powerful central states exist, whether democratic or not.

Democracy does not work in multi-ethnic societies...
[T]he result of the [World War I] crusade to make the world safe for democracy was less liberal than what had existed before (and the Versailles peace dictate precipitated World War II). Not only did state power grow faster after the war than before. In particular, the treatment of minorities deteriorated in the democratized post–World War I period. In newly founded Czechoslovakia, for instance, the Germans were systematically mistreated (until they were finally expelled by the millions and butchered by the tens of thousands after World War II) by the majority Czechs. Nothing remotely comparable had happened to the Czechs during the previous Habsburg reign. The situation regarding the relations between Germans and southern Slavs in pre-war Austria versus post-war Yugoslavia respectively was similar.Nor was this a fluke. As under the Habsburg monarchy in Austria, for instance, minorities had also been treated fairly well under the Ottomans. However, when the multicultural Ottoman Empire disintegrated in the course of the 19th century and was replaced by semi-democratic nation-states such as Greece, Bulgaria, etc., the existing Ottoman Muslims were expelled or exterminated. Similarly, after democracy had triumphed in the United States with the military conquest of the Southern Confederacy, the Union government quickly proceeded to exterminate the Plains Indians. As Mises had recognized, democracy does not work in multi-ethnic societies. It does not create peace but promotes conflict and has potentially genocidal tendencies.

Order from Anarchy
"The many rules strip us of the most important thing: the ability to be considerate. We're losing our capacity for socially responsible behavior," says Dutch traffic guru Hans Monderman, one of the project's co-founders. "The greater the number of prescriptions, the more people's sense of personal responsibility dwindles." ... Psychologists have long revealed the senselessness of such exaggerated regulation. About 70 percent of traffic signs are ignored by drivers. What's more, the glut of prohibitions is tantamount to treating the driver like a child and it also foments resentment. He may stop in front of the crosswalk, but that only makes him feel justified in preventing pedestrians from crossing the street on every other occasion. Every traffic light baits him with the promise of making it over the crossing while the light is still yellow.
