In late 2000, the producers and crew for action flick Rush Hour 2 gathered at the now-defunct Desert Inn in Las Vegas and prepared to blow up a casino. The scene, which pitted policemen and Secret Service agents against a counterfeiter attempting to launder $100 million in superdollars, was to culmi…

"Even though I managed to bring in a paltry $498 for a year's worth of side-project time, it gets even worse. I paid nearly $700 in Facebook and Twitter mobile ads to try and market them.

On January 25, 1995, at 9:28 A.M. Moscow time, an aide handed a briefcase to Boris Yeltsin, the President of Russia. A small light near the handle was on, and inside was a screen displaying information indicating that a missile had been launched four minutes earlier from somewhere in the vicinity of…
"And so, for six minutes in 1995, the future of the species hung in the balance because a mid-level Russian official left work early, or neglected to find a proper procedure for dealing with a message that someone was sending up a rocket, at an unspecified time, to look at the northern lights. It’s like the forty-six-cent computer chip. There was no redundancy built into the system. If one piece failed, the whole system was imperilled."
Markov chains, named after Andrey Markov, are mathematical systems that hop from one "state" (a situation or set of values) to another.

"I have often reflected upon the new vistas that reading opened to me. I knew right there in prison that reading had changed forever the course of my life. As I see it today, the ability to read awoke inside me some long dormant craving to be mentally alive. I certainly wasn’t seeking any degree, the way a college confers a status symbol upon its students. My homemade education gave me, with every additional book that I read, a little bit more sensitivity to the deafness, dumbness, and blindness that was afflicting the black race in America. Not long ago, an English writer telephoned me from London, asking questions. One was, “What’s your alma mater?” I told him, “Books.” You will never catch me with a free fifteen minutes in which I’m not studying something I feel might be able to help the black man."

Fred Fletcher doesn’t watch baseball anymore, but one night in May, he got a text from a friend: Something had happened at that evening’s
"How fast was it going? We don’t know for sure, but a line drive from a major league batter can easily exceed 100 miles per hour. We know some other things. We know that a baseball weighs five ounces. We know that force equals mass times acceleration. We know that Fred Fletcher’s six-year-old daughter, whom he will identify only as “A,” was sitting precisely 144 feet from home plate. The laces on her sneakers were knotted in neat bows. And she—well, not just she, but everyone around her—had less than one second to react to Cabrera’s line drive."

"That's really surprising, especially realizing that this applies for all NP-hard problems, if formulated correctly. So, simply choosing a random solution is often effectively as good as the best approximation algorithms that are currently known. In fact, in our paper we linked above we present some empirical evidence suggesting that the random solutions are often even closer to optimal than ones produced by state-of-the-art approximation algorithms."

Fifty percent off? That doesn't sound like such a good deal for sushi or a college degree. We ask some economists: Why not?
"Unfortunately, there's a real world impact here. In recent years there's been a lot of attention to the issue of undermatching. This is the finding that a majority of highest-achieving but low-income students fail to apply to a single competitive college. Even when financial need means that they would pay little or nothing to attend a school like Harvard or Stanford, these students are instead choosing non-selective schools that tend to have a lower advertised price."

If you think that just having a knife will make you win any battle you fight, then you will fail. This believe in your own inherent ability is what will kill your startup.

"But Linus' [Torvalds] observation that "95 percent of all programmers think they are in the top 5 percent, and the rest are certain they are above average" should not be taken lightly: very few programmers have any idea what the difference is between "wall-clock time" and "interval time," and leap seconds are way past rocket science for them. (For example, Posix defines only a pthread_cond_timedwait(), which takes wall-clock time but not an interval-time version of the call.)"
