The first thing you need to know about the Internet is that it is amazing
Oh man, I could not stop laughing at this old “Kids Guide to the Internet” video from the 90s. My thanks to my former colleague Amy Smorodin for tweeting it out today. I just had to post it here so that everyone could enjoy.
(Note: You can turn this video into a great drinking game. Just make everyone in the room raise their glass each time the lines “Does your computer have a modem?” and “Not all that cybernet stuff, OK?” are uttered.) And yes, as the opening line of the video notes, “the first thing you need to know about the Internet is that it is amazing.”

Apple made waves this morning when it announced its oft-rumored September 10 event, but Google isn’t giving up the day’s limelight without a fight — according to a post on Sundar Pichai’s Google+ page, over one billion Android devices have been activated to date.
Bluffing still matters, but the best players now depend on math theory
The World Series of Poker, 2010.
This growth over the past decade has been accompanied by a profound change in how the game is played. Concepts from the branch of mathematics known as game theory have inspired new ideas in poker strategy and new advice for ordinary players. Poker is still a game of reading people, but grasping the significance of their tics and twitches isn’t nearly as important as being able to profile their playing styles and understand what their bets mean.
In no-limit hold’em poker, the game used for the World Series championship, each player is dealt two private cards and attempts to make the best five-card hand that he can by combining his own cards with five cards that are shown faceup and shared by all players. Those cards are revealed in stages: The first three are the “flop,” the fourth is the “turn,” and the fifth is the “river.” Players can bet any amount they like at each stage.
Suppose you hold a pair of sevens, and before the flop is dealt you go all-in (bet all of your chips). One player calls your bet, and everyone else folds their hands. You both turn your cards face up, and you are happy to see your opponent show a pair of sixes. You are in great shape, since you have the better hand. But when the flop arrives, it contains a six, giving your opponent three sixes, and your own hand doesn’t improve, so you lose. Was your all-in play correct?
In terms of results, it wasn’t, because you lost all your chips. But according to the math of hold’em, a pair of sevens is favored to beat a pair of sixes 81% of the time. So if you can go all-in with sevens and get your bet called by players holding sixes over and over again, luck should even out, and eventually you will be a big winner.
