sabalaba — Sun, 15 Jan 2012 05:28:45 +0000

Here’s the math:

Facebook IPO: $100 billion valuation
Mark Zuckerberg’s ownership: 24% [0]
Value: 24 billion USD

Cost of the Mercury Project (to put a man into orbit around the earth)
Total: $392.6 million (1969 dollars) [1]

Present day cost of Mercury Project: $2.457 billion USD [2]

By selling 10% of his personal shares, he could finance his own personal space program.

You are going to die.

Few try to change the world during their brief tenure, fewer still try to change it for the better. Few step into the arena and spend themselves for a worthy cause. From the moment you come kicking and screaming into this world, you’re dying. By the time you’re “educated” with a college degree, you’re already 1/4 of the way out the door. What side of human progress are you?

It’s inspiring to know people like Alex Peake. We’re all capable of being catalysts of change in our environments; what have you done to change the world this month?

the begginnings of a game theory engine — axelrod’s tournament 2.0

Heres some work I threw together last night in preparation for doing an ICP in Computational Economics, I threw together a quick python script for having strategy bots wage repeated battle over programmable games. It sounds a lot more interesting than it really is.

Example Game:def prisoners():""" Prisoners Dilemma with delta = 0.95 """payoffs['discount'] = 0.95 payoffs['1, 1'] = (2,2) payoffs['1, 0'] = (0,3) payoffs['0, 1'] = (3,0) payoffs['0, 0'] = (1,1) return payoffs
