Have you ever heard the expression "a sepple a day keeps the Schemers away?" Most assume, with no reason to think otherwise, that it is simply an easy-to-remember rhyme that stresses the importance of learning C++ to young children. But the saying did not originate as a harmless reminder. It was born in a frontier datacenter in the early years of the computer industry, where storage was scarce and speed even scarcer.
One August, when a bad drought had struck the region, a series of bloody killings swept through the town. Every night, a single house would be broken into, and anyone who saw the invader would be swiftly, brutally slain. Nothing was ever stolen, save for a few floppy disks.
After two weeks of this, a local programmer set out a disk containing sepples source code and another with Scheme in the datacenter overnight. He then hid in the cabinet of one of the servers, hoping to catch a glimpse of anyone who came by.
Fighting fatigue, the programmer waited for any sign of life below. Just after midnight, he was rewarded by a chilling sight; a man, carrying a black snake with an evil grin and dully shining metallic-looking eyes and covered from head to foot in wizard's robes, staggered into view. He paused at the sight of the sepples and scheme disks, then whipped his head around, as if looking for the one who dared to patronize him. Seized with fear, the programmer ducked out of sight, staying hidden 'til sunrise.
The strange man had only taken one of the sepples, and didn't even touch the scheme disk. No houses were broken into, and no one was killed. For decades, the datacenter continued to place out a sepples disk or two every night, even long after a single sepples disk stopped dissapearing.

the same guy that taught you semantics, apparently.

The Sussman was once programming a tic-tac-toe game, and randomising his neural net, and an older man came over and asked him what he was doing. When he explained his code, the man asked why he was randomising his neural net.
The Sussman was baffled as to how he couldn't see why.
"I want to play the game against an AI with no preconceived notions of how to play."
The man looked more baffled.
The Sussman became confused, and started thinking over the concept for errors.
He found none.
The man shut his eyes.
The Sussman asked why.
The man said, "So the room will be empty."
It still has preconceived notions, YOU JUST DON'T KNOW WHAT THEY ARE!
With Satori and enlightenment gained, the man stood up, and handed the Sussman a python. The Sussman knew what to do. He broke off the python's fang, and shaped it into a lambda. And Scheme was pleased.

YOU CANNOT FIX A MACHINE BY POWERCYCLING IT IF YOU DO NOT KNOW WHAT THE ERROR IS.

Too many detection systems in this board, running up millions in cost. I vote we spend more on the SICP-awareness program that I brought forward in last week's meeting. All in favour?
