One Christmas Eve, a frenzied...

One Christmas Eve, a frenzied young man ran into a pet shop looking for an unusual Christmas gift for his wife. The shop owner suggested a parrot, named Chet, which could sing Christmas carols. This seemed like the perfect gift.
"How do I get him to sing?" the young man asked excitedly.
"Simply hold a lighted match directly under his feet," was the shop owner's reply.
The shop owner held a lighted match under the parrot's left foot. Chet began to sing: "Jingle Bells! Jingle Bells!" The shop owner then held another match under the parrot's right foot. Chet's tune changed, and the air was filled with: "Silent Night, Holy Night..."
The young man was so impressed that he paid the shop-keeper and ran home as quickly as he could with Chet under his arm. When the wife saw her gift she was overwhelmed.
"How beautiful!" she exclaimed. "Can he talk?"
"No," the young man replied, "but he can sing. Let me show you."
So the young man whipped out his lighter and placed it under Chet's left foot, as the shop-keeper had shown him, and Chet crooned: "Jingle Bells! Jingle bells!..."
The man then moved the lighter to Chet's right foot, and out came: "Silent Night, Holy night..."
The wife, her face filled with curiosity, then asked, "What if we hold the lighter between his legs?"
The man did not know. "Let's try it," he answered, eager to please his wife. So they held the lighter between Chet's legs.
Chet twisted his face, cleared his throat, and the little parrot sang out loudly like it was the performance of his life: "Chet's nuts roasting on an open fire...."

Computer chess

In 1996, world chess champion Gary Kasparov defeated Deep Blue, IBM's chess-playing computer, by winning a six-game match 4-2, in a regulation-style match held in Philadelphia, as part of the ACM Computer Science Conference. Deep Blue is an improved version of the older Deep Thought, augmented by parallel special-purpose hardware. Deep Blue uses a selectively deepening search strategy, using improvements of the alpha-beta search strategy, with powerful evaluation functions. Transposition tables help avoid unnecessarily calculating the same position more than once. Two powerful databases further augment Deep Blue's play. Deep Blue would defeat Kasparov - the first time the grandmaster ever lost a six-game match in championship play.
