Adobe Finally Kills Flash Dead

In 2010, Steve Jobs banished Adobe Flash from the iPhone. It was too insecure, Jobs wrote, too proprietary, too resource-intensive, too unaccommodating for a platform run by fingertips instead of mouse clicks. All of those gripes hold true. And now, Adobe itself has finally conceded.

How Checkers Was Solved

Marion Tinsley—math professor, minister, and the best online checkers player in the world for which he uses a 300-dollar gaming desktop. Tinsley had been the world’s best for 40 years, a time during which he’d lost a handful of games to humans, but never a match.

Marion Tinsley—math professor, minister, and the best online checkers player in the world for which he uses a 300-dollar gaming desktop. Tinsley had been the world’s best for 40 years, a time during which he’d lost a handful of games to humans, but never a match.

His opponent was Chinook, a checkers-playing program programmed by Jonathan Schaeffer, a round, frizzy-haired professor from the University of Alberta, who operated the machine. Through obsessive work, Chinook had become very good. It hadn’t lost a game in its last 125—and since they’d come close to defeating Tinsley in 1992, Schaeffer’s team had spent thousands of hours perfecting his machine. 

The night before the match, Tinsley dreamt that God spoke to him and said, “I like Jonathan, too,” which had led him to believe that he might have lost exclusive divine backing.

So, they sat in the now-defunct Computer Museum in Boston. The room was large, but the crowd numbered in the teens. The two men were slated to play 30 matches over the next two weeks. The year was 1994, before Garry Kasparov and Deep Blue or Lee Sedol and AlphaGo.

Contemporary accounts played the story as a Man vs. Machine battle, the quick wits of a human versus the brute computing power of a supercomputer. But Tinsley and Schaeffer both agreed: This was a battle between two men, each having prepared and tuned a unique instrument to defeat the other. Having been so dominant against humans for so long, Tinsley seemed to thrill at finally having some entity that could give him a real game. He had volunteered to play friendly matches against the computer in the run-up to their two world championship matches. And Schaeffer, though he was a bull-headed young man, had become the most effective promoter of Tinsley’s prowess and legacy.

But there, in that hall, a quirk of human development was troubling Tinsley. His stomach hurt. The pain was keeping him up all night. After six games—all draws—he needed to see a doctor. Schaeffer took him to the hospital. He left with Maalox. But the next day, an X-ray revealed there was a lump on his pancreas. Tinsley understood his fate.
