Work Smarter not Harder - We have large data sets in my current project. Every year tons more data is loaded into the system. So we only keep the majority of data for 4 years. After...
They interviewed one of his opponents. The opponent was some sort of kid grand master at chess. He said that when he played this high school kid, he was hanging on for dear life due to the aggressive onslaught of attacks on the chess board. How could a kid rise up in chess skill so fast. Well it turns out the boy was cheating.
The chess rules allow you to bring in a PDA to record your chess rules. You are only allowed to run a certain chess move recording program. That program has been certified as being able to take over the PDA and ensure no other programs (that might be used to cheat) are running. Turns out this kid was somehow able to get around it.
What should have been suspicious is a kid with just a good rating all of a sudden starts playing like he is Bobby Fischer. That just does not happen. They also interviewed some of this kid's previous coaches. They knew he was okay, but nothing like a Bobby Fischer. In fact, a past opponent had complained that it felt as if the dude was cheating. They just could not find any evidence of it before.
In the end, a judge was called into the state competition match, took possession of the PDA, and found a rogue program being run. Here is the funny part of the story. The kid said this was the first time he cheated. Yeah right. The moral of the story is to trust but verify.
