It’s mentioned here:
Mr. Doerr said he had been wearing the glasses and uses them especially for taking pictures and looking up words while playing Scattergories with his family, though it is questionable whether that follows the game’s rules.
Questionable? Questionable? It’s just like using a computer’s dictionary while playing Scrabble, or a computer odds program while playing poker, or a computer chess program while playing an in-person game. There’s no question at all — it’s cheating.
We’re seeing the birth of a new epithet, “glasshole.”
How international soccer matches are fixed.
Right now, Dan Tan’s programmers are busy reverse-engineering the safeguards of online betting houses. About $3 billion is wagered on sports every day, most of it on soccer, most of it in Asia. That’s a lot of noise on the big exchanges. We can exploit the fluctuations, rig the bets in a way that won’t trip the houses’ alarms. And there are so many moments in a soccer game that could swing either way. All you have to do is see an Ilves tackle in the box where maybe the Viikingit forward took a dive. It happens all the time. It would happen anyway. So while you’re running around the pitch in Finland, the syndicate will have computers placing high-volume max bets on whatever outcome the bosses decided on, using markets in Manila that take bets during games, timing the surges so the security bots don’t spot anything suspicious. The exchanges don’t care, not really. They get a cut of all the action anyway. The system is stacked so it’s gamblers further down the chain who bear all the risks.
With over a thousand cameras operating 24/7, the monitoring room creates tremendous amounts of data every day, most of which goes unseen. Six technicians watch about 40 monitors, but all the feeds are saved for later analysis. One day, as with OCR scanning, it might be possible to search all that data for suspicious activity. Say, a baccarat player who leaves his seat, disappears for a few minutes, and is replaced with another player who hits an impressive winning streak. An alert human might spot the collusion, but even better, video analytics might flag the scene for further review. The valuable trend in surveillance, Whiting says, is toward this data-driven analysis (even when much of the job still involves old-fashioned gumshoe work). “It’s the data,” he says, “And cameras now are data. So it’s all data. It’s just learning to understand that data is important.”
There’s a fascinating story about a probable tournament chess cheat. No one knows how he does it; there’s only the facts that 1) historically he’s not nearly as good as his recent record, and 2) his moves correlate almost perfectly with one of best computer chess programs. The general question is how valid statistical evidence is when there is no other corroborating evidence.
In the case of that student, the professor in the course had tried to prevent cheating by using a testing system that pulled questions at random from a bank of possibilities. The online tests could be taken anywhere and were open-book, but students had only a short window each week in which to take them, which was not long enough for most people to look up the answers on the fly. As the students proceeded, they were told whether each answer was right or wrong.
Mr. Smith figured out that the actual number of possible questions in the test bank was pretty small. If he and his friends got together to take the test jointly, they could paste the questions they saw into the shared Google Doc, along with the right or wrong answers. The schemers would go through the test quickly, one at a time, logging their work as they went. The first student often did poorly, since he had never seen the material before, though he would search an online version of the textbook on Google Books for relevant keywords to make informed guesses. The next student did significantly better, thanks to the cheat sheet, and subsequent test-takers upped their scores even further. They took turns going first. Students in the course were allowed to take each test twice, with the two results averaged into a final score.
“So the grades are bouncing back and forth, but we’re all guaranteed an A in the end,” Mr. Smith told me. “We’re playing the system, and we’re playing the system pretty well.”
