AcidAUS sends us the story of an online poker cheating ring that netted an estimated $10M for its perpetrators over almost 4 years. The article spotlights the role of an Australian player who first performed the statistical analyses that demonstrated that cheating had to be going on. "In two separate cases, Michael Josem, from Chatswood, analyzed detailed hand history data from Absolute Poker and UltimateBet and uncovered that certain player accounts won money at a rate too fast to be legitimate. His findings led to an internal investigation by the parent company that owns both sites. It found rogue employees had defrauded players over three years via a security hole that allowed the cheats to see other player's secret (or hole) cards." The (Mohawk) Kahnawake Gaming Commission, which licenses the two poker companies, has released its preliminary report. MSNBC reporting from a couple of weeks back gives deep background on the scandal.

The technique '[combines] wireless signal models with publicly-available information about basic topography, street locations, and land use.' This enables Wi-Fi architects to test and refine their layouts cheaply before a network is deployed by focusing measurement efforts on areas that potentially could be dead zones. The technique requires only about one-fifth as many measurements as a grid sampling strategy."
