Телефонная загадка
Пока был на конгрессе заехал к другу в Стэнфорд. За завтраком вычитал из его газеты, как израильтяне находили входы туннелей в Газе:
...Israeli spy agencies rely on information collection methods ranging from informants to technologies capable of sweeping up cellular and electronic communications in the Palestinian territories. Hamas countered that capability by wiring its longer tunnels with communications cables that weren't connected to the local telephone grid, the officials said. Israel could figure out the origin of some of the tunnels because diggers' cellphone signals would abruptly disappear when they went underground and then reconnect to the network hours later when they emerged, but that didn't indicate where the tunnels led, officials said.

Хитро придумано. Однако, если об этом сообщают в прессе, значит этот подход уже не работает. Интересно, как арабы догадались, по какому принципу ищут туннели. (Я бы никогда не додумался ни до того, ни до другого.)
