The old town area of Tallinn, Estonia, is dotted with medieval buildings that reflect its long history. But the city has placed great emphasis on high-tech since the country broke away from the Soviet Union two decades ago.
The Baltic city of Tallinn hardly looks modern with its blend of medieval towers and Soviet-era architecture. Smoke-spewing buses and noisy streetcars look as if they have been plucked from the past.
Even so, the Estonian capital is one of the world's most technologically advanced cities. The birthplace of Skype has repeatedly been cited for its digital accomplishments. Last week, Tallinn once again made the short list of the world's most intelligent cities as selected by the Intelligent Community Forum.
If you're a member of Congress and you didn't know about the National Security Agency's phone records program before it was disclosed last week, President Obama has this to say to you: Where have you been?
"When it comes to telephone calls, every member of Congress has been briefed on this program," Obama said to reporters last Friday.

Millions of bats emerge from Bracken Cave, near San Antonio, in 2011. The cave is located in a rural area, but conservationists are worried that a planned housing development nearby will disturb the bat colony that lives here.
The Bracken Bat Cave, just north of San Antonio, is as rural as it gets. You have to drive down a long, 2-mile rocky road to reach it. There's nothing nearby — no lights, no running water. The only thing you hear are the katydids.
The cave houses a massive bat colony, as it has for an estimated 10,000 years. Bat Conservation International, the group that oversees the Bracken Cave Reserve, wants it to stay secluded, but the area's rural nature could change if a local developer's plan moves forward.
Reaction was swift to the Obama administration's announcement Monday night that it was dropping a long-running legal battle to keep age restrictions on one type of the morning-after birth control pill.
But like just about everything else in this decade-long controversy, the latest decision has pleased just about no one.

The equipment hanging from the Customs and Border Protection drone's underbelly includes a night camera, a day camera, a low-light camera and laser target illumination.
The runways at Fort Huachuca, Ariz., are busy. This is where the Army tests its military drones, where it trains its drone pilots, and where four Customs and Border Protection drones take off and land.
From here, the CBP drones survey the Arizona-Mexico border — mainly looking for immigrants and drug smugglers.
