Sinkholes Usually Don't Kill
Firemen secure the perimeter of a sinkhole that left a huge crater in the middle of a residential area in Schmalkalden, Germany, Nov. 1, 2010. No one was hurt. The hole was about 20 meters (66 feet) deep.

Sinkholes are a common feature in Florida's limestone-rich bedrock as groundwater easily dissolves the calcium carbonate into solution turning the ground into a slushy mix that washes out under the structures built on top of it.
But rarely do they kill.
On Thursday night, a sinkhole in Tampa opened up and swallowed the bedroom where Jeffrey Bush, 37, was sleeping. Rescue crews and his brother acted quickly to try and save him, but Friday morning, listening devices and cameras placed in the hole failed to pick up any signs of life.

Top 10 Most Common Cyber Attacks Denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks A denial-of-service attack overwhelms a system’s resources so that it cannot respond to service requests. A DDoS attack is also an attack on system’s resources, but it is launched from a large number of other host machines that are infected by malicious software controlled by the attacker. Unlike attacks that are designed to enable the attacker to gain or increase access, denial-of-service doesn’t provide direct benefits for attackers.
