Melugo writes to let us know that Russian president Vladimir Putin has warned that US plans to build a missile defense system in Eastern Europe would force Moscow to target its weapons against Europe. This reader notes: "It feels like the Cold War all over again." "'If the American nuclear potential grows in European territory, we have to give ourselves new targets in Europe,' Putin said... 'It is up to our military to define these targets, in addition to defining the choice between ballistic and cruise missiles.'"

sighted writes "The New Horizons probe, on its way to Pluto and beyond, is now speeding toward Jupiter. Today the team released some of the early data and pictures, which are the first close-range shots of the giant planet since the robotic Cassini spacecraft passed that way in 2001."

Virtual_Raider writes "Wired is carrying a story about a method developed by security researchers to identify computers hiding behind anonymity services. From the article: 'His victim is the Onion Router, or "Tor" — a sophisticated privacy system that lets users surf the web anonymously. Tor encrypts a user's traffic, and bounces it through multiple servers, so the final destination doesn't know where it came from. Murdoch set up a Tor network at Cambridge to test his technique, which works like this: If an attacker wants to learn the IP address of a hidden server on the Tor network, he'll suddenly request something difficult or intensive from that server. The added load will cause it to warm up.'"
