By way of Heise Online comes word that Tor, the internet anonymization system, has hit a milestone of nearly mythical proportions -- there are currently no known bugs in the Tor code.

Tor began scanning its development releases in September using Coverity, a bug detection application developed by Stanford University in collaboration with the US Department of Homeland Security. In September, Coverity revealed 171 issues in Tor's code base, ranging from "annoying yet not critical" sloppiness to bugs capable of causing crashes that would prove challenging to debug. By December, Tor had lowered this number to 15, and last week, Coverity testing revealed that the project had successfully eliminated the last known issues.
