We're now entering the third week of Google's Treasure Hunt competition, a puzzle contest designed to test your knowledge of computer science, networking, and low-level UNIX trivia. Last week we posted the second puzzle. This week's puzzle is set to be released on Tuesday, May 27 at 10 a.m. PDT. We'll also be featuring our brand-new San Francisco office along with it.

We'll be giving out a few prizes for the fastest contestants to complete each question. There will also be a grand prize for the contestant who correctly answers all four questions in the shortest cumulative time (time is defined as the time between the question's release and the submission of the correct answer). The previous puzzles will still be accessible off of the main page.

The treasure is within reach, so grab yer shovels and keep on diggin', mateys!
