When Google and Sun said they would make a common announcement in a public webcast, technical blogs all around started crank up speculations about what that announcement would be. And with Google in there, it had to be something big. What Google and Sun finally announced yesterday will not change... More

At the end of last week, we moved our main office in California from Mountain View to San Mateo. If moving furniture was not fun enough, we also had to move our server rack. This has caused some downtime of our servers, including our email, and of course we have... More
