kruhft writes "I was recently doing some research into Genetic Programming and found a library through a blog post that looks to be useful. After looking over the code and license, I found that this was the first piece of code I had seen that was protected by a patent, issued on June 19, 1990. I read that patents last for 20 years, meaning that the patent that this code refers to is expired. Is there any way for me to be sure that using this code is safe from any patent troll attacks if I choose to use it? Would rewriting the code keep me from violating any other patents that the author might have regarding the use of such an algorithm?

It's taken four years for the ion thruster-propelled spacecraft to reach the asteroid and there was some uncertainty as to whether the probe had been captured by the asteroid's gravity at all. But after a long period of waiting, mission managers received the signal after Dawn was able to orientate its antenna toward Earth."

Barbara, not Barbie writes "Not content with making it hard for people to export their Facebook contacts to Google+, Facebook has now banned all ads from app developer Michael Lee Johnson, who ran an ad saying 'Add Michael to Google+.' Facebook sent him the following message: 'Your account has been disabled. All of your adverts have been stopped and should not be run again on the site under any circumstances. Generally, we disable an account if too many of its adverts violate our Terms of Use or Advertising guidelines. Unfortunately we cannot provide you with the specific violations that have been deemed abusive. Please review our Terms of Use and Advertising guidelines if you have any further questions.'"

An anonymous reader writes "Google has reportedly banned a handful of Anonymous members from Google+ (it's not exactly clear how many accounts were shut down). The hacktivist group likened Google's actions to the stories of activists being banned from Facebook, Twitter, YouTube, as well as governments blocking various websites using Internet censorship tools. As a result, Anonymous has decided to create its own social network: Anonplus."
