• Can Firefox Plugin, Greasmonkey, be detected by Web Servers?

  - by Babar

  Hi, My friend's account for some Facebook game was suspended on the grounds that he had Greasemonkey installed on his browser. He is asked to uninstall Greasemonkey and account has been restored. My question is how can a web server detect a client side plugin presence? I assume that Greasemonkey or greasemonkey scripts operate on the client side only so it would not be possible for the server to detect it. Thanks.

How do I A) know where hadoop is writing to on the local disk and B) change that For initial testing I setup HDFS on a 20gb linux VM - to it we've added a 500gb networked drive for moving towards prototyping the full system.
