Hard Drive Jenga A term used to describe removal of Hard Drives from a RAID storage array where the objective of the game is to remove as many drives as possible without the array collapsing causing catastrophic data loss.

Recently I noticed a distinct change in the sophistication of comment-spammers. The early comment-spammers were using very basic HTTP clients, mostly without thinking about what’s going on ‘under …
