Buck – A build system developed and used by Facebook
Continuing the trend of Facebook creating competing tools more often than persisting with and improving existing ones, which I feel dilutes effort and has fragmented a number of ecosystems.We've got a couple of Facebook fans at work, which has left us with a number of our systems using different tools to accomplish essentially the same tasks, and no strong case on either side for us to standardise on one of them.Maybe I'm just being bitter because I've had a bad experience, but it's been a maintenance nightmare for us in the office.
