  1. This kind of topic always get a butt-load of posts. Having done my own research for the last year or so, I am personally convinced that AGW is sheer nonsense. The IPCC is cracking under the strain of their wacky, unscientific projections, and folks are beginning to realize the sham and scam of the AGW alarmists. Almost daily we hear about yet another peculiar prophesy based on skewed or zero data. No I am not a right-winger or fundamentalist ranting against science in general. In fact, I’m an atheist, pro choice, and an advocate of gay rights across the board, as well and fetal stem cell research, etc.

  2. This is working for me from the command line

    sudo /usr/libexec/PlistBuddy -c “Add :ProgramArguments:2 string ‘-NoMulticastAdvertisements'” /System/Library/LaunchDaemons/
