Many ad networks[1] do already provide an opt out mechanism. You look for a blue icon[2] in the corner of the ad, which if you click it should take you to an opt out page.

I dug a bit further, and also found this: http://www.aboutads.info/choices/ which purports to allow you to opt out from any or all of the participating companies from that page.

This part jumped out at me:

"As a solution, Gelernter proposes moving all of human knowledge to online servers so that the in-person college experience can be replaced by user-driven self-education."

They plan to launch food supplies to Mars in 2016, 7 years before sending the astronauts and 2 years before they've even scouted out where to establish a settlement.

I don't understand why they would send the supplies there so early. Can anyone explain this timeline to me?
