New York Times:  “As state after state has legalized marijuana in one way or another, big names in corporate America have stayed away entirely. Marijuana, after all, is still illegal, according to the federal government.  But Microsoft is breaking the corporate taboo on pot this week by announcing a partnership to begin offering software that tracks marijuana plants from “seed to sale,” as the pot industry puts it.  The software — a new product in Microsoft’s cloud computing business — is meant to help states that have legalized the medical or recreational use of marijuana keep tabs on sales and commerce, ensuring that they remain in the daylight of legality.
