Video: Sustainable IT guru Ted Samson speaks with Judy Glazer, Hewlett-Packard’s director of global operations and environmental responsibility, about the ways HP benefits from keeping a close eye on how its suppliers are environmentally and socially responsible, how HP meets regulations, and the business case for a green supply chain and green IT in general. Watch it here. Best of the blogs: That’s not all from Mr. Samson, either. He also delves into Strategic steps down the green IT path. The first move, as in so many projects, is to identify and prioritize goals. “That task in and of itself can demonstrate just how complex a green transformation can be,” Samson explains. “Tempting as it may be to start throwing resources around to reap rewards of sustainability, planning, assessing, monitoring and procedural changes are critical — and IT has a central role to play in it all.” Tech’s bottom line: Forget today’s ticker, Bill Snyder advises. “Tech companies are showing strength across multiple sectors.” IT’s rational exuberance. Software is still a mixed bag, to be sure, but chipmakers, outsourcers, e-commerce companies, PC makers, and so on are issuing solid reports. Even still, “the volatility has been rather amazing,” Synder writes of Amazon’s bump then dip. “Tech’s losses have been largely caused by larger worries about the credit crunch and its parent, the sub-prime mortgage meltdown. I’d be sweating a lot more if I didn’t see solid sales and earnings by the major players.” Columnist’s corner: It’s been two years in the making but Total system disruption, part 2 is here. The original focused on Hurricane Katrina and the ensuing anarchy, arguing for smarter predictive modeling for human response to natural disasters. “Today I sit watching as a million-plus people stream out of San Diego County, fleeing a totally foreseeable chain of extreme firestorms,” David Margulius explains. “Every-man-for-himself planning and predictive modeling is not enough anymore. We need a nationwide early-warning data-modeling platform that can be shared by industry and leveraged by the private and public sectors, as well as the military.” Related: Katrina’s total system disruption.
