+ - Gartner report throws cold water on uber-hyped OpenStack project->

Submitted by alphadogg
alphadogg (971356) writes "A scathing report about OpenStack from research firm Gartner warns businesses to beware of considerable hype and says misconceptions about the open source cloud computing project are leading to "dangerous myths" that are impacting IT adoption and investments. OpenStack is a nascent technology driven by a group of self-serving vendors who are pushing their own agendas over the usability of the cloud management platform, argues Lydia Leong, the author of the report and a research VP at Gartner who focuses on cloud computing. As OpenStack hype continues to build, she says vendors are associating themselves with the project for marketing reasons, but are reticent about contributing significant resources to the broader goals of the project. OpenStack backers naturally disagree, and issued point-by-point counterarguments."

+ - To Encourage Biking, Lose the Helmets 2

Hugh Pickens writes
Hugh Pickens writes writes "Elisabeth Rosenthal writes that in the United States the notion that bike helmets promote health and safety by preventing head injuries is taken as pretty near God’s truth but many European health experts have taken a very different view. "Yes, there are studies that show that if you fall off a bicycle at a certain speed and hit your head, a helmet can reduce your risk of serious head injury," writes Rosenthal. "But such falls off bikes are rare — exceedingly so in mature urban cycling systems." On the other hand, many researchers say, if you force people to wear helmets, you discourage them from riding bicycles causing more health problems like obesity, heart disease and diabetes. Bicycling advocates say that the problem with pushing helmets isn’t practicality but that helmets make a basically safe activity seem really dangerous. which makes it harder to develop a safe bicycling network like the one in New York City, where a bike-sharing program is to open next year. The safest biking cities are places like Amsterdam and Copenhagen, where middle-aged commuters are mainstay riders and the fraction of adults in helmets is minuscule. “Pushing helmets really kills cycling and bike-sharing in particular because it promotes a sense of danger that just isn’t justified — in fact, cycling has many health benefits,” says Piet de Jong. “Statistically, if we wear helmets for cycling, maybe we should wear helmets when we climb ladders or get into a bath, because there are lots more injuries during those activities.”"
