Faster websites with fewer bugs

Today, loading a web page on a big website usually involves a database query — to retrieve the latest contributions to a discussion you're participating in, a list of news stories related to the one you're reading, links targeted to your geographic location, or the like.

Study: Technological progress alone won’t stem resource use

Are humans taking more resources from the Earth than the planet can safely produce? The answer lies partly in whether we can “dematerialize,” or reduce the amount of materials needed to produce goods and services. While some scientists believe that the world can achieve significant dematerialization through improvements in technology, a new MIT-led study finds that technological advances alone will not bring about dematerialization and, ultimately, a sustainable world.
