Time again for our monthly news and events roundup, links from around the web.

Conferences and Seminars
ASCE International Conference on Sustainable Infrastructure, Nov 6-8
http://content.asce.org/conferences/icsi2014/index.html
Note the new focus of this conference: "This conference is not about how to be sustainable. If it were, we would tell you not to waste your time. Instead, and more appropriately, this conference is about how to deal with the consequences of non-sustainability, that is, how to plan, design and construct infrastructure for a new and increasingly harsh operating environment."
