As one of the world's largest gatherings of hackers, the Def Con conference has long welcomed experts from the security industry and the U.S. government, along with academics and hackers. But this year, Def Con's leader is asking federal workers to skip the event, due to recent revelations about U.S. electronic surveillance.
The request was announced Wednesday in a message titled, "Feds, we need some time apart," which was posted at the Def Con site. It reads:
This year, the NPR Cities Project is covering the concept of "smart cities": how cities worldwide are experimenting with technology to solve all sorts of urban problems. Please join us as we tackle the issue of smart cities with a live Twitter chat on Thursday, July 11, from 11 a.m. to 12 noon EDT.
Policymakers hope implementing technological solutions to urban issues will help cities become more efficient, more user-friendly and more environmentally sustainable.
