Ever stare at the barest pieces of concrete and metal preventing you from veering off a bridge and plummeting hundreds of feet to your watery grave below, and wondering how they test all that? Me neither, let’s be honest. But if you did, it’s exactly how you think they’d do it. By crashing big stuff into it. » 5/06/15 5:00pm 5/06/15 5:00pm

​Our 'Smart' Cities Are Ridiculously Insecure

Cities from Los Angeles to Seoul are pouring billions of dollars into smartifying infrastructure, networking everything from traffic lights to waste management systems.

For vast majority of the year, the only way to reach remote but lucrative gold and diamond mines in Canada's northwest is by air. But every winter, something crazy happens.
