Twitter Data Mining for Brand Sentiment

With heated political debates in the United States about the proposed southern border wall, I wanted to better understand how people living along the U.S./Mexico border really feel about the wall. Join my talk to learn how I used the Twitter API and R to mine tweets and tell the story of those populations closest to the border. I’ll walk through my code so you can use the same strategies to better understand the sentiment around your brand or service.

Tracking Low Energy Bluetooth Devices

How secure is your location while using a fitness tracker? One overlooked security issue is how wearables emit a persistent low energy Bluetooth signal exposing the device’s MAC address allowing anyone to track their location. Watch in horror or amusement how I easily set up a device to track the breakroom usage of my co-workers by tracking their Bluetooth devices.
