441. Does Advertising Actually Work? (Part 2: Digital)
Play • 48 min

Google and Facebook are worth a combined $2 trillion, with the vast majority of their revenue coming from advertising. In our previous episode, we learned that TV advertising is much less effective than the industry says. Is digital any better? Some say yes, some say no — and some say we’re in a full-blown digital-ad bubble.

AI in Contact Tracing and Data Privacy
When it comes to fighting infectious disease outbreaks, contact tracing is a key public health response. Mobile technologies including GPS, Bluetooth, cellphone masts and AI-powered big data analytics, can help collect data that helps decision-makers understand and manage the spread of pandemics like COVID-19 within their own communities.   But when using this kind of technology, it’s critical to preserve personal privacy to not only maintain public trust but especially to protect vulnerable individuals during a crisis. This episode explores how privacy-preserving techniques such as homomorphic encryption and solutions for mobile phone contact tracing can be deployed, including real-world examples from Israel and the US. Today’s episode was originally recorded at AI For Good, an annual global summit hosted by ITU and XPRIZE, and while some elements of the conversation are more timely to COVID’s spread in April 2020 at the time of recording, our guests discuss explore how developers are creating tracing software, its importance in early response efforts and technical specifics, all of which are especially relevant challenges still today.   Thomas Wiegand is a German electrical engineer who substantially contributed to the creation of the H.264/MPEG-4 AVC and H.265/MPEG-H HEVC video coding standards. For H.264/MPEG-4 AVC, Wiegand was one of the chairmen of the Joint Video Team (JVT) standardization committee that created the standard and was the chief editor of the standard itself. He was also an active technical contributor to both standards. Wiegand also holds a chairmanship position in the ITU-T VCEG and previously in ISO/IEC MPEG standardization organizations. In July 2006, the video coding work of the ITU-T jointly led by Gary J. Sullivan and Wiegand for the preceding six years was voted as the most influential area of the standardization work of the CCITT and ITU-T in their 50-year history. Wiegand is Professor at the Technical University of Berlin and executive director of the Fraunhofer Heinrich Hertz Institute, Berlin, Germany. He heads research teams working on : Video processing and coding, Multimedia transmission, Machine learning, Mobile Communications (management) and Computer Vision (management). Kurt Rohloff is the co-founder and CTO of Duality Technologies, a technology start-up enabling privacy-preserving analytics and collaboration on sensitive data. He leads the development of PALISADE, an open source homomorphic encryption software library that encrypts data so that they can be safely used for predictive analytics while preserving private information. Prior to co-founding Duality he was a professor of computer science at the New Jersey Institute of Technology. He received his PhD from the University of Michigan. He is the recipient of a DARPA Director’s Fellowship.   Links:  https://dualitytech.com/  https://aiforgood.itu.int/  xprize.org/blog See acast.com/privacy for privacy and opt-out information.

Watt It Takes: BlocPower CEO Donnel Baird
BlocPower CEO Donnel Baird is on a mission to clean up old, inefficient buildings in America’s cities -- and help people who are exposed to the worst pollution.  BlocPower was founded in 2012. It’s raised venture capital from Kapor Capital and Andreesen Horowitz. But that process was not easy for a company with a mostly non-white leadership team. As a black founder, Donnel was turned down 200 times before any venture firms were willing to back his vision. “It was really difficult for us raising capital. One of our investors when I talked to him two or three years ago and said I was struggling to raise capital, he was like ‘yeah man, just hire some white people and send them into the fundraising meetings and it’ll clear things up,’” explains Donnel. BlocPower is a Brooklyn, New York startup electrifying and weatherizing buildings in underserved communities -- slashing pollution and saving money. This includes housing units, churches, community centers.  And the mission for Donnel isn’t about just about hitting milestones for investors. It’s about changing the fabric of underserved communities that are plagued by pollution and energy poverty. That’s because Donnel has lived it himself. In this episode, Powerhouse CEO Emily Kirsch talks with Donnel about how he channeled his frustration and anger around racial unfairness into a business model for the energy transition. Listen to all our past episodes of Watt It Takes here. This series is normally recorded in front of a live audience, but we’re now recording the interviews remotely. See future events from Powerhouse here. The Energy Gang is brought to you by Sungrow, a leading provider of PV inverter solutions across the world. Sungrow has delivered more than 10 gigawatts of inverters to the Americas alone -- and 120 gigawatts in total across the globe. Learn more about Sungrow’s cutting-edge solar projects. The Energy Gang is also brought to you by CPower. CPower and its team of energy experts are back with a webinar series aimed to help organizations make sense of the chaos and optimize their energy use and spend in 2021.
