 Hi, I'm Brianna Frank. I am the director of product here at IBM Cloud, and I'm so honored today to talk to you about the call for code challenge. Over the past three years, call for code has proven one simple truth. Teams of developers with the right mindset, the right technology, and the right deployment ecosystem have the power to solve some of the world's greatest problems. Call for code is a movement started by four organizations motivated to use technology for good. Unlike other tech for good challenges, call for code does not just award a prize and send everyone home. Call for code is committed to deploying solutions and to ensure they live on in strong open source projects anyone can use or improve. Call for code has inspired participants from around the world to learn new skills and to apply them towards the issues that affects them most, regardless of their experience, thanks to tools from the open source community. Over the years, call for code has asked for technology solutions to a variety of pressing, social, environmental, and justice issues with challenges formulated by bringing technologists together with domain experts. By helping developers know how they can solve important issues and develop a solution that makes a real impact. We've seen amazing creativity, and we've supported their testing and deployment around the world. In an effort to tackle specific elements of climate change that are of high priority, the call for code challenge announced three focus areas to tackle in this year's global challenge, clean water and sanitation, zero hunger, and responsible production. Let's take a look at some of the previous winning solutions. Open EEW saves lives with an earthquake early warning system. Open EEW has deployed a set of low-cost accelerometer-based devices to detect tremors. Data is collected and processed using Kubernetes and generates alerts to nearby residents. This open source-based system provides a way for communities without a full national seismology system to gain access to life-saving technology. The next example is Prometeo. As wildfires and other natural disasters become more prevalent around the world, Prometeo protects the health of firefighters. Prometeo created a device containing sensors for the toxic chemicals that firefighters are repeatedly exposed to. A Kubernetes cluster hosts several microservices that interpret the IoT readings, calculate long-term analytics, and push alerts back to ruggedized Samsung mobile phones and smartwatches. This cognitive platform measures toxin levels in real time and sends color-coded alerts to keep firefighters safe. And finally, Project Al. Project Al provides critical communication in times of natural disasters. Hurricane Maria, a Category 5 hurricane at Puerto Rico and wrecked Havoc on the island. Not only did it destroy people's homes, but also people's way of communicating. Cell towers and generators were destroyed. Project Al provides a system for quickly deploying emergency mesh networks for short but critical communication. Their dashboard is based on Cloud Foundry today. But they're exploring using Kubernetes for edge-based devices and IBM Cloud Code Engine for faster development of containerized apps. Are you ready to answer the call? The technologies we are building together with CNCF can be used to make a huge difference in the world. Call for Code is also a fantastic opportunity to learn new technologies, including IBM Cloud Code Engine.
