Materials for the COVID-19 and Climate Change Action Through Open Source Technology keynote at DeveloperWeek on June 16, 2020 https://www.developerweek.com/global/ Call for Code a five-year program that inspires developers to create practical, effective, and high-quality applications that can have an immediate and lasting impact on humanitarian issues as sustainable open source projects. Building on the success of the 2018 and 2019 competitions, the Call for Code 2020 Global Challenge asks teams of programmers, data scientists, designers, business analysts, subject matter experts, and more to build solutions that significantly address climate change through solutions for energy and water sustainability and disaster resiliency. A second track was added for solutions to the social and business aspects of COVID-19 which include crisis communications, remote education, and community cooperation. Learn about this year's Call for Code Challenge (which has a top prize of $200K USD), be inspired by the 2018 and 2019 winners (Project OWL and Prometeo), and discover the new Code and Response™ with The Linux Foundation initiative which supports the most promising solutions.
