M3, a metrics platform, and M3DB, a distributed time series database, were developed at Uber out of necessity. After using what was available as open source and finding we were unable to use them at our scale due to issues with their reliability, cost and operationally intensive nature we built our own metrics platform piece by piece. We used our experience to help us build a native distributed time series database, a highly dynamic and performant aggregation service, query engine and other supporting infrastructure.

Haven is for people who need a way to protect their personal areas and possessions without compromising their privacy. It is an Android application that leverages on-device sensors to provide monitoring and protection of physical areas. Haven turns any Android phone into a motion, sound, vibration and light detector, watching for unexpected guests and unwanted intruders. We designed Haven for investigative journalists, human rights defenders and people at risk of forced disappearance to create a new kind of herd immunity. By combining the array of sensors found in any smartphone, with the world's most secure communications technologies, like Signal and Tor, Haven prevents the worst kind of people from silencing citizens without getting caught in the act.

The climate crisis isn’t a future we must fight to avoid. It’s an already unfolding reality. It’s the intensification of extreme weather–cyclones, storms and floods, droughts and deadly heat waves. It’s burning forests in Australia, the Amazon, Indonesia, Siberia, Canada and California. It’s melting ice caps, receding glaciers and rising seas. It’s ecosystem devastation and crop failures. It’s the scarcity of resources spreading hunger and thirst. It’s lives and communities destroyed, and millions forced to flee.
