This document describes the high level system design of an MPC-based approach to the Private Reach and Frequency Estimation. The MPC protocol was previously described in Privacy Preserving Secure Cardinality and Frequency Estimation [1], and although several modifications are forthcoming, they do not impact the overall system design.

We present a framework for automatically testing functional correctness of back-end servers. We created a pre-production environment where traffic between servers can be reconfigured dynamically. Production requests are sampled and replayed in our framework so that we can cover many corner cases of the system without having the developer manually write test cases. We also describe how to handle...

Understanding developers’ day-to-day behavior can help answer important research questions, but capturing that behavior at scale can be challenging, particularly when developers use many tools in concert to accomplish their tasks. In this paper, we describe our experience creating a system that integrates log data from dozens of development tools at Google, including tools that developers use...

In continuous integration development environments, software engineers frequently integrate new or changed code with the mainline codebase. This can reduce the amount of code rework that is needed as systems evolve and speed up development time. While continuous integration processes traditionally require that extensive testing be performed following the actual submission of code to the...
