In the context of logging, the word "structured" typically refers to the way log records are represented in a machine-readable format, such as JSON or XML. In this article, we focus on another aspect of logging structure: the message content. Computing today offers several automated ways of collecting, delivering, and processing log records from different types of systems. But modern...

This paper presents our experience with Treble, a two-year initiative to build the modular base in Android, a Java-based mobile platform running on the Linux kernel. Our TREBLE architecture splits the hardware independent core framework written in Java from the hardware dependent vendor implementations (e.g., user space device drivers, vendor native libraries, and kernel written in C/C++)....

The Accelerate State of DevOps Report represents six years of work and data from over 31,000 professionals worldwide. It is the largest and longest-running research of its kind, providing an independent view into the practices and capabilities that drive high performance. The results enable us to understand the practices that lead the powerful business outcomes that result from excellence in...

Code coverage is a measure of the degree to which a test suite exercises a software system. Although coverage is well established in software engineering research, deployment in industry is often inhibited by the perceived usefulness and the computational costs of analyzing coverage at scale. At Google, coverage information is computed for one billion lines of code daily, for seven programming...
