The State of the Octoverse 2019

GitHub's annual Octoverse report highlights the dynamic growth and interconnectedness of the global software development community, now comprising over 40 million developers, the majority of whom are outside the United States. The report reveals significant contributions to open-source projects from developers worldwide, including notable participation from organizations such as 35 of the Global Fortune 50. Over 44 million repositories were created in the past year, showcasing a trend towards increased reliance on shared open-source infrastructure, with each repository depending on an average of more than 200 packages. Security also emerged as a collaborative effort, with the GitHub community remediating over 7.6 million vulnerability alerts through a combined effort of maintainers, developers, and automated tools like Dependabot. Noteworthy trends include Python surpassing Java as the second-most popular language, the rapid growth of Dart and Rust, and the significant rise in the use of Jupyter Notebooks. These developments underscore the collaborative nature of modern software development, driven by a diverse and expansive global community.
