This document appears to be a transcript from a presentation by Yegor Bugayenko given at DevOpsConf 2018 in Moscow, Russia. The presentation discusses focusing on quality over quantity in software projects and implementing fear-driven development practices like rigorous testing and code reviews to motivate high-quality work. It also promotes the concepts of making small, isolated changes and experimentation to improve quality.

“Each stage of a build pipeline is
looking for reasons to reject the build.
Tests failed? Reject it. Lint complains?
Reject it. Build fails integration tests in
staging? Reject it. Finished archive
smells funny? Reject it.”
