Recent security issues with GitHub Actions involved the modification of the tj-actions/changed-files action, which leaked secrets. To mitigate such vulnerabilities, the author recommends pinning versions to explicit commit hashes and introduces a tool called "just an installer" (jas) that verifies downloads using SHA-256 hashes, enhancing the reliability of binary installations in GitHub Actions workflows.

The article details the author's journey to solve the long installation times of the rdkafka gem in Ruby, which is critical for Apache Kafka integration. By creating precompiled binaries and implementing a robust build and security system, installation times were significantly reduced from over 60 seconds to under 5 seconds, enhancing overall developer experience and reducing resource waste.
