Unboxing Devcontainers and Docker Devcontainers give you the experience of local development with the portability of Docker! You have the freedom to run your dev environment anywhere – mac, Linux, the Cloud, or even Windows! But Docker, Docker Compose, and Devcontainers are confusing. Let’s talk about what they are, how they’re different, and how to configure them.

When you’re upgrading Ruby, it’s hard to remember to update your docker image too. This GitHub Action checks if they’re in sync and warns you if they arent!

SF Ruby Conference 2025 was a three-day Ruby conference that took place in San Francisco, California on November 19-21, 2025.

In this Dead Code podcast episode, Jared Norman interviews Chael Wright-Munn (ChaelCodes) about the benefits of working openly through activities like live streaming and contributing to open-source projects. Chael emphasizes how creating a “library of examples” through public coding can enhance a developer’s skills, build their professional network, and preserve their achievements beyond their current job. She offers practical advice on starting a stream, such as using OBS software, focusing on community building, and engaging in structured projects like Hacktoberfest. The discussion highlights the value of maintaining a visible presence in the tech community, whether through streaming, open-source contributions, or other public-facing efforts, as a way to retain knowledge and showcase work, even across job changes.
