Eternal sunshine of the spotless development environment
summary
Claims that an open Dev Containers spec encodes a full editor + runtime workspace and that it reduces onboarding friction are demonstrated with concrete tooling: Docker / miniconda Dockerfile, VS Code settings and extensions, GitHub Codespaces (free 60 hours/month), PyCharm and DevPod support, features for tooling like Azure CLI. A numpy Dev Container used for monthly newcomer sprints proves the workflow at scale, prebuilds make launches fast, and a local Docker crash during demo is recovered by launching a prebuilt Codespaces session from a conda-based Dockerfile.
