        GitHub Workflow
        ---------------
        
        
        Summmary
        --------
        
        Is Python an interpreted or compiled language? Trick question. It’s actually
        both. With tools like Cython, we can take the compilation step further and
        remove the interpreter loop almost entirely. Cython produces binaries much like
        C++, Go, and Rust do. Now with GitHub Actions the cross-platform build and
        release process can be automated for free for Open Source projects. This is an
        enormous opportunity to make the Python ecosystem 20-50% faster with a single
        pull request. The lightning talk will walk through a GitHub workflow that
        publishes Cython-optimized wheels to PyPI. Discover how Cython can turbo-charge
        your Python code and GitHub Actions can simplify your cross-platform release
        process for free.
