  • Pyston is back

    Pyston, the Python Runtime with Just-In-Time (JiT) compiler, appears to be back. After the project lost support from Dropbox, development seemed to have ceased. A new team just released version 2, that is compatible with Python 3.8. It promises 20% performance gain over cPython, the default implementation. Here is the announcement: The Pyston Blog

  • The Dropbox journey to static type checking with Python

    Type Annotation is a feature that allows Python to maintain it’s dynamic typing and enable option static typing in the same code base. With the arrival of Python 3.5, the language implemented PEP 484, that describes a syntax to annotate code with type hints. Dropbox took a journey to leverage this option on 4 million lines of code for better quality. Here are their experiences.

    Dropbox is a big user of Python. It’s our most widely used language both for backend services and the desktop client app (we are also heavy users of Go, TypeScript, and Rust).
