• The author's Python code was slow and they made it faster.
• They worked on SPy and its integration with Pyodide.
• They discussed the evolution of Python and the Web platform.
• They introduced SPy and its features.
• They converted a Genuary entry to SPy and improved performance.
• They added bitwise operator support to the SPy compiler.
• The author discussed the potential of skipping CPython in the Web browser.

Key details:

• The author gave a keynote in 2019 called "Python 2020+" and argued for the need for new Python-like languages on the Web.
• Pyodide is a port of CPython running on WebAssembly, but has performance limitations compared to JavaScript.
• SPy is a language designed to be friendly to Python users and can be fully compiled to native binaries or WebAssembly.
• The SPy version of a Genuary entry was 100X faster than the original Python version due to pre-computation.
• The SPy project is in early stages and the author had to add bitwise operator support and an array implementation.
• The author discussed the potential of skipping CPython in the Web browser and the need for more resources for the SPy project.
