How SpaceX Lands Starship (Sort Of)
While waiting for SN15 to launch, Thomas Goddard set out to pull together a 2-dimensional simulation of the Starship landing. Tying together knowledge of trajectory optimization, Thomas modeled the landing in Python with the CasADI library and used Matplotlib to generate an animation which, when played side-by-side with the footage of the landing, results in remarkable similarity to the actual landing dynamics.

Async in Flask 2.0
This article looks at Flask 2.0’s new async functionality and how to leverage it in your Flask projects. You’ll learn how Flask processes requests asynchronously using a traditional WSGI server, instead of the ASGI server used by many other async web frameworks. You’ll also learn how to simulate Flask 2.0 async in Flask 1.X applications.

Efficient SQL on Pandas with DuckDB
pandas is an indispensable tool for Python data analysis. It’s also a standard for data transfer between elements of the Python data ecosystem. But sometimes you need some good ol’ SQL in your data workflow. With DuckDB, you can perform SQL queries directly against pandas data frames. DuckDB is faster than pandas in some cases and can even handle larger-than-memory data.
