• SpaceX 如何降落星舰/排序
  • THOMAS GODDEN

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.

是的, JS/Py 反正以往 NASA 不用的, SpaceX 都用上了, 关键是 多快好省, 至于现代语言/系统在太空的意外错误, 通过三主机协议选举也就解决了...

• Flask 2.0中的异步
  • PATRICK KENNEDY
  • • Shared by Patrick Kennedy

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.

• 用DuckDB在 Pandas 上进行高效的SQL
  • MARK RAASVELDT AND HANNES MÜHLEISEN
  • • Shared by Alexander Monahan

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.

(是也乎:

无论 Pandas 将数据集操作折腾的多么 Pythonc, 对于广大财务人员而言, 还是 SQL 更加值得信赖. )
