This happens even with minimal code that does not use json, re, or any APIs—looks like the interpreter receives a Message object where a plain string is expected (possibly before user code runs).

Abstract: With the fast development in aeronautical technology, aircraft is evolving toward a wider speed ranging from subsonic, transonic, and supersonic to hypersonic speeds. The variable-sweep-wing ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

It’s often the case that as we are writing code, we don’t have all the information we need for our program to produce the desired result. For example, imagine you were asked to write a calculator ...

Python 3.11 introduced the Specializing Adaptive Interpreter. When the interpreter detects that some operations predictably involve the same types, those operations are “specialized.” The generic ...

Abstract: A dual-port antenna has been designed, which is applied to the ultra-wideband system, together with consideration of multiple input multiple output function. Each antenna element was ...
