Explaining JSON Web Token (JWT) To a 10 Year Old Kid

This digest from ByteByteGo's system design refresher covers several topics, with a feature on JWTs, Docker, server types and Linux learning paths. The JWT explanation says a token has three parts: a header describing the box type and how it is secured, a payload carrying the message such as a name or age, and a signature made with a secret code that prevents tampering without the sender's knowledge. The Docker section, by guest author Rohit Sehgal, describes three components: the Docker client, the Docker host daemon, and registries such as Docker Hub. It lists six steps for "docker run", from pulling the image to starting the container. The newsletter also promotes its own Substack, which it says has 500,000 readers.
