1. Interface-Oriented Programming 1.1 Characteristics Interface-oriented programming emphasizes interaction between modules through interfaces. First, the caller specifies a set of method signatures; then, the callee implements that set of methods. What sets interface programming apart from other programming styles is that it focuses on methods, not attributes. In many programming scenarios, methods are defined around attributes.

1. The Concurrency Model in Go 1.1 The Communication Model: CSP CSP stands for Communicating Sequential Process, a model for concurrent communication. A Process can use many Channels, and a Channel does not care who is using it — it is only responsible for sending and receiving data. In the Go community there is a very famous maxim: do not communicate by sharing memory; instead, share memory by communicating.

1. What a Programming Paradigm Is A programming paradigm is a class of typical programming conventions. On one hand, it provides engineers with a way to model entities, linking the physical world to code; on the other hand, it provides engineers with a way of thinking about code and programs.

When Base64-decoding a JWT, I found that the JSON data was incomplete. This article mainly introduces the relevant knowledge and solves this problem. 1. Introduction to JWT JWT passes authentication by setting Authorization: Bearer <token> in the Header. A JWT Token is a Base64-encoded string joined by dots, something like

With the Operator approach, Kubernetes functionality can be extended in a friendly way. Operator = CRD + Controller. First you generate the CRD from a yaml definition, then the Controller continuously watches the data in etcd and performs the corresponding actions. There is a lot of tedious and repetitive work involved in developing an Operator.
