Tutorial: Using ngrok for Intranet Penetration — Map Your Local Machine to the Internet for WeChat Platform Debugging
Not long ago my site connected to the WeChat Official Account platform. Debugging was inconvenient — deploy the code to the server to test? That's unlikely, and could even affect the live system. So I used the intranet penetration service provided by ngrok to map my computer to the internet. Today I'll share how to use ngrok for intranet penetration and map your computer to the internet.

The window.opener Security Vulnerability and Using the rel=noopener Tag
Recently I updated my site's code to add the rel=noopener tag to friendly links and external links, so today let's discuss why we use the rel=noopener tag. In fact, this is a security vulnerability — JavaScript provides window.opener to get the Window object that created the window, and that's where the problem begins. Let's take it step by step.

Spring Cloud Microservices Beginner Tutorial (1): Microservices Introduction
My personal blog site has always stuck to one major update per year, but this time I decided not to update it, because the next update would mean adopting microservices. Using a microservices architecture for a small site would be overkill, and it takes too much time and effort to maintain. So instead of rewriting my blog from scratch, I turned it into a tutorial series.

[3] Scala Development Tutorial - Scala Basics: Variables and Constants
In "[2] Scala Development Tutorial - Scala Basics: Data Types" we discussed data types. This article will discuss variables and constants in Scala. Before learning how to declare variables and constants, let's first understand what variables and constants are: 1. Variable: A quantity whose value may change during program execution is called a variable, e.g., time, age. 2. Constant: A quantity whose value does not change during program execution is called a constant, e.g., the value 3, the character 'A'.

Get Your Own Public Exit IP Address, with Linux and Windows Support and a Programmatic API Query
You can't directly see the public IP on a computer or server—only the internal IP is visible—so a program cannot know the address of its Internet exit. I wrote another app to obtain the public IP address. It is implemented using serverless function compute, with good availability and speed, so I'm sharing it for everyone to use.

[2] Scala Development Tutorial — Scala Basics: Data Types
From the table above we can see that everything in Scala is an object — there are no primitive types like in Java. Some concepts also differ from Java: Scala includes a few notions of 'nothingness' (Null, null, Nil, Nothing, None, and Unit). Null is a trait (if you're not familiar with traits, think of it as somewhat like an abstract class in Java). There does exist an instance of null.
