When we use IDEA to DEBUG code, the console often prints something like: 'Connected to the target VM, address: 127.0.0.1:62981, transport: socket'. So even if the code doesn't run locally, as long as the JVM has debug mode on and the network can connect to the JVM via socket, the Debug protocol over Socket communication can pass debug commands and debug info.
Have you ever complained at work about other people's messy commits — no note on why or what each commit did? When contributing to open-source projects on GitHub, if your commit doesn't follow their template, your merge request won't be accepted. Messy commits not only affect others; at release time the changelog should be auto-generated, but commits not written per the rules can't be tallied automatically. So today I'll write about how to commit gracefully on Git and auto-generate the changelog. This article only focuses on the posture of committing; the commit command and other topics are not discussed for now.
This section starts from scratch: we create a new Maven multi-module project and complete a basic demo of Spring Cloud Eureka-based service registration and discovery. The demo uses the IntelliJ IDEA development environment. Create a new Maven project in IntelliJ IDEA with JDK 1.8. I prefer manual operations, so first create an empty Maven project with groupId net.renfei, artifactId cloud, and version 1.0.0.
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.
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.
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'.

Navicat Premium merges all Navicat versions into one ultimate version that can connect to MySQL, Oracle, and PostgreSQL. Navicat Premium lets users drag and drop tables and data from Oracle to MySQL, from PostgreSQL to MySQL, and from Oracle to PostgreSQL within a single client, and vice versa. In addition, batch jobs for different databases (such as printing reports in MySQL, backing up data in Oracle, and syncing data in PostgreSQL) can be scheduled and run automatically at specific times.

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.
