.NET Core Quick Start Tutorial 1. The beginning: Talking about .NET Core
May 07, 2025 pm 04:54 PM
1. The Origin of .NETCore When talking about .NETCore, we must not mention its predecessor .NET. Java was in the limelight at that time, and Microsoft also favored Java. The Java virtual machine on the Windows platform was developed by Microsoft based on JVM standards. It is said to be the best performance Java virtual machine at that time. However, Microsoft has its own little abacus, trying to bundle Java with the Windows platform and add some Windows-specific features. Sun's dissatisfaction with this led to a breakdown of the relationship between the two parties, and Microsoft then launched .NET. .NET has borrowed many features of Java since its inception and gradually surpassed Java in language features and form development. Java in version 1.6

The difference between programming in Java and other languages ??Analysis of the advantages of cross-platform features of Java
May 20, 2025 pm 08:21 PM
The main difference between Java and other programming languages ??is its cross-platform feature of "writing at once, running everywhere". 1. The syntax of Java is close to C, but it removes pointer operations that are prone to errors, making it suitable for large enterprise applications. 2. Compared with Python, Java has more advantages in performance and large-scale data processing. The cross-platform advantage of Java stems from the Java virtual machine (JVM), which can run the same bytecode on different platforms, simplifying development and deployment, but be careful to avoid using platform-specific APIs to maintain cross-platformity.

After installing Nginx, the configuration file path and initial settings
May 16, 2025 pm 10:54 PM
Understanding Nginx's configuration file path and initial settings is very important because it is the first step in optimizing and managing a web server. 1) The configuration file path is usually /etc/nginx/nginx.conf. The syntax can be found and tested using the nginx-t command. 2) The initial settings include global settings (such as user, worker_processes) and HTTP settings (such as include, log_format). These settings allow customization and extension according to requirements. Incorrect configuration may lead to performance issues and security vulnerabilities.
