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

Integrating Postman applications on CentOS can be achieved through a variety of methods. The following are the detailed steps and suggestions: Install Postman by downloading the installation package to download Postman's Linux version installation package: Visit Postman's official website and select the version suitable for Linux to download. Unzip the installation package: Use the following command to unzip the installation package to the specified directory, for example /opt: sudotar-xzfpostman-linux-x64-xx.xx.xx.tar.gz-C/opt Please note that "postman-linux-x64-xx.xx.xx.tar.gz" is replaced by the file name you actually downloaded. Create symbols

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.

Setting the location of the interpreter in PyCharm can be achieved through the following steps: 1. Open PyCharm, click the "File" menu, and select "Settings" or "Preferences". 2. Find and click "Project:[Your Project Name]" and select "PythonInterpreter". 3. Click "AddInterpreter", select "SystemInterpreter", browse to the Python installation directory, select the Python executable file, and click "OK". When setting up the interpreter, you need to pay attention to path correctness, version compatibility and the use of the virtual environment to ensure the smooth operation of the project.

The steps to manually install the plug-in package in VSCode are: 1. Download the .vsix file of the plug-in; 2. Open VSCode and press Ctrl Shift P (Windows/Linux) or Cmd Shift P (Mac) to call up the command panel; 3. Enter and select Extensions:InstallfromVSIX..., then select .vsix file and install. Manually installing plug-ins provides a flexible way to install, especially when the network is restricted or the plug-in market is unavailable, but attention needs to be paid to file security and possible dependencies.

[Common Directory Description] Directory/bin stores binary executable files (ls, cat, mkdir, etc.), and common commands are generally here. /etc stores system management and configuration files/home stores all user files. The root directory of the user's home directory is the basis of the user's home directory. For example, the home directory of the user user is /home/user. You can use ~user to represent /usr to store system applications. The more important directory /usr/local Local system administrator software installation directory (install system-level applications). This is the largest directory, and almost all the applications and files to be used are in this directory. /usr/x11r6?Directory for storing x?window/usr/bin?Many

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.

The installation and configuration of MySQL can be completed through the following steps: 1. Download the installation package suitable for the operating system from the official website. 2. Run the installer, select the "Developer Default" option and set the root user password. 3. After installation, configure environment variables to ensure that the bin directory of MySQL is in PATH. 4. When creating a user, follow the principle of minimum permissions and set a strong password. 5. Adjust the innodb_buffer_pool_size and max_connections parameters when optimizing performance. 6. Back up the database regularly and optimize query statements to improve performance.
