There are three main ways to install software on Linux: 1. Use a package manager, such as apt, dnf or pacman, and then execute the install command after updating the source, such as sudoaptininstallcurl; 2. For .deb or .rpm files, use dpkg or rpm commands to install, and repair dependencies when needed; 3. Use snap or flatpak to install applications across platforms, such as sudosnapinstall software name, which is suitable for users who are pursuing version updates. It is recommended to use the system's own package manager for better compatibility and performance.

Linux is suitable for old hardware, has high security and is customizable, but has weak software compatibility; Windows software is rich and easy to use, but has high resource utilization. 1. In terms of performance, Linux is lightweight and efficient, suitable for old devices; Windows has high hardware requirements. 2. In terms of software, Windows has wider compatibility, especially professional tools and games; Linux needs to use tools to run some software. 3. In terms of security, Linux permission management is stricter and updates are convenient; although Windows is protected, it is still vulnerable to attacks. 4. In terms of difficulty of use, the Linux learning curve is steep; Windows operation is intuitive. Choose according to requirements: choose Linux with performance and security, and choose Windows with compatibility and ease of use.

EloquentORM is Laravel's built-in object relational mapping system. It operates the database through PHP syntax instead of native SQL, making the code more concise and easy to maintain; 1. Each data table corresponds to a model class, and each record exists as a model instance; 2. Adopt active record mode, and the model instance can be saved or updated by itself; 3. Support batch assignment, and the $fillable attribute needs to be defined in the model to ensure security; 4. Provide strong relationship support, such as one-to-one, one-to-many, many-to-many, etc., and you can access the associated data through method calls; 5. Integrated query constructor, where, orderBy and other methods can be called chained to build queries; 6. Support accessors and modifiers, which can format the number when obtaining or setting attributes.
