2. Solutions to system-level problems

In actual production, it is generally believed that as long as the CPU does not exceed 90%, there will be no problems. In fact, the following special situation cannot be ruled out:

How does process management differ between Linux and Windows?How does process management differ between Linux and Windows?May 04, 2025 am 12:04 AM

The main difference between Linux and Windows in process management lies in the implementation and concept of tools and APIs. Linux is known for its flexibility and power, relying on kernel and command line tools; while Windows is known for its user-friendliness and integration, mainly managing processes through graphical interfaces and system services.

What are the differences in user account management between Linux and Windows?What are the differences in user account management between Linux and Windows?May 02, 2025 am 12:02 AM

The main difference between Linux and Windows in user account management is the permission model and management tools. Linux uses Unix-based permissions models and command-line tools (such as useradd, usermod, userdel), while Windows uses its own security model and graphical user interface (GUI) management tools.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
