What to learn about Linux application development
Linux learning is mostly based on commands, so it may feel boring or even confusing for beginners. You can complete it with just a few clicks of the mouse. Why do you have to bang so much? Here are two reasons, and you are welcome to add:
Due to resource considerations, most Linux servers do not have a graphical interface
The command line facilitates automation and writes a series of operations into scripts , can replace manual operation
And I divide its learning into several stages:
Recommended: "Linux Tutorial"
Basic use
Development and debugging
System understanding
These three stages have different requirements for knowledge accumulation, but in general there is no strict sequence divided.
Similar to windows, what did you learn when you were learning windows?
Switch the machine on or off?
Install and uninstall software? For example, install a video player or music player (why do you need to install this thing?).
How to open the installed software? For example, open a browser to surf the Internet, open an editor to write a document
How to store your own information? Move, create, delete, etc.
How to use office software
……
Do you think you haven’t bothered to learn it?
The same is true for learning Linux, which is to learn these most common uses,
How to turn on and off the computer
How to access the Internet
How to open commands Line
How to use the command line to install and uninstall software
How to edit text
How to create, move, and delete files
How to view file contents and decompress files
......
The most difficult thing at this stage is the conversion from the graphical interface to the command line.
So in the second stage, you need to learn:
How to write Linux applications
How to compile or build your program
How to run your Program
How to locate program bugs
The third stage is a long learning process, but it is all for development, including:
Understand and practice Everything is a file
ELF file, the main executable file format of Linux
The basic principles of Linux’s major mechanisms, such as process scheduling, memory management, virtual memory, file system, etc. Since you want to write Linux How can an application not understand the main mechanisms of the platform it is on?
The more difficult the problem, the more basic knowledge is needed.

To open a web.xml file, you can use the following methods: Use a text editor (such as Notepad or TextEdit) to edit commands using an integrated development environment (such as Eclipse or NetBeans) (Windows: notepad web.xml; Mac/Linux: open -a TextEdit web.xml)
Four ways to implement multithreading in C language
Apr 03, 2025 pm 03:00 PM
Multithreading in the language can greatly improve program efficiency. There are four main ways to implement multithreading in C language: Create independent processes: Create multiple independently running processes, each process has its own memory space. Pseudo-multithreading: Create multiple execution streams in a process that share the same memory space and execute alternately. Multi-threaded library: Use multi-threaded libraries such as pthreads to create and manage threads, providing rich thread operation functions. Coroutine: A lightweight multi-threaded implementation that divides tasks into small subtasks and executes them in turn.
What is the Linux best used for?
Apr 03, 2025 am 12:11 AM
Linux is best used as server management, embedded systems and desktop environments. 1) In server management, Linux is used to host websites, databases, and applications, providing stability and reliability. 2) In embedded systems, Linux is widely used in smart home and automotive electronic systems because of its flexibility and stability. 3) In the desktop environment, Linux provides rich applications and efficient performance.
How is Debian Hadoop compatibility
Apr 02, 2025 am 08:42 AM
DebianLinux is known for its stability and security and is widely used in server, development and desktop environments. While there is currently a lack of official instructions on direct compatibility with Debian and Hadoop, this article will guide you on how to deploy Hadoop on your Debian system. Debian system requirements: Before starting Hadoop configuration, please make sure that your Debian system meets the minimum operating requirements of Hadoop, which includes installing the necessary Java Runtime Environment (JRE) and Hadoop packages. Hadoop deployment steps: Download and unzip Hadoop: Download the Hadoop version you need from the official ApacheHadoop website and solve it

Is Debian Strings compatible with multiple browsers
Apr 02, 2025 am 08:30 AM
"DebianStrings" is not a standard term, and its specific meaning is still unclear. This article cannot directly comment on its browser compatibility. However, if "DebianStrings" refers to a web application running on a Debian system, its browser compatibility depends on the technical architecture of the application itself. Most modern web applications are committed to cross-browser compatibility. This relies on following web standards and using well-compatible front-end technologies (such as HTML, CSS, JavaScript) and back-end technologies (such as PHP, Python, Node.js, etc.). To ensure that the application is compatible with multiple browsers, developers often need to conduct cross-browser testing and use responsiveness
Unable to log in to mysql as root
Apr 08, 2025 pm 04:54 PM
The main reasons why you cannot log in to MySQL as root are permission problems, configuration file errors, password inconsistent, socket file problems, or firewall interception. The solution includes: check whether the bind-address parameter in the configuration file is configured correctly. Check whether the root user permissions have been modified or deleted and reset. Verify that the password is accurate, including case and special characters. Check socket file permission settings and paths. Check that the firewall blocks connections to the MySQL server.
libv are two
Apr 03, 2025 pm 08:03 PM
I developed a project called Lua-Libuv and am happy to share my experience. The original intention of the project is to explore how to use Libuv (an asynchronous I/O library written in C) to build a simple HTTP server without having to learn the C language in depth. With the help of ChatGPT, I completed the basic code of HTTP.C. When dealing with persistent connections, I successfully implemented closing the connection and freeing resources at the right time. At first I tried to create a simple server that ended the main program by closing the connection, but I had some problems. I've tried sending blocks of data using streaming, and while it works, this blocks the main thread. In the end, I decided to give up on this approach because my goal was not to learn C language in depth. Finally, I
