What is real-time operating system programming in C?
Article Introduction：C performs well in real-time operating system (RTOS) programming, providing efficient execution efficiency and precise time management. 1) C Meet the needs of RTOS through direct operation of hardware resources and efficient memory management. 2) Using object-oriented features, C can design a flexible task scheduling system. 3) C supports efficient interrupt processing, but dynamic memory allocation and exception processing must be avoided to ensure real-time. 4) Template programming and inline functions help in performance optimization. 5) In practical applications, C can be used to implement an efficient logging system.

What are some common use cases for Redis in a PHP application (e.g., caching, session handling)?
Article Introduction：Redis has four main core uses in PHP applications: 1. Cache frequently accessed data, such as query results, HTML fragments, etc., and control the update frequency through TTL; 2. Centrally store session information to solve the problem of session inconsistency in multi-server environments. The configuration method is to set session.save_handler and session.save_path in php.ini; 3. Implement current limiting and temporary counting, such as limiting the number of login attempts per hour, and using keys with expiration time for efficient counting; 4. Build a basic message queue, and implement asynchronous task processing through RPUSH and BLPOP operations, such as email sending or image processing, thereby improving system response speed and expansion

phpmaster | Uploading Files with PHP
Article Introduction：PHP file upload: build a safe and reliable upload system
Online photo album pictures, email attachments, and batch processing application data files have one thing in common: they all need to upload files to the Internet through the user's web browser. The file upload feature is an important part of many websites and web applications that are used every day. This article will show you how to add file upload support to your website using PHP.
Key Points
Adding file upload support in PHP requires creating an HTML form for users and a PHP script for processing files uploaded on the server. The element must use the POST method and set the enctype property to multipart/fo

mysql tutorial building a simple login system
Article Introduction：The core of the implementation of the login system includes four key points: database design, user input processing, password security and login status maintenance. First, the database design needs to create a user table containing fields such as id, username, email, password hashing and registration time, and ensure that the username and email address are unique; second, when verifying user information, preprocessing statements should be used to query the database to compare the hash passwords entered and stored by the user; third, the protection password must be encrypted using strong hash algorithms such as bcrypt or Argon2 to avoid plaintext storage; finally, the login status can be maintained through Session or Token (such as JWT). The former is suitable for small and medium-sized projects, and the latter is more suitable for front-end and back-end separation scenarios, and pay attention to setting security attributes to prevent attacks.

Choosing Between Golang and Python for Building Scalable Backend Systems
Article Introduction：If you are choosing a language to build a scalable backend system, Golang and Python each have their own advantages. 1. For projects with high performance and concurrency requirements, such as real-time data processing, distributed systems, and high concurrency API services, Golang is given priority because it natively supports goroutine and has strong concurrency capabilities; 2. If development efficiency is more important, or rich ecological support is required, such as rapid prototyping, data analysis combined with backend, and internal enterprise tool systems, Python is more suitable; 3. The scalability of the system depends more on the architecture design rather than the language itself. The rational adoption of microservices, sharded caches, message queues and other designs can improve scalability; 4. Learning costs and team adaptation also need to be considered, and some Go engineers have chosen Gol.

PHP Master | PhalconPHP: Yet Another PHP Framework?
Article Introduction：Phalcon PHP framework: the perfect combination of speed and efficiency
Core points:
Phalcon stands out with its extremely high speed, thanks to its unique architecture: it is a PHP module written in C that runs at the system level, reducing overhead and memory footprint.
The installation process of Phalcon is different from other frameworks. It is not simply downloading and decompressing, but installing as a PHP module. It is a full stack framework that includes functions such as ORM, request object library, and template engine.
Benchmarks show Phalcon's request processing per second is more than twice that of CodeIgniter, highlighting its speed advantage. At the same time, it also has the classic features of modern PHP MVC framework

How to manage your digital read-it-later list—before it’s too late
Article Introduction：Most of us have some sort of system to save online articles we want to read…eventually. Maybe you're favorite tweets, use a dedicated app like Instapaper, add links to bookmark folders, or open millions of tabs in your web browser.
There is only one problem with this habit: you add stories to the list faster than you check, and you add your summary every week. Ultimately, reading the list later can be as clogged as an email inbox.
It's time to finish the story pile you saved — or at least reduce it to a manageable size. Here are some strategies to help you complete your own assigned reading tasks.
Integrate your list
You need to know all within before you start processing your later reading heap

Is golang frontend or backend
Article Introduction：Golang is mainly used for back-end development, but it can also play an indirect role in the front-end field. Its design goals focus on high-performance, concurrent processing and system-level programming, and are suitable for building back-end applications such as API servers, microservices, distributed systems, database operations and CLI tools. Although Golang is not the mainstream language for web front-end, it can be compiled into JavaScript through GopherJS, run on WebAssembly through TinyGo, or generate HTML pages with a template engine to participate in front-end development. However, modern front-end development still needs to rely on JavaScript/TypeScript and its ecosystem. Therefore, Golang is more suitable for the technology stack selection with high-performance backend as the core.
