عندما تعتمد الكائنات على إنشاء التبعيات داخلياً، فإن النظام يصبح مترابطاً بشكل كبير. حقن التبعيات يفصل عملية الإنشاء عن الاستخدام، مما يقلل الترابط ويجعل البنية أكثر تنظيماً.

يسهل حقن التبعيات استبدال العناصر الحقيقية بمحاكاة (Mocks) أثناء الاختبارات، مما يقلل التعقيد ويزيد دقة نتائج الاختبار.

This ensures your SSH client pings the server regularly.

Start with a React project (you can use CRA or Vite):

npx create-react-app react-i18n-routing
cd react-i18n-routing

new Intl.DateTimeFormat('fr-FR').format(new Date());
// Output: 04/05/2025 (French format)

React example:

import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';
import './i18n'; //  import i18n config

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(<App />);

Use the useTranslation hook:

Create src/components/Analytics.vue:

<template>
  <div class="analytics">
    <h2>Real-Time Analytics</h2>
    <p>This component is loaded remotely via Module Federation.</p>
  </div>
</template>

<script>
export default {
  name: 'Analytics',
};
</script>

Zustand allows you to select specific parts of the state to prevent unnecessary re-renders:

const count = useStore((state) => state.count);

Steps:

Regular profiling helps in maintaining optimal performance as the application evolves.([Content That Scales][5])

INSTALL COMPONENT 'file://component_validate_password';

Then you'll need to restart MySQL:

Choose your new location, for example /mnt/data/mysql, and move the current data:

sudo mv /var/lib/mysql /mnt/data/mysql

sudo phpenmod mbstring
sudo systemctl restart apache2

You can now access phpMyAdmin at http://localhost/phpmyadmin.

Open a terminal and run:

lspci -k | grep -EA3 'VGA|3D|Display'

For arrays:

template <typename T>
class ScopedArray {
private:
    T* ptr;

public:
    explicit ScopedArray(T* p = nullptr) : ptr(p) {}

    ~ScopedArray() {
        delete[] ptr;
    }

    T& operator[](int index) const { return ptr[index]; }
    T* get() const { return ptr; }

    void reset(T* p = nullptr) {
        if (ptr != p) {
            delete[] ptr;
            ptr = p;
        }
    }

    // Prevent copy
    ScopedArray(const ScopedArray&) = delete;
    ScopedArray& operator=(const ScopedArray&) = delete;
};

When your class uses raw pointers:

• Avoid shallow copies.
• Always implement deep copy logic.
• Follow the Rule of Three (or Rule of Five).
• Prefer std::string, std::vector, or smart pointers in modern C++.

<input type="text" name="phone_number" style="display:none" autocomplete="off">

if (!empty($_POST['phone_number'])) {
  die("Bot detected");
}

Protect your API from abuse and learn how rate limiting works under the hood.

When developing web apps or APIs, it’s critical to prevent users from overwhelming your server. That’s where rate limiting comes in. In this guide, we’ll build a custom rate limiter in Node.js using Redis—no libraries, no magic, just code you control and understand.

• Arduino board (e.g., Arduino Uno)
• Breadboard
• LED
• 220Ω resistor
• Jumper wires

• Connect the longer leg (anode) of the LED to digital pin 13.
• Connect the shorter leg (cathode) to one end of the 220Ω resistor.

This guide will walk you through setting up your development environment, loading a pre-trained model, capturing video input, and overlaying detection results on the video feed.

Before you begin, make sure you have the following installed and set up:

Open the src-tauri/tauri.conf.json file to adjust settings like the application window, bundle identifiers, and security policies. For example, you might configure the window title and size:

{
  "package": {
    "productName": "TauriSvelteApp",
    "version": "0.1.0"
  },
  "tauri": {
    "windows": [
      {
        "title": "My Tauri App",
        "width": 800,
        "height": 600,
        "resizable": true
      }
    ],
    "security": {
      "csp": "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'"
    }
  }
}
