بهذه الطريقة، يصبح كل كائن أقل اعتماداً على التفاصيل الداخلية، وأكثر مرونة وقابلاً للاختبار.

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.

If your SSH session closes after a minute of inactivity, it’s usually caused by idle timeouts. You can fix this with keep-alive settings on both the server and client.

Edit the SSH daemon config:

Create pages/Home.js:

import { useTranslation } from 'react-i18next';

export default function Home() {
  const { t } = useTranslation();
  return (
    <div>
      <h1>{t('title')}</h1>
    </div>
  );
}

• GDPR requires local-language privacy policies
• China's Cybersecurity Law needs local hosting + Mandarin support
• Saudi localization laws mandate Arabic for all government services

Your React app must support legal localization where applicable.

npm install i18next react-i18next i18next-browser-languagedetector

Create a new file: src/i18n.js

npm install -D webpack webpack-cli webpack-dev-server html-webpack-plugin

Create a webpack.config.js:

import create from 'zustand';
import { persist } from 'zustand/middleware';

const useStore = create(persist(
  (set) => ({
    count: 0,
    increase: () => set((state) => ({ count: state.count + 1 })),
  }),
  {
    name: 'counter-storage',
  }
));

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

   const increment = useCallback(() => setCount(c => c + 1), []);

Implementing these practices ensures that only components dependent on specific context values re-render when those values change.([Medium][7])

If you want to bring back strong password policies:

INSTALL COMPONENT 'file://component_validate_password';

Ensure MySQL can access the new directory:

sudo chown -R mysql:mysql /mnt/data/mysql

php -v

Install the MySQL server package:

If your NVIDIA GPU isn’t detected properly on Ubuntu, or nvidia-smi shows an error like "couldn't communicate with the NVIDIA driver", this guide will walk you through how to fix that.

This was tested and confirmed working on a Dell Vostro 3521 with an NVIDIA GeForce MX350 GPU.

C++ developers often face memory management headaches, especially when working on legacy systems that don’t use C++11 or newer. Smart pointers like std::unique_ptr and std::shared_ptr are powerful, but what if you’re stuck with raw pointers?

In this tutorial, you'll learn:

class String {
private:
    char* buffer;

public:
    String(const char* str) {
        buffer = new char[strlen(str) + 1];
        strcpy(buffer, str);
    }

    // Copy constructor
    String(const String& other) {
        buffer = new char[strlen(other.buffer) + 1];
        strcpy(buffer, other.buffer);
    }

    // Assignment operator
    String& operator=(const String& other) {
        if (this != &other) {
            delete[] buffer;
            buffer = new char[strlen(other.buffer) + 1];
            strcpy(buffer, other.buffer);
        }
        return *this;
    }

    ~String() {
        delete[] buffer;
    }

    void print() const {
        std::cout << buffer << std::endl;
    }
};

String a("Hello");
String b = a;       // deep copy
String c("World");
c = a;              // deep assignment

A honeypot is a hidden form field that users don’t see, but bots do. If the field is filled, you know it’s a bot.

Table 2: Digital vs. Analog signals in Arduino projects.

One of the simplest and most popular starter projects is blinking an LED. Follow these steps:

This HTML file loads p5.js, TensorFlow.js, and the COCO-SSD model library. We also reference our custom script file (sketch.js), which will contain our application logic.

Create a new file called sketch.js in your project folder. We’ll use p5.js to access the webcam and display the video on a canvas:

Tauri leverages web technologies to build native desktop applications while offloading critical operations to Rust. Paired with Svelte—a fast, compile-time JavaScript framework—you can create modern apps that are both visually appealing and highly performant. This tutorial will walk you through setting up your development environment, creating a Svelte project, integrating Tauri, and building your first desktop app.
