وتستخدم أقل، حيث يتم تعيين التبعية مباشرة في خاصية داخل الكائن.

تستخدم العديد من الأُطر الحديثة—مثل Laravel، Symfony، Spring، Angular—حاويات (Containers) تقوم بإدارة وإنشاء التبعيات تلقائياً. يسمح هذا للمطور بالتركيز على منطق العمل بدلاً من إدارة إنشاء الكائنات يدوياً.

This makes the server send a keep-alive packet every 60 seconds, allowing up to 3 missed replies before disconnecting.

Restart SSH:

Create routes.js:

import Home from './pages/Home';
import About from './pages/About';

export const routes = (t) => [
  {
    path: `/${t('routes.home')}`,
    element: <Home />,
  },
  {
    path: `/${t('routes.about')}`,
    element: <About />,
  },
];

Or customize promotions, payment options, and availability by locale.

In 2025, users expect more than just language translation — they want your app to feel native to their region, culture, and behavior.

/locales
  /en
    home.json
    dashboard.json
  /fr
    home.json
    dashboard.json

Then load them like:

Each micro-frontend should be versioned and deployed separately.

Use shared in Module Federation to prevent loading duplicate libraries (like react, vue, etc.).

Key Features:

• Simplicity: Create stores using a straightforward API without the need for reducers or action types.
• Performance: Optimized for performance with selective rendering and minimal re-renders.
• Flexibility: Supports custom hooks, middleware, and integration with other libraries.
• No Providers: Unlike Redux, Zustand doesn't require wrapping your app with context providers.

React re-renders components when there's a change in state or props. While this ensures the UI stays in sync with data, it can also lead to redundant renders, especially in large component trees. Identifying and mitigating these unnecessary re-renders is key to optimizing performance.([GeeksforGeeks][2])

React.memo is a higher-order component that prevents functional components from re-rendering if their props haven't changed. It performs a shallow comparison of props and reuses the previous render result when possible.([JavaScript in Plain English][3])

Check that the validation system is gone:

datadir = /var/lib/mysql

Change it to:

• When prompted to choose a web server, select apache2.
• Choose Yes when asked to configure the database for phpMyAdmin with dbconfig-common.
• Set a password for the phpMyAdmin application.

Enable the mbstring PHP extension and restart Apache:

If prime-run doesn't exist, create it:

sudo nano /usr/bin/prime-run

In this tutorial, you'll learn:

• How memory leaks happen.
• How to structure your code to avoid them.
• A design pattern to manage dynamic memory safely (RAII without smart pointers).
• A reusable ScopedPointer class to emulate unique_ptr in old C++.

A shallow copy copies the values of member variables as-is. If your class has a pointer member, both the original and copy point to the same memory.

class Shallow {
public:
    int* data;

    Shallow(int val) {
        data = new int(val);
    }

    ~Shallow() {
        delete data;
    }
};

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

Why it works: Bots usually fill every field, including hidden ones. Real users never see it.

{
  "error": "Too many requests. Try later."
}

Instead of IP address, use API keys for user-specific limits:

Table 1: A comparison of popular Arduino boards.

Choose your board based on the complexity and size of your project.

let video;
let detector;
let detections = [];

function setup() {
  // Create the canvas to match the video dimensions
  createCanvas(640, 480);
  // Capture video from the webcam
  video = createCapture(VIDEO);
  video.size(640, 480);
  video.hide();

  // Load the pre-trained COCO-SSD model
  cocoSsd.load().then(model => {
    detector = model;
    console.log("Model Loaded!");
    // Begin detecting objects every frame
    detectObjects();
  });
}

function detectObjects() {
  detector.detect(video.elt).then(results => {
    detections = results;
    // Continue detection in a loop
    detectObjects();
  });
}

function draw() {
  // Draw the video
  image(video, 0, 0);

  // Draw detection boxes and labels if available
  if (detections) {
    for (let i = 0; i < detections.length; i++) {
      let object = detections[i];
      stroke(0, 255, 0);
      strokeWeight(2);
      noFill();
      rect(object.bbox[0], object.bbox[1], object.bbox[2], object.bbox[3]);
      noStroke();
      fill(0, 255, 0);
      textSize(16);
      text(object.class, object.bbox[0] + 4, object.bbox[1] + 16);
    }
  }
}

• Setup: The setup function initializes the canvas and video capture. The video is hidden by p5.js’s default element so that we can draw it onto the canvas manually.
• Model Loading: We load the COCO-SSD model asynchronously. Once the model is ready, we start continuous object detection by calling detectObjects().
• Detection Loop: The detectObjects function uses the loaded model to analyze the current video frame and stores the detection results. It recursively calls itself so that new frames are analyzed continuously.
• Drawing: In the draw loop, the video feed is displayed and for each detected object, a rectangle and label are drawn. The bounding box coordinates and object class are provided by the model.

We’ll start by creating a new Svelte project. You can use a template via degit:

• Numeric literals (e.g., 42, 3.14)
• Basic arithmetic operators: +, -, *, /
• Parentheses for grouping expressions

Later, you can extend it to include variables, functions, or even control flow constructs.
