Edit the SSH daemon config:

import i18n from 'i18next';
import { initReactI18next } from 'react-i18next';
import LanguageDetector from 'i18next-browser-languagedetector';

import en from './locales/en.json';
import fr from './locales/fr.json';

i18n
  .use(LanguageDetector)
  .use(initReactI18next)
  .init({
    resources: { en: { translation: en }, fr: { translation: fr } },
    fallbackLng: 'en',
    interpolation: {
      escapeValue: false,
    },
  });

export default i18n;

Sample en.json:

new Intl.NumberFormat('en-US', {
  style: 'currency',
  currency: 'USD'
}).format(4999.99);

// Output: $4,999.99

Make this dynamic in React:

This saves the user's preferred language so it's remembered on the next visit.

Implementing i18n is no longer optional — it's essential in 2025 as user bases go global and inclusive design becomes the standard.

In 2025, micro-frontends are not just a buzzword — they are a proven way to scale modern frontend architectures. With Webpack Module Federation, teams can deliver independently developed features without sacrificing user experience or performance.

By following this guide, you’ve created a flexible, scalable frontend system that combines React and Vue in real time — powered by the magic of Webpack 5.

Zustand isn't just for simple state management; it also offers advanced features that cater to more complex scenarios:

Zustand supports middleware for logging, persisting state, and more. For example, integrating with Redux DevTools:

   const ThemeContext = React.createContext();
   const UserContext = React.createContext();

   const value = useMemo(() => ({ user, setUser }), [user]);

Then you'll need to restart MySQL:

sudo systemctl stop mysql

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

   sudo a2ensite your_domain.conf
   sudo a2enmod rewrite
   sudo systemctl restart apache2

Composer is essential for managing PHP dependencies:

Install the recommended version:

sudo apt install nvidia-driver-550 nvidia-prime

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

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

    ~ScopedPointer() {
        delete ptr;
    }

    T& operator*() const { return *ptr; }
    T* operator->() const { return ptr; }
    T* get() const { return ptr; }

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

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

For arrays:

Shallow a(10);
Shallow b = a;  // default copy constructor

This causes both a.data and b.data to point to the same memory. When both destructors run, delete is called twice on the same pointer — undefined behavior!

Even though CSRF isn’t about spam exactly, CSRF tokens prevent cross-site attacks, which bots might exploit.

Most frameworks like Laravel, Django, or Express have CSRF protection built-in—use it.

You’re no longer blindly relying on a package—you understand and control the system.

• Sensors and Actuators: Learn how to interface with various sensors (e.g., temperature, distance) and control motors or servos.
• Serial Communication: Understand how to send and receive data between the Arduino and your computer.
• Advanced Projects: Dive into projects that combine multiple components for more interactive applications.

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:

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);
    }
  }
}

Tauri packages your Svelte frontend along with the Rust backend into a lightweight, platform-specific binary.

Tauri provides many built-in APIs to interact with the system (e.g., file system, notifications, dialogs). To call a Tauri API from Svelte, use the Tauri JavaScript API. For example, to display a notification:

Example DSL Code:

(3 + 4) * (5 - 2) / 2
