Raspberry Pi OS vs Ubuntu: Which One is Best for Desktop Usage?

Most of you should already know Raspberry Pi OS as it’s the default operating system for any beginner on Raspberry Pi, but other options are available, and Ubuntu is the most popular among them.

Especially for PC users, if you are used to it on your standard computer, you might be tented to switch to it on Raspberry Pi too. Is it worth it? We’ll take a look at this in this article, I’ve tested both and can share my impressions with you.

Anyway, I compare everything in this video, and you’ll understand how I evaluated these criteria and pick this score for each of them.

Procedure To Become An Air Hostess/Cabin Crew

Minimum educational required – 10+2 passed in any stream from a recognized board.

The age limit is 18 to 25 years. It may differ from one airline to another!

 

Physical and Medical standards –

  • Females must be 157 cm in height and males must be 170 cm in height (for males). This parameter may vary from one airline toward the next.
  • The candidate's body weight should be proportional to his or her height.
  • Candidates with blemish-free skin will have an advantage.
  • Physical fitness is required of the candidate.
  • Eyesight requirements: a minimum of 6/9 vision is required. Many airlines allow applicants to fix their vision to 20/20!
  • There should be no history of mental disease in the candidate's past.
  • The candidate should not have a significant cardiovascular condition.

You can become an air hostess if you meet certain criteria, such as a minimum educational level, an age limit, language ability, and physical characteristics.

As can be seen from the preceding information, a 10+2 pass is the minimal educational need for becoming an air hostess in India. So, if you have a 10+2 certificate from a recognized board, you are qualified to apply for an interview for air hostess positions!

You can still apply for this job if you have a higher qualification (such as a Bachelor's or Master's Degree).

So That I may recommend, joining Special Personality development courses, a learning gallery that offers aviation industry courses by AEROFLY INTERNATIONAL AVIATION ACADEMY in CHANDIGARH. They provide extra sessions included in the course and conduct the entire course in 6 months covering all topics at an affordable pricing structure. They pay particular attention to each and every aspirant and prepare them according to airline criteria. So be a part of it and give your aspirations So be a part of it and give your aspirations wings.

Tools and Images to Build a Raspberry Pi n8n server

Introduction

The purpose of this project is to create a Raspberry Pi image preconfigured with n8n so that it runs out of the box.

What is n8n?

n8n is a no-code/low code environment used to connect and automate different systems and services. It is programmed using a series of connected nodes that receive, transform, and then transmit date from and to other nodes. Each node represents a service or system allowing these different entities to interact. All of this is done using a WebUI.

Why n8n-pi?

Whevever a new technology is released, two common barriers often prevent potential users from trying out the technology:

  1. System costs
  2. Installation & configuration challenges

The n8n-pi project eliminates these two roadblocks by preconfiguring a working system that runs on easily available, low cost hardware. For as little as $40 and a few minutes, they can have a full n8n system up and running.

Thanks!

This project would not be possible if it was not for the help of the following:

Jump to local IDE code directly from browser React component by just a simple click

Installation

npm i -D react-dev-inspector

Usage

Users need to add React component and apply webpack config before connecting your React project with 'react-dev-inspector'.

Note: You should NOT use this package, and React component, webpack config in production mode


 

1. Add Inspector React Component

import React from 'react'
import { Inspector, InspectParams } from 'react-dev-inspector'

const InspectorWrapper = process.env.NODE_ENV === 'development'
  ? Inspector
  : React.Fragment

export const Layout = () => {
  // ...

  return (
     {}}
      onClickElement={(params: InspectParams) => {}}
    >
     
       ...
     
    
  )
}


 

2. Set up Inspector Config

You should add:

  • an inspector babel plugin, to inject source code location info
    • react-dev-inspector/plugins/babel
  • an server api middleware, to open local IDE
    • import { launchEditorMiddleware } from 'react-dev-inspector/plugins/webpack'

to your current project development config.

Such as add babel plugin into your .babelrc or webpack babel-loader config,
add api middleware into your webpack-dev-server config or other server setup.


 

There are some example ways to set up, please pick the one fit your project best.

In common cases, if you're using webpack, you can see #raw-webpack-config,

If your project happen to use vite / nextjs / create-react-app and so on, you can also try out our integrated plugins / examples with

raw webpack config

Example:

// .babelrc.js
module.exports = {
  plugins: [
    /**
     * react-dev-inspector plugin, options docs see:
     * https://github.com/zthxxx/react-dev-inspector#inspector-babel-plugin-options
     */
    'react-dev-inspector/plugins/babel',
  ],
}
// webpack.config.ts
import type { Configuration } from 'webpack'
import { launchEditorMiddleware } from 'react-dev-inspector/plugins/webpack'

const config: Configuration = {
  /**
   * [server side] webpack dev server side middleware for launch IDE app
   */
  devServer: {
    before: (app) => {
      app.use(launchEditorMiddleware)
    },
  },
}


 

usage with Vite2

example project see: https://github.com/zthxxx/react-dev-inspector/tree/master/examples/vite2

example vite.config.ts:

import { defineConfig } from 'vite'
import { inspectorServer } from 'react-dev-inspector/plugins/vite'

export default defineConfig({
  plugins: [
    inspectorServer(),
  ],
})


 

usage with Next.js

use Next.js Custom Server + Customizing Babel Config

example project see: https://github.com/zthxxx/react-dev-inspector/tree/master/examples/nextjs

in server.js, example:

...

const {
  queryParserMiddleware,
  launchEditorMiddleware,
} = require('react-dev-inspector/plugins/webpack')

app.prepare().then(() => {
  createServer((req, res) => {
    /**
     * middlewares, from top to bottom
     */
    const middlewares = [
      /**
       * react-dev-inspector configuration two middlewares for nextjs
       */
      queryParserMiddleware,
      launchEditorMiddleware,

      /** Next.js default app handle */
        (req, res) => handle(req, res),
    ]

    const middlewarePipeline = middlewares.reduceRight(
      (next, middleware) => (
        () => { middleware(req, res, next) }
      ),
      () => {},
    )

    middlewarePipeline()

  }).listen(PORT, (err) => {
    if (err) throw err
    console.debug(`> Ready on http://localhost:${PORT}`)
  })
})

in package.json, example:

  "scripts": {
-    "dev": "next dev",
+    "dev": "node server.js",
    "build": "next build"
  }

in .babelrc.js, example:

module.exports = {
  plugins: [
    /**
     * react-dev-inspector plugin, options docs see:
     * https://github.com/zthxxx/react-dev-inspector#inspector-babel-plugin-options
     */
    'react-dev-inspector/plugins/babel',
  ],
}


 

usage with create-react-app

cra + react-app-rewired + customize-cra example config-overrides.js:

example project see: https://github.com/zthxxx/react-dev-inspector/tree/master/examples/cra

const { ReactInspectorPlugin } = require('react-dev-inspector/plugins/webpack')
const {
  addBabelPlugin,
  addWebpackPlugin,
} = require('customize-cra')

module.exports = override(
  addBabelPlugin([
    'react-dev-inspector/plugins/babel',
    // plugin options docs see:
    // https://github.com/zthxxx/react-dev-inspector#inspector-babel-plugin-options
    {
      excludes: [
        /xxxx-want-to-ignore/,
      ],
    },
  ]),
  addWebpackPlugin(
    new ReactInspectorPlugin(),
  ),
)


 

usage with Umi3

example project see: https://github.com/zthxxx/react-dev-inspector/tree/master/examples/umi3

Example .umirc.dev.ts:

// https://umijs.org/config/
import { defineConfig } from 'umi'

export default defineConfig({
  plugins: [
    'react-dev-inspector/plugins/umi/react-inspector',
  ],
  inspectorConfig: {
    // babel plugin options docs see:
    // https://github.com/zthxxx/react-dev-inspector#inspector-babel-plugin-options
    excludes: [],
  },
})


 

usage with Umi2

Example .umirc.dev.js:

  codeInfo?: {
    lineNumber: string,
    columnNumber: string,
    /**
    * code source file relative path to dev-server cwd(current working directory)
    * need use with `react-dev-inspector/plugins/babel`
    */
    relativePath?: string,
    /**
    * code source file absolute path
    * just need use with `@babel/plugin-transform-react-jsx-source` which auto set by most framework
    */
    absolutePath?: string,
  },
  /** react component name for dom element */
  name?: string,
}


 

Inspector Babel Plugin Options

interface InspectorPluginOptions {
  /** override process.cwd() */
  cwd?: string,
  /** patterns to exclude matched files */
  excludes?: (string | RegExp)[],
}


 

Inspector Loader Props

// import type { ParserPlugin, ParserOptions } from '@babel/parser'
// import type { InspectorConfig } from 'react-dev-inspector/plugins/webpack'

interface InspectorConfig {
  /** patterns to exclude matched files */
  excludes?: (string | RegExp)[],
  /**
   * add extra plugins for babel parser
   * default is ['typescript', 'jsx', 'decorators-legacy', 'classProperties']
   */
  babelPlugins?: ParserPlugin[],
  /** extra babel parser options */
  babelOptions?: ParserOptions,
}


 

IDE / Editor config

This package uses react-dev-utils to launch your local IDE application, but, which one will be open?

In fact, it uses an environment variable named REACT_EDITOR to specify an IDE application, but if you do not set this variable, it will try to open a common IDE that you have open or installed once it is certified.

For example, if you want it always open VSCode when inspection clicked, set export REACT_EDITOR=code in your shell.


 

VSCode

install VSCode command line tools, see the official docs
install-vscode-cli

set env to shell, like .bashrc or .zshrc

export REACT_EDITOR=code


 

WebStorm

  • just set env with an absolute path to shell, like .bashrc or .zshrc (only MacOS)
export REACT_EDITOR='/Applications/WebStorm.app/Contents/MacOS/webstorm'

OR

install WebStorm command line tools
Jump to local IDE code directly from browser React component by just a simple click

then set env to shell, like .bashrc or .zshrc

export REACT_EDITOR=webstorm


 

Vim

Yes! you can also use vim if you want, just set env to shell

export REACT_EDITOR=vim


 

How It Works

Stage 1 - Compile Time

  • [babel plugin] inject source file path/line/column to JSX data attributes props

Stage 2 - Web React Runtime

[React component] Inspector Component in react, for listen hotkeys, and request api to dev-server for open IDE.

Specific, when you click a component DOM, the Inspector will try to obtain its source file info (path/line/column), then request launch-editor api (in stage 3) with absolute file path.

Stage 3 - Dev-server Side

[middleware] setup launchEditorMiddleware in webpack dev-server (or other dev-server), to open file in IDE according to the request params.

Only need in development mode,and you want to open IDE when click a component element.

Not need in prod mode, or you just want inspect dom without open IDE (set disableLaunchEditor={true} to Inspector component props)

TensorFlow Lite Object Detection using Raspberry Pi and Pi Camera

I have not created the Object Detection model, I have just merely cloned Google’s Tensor Flow Lite model and followed their Raspberry Pi Tutorial which they talked about in the Readme! You don’t need to use this article if you understand everything from the Readme. I merely talk about what I did!

Prerequisites:

  • I have used a Raspberry Pi 3 Model B and PI Camera Board (3D printed a case for camera board). **I had this connected before starting and did not include this in the 90 minutes **(plenty of YouTube videos showing how to do this depending on what Pi model you have. I used a video like this a while ago!)

  • I have used my Apple Macbook which is Linux at heart and so is the Raspberry Pi. By using Apple you don’t need to install any applications to interact with the Raspberry Pi, but on Windows you do (I will explain where to go in the article if you use windows)
