Arguments

1. The "Hard Stuff" Still Needs Factories

Planes, rockets, cars, ships, clothes, medical devices — all physical goods that require industrial-scale production.

Even your smartphone (the symbol of miniaturization) requires giant semiconductor fabs that cost $20–$30 billion each. That's not garage tinkering — it's industrial might.

"You can't 3D-print a Boeing 787 in your basement." Industrial capacity still matters.

Node.js Deployment

Steps to deploy a Node.js app to DigitalOcean using PM2, NGINX as a reverse proxy and an SSL from LetsEncrypt

1. Sign up for Digital Ocean

If you use the referal link below, you get $10 free (1 or 2 months) https://m.do.co/c/5424d440c63a

2. Create a droplet and log in via ssh

I will be using the root user, but would suggest creating a new user

const express = require('express');
const app = express();

// Application
app.get('/', function(req, res) {
  if (process.env.NODE_ENV === 'development') {
    for (var key in require.cache) {
      delete require.cache[key];
    }      
  }

In production, it is recommended to minify any JavaScript code that is included with your application. Minification can help your website load several times faster, especially as the size of your JavaScript source code grows.

Here's one way to set it up:

1. Install Node.js
2. Run npm init -y in your project folder (don't skip this step!)
3. Run npm install terser

Now, to minify a file called like_button.js, run in the terminal:
