The Cauchy-Schwarz Inequality

$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$
Create Your Own URL Shortener with Short.io for FreeEver wanted to have your own branded URL shortener? With Short.io, it’s quick, free, and easy! Here’s a simple step-by-step guide to get you started.

Preparations

A domain name  
A device with Internet access


Getting Started
Step 1: Register and Add Your Domain

Visit Short.io, create an account, and log in.
Once logged in, click Add Domain and enter your domain address.


Step 2: Configure DNS Records
After adding your domain, you’ll see two DNS records like these:  
| A    | @    | 52.21.33.16 |  
| ---- | ---- | ----------- |  
| A    | @    | 52.2.56.64  |  


Copy the DNS records and add them to your domain’s DNS settings on your domain registrar’s site (e.g., Namecheap, Cloudflare).  
IMPORTANT: Set the Proxy status to DNS Only mode.


Step 3: Wait for DNS Propagation

DNS updates may take up to 2 hours, but it’s often faster.  
To check progress, click REFRESH under Domain Settings on the Short.io dashboard.


Step 4: Start Creating Short Links
That’s it! You can now create branded short links via the Short.io dashboard. Customize your slugs and start sharing!  

Useful Official Links

Short.io Chrome Extension: Chrome Web Store link  
Short.io iOS App: App Store link  
Short.io Android App: Google Play link  
Short.io Telegram Bot: Bot link

To integrate the bot with your domain, create a secret API key here.  

Integration with Other Services
1. Integrate with ShareX

  "DestinationType": "URLShortener",  
  "RequestMethod": "POST",
