TikTok-like recommender Algorithm

Detailed Technical Algorithm for a TikTok-like Recommendation System

1. Introduction

The objective is to develop a recommendation system that maximizes user engagement by analyzing a multitude of user interaction signals to present the most appealing content. The system optimizes for two key metrics:

  • User Retention: Encouraging users to return to the platform.
  • Time Spent: Increasing the duration users spend on the platform per session.

Fix "Permission denied (publickey)" error when pushing with Git

"Help, I keep getting a 'Permission Denied (publickey)' error when I push!"

This means, on your local machine, you haven't made any SSH keys. Not to worry. Here's how to fix:

  1. Open git bash (Use the Windows search. To find it, type "git bash") or the Mac Terminal. Pro Tip: You can use any *nix based command prompt (but not the default Windows Command Prompt!)
  2. Type cd ~/.ssh. This will take you to the root directory for Git (Likely C:\Users\[YOUR-USER-NAME]\.ssh\ on Windows)
  3. Within the .ssh folder, there should be these two files: id_rsa and id_rsa.pub. These are the files that tell your computer how to communicate with GitHub, BitBucket, or any other Git based service. Type ls to see a directory listing. If those two files don't show up, proceed to the next step. NOTE: Your SSH keys must be named id_rsa and id_rsa.pub in order for Git, GitHub, and BitBucket to recognize them by default.
  4. To create the SSH keys, type ssh-keygen -t rsa -C "your_email@example.com". Th
