Nobody Memorizes This Stuff

It's the-book-of-secret-knowledge — a giant, neatly categorized collection of cheat sheets, terminal tricks, networking commands, and cybersecurity resources, all in one MIT-licensed repo. Real developers cheat: one repo has all the cheat sheets, and you just search it.


Search, Don't Memorize

The stuff you use constantly but can never quite recall — Linux, Docker, Kubernetes, Regex, SSH, networking, security, and debugging tools — all neatly categorized so you land on the exact command, not a wall of forum threads. Instead of digging through ten forums for 40 minutes, you just search the repo. It's the encyclopedia for when your brain hits a wall.


What's in the Guide

How to use the repo, what it covers, and why it turns "a million open tabs" into one reliable place to look — aimed at sysadmins, DevOps, and security folks.

The full breakdown is in the PDF.
