Insert mode isn't just 'press i and type'. Learn the nine ways to enter it, the keyboard shortcuts inside it, and the golden rule that separates Vim beginners from people who actually know what they're doing.

You already know how to make decisions with if. Now learn how to repeat them. while loops execute code over and over as long as a condition holds — and yes, infinite loops are very real.

Learn to open shells inside containers, run commands in live containers with docker exec, copy files with docker cp, and know when to use interactive vs. detached mode.

Learn how to use git cherry-pick to apply specific commits from one branch to another—perfect for backporting hotfixes, rescuing buried work, and surgical history management.

Learn how to use git rebase -i to reorder, combine, rename, and delete commits before integrating your work. Take full control of your history, commit by commit.

From writing code to directing AI: understand the new mental model, which tasks are worth delegating and which aren't, and why clarity of thought is now your most valuable skill.

Understand how Large Language Models work under the hood — no equations, just the mental models that explain why they hallucinate so confidently and how to use that to your advantage.

Normal mode isn't just where you land between keystrokes — it's where Vim lives. Learn word movements, the operator+motion grammar, and how a handful of keys gives you near-infinite editing power.

Your code has always executed the same instructions in the same order. With if, elif, and else, it can finally make decisions. Learn to write programs that react to data.

What exactly is a Docker image, how are layers stacked, and what happens to a container when it stops? The image-container relationship is the mental model everything else depends on.

Install Docker on Linux, macOS, or Windows and run your first container. Docker's architecture, the image vs container distinction, and the essential commands to get started.

Python's error messages are your best ally — if you know how to read them. Learn to decode tracebacks, understand the most common beginner mistakes, and build a debugging mindset from day one.
