Thinking Like a Programmer
Like Duolingo, but for Thinking Like a Programmer. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
A short one: 15 levels across 2 sections, about 30 minutes end to end, roughly 6 days at five minutes a day. It moves through Giving Clear Instructions and Building Efficient Patterns. It starts from scratch.

Key ideas in Thinking Like a Programmer
- Computers cannot fill in gaps or infer intent
- The computer processes one line at a time
- Instructions must be broken down into literal, primitive actions
- Information must be defined before it can be used in a later step
- Speed does not compensate for a lack of common sense
- The order of lines determines the logic of the program
- The computer's lack of intuition and need for literal instructions
- The strict top-to-bottom execution of code
- Computers require a specific format to translate text into actions
- Syntax acts as the 'language' the machine is hard-wired to read
- A single character error can stop the entire translation process
- The role of syntax as the bridge between human logic and machine action
- Computers cannot 'guess' past a broken chain of logic
- The computer completely skips over comments during execution
- Comments are used to explain the 'why' of code to other people
- The fragility of code and the impact of minor errors
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Thinking Like a Programmer the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
