RedDuck Academy — Engineering Principles Template

Five judgement exercises in the language of your choice — nothing to build, everything to reason about.

---

An engineering-principles template by RedDuck. Fork it, work through the tasks in the language of your choice, push your work. The tasks are about spotting a flaw, naming it, and arguing the fix; the work is reviewed by reading the files you push, so nothing needs to build or run.

Built with

Area	Technology
Languages	TypeScript, Python, Java, C# — pick one and use it throughout
Task format	TASK.md brief + SOLUTION.md you fill in
Coding tasks	A starter file per language in src/; task 05 also ships tests/
Tooling	None — no build step, no dependencies, no runner

How it works

flowchart LR
    A[TASK.md brief] --> B{Coding task?}
    B -->|yes| C["src/ starter in your language"]
    B -->|no| D[SOLUTION.md]
    C --> D
    D --> E[Push to your fork]

Loading

Each task is a folder with a TASK.md brief and a SOLUTION.md you fill in. Coding tasks also have a src/ folder with a starter file in each supported language. Complete the starter for your language and leave the other languages as they are.

Tasks

#	Task	What you do	Code
01	01-common-sense-check	Find and fix a common-sense flaw	src/
02	02-recognize-bypass	Recognize when a bypass is available	write-up only
03	03-core-periphery	Apply core and periphery	src/
04	04-content-derived-factory	Build a content-derived factory	src/
05	05-adversarial	Break the system as an adversary	src/ + tests/

Getting started

No install, no build. Clone your fork, open 01-common-sense-check/TASK.md, and start reading.

Workflow per task

1. Read the task's TASK.md.
2. For a coding task, complete the starter file for your language in src/.
3. Write your answer in SOLUTION.md.
4. Commit and push to your fork.
