Samenvatting

This philosophy-of-programming guide presents a unique and entertaining take on how to think about programming. A collection of 21 pragmatic rules, each presented in a standalone chapter, captures the essential wisdom that every freshly minted programmer needs to know and provides thought-provoking insights for more seasoned programmers.

Author Chris Zimmerman, cofounder of the video game studio Sucker Punch Productions, teaches basic truths of programming by wrapping them in memorable aphorisms and driving them home with examples drawn from real code. This practical guide also helps managers looking for ways to train new team members.

The rules in this book include:
- As simple as possible, but no simpler
- Let your code tell its own story
- Localize complexity
- Generalization takes three examples
- Work backward from your result, not forward from your code
- The first lesson of optimization is don't optimize
- A good name is the best documentation
- Bugs are contagious
- Eliminate failure cases
- Code that isn't running doesn't work
- Sometimes you just need to hammer the nails

The Story of the Rules
How to Disagree with the Rules

1. As Simple as Possible, but No Simpler
Measuring Simplicity
But No Simpler
Sometimes It's Better to Simplify the Problem Rather than the Solution
Simple Algorithms
Don't Lose the Plot
One Rule to Rule Them All

2. Bugs Are Contagious
Don't Count on Your Users
Automated Testing Can Be Tricky
Stateless Code Is Easier to Test
Audit State You Can't Eliminate
Don't Trust the Caller
Keeping Your Code Healthy

3. A Good Name Is the Best Documentation
Don't Optimize for Minimal Keystrokes
Don't Mix and Match Conventions
Don't Shoot Yourself in the Foot
Don't Make Me Think

4. Generalization Takes Three Examples
YAGNI
An Obvious Objection to This Strategy, in Response to Which I Double Down
It's Actually Worse than YAGNI
This Is Not What Success Looks Like

5. The First Lesson of Optimization Is Don't Optimize
The First Lesson of Optimization
The Second Lesson of Optimization
Putting the Second Lesson to the Test
Step 1: Measure and Attribute Processor Time
Step 2: Make Sure There’s Not a Bug
Step 3: Measure Your Data
Step 4: Plan and Prototype
Step 5: Optimize and Repeat
Applying the Five-Step Optimization Process
There Is No Third Lesson of Optimization
Interlude: In Which the Previous Chapter Is Criticized

6. Code Reviews Are Good for Three Reasons

Shooting Myself in the Foot via a Ricochet
Enlisting the Compiler's Aid to Avoid Shooting My Foot
Timing Is Everything
A More Complicated Example
Making Ordering Mistakes Impossible
Using Templates Instead of Method Chaining
Coordinated Control of State
Detecting Mistakes Is Good, but Making Them Impossible to Express Is Better
