This book takes a humorous slant on the programming practice manual by reversing the usual approach: under the pretence of teaching you how to become the world's worst programmer who generally causes chaos, the book teaches you how to avoid the kind of bad habits that introduce bugs or cause code contributions to be rejected.




Why be a code monkey when you can be a chaos monkey? OK, so you want to become a terrible programmer. You want to write code that gets vigorously rejected in review. You look forward to reading feedback plastered in comments like 'WTF???'. Even better, you fantasize about your bug-ridden changes sneaking through and causing untold chaos in the codebase. You want to build a reputation as someone who writes creaky, messy, error-prone garbage that frustrates your colleagues. Bad Programming Practices 101 will help you achieve that goal a whole lot quicker by teaching you an array of bad habits that will allow you to cause maximum chaos.




Alternatively, you could use this book to identify those bad habits and learn to avoid them. The bad practices are organized into topics that form the basis of programming (layout, variables, loops, modules, and so on). It's been remarked that to become a good programmer, you must first write 10,000 lines of bad code to get it all out of your system. This book is aimed at programmers who have so far written only a small portion of that. By learning about poor programming habits, you will learn good practices. In addition, you will find out the motivation behind each practice, so you can learn why it is considered good and not simply get a list of rules.







What You'll Learn

Become a better coder by learning how (not) to program

Choose your tools wisely

Think of programming as problem solving

Discover the consequences of a program's appearance and overall structure

Explain poor use of variables in programs

Avoid bad habits and common mistakes when using conditionals and loops

See how poor error-handling makes for unstable programs

Sidestep bad practices related specifically to object-oriented programming

Mitigate the effects of ineffectual and inadequate bug location and testing






Who This Book Is For




Those who have some practical programming knowledge (can program in at least one programming language), but little or no professional experience, which they would like to quickly build up. They are either still undergoing training in software development, or are at the beginning of their programming career. They have at most 1-2 years of professional experience.



Karl Beecher is a British writer, software developer and teacher based in Berlin, Germany. He specializes in taking meaty, complex ideas and presenting them in ways that are easy to understand.

Inhalt/Kritik

Inhaltsverzeichnis
Chapter 1: Fundamentals of Badness

How best to approach programming, in particular how to learn it, how to choose your tools wisely, and how to

think of programming as problem solving.

¿ Bad ways to learn programming

¿ Bad tooling

¿ Bad ways to approach a solution (or: programming is really problem-solving)

Chapter 2: Layout and Structure

Show the reader the consequences of a program's appearance and overall structure.

¿ Make indentation and spacing poor and inconsistent

¿ Avoid structured programming, use lots of gotos

¿ Nest deeply - programmers like solving intricate puzzles

¿ Have lots of paths through a subroutine

¿ Clutter the code with extraneous tokens

¿ Avoid comments - code should be hard to read!

Chapter 3: Variables

Explain poor use of variables in programs.

¿ Use obscure names - thinking up meaningful labels isn't worth the effort

¿ Consider declaration a waste of time

¿ Use global variables

¿ Thoroughly abuse the type system

Chapter 4: Conditionals

Discuss bad habits and common mistakes when using conditionals.

¿ Use long, complex expressions

¿ Forget the else clause - the computer will figure it out

¿ Mix up nominal cases with errors cases

¿ Make sure the cases overlap or have gaps

Chapter 5: Loops

Discuss bad habits and common mistakes when using loops.

¿ Make 'em looooong!

¿ Give loops lots of exit points

¿ Avoid iterators - loop counters help make code convoluted and insecure

¿ Infinite loops are fun

Chapter 6: Subroutines

Show the consequences of poorly-written subroutines.

¿ Write monolithic programs - after all, someone else will do the maintenance

¿ Make subroutines long and complex

¿ Use lots of local variables

¿ Use inconsistent return values to keep your colleagues on their toes

Chapter 7: Error-handling

Explain how poor error-handling makes for unstable programs.

¿ Never check inputs - users don't make mistakes

¿ Don't handle errors - just assume everything will always go well

¿ Don't check for null pointers

¿ If you must check values, do it as late as possible (a.k.a. defensive programming is for wimps)

Chapter 8: Modules

Discuss bad practices to follow when dividing a large program into pieces.

¿ Make modules big and hefty

¿ Ensure they expose their inner workings

¿ Give them rigid designs to prevent others from writing their pesky extensions

¿ Make them specific to one problem - why should others benefit from your work?

¿ Import all the things!

Chapter 9: Objects

Discuss bad practices related specifically to object-oriented programming.

¿ Expose a class's internals - why should we have secrets?

¿ Put unrelated stuff together

¿ Objects are not independent - make them follow orders

¿ Keep coupling tight

¿ Favour deep inheritance hierarchies

¿ Avoid polymorphism - abstract code is harder to 'get' than abstract art

¿ Give classes multiple parents (a.k.a. classes shouldn't reproduce asexually)

Chapter 10: Bugs and debugging

Show how to carry out ineffectual and inadequate ways to locate bugs and mitigate their effects.

¿ Write really unfriendly error messages - users shouldn't understand them anyway

¿ Don't discriminate between exception types

¿ Litter code with print messages

¿ Don't use debug levels

Chapter 11: Testing

Show how to carry out ineffectual and inadequate testing.

¿ Ignore the requirements when testing

¿ Leave testing until the very end

¿ Keep code coverage low

¿ Testing once is enough

¿ Avoid test automation tools
