“Don’t comment bad code – rewrite it.” — Brian W. Kernighan and P. J. Plaugher If our programming languages were expressive enough, or if we had the talent to subtly wield those languages to...
Code Smell – Bad Smell in Code :: Understanding Long Parameter
The ideal number of arguments for a function is zero (niladic). Next comes one (monadic), followed closely by two (dyadic). Three arguments (triadic) should be avoided where possible. More than three (polyadic) requires very...
Code Smell – Bad Smell in Code :: understand Long Classes
Understand Long Classes. Its like a Big BOM or Big Class. In an effort to make our classes and methods small, we might create too many tiny classes and methods. So this rule suggests...

Understanding Long Method In an effort to make our classes and methods small, we might create too many tiny classes and methods. So this rule suggests that we also keep our function and class...
Code Smell – Bad Smell in Code :: Duplicate code
Repeatation is the root of software evil. Every time you see duplication in the code, it represents a missed opportunity for abstraction. That duplication could probably become a subroutine or perhaps another class outright....
