Software Defect Indicator
A Software Defect Indicator is a pattern that can be found in source code that is strongly correlated with a software defect, an error or omission in the source code of a computer program that may cause it to malfunction. When inspecting the source code of computer programs, it is not always possible to identify defects directly, but there are often patterns, sometimes called anti-patterns, indicating that defects are present. Some examples of Software Defect Indicators: * Disabled Code: Code has been written and the programmer has disabled it, or switched it off, without making it clear why it has been disabled, or when or whether it will be re-enabled. * Routine Too Complex: A program (method, module, routine, subroutine, procedure, or any named block of code) contains more than 10 binary terms in conditional statements. * Unused Variables: Unreferenced variables are a strong indicator for other errors. * Number of Distinct Committers: The amount of unique developers that have mad ...

Source Code
In computing, source code, or simply code or source, is a plain text computer program written in a programming language. A programmer writes the human readable source code to control the behavior of a computer. Since a computer, at base, only understands machine code, source code must be Translator (computing), translated before a computer can Execution (computing), execute it. The translation process can be implemented three ways. Source code can be converted into machine code by a compiler or an assembler (computing), assembler. The resulting executable is machine code ready for the computer. Alternatively, source code can be executed without conversion via an interpreter (computing), interpreter. An interpreter loads the source code into memory. It simultaneously translates and executes each statement (computer science), statement. A method that combines compilation and interpretation is to first produce bytecode. Bytecode is an intermediate representation of source code tha ...
