Checkout the video below of Kevlin Henney presenting on “Code” at Agile2011. Kevlin looks into code. It is the definition of the software. It is the enabler of functionality, the realizer of business value, the expression of understanding. It is also an expression of misunderstanding, a resister of change, a source of sunk costs. But the word code has meanings beyond source and binary. In a broader sense, code and codes are also the stuff of software development. There are cultures of programming, principles of practice, manifestos of desire. Code refers to a set of conventions by which a group of people will govern themselves.
