Use Static Single-Assignment when possible This post discuss a way of coding assignments in code where all variables are treated as constants. Introduction There are simple ways to improve our source code that are simple but effective. Static Single-Assignment (SSA) is one of them. By changing the way variable assignments are done, we can achieve some benefits in maintainability that cannot be overlooked. What is Static Single-Assignment? Just treating the variables as constants, i. [Read More]

Donald E. Knuth coined the term Literate programming in this paper he wrote almost 40 years ago. Knuth wrote a tool called WEB as a demonstration of what Literate Programming should be. This tool would understand Pascal and TeX code, using Pascal code to create a binary executable and using TeX code to compile its documentation file. Pascal code would be a bit different because of the use of predefined macros and it would be interleaved by TeX code describing what actions execute. [Read More]
