+ Introduction
+ There are lots of laws which people discuss when talking about development. This repository is a reference and overview of some of the most common ones. Please share and submit PRs!
+ Note: This repo contains an explanation of some laws, principles and patterns, but does not advocate for any of them. Whether they should be applied will always be a matter of debate, and greatly dependent on what you are working on.

+ 90–9–1 Principle (1% Rule)
+ The 90-9-1 principle suggests that within an internet community such as a wiki, 90% of participants only consume content, 9% edit or modify content and 1% of participants add content.
+ Real-world examples:
+
+ - A 2014 study of four digital health social networks found the top 1% created 73% of posts, the next 9% accounted for an average of ~25% and the remaining 90% accounted for an average of 2%.

+ 90–90 Rule
+ The first 90 percent of the code accounts for the first 90 percent of the development time. The remaining 10 percent of the code accounts for the other 90 percent of the development time.
+ This is a wry reinterpretation of the Pareto Principle (or 80-20 rule) that highlights the real-world challenges of completing engineering work. This sentiment is also echoed in Hofstadter's Law.
