I feel slightly uncomfortable posting this because it is dwarfed by everything else in the media right now, but it is what it is.
We often copyright what we write. We string together concepts and words that have been pushed together and pulled apart for thousands of years. I know that the English language is incredibly massive, but comprehensible strings must have some countable cardinality, even if it is countably infinite? Hence issues of copyright. And as words build everything we've got, I started thinking about issues of copyright and licensing in the building blocks of the Internet, coding. In code there are many ways to build an aspect of your program, whether it be a basic loop, a GUI, or an incredibly complex modeling algorithm.
"Programmers are notorious for going to a search engine when they get stuck on a problem and then copying and pasting code into their code without the necessary modifications. Unfortunately, this is most likely illegal unless the poster of the original code expressly granted usage rights to you."
So you can create, craft, a series of commands that accomplishes your goal more efficiently and with clearer, more transparent coding. And this code is naturally preferable as it offers new users to understand a code more readily and perhaps jump right in. I found this man's blog super interesting because he points to meach programmer having his/her own style, much akin to writing, and the fact that Microsoft has an incredible number of patents on sections of code. When comments are lifted from perhaps a search engine, citation in a comment is preferred and necessary, as to avoid legal trouble. I thought a little insight into copyright of a different realm was worthwhile.
