It’s on GitHub: https://github.com/BloombergMedia/whatiscode
Obligatory source code: https://github.com/BloombergMedia/whatiscode
(I have a merged PR in there... do you? :))
The article mentions 'What is Code?' was open-sourced. Where is the repo?
Edit: Found it. https://github.com/BloombergMedia/whatiscode
Damn, the network graph looks like the devil's hot kitchen.
The activity on the article's accompanying github (https://github.com/BloombergMedia/whatiscode) is really interesting. Users have suggested edits not only to the code in the article but even to add citation.
This adds another dimension to the content by including the open source community such that the subject matter (coders) can influence (and improve!) their article's content.
