Here is the link to part 3 of the blog series: https://blog.openzeppelin.com/blog/deconstructing-a-solidity-contract-part-iii-the-function-selector-6a9b6886ea49

If you scroll to the bottom and try to go to part 4, it redirects to wordpress.com so we can't view that article.

Also, the github gists for the code provided don't exist anymore.
