Author of the blog post. It's just being a non-native speaker and writing the blog post by hand shows these little mistakes. I've been using the terms "code" and "codes", but you might very well be right that my usage is not entirely correct. I'll ask native speakers what the proper usage is here.
It's very common among scientific programmers to call programs "codes," native speaker or not. It's just a quirk of different computing communities evolving differently.
I do come from the scientific community, so didn't know until today that not every community uses the term "codes".
