I kinda dislike the premise of your question, but https://www.amazon.com/Beautiful-Code-Leading-Programmers-Pr... has some good candidates. Chapter 1 for example is a regular expression matcher that appeared on HN recently: https://news.ycombinator.com/item?id=32589311

During my undergrad I semi-randomly picked out "Beautiful Code" [0] from our university library. Not sure why it never features in such lists but I thoroughly enjoyed it. :)

I thought I had seen it before. Verified you can actually see the whole chapter in a nicer (book vs web) layout in Amazon's "Look inside" feature since it's at the beginning of the book.

I have once already: https://www.amazon.com/Beautiful-Code-Leading-Programmers-Pr...

I liked it, but I'm not going to be paying for this sort of thing often. I think a lot would hinge on having content that was high quality, and being able to persuade me that it would be high quality before I paid for it might be challenging.

> How to write English (non-native language)

I suggest writing a blog in English. Practice is probably the best way to learn. There is also http://english.stackexchange.com if you have specific questions.

In my experience, reading other people's code is the best way to get better at a language. I don't have much experience with C but I guess there are a few projects that would be interesting to read here: https://github.com/search?o=desc&q=language%3A%22c%22&ref=si...

I believe one of the examples they gave in C was the diff algorithm from Subversion.

Chapter 28 in Beautiful Code (http://www.amazon.com/Beautiful-Code-Leading-Programmers-Pra...) talks about delta debugging, how it was invented and developed. its really a great chapter in a great book. i can't recommend it enough.
