In CS101, everyone writes a version of several search routines, several sorting routines, and many other common algorithms. In Chem101, you go through a number of common experiments. In a way, these are rites of passage, as well, but not the ones, I think, you're referring to.
in reply to "Rites of Passage" wheel reinventing
As for wheels ...
- A OO representation
- Numerous chess-validators
- Alpha-Beta algorithms (back when I was messing around with a Go-playing program)
- PDF::Template, Excel::Template, Graph::Template ... when I could've just written plugins for TT. (I'll write them, once we convert to TT.)
- And the one I'm least proud of - a scheduling algorithm for a small airline company, in Pascal.
We are the carpenters and bricklayers of the Information Age.
