White paper was a thing (https://en.wikipedia.org/wiki/White_paper) before people recently started using it to mean "any possibly technical information saved in a two-column PDF".
Let's not suggest that "white paper" is more appropriate than "blog post" or "HN comment" as a medium for partaking in the HN tradition of sharing some details about one's stack. I'd be hard-pressed to believe that OP was literally asking for one, too.
