I found a comment that was factually incorrect and I felt competent to comment on that. Regrettably, I wrote just one sentence and clicked reply without providing any credentials to back up my claim. Not that I try to hide my identity, as danhak pointed out in https://news.ycombinator.com/item?id=28751644, my full name and URL of my personal website are only a click away.
I have replied to my initial comment with provide some additonal context: https://news.ycombinator.com/edit?id=28752431. Hope that helps.
