I found this single discussion? https://news.ycombinator.com/item?id=19453745

And that's by avoiding the word "topaz", where I see no story results with discussions and not much of comment results.

I can help (I added ''remaster''):

Links to the artciles found in those discussions are to some very enlightening efforts by Joel Hruska to find an upscaling solution related to what the person asked about. As somebody else mentioned, Topaz is out there and Hruska gave it a good shot, but it is not open source.

Right, I did find those, but only one had a discussion. Just making sure I'm not missing anything, so thanks for the clarification.
