Thanks a lot, that's quite valuable! I was hoping to introduce both new and old readers with the "Context" section, but it seems I failed at that. The new post contains all of the content of the previous one and extends it a bit, which is why I didn't link the old one. I removed the "Context" section now and replaced it with two short sentences addressed at readers of the previous post. I hope this makes it easier for new readers.
