Hello everyone, I am a little late to the party, but I finally had time to check the blog from Mihai, and it reads extremely well, it goes into enough details to be valuable even for people already knowing Calcite, but at the same time it's great introductory material.
I'd be happy to read more blog posts like that, thanks for sharing!
