Just bought this book and I must tell I'm really satisfied! So far so good Good job!
I post here to not open a new topic as this is quite a side question.
I'd like to know which tool/add-in the author has used for UML diagrams.
I'd really appreciate it as I would like to draw some of them by myself for my learning method.
Thanks a lot.
It's indeed what I've already started to do going through first 2 chapters.
My question was mainly, let me say curiosity, as I have not yet found an easy to use software to do that (tried latest Violet but it's like I'm missing something as I'm not able to draw many shapes...)
