Hey, everyone. As you know, I am not particularly present recently (I need to find out how to handle this blog while my interests spread out on non-technical stuff, but this is something for another time).

However, I am back with an announcement: I have recently published the fifth edition of Unity Artificial Intelligence Programming.

Not only have I updated the book for Unity 2022, but the book is also a massive improvement over the last edition in terms of code quality and consistency (and I really need to thank Kazimieras Mikelis for the extensive and detailed review). Moreover, I added a chapter on Procedural Content Generation because it is my main interest, of course.

With this new year, let’s try a new format. Marginalia will be a series in which I’ll share notes and comments on interesting books I read. The name is directly inspired by the old word indicating the small notes on the margins of books.

It will be a chance to discuss my readings without the need to write a full-fledged article. I hope it will be interesting as a review of the book or as a discussion starter. So, let’s start.

The new edition of Unity Game Optimization is finally out! I already announced that in my December monthly update, but I think it is worth to spend a bit more words on it.

Some time ago I found on my grandma’s house an old Italian book on cryptography from 1897. Why a 120 years old book on cryptography was on my grandma house, is a mystery. I’d like to think that some grand-grand-parent was a late 19th century hacker. Anyway.

The book title is “Crittografia ossia l’arte di cifrare e decifrare le corrispondenze segrete” of Count Luigi Gioppi of Turkheim.

Well, I don’t know if this book is hard to find. In any way, I decided to take a photo of every page to share and preserve this book. The book is very old and some page is ruined, sorry if the quality of the photo is not optimal. I’ve done my best for not destroying the book in the process. :) I will release the photo one chapter at the time. Keep this page in the bookmark.
