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.
