Months ago, I was looking for a book on Design Patterns. I already own the great classic GoF and a few more, but I was looking for a more practical, real-world exposition of the classic Patterns. I wanted a book I could recommend to new developers, so they could really learn how to apply the concepts.
I came across Holub On Patterns. I liked it, but I was disappointed with the editorial quality of the book.
I found a long list of errors. Some of them are minor, but still may confuse readers, specially those new to the topic.
