Q for Mortals Version 3 is a thorough presentation of the q programming language and an introduction to the kdb+ database. It is a complete rewrite of the original Q for Mortals that is current with q3.3. The presentation is derived from classes taught by the author at international financial institutions over the last decade. It is a series of tutorials based on q snippets intended to be entered interactively into the q console by the reader. The text takes its subject seriously but not itself. Technical explanations are augmented by mathematical observations, references to general programming concepts and other programming languages, and bad jokes. Coding style recommendations and advice to avoid gotchas appear liberally throughout. Examples are as simple as they can be but no simpler. Chapter 1, Q Shock and Awe, provides a piquant panorama of the power of q and its dazzling zen-like nature. Chapter 2 describes the base data types of q. Chapter 3 discusses lists, the fundamental data structure of q Chapter 4 presents the basic operators. Chapter 5 introduces dictionaries, which associate keys and values. Chapter 6 presents an in-depth description of functions and q's constructs for functional programming. Chapter 7 demonstrates transforming data from one type to another. Chapter 8 introduces tables and keyed tables, the fundamental data structures for kdb. Chapter 9 describes q-sql and all the methods to manipulate tables. Chapter 10 presents ways to control execution of q programs. Chapter 11 covers file and interprocess communication I/O Chapter 12 describes workspace organization and management. Chapter 13 discusses system commands and command line parameters. Chapter 14 serves as an introduction to the kdb+ database. Chapter A has a complete rundown of the built-in functions. Chapter B lists common error messages. A cross-referenced index closes the book.

Practical problems and examples, Pragmatic programming practices in Q and Pure Pleasure of Reading
After reading several tutorials and materials on Q programming language and Kdb+ system, I think that q For Mortals Version 3: An Introduction to q Programming is most probably the best way to dive into the world of Kdb+ and Q programming. Jeffry A. Borror has a very pragmatic approach to Kdb+ and Q as efficient software development tools. Jeffry is very helpful in explaining how Q and Kdb+ establish their unique value in the context of declarative programming paradigm. The book was thought of as a very practical tutorial, so downloading a free copy of Kdb+ from the kx.com website, would help a reader to grasp the true power of Q. In summary, q For Mortals Version 3: An Introduction to q Programming is a mix of practical problems and solutions, pragmatic Q programming practices and flavored with a perfect sense of humor of a Q-God, Jeffry A. Borror.

Good Content, low quality paper and print.

I’m really disappointed: The quality of medium on which this book is printed (photocopied?) is questionable. The paper quality is 80gsm A4 size, with a standard sized (24/19cm) book’s text zoomed on to it; A university student with a photocopying card would achieve similar. At £65 this book is a physical embarrassment. As for the content, I can’t fault it. However, unless one is a ultra power user, then the book “Q Tips: Fast, Scalable and Maintainable Kdb+” is a better option. That book comes in ebook format, which for a freelancer as my self, is essential. If "Q For Mortals Version 3" came in ebook format I would buy it immediately. For now, I will keep using the version 2 of this book, that I bought from a second hand store.

Great Content - Shame about the size and weight

A great reference and much improved over the previous edition. It is a shame that the book is so large in format and heavy. It simply does not travel well nor fit in my knapsack. It is as if the author wanted accommodate those who can't find their reading glasses!
The original format was perfect. Offering a Kindle version of the book would be ideal so one can read the book on my tablet (offline).
