Hi Everyone,

My publisher is running a free Amazon Kindle book promotion through Monday, August 25th, 2025. The book, “Eclipse Collections Categorically: Level up your programming game” can be obtained for $0 on Kindle on Amazon through the August 25th.

The Kindle version of the book can be read on a Kindle device or on any device where you can install and run the Kindle App. I’ve had the Kindle App for years on my MacBook Pro, and only just bought a Kindle a couple months ago to test that my book reads well on it with the default fonts. Unfortunately, I had to buy a full price copy of my book to test, but it was worth it. It took me 21 years to write this book, and the journey has been incredible. I keep my Kindle with the cover of my book on the desk next to me at home. My sister designed the cover, and I think it looks great. 

Books are expensive, and you have to be really committed to a topic for it to be worth the money. I hope many or all of you will take advantage of the free Kindle book promotion while it is available. If you’ve never had the time to check out Eclipse Collections in your programming journey, "Eclipse Collections Categorically" is the best consolidated reference available today. It also has some fun and interesting history in the Foreword, the Preface, and the Appendices. Feel free to tell your friends about the free book promotion as well. 

Thank you to everyone who already bought print or digital versions of the book. If you have a print version of the book already, I hope you will take advantage of the free Kindle book offer as a value added resource to the print version.

In addition to the free book promotion, there is now a GitHub repo with sample examples from the book. This is also a useful addition for folks who want to try out the examples from the book on their own in a project running Eclipse Collections 13.0, which is the latest EC release. The examples in the book are effectively the solutions to a Code Kata.

For those that haven’t heard, we released Eclipse Collections 13.0 this summer, and it is compatible with Java 17+. The current plan is for Eclipse Collections 14.0 to also be released on Java 17. Goodbye Java 8 and Java 11. The following was my release blog for the EC 12.0 and 13.0 releases.

For those attending or speaking at dev2Next, I will be there giving a talk on “Refactoring to Eclipse Collections” with fellow Eclipse Collections Committer, Vlad Zakharov. I can’t sign a copy of the Kindle book (unless you want to ruin your device), but I may have a couple of print copies with me in the talk for interested folks who attend to raffle off. If you bring your own print copy, of course I will be happy to autograph it for you.

Enjoy the rest of the summer, and hope to see some of you out in Colorado next month!

Thanks,

Don
