Investing is more my husband's purview, but I loved Gordon Bernhardt's tale of his walk and life stories, and that made reading the parts about investing actually enjoyable for me. The author's arduous journey on the Camino was fascinating and I couldn't wait for his next experience. He did an outstanding job of weaving together his walk, his investment philosophies, and the life lessons he learned along the way.

Great introduction to Linux kernel development

Format: Kindle

This is a great book for those wanting to get into Linux kernel development. It has a good flow to the writing and doesn't try and bury you with too much deep knowledge as a beginner (just enough to give you the basics of the concepts being discussed). if you purchase this book there is a second book with more depth on programming provided free (on the books website github). I enjoyed this book so much I've purchased the second book for my kindle reader to support the author. I've also purchased Kaiwan's book on Linux kernel debugging which is also an excellent read; giving you a good introduction to all the different methods/tools that can be used to help you debug those stubborn issues you'll inevitably encounter working as a kernel developer. I can't wait to read the next edition of this book coming out in January; revised for the 6.x kernel. FYI, I've read this book and worked through all the examples on the latest Linux stable kernel (as of this review 6.4.x/6.5.x-rcX). You won't regret getting this book if you want to start down the path of being a Linux kernel developer! I'd love to see a book from Kaiwan on developing module/drivers using Rust (with it's support now included in Linux kernel since 6.2). :-)

Excellent book with information presented in great depth

Format: Paperback

I would highly recommend this book to people interested in learning the internal working of the Linux kernel and writing kernel level code like device drivers. Everything is covered in great detail and where impractical many resources are provided to further explore the topic. Definitely a must read!
