About the author

John Madieu is an embedded Linux and kernel engineer living in Paris, France. His main activity consists of developing device drivers and Board Support Packages (BSPs) for companies in domains including IoT, automation, transport, healthcare, energy, and the military. John is the founder and chief consultant of LABCSMART, a company that provides training and services for embedded Linux and Linux kernel engineering. He is an open source and embedded systems enthusiast, convinced that it is only by sharing knowledge that we can learn more. He is passionate about boxing, which he practiced for 6 years professionally, and continues to channel this passion through training sessions that he provides voluntarily.

I want to thank Jerôme Grard for his rather critical eye and his suggestions for improvement. I would also like to personally thank Pacôme Cyprien Nguefack, Claudia ATK, Elsie Zeufack, Loïca, and all those who participated directly or indirectly in the writing of this book, for accompanying me on this journey.

About the reviewer

Robertino Beniš has been involved in the embedded world for 15+ years, working on projects from smart homes and mobile devices (shipped 10+ million devices worldwide) to vehicle infotainment systems. He has worked with embedded Linux as well as with a number of real-time operating systems, including bare metal (does anyone still remember Qualcomm Brew?).

Currently, he is starting up NFTee Inc., California, in the blockchain engineering space, and studying Russian at Minsk State Linguistic University in Belarus.

Thanks to my (start-up) CEO, Kyle, for his understanding while I dedicated some time to reviewing this book, and to the city of Minsk as a whole, for enabling a clean, peaceful, and comfortable environment in which to study, work, and live.
