She has written a brilliant and utterly compelling new adventure, which begins with the words:

“The hottest day of the summer so far was drawing to a close and a drowsy silence lay over the large, square houses of Privet Drive…. The only person left outside was a teenage boy who was lying flat on his back in a flowerbed outside number four.“Later in the novel, J.K. Rowling writes:

“Dumbledore lowered his hands and surveyed Harry through his half-moon glasses. ‘It is time,’ he said ‘for me to tell you what I should have told you five years ago, Harry. Please sit down. I am going to tell you everything.’-Barbara Marcus, President of Scholastic Children’s Books in the United States, and Nigel Newton, Chief Executive of Bloomsbury Publishing in Britain

Site Reliability Engineering: How Google Runs Production Systems pdf free download by Betsy Beyer, Chris Jones, Jennifer Petoff, Niall Richard Murphy

Site Reliability Engineering: How Google Runs Production Systems pdf free download by Betsy Beyer, Chris Jones, Jennifer Petoff, Niall Richard Murphy

Description:

The overwhelming majority of a software system’s lifespan is spent in use, not in design or implementation. So, why does conventional wisdom insist that software engineers focus primarily on the design and development of large-scale computing systems?

In this collection of essays and articles, key members of Google’s Site Reliability Team explain how and why their commitment to the entire lifecycle has enabled the company to successfully build, deploy, monitor, and maintain some of the largest software systems in the world. You’ll learn the principles and practices that enable Google engineers to make systems more scalable, reliable, and efficient—lessons directly applicable to your organization.

This book is divided into four sections:

  • Introduction—Learn what site reliability engineering is and why it differs from conventional IT industry practices
  • Principles—Examine the patterns, behaviors, and areas of concern that influence the work of a site reliability engineer (SRE)
  • Practices—Understand the theory and practice of an SRE’s day-to-day work: building and operating large distributed computing systems
  • Management—Explore Google’s best practices for training, communication, and meetings that your organization can use

The really liked this book. Cool to see how Google actually runs things at their scale. Got me thinking about things I never thought about when it comes to my work in tech. This could sound like the book makes you paranoid, but I think that’s too negative. I felt more like I now have a little license and education on how things can (and will) fail and how I can better prepare for and mitigate them. It’s like you got to do a ride along in a busy Ambulance service, gets you thinking “hmm, maybe I should take that CPR course and brush up on the heimlich maneuver…”.

Managing 12 Volts: How to Upgrade, Operate, and Troubleshoot 12 Volt Electrical Systems by Harold Barre pdf free download

Managing 12 Volts: How to Upgrade, Operate, and Troubleshoot 12 Volt Electrical Systems by Harold Barre pdf free download

Description:

How to upgrade, operate and troubleshoot 12-volt systems with emphasis on understanding what may be wrong with a system and how to improve it with a multi-stage charging system. Excellent diagrams, clear, concise writing.

for a long time now, i was looking for a “start from scratch” book in understanding auto electronics. a book with illustrations that actually explains how it works. this book is a great introduction, a must buy if you really want to know the fundamentals. even though it’s about RV’s too, it tells you all you need to know about autos.
the more you read, the better you understand what you read.
i now know how the battery really works, know what it really does, what the altenator does. i know about switches, sensor,actuators and solenoids now. at first you you need time to grasp the concept, but it gets easy to understand very quickly. 5 stars.

I have a bunch of motorcycles, a camper with generator/inverter/converter, trailers etc, all of which have batteries that need to be stored/ charged/ used. This book helped me FULLY understand each system and how to get the most out of it. This book explains EVERYTHING about 12v and 6v batteries and system operations. From solar, to charging etc.

I have purchased multiple copies to give as gifts to anyone I have known to struggle with replacing motorcycle, lawnmower, tractor or camper batteries every year because they don’t understand fully proper setup, maintenance, and charging of batteries.

Excellent source of information about your 12-volt system. Explains things in plain English, you don’t have to be an electrician to understand the contents. If you have a trailer, toy hauler, or motorhome with a 12-volt system, get it and keep it in the RV. You’ll be glad you did!
