Standby Generator, 20kW | Diesel | 1800rpm
All the conveniences of modern living - heat, central air, refrigeration, communication - are nothing without power. When the power supply is disrupted, our lives and businesses can come to a sudden halt. An automatic standby generator protects you from power failures, restoring power within seconds of an outage, so you can have peace of mind and the power you need.
Features
- Generac's new Protector® Series diesel generators raise the bar for residential and light commercial diesel generators. Building and zoning codes can vary wildly from one region to another. In the past, the only answer was to order expensive, custom-configured solutions. Until now.
- Generac's diesel-powered Protector Series features Code Ready, a set of popular preconfigured options and a range of code-driven accessories, so you can feel confident that your generator will be able to conform to the required local codes. The Protector Series is versatile, adaptable, meets UL requirements, and is an affordable optional standby diesel generator for your backup power needs.
- Evolution Controller
The next generation of intuitive controllers featuring a multilingual, two-line LCD text display with color-coded, backlit buttons. - Quiet-Test mode
All standby generators run a weekly test to ensure the system is running properly. Thanks to Quiet-Test, your Protector Series standby generator runs its self-test at a lower, quieter RPM than standard operation. - Mobile Link Connectivity allows you to monitor the status of your generator from anywhere in the world using a smartphone, tablet or PC. Easily access information, such as the current operating status and the generator's maintenance schedule. Connect your account to an authorized service dealer for fast, friendly and convenient assistance. With Mobile Link, your generator is taken care of before the next outage.
Mobile Link™ comes standard with Protector Series 22 - 100 kW gaseous models and diesel (RD) models. The Wi-Fi device is standard on every Protector series generator except for the RG13090/RG15090 and the 130 - 150 kW gaseous models. - Code Ready
The Protector Series offers compatibility with a variety of environments, with external vent and fill, a UL/CUL 142-listed, double-walled base tank, a UL/CUL 2200-listed generator, and a wide range of code-driven accessories.

There's nothing else out there that's this comprehensive
Format: Hardcover
Unlike my last review, this one I'm happy to write. I'm a game engine programmer, but I don't have a long history with games, and how their engines are typically structured. Every in-house AAA engine will be different of course, and obviously you won't find books (or typically any docs at all really) on the structure of these behemoths, so the best you can hope for is something that tries to give you the high level overview of what to look for - how a tools pipeline is setup, what subsystems to expect, how they interact, etc.
This book provides all of that, and so, so much more. I really can't believe how much is packed in this thing. A really nice section on OS fundamentals, extensive coverage of concurrent programming, tools, audio, physics, it's all there (in one way or another). Like most of these kinds of books, you probably don't want to try and read it front to back (although that would be awesome, who has the time for that?) Instead, I've been going to sections on an as-needed basis and picking up just the stuff I need most at that time, and it's been great.
I'm at the point in my career where I'm just not buying as many books as I used to, either because they don't deliver on their promises, they only cover the basics, or they just rehash things that have already been covered extensively in other books. This book's definitely got me excited, because it provides a ton of real-world info that's hard to get anywhere else. 100% recommend to anyone new to game engine software development.
UPDATE: 6 months later, and this book continues to amaze. After studying every line of code in the section on memory allocators, I've added this feature to my engine and it works great. Same with quaternions. I just keep finding myself reaching for this book! What a great resource, rock solid.

Don't peek at the next page.
Format: Hardcover
Basically, best practices in game engine architecture, citing a wide array of game engines used by a wide array of top game makers.
Out of a ~1150 page book:
The longest chapter is ~150 pages, on Parallelism and Concurrent Programming.
Rendering Engine is ~100 pages
Collision and Rigid Body Dynamics is ~100 pages
3D Math for Games is ~50 pages
I had hoped for treatments on quaternion camera and for entity component system, but alas, no.
What I did get was still crucial. The most illuminating guidance was in Engine Support Systems (~50 pages) which talked about best Memory Management, and in Game Loop and Real-Time Simulation which talks about ideal orders of operations in a highly efficient game loop.
The first 400 pages of this book are not exclusive to games. A new programmer that wants to do high performance programming can gain a lot from this before it gets into 'primarily' game topics.
My strategy for getting through this whale was to never peek at the next page. I did not read (Character) Animation Systems (~100 pages) or Audio (~100 pages), as I do not need them at this time.
You can certainly damage the book if you don't keep in mind its weight, or if you do that maneuver where you forcibly open it against its spine. I did that and the binding popped off the backing. It's all in one piece, and it's easier to read. It's a big tome.

The Bible, if it was good
Format: Hardcover
I’m not kidding when I say the first 350 pages of this book are quite literally an entire computer science degree. In fact, many CS majors would learn more about some of these subjects here than in their classes. I’m incredibly impressed with the thoroughness and depth of this absolute tome, and I’ll be far more impressed if the binding is able to hold on to all 1200 pages for the whole time it takes me to read it.
