The #1 EFI conversion system just got better! Introducing Sniper 2 EFI - a self-tuning, easy-to-install, EFI conversion for common 4-barrel (4150 flange) style carburetors. We took everything that we learned from the original Sniper EFI system and added 14 new features that will make your EFI conversion more simple, reliable, and modern. Like all Sniper EFI systems, Sniper 2 is designed to work with the Sniper Ecosystem that includes Hyperspark ignition, complete fuel systems, multiple user interfaces/dash displays, and more.
New for Sniper 2 is the optional Power Distribution Module (PDM). This cost-effective and optional accessory isolates the core of your EFI and ignition wiring into one, easy-to-use location. Simply slide the stripped wire ends under the positive lock connector and tighten down the set screw. Battery and a switched 12-volt source is all that's required from your vehicle to power the PDM and your Sniper EFI.
Make your classic drive like a modern fuel-injected vehicle, including easy cold starts, smooth drivability, and improved fuel economy! Sniper 2 is designed to be installed at home in your garage with limited tools and the support of Holley's comprehensive installation manual and videos. The user-friendly setup wizard allows you to answer a few simple questions about your engine and the system will begin self-tuning with no laptop or tuning experience required.
If you're looking for a high-performance fuel injection system that delivers power, efficiency, and ease of use, look no further than the Sniper 2 EFI.

Fine so far.
Format: Paperback
I am looking for some of the code from exercises, but can't find it in the project files, and they say don't copy it from the ebook...?

Very comprehensive and approachable
Format: Kindle
This e-book covers everything starting from basic general programming concepts and Godot development, going into (relatively) advanced game development programming patterns that are used throughout the industry. It explains not only what the best practices are but why they are used in a simple and understandable way, and provides points of reflection and knowledge testing with quiz sections. I highly recommend this book for anyone wanting to learn game development as a hobby, anyone interested in learning Godot, and even for anyone trying to learn game programming in general and wanted a simple place to start.

Not a Scripting Book. Wrong title, should read " Learn Godot for Beginners"
Format: Paperback
The book was not designed to focus on GDscript, it had a snippets for basic game interactions, but was primarily a make a simple game in Godot. I returned it.

Excellent guide for those seeking to learn.
Format: Paperback
I highly recommend this book if you are getting into Godot and want something tangible to sift through. the Book does an excellent job of explaining and curating a good foundation by explaining and stepping you through the Nodes and their purposes and potential usage. it touches on multiplayer(client synchronization, etc), and other fantastic aspects like object pools and a brief intro into state machines that reflect a professional environment that respects your intelligence but still graceful enough for beginners to digest, understand and grow their own creative projects from these roots.

Masterful, Hilarious, and Insightful
Format: Hardcover
The writing style reminded me at times of Michael Lewis ("The Big Short", "The New New Thing") in the way Jason Schreier captures the madness of gaming executives trying to succeed despite their bosses. The way the book describes various antics often had me chuckling or even laughing out loud: "As Pardo's responsibilities grew and his time became stretched between projects, he became known for what many of his subordinates called seagull management: He would swoop down, poop on ideas, and then fly away." It's full of insight about what makes a good game, or even a good remake of a game: "One tenet, adapted from legendary Civilization designer Sid Meier, was that one-third of the units should return from the old game, one-third should be modified versions, and one-third should be brand-new." This book is masterful. I found it impossible to put down: one of the very best books I've ever read about a games company, or any company for that matter. If you are in the games industry, you like reading about crazy businesses or you just like games, get it.
