About This Book

In CODE, they show us the ingenious ways we manipulate language and invent new means of communicating with each other. And through CODE, we see how this ingenuity and our very human compulsion to communicate have driven the technological innovations of the past two centuries.

Using everyday objects and familiar language systems such as Braille and Morse code, author Charles Petzold weaves an illuminating narrative for anyone who’s ever wondered about the secret inner life of computers and other smart machines.

It’s a cleverly illustrated and eminently comprehensible story—and along the way, you’ll discover you’ve gained a real context for understanding today’s world of PCs, digital media, and the Internet. No matter what your level of technical savvy, CODE will charm you—and perhaps even awaken the technophile within.

CODE by Charles Petzold is the book to read to understand computers at a base level. It literally starts at a single bit and moves all the way up the stack. I cannot recommend this book enough for someone starting out.

Get the book CODE by Charles Petzold. It's a super easy read, and by the time you're done with it you'll understand how CPUs work.

Well done. This video seems to be based on the book Code by Charles Petzold, if you were interested in this video I highly recommend you read this book!

Chapter 22 of "Code: The Hidden Language of Computer Hardware and Software" uses CP/M to illustrate the inner workings of operating systems. I highly recommend this book overall: https://www.amazon.com/Code-Language-Computer-Hardware-Softw...

While a formal education covers most of these questions, they are still important to brush up on every now and then. My next book I will be reading is something that I believe might fall in line with what you're looking for.

Just to include a slightly different angle, the author of this book gives a fascinating description of how you could build analog mechanical logic gates using telegraph switches.

You'll do little to no traditional math but you will use Boolean Algebra all the time. A lot of what an admin does is identify parts of a process that can be automated from existing data. Since very little of the data in Salesforce is numerical you'll rarely do traditional math.

I constantly recommend this book to people transitioning into CS from other careers because it explains why Boolean Algebra is so important to how systems work and is extremely entertaining. It also doesn't have a single line of code in the whole book. It's really just about the concepts that power code and how these concepts can be applied in any system.

With all of that said, the Salesforce ecosystem is so large that you don't have to be an admin. If you like teaching but want a raise there are tons of companies that hire Salesforce trainers. They are typically salesforce admins that really enjoy working with users over development. Get your cert, get some experience then find your niche.

Teaching CS is hard but I think the root of it is our ability to teach people how to think. Learning to program is easy compared to the problem of learning how to think algorithmically.

IMHO this is because a lot of CS courses start at a very high level with very abstract concepts, which might also be because they can't afford to start with the very basics of "how does a computer work" due to the limited time available.

On the other hand, I think CS should always start with a book like this one, which truly does start at the basics:

A large part of why beginners fail is because they expect too much of, and don't comprehend, how the machine works. I believe that once they see how this complexity is actually the result of a large number of very, very simple operations, they will have a better understanding of what it means to instruct the machine.

I still haven't read anything better than Code by Charles Petzold [1] and it's not even close.
