Quotes from Code

“Code is not like other how-computers-work books. It doesn't have big color illustrations of disk drives with arrows showing how the data sweeps into the computer. Code has no drawings of trains carrying a cargo of zeros and ones. Metaphors and similes are wonderful literary devices but they do nothing but obscure the beauty of technology.”
― quote from Code

“In 1948, while working for Bell Telephone Laboratories, he published a paper in the Bell System Technical Journal entitled "A Mathematical Theory of Communication" that not only introduced the word bit in print but established a field of study today known as information theory. Information theory is concerned with transmitting digital information in the presence of noise (which usually prevents all the information from getting through) and how to compensate for that. In 1949, he wrote the first article about programming a computer to play chess, and in 1952 he designed a mechanical mouse controlled by relays that could learn its way around a maze. Shannon was also well known at Bell Labs for riding a unicycle and juggling simultaneously.”

“We could just as reasonably base our number system on eight (if we were cartoon characters) or four (if we were lobsters) or even two (if we were dolphins).”
― quote from Code

“Some people believe that Moore’s Law will continue to be accurate until about 2015.”
― quote from Code

“Programming in machine code is like eating with a toothpick.”
― quote from Code

“I said early on in this chapter that we would need 144 relays for our adding machine. Here’s how I figured that out: Each”
― quote from Code

“Today’s computers use transistors. When used in computers, transistors basically function the same way relays do, but (as we’ll see) they’re much faster and much smaller and much quieter and use much less power and are much cheaper. Building an 8-Bit Adder still requires 144 transistors (more if you replace the ripple carry with a look-ahead carry), but the circuit is microscopic. Chapter 13. But What About Subtraction? After you’ve convinced yourself that relays can indeed be wired together to add binary numbers, you might ask, “But what about subtraction?” Rest assured that you’re not making a nuisance of yourself by asking questions like this; you’re actually being quite perceptive. Addition and subtraction complement each other in some ways, but the mechanics of the two operations are different. An addition marches consistently from the rightmost column of digits to the leftmost column. Each carry from one column is added to the next column. We don’t carry in subtraction, however; we borrow, and that involves an intrinsically different mechanism—a messy back-and-forth kind of thing. For example, let’s look at a typical borrow-laden subtraction”

“Bits also play a part in logic, that strange blend of philosophy and mathematics for which a primary goal is to determine whether certain statements are true or false. True”
― quote from Code

“In the same way that Morse code reduces written language to dots and dashes, the spoken version of the code reduces speech to just two vowel sounds. The key word here is two. Two types of blinks, two vowel sounds, two different anything, really, can with suitable combinations convey all types of information.”
― quote from Code

“Just as Morse code provides a good introduction to the nature of codes, the telegraph provides a good introduction to the hardware of the computer.”
― quote from Code

“You’re twelve years old. One horrible day your best friend’s family moves to another town. You speak to your friend on the telephone now and then, but telephone conversations just aren’t the same as those late-night sessions with the flashlights blinking out Morse code. Your second-best friend, who lives in the house next door to yours, eventually becomes your new best friend. It’s time to teach your new best friend some Morse code and get the late-night flashlights blinking again.”
― quote from Code

“a digital design engineer, you would spend long hours going through the TTL Data Book familiarizing yourself with the types of TTL chips that were available. Once you knew all your tools, you could actually build the computer I showed in Chapter 17 out of TTL chips. Wiring the chips together is a lot easier than wiring individual transistors”
― quote from Code

“The flip side of this is that any information that can be reduced to a choice among two or more possibilities can be expressed using bits. Needless”
― quote from Code

Popular quotes

“Plan every battle as if you will inevitably retreat, but fight every battle like there is no backing down.”
― Brandon Sanderson, quote from Oathbringer

“How come someone always saves the people who try to kill themselves and then makes them tell everyone how sorry they are for ruining their evening? I keep feeling like everyone wants me to apologize for something. but I'm not going to. I don't have anything to apologize for. They're the ones who screwed everything up. Not me.

I didn't ask to be saved.”
― Michael Thomas Ford, quote from Suicide Notes

“The situation collapsed completely at dinner one September evening. Perhaps it was the full moon that drove me to madness, or the gnawing, relentless emptiness of my heart. Whatever the trigger, the powder had been well packed, and my explosion, though shocking, was not altogether unexpected.”
― Catherine Gilbert Murdock, quote from Princess Ben

“The two boys stood and looked at each other. There was no amusement and no scorn in Attean's eyes. How very strange, Matt thought. After all the brave deeds he had dreamed of doing to win this boy's respect, he had gained it at last by doing nothing, just by staying here and refusing to leave.”
― Elizabeth George Speare, quote from The Sign of the Beaver

“I’m bored of this. I want to hear about you. Favorite color. Go.”
I laugh. “Green.”
“I’m green!”
“Fuck yeah you are.”
“Why are you laughing? Isn’t this what friends do?”
“Interrogate each other?”
“What? Uh, sure. I don’t know what that means. But yes.”
― Hannah Moskowitz, quote from Teeth

About BookQuoters

BookQuoters is a community of passionate readers who enjoy sharing the most meaningful, memorable and interesting quotes from great books. As the world communicates more and more via texts, memes and sound bytes, short but profound quotes from books have become more relevant and important. For some of us a quote becomes a mantra, a goal or a philosophy by which we live. For all of us, quotes are a great way to remember a book and to carry with us the author’s best ideas.

We thoughtfully gather quotes from our favorite books, both classic and current, and choose the ones that are most thought-provoking. Each quote represents a book that is interesting, well written and has potential to enhance the reader’s life. We also accept submissions from our visitors and will select the quotes we feel are most appealing to the BookQuoters community.

Founded in 2023, BookQuoters has quickly become a large and vibrant community of people who share an affinity for books. Books are seen by some as a throwback to a previous world; conversely, gleaning the main ideas of a book via a quote or a quick summary is typical of the Information Age but is a habit disdained by some diehard readers. We feel that we have the best of both worlds at BookQuoters; we read books cover-to-cover but offer you some of the highlights. We hope you’ll join us.
