The notion that “thinking about computing is one of the most exciting things the human mind can do” sets both The Little Schemer (formerly known as The Little LISPer) and its new companion volume, The Seasoned Schemer, apart from other books on LISP. The authors' enthusiasm for their subject is compelling as they present abstract concepts in a humorous and easy-to-grasp fa ...more

The quotation in my version from chapter 7 about fun? is

What is (fun? rel)
where
rel is ((d 4) (b 0) (b 9) (e 5) (g 4))

#t because (firsts rel) is a set
---See chapter 3

So it doesn't say that '(fun? somelist) is #t if the first item in the list is a set' but says that '(fun? somelist) is #t if (firsts somelist) is a set'. (firsts somelist) is the first item of each of the tuples contained by somelist.(less)

Wow! What a journey!

This is a really neat little book about recursion, written in Scheme. It's written completely in a Q&A format, with some funny banter and non-sequitur thrown in. What this format does is it encourages you to think about the questions it asks before reading about their answers. Sometimes, the questions are impossible to answer with the knowledge you have, but usually you can kind of tell when those are coming (the beginnings of chapters) and not spend too much time thinking ab

Reading this book, I couldn't stop thinking about how much I would have loved and treasured it when I first started getting interested in programming in middle school. It's not necessarily written for children, and I'm not saying it's not a fun/stimulating read for an adult, but that's the perspective I want to review it from.

Around that time I spent hundreds of hours playing around with QBasic, and I remember being so curious how it "worked"... Not from a registers and pointers perspective, but

Just finished the book, good read, unusual book. The leading topic is Recursion. The book is written in a question-answer style that needs getting used to but is well designed an kept me interested. I found the style a bit tiresome at the beginning, because the matter starts off quite easy and the presentation does not really allow you to skip lots of stuff completely, as you will never know what you have missed. Its really designed to be read cover to cover.

hrm. The Little Schemer seems like a great book for a 12 year old grad student; that is to say, the style and the difficulty of the concepts in the book are somewhat at odds.

It starts out in a cutesy style, with back and forth questions and answers, whimsical instructions to make yourself a pb&j sandwich or eat a slice of cake... but about half way through the conceptual difficulty ramps up considerably. It ends up covering currying, the halting problem, multi-argument continuation passing styl

The Little Schemer is an excellent introduction to computer science concepts as they relate to the Scheme/Lisp way of programming. It is heavily focused on recursion as a core, fundamental part of computer programs in a way that many other computer science books are not. Functional programming concepts are covered, but this is not a strictly functional book. Concepts are presented naturally and their importance emerges from the examples. The book never stops to say "Okay, here comes an importan ...more

A pet peeve of mine is how the quality of books on technical subjects (computers, specifically) has decline so radically since (*kaff*) I stopped writing them. Seriously, a famous book on Rails—perhaps considered the canonical book, it's so popular—epitomizes the awfulness of it all. How, you ask? Well, I went through said book and counted the number of things you had to learn in the first chapter and came up with a total 17!

17 things, Bob.

The Little Schemer is geared toward luring you into first the syntax, then the concepts behind Scheme, recursion, and functional programming. While probably of most interest to programmers or the mathematically inclined, the book claims to have been based off lecture notes for liberal arts students.

The book has a very interesting dialog mechanism for teaching. After the introduction, there is little to nothing in the way of paragraphs of information. Instead, it is more of a lightweight Q&A whic

A really fun read that reinforced my understanding of recursion and some FP concepts. Intermediate Lispers or people with a good grasp of basic functional programming can safely jump forward at least a few chapters (though you'll miss some function definitions used later on).

I was unsure about this book (it seemed a little basic) until I reached the section on continuations. From that point on, I was pretty amazed by the code. You'll find Y-combinators and metacircular interpreters explained in

Thoroughly didactic, and a considerable brain twister, this book and its exercises did a great deal for my programming skills. In particular, it furnishes stepping stones of a craft to decompose computing problems into recursive solutions.

I found the last two chapters fiercely difficult, and cannot say that I truly retained them. However, I greatly enjoyed the opportunity to glimpse deeper mathematical aspects of the lambda calculus.

For anyone wishing to learn a lisp-like, I thorough recommend t

This book is a series of questions geared towards helping the the reader learn the material by figuring out the answers.

I think this book is best studied, rather than read, in short bites, taking plenty of time to understand each concept. I'm finding I can get through 2 or 3 pages per sitting. The book builds on prior concepts to aid in understanding new concepts.

So far, its taught me more about LISP than any other book, white paper or man page I've read.

This is one of those books that changed me. By following a set of "commandments" presented in this book I learned to think clearly about functional programming, recursion and the Y-combinator. It also helped me ease into currying and other combinators like the S, K and I.

After you read this book, you should read "To Mock a Mockingbird" and also start learning Haskell.

The power of types in Haskell will one day compel you to understand the language of Category theory in mathematics, and after you

The Little Schemer is a classic computer science text and there are very good reasons for it: it's poignant, entertaining and teaches you more about Lisp than many of the bigger books around. This is not a complete guide to Scheme as a programming language, it's a book about concepts. Highly recommended!

Easily one of the solid and neat introductory books to LISP. Used Racket lang with IDE as DrRacket to code and learn alongside this book. What is K&R for C Programmers, this book series by Daniel P Friedman, could be for people wanting to learn LISP. Going through this book allows people to think about programming in a new thinking way. ...more

Teaching entirely novel things is hard. Teaching a person to appreciate the need for something before that something has been given a name is even harder. It's not done in undergraduate Java-school computer science. It's vital that we convey the jargon. Polymorphism, encapsulation and inheritance are definitions we're taught because we know that HR people who interview us will ask these questions. Clearly a strong indicator of computer programming acumen is the ability to spout the jargon, right ...more

Reader response, freshly finished: Unsure how I feel about this book.

I really love the didactic style. I found it easy to keep pace. It taught Scheme in a really digestible way .... until the end.

At least, I think it stopped being that digestible by the end. As someone who knows Scheme and understands the concepts (reasonably well), I found slowing down to be difficult, and I also didn't feel the book convinced me why I'd go through the contortions the latter half of the book made me go through.

It's difficult to express how interesting this book is. The format is a set of questions and answers, which is initially quite an odd read. However as the book unfolds you begin not only to appreciate the book's quirky style but also the power of the lessons contained within the book. It is a testament to the power of the material that by the last chapter you have sculpted a scheme interpreter from the bones of some really simple functions at the start of the book. In fact what this book demonst ...more

I really wanted to like this book, alas it was not for me.

I was looking for a deep, philosophical computer science book using scheme. The book makes seems to have two assumptions:

1. You already are somewhat familiar with scheme.

2. You do not know what recursion is.

Of course, if you have any familiarity with scheme then you are likely quite familiar with recursion. I already knew scheme but can imagine someone coming to it with no background being a bit confused when terms are given with no expl

I expected to enjoy this a lot more than I did. If you're looking to learn Scheme but don't have any experience with it whatsoever—and especially if you don't have any experience programming at all—this book will be near worthless to you. If you already have some experience but would like to flesh it out a bit more, like I did, its gimmicks will get on your nerves really quickly.
The Little Schemer spends a tremendous amount of time focussing on trivialities while skipping over far too many funda

I've been super curious about Lisp since Hackers & Painters . Then I found this book. It is a spoonful (yes in the sense of Food) of Scheme, a flavor of Lisp.

First and last impression: Lisp IS abstract. People are right. It can be practical but, this is purely abstract. It does not feel like a programming language, not like any of the languages I know, but some mathematical syntaxes. It defines primitive functions then builds more complicated ones on top of them using recursions. Recursions aft

What a wonderful little book! It's surprising how much is learned by figuring things out on your own from questions and answers and not reading lengthy explanations as in other books. I think that helps to engage the reader and adds more interactivity. I wonder if more books can benefit from such a form...

Little Schemer is also amazing in that it starts extremely easy, but the last 2 chapters are devoted to the Y combinator and a scheme interpreter which are not easy at all! And along the way it

At first I was expecting a book to brush up my functional programming skills. But after I finished the first seven chapters in around 4 hours, I realized it was actually a book to teach basics of programming, in a fun way of course. However, as it continues on harder topics like continuation and Y combinator, things are getting more interesting. I really didn’t feel like I was actually LEARNING something, instead I simply picked up essential ideas during those set-up communications. It was reall ...more

Great great GREAT read that teaches you how to think recursively. I typically don't give technical books 5 stars, because as as helpful as they are, they usually aren't game-changing. While I understood what recursion is and how it works, I always struggled writing recursive code...until now. The book is written entirely in a question and answer format, which I found disconcerting at first, but turned out to be immensely effective. The book centers around the language LISP, but, even if you will ...more

Update of the absolute classic "The Little Lisper". One of the first books any budding programmer should read.

It's not a guide to writing commercial programs. Rather it's a guide to write programs well. The basic concepts and constraints within the functional language and it's simple syntax forces the budding programmer into a mindset for programming excellence in the future.

That is not to say many programs have not been written in Scheme. This a simple introduction of the basics of programming,

Truly a spiritual experience. I felt like I have seen into the eye of computation, and it stared back at me. Slowly it whispered ... 'λ'. It got louder. 'λ ... λ ... λ'. Nothing made sense any more. I saw complexities collapsing into simplicities and simplicities expanding back into complexities. Everything became a sum, a product, an evaluation. Add, minus, car, cdr.

When I awoke from this dream I found my laptop left on with a copy of this book next to it. Was pretty cool I guess.
