cnbbooks / lfe-sicp Goto Github PK

Hi Duncan. This is Nelson from the mailing list. I'm going over the book and you talk about the "true atom" without giving a discussion on what an atom is. A search through the repo only talks about atoms in this section.

make deps works however I am unable to make setup and therefore the local copy of the Gitbook. What am I missing?

Core i3 on Netrunner which is based off of Arch Linux.

Output:

sudo make setup

This is a ticket for accepting feedback to the LFE preface (we're still keeping the prefaces to the 1st and 2nd edition).

• In the "Introduction " section, change "below" to "the following sections", e.g., "the mathematical and computational history leading to Lisp has been greatly simplified below" and "the four famous mathematicians listed below"
• In the Peano section, show the example of recursion from his axioms
• In the Russell section, show examples he gives for propositional functions with and without bound variables (from the Principia)
• 6.4 first sentence "The ups-and-downs of Lisp since it's inception in 1958" should read its no apostrophe.
• Update the content in the book with changes made in the blog posts

Hello,

I'm reading the LFE SICP book compiled with the mdbook binary and the LaTeX formulas are displayed as a source, not the compiled LaTeX output.

Thanks for all the great work on LFE

Towards the end there is a sentence about Scheme and Chapter 5.

"The implementation of Scheme we shall consider in chapter 5 does not share this defect. It will execute an iterative process in constant space, even if the iterative process is described by a recursive function."

If you stick with the current chapter numbering then I believe the chapter would be 15. The part about implementation of scheme will have to be looked at again after the completion of the book since it is unknown whether there will be an implementation of scheme.

In the book you start with chapter 10 and is non traditional. For example, in 10.2.3 Evaluating Combinations you mention chapter 11 which I presume is Chapter 1 for SICP. This is confusing. Is it possible to stick to the original SICP chapters and move 1-9 to an introduction/preface chapter?

In the exercise funcall is mentioned once before but never with the code #'+/2

(defun a-plus-abs-b (a b)
  (funcall (if (> b 0)
                   #'+/2
                   #'-/2)
               a b)))

So I'm assuming that # is some type of way of referencing the quoted function.
#

What exactly does the # do? I tried looking through the reference but it's hard to search for just #

I would like to start contributing to this repo. I am currently working as a software engineer, and I have computer science background. Is there any plan on how to contribute to the document?
any guidelines or plans?

maybe I'm missing an obvious alternative form, but in my solution for the exercise you need the "head" from the unpacking in the second case in the pattern match (which is discarded in the template).:

(defun subsets
  (('()) '(()))
  (((cons head tail))
    (let ((rest (subsets tail)))
      (++ rest (lists:map
                      (lambda (r) (cons head r))
                      rest)))))

Also, I think that using ++ instead of append might be useful to avoid loading that function.

(= a b)
should be
(== a b)

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

(cond ((= a 4) 6)
((= b 4) (+ 6 7 a))
(else 25))

should be

(cond ((== a 4) 6)
((== b 4) (+ 6 7 a))
(else 25))

Gitbook has changed its services and some of our stuff no longer builds. It would be nice to use some tooling that doesn't depend upon a service going away ... and I'd love to not have to use Ruby.

Ideally, whatever solution we use going forward should satisfy these conditions:

• allow us to continue using the content we've created in markdown with no (or very few changes)
• be usable without having to install tons of dependencies on our systems (e.g., support docker usage)
• not be part of some pay-for-service that could be taken away at any point in time
• support generating and viewing books locally
  a
  One option that is used to generate the copious markdown-based books in the Rust programming language community is this one:
• https://github.com/rust-lang/mdBook

I'll see if it meets our other criteria ...a
