* Performance improvements include the use of epoll()/kqueue()
instead of select() for the Racket thread scheduler, cross-module
inlining of small functions, and the use of SSE instead of x87 for
JIT-compiled floating-point operations on platforms where SSE is

Hi,

here's a web spider program I made for guile, the s48 version might
be a bit buggy. It uses sockets, posix and posix-files only :

Hello,

I have this problem :

Utopia's tax accountants always use programs that compute income taxes
even though the tax rate is a solid, never-changing 15%. Define the
program tax, which determines the tax on the gross pay.

Also define netpay. The program determines the net pay of an employee

We are pleased to announce GNU Guile release 2.0.5. This release fixes
the binary interface information (SONAME) of libguile, which was
incorrect in 2.0.4. It does not contain other changes.

Please be sure to upgrade to 2.0.5 if you already installed 2.0.4.
We apologize for the inconvenience.

We are pleased to announce GNU Guile release 2.0.4, the next maintenance
release for the 2.0.x stable series.

The Guile web page is located at [link] .

Guile is an implementation of the Scheme programming language, with
support for many SRFIs, packaged for use in a wide variety of

Hello.

I skimmed R5RS, and found there was no `s-expression' or `form.'
Instead there were `data/datum' and `expression.'

I found a sentence:

And I found an example:

Which word (data or datum) is better to represent what is called an
`s-expression' traditionally?

Thank you.

Hello

One of the first exercises I have to make a Faharenheit -> Celcius
converter.

The formula is Celcius = (Fahrenheit - 32) / 1.8

So I did this :

def (Fahrenheit to Celcius)
/( - (F 32)+1) /( 8 10)

But I see this message :

<unsaved editor>:2:3: /: expected a function call, but there is no open

Hello,

Are the answers to the book "Structure and Interpretation of Computer
Programs" somewhere on the net.

I try to selfstudy LISP and it helps if I can see if the answers I give
are correct.

Hi,

this was my first guile related project.
Original (2003) homepage is here (I lost the password) :
[link]

I'm improving it after selling it by adding space levels, which is doable in scheme
and a few startup files (for graphics). Guile 1.6 is recommended for it for now!

Hi,

I've made the Comprehensive Scheme Archive Network (from CPAN) a reality.
It is a simple file fetcher client-server system written in scsh and thus
can also be used as an actor or agent system. You can implement
scheme CGI scripts for making e.g. a web interface for it.

It's in savannah's sunterlib git repository :

Hello.

I have just read Chapter 5 of this book. I cannot understand one
thing.

Question:
I think `eqlist?' is horrible, because I can easily write `equal?'
without this.
It is very straightforward. See, [link]
Why `eqlist?' is needed?

Thank you.

In the opening paragraphs of this paper, there's a tantalizing set of
sentences:

"The development of the compiler is described in detail in an extended
tutorial. Supporting material for the tutorial such as an automated
testing facility coupled with a comprehensive test suite are provided
with the tutorial."

This post is the third post in a series on computing with natural language data sets. For the first two posts, see the relevant section of our main content page. A Childish Bit of Fun In this post, we focus … Continue reading →

The Super Bowl is the championship game of the American league of professional football teams — and an annual cultural event. The first Super Bowl, won by the Green Bay Packers under head coach Vince Lombardi, was in 1967, and wasn’t even called “Super Bowl” at the time; the name didn’t attach to the game until Super Bowl III, when Joe Namath of the New York Jets guaranteed a victory. Roman numerals have been used to designate the Super Bowl ever since. The game this year, between the Boston Patriots and New York Giants, is Super Bowl XLVI; you can solve today’s exercise while you watch the game on Sunday evening.

John D. Cook turned the wacky roman numerals of the Super Bowl into an exercise at his blog; he was inspired by an advertisement for Super Bowl XLVI on a pizza box. Cook asked his readers to compute how many numbers can be expressed as roman numerals without duplicating any of the symbols I, V, X, L, C, D or M.

Your task is to compute the number of roman numerals that have no duplicate characters. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.

This post assumes familiarity with some basic concepts in abstract algebra, specifically the terminology of field extensions, and the classical results in Galois theory and group theory. The fundamental theorem of algebra has quite a few number of proofs (enough … Continue reading →
