A couple of questions in class...
Net
- ...
- Is it true that you can get car insurance from GEICO at 15% of your current insurance?
- LOL!
- Why don't you ask Prolog?
(End of Net)
I was laughing too much to come up with an answer.... but here it is.
This would answer the question
GEICO <= Current * (1.0 - 0.15).
if the variables GEICO and Current were instanciated with the right values...
And you could define a couple of predicates to describe the offerings:
geico(....).
current(.....).
and then compile these and the query below will answer the question:
geico(GEICO),current(Current), GEICO <= Current * (1.0 - 0.15).
A more comprehensive approach is via a predicate/data base
- car_insurance('AAA', ....).
- car_insurance('Farmers', ....).
- car_insurance('GEICO', ....).
- ...
and writing a predicate/program that picks the minimum price. There is a Prolog
solution but it goes beyond the elementary techniques in the book and the first
two labs.... as far as I can see. I'll post a solution later.

We discussed Eliza, AI, and languages that are competing with LISP in the AI domain.
Jack Price found
[ eliza ]
a simplified Eliza running on a web page in the University of Birmingham, England.
It is written in Poplog. Poplog is a language that we don't have time to study. It is the
marriage of Pop and Prolog.
Pop
was a interpreted functional language "Pop" developed in Edinburgh (circa 1967),
Scotland by a man called Popplestone.
[ POP-2 ]
He claimed the name came from the run-time stack he used, however.
I have always like the look of it -- I have the manual in my office.... but I've never used it.
And it has never got very much press or following. However I have stolen some ideas from it
and put them in my own MATHS language.
We will talk about Prolog at the end of this course.

[ GCC-Moving-To-Use-C-Instead-of-C ]
An anonymous reader writes "CodeSourcery's Mark Mitchell wrote to the GCC
mailing list yesterday reporting that 'the GCC Steering Committee and the
FSF have
[ msg00705.html ]
approved the use of C++ in GCC itself. Of course, there's no
reason for us to use C++ features just because we can. The goal is a
better compiler for users, not a C++ code base for its own sake.' Still
undecided is what subset of C++ to use, as many contributors are experts
in C, but novices in C++; there is a call for a volunteer to develop the
C++ coding standards."

I've added a call to "srand" to initialize the random number generator
to a different seed each time you run xlisp, at the request of a user.
Note: In the 1980's C let you get away with almost contradictory
declarations. But this is no longer allowed so I had to fix

Last night in the lab I discovered that the machines in JBH359 have
a shiny new SWI Prolog installed on them. It has a neat GUI help
system..... And it understands more arrow keys.
You can run it with the command
/usr/bin/pl
(and so this is the default plthat you will normally get if
you don't use Q).
However they have moved the language closer to Quintus Prolog and
Gnu Prolog. The first consequence is that if you want a prdicate to
change as the program runs you must declare that it is dynamic
before you actually place any predicates in the data base. SOme
of my examples (4th.plg) didn't do this. So I've just editted them
and reuploaded them.
The other cosequence of the upgrade is that a rather usful predicate
called select has changed its definition. I use it mainly
to generate permutations:
perm([],[]).
perm(X,[Y|Z]):-select(X,Y,R),perm(R,Z).
This works by selecting each element Y out of list X leaving
the rest of the list in R. So select([1,2,3], Y, R) generates
these alternatives:
Table
(Close Table)
Now Quintus Prolog has a different definition with the parameters
X and Y are in a different order:
perm([],[]).
perm(X,[Y|Z]):-select(Y,X,R),perm(R,Z).
On the other hand they have permutation already defined so replacing
the two line definition of perm by
perm(X,Y):-permutation(X,Y).
is a quick fix.
By the way... the /usr/bin/pl isn't on jbh3-1 the SSH server:-(
I guess I'll have to add fixing this to my list of fun jobs for the summer.

The following cam in from Victor who took CS320 some years ago.
I also had a quick (maybe) question for you about Ruby. I'd like
to get a hold of a good Ruby compiler to install on a Linux
machine. I don't have Admin privileges though, so I'm hoping to
run it from my home directory. I need it for a program called Tioga
which uses Ruby to install and plots Stellar evolution data in
beautiful ways I haven't seen before using pdf and latex tools
working together with Ruby I think. I read on the web "37 things I
love about Ruby" and the programming language sounds too good to
be true lol. I never heard of a "very-high level language (VHLL)"
which it claims to be.
Does any body know a good Ruby compiler/interpreter for users
on a Linux system? Email me and I'll pass it on to Victor.

Fortress a big jump on Fortran
[ 0,7204,21124560%5E15321%5E%5Enbv%5E,00.html ]
Barbara Gengler JANUARY 30, 2007
REMEMBER Fortran? Sun Microsystems is developing a follow-up programming language that may drive high-performance computing in the future.
The prototype Fortress, released as open-source software, is intended to take the place of Fortran.
Sun also released a series of draft specifications of the language and published formal calculi and soundness proofs of several of the core language features.
This just in from the Assoc of Computing Machinary:
Sun Microsystems has announced that it will open-source its new Java
compiler, Javac, through a project known as the Kitchen Sink Language
(KSL), which will allow programmers to play around with the language in
hopes of obtaining data on which to base debates concerning the dynamic
language. Javac lead tech Peter von der Ahe says, "I see a lot of proposal
for enhancing the language and our team has to turn down most. So how can
we experiment?" KSL, a Sun incubator project created by Java creator and
Sun Fellow James Gosling, is a forum that will let programmers evaluate the
language "by using [it] on their own code," rather than reading abstract
specifications and proposals, according to von der Ahe. He understands the
potential for chaos that KSL could bring to the language, so he explains
that Sun must be "conservative" when evaluating features to implement. In a
Jan. 8 blog post, Gosling said, "I've never been real happy with debates
about language features. I'd much rather implement them and try them out."
Though some took this to mean that Gosling did not like any debate on the
subject, he clarified himself by explaining that he did not approve of
debate when it was separated from "experiment and data," and that KSL will
provide this type of scientific foundation for debating features.
