Thank you Josh for your answer.
I have read the sources of datalog, however, literal.clj and the ideas
of the query language behind it is unknown for me, thus I can not
understand it quite well. The same thing happens when I saw magic.clj,
in which file I saw "magic transformation".
I ran the ex

I was having the same problem as Jim and ended up just getting SLIME
working manually.
I wanted to get things set up like Vagif Verdi mentioned above so that
I can start the REPL from my own script and then connect to it from
emacs using slime-connect.
The good news is that I am using SLIME now
Terrance, you could do something like this (loose on the syntax):
(def final-foo
(let [tmpString (. javax.swing.JOptionPane showInputDialog "What is your
foobar?")]
(. Double parseDouble tmpString)))
Look at this comment for one example of a function written both ways:
http://lojic.com/blog
For instance, in Java ...
tmpString = JOptionPane.showInputDialog("What is your foobar?");
finalFoo = Double.parseDouble(tmpString);
instead of ...
finalFoo = Double.parseDouble(JOptionPane.showInputDialog("What is
your foobar?"));
I translate this into Clojure as something like ...
(def fin
It also should be interesting to create a bridge between clojure and
Maxima.
Transforming clojure expression into maxima expression,
for example the Maxima list ((mlist) 1 2 3 4)) is the clojure list
'(1 2 3 4)

Could you post an example? It'd be easier to comment on it.

Commonly, I break down complex lines of code into several easy to
follow simple lines of code. This results in many temp variables that
are not intended to be used anywhere else in the code. Sometimes I see

Ah Matlab... reminds me of school. Culturally, it's the new FORTRAN.
I agree, a good Matlab book is hard to find. I'd look into a couple
things:
1. Find an engineering book on the problem you're studying. They all
include "how to do this in Matlab" nowadays.
2. Google "atlas linear algebra

I don't see that anyone has answered your question. I too like Matlab
and I have also used
Mathematica and see the value in both. Matlab though is the superior
platform for numerical
analysis and computation (in my opinion). I think it offers better
features for extensibility

Two things: git maintains this record automatically and much more
thoroughly
I've been playing with matlab, and I'm liking it... the built in
documentation on the language is actually excellent, and the language
itself is pretty clean if you're used to java/c/algol type languages.
I like especially the built in syntax for matrix and tensor
operations, and the fact that ope

Two more questions:
3. In datalog.database , it is required that every tuple must has
exactly same field as in database define, is that possible to just
define some necessary fields, and tuples appended can have additional
optional fields?
4. What is a magic transformation? I googled the term, but

I am trying to use datalog now, have the following questions:
1. How about the memory consumption of datalog?
2. There are examples of datalog, but can I find more detailed
document about the query language?
