Those would be of great interest to many of us. Please do.

Great job doing the transcript!

Hi all,
I have created the function that read a txt file. I have a very
little experience in clojure and I will be thankfull for any
correction and ideas.
This is source code:
(defn create-freader [filename]
(def f-reader (new java.io.FileReader filename))
f-reader)
(defn create-br

It's from github, yes. The version number is actually a bit meaningless:
the 'master' branch on github has been on 1.1.0-alpha-SNAPSHOT ever
since 1.

For the record: see (doc line-seq)
But here some suggestions, since learning clojure is your main
Just an FYI, you can also use the builtin slurp function, which will
return the contents of a given file.
(slurp "file.txt")

Hi,
I've written a genetic programming framework in Clojure, it might
be of interest if you're looking for some inspiration:
http://bitbucket.org/svdm/clojuregp/s
I'm trying to make a decision in a parser library between using
regular maps as states (containing a sequence of remaining tokens, as
well as other info) vs. using metadata maps attached to the sequence
of remaining tokens. In other words:
{:remainder [\r \e \m], :index 3, :line 5, :column 2}
Hi,
I read the related story on InfoQ and found it an extremely
interesting and motivating read, Clojure being applied in such an
interesting field as machine learning!
There is something in the article I'd like to understand better, so
i'm just asking here on the group:

There is a slight performance penalty over a normal function call. I
think the dispatching takes one function call, a hash lookup, and a
Hrm - I couldn't clone any of the clojure builds as they wer'nt listed, and
I see theres no agent that'll build maven2 so my builds just stuck in the

Took a shot at implementing PI in Clojure using a reasonably fast
algorithm.
So why is it so slow ? Is BigDecimal just that bad ? Would fixed point
arithmetic be better using BigInteger ?
