I just remembered that people always ask me what version of clojure
I'm using, 1.3.0-master-SNAPSHOT.

I'm working on problem 66 at project euler and this is my solution so
far. It calculates the minimum "x"s just fine but takes almost a
minute when I turn limit up to 20. It's not going to solve the
problem fast enough but what I find strange it that if I set the limit
to 20 then nothing happens f

I thought it was strange that the first iteration ran so fast, so I

why the first iteration before was so fast, the JIT is supposed to
make it faster isn't it?

I've been benchmarking java and clojure programs and wanted to make

I'm shooting for 60 fps but I can barely get 10 when the box is
falling and when it lands on the ground an

I have this function
(defn floor
^int [^float x] x)
and (floor 1.5) returns 1.5 which confuses me as to how type hints
work, I was expecting the result to be truncated or for the program to
spit out some exception about expecting an int and getting a float.

This code,
(defprotocol Matrix
(matrix-get [this c r]))
(deftype Matrix2D [data height width]
Matrix
(matrix-get [this r c] 1))
Gives me this error

What is wrong with my code(bottom of post)? I keep getting this

Math/abs won't accept ratios, so I assumed the Java Math functions
only took base number types but all the other methods I tried accept
ratios just fine.

Leiningen was working just fine and I was perfectly happy, and one day
I decided I'd like to wrap my head around maven. The instructions for
using the maven clojure plugin are very concise and easy to follow,
but they just don't seem to work for me. My pom.xml is at the bottom

I'm not sure what to do here, my program hangs at the following

A slight tangent, is there anyway to represent exact square roots?
I'd like to have an exact closed form fibonacci function.

Problem 14 on project Euler is to find the number under 1,000,000 that
is the start of the longest Collatz sequence. My solution is below,
basically it uses a hash map to cache the lengths of collatz
sequences. But when I get to 113383 the collatz function just bounces
between the numbers 1, 2, a

Is this still a problem if you compile everything ahead of time? I
noticed that if I make a jar with leiningen my clj files are included
in the jar but I assumed that it was just part of some dogma that I
should share my source code.
Also, I asked a similar question where I was concerned about th

that mobile devices have but as I understand it the version of .Net on
the Xbox is a compact ver
I seem to be talking to myself but I've been told that if I find a
solution to a problem I should share it. I understand that deftype,
defprotocol, and defrecord are pretty volatile in development and my
eclipse plugin is simply using an old version of clojure.

If it's of interest to anyone this isn't a problem for me outside of
Eclipse.
