As I am building my simulator using createljs, I will need to have thousands of little circles ( 3 pixels diameter ).\nI can draw a circle on a shape graph, is this a recommended approach? or shall I use a bitmap?

\n\n

Any idea about the best way in terms of performance?

\n\n

Also, is it possible to set text antialias on or off?

I've been working through problems on 4Clojure today, and I ran into trouble on Problem 28, implementing flatten.

\n\n

There are a couple of definite problems with my code.

\n\n
(fn [coll]\n  ((fn flt [coll res]\n    (if (empty? coll)\n        res\n        (if (seq? (first coll))\n            (flt (into (first coll) (rest coll)) res)\n            (flt (rest coll) (cons (first coll) res))))) coll (empty coll)))\n
\n\n

I could use some pointers on how to think about a couple of problems.

  1. How do I make sure I'm not changing the order of the resulting list? cons and conj both add elements wherever it is most efficient to add elements (at the beginning for lists, at the end for vectors, etc), so I don't see how I'm supposed to have any control over this when working with a generic sequence.

    2. \n

  2. How do I handle nested sequences of different types? For instance, an input of '(1 2 [3 4]) will will output ([3 4] 2 1), while an input of [1 2 '(3 4)] will output (4 3 2 1)

    3. \n

  3. Am I even approaching this from the 'right' angle? Should I use a recursive inner function with an accumulator to do this, or am I missing something obvious?

It is possible to do it with additional script file and xargs, but I'm looking for way to do it in one line.
