special, it seems like you might just as well map a column adjustment
function over the result set yourself? It feels very clunky.
The JDBC library requires us to treat these columns special. If we

Hey all,
Spent most of yesterday trying to draw a chessboard on a paintable
canvas, however I'm stuck after drawing the lines of the grid...I mean
the grid is there but its all one colour (the background colour of the
panel)! The fn that draws the lines is simply this:

You can try using the multi-input version of map to knit your data
together with some other, potentially infinite, sequence:
(map vector items (cycle [black white]))
It returns something like this:
([item1 black] [item2 white] [item3 black] [item4 white])
Then you can use doseq over that,

Yeah, sorry Dimitri, I wasn't very clear :-) I meant that if you were going
to do it recursively you would be using the first element of the seq, and
you would be passing the (rest) of the seq to the subsequent recursive
call. Very elegant solution!

Hi,
I've been digging into the sources of Clojure and found frequencies.
There's the transient function and I thought I'd use it with a map and
conj. Why does this fail?
user= (conj {} {:y 1})
{:y 1}
user= (conj (transient {}) {:y 1})
ClassCastException [trace missing]
I ran into the issue
you must use conj! instead of conj.

A transient map can't be a persistent map at the same time. You
need to use the transient version of conj, called conj! to conjoin

I am trying to remove every occurrence of a given element from a vector. I
can use (filter #(== % a) v) where 'a' is the value to be removed and 'v'
is the vector, but this returns 'a' and 'a' is the value i want to remove.
So, how can i do this? I tried replacing 'filter' with 'remove' but it
Hi,
Does this work for you?
(remove #{:a} [:a :b :a :c :d :e])
Also, if you have a list of items you can have all of them in the same
set/predicate like so -
(remove #{:a :z :x} [:a :b :a :c :d :e :z :b :d :e :x :z])
Hope this helps.

To clarify Baishampayan's code, hash-sets in Clojure are functions:
= (#{1} 1)
1
= (#{1} 2)
nil
Nil and false in Clojure are the same thing,
So Baishampayan's example:
(remove #{:a :z :x} [:a :b :a :c :d :e :z :b :d :e :x :z])
#{:a :z : x} will return nil if the value is not in the vector,

The group hasn't met in a long time, but we were actually talking
about some kind of a relaunch last week. We were hoping some Clojure
interest had increased in the DFW area since we tried last time.
Anyone else in the DFW area interested in getting together?

Hi,
It seems reduce-kv doesn't reduce a sorted-map in the correct order.
Example -
user (def *sm (into (sorted-map) {:aa 1 :zz 2 :bb 3 :yy 4 :cc 5 :xx 6}))
;= #'user/*sm
user *sm
;= {:aa 1, :bb 3, :cc 5, :xx 6, :yy 4, :zz 2}
;; plain reduce
user (reduce (fn [ret e] (conj ret e)) [] *sm)
;=

No, there is no language-level distinction between pure functions and
functions which perform side effects. In practice, it is a good idea to
keep them separate.
