using more then one thread is no silver bullet.
What would you do if you have to count to 1.
Would you just start counting or would go and hire 2 more people
explain them what to do and then count together?
In this case you would just start counting because you know that you
will be faster b

Thats what I came up with this.
(defn getpairs [[key coll]] ;; split the key form the data (http://

(map (fn [x] [key x]) coll)) ;;put the key in front of every

(defn d-map [& colls]
(mapcat getpairs colls)) ;;mapcat

Good and clear in this case.

I think that would be nice if there were three functions.

I ask myself that from time to time. I tend to use (partial + 2)
because I think its easier to read.
The (+ 2) bit is intressting. That would be automatic currying, you
get that in other languages. It is not possible in Clojure becaus
there is no limit to how many args a clojure function can take.

I'm started working on PAIP and doing the examples in Clojure. I

(iterate inc 1) is not the function vector is
what you do is call vector with the first of primes and (iterate inc

so the first things map does is

meaning the first is the index number the second is the corresponding

"clojure sees 'signal' as 2 collections" thats wrong signals is one
collection with two items. These happen to be collection but only the
function that gets called by map carres what it gets.
How can this
(map #(map reduce + %) signal)
work? (map ) does take 1 function and some collections
It would be fantastic if the talkes would be record. We have seen the
effects a couple of videos of rich had on the world and how many

The Clojure compiler is still in Java. I think befor someone does a
big project with the compiler it should be translated to clojure.

Clojure runnes manly on the JVM. Oracle ownes (or has the patents) why

As far as Dalvik goes. Why should Clojure care the lawsuit is about
implementation details (as far as I understand) in the VM the basic
working will be the same.
Befor starting a real effort
Good Question, I was wondering that too. Interfaces have some
problems. Protocol solve some of the Problems and Traits solve some
but the do not solve the same. Would be interesting to hear how
Protocols solves those problem, why the don't are problems or why the
don't need to be solved in Clojure

Hallo all,
Haveing the option of something like that would be nice but atm I
think we should not focus on that. Clojure is still a young language
and there is enought to do.
We should not confuse people with diffrent dialects of clojure
allready.
