Created June 28, 2013 22:15
I indendet to see how to use fold to utilize pralell processing just to see that its prallel without the use of fold and pmap :/
(ns reducers.core
;(:require [clojure.core.reducers :as r])
)
(def N (iterate inc 0))
(def finish 6e6)
; this is just for testing if a random map function will stop the parelleltiy

Hi.

Though this isn't an Adcloud Event, we're mailing you because it's the same workshop we held last month at Adcloud. (Previously, we didn't have space for all the interested people.)

So if you are still interested, we will repeat an (improved) workshop this Thursday at the Cologne Clojure User Group.

Feel free to join us:

"Like incanter.core/head but returning the tail."

Some example code to answer the question of when to move results into a let.
;; using a let to store intermediat results
(defn recommendations [scores user]
(let [user-row (.viewRow (:matrix scores)
(get (:row-mapping scores)

sorted-by-score (sort-by #(get % 1)
(non-zero user-row))]

{:item item, :score score})
