I keep planning on writing a post about contributing to OSS effectively, but I'm starting to doubt I ever will. So here's some tweets.

1. Credibility is everything. People are busy, so they heavily use personal trust to inform their decisions. You must become credible.

2. Credibility starts with technical competence, rather than shared aesthetics. Do not start contributing by engaging in design debates.

;; Based on a queue polling function from Chas Emerick's bandalore:
;;     https://github.com/cemerick/bandalore/blob/master/src/main/clojure/cemerick/bandalore.clj#L124

(defn wait-for
 "Invoke predicate every interval (default 10) seconds until it returns true,
  or timeout (default 150) seconds have elapsed. E.g.:

      (wait-for #(< (rand) 0.2) :interval 1 :timeout 10)

  Returns nil if the timeout elapses before the predicate becomes true, otherwise
