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.

Credibility is everything. People are busy, so they heavily use personal trust to inform their decisions. You must become credible.
Credibility starts with technical competence, rather than shared aesthetics. Do not start contributing by engaging in design debates.

	# bash function
	defcomp () {
	local name="$1" && shift
	local functionName="$( echo "${name}_completion" \| tr - _ )"
	source <(cat <<EOM
	$functionName () {
	local cur
	_get_comp_words_by_ref -n =: cur
	COMPREPLY=( \$(compgen -W "\$( $@ )" -- "\$cur") )
	}

	(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
