Jepsen[1] is the killer app that's leading me to learn more about
the Clojure and Go ecosystems.
I mostly write Python by day but since Jepsen revealed consistency
problems in etcd[2], I've had to learn more Clojure/leiningen to see
if the ?quorum=true option fixed them.
What I've learned so far is that Clojure's error reporting sucks unless
you use something like Cider[3] and that etcd till fails to pass Jepsen
with ?quorum=true
