Re: Spread work onto multiple threads (in pure Clojure)

I haven't read the entire thread carefully, but have you considered the "work" library as a potential fit for what you are trying to do? Example from the github link: user> (require '[work.core :as work]) user> (work/map-work client/get ["http://clojure.org"; "h

Re: Lazily read XML larger than memory: my take at parser API

Interestingly, I had planned on using Jackson, but found that because my JSON data in fact was not always well-formed and needed minor cleaning steps (e.g. double newline without interleave commas between JSON chunks), I needed to create better chunks of well-formed JSON first in a streaming sort o
