If you care about default num behavior in #clojure read this and give feedback. Pls read rich's post on overflow vs safety. (here, via @wmacgyver) -- So in order to make calling functions faster in Clojure, Rich proposed the possibility of having functions take primitive values as arguments. This presents a new kind of problems; should primitive numbers be promoted to BigInt/BigFloat? when? ... interesting read.

Slides from my talk on metacircular evaluation at last night's CAPCLUG (here, via @fogus) -- Or how the magnificent 7 became the magnificent 3. Is there a video of this?

Another design sketch for Clojure coverage tool (here, via @lshift) -- In a previous article, the author proposed a macro that would instrument functions by wrapping their definitions. In this article the author proposes similar functionality but without macros. Work in progress.
