For all the code heads out there, this looks an epic bundle of O'Reilly books dirt cheap.
There are $1, $8 and $15 packs depending on the books you want, all geared around Functional Programming in various languages including Scala, Clojure, Erlang, Haskell and JavaScript.
As it is Humble Bundle, you can decide how the money you pay gets distributed.
