Clojure code for a simple genetic programming system, for demonstration purposes.
(ns evolvefn) ;; Lee Spector (lspector@hampshire.edu) 20111018
;; This code defines and runs a genetic programming system on the problem
;; of finding a function that fits a particular set of [x y] pairs.
;; The aim here is mostly to demonstrate how genetic programming can be
;; implemented in Clojure simply and clearly, and several things are
;; done in somewhat inefficient and/or non-standard ways. But this should
;; provide a reasonable starting point for developing more efficient/
;; standard/capable systems.

Three Ways to Write Correct Chef Resources

This has been moved into the official Chef docs:

https://docs.chef.io/custom_resources_notes.html

12.5 style custom resources

This is by far the most recommended way of writing resources for all users. There are two gotchas which we're working through:

  1. For helper functions that you used to write in your provider code or used to mixin to your provider code, you have to use an action_class do ... end block.
