To install stuff needed to run chef in a solo mode (Small one or two server configuration):
gem install knife-solo
To setup chef after it has been installed:
| (defmacro def-curry-fn [name args & body] | |
| {:pre [(not-any? #{'&} args)]} | |
| (if (empty? args) | |
| `(defn ~name ~args ~@body) | |
| (let [rec-funcs (reduce (fn [l v] | |
| `(letfn [(helper# | |
| ([] helper#) | |
| ([x#] (let [~v x#] ~l)) | |
| ([x# & rest#] (let [~v x#] | |
| (apply (helper# x#) rest#))))] |

| Hello scala, my old friend | |
| I've come to take you home again | |
| Because a feature slowly creeping | |
| left me plagued with doubts and weeping | |
| and the version that was tagged in the repo | |
| just has to go | |
| it lacks the signs of soundness | |
| On sleepless nights I hacked alone | |
| applying ant and other tools of stone |

| // This character generator is similar to the default one from ScalaCheck, but it filters out: | |
| // 1. Unprintable control characters. These cause problems in Mongo queries, and should not able | |
| // to get into our database since they will not be present in inputs parsed from HTTP text. | |
| // 2. Characters that do not exist in the default platform encoding. We can exclude a big range | |
| // of these right away (which ScalaCheck does) because they're in the range used for two- | |
| // character UTF-16 sequences, but others are only detected by checking Character.isDefined(_). | |
| // The symptom of using a bad character in a string is that when you encode it to UTF-8 and | |
| // back again, you get a different string, so any of our web and database tests that check the | |
| // input against the output may fail-- and you'll see a question mark somewhere in the data, | |
| // since that's how bad characters are displayed. |
