Variables
==========
predefined variables :
- inventory_hostname (fqdn) (normally the same as ansible.fqdn)
- inventory_hostname_short
To know the return codes returned by ansible modules, just use plain ansible -vvv to see them :
ansible -i ~/ansible/arrfab.net/hosts/hosts.cfg -vvv -m copy -a 'src=files/sysinfo dest=/etc/sysinfo' tungstene.arrfab.net
tungstene.arrfab.net | success >> {

Fancy unicode arrows for emacs scala-mode. Done this way because I don't think it can work as an abbrev.
(defun right-arrow ()
(interactive)
(cond ((looking-back "=")
(backward-delete-char 1) (insert "⇒"))
((looking-back "-")
(backward-delete-char 1) (insert "→"))
(t (insert ">"))))

a nice .emacs for when you are on a terminal. Respects scroll wheel events. Very useful when run inside of tmux and combined with this tmuxconf: https://gist.github.com/ftrain/8443744
;; .emacs
;;; uncomment this line to disable loading of "default.el" at startup
;; (setq inhibit-default-init t)

Typeclass example
// Тайпкласс Animal (для полноты картины добавил метод hello, иначе был бы совсем тривиальный пример)
// Animal полностью абстрагирован от низлежашего типа A
trait Animal[A] {
def word: String
def talk() { println(word) }
def hello(a: A): String
}
// Обертка над тайпклассом Animal, чтобы можно было писать cat.hello, а не animal.hello(cat)
// AnimalOps полностью дублирует методы, определённые в Animal, но также может содержать еще и дополнительные методы.
