When i feel like taking a break to watch a video but now ads are everywhere, thought of this neat elisp script to turn off the volume for a specified number of seconds (otherwise defaults to 30) and message me when the time's up on a Mac OS X, using osascript... now if there was a way to switch back to my browser :) i'll try that on stumpwm!

skip-ads.el

(defun jqt/skip-ads (&optional seconds)
  "SECONDS default to 30"
  (interactive "p")
  (let* ((seconds (number-to-string (or seconds 30)))
         (command "osascript -e 'output volume of (get volume settings)'")
         (output (shell-command-to-string command))
         (current-volume (replace-regexp-in-string "[\s\n]" "" output))
         (set-volume-command "osascript -e 'set volume output volume %s'"))
    (shell-command (format set-volume-command 0))
    (message "Ads stink!  Turned volume (was at level %s) off for %s seconds..." current-volume seconds)
    (run-at-time (concat seconds " sec") nil
                 (lambda (v cmd)
                   (shell-command (format cmd v))
                   (message "Ads should be done now... phew!  Turned volume back up to %s." v))
                 current-volume set-volume-command)))
