1 where's the idea come from?

I hang out in the #emacs IRC channel in freenode one day, and some guy show some funny trick that can always make some fun:
fortune | cowsay
Every time I execute this command, the output always let me LOL.

                ||----w |
                ||     ||
So I get a idea, why not put this trick into my email signature. I can send email with those magic that's awesome. But some email client don't support a script powered signature, Fortunately I am emacser, It's so easy to add a hook in my email mode. So cool! huh! Enjoy this trick!

(defun fortune-cowsay ()
  (interactive)
  (save-excursion
    (goto-char (point-max))
    (insert "\n")
    (insert "------------------")
    (insert "\n")
    (insert (shell-command-to-string "fortune | cowsay"))
    (insert "------------------")))
(defun zpcat-signature ()
  (interactive)
  (save-excursion
    (goto-char (point-max))
    (insert "\n")
    (insert "Regards,\n")
    (insert "Yours\n"))
  (fortune-cowsay))
;; add fortune-cowsay to message-mode-hook
(add-hook 'message-mode-hook 'zpcat-signature)

2 how to use it?

Load above elisp code into your emacs, and It can works.

So why google changed its Bluetooth stack? The reason is maybe that Bluez stack was designed for the desktop environment, so in order to port Bluez into android, android must solve some dependency issues, like porting Dbus, Linux desktop's default IPC, into android. So there are at least five processes to power Bluetooth before android 4.2, they are systems, Bluetooth APP, Bluez, hciattach, and Dbus. The damn thing is that there are bugs between them, so Bluetooth stack is the weakest part in the android system before android 4.2, yeah, it is the usual reason that android system corrupted. So, what's t
