Every time when I start to “play” with some software, I jot down a “damngram”, such as :

abc_software: dgddddggdddD
def_software: dddD
ghi_software: gggggD
jkl_software: dddggddddgddd
mno_software: D

A small d means “damn!”, but may be still working.
Big D means “DAMN !”, lose temper, don’t bother me anymore!
A small g means “good!”, I am somehow satisfied and willing to continue.
Big G mean “GOAL!”, the task has been done!

Today, I jot 13 big D , a mountain of d and 0 g/G on wikis …. -_-
