I have not put effort estimates on my tasks for a long time.
Tonight, I was playing chess and saw a "notify" message come up on my
Linux box that <some task> should be finished by now.
Wow - I never knew org-mode had that built-in! I ran a git-blame on the org-source
code [1] and it's been a long time, right? I haven't tested whether it sends a Growl notification
on OSX but that's really cool!
(It was kinda creepy at first, though)
Thanks,
