What/Where is that 'push notifications for favicons' tutorial/script i saw on here a while back?

Anybody have it bookmarked? I cant find it for the life of me, searched google, tried reddit, tried twitter, github... nothing.

These?

If not, roughly how long ago, and was it recent when you saw it?

YES! That 2nd one. Thank you!!!!
