Anyone know any good DM cheat sheets or random generators? (In Dungeon and Dragon Magazine)

I've recently been creating and DM binder and have been trying to find useful things to put inside. I've recently begun to actually look through Dungeon and  Dragon magazine but I don't have the time to sift through everything just yet. I've already got a few combat cheat sheets as well as Sly Flourish's DM sheets. But I've also got a few generators that I've printed from Dungeon and Dragon, like the Character Background generator from Dragon issue 422, and the Instant Inn generator from Dragon issue 418. Does anyone know of anymore in Dungeon & Dragon? It doesn't have to be from the magazines. But I find that they are typically more in depth.

ENWorld's tavern generator is simply brilliant.
