This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

I worked with a mainframe team at a casino. It processed all the transactions that went along with the machines and how much everyone was gambling.

Those machines were intimidating. Black, blue lights, the fans even sounded distinct. And the terminal emulator to talk to it made it seem even more esoteric and spooky.
