Coffee break

A drip-brewed coffee, black and straightforward, served in a reclaimed mug. Not a grand cru: a functional brew that keeps you awake until the spanning tree converges.

You want the secret to a robust protocol? A coffee pot that never runs dry. In our labs, drip coffee flowed continuously — you'd fill the reservoir, start the machine, and refill everyone's cup without even asking. I drank it black, in the first mug I found, often engraved with a logo from a conference ten years ago. It wasn't refined, but it was loyal: it held strong while I tracked, line by line, why a bridge kept stubbornly looping.

How it was made : Electric drip coffee makers (like Mr. Coffee, launched in 1972) took over American offices and labs in the 1970s-90s, replacing percolators. The communal coffee pot, always on, became a central social object in technical workplaces.
