If they did so, they’d also require Zamboni drivers to do their circuits in the opposite direction, counterclockwise instead of clockwise. They like to drive along the boards on the driver’s side so they can tuck up against the wall gently & see just how close they’re getting.

The worst was when someone left for vacation without releasing their file locks.

Only Mac OS 10 and later, based on BSD, uses ‘/‘. (And, I guess, A/UX.) Classic MacOS used a ‘:’, but it wasn’t regularly exposed in the UI. The only way most users would know is that the colon couldn’t be used in a file name.

With the exception of the recent Starliner fiasco, there are never more people on board the station than there are seats on the visiting spacecraft. In the event of a catastrophe, the Soyuz and Dragons function as lifeboats. To leave the station, you need to be able to close the station hatch from the spacecraft side. If you didn’t, the entire station would depressurize in your face when you undocked, which could cause a navigational hazard for the escaping ship.

Therefore, it must be possible to crank the station hatch shut from the visiting vehicle side, and, it stands to reason, the reverse is true.

This is a photo of the space-facing side of Shuttle / Dragon docking port on the station. The middle is a target to assist pilots in manually flying into the port straight and level. It was needed for the shuttle, newer spacecraft have automatic guidance. At 12 o’clock is a handle to help pull the hatch shut. (To open, you push the hatch in.) At 6 o’clock I believe is a socket you can put a crank into to seal or unseal the hatch. At 10:30 is a pressure equalization valve.

They’re able to recycle 93% of the water on the station. The leftover high concentration waste water, along with the poop bags, are loaded into a Progress or Cygnus cargo ship that burns up on reentry.
