I’ve been trying to consciously slow down when responding to email, and send higher-quality, more thoughtful responses instead of knee-jerk reactions. Even so, based on this Time Before First Response chart, the people that I correspond with are still slower to reply to my emails than I am to theirs.

Source code for Apollo and Gemini programs -
The guidance computers for the Apollo space program used memory that was literally weaved into a physical rope:
Fun fact: the actual programs in the spacecraft were stored in core rope memory, an ancient memory technology made by (literally) weaving a fabric/rope, where the bits were physical rings of ferrite material.
“Core” memory is resistant to cosmic rays. The state of a core bit will not change when bombarded by radiation in Outer Space. Can’t say the same of solid state memory.
