Friends Kingdom: Re: [iPad] I've been struggling to learn my iPad well enough to actually use it.

The term bug came from bugs shorting the relays. Those were earlier machines than valve using ENIAC.

In valves, bugs can not short the contact points since they are sealed, hence the name Vaccum Tubes for them.

ENIAC was made to plot the trajectory for ICBM's to USSR, 80 bytes of memory, I think that is pretty dang impressive for the day. Took up a few floors of a building, but even so. The term bug came from bugs shorting out the valves in ENIAC iirc

Years ago, article on the Cray Computer, also back in the day. The PC of the time of the article was an Intel Celeron CPU, a budget CPU, blew the Cray away. I assume Moores Law is still working

I spent the summer of 1969 at the Manned Spacecraft Center south of Houston. The Apollo flights were managed by several (3 or 5) linked IBM 360/50 mainframe computers, each of which probably had the storage capabilities of an iPhone, but not the speed.
