It’s highly context dependent if 1GB means exactly 2^30 bytes or another number in the neighborhood of 1GB.

by jonsen 6y ago
I may have used ‘exactly’ sloppy here. What I mean is: When the context doesn’t say otherwise, one should assume accuracy or precision as rounding to the least significant digit given. I.e. by default 1kg may indicate a mass between 500g an

I agree and I can tell, I once ported a 6809 program to Z80.

Same here :), but a beauty like 6809 is worth remembering.

Explosion is a faster speed of burn than what an internal combustion engine is designed for.

Does this imply that an emitted photon does not attain the speed of light instantaneously but has a finite acceleration? Likewise that an absorbed photon decellerates?

Take a 3.6MW generator. That is 3.6MWh per hour. As we have 3600 seconds per hour, it’s 1kWh per second. Say rotation is one per second, it’s 1 kWh per rotation for a 3.6MW generator. A few kilowatthours per day for an average home?
