Hi,
Tell me about it - I spend some time yesterday introducing a field
called "which factor of 1000 are we using today" into various
planning spreadsheets.
Can everyone not just give the numbers in bytes?
In practice, we should use 2^30 bytes as the 'base unit' of storage,
and scale from that. In the same way we don't use Avagadro's number
much when buying vegetables.
Ho hum.
Dave
PS: Nobody tell the PHB's about the horribly mixed factors of ten,
eight and two we use every time we talk about network bandwidth -
some weeks of discussion could ensue.
