Why are you all "upset" about this?
This is _very_ old news. (The long and short of it is actually that
the HDD makers were actually right. That they might have had another
motive than promoting a standardsbased view is... beside the point:-).
As someone mentions, there are approved ways of stipulating binary
multiples now, so... use them if you need to make the distinction
clear;-). One might argue that Jules is simply "enforcing" the SI
normative in a consistent way... Which is a very good thing.
Makes life so much less ambiguos when we don't have to have any more
"1.44M" diskettes (that are actually 1440 KiB... Sigh) and suchlike.
