We don't need the newbies. We created Linux to make a decent OS. That
means it's stable, capable, a decent programming environment, useful, and
works. That doesn't mean it's so easy to use it does your work for you,
and hides common optins under little hoods marked "advanced options" (e.g.
options to actually make networking *work*). Maybe many of the clueless
eventually become clueful, but that doesn't mean we have to cripple the
operating system and make it completely inane so that they'll come in the
first place.

And the newbies that are so stupid that they avoid an OS because it makes
their disk *look* smaller[1], are very unlikely to be doing anything of
consequence. Those who are worthy will put in the incredibly small
investment to learn what a megabyte actually is.

[1] Which is really wrong in the first place. Chkdsk under DOS reports
disk space in bytes. df under Linux reports it in kilobytes. Both these
are right. So far, as far as I see, the only things that are reporting
disk space in "decimal megabytes" (which I still maintain is blatent false
advertising) are drive manufactuers, and maybe some lame Windows
applications -- though I think even Windows got it right.

You mean 2^20.

This is a really bad argument. I can simply say, "Convert the following to
the 10^9 or 2^20 in your head:"

1048576
4294967296
2147483648

(Hint: I know, from experience, that the number of bits in those numbers
is: 20, 32, and 31, respectively.)

But really, folks, this is why the the gods created 'bc' and multiple
virtual terminals.

Like it or not, the computer world works in base 2. There is a reason for
that. A bit has only two states: true and false. There are 8 bits in
a byte. There are 16 bits in a word. 32 in a 32 bit value (a long on the
PC architecture). If you can come up with an efficient way to redesign
computers to use bits with ten states, then go to base 10. Otherwise,
stick with base 2.
