Don't worry about that. Especially since...

Especially since you seem confused about who you're talking to -
the bit you quote above is something I wrote, but there's no "use of
binary" due to me anywhere here. (Maybe it was Ulrich? We clarified
that Ulrich <> Ullrich earlier, right?)

In any case, ego has nothing to do with the countablility of
the power set of the integers.

Indeed, the fact that the proof is a little trickier in binary
was "discovered" here on sci.math some time ago. (Alas the discoverer
took it as the reals were countable in binary...)
