[CAD Outsourcing <CADout@xxxxxxxxx>]

hi Chow,
I understand what you are saying, and you are perfectly correct in a
theoretical world. You can be arrogant all you want, but that is not going
to change the fact that we livein an imperfect world, where all the planets
and starts are NOT in alignment to make everything work perfectly as you
mention, when recompiling for 64bit. In the real world we live in,
applications are not perfect, many things aren't done perfectly, especially
when you have programmer contributors with various backgrounds,
philosophies, and skill levels.
The proof is in the bugs.  The proof is all the other 64 bit Ubuntus out
there that are reputed to be less stable than their 32bit counterparts...
even by their developers own admission, as you can often see the mention on
the download pages "64bit is generally less stable. If you want a stable
version, download the 32bit" can often be read.
Saying the opposite is either ignorant pretentiousness, or just a big battle
of egos going on.  None of which is productve in any way to the bettering of
the project.
Some of the points you brought up as an attempt in displaying
contradictions, were made to demonstrate the contradictions made by the
Lubuntu team: trying to make a faster distro that will run better on old
hardware, and sacrificing stability, for a no-benefits-64bit version for the
computers this is going onto.
ANYONE with a very very very fast computer will NOT be able to perceive the
SLIGHTEST performance difference on their computer, brought about by this
distro in 64bit. BUT what they WILL see, what will stick out like a sore
thumb, is the elements of the distro that were neglected and are still
buggy.
Don't be naïve: 64bit DOES require extra human resources - there is a lot of
debugging and fixing to do, because once it is recompiled in 64, strange
things happen... and when you run those 32 bit apps on a 64 bit OS, you'll
slow down anything that is not the new generation intels of this year (not
exactly the crowd that would want lubuntu anyways).
(It's the same problem as we had with .com versus .exe program files in DOS
and Windoze (I just like to call it windoze) - many were not compiled so
they still need an interpreter, because after compilation they may not have
been as stable.  Otherwise everything would have been compiled on that
platform.)
And btw, all the apps we need are not all available in 64 bit. Skype for
one, Gimp, and many others as well.
If we had to choose, we would rather see a bug-free 32 bit version, and only
32 bit available, than having both maintained but some elements or features
missing or not working properly because human resources were diverted away
just to make another flavor.  Heck, some of the bugs were found in other
ubuntus versions ago, and are resurfacing!  I'm too frustrated at playing
this game of participating in getting things fixed that were already fixed
long ago but are resurfacing as problems in this distro at this time.
