Quite true. I hear ya. I bet it will always exist, but I'm hoping it will be
the black sheep of the family.

Somewhat true. And yes, the overhead is there and is quite unavoidable.

I hope not. The more it is used, the more we need to deal with dual path
maintenance. Although... our code is a hella lot more organized than CVS, so
I doubt we'll have CVS's maintenance issues.

I won't say amazing, but my hope is to make it as damn near invisible as
possible. I know that we can get a lot prepackaged, but there will always be
the "what port?" issue. If you have N users on a system, they each need a
different port if they'll be running a private SVN server. And each user
will need to use that port in their URLs.

Hmm. I'm hoping changes will come from agreement rather than avoiding an
"immovable object." I actually feel quite bad when it seems that people
relent rather than agree. The part that is even worse for me, is that it
happens enough that I notice. It makes me apprehensive about whether I'm too
stubborn, too inflexible, etc. I hope that I'm open, but it invariably
devolves to "prove it is better" which isn't nearly as diplomatic :-(

I hear ya. I'd say you could blame me for it. I don't really know the
algorithm until I sit down to build it. I tend to iterate a lot more often
than design-up-front. For complex problems, I tend to let them simmer in my
head for a while. Eventually, it gels, and I begin coding. Point is: if you
ask me how something will be built, I rarely know :-) Sure, I can sketch out
some ideas based on the brain-simmer, but it isn't until the code hits the
keyboard that I'm truly sure.

Point is: two weeks ago, I may have been able to describe in general terms,
but I'm not sure that it would have been clear enough for us to meet on a
particular path. So... my fault.

But I can sympathize. I just rewrote the commit stuff last night. I think
I've rewritten the checkout once or twice now.

I hear the tense bit :-) ... I've been spending a lot of time in front of
the computer, and not enough on (ahem) planning/doing other things in life.
To get both done, it means little sleep :-)

But I tend to think of them as "discussions." It is impossible for me to be
angry with somebody for something they believe in. I tend to understand
others' positions, so I can see where they're coming from; I just tend to
disagree with those positions :-)
