I don't think it's productive to enter into arguments about whether a  
particular operating system is a "monstrosity", "sane" or "a mess";  
that's why I limited my comment to a correction of a factual  
misstatement by Andreas and left the opinion part unchallenged. We  
could have avoided this thread if instead of "doesn't even have a  
case sensitive filesystem", he'd started his flame with "defaults to  
a using a case-insensitive filesystem".

While I agree that most just accept the default, your argument here  
and in your previous email is spurious; it amounts to saying "A and B  
is offered, but because A is the default it is the same as if B were  
not supported at all", which isn't valid logic. If you limited your  
argument to criticizing case-insensitive filesystems then I would  
have to agree with you; I am not a fan of them. Likewise, if you said  
that the default has undesirable consequences I would also concur.  
It's your attempt to extend your claim to an argument for equivalence  
that I can't buy.

Agreed...

but, don't you think you're exaggerating a bit here? How much  
"suffering" has this really caused you? I gather that you're not even  
a user of that operating system; I am (have been since the first  
developer previews), have always accepted the default filesystem  
choice, don't even like the filesystem (have ranted repeatedly about  
its flakiness on my weblog), but I think I've run into case- 
insensitivity issues two times. If you want to talk about "suffering"  
then ask me about HFS+ data integrity.

Read up on his posting history.

He is the main worker on the MSYS port of git as far as I can tell,
while not using Windows as his work platform.  So indeed he gets to
bear _all_ the pain, and no personal gain.  Since I have provided for
Windows/MSYS compatibility in AUCTeX's _installation_ procedure (a
small part of the project which is mostly operating system agnostic),
a much smaller stuff under similar circumstances, I can vouch for the
amount of hassle such a seemingly "everything we need should be there
in principle" Windows accommodation task causes.

And I actually find it extremely distasteful how little involvement in
this project is there from genuine Windows users: most restrict
themselves to complaining.

So at least on this account, I think you are not doing him justice.

If you look at the thread, his comments in this instance were about  
Mac OS X, not Windows.

As for Dscho's Window's-related pain, I do sympathize.

My original comment was in error. I was unaware that Apple shipped
different filesystems and that there was actually a choice. Me having
sat by a friend who did his installation didn't realize I had the option
of using a case-sensitive filesystem, so I assumed it wasn't there, which
only goes to show that assumption indeed is the mother of all fuckups. Not
wanting a pointless discussion in which everyone agrees in spirit but
nitpicks about factual details, I didn't respond to any of the posts.

Since it seems we all agree that case-insensitive, case-reporting file-
systems are disgusting and it's now thoroughly proven that Apple does
indeed ship a proper filesystem with its OS X releases, can we please
drop this now and move on to trying to improve things? I'll take
universal silence on the subject as "good idea, let's do that"

Plenty enough, I should imagine. As David Kastrup mentioned, Dscho
does extensive work on MSYS/MingW while not using it himself.

Besides that, there are all these timeconsuming threads that some
ignorant dumbass (in this case me) turn into silly pie-fights with
some uninformed remark that is overly tainted by personal opinion.

My apologies. I shall do my research better in the future.

Oh yes, they do. Guess what I spent the last month fixing in a huge heap
of proprietary software. Of course the problem is not truly fixable
because of the potentially unbounded set of context-dependent stuff such
as `Masse'.

(I hear some people got a summer holiday...)
