Why does Xcode duplicate header non-Cocoa .h file in Contents/Resource ?

It's a bug. Upgrade to Xcode 2.1, or remove your headers from your
target's Copy Resources (I think that's the one). And check every time you
add new headers (if you don't upgrade), in case it adds those new ones.

Hmpf.  I finally installed Tiger, but XCode 2.0 does the same thing.
Where do I get 2.1?  I didn't even know it exists...

Oh yeah, haven't been there in *quite* a while.  Why don't they put new
XCode releases on Software update for those who have it installed...?

Because then you wouldn't have to sign up to ADC. :)

Because it's bloody huge and it would suck for everyone if everybody
tried to download it the day it was released.

I don't buy that. Regular OS updates can weigh in at upwards of 30MB.
While this is still a factor of 20 less than a full Xcode distribution, an
update package could be smaller, and I would wager there's at least 100
times as many people downloading OS updates as downloading Xcode updates.

They *did* put Xcode 1.1 on SU. Well, sort of. They actually distributed a
mini-update that updated the Xcode and IB apps but nothing else. This
result in a lot of confusion and a lot of semi-broken installations. I get
the feeling that since that experience, they've been reluctant to try it
again, even though there's nothing inherent about the SU process that
caused it.

Ah, but users en masse have less of an immediate desire to upgrade in my
experience. Certainly the total number of downloads for an OS update
will be much higher, but it doesn't happen all at once. Some people do
it immediately. Some wait a week for the early adopters to have first
crack at any new pain, and some wait even longer. I'd say it takes much
longer than a week and a half to achieve "full" adoption (i.e. all users
that will update, rather than those that can) of an OS update. Imagine
the impact, even if the audience is only 1% of the size, of Apple's
worldwide developer base pulling down 750M each in a 48-hour window.

Apple's Software Update already has mechanisms for distributing the bandwidth
peak across multiple servers and over multiple days. As far as I know, the
answer here is simply that the left hand is not talking to the right hand and
that there isn't much pressure for them to do so, especially since the new tools
already have to be posted on ADC one way or another, so also posting them in SU
would simply add red tape and overhead.

My experience is generally the opposite. Normal users tend to have upgrade
fever, whereas developers usually undestand the business enough to hold
off for a while.

In any case, 1% is probably an extreme over-estimate, as is 750MB, just as
48 hours is an under-estimate.

I'd be surprised if the Xcode update traffic were any significant
proportion of total SU traffic, even as a spike.

Just took it from your post.

The size of the last Xcode download.

My projection of the window during which developers would be trying to
download an Xcode update if they became aware of it through SU based on
the totally anecdotal observation I've made of developer behavior.

But it's all speculation on both our parts as far as I know. Possibly
amusing, but unlikely to actually be productive, yeah?

It was meant as an extreme over-estimate in that post as well.

Compare the size of OS X (several GB) to the size of even a large combo
updater (117MB for the 10.3.9 updater). Xcode updates will probably
replace more stuff, but it will still be significantly smaller.

My observation is that developers have been burned by installing updates
on their work machines and try to hold off until they hear back about how
they work. But people are different.

Indeed. I have no illusions about the actual *usefulness* of this sort of
usenet discussion. :)

XCode 2.1 contains kind of own software update that informs at least
about new available documentation on the ADC member site.
