	It'd be best if someone can do the hands on as well
as the non-hands on stuff.  However, since nobody is {able,willing}
to step up to do so, I don't see a problem with splitting the
task set - i.e. if we can find somebody/someplace (ISC, or ??) that
is willing to handle the physical machines, and we can find others
to handle the config/admin/etc. (all the non-physical stuff), seems
good to me.

Didn't that request require the potential admin to have the ability  
to also physically deal with the machines?  I think that definitely  
limits the potential pool of people.  If all the machines have good  
console servers attached, then at least anything short of true	
hardware failure could be handled remotely.  Also, being at ISC  
(they're still at ISC, right?), are there techs available for doing  
things like HD swaps, power cycling, and the like?

As far as spam goes, I think I see just a couple a day to mine,  
maybe, though I don't track between OD and other domains which have  
had valid email addresses for quite some time...

Hi Rob,

If I had root access to the server, I would volunteer to help.	
However, it appears as if OS X Server is setup to use with Amavisd  
which runs as a daemon. Additionally, any changes I would make to the  
SpamAssassin configuration to support including spam status and  
scores in email headers would also likely require root access.

Do you think there is anything I can do beyond creating my own	
whitelists and blacklists using procmail recipes that wouldn't	
require root access?

A better question is do YOU have any plans to do anything about OD spam?
I sent out a request many months ago for a primary OD admin.  I got a
couple of responses along the lines of "I'd like to help OD, but I don't
want the responsibility".  So, you can try to get a hold on one of the
half dozen intermittently available people with administrative privleges
on the OD machines at admin@...

That said, you have sftp access to the OD machines, procmail is the local
delivery agent, and spamassassin is installed on OS X server by default
it would appear.  Feel free to volunteer to tackle the mail situation
on OD, or cobble together your own solution.

Never tried firefox, but I did have my Wallstreet running OpenDarwin 
6.6.2 with WindowMaker and some software useful to my needs (networky 
stuff, python and emacs) and it was more than adequate.

I expect that a lot of the power management settings are specific to 
proprietary OS X so that battery will last longer under that.

Cheers,

Graham.

I have just installed OpenDarwin on my Wallstreet

Harold Johnson (harold.johnson@...)

Hello all,

A couple of day ago I installed OpenDarwin on my PowerBook G3 Wallstreet.  I
selected version 6.6.2 because it is the most recent version (that I know
of) that doesn't require XPostFacto to install.  (I had a bit of trouble
with my open firmware after installing the most recent flavor of OpenDarwin
-- I believe it was 7.2.1 -- with XPostFacto 4.)

I'm currently installing fink 0.11.1 from source, following the instructions
located at :

http://fink.sourceforge.net/news/jag-bootstrap.php

Then I hope to get X11 going on this system, as I'd like to have a GUI on
this old PowerBook.  I don't currently have OS 10 on this system, plus I
only have 256MB of RAM.  Do you all think X11 running -- let's say, Firefox
-- will run better on this system then Firefox on OS X on this system?
Also, would a battery last longer running OS X Aqua or X11?  Just curious
about your opinions.  More details about my system:

PowerBook G3 (Wallstreet 2/PDQ)
CPU: 233MHz
RAM: 256MB
Expansion bays: CD-ROM: 20X, floppy drive, and ZIP100 (seems broken)
Newertech NuPowr 4500MAH batter (brand new)

LOL, I'm bragging about my system, which was stunning perhaps in 1998 or
so...

Hope to hear your opinions about running X11 as opposed to Aqua,

Harold J. Johnson

Strange things in math.h under Intel OSX

Max Persson (koexistens@...)

Hi there,

It seems like Apple may have done some mistakes in their port
of the standard c library (which I seriously doubt). I bumped in to
this problem when I compiled
some tests for OpenEXR (under Intel OS X on a MacBook Pro). It says
that a function from math.h is invalid. As you may know, there are two
versions of some of the stuff in the std-c library, one for ppc and
the other for i386. math.h is one of them. There is a macro/function
called isnan() that determines if a float is a number or not, and it
was here I bumped into the strange things. I opened up both versions
of math.h and compared the implementation of the isnan() macro...


Here is the one in the i386 math.h:

#define isnan(x)	       (       sizeof (x) == sizeof(float )    ?       __isnanf(x) 
	  :	  sizeof (x) == sizeof(double)	  ?	  __isnand(x)	  
	:	__isnan (x))


And here is the one from the ppc math.h:

#define      isnan( x ) 	( ( sizeof ( (x) ) == sizeof(double) )
?					 __isnand ( (double)(x) ) :
						( sizeof ( (x) ) == sizeof( float) ) ?
				       __isnanf ( (float)(x) ) :
					     __isnan  ( ( long double )(x) ) )


The one that is used in my particular case is the first of them as I
am on a i386 OS X. What I have learnt, you always put surrounding
parenthesis in macros to prevent them from failing due to strange
input. That is NOT the case in the i386 math.h (along with a couple of
other macros there too).


The input argument in the call to the isnan() macro is in this case:

isnan(pf[y][x])


What I belive is happening here is that the macro gets very confused
with the array access here, because of the missing input parenthesis
in the macro. This is what I got from the compiler to further
strengthen the theory:

testTiledCompression.cpp:59: error: expected unqualified-id before 'sizeof'
testTiledCompression.cpp:59: error: expected `)' before 'sizeof'


But enough talking about this. I do not look for a quick fix here,
what I'm concerned about is that Apple may have delivered a faulty
math.h file for the Intel version of OS X. What do you think about it?

Max Persson

Hi, uhm...sry, sent this to the wrong adress ;)

IMO, there is no need to bother wether it is a logical/primary partition.
Usually you can have up to 4 primary partitions. So, no problem to put it on  a primary.
As stated in
http://opendarwin.org/en/articles/booting_on_x86/
you should only bother 'bout using the correct filesystem type. In this
case, UFS.
Of course you should think about your Bootloaders. I don't know how to
Dual Boot Darwin & XP but i think you will make your Darwin UFS partition
the active one, as that is where the machine will boot from.

stephan
