*** Subject: M1. Is there any way to change the text in the title bar of a  
terminal window?

There is no way of changing the title bar of a terminal or
stuart window once it is running.  However in Stuart is
possible to get more descriptive titles by linking
/usr/ucb/rsh to /usr/hosts/<hostname>.  Then by adding
/usr/hosts to your Stuart ShellPath you can then get the
hostname into the title bar: 

	$ dwrite StuartShellPaths <various dirs>:/usr/hosts
	
You should then type in the hostname as the shell to invoke
(disable the "Shell reads .login file" for this.  You can
also add hosts to your .Stuartrc file:
 
	Shell=golem.ps.uci.edu
	SourceDotLogin=NO
	WinLocX=545
	WinLocY=563
	Lines=24
	|
	WinLocX=76
	WinLocY=833

For the localhost, link /bin/csh to /usr/hosts/<name>, or
even better /usr/local/bin/tcsh instead of using rsh 


[Garance A Drosehn <gad@eclipse.its.rpi.edu>] adds:

For what it's worth, I do this with a script called
"telnet_to" and a (bash) function called
"telnet_window".  The function simply does a 

     local soil_pars="-Lines 32 -Keypad YES -Reverse YES -Strict YES -TestExit  
YES";
     soil -Shell "telnet_to $1" $soil_pars

and the script is just:

     #!bin/sh
     /usr/ucb/telnet $*
     echo ' '
     echo '  -->   telnet exited, press enter to close window.'
     read -r Waste_Var
     exit 0

This has a number of advantages, not the least of which
being that I can pop up a "telnet_window" to anywhere.  I
don't have to create links for each host (though I do
create aliases for the most common hosts), and I can type
"telnet_window" (or, e.g., "tel_aix") as a unix
command.  Also, if I lose the connection suddenly then the
window stays around until I get a chance to see what
happened.  I use telnet instead of rsh because I generally
connect to hosts which won't accept rsh's. 


*** Subject: M2. Can I put both a 68030 and a 68040 system board in a single  
NeXT cube?

There is a company which plans to offer hardware (extra
CPU boards) and software support solutions for the OD
with Turbo NeXTcubes.  

For more information:

	Sam Goldberger
	Spherical Solutions
	smg@sphersys.net.netcom.com
	415-383-7512


[Note that we have no first hand experience with this
problem, we have compiled what we consider to be an
accurate report.  We acknowledge conflicting reports
where appropriate.]

In general Mach may be configured as a multiprocessor
operating system; however, the NeXT kernel is only
configured to deal with one processor. This
configuration can not be changed without access to the
kernel sources.  [hopefully NeXT will offer a
multiprocessor version of the NeXT operating system at
some future date]

Some have asked about the possibility of installing the
030 board for use as a printserver or other CPU-intensive
task server.  In this hypothetical setup, each CPU would
run its own copy of the operating system (essentially two
different computers sharing the same cube).

This might be workable except for the fact that even if the
NBIC (NextBus Interface Chip) chip is removed, the CPU
board probes the  bus for slot ID [**a conflicting report
comes from Richard Dib who heard that someone ran a cube
with the CPU in another slot].

You could do hardware modification to the 68030 board
which would isolate it enough to use only the cube as a
power supply, however you can not run two monochrome
monitor heads off the cube power supply. In this case you
would probably want to first boot the 68030 with a display
head, set the boot prom to boot off ttya, and attach an
ascii terminal to that serial port. 


*** Subject: M3. Where is libc.a under 2.0?

From the developer's release notes concerning the 2.0
NeXT Operating System Software available on-line with
2.0 extended: 

	/NextLibrary/Documentation/NextDev/ReleaseNotes/OperatingSystem.rtf 

- libc.a is not shipped with release 2.0.  All routines
contained in   libc.a are also contained in the shared
library libsys.a which should be used instead of libc.a. 
libc.a is not shipped because  as a normal archive it is
impossible for improvements and system interface
changes made to library routines to be applicable to 
existing applications without those applications
being relinked.   Applications referencing shared
libraries, because they are bound at runtime, always
access the most recent release.  Release 1.0 
applications linked against libc.a may not be
compatible with  release 2.0 until they are relinked with
libsys.a. 


*** Subject: M4. How do I get pictures of people from remote sites to appear in   
Mail.app and NewsGrazer? 

Mail.app:
In /LocalLibrary/Images/People put a tiff (64x64) in
the form of person@remote.site.domain.tiff (all
lowercase). In /LocalLibrary/Images/People/passwd
add an entry for the person:
person@remote.site.domain:*:-2:-2::/nodir:/noshell
(person and sitename need to be all lowercase as well)... 
In the future anytime you get mail from the person their
picture should appear. 


NewsGrazer:
In /LocalLibrary/NewsGrazer/People put a tiff (64x64)
in the form of person.remote.site.domain (all
lowercase).  This is a different naming convention from
what Mail.app uses. 


There is a large archive of some 4000 or 5000 pictures
prepared for this purpose. The name of this archive is
Faces3.tar.Z and it is about 4.1 MBytes large. Currently
it is available from several anon ftp sites (e.g.
sonata.cc.purdue.edu) in:

	/pub/next/graphics/Images/icons/people.


*** Subject: M5. How do I access the "help" facilities in Mathematica 1.0?

While the help dialog doesn't show anything, you
can get the help info by clicking on the place where the
slider bar should be.  This tidbit doesn't seem to work on
all systems though, and will be irrelevant once the new
version of Mathematica comes out. [Which it has].


*** Subject: M6. How do I find out what are the defaults for a NeXT  
application?

A PD App, DefaultMgr.app, is available on the NeXT ftp archives.

A more brute approach:

Start the application under gdb, and then try the
following sequence of commands: 

	break  *0x500976a
	commands 1
	silent
	printf "%s: ", *$a2
	output {char *}(4+$a2)
	echo \n
	cont
	end
	run


*** Subject: M7. How do I run NextApps remotely?

On the local machine make sure you have public window
server access, this is set from the Preferences
application.  On the foreign NeXT machine run the
application from a terminal window with the -NXHost
<local_machine_name>.  Both machines should be running
the same version of NeXTstep. 


*** Subject: M8. Why does UUCP hangs on outgoing connections after sending the  
password, but other communications software do not have a problem with it?

What is happening is that the remote machine is waiting
for you to end your login or password by typing a "Return"
(aka ^M or CR or CARRIAGE RETURN).  UUCP ends a line by
sending a LineFeed (aka ^J or LF).  Since UUCP doesn't send
the CR, the login sequence is never completed, and you
will usually get one of two error messages: 

	wanted "password:" (means that username needs to end with a CR)
	imsg waiting for SYNC< (means that password needs to end with CR)

So how do you get UUCP to send CR, instead of LF?

End the send string with the sequence \n\c.  For instance
this line in L.sys will send a LF after login, but a CR after
password.

	myfeed Any DIR 9600 cub "" ATTD19095551212 9600 \
	"" ogin:--ogin: Unext ssword: secret\n\c


*** Subject: M9. How do I access the NeXT's Digital Websters Dictionary from a  
program?

Get Jiro Nakamura's define program from the archiver
servers define.tar.Z.  This will allow you to access the
database from the command line. 


*** Subject: M10. How do I remap the \ and | keys on my keyboard?

NeXT introduced a new keyboard configuration with the
040 products. The \| keys which had been located on the
main keyboard was moved to the numeric keypad.  Many users
have since complained about it, and a work around is to
remap these keys using the demo application Keyboard
(/NextDeveloper/Demos/Keyboard), Mike Carlton's
keyboardfix program (on cs.orst.edu
next/sources/next-interface/keyboardfix.tar.Z)
which lets you put these keys on shift-return or
shift-delete.  One can hope that there will be a choice of
keyboards in the future. 


*** Subject: M11. Why doesn't email registration to Mathematica work?

There is a bug with this option where the mail instead of
being sent to Wolfram is stored in /tmp/email.message.
This file seems to be suitable for mailing to
register@wri.com


*** Subject: M12. How do I stop NeXTMail/Sendmail adding\ ^Ms onto the end of  
lines? 

In /etc/sendmail.cf make this change:

[old code]

	#####		UUCP Mailer specification
	#####
	Muucp,	P=/usr/bin/uux, F=msDFMhuU, S=13, R=23,

[new code]

	#####		UUCP Mailer specification
	#####
	Muucp,	P=/usr/bin/uux, F=msDFMhuU, S=13, R=23, E=\n,


*** Subject: M13. Where can I get black spray paint for my NeXT? 

Sprayon Paint
Omni-Packblend
4Next-Black (icon black)
LAV-16
25216

Call 1-800-777-2966 for the name of a dealer near you.
It's nominally $2.75/16 oz. can.


*** Subject: M14. What default affects menu location?

dwrite GLOBAL NXMenuX <value>
dwrite GLOBAL NXMenuY <value>


*** Subject: M15. How to get Gourmet to boot up the Mathematica 2.0 kernel? 

Login as root, or get root privileges running 'su', and
execute the following five commands: 

	mkdirs /NextApps/Mathematica.app/Kernel/NeXT
	cd /NextApps/Mathematica.app/Kernel
	ln -s uuuuu/Mathematica.app/Kernel/Display Utilities
	cd NeXT
	ln -s vvvvv/math mathexe

where uuuuu is the directory where Mathematica.app was
placed (typically, /LocalApps) and vvvvv is the
directory where the executable 'math' was placed
(typically, /usr/local/bin) 


*** Subject: M16. How to have the hostname show up on the NeXT login screen? 

As root:

	dwrite loginwindow HostName localhost

The "localhost" will be replaced with your system name.	
	

*** Subject: M16: How does one set UNIX man pages to be viewed in nroff format  
with DL like the standard manual pages?

Beyond looking in the man pages under ixBuild, etc., what
you want to do is put a few files (contents listed below
file name) the .index directory: 

	.roffArgs:
	-man

	displayCommand:
	tbl %s | nroff -man

	ixBuildOptions:
	-fman -Nwhatis -Ncat[1-8ln] -V

Other options that people suggested for ixBuildOptions:

	-fman -Nwhatis -Ncat[1-8] -V /usr/local/man
	-fman -Nwhatis -V /usr/local/man/man*

I don't think you need to explicitly name the directory in
the first alternative, but you do in the second unless you
want the cat* directories indexed as well.

Note: Do NOT leave a trailing return after the line in
ixBuildOptions; DL will barf.  (I think someone said
that, as shipped, the standard man .index/
ixBuildOptions had this problem.) 


*** Subject: M17: Can I automatically have my ~/.signature file appended to  
mail I send with Mail.app?

I want to automatically add additional header lines to mail going 
out from Mail.app (such as Reply-To or X-faces headers). Can this be 
done?

[Carl Edman]

Yes, on both counts. First create a simple text file the following 
content:

	#!/bin/sh
	{
	if test -r ${HOME}/.add-header; then cat ${HOME}/.add-header; fi
	cat -
	if test -r ${HOME}/.signature; then echo "--"; cat ${HOME}/.signature; 
	fi
	}| /usr/lib/sendmail "$@"

A good name for this file would be "sendmail-addheader".
If you want to  and can install it for system-wide use put
this file in e.g. /usr/lib.  Otherwise your private
~/Unix/bin directory is also fine. Make certain  that
this file has execute permission. To set that, use e.g.
"chmod 755  /usr/lib/sendmail-addheader".

Next, open up the preferences panel in Mail.app. Switch
to the expert  options. Change the Mailer option from
"/usr/lib/sendmail" (which it  should originally be) to
"/usr/lib/sendmail-addheader" (or whatever the  name
of the file you created is). OK this and you should be set.

From now on your ~/.signature file should always be
appended to all  mail sent out with Mail.app. In addition
if you have a file called  add-header in your
home-directory it should automatically be prepended  to
your outgoing mail. To implement a reply-to line, you
would simply  give it the following content: 

	Reply-to: My Real Human Name <name@my.real.address>

IMPORTANT: Make certain that you have one and exactly one
newline at  the end of ~/.add-header. Anything might
break outgoing mail. Beware !

BUG: The ~/.signature file is not added properly for NeXT
mail  containing attachments. The headers will still be
added properly. This  could be fixed but probably is more
of a hassle than it is worth.
