Regarding the freeze problem only (I think I have bothered more than =20

- Antivirus software like ClamXav scanning directories in the =20

With Virex incompatible with Tiger, and now than ClamXav has reached version 1 and is more compatible with =20
Tiger (it doesn't fuss with the NetInfo clamav user pre-installed by =20
Tiger), I am using ClamXav for antivirus scanning. It can scan =20
folders/drives on demand, and includes a Sentry function for scanning =20=
specified directories automatically. I have set the Sentry to scan =20
the Desktop (my download directory) and the various Inboxes and Junk =20
mailboxes of my Mail accounts.
That said, as with any virus scanner I have tried so far, this Sentry =20=
function ends up invariably at some point with unexpected slowdowns =20
nay crashes, and I will probably, as always, disactivate automatic =20
scanning and only leave scanning on demand (for email attachments, =20

About equation editors: Wendy McKay from TUG noticed the existence of
the commercial MathMagic , which exists as a personal edition and several pro
editions. It's fully WYSIWYG, and doesn't seem to be TeX-based. The
personal edition is stand-alone, while the pro ones include the stand-
alone application plus either InDesign or XPress plugins; the pro
editions seem to also include additional functions, like exporting
colored equations while the personal edition only exports B&W output,
and PostScript fonts while the personal edition only includes
TrueType and OpenType fonts.
The equations can be pasted in applications like Keynote apparently,
and double-clicking the pasted equation brings back to the editor for
modification. More details in .
That said, the pricing seems prohibitive IMO for an equation editor
-- compared with what we get for free with TeX-based editors (for
example, $30 academic with 6-month subscription for the personal
edition, *and* $200 academic with 6-month subscription for the pro
InDesign edition).

Howdy,
I see mdimport (one run under my user name and occasionally one run
with no user (root?)) running about once every 10s taking about 15%
of CPU (on my 550MHz Powerbook) for a short period of time - it's
running "niced" so I believe will hold off if necessary. There is
also mds which runs irregularly and I don't know what it does - no
man page for it. I assume that if I had a faster processor the CPU
usage of the periodic mdimport run would go down considerably or at
least the time period would decrease quite a bit so there would be
less interference with other processes running (although that
shouldn't happen, ever!). I do wonder if this is the culprit when pdf
files were being messed up when I re-compiled too rapidly since the
process is tied into the low level disk reads and writes.

The network time out seems to be very long and this problem seems to
be in every version of OS X I remember. I make sure to turn off
automatic checks for updates by applications; it would be handy but I
remember wondering what happened to my system when Expander couldn't
get in touch with it's site and would hang for a long period of time.

Did you actually run the Virex un-installer? It has helped

done anything.

I have been using ClamXav ever since it came out. The only
disadvantage is that there are no searches inside .sit files. That is
getting moot now since .zip has become ``standard'' under Tiger so
everything I compress goes into .zip now.
The latest version of ClamXav will open with a Drag & Drop but
doesn't seem to actually search the dropped file(s). That is the way
I like to do things---nothing in the background. Hopefully Drag &
Drop will be improved in the future.
Good Luck,

Subject: Stupid question on TeXShop
From: "Bruno Voisin"
Date: Wed, 27 Jul 2005 14:42:28 +0200
A certainly stupid question: where is Windows Latin 1 encoding in
TeXShop's Document preference panel? I can see Mac OS Roman and Iso
Latin 1, as well as a bunch of other encodings, but not Windows Latin
1. Is it there under a different name? I searched the help with no luck.
Reason for asking this: I'm trying to help a colleague working with
MikTeX and WinEdit on a Windows PC collaborate with a beginner TeX
user on a Mac with TeXShop; both need accented characters. After
trial-and-error we've found out WinEdit uses Windows Latin 1 encoding
(we've not been able to find any pref setting the encoding in
WinEdit), leading to \usepackage[ansinew]{inputenc}. It thus would
help to set TeXShop to use Windows Latin 1 as well, or at least to be
able to import Windows Latin 1 files (rather than requiring separate
installation of an encoding converter such as Cyclone).

Actually I had removed Virex manually (didn't know there was an =20
uninstaller). I suppose the reason for an uninstaller was that there =20
were not only the Virex GUI application inside /Applications/, and =20
the Scheduler application inside /Applications/Utilities/, but also =20
the actual scanning engine and the virus definition files inside /usr/=20=

Howdy,
Exactly my reasoning with Archive & Install but running the un-
installer really has helped. See for information on getting the script for
your version and then take a look at the script; things seem to be in
lots of places. Running the script can't hurt since rm can't remove
what isn't there.

Well, looking at the file EncodingSupport.m in TeXShop's source code =20
it seems there is no provision for Windows Latin 1 encoding in =20
TeXShop's editor, and only the 24 encodings appearing in the pull-=20

However there exists indeed a corresponding string =20
NSWindowsCP1252StringEncoding in Apple's Cocoa API , which seems to indicate it should be possible to modify =20
EncodingSupport.m to add this encoding to TeXShop. I won't venture =20

It would be nice to have a modifiable list of recognized encodings, =20
as in TextEdit (at Preferences > Open and Save > Plain text file =20
encoding), or maybe to have TeXShop inherit its list of encodings =20
from TexEdit.

Hello all,
when writing Greek characters in LaTeX I would like the luxury to be abl=
e
to write
Greek characters directly in the source file, (that is, I want to write
"here is some greek text : ??? ???" instead of
"here is some greek text \textgreek{\bla\lambda\alpha \bla\lambda\alpha}=
" in
the .tex file). The "not so Short Introduction to LaTeX" probably
contains the answer to this, but I must confess that I did not understand
all of it.
The following source file :
###########################################
\documentclass{article}
\usepackage{ucs}
\usepackage[applemac] {inputenc}
\usepackage[T1]{fontenc}
\usepackage[french,greek]{babel}
\begin{document}
here is some Greek text : ??? ??? ???
\end{document}
###########################################
makes LaTeX interpret the english characters as Greek characters
and the Greek characters as semi-colons : all wrong ! If I change "applem=
ac"
to "utf-8" the output remains the same. What small change must I make
to have this bilingual source file correctly interpreted by LaTeX ?

Use xelatex or omega (which both grok Unicode).
See http://scripts.sil.org/xetex for starters.

Does it work with [utf8] instead of [utf-8]? An alternative solution =20
is to switch to XeTeX .

Try this file:

%% note that LaTeX/Babel tries to think for you, so you don't need to =20=
insert spaces before punctuation even though you're writing in french
%% Comapre to this:

Just an FYI, which you may wish to take with a grain of salt: In a
recent meeting to discuss ways to deploy and use Xgrid at my campus, a
local tech support guy noted -- and the Apple rep on hand confirmed --
that the Mach kernel doesn't actually respect 'nice' settings. The
tech support guy called it a "placebo": the user sees the nice setting
(say in 'top'), but the kernel (reportedly) completely ignores it. The
Apple rep was from marketing, not engineering, FWIW.
I don't have the expertise to verify this claim as fact. However,
this information might help explain why some people are seeing
slowdowns with what appear to the naked eye to be "niced" jobs.
Perhaps a subsequent kernel update will in fact support 'nice'-ing
processes....

Hi There:
I writing to report an annoying bug in TeXShop (I am using version

one moves the cursor vertically through a document. I have not been
able to replicate the problem in a reliable way, although it seems to
occur more often if I happen to work with a split window.
Has anyone seen this? If yes, has anyone pinned down the cause of the

In other UNICes nice too isn't what it was ten or 15 years ago. I've
found that a nice'd process cannot make the CPU fan start on a portable
-- i.e. the processor seems not to be switched from minimal to maximal
speed.
For me and my PowerBook this is a valuable feature: I can safely start
long compilations before I go to sleep (make bootstrap for Emacs, fink
update-all) or visit the public swimming pool to cool down myself ...
and when I return revived I have a new FontForge or such!

If that happens to you, you have not installed the proper fonts. =20
Either use some postscript font (times, palatino, lucida, =85) or =20
install some complete computer modern variant =97 CMSuper (available as =20=
an i-Installer package, includes some cyrillic characters) or Latin =20
Modern (already installed, requires the use of \usepackage{lmodern}) =20
=97 if you can't live without CM.
As to why you'd want this, you actually give a good clue yourself: =20

I've also seen measurable differences when changing task priority
using 'nice'.
A possible explanation for the tech support guy's assertion is that
the darwin task/thread priority mechanism is complicated enough that
it doesn't map well to what you learn about unix in school.
(At least, not what *I* learned about unix in school!)
According to the docs, there are separate scheduling 'bands' as well
as priorities within that band.
This is why programs can hog the CPU but easily not make the mouse
movement choppy, or skip iTunes, for instance. When you use nice, it
puts that process into a separate band. The docs don't say
explicitly, but it's implied that the order of band priorities goes:
graphics server, dock, background apps, foreground apps, (re)nice'd
processes, then other.
OK, that's enough offtopic OS stuff from me. If you want to see where
I got this from:
http://developer.apple.com/documentation/Darwin/Conceptual/
KernelProgramming/scheduler/chapter_8_section_4.html
FWIW, I've seen some bad performance from spotlight too.

This is an issue that Bruno Voisin and Gary L. Gray have dealt with in this
mailing list.
It is not a TeXShop bug, but it rather seems to be a Tiger (very annoying
indeed) bug.
It does happen to me in TeXShop, Mail, Entourage, BBEdit, etc.
Best,

I think if you search hard enough on this list, and go back several
years, you'll find some messages from the developer, trying to sell
us on their software. I delivered some comments, and apparently they
appreciated those comments, and gave me a license. The user interface
is very similar to the Word equation editor: IMHO it isn't really
pleasant (naughty words removed).
At the time they just added some TeX export, but I have no clue how
that could ever get past QA: the tex code just will never compile,
due to issues with fonts, and plain coding errors. I haven't tried
the MathML export followed by an XSLT translation, and frankly I have
no use for such an editor, so I don't really feel inclined to try it
out.
I didn't think the output is particularly spectacular, the same
typographic glitches that are produced by MathType are present here
as well. It feels like a MathType clone.

It would be interesting to figure out how they do that. It should be
visible in the xml document produced by Keynote.

The pricing is not the prohibitive part IMHO, it is the time limited
license: you cannot open your own documents without a valid license.
Imagine you cannot open a document from one years ago, because you
choose not to renew the license. That is even worse than MS Word!
