To not allow any dot files or directories (hidden in unix) to be seen if they are in a directory available to the webserver, add the following to the httpd.conf file.
# The following lines prevent any .files from being viewed by web clients.
<Files ~ "^\.">
Order allow,deny
Deny from all
</Files>
We don’t really have any hidden files (like .svn) on our website, but this should protect us in case someone accidentally puts on there.

By default, we have banner pages off, but if someone wants to print a banner page, do this:
lpr -o job-sheets=standard file_to_print
Here’s a screenshot of the relevant cups manual.
First of all, note that scipy requires python >= 2.4. SC4 comes with python version 2.3. So, a newer version of python needs to be installed first. For us, it was installed in /code/hep/bin.
Numpy can be installed for either python 2.3 or 2.5. For 2.3, use yum.
yum install numpy
For the 2.5 version, download the tar file, extract and run:
/code/hep/bin/python setup.py build --fcompiler=gnu /code/hep/bin/python setup.py install --prefix=/code/hep
This will put the libraries in /code/hep/lib/python2.5.
For scipy, download the file, extract and run:
export PYTHONPATH=/code/hep/lib/python2.5 /code/hep/bin/python setup.py install --prefix=/code/hep
Then, to use the 2.5 version instead of the 2.3 version, put in your .bashrc file:
export PATH=/code/hep/bin:$PATH export PYTHONPATH=/code/hep/lib/python2.5
On one computer, I was having some problems running yum upgrade. It would complain that a dependency wasn’t installed. However, I could rpm -q that dependency and it showed up fine. To fix this, simply uninstall the package that was the dependency and then run upgrade. That should cause the dependency to be automatically downloaded and installed.

We currently use WinEDT and MiKTeX to allow users to edit latex files in windows. APS provides the revtex4 package for their authors.
To get this package to work with MiKTeX, make the following directory structure under your localtexmf tree.
mkdir/tex/latex/revtex4/
Then run,
Start -> All Programs -> MiKTeX -> MiKTeX Options and click the “Refresh Now” button in the “File name database” section. That’s it.
The APS website above has a sample file that can be used to test things out.
Edit the file wp-content/themes/default/sidebar.php. Right after this:
<li>
<?php get_search_form(); ?>
</li>
</pre>
add this:
<li>
<?php wp_list_bookmarks(); ?>
</li>
Edit ../wp-content/themes/default/index.php and archive.php.
Look for a line like this:
<small> <? php the_time('F jS, Y') ?> <-- by <?php the_author() ?> --> </small>
Edit to this:
<small><? php the_time('F jS, Y') ?> by <?php the_author() ?></small>
In archive.php, the by <?php the_author() ?> needs to be added.
