jsMath Now Available
An article in TUGBoat reminded me of the existence of jsMath, a way of including mathematics in webpages without having to translate the material to MathML or embed images.
In Your Webpages
You can now use jsMath in your webpages to include math. This method is especially useful for homework problems, examples, or other bits of mathematics that you might want to include in a page. (It might be especially useful for any thesis student websites where you want to display math in your abstract on the webpage!)
To use it, you need to add some code to your webpage to load the necessary JavaScript libraries and to tell jsMath what material it should try to typeset.
In the header of your document (i.e., inside the <head> tags), add the following line:
<script src="/jsMath/easy/load.js"></script>
The Getting Started page suggests that you also include code to warn users if they have JavaScript turned off in their browser.
Once you have the
<script> tag in
place, you should be able to type
mathematics in your webpage's source
code using the \( and
\) delimiters for inline
math, and the \[ and
\] delimiters for display
math.
I've left the default delimiters on for
now; it's possible to use
$...$ or
$$...$$ as
well, but those uses require you to
escape (as in TeX) any dollar signs
that might appear in your page. If you
think we should change them, let me
know, and we can try to get the
department to agree.
More information about creating webpages with jsMath is available from the authoring manual.
Extra Bonus Feature: jsMath in Wikis
I have also installed a jsMath plugin for the MoinMoin wikis that we run. To use math in a wiki page, you should be able to start the page with
#format jsmath
and then type math in
$...$
delimiters for inline math or
$$...$$
delimiters for displayed math. (Yes,
using the $$ is evil, but
whatever.)

More on hex
I have pulled out the CPU expansion
board from hex and sent it
back to the vendor, who is going to try
to get a replacement from the
manufacturer. In the meantime,
hex is running with eight
cores (four CPUs) and 16 GB of RAM, and
it seems to be stable.
Please let me know about any problems, and check back here for updates.

Update on hex...
We've been having some issues with
hex this year, which seem
to be related to memory. Initially we
leaned toward thinking we had a bad
DIMM, but we weren't able to isolate
the problem to a particular DIMM. So we
swapped out all the RAM on the
daughterboard (a huge circuit board
that's only slightly smaller than the
machine's motherboard and supports four
processors and their RAM), and, well,
we're still seeing the same issues.
So now suspicion falls on the daughterboard. The vendor is checking to see if we can get a replacement.
So hex is still running
with less than its full complement of
memory, although it now has 24 GB
active.
Stay tuned for more....
