Following entry was written by Richard Stamper. I moved it here for persistency:

On the matter of automatic calculation of fields, it is possible using included javascript but you have to do the work yourself.  For example, we have a log which computes responsivity as the ratio of a photocurrent and optical power.  With log attributes called "Photocurrent", "Optical Power" and "Responsivity" there is a file in the logbooks directory called photomixer_javascript.html containing something like:

<script>

if (document.form1.Photocurrent) {
  document.form1.Photocurrent.onchange = new Function(
    "mod();"+
    "var power = parseFloat(document.form1.Optical_Power.value);"+
    "var current = parseFloat(document.form1.Photocurrent.value);"+
    "if (!isNan(power) && !isNan(current) && power != 0.0) {"+
    "  document.form1.Responsivity.value = Math.round(current/power*100)/100.0"+
    "}"
    );
  document.form1.Optical_Power.onchange = document.form1.Photocurrent.onchange;
}

</script>

and the elogd.cfg file includes

Bottom text = photomixer_javascript.html

for the relevant log.

The assignments to the onchange handlers are guarded because this javascript is included on all pages for that log, including the list pages where there is no such field as Photocurrent, (or Optical_Power) and the event handler function is defined dynamically for the same reason.

The attached script was used by the Debian package (which is no longer maintained) to start/stop elogd. I have changed it based on some comments in the forum (see script) to add some more functionality. As there is no mainatined elog package for Debian anymore, I'm placing it here in the hope that it might come in handy for users who want to run elog under Debian.

This script needs to be placed in /etc/init.d and expects elogd to be installed as /usr/sbin/elogd (can be changed, of course).

A Mini-Howto for apache2: 

apt-get install apache2
apache2-ssl-certificate
(and answer the questions)

Now, enable ssl:
a2enmod ssl

configure ssl:
cp /etc/apache2/sites-available/default /etc/apache2/sites-available/ssl
ln -s /etc/apache2/sites-available/ssl /etc/apache2/sites-enabled/ssl 
"/etc/apache2/sites-enabled/ssl" should look like this:

NameVirtualHost *:443
<VirtualHost *:443>
(... configure the directories too...)
and "/etc/apache2/sites-enabled/default" should look like this:

NameVirtualHost *:80
<VirtualHost *:80>
(... configure the directories too...)
In /etc/apache2/ports.conf, add Listen 443

In the middle of /etc/apache2/sites-available/ssl file, insert this two lines:

SSLEngine On
SSLCertificateFile /etc/apache2/ssl/apache.pem

Hope it helps :)
