BigBlueButton Updates, tweaks

Firefox latest releases have become more aggressive about disallowing mixed http and https content on a single page. This caused the BigBlueButton Blackboard LTI to soft-fail until user manually overrode mixed content restriction. I was able to force BBB to use https only when referenced by the LTI, and force http for all else. This entailed hacking

/var/lib/tomcat7/webapps/bigbluebutton/WEB-INF/classes/ (see below) and /var/www/html



First fix broke presentations. Fix for that broke microphones. Fix for that fixed all — I hope.

if (top.location != self.location) {

top.location = self.location.href.replace(‘https’,’http’);


if (self.location.href.match(/https/)) {

Gund publications

I’m trying to upload an update of our publications database (as an xml file, per usual).  The import interface is hanging up, now motionless for 20 minutes after I hit submit.  Is this expected?  The files getting bigger, but I don’t remember such a long time before.
we still get lots of complements about the site.
This took a lot of sleuthing. Root cause was a database lock file (from November) that was gumming up the works.
Unrelated but also problematic: there was an issue with tomcat log files and the log rotate script resulting in wasted disk space and runaway jobs. All cleaned up now.
