A few notes regarding meetings via MS Teams:

  1. If you type in an email address and it does not show up in a drop-down (i.e. it’s underlined in red) you can still leave it on the list of emails and it will accept it and send an email to that recipient.
  2. If you have a list of emails in a text file, one email per line, you can copy and paste the whole thing into the Attendees field of an Outlook meeting. This also works if you have the emails in an Excel column, one email per line.
  3. Perhaps the simplest thing is to create the meeting and just invite yourself. You can then share the link which is emailed to you with whomever you want. For example, if you have a course web page you can just schedule all the classes, invite yourself to each, and then just post the list of links on the web page indicating when they should be clicked on e.g. “Class for Monday March 24, 10am: https://path.of.url”.

Power outage at Bahen

At approximately 19:30 on Thursday April 4th there was an extensive power outage across campus which also affected the Bahen building. Power to Bahen returned at approximately 20:15, and efforts to restart the computer systems at the Mathematics Department commenced at 20:30. All systems were back online by 22:15.

Server updates at 4:00pm on Thursday April 23, 2015

The departmental servers coxeter, sphere, and the web, share, ptr, and blog/wiki servers will have software updates applied on Thursday afternoon, Apr 23, 2015 starting at 4:00pm which will require rebooting. Since some updates will be applied while the servers are still up there may be some temporary issues with some software. We hope that any such issues will be minor and by doing most of the upgrading before bringing systems down the shorter downtime will be worth the potential minor problems. Please restart any programs if you observe problems during the upgrades (and please let us know at, so we can investigate). We expect the systems to be back up by 5:00pm.
