The departmental servers coxeter and sphere will have redundant power supplies installed and have their software updated, and the mail, web, share, ptr, and blog/wiki servers will have software updates applied tomorrow, Wednesday afternoon, January 22, 2014 which will require rebooting (most servers will be unavailable starting at 4:15pm). 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 requests@math.toronto.edu, so we can investigate). We expect the systems to be back up by 5:00pm.

The updated firefox that is now on coxeter is able to view PDF files within a tab. If you prefer you can still use a different viewer (for example, okular) for PDF files by choosing this at:
Edit -> Preferences -> Applications -> Portable Document Format (PDF)

Major coxeter update
The upgrades to coxeter’s hardware and software seem to have been successful. Information about the new coxeter will be added to http://www.math.toronto.edu/admin/coxeter-upgrade.html as necessary.
Please let us know as soon as possible at requests@math.toronto.edu if you notice any problems. It is better to let us know about problems early rather than wait for the start of the academic year when things are so busy that fixes may take a long time. In particular please test the new TeX and LaTeX (using pdftex and pdflatex is the recommended way).

Major coxeter update at 2:00pm on Wednesday August 14, 2013
Starting at approximately 2:00pm on Wednesday, Aug 14 we will be upgrading coxeter‘s hardware and software. The most noticeable change for users who use the coxeter GUI directly is that the only supported desktop environment is KDE4 which looks somewhat different than the KDE3 version from before. Please see: http://www.math.toronto.edu/admin/coxeter-upgrade.html for more detailed information about this upgrade.
We expect that coxeter will be back up around 5:00pm if there are no unforeseen problems. Please let us know (at requests@math.toronto.edu) if you have any problems with or questions about the new coxeter.
