coxeter will be rebooted at approximately 4:15pm tomorrow (on Wednesday, Apr 9) in order to apply some updates due to the recently disclosed openssl problem.  We expect coxeter to be back up by 4:30pm.

The other departmental servers have already been updated and will not be rebooted.

The following is from UofT’s IT Security people (Quick Summary: upgrading to the latest versions of iOS and MAC OSX will fix this serious security problem, but that does mean going to iOS7.0.6 for iPad and iPhone users, which many people have avoided):

There has been a recently discovered flaw in Apple products
which affects how SSL certificates are validated.

Apple has just released a patch for OSX (10.9.2), please
update all OSX devices ASAP.

More details about OSX 10.9.2 are available here:
http://support.apple.com/kb/HT6150

If you haven't already patched iOS devices (iPhone, iPad,
etc), please update to 7.0.6 ASAP.

More details about iOS 7.0.6 are available here:
http://support.apple.com/kb/HT6147

You can test if your device is vulnerable by visiting this site:

For those interested in the details of the vulnerability itself,
there's a good writeup here:

coxeter and sphere appear to be working fine now, after the updates late this afternoon.

The main departmental servers coxeter and sphere will have software updates applied this Wednesday afternoon, September 25, 2013 which will require rebooting.  Since some updates will be applied while these 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 these  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 about 5:00pm.

Complimentary MATLAB seminars for educators, academic researchers and students at the University of Toronto have been scheduled:

Date: Wednesday, September 4, 2013
Location: Bissell Building, Room 205
Time: 10:00 a.m. – 12:00 p.m.
1:00 – 3:00 p.m.

The event features two technical sessions presented by MathWorks engineers:

10:00 a.m. – 12:00 p.m.: Session 1: An Introduction to Data Analysis and Visualization with MATLAB
Learn how to acquire, analyze and visualize data through mathematical, statistical and engineering functions.
1:00 – 3:00 p.m.: Session 2: Parallel Computing with MATLAB
Learn how to solve computationally and data-intensive problems using multicore processors, GPUs, and computer clusters.

New sphere

The update of hardware for sphere went smoothly.  The new machine is faster and we have installed the latest versions of:

  • Magma (version V2.19-7); type magma to run it
  • Mathematica (version 9.0.1); type math (CLI) or mathematica (GUI) to run it
  • Matlab (version R2013a); type matlab to run it

As mentioned before we are negotiating to get the newest version of Maple as well.

There is some free mathematical software on sphere as well:

  • Asymptote, a powerful descriptive vector graphics language; type asy (CLI) or xasy (GUI) to run it
  • Axiom, a general purpose computer algebra system; type axiom to run it
  • Macaulay2, a software system devoted to supporting research in algebraic geometry and commutative algebra; type M2 to run it
  • Sage, a free open-source mathematics software system licensed under the GPL which combines the power of many existing open-source packages into a common Python-based interface and whose mission is to create a viable free open source alternative to Magma, Maple, Mathematica, and Matlab; type sage to run it
The new sphere has over 1TB of scratchspace (space which is NOT BACKED UP, to be used for temporary files only, that may disappear at any time) for users.  Each user has, in additional to their home directory mounted from coxeter, a directory in /DO_NOT_BACK_UP/scratch/<user’s account name>.

The Licensed Software Office would like to pass along the following invitation.
