2012-02-09 13:10:05 +0200 asked a question Building Sage on the LittleFe Cluster

I've built Sage on the LittleFe teaching cluster, made of six Intel Atoms in a case I can carry from class to class (, if you're interested).

Sage works just fine on the head node, but won't detect the other nodes.

I ran import sage.parallel.ncpus and sage.parallel.ncpus.ncpus(), and just get 2, not the expected 12.

I tried putting "-machinefile ~/machines" into the argument of sage.parallel.ncpus.ncpus(), which is what I do with mpirun, but just got errors.

Emil: The SageLive CD vaguely worked with the Mac. Like running a Mac from the BCCD, though, the touchpad doesn't work. Jennifer Houchins at Shodor told me they bring mice to use with Macs with BCCD, but I didn't have a nest of mice to take. I did take CD's with the OS X version of Sage and my .sws file. I had a difficulty preparing the SageLive CD for PC's, though. What I wanted was a CD that would boot with both the Sage program and the Sage tutorial worksheet I was planning to present. I could create worksheets in SageLive, but was unsuccessful at Uploading from a USB drive. I clicked Upload, found the USB drive, and found the file, but when I clicked on it, the program froze. Turns out that the conference center had WiFi, so I didn't need the CD's.

I'm giving a session at the Louisiana Association of Teachers of Mathematics conference on using Sage in the high school classroom. Participants will bring laptops, probably a mix of Windows and Mac. There may not be WiFi in the conference center, so as a backup plan I want to have a stack of CD's to hand out, containing Sage, my Sage demonstration workbook, and whatever else needed to make it work.

The SageLive CD will work fine for the Windows people. My difficulty is that I don't know anything about Macs. Is there a foolproof way to put Sage on a CD such that a casual Mac user (a high school math teacher attending the workshop) could get it running?

Suggestions of other approaches?

Also in IE9, I just discovered, the "Sign Out" link isn't working.

@niles: As I understand compatibility view, the option only comes if IE determines the format is incompatible. The compatibility icon doesn't appear when I work in Sage, so IE9 doesn't think it's incompatible and doesn't give me the option to switch it.

2011-08-24 11:33:23 +0200 asked a question IE9: Loss of Sage Functionality

I'm using Sage in the high-school second-year Algebra course I teach, and many of my students use Internet Explorer 9.

When I open Sage in IE9, I lose some functionality. Shift-Enter does not evaluate, and "command( + Tab" does not open an options menu. There are probably more problems I haven't seen.

Is there a way to get full Sage functionality in IE9?
