[sage-support] importing functions from other worksheets
If I have one worksheet, say global functions, that defines several general functions that all students should have access to, can they easily include the latest version of the code from this worksheet into their own worksheet with something similar to an attach or import command at the top? Or what other solutions are instructors using to address similar problems? Is it recommended to add function definitions to the init.sage file? I suppose it is quite easy to put these functions into a global.sage file and attach the file, but then the programs in this file have to be developed in a terminal window rather than in the notebook (unless I can figure out a simple way to save all input cells of the global functions worksheet to a file global.sage on the server that is accessible to all users). Any suggestions are appreciated.

[sage-support] New work sheet stopped working FireFox 3.5.4
I am using Sage 4.2 in VirtualBox and FireFox 3.5.4. The New Worksheet has stopped working. It brings up a previous worksheet. On earlier versions of Sage I had the same problem, however then I fixed it by empting the trash. The does not seem to work now. Is there some way to reset the New Worksheet funcion? I have tried reinstalling Sate 4.2 on Virtual box and then reloading my worksheets but that did not fix the problem Thanks Mike --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org -~--~~~~--~~--~--~---
[sage-support] html does not do Latex \xi
In both sagenb and using sage 4.2 in VirtualBox on an XP maching I think I found a bug. html( $\xi$) or any combinations of things using \xi does not work. If you press evaluate the cell never stops evaluating. It seems to work fine in the html text box above the cell.

What is your work around for the sqlite issue? On Nov 8, 12:13 am, Alex Ghitza aghi...@gmail.com wrote: I've been building Sage on 32-bit Archlinux for at least one year now. With 4.2, I only have two problems: the sqlite issue and the R issue. Thanks to previous threads on this sort of thing, I work around them by copying the system libreadline.so and libgcc.so to the appropriate places in the sage build directory. It's a bit annoying because as far as I can tell I have to wait for sqlite to fail before copying libreadline, and then for R to fail before copying libgcc. So the whole thing needs a bit too much of my attention. On the other hand, after that I have sage-4.2-goodness with longtests passing. There are no problems with Singular on my system.

[sage-support] Re: z-range issues in implicit_plot3d
Poking through the code I think line 922 in sage/plot/plot3d/implicit_surface.pyx should read: self.zrange = ranges[2][:2] I'd submit the patch myself, but I'd have to create a login and figure out the versioning system.
