2012-10-29 12:46:44 -0500 | commented answer | Restrict taylor() to only find genuine Taylor series Maybe another suggestion: test, if the function is well defined at the point which is the center of the Taylor polynomial. This should work also for multivariable series. Or expand along each variable separately and test the smallest power. |

2012-09-15 01:45:58 -0500 | marked best answer | No error messages in my Sage Cell server http://aleph.sagemath.org is running version 2 of the server, which has updated the error handling. http://aleph1.sagemath.org is running version 1 of the server. Indeed, it looks like aleph1 is not returning the error message either. There isn't any development work happening on version 1 anymore (since about the beginning of summer), so this is unlikely to be fixed unless someone submits a pull request. |

2012-09-10 22:28:11 -0500 | asked a question | No error messages in my Sage Cell server I installed sagecell server on Sage5.2 and I have two problems: with jmol graphic and error messages
If the computation finishes fine, I can see the output (including plots). If the computation fails, I see empty cell (and no div with error message in Firebug). The code throws error message on my server, as expected. However, the code throws error on aleph.sagemath.org, but not on my server.
I installed the sage cell server as follows: compiled sage 5.2 from sources, tested and installed tickets 12719 and 13121 following the instructions in the description to these tickets changed host IP address in sagecell_config_default.py (the installation in the text only virtual machine in vmware). allowed 'ProxyPreserveHost On' in apache configuration to keep correct url's, as described in one of the posts in sage-devel
Can you help me? Many thanks. The machine is installed on a server and apache2.conf is used to forward ports. However, the results are the same if I run the machine in VMware player and access directly from the same machine which runs the VMware player. |
