2014-02-02 02:07:53 -0500 | commented question | frozenset error when plotting polytopes: bug? i can reproduce this. If it helps you for the moment ngon=polytopes.regular_polygon(122).dilation(181/10) works. |

2014-02-02 01:58:56 -0500 | commented answer | Running SAGE notebook files across multiple platforms via Dropbox And now it doesn't work any more?? :/. It was ok for about 2 days. I'm confused, sage planted some symbolic links in my dropbox folder |

2014-01-29 22:30:05 -0500 | answered a question | Running SAGE notebook files across multiple platforms via Dropbox I can't tell you where this error comes from, but i also got it when setting up syncing with Dropbox lately. As was mentioned in this question Dropbox has a problem with symbolic links. So I have come to a working solution for me by just symlinking the actual folder of my notebook files, which is this done also on my laptop works very good for me. Don't forget to put the files from I have no idea about symlinks in mac os and I can't garantee for anything though.. Greetings, marv |

2014-01-27 03:37:16 -0500 | asked a question | integral() failing with "segmentation fault" Hi sage community My question again arises from exercises in technical chemistry done in sage. I wanted to calculate an definite integral (number of transfer units). The first two methods work fine. The last method gives me the infinite of the following messages. This is a bug, isn't it? However, i have no idea how integrate() works. Greetings, marv |

2013-11-16 00:29:28 -0500 | answered a question | computation limtations in Sage cloud Ok, I think i figured it out. The problem is, that i filled many lists with exact expressions and i exeeded the memmory available. Take the following lines from the loop: After changing them all to something like: everything works fine. Thanks for tmonteil for your offering. If you want you can still take the code and have a look at your system memory. Maybe it would be good, if sage cloud tells if too much memory is used. |

2013-11-15 23:26:51 -0500 | asked a question | computation limtations in Sage cloud Hi everybody I'm working on an exercise in technical chemistry and try to find concentration progresses by numerical calculation. Note that im pretty new to Sage and Python. The problem i encounter is that as soon as i want to use more than 20 iterations, Sage cloud doesn't finish. I was able to have more iterations when my loop was smaller. Is there a limitation on the computional power, that is provided by Sage cloud? If you think the problem is with my code, I will post it.
