2018-10-31 16:58:38 +0200 commented question 500: internal server error on reading data files and on publishing worksheets

I found the problem seems to be in the following line of sagenb/flask_version/worksheet.py: upload_url = worksheet_upload_data.url_for(worksheet) But I do not know what it may be. Any help?

2018-09-13 08:57:07 +0200 commented question 500: internal server error on reading data files and on publishing worksheets

I have the same problem in Sage 8.3 in a Debian 8 distro. The error mesage is:

Could not build url for endpoint 'worksheet_upload_data' with values ['id', 'username']. Did you mean 'worksheet.worksheet_upload_data' instead?

I used http://wiki.sagemath.org/SageServer to configure apache to act as a proxy for Sage and provide the ssl conexion. I have to modify something and it is not working perfect (once I get it to work fine, I will detail here). Thanks.

2015-10-10 23:54:33 +0200 answered a question Factoring expression involving exponentials

Maybe by a change of variables:

sage: var('k,w,p')

sage: expr(k,w,p)=exp(4ik+3iw+ip)-exp(4ik+2iw+2ip)-exp(4ik+2iw)+exp(4ik+iw+ip)+2exp(2ik+4iw+ip)-
exp(2
ik+3iw+2ip)-exp(2ik+3i*w)

sage: f(k,w,p)=expr(log(k),log(w),log(p))

sage: g(k,w,p)=f.canonicalize_radical()

sage: g(exp(k),exp(w),exp(p)).factor()

Greetings,

I have a sage server for my students. I have a ssl cert (and a CA) for the server address, but I do not know how to tell sage notebook to use it instead of the one it generates. Note that it is a running server used by many students (around 200), so I can not try many things.

Regards,

José Luis

I got it working. Just adding r.png() at the begining and r.dev_off() at the end of the cell.

2013-09-20 04:09:45 +0200 commented answer R graphics/plots in sagenb

I got the same problem. I just followed: http://ask.sagemath.org/question/192/compiling-r-with-png-support installed all the libraries, compiled the R and r.eval('capabilities("png")') returns true, and r.eval('capabilities("X11")') returns False. When I plot something in R, I get a broken icon (I am running Sage 5.9 via ssh from a remote server).

I have tried modifiying the status of the worksheet inside a worksheet and I can. I put the worksheet as archived but it still shows in the active. If I run it from the command line sage it works. I do not understand.

2013-08-29 16:16:29 +0200 answered a question Problems archiving shared worksheets

I have done a bit more of research. I have the same problem in the 5.10 version installed in my computer. I can archive the worksheets when I run the sage in the command line, so it seems it is a problem with the permissions or the interface.

2013-07-24 13:37:31 +0200 answered a question Problems archiving shared worksheets

With Sage 5.0 it was different. My students share with me their homeworks in sage (so I can revise them), so I have really a lot of worksheets. So it would be very usefull to be able to organize them (at least to archive the marked worksheets).

2013-07-23 04:22:32 +0200 asked a question Problems archiving shared worksheets

Hello,

I have Sage 5.9 installed. When one user shares a worksheet with me, I can modify it, but I can not archived it or delete or unshare.

Thanks!
