execfile('/foo/bar.py') works for me. Check the path.

Is there a way to start an instanace of Sagenb that is open to everyone on the network without a need to login?

I have some Python scripts and I need to run them under notebook.

I run the scripts in %Sage -python <scriptname>.py. It works fine If I run it under sage shell by execfile('/foo/bar.py'). It works fine as well

But if I run execfile('/foo/bar.py') in Sage Notebook, it complains about

...cannot open shared object file: No such file or directory

It appears to me that the notebook can't find the lib. Does Sage and SageNB uses a separate Library-path and Run-path?

Hi!

I know Sage has a simple server API that you can start/moniter a Sage calculation via a terminal. But is there a way to use it to access existing Worksheets that are already in SageNB?

In reference to the Simple Server API here: http://www.sagemath.org/doc/reference...

You can pickle the resulting object and then read it into another Sage session, if that is your question.

For example, in the first Sage session:

sage: result = 42
sage: result.dumps()
'x\x9ck`J.NLO\xd5+\xca\xccK/\xd6\xcb\xcc+IMO-\xe2\xcaM\xccN\x8d\x87q\n\x19C\x99\x0c\x13[\x83\n\x99\xf4\x00\x88\x14\x0f\xc5'

Then you can load the pickled object in another session:

sage: loads('x\x9ck`J.NLO\xd5+\xca\xccK/\xd6\xcb\xcc+IMO-\xe2\xcaM\xccN\x8d\x87q\n\x19C\x99\x0c\x13[\x83\n\x99\xf4\x00\x88\x14\x0f\xc5')
42

For simplicity I used dumps/loads to save/load strings. If you have large objects you probably want to use dump/load and save the data to a file. Of course you need file system access on the Sage server, then.

Updated: How well is compatibility with intermixing Sage code and R code? For instance, if I want to do:

f = r.read.table("bar.txt", row.names = NULL, header=T, sep=";") calling some sage function and prints some output

but it didn't work as Sage can't find the corresponding R "table" method. But I do %r and just use "read.table(...)", it works flawlessly. But I can't use the pass the R timeseries to Sage list.

Is there a better way around this?

I am running some lengthy calculations on the Sage Notebook, and I want to access them later on another client terminal that doesn't have a browser. Is there some ways you can "ask" the Sage Server and it gives the result? If not, is there a way to direct result to another client terminal?

Thanks,
