thanks, I tried all that on www.sagenb.org.
I could access files many of the files of 221 visible 'users' in /
home,
like some vincent, a certain notorious wstein, a victor, a carlos, a
Ulrike etc. by
import os; dn = '/home/some_user'; os.listdir(dn);
os.chdir(dn); fin = open('some_file'); fin.read(); ...
but I could _not_ access a directory /home/risse which is me on www.sagenb.org
Imho this is a security leak and at the same time rather dodgy:
I still do not know where to find my *.sage, *.py or *.pyx files on
www.sagenb.org
which I want to import into another worksheet. Any help very much
appreciated, EM
