Actually, it's even more wrong than you think -- the admin user can now
add regular users from the notebook. Log in as admin, then click on
Settings -> Manage Users -> Add User. The text above should definitely
be updated.
Thanks for pointing this out. This is now

[sage-support] set_edge_label is setting labels on intended and unintended graph
set_edge_label is setting labels on intended and unintended graph I generate some graphs and set one's edge labels. When I look at the next genetated graph, it's edge labels have been changed. I'm new to Sage/python so perhaps I goofed, but I doubt it. Thanks for an explanation or workaround. I am trying to help my daughter investigate an edge coloring graph theory problem. Not the normal edge coloring constraint, though. See the I added to the output section. for G in graphs(3): if G.is_connected(): A = G.adjacency_matrix() print "Adjacency Matrix:" print A print "Edges:" for e in G.edge_iterator( labels=True): print e #G.plot( edge_labels=True ) print "Setting edge labels..." for i in G.edge_iterator( labels=True): #print i #print type( i ) G.set_edge_label( i[0], i[1], 'Red' ) print "Adjacency Matrix:" print A print "Edges:" for j in G.edge_iterator( labels=True): print j #G.plot( edge_labels=True ) print "" Adjacency Matrix: [0 1 1] [1 0 0] [1 0 0] Edges: (0, 1, None) (0, 2, None) Setting edge labels...

In which case put that directory in your path earlier. It's impossible to build gcc with just Fortran support, so I would suspect there is a gcc 4.2.1 and g++ 4.2.1 on your system. Finding where gfortran is, would probably lead you to the location of the more recent gcc and g++. I suspect someone build gcc 4.1.3 without Fortran support, then built a later version with Fortran support. If 4.1.3 is in your path first, then the old versions of gcc would be found, but a new version of g+ +. Mixing compiler versions would be risky. That is why I added that test.

[sage-support] Docstring on adding a user
Hi,
The following is an excerpt from the docstring of notebook() about how
to add a new user:
accounts – boolean (default: False) if True, any visitor to the
website will be able to create a new account. If False, only the admin
can create accounts (currently, this can only be done by running with
accounts=True and shutting down the server properly (SIG_INT or
SIG_TERM), or on the command line with, e.g.,
from sagenb.notebook.notebook import load_notebook
nb = load_notebook(dir)
nb.set_accounts(True)
nb.add_user("username", "password", "em...@place", "user")
nb.save()
Trying to follow the explanation, I spent some time just to fail. Now
having succeeded to add a user, I think the documentation is obscure.
How about the following or something better?
... If False, only the admin can create accounts. Currently to add an
account, shut down the server properly and type on the command line,
e.g.,
sage: from sagenb.notebook.notebook import load_notebook
sage: nb = load_notebook(dir)
sage: nb.set_accounts(True)
sage: nb.add_user("username", "password", "em...@place", "user")
sage: nb.save()
where dir is the directory of the sage notebook with default being
`.sage/sage_notebook.sagenb', and restart the server.

[sage-support] Documentation update request
On the web page http://wiki.sagemath.org/DownloadAndInstallationGuide, there is some slight misinformation for Macintosh computers which seems to be causing some people to have confusion about which version of Sage to install. If the Processor type is reported as "Intel Core Duo", people should be directed to install the 32-bit Intel version of the software, even if the O/S is running MacOS X 1.5 or greater, because these processors are 32-bit and not 64-bit, even though the O/S is 64-bit capable. Running the 64-bit application on a 32-bit processor will result in the commonly found error: > -- > | Sage Version 4.3.2, Release Date: 2010-02-06 | > | Type notebook() for the GUI, and license() for information.| > -- > env: python: Bad CPU type in executable Kevin Marinelli UConn Mathematics -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org

Each allocation gives a large chunk of memory to the process, and then the process allocates from that new chunk until it runs out, and then the OS allocates more (at which point, get_memory_usage() reports a larger size).
