Re: [sage-support] sagenb.org server(s)
This is a such a big problem that a conference recently was dedicated to fixing it. Sometime this year there should be a new notebook system designed for dealing with lots of users. There are alternative notebook servers such as http://alpha.sagenb.org, but I don't recommend telling 75 students to use it. The notebook was not designed to be used by many users at once. So I recommend waiting until it gets redesigned for scalability.

[sage-support] Re: Problem in re-login to notebook using Mac
There's a bug in the error.html template. I'm guessing the error message would be about cookies not enable, see http://trac.sagemath.org/sage_trac/ticket/4429 for the report on that bug.

[sage-support] Segmentation fault
Hi,
On both the command line and in the notebook (my computer and
sagenb.org) with 3.3.alpha5 Sage closes after executing the following:
{{{
from jinja import Environment
env = Environment()
s = """{% for i in a %}
{{ i }}
{% endfor %}"""
tmpl = env.from_string(s)
print tmpl.render(a=[1,2,3])
}}}
In the notebook the error is
/home/sage/sage/local/bin/sage-sage: line 355: 19626 Segmentation fault
python "$@"
Connection to localhost closed.
If the Notebook looses connection to Sage should it automatically
restart Sage? Right now executing anything in the worksheet after the
error just comes back blank.

I'm trying to reproduce this for testing purposes. I'm using Firefox 3 on Vista. So far I can't reproduce this bug. 1) Create a worksheet. 2) Create a cell with sleep(3) print 'A' then evaluate it. 3) Create a cell below the first cell with sleep(3) print 'C' then evaluate it. 4) Create a cell above the second cell with sleep(3) print 'B' then evaluate it. 5) Click "Action..." then "Evaluate all". The cells should slowly be evaluated in order.

First load the Notebook object.
sage: nb = load('.sage/sage_notebook/nb.sobj', compress=False)
Adding a new user:
sage: nb.add_user('michael', 'AxhmjuK', '[EMAIL PROTECTED]', force=True)
sage: nb.save()
Changing user's password:
sage: nb.change_password('michael', 'CCDY')
sage: nb.save()
Deleting published worksheet:
Find the url of the worksheet you want to delete such as
http://sage.math.washington.edu:8999/home/pub/0/
sage: nb.delete_worksheet('pub/0')
sage: nb.save()
Deleting a user:
sage: nb.del_user('michael')
sage: nb.save()

[sage-support] Re: Notebook sign-up email
Hi Greg, I'm sorry to hear that this is causing you trouble with your system admin. I will take care of this issue first thing on August 1st. Currently the only purpose of email addresses being required in registration is to prevent people from being spammed who never signed up in the first place when someone tries to recover her password. But this system is clearly flawed. On August 1st I'll submit a patch that implements a notebook configuration keyword with the default value of False and tie the registration and password recovery system to it.

When you started the notebook did you do address='' or addres='192.168.1.104:631'? notebook(address='192.168.1.104:631') That's needed to allow outside connections.

[sage-support] Doctesting external files
Hi, I'm using Sage to doctest the code I've written for a new external project that I started. Currently I have to put ">>> from table import *" at the top of each of my doctest blocks. I don't want to have to add and remove this line before each release especially as my code base enlarges. I'm requesting that the Sage frontend to Python's doctest framework be made more intelligent when dealing with external files and projects. For example, maybe if a file is outside the Sage code base, then the frontend would add "from blah import *" to each doctest block automatically where blah is the file name minus the filetype identifier.

[sage-support] Computing discrete logarithm
Hi I want to know how to compute discrete logarithms in Z_p, but I can't seem to understand the explanation on http://modular.math.washington.edu/sage/doc/html/const/node63.html I understand that 125 in "sage: r = Integers(125)" is m but what is 3 and what is 17? Is 3 a or is it b? When I tried to figure it out: "print Mod(3^17,125) print Mod(17^17,125)" I got "38 52" neither of which is 17 nor 3. Could someone please give me a clear example of computing a discrete logarithm in Z_p. Like maybe using b = 25, a = 2, and m = 23. It would be nice if there was a function in Sage for computing this since this kind of computation is the basis for analysis of Diffie-Hellman which a lot of people learn about. --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://sage.math.washington.edu/sage/ and http://sage.scipy.org/sage/ -~--~~~~--~~--~--~---

When I use Sage to run: [simport.py] -- from sage.rings.integer import Integer I get Unhandled SIGSEGV: A segmentation fault occured in SAGE. This probably occured because a *compiled* component of SAGE has a bug in it (typically accessing invalid memory) or is not properly wrapped with _sig_on, _sig_off. You might want to run SAGE under gdb with 'sage -gdb' to debug this.

[sage-support] Re: [sage-devel] Secure Notebook Deployment
Hi,
The public notebook servers on sage.math.washington.edu are jailed
(http://sagemath.org/doc/html/inst/node10.html). Also there is a pool
of 30 unix users that are used to evaluate worksheet code. That
protects the main notebook system from a random user. Ulimit is also
used.
If I remember right William welcomes people to try to vandalize the
notebook server at https://sage.math.washington.edu:8102
---
How William runs the public notebooks from William himself:
(1) have a file that starts the notebook by running a .py file:
[EMAIL PROTECTED]:~/nb1$ more start_notebook
cd /home/server2/nb1
sage notebook.py > nohup.out &
(2) The actual .py file:
[EMAIL PROTECTED]:~/nb1$ more notebook.py
from sage.all import *
server_pool=['[EMAIL PROTECTED] -p 7000'%n for n in range(1,31)]
notebook(port=8103, accounts=True, address='sage.math.washington.edu',

[sage-support] Re: Fwd: Computer Algerbra Systems (not spam)
I am a high school student. "SAGE Beginners Book" seems to be more about computation in general than how to use SAGE to explore mathematics and get help on math homework. I like the idea of a Google Group for discussing SAGE for high-school students. SAGE includes SymPy so a student could play around with equations in pure python from the notebook. We really need a good geometry package because finding to find various intersections and what not without understanding geometry to make cool animations and stuff in SAGE is very hard.

[sage-support] Re: is_RealNumber does not work
Well I would like to make a Point class for a 2D coordinate system. So what is the best way to prevent most numbers with non-zero imaginary parts from becoming x and/or y in the definition of a given point? Like I would like to at least prevent 3 + i from being x and/or y. On 5/9/07, Justin C.

[sage-support] Re: calculus package fails on all general forms
diff(3) should be 0 but in SAGE it is an error. Shouldn't c be a
constant by default in SAGE, since many math textbooks use it as one?
{{{
f = function('f')
g = function('g')
view(diff(f(x)*g(x)))
///
{{\rm f}(x) \cdot {\rm diff}({\rm g}(x), x,
1)} + {{\rm g}(x) \cdot {\rm diff}({\rm f}(x), x, 1)}
}}}
It should be f''(x) + g'(x)

I think a calculus calculator where one could type in anything from a
standard calculus book and get the standard answer would be kind of
cool, but this is not important right now. The most important feature
wanted related to this is a way to see all the steps to solving some
calculus problem.
