Then at the top of spkg-install you just put sage -i dependency1 sage -i dependency2 This would work fine as long as there are no circular dependency loops. What do you think of this proposal? Works great as long dependency1 and dependency2 are in a place 'sage - i' can find. This makes the creation of meta packages superfluous!

[sage-devel] MPolynomialRing.__str__
Hi there,
I've submitted the patch
http://trac.sagemath.org/sage_trac/ticket/1816
to trac and Nick refereed it. The patch implements that if a multivariate
polynomial ring is 'print'ed the output is quite verbose and structured. This
behavior was in repr_long() before.
EXAMPLE:
{{{
sage: P.x,y,z =
PolynomialRing(QQ,order=TermOrder('degrevlex',1)+TermOrder('lex',2))
sage: print P
Multivariate Polynomial Ring
Base Ring : Rational Field
Size : 3 Variables
Block 0 : Ordering : degrevlex
Names: x
Block 1 : Ordering : lex
Names: y, z
}}}
Nick writes: That's *not* okay -- way too much by default but I disagree.
The motivation for adding more (structured) information to the long
representation came from the similar behavior of symbolic expressions:
EXAMPLE:
{{{
sage: f = x/var('y')
sage: f
x/y
sage: str(f)
'
x\r\n -\r\n
y'
sage: print f
x
-
y
}}}
Thus I figured it would be okay to have long representations returned by
__str__.
The question now is, how others think about it.
Cheers,
Martin

Will

like it but it won't bother me as much.

No, it would not. You can play with the behavior by considering symbolic
expressions:
sage: x,y = var('x,y')
sage: x/y
sage: print x/y
sage: str(x/y)

On Saturday 19 January 2008, Jason Grout wrote: bill.p wrote: Further info: I've retried it a large number of times and it only happens occasionally. It's not related to any particular cell or content as I have seen it on several different cells during this testing. I managed to grab a copy of 'view page source' while it was hung up but can't see anything obvious. I have had no further error messages relating to this in the error console despite several times when it has hung up. I have tried downloading the javascript file which is included (javascript/js.main) but never get anything back. Using view page source only shows the link to it. I tracked down the source of this to find that it is generated 'on-the-fly' by server/js.py which makes it difficult to follow. Does it vary depending on context? If you install the web developer addon for firefox (go to https://addons.mozilla.org/en-US/firefox/addon/60 and click install), you can see the *generated* page source (i.e., what you are actually seeing, not just what was originally on the page). Install the addon, restart Firefox, and note the additional toolbar. Under the View Source option, select View Generated Source to see the actual source of what you are looking at, whether or not the source was generated on the fly or originally was there. The web developer toolbar is one of the best things Firefox has going for it for web developers. Other things I've used it for were modifying the source or CSS styling of a page and seeing the page update in real time, examining the CSS structure of a page just by moving my mouse over elements, enabling or disabling features easily, changing the size of my browser to simulate smaller screen sizes, and lots of other things. The other firefox extension that might be useful here is Firebug, thought I think that at least some of firebug's functionality overlaps with web developer. Thanks for that. It looks really useful. Took me while to find what I wanted as there are so many facilities provided! All I have to do now is to get the problem to reproduce!

[sage-devel] generator inconsistencies in finite fields
I don't like the behavior illustrated below. Briefly, my problem is that
GF(p).gen() gives a generator for the additive group of GF(5), while
GF(p^n).gen() gives a generator for for multiplicative group of GF(p^n)
(n 1).
I would file this 'complaint' directly as a trac bug report, but the
documentation is somewhat clear that this is what is _supposed_ to
happen - i.e., it says
sage: F.gen?
Type: builtin_function_or_method
Base Class: type 'builtin_function_or_method'
String Form:built-in method gen of
sage.rings.finite_field_givaro.FiniteField_givaro object at 0x9c22324
Namespace: Interactive
Docstring:
Return a generator of self. All elements x of self are
expressed as log_{self.gen()}(p) internally. If self is
a prime field this method returns 1.
[...]
I also know that there is multiplicative_generator() method which always
does the right thing, but I still don't like this inconsistency.
Anyway, perhaps I'll turn my 'complaint' into a trac ticket, but I won't
bother if others don't consider this to be a bug.
-bober
p.s. The complaint illustrated:
sage: F = GF(25,name='x')
sage: x = F.gen()
sage: x # x generates the multiplicative group

Let me know what your experience is like with it now.I also made it so the notebook doesn't require a funny port, so it should work fine if you're behind some sort of firewall that doesn't allow connections to ports. Finally, I reduced the number of security warnings. -- William MORE DETAILS, and other changes unifying the servers: (Ignore the rest of this unless you're interested in more details etc.) I think it turned out that there was a huge amount of user data that was being saved every few seconds, so basically the notebook was spending all of its time backing itself up. This sort of paranoid constant backing up was really important when the notebook actually used to crash. Now the notebook can easily run for many weeks without crashing (in fact, I don't know how to crash it -- it just goes and goes). So I changed the parameters for autosaving. Thus if you've quit using the public notebooks in frustration because they feel very sluggish, please try again and let me know if they feel more robust and usable now. Also, I would really like to go from having three separate servers to exactly 1 server. The only reason we ever had three servers was because the previous (pre-twisted) version of the notebook would crash regularly, etc. The current notebook is far more robust. It would be better to have one server. However, I have nothing in place for migrating existing worksheets, etc. The simplest thing to do would be to just select one of https://sage.math.washington.edu:8101 https://sage.math.washington.edu:8102 https://sage.math.washington.edu:8103 to be the canonical one, make all the links point to it, and just leave the other servers running for people who want to directly connect to them (and tell people about them if they freak about their documents all being missing).

Sorry for coming into your discussion. I actually appreciate that x/y
and print x/y do different things, for the following reason.
If someone defines some sage object X and just types
sage: X
then the command is very short, and when i ask a short question, the
answer ought to be short as well.
On the other hand, if the user's demand on displaying X is more
elaborate, such as
sage: print X
then the displayed information should be more elaborate as well.
One reason that I don't like this is that in the notebook, only the
final 'sage: X' shows that way. Before that, one must use print.
Why the different semantics?
Currently in the notebook we have this behavior:
{{{id=14|
a = 5
a
2 + 2
///
4
}}}
Nick asks why this doesn't happen:
{{{id=14|
a = 5
a
2 + 2
///
5
4
}}}
The answer is --- I couldn't figure out how to implement the latter
(in sage/server/notebook/worksheet.py).
That's it. I just don't know how to do it. It's nothing more
mysterious than that. If I could figure
out how to implement the latter I would.

If this person's is right that you can't release a screenshot
of the
Sage Notebook under a CC license then I'm worried that the Sage
documentation can't actually be licensed under CC-by-sa since it
includes code from docstrings in the GPLed Sage code.
You can assure the people in that wikipedia conversation that it is
definitely
*not* our intention to disallow CC licensing screenshots of sage
that show
the documentation, and that I'm sure we'll be happy to work with
them
to clarify the license so that they'll be comfortable with those
screenshots
being on Wikipedia.
Unless I'm reading the wiki comments in the wrong way, they are not
concerned that we are disallowing the release of screenshots as CC-
licensed. The question is *can* we release screenshots as CC-
licensed, when the content is GPL-licensed.
Good point. However, we own the copyright to 100% of the relevant
GPL-licensed code, so we still get to decide the question of
whether or
not we allow the screenshots. I think they wikipedia people are just
being careful and respectful of our copyright, which I greatly
appreciate.
I don't get the same impression from the discussion there. I think
they (actually, belk) are asking a somewhat more general question,
although it's not completely clear what their point is. They are
discussing (elements of) GPL'd software. I can't tell whether they
mean
- a screenshot of something that is produced by software that is
licensed under GPL.
- a screenshot of a batch of software (code) that is licensed
under GPL; or
Consider:
This, regarding a shot of a display of a 3D plot of a function:
Claimed {{GFDL-self}}, but this is a screenshot of copyrighted
software. Are there enough copyrighted interface elements here to
make the screenshot non-free? —Bkell (talk) 05:48, 21 January 2008
(UTC)
and this, regarding the Sage shot, which includes Sage code (which I
will guess has *no* copyright attached to it since it's just a bit of
scripting to show the result [the plot itself]):
...What I am wondering here is whether this same restriction
applies to screenshots of GPL software. —Bkell (talk) 06:47, 21
January 2008 (UTC)
In any case, I think this could be an indicator of GPL licensing
beginning to capsize under its own weight (which will probably have a
lot of attendant collateral damage when it happens). I would be
cynical, but they're making it way too difficult...

[sage-devel] Re: Online free sage notebook slowness
On Jan 20, 2008 10:56 PM, Timothy Clemans [EMAIL PROTECTED] wrote: That worked. Did you do anything? No. The problem is that -- as has been discussed a lot already -- java applets are unfortunately rather flaky. In particular, each time you display a 3d plot in Sage it loads a jmol java applet, and after loading enough of those sometimes java just stops working.Something that will always fix the problem is to restart your browser. This problem was much worse in the older version of jmol before we released it with sage, so there may be jmol-specific fixes that help. Also, if you make 3d plots with a small figsize, e.g., = 2, it is almost impossible to trigger this problem. If anybody out there is a java expert, this might be a good problem to look at, where this is loading images many many times using sage's 3d plotting can lead to problems.

[sage-devel] Online free sage notebook slowness
Hi, This email is about the free public online Sage notebook server: https://www.sagenb.org I think I just fixed some scalability issues that were responsible for the online free Sage notebook server feel vastly slower than it should have. Let me know what your experience is like with it now.I also made it so the notebook doesn't require a funny port, so it should work fine if you're behind some sort of firewall that doesn't allow connections to ports. Finally, I reduced the number of security warnings. -- William MORE DETAILS, and other changes unifying the servers: (Ignore the rest of this unless you're interested in more details etc.) I think it turned out that there was a huge amount of user data that was being saved every few seconds, so basically the notebook was spending all of its time backing itself up. This sort of paranoid constant backing up was really important when the notebook actually used to crash. Now the notebook can easily run for many weeks without crashing (in fact, I don't know how to crash it -- it just goes and goes). So I changed the parameters for autosaving. Thus if you've quit using the public notebooks in frustration because they feel very sluggish, please try again and let me know if they feel more robust and usable now. Also, I would really like to go from having three separate servers to exactly 1 server. The only reason we ever had three servers was because the previous (pre-twisted) version of the notebook would crash regularly, etc. The current notebook is far more robust. It would be better to have one server. However, I have nothing in place for migrating existing worksheets, etc. The simplest thing to do would be to just select one of https://sage.math.washington.edu:8101 https://sage.math.washington.edu:8102 https://sage.math.washington.edu:8103 to be the canonical one, make all the links point to it, and just leave the other servers running for people who want to directly connect to them (and tell people about them if they freak about their documents all being missing). I just made 8101 the canonical one, since it is now the one most people use. [...] OK, I've now made it so https://www.sagenb.org etc *all* point to the same server. -- William Stein Associate Professor of Mathematics University of Washington http://wstein.org --~--~-~--~~~---~--~~ To post to this group, send email to sage-devel@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-devel URLs: http://www.sagemath.org -~--~~~~--~~--~--~---
