[sage-devel] Updating from 9.1 to 9.2

[Kannappan Sampath]

Hello everyone:

I am trying to update from 9.1 to 9.2 and I think I broke my sage in the
process. I have a copy of sage-9.1 built from source and tried to update as
follows.

[knsam@locmach sage-9.1]$ ./sage -upgrade
must source sage-env-config before sage-env
Error setting environment variables by sourcing
'/home/knsam/Downloads/sage-9.1/src/bin/sage-env';
possibly contact sage-devel (see http://groups.google.com/group/sage-devel).


On googling, this seems to have been reported earlier but I don't know how
to fix it now. I would appreciate it if you can point me in the right
direction!

I'd also appreciate some hand-holding as to good practices for updating my
local copy of sage... Thank you!

   Best,
   Kannappan

[sage-devel] Re: Sage Magma interface

[Kannappan Sampath]

Hello everyone: 

After some poking around (and hat tip from Marc Masdeu), I notice that the 
source for the error might be in part due to the following: 


[knsam@gl-login1 magma]$ echo $SAGE_ROOT
/sw/lsa/centos7/sage/9.1

For some reason, sage is looking in $SAGE_ROOT/lib/sage/ext_data/magma/ and 
from what I can see, in my installation, there is no such thing. However, I 
do notice that the file containing the commands that would make this run 
namely basic.m is in 

$SAGE_ROOT/lib/python3.7/site-packages/sage/ext_data/magma/

Does this mean that I should somehow recompile sage with a different 
SAGE_ROOT, or teach Sage to look here instead when it wants to fool around 
with magma? Any help fixing it would be appreciated. Thank you!

[sage-devel] Re: Completions of NumberFields at non-archimedean primes

[Kannappan Sampath]

Further update (after poking around) ---

Our p-adics framework already anticipates this very thing (see the function
sage.rings.padics.factory.split(poly, prec) at the end of the page linked
below) 

http://doc.sagemath.org/pdf/en/reference/padics/padics.pdf#page=46

There is a cryptic remark "We need better 푝-adic factoring in Sage before
this function can be implemented." I gather this is circa 2011, but also I
am not sure what algorithm was intended?

I have not thought about the algorithmics of this before, so I apologize if
what follows is garbage.
But looking online, it seems like Ore-Maclane algorithm or modified
versions thereof can solve this problem?
In 2013, Julian R\"uth has implemented some aspects of the OM algorithm. So
presumably we are not far off?

Thank you for your indugence and help!

   Best,
   Kannappan

[sage-devel] Completions of NumberFields at non-archimedean primes

[Kannappan Sampath]

Hello everyone ---

Does Sage already support computing completions of number field like magma
does?

In other words, given a number field H and a prime ideal P in H, return the
pair (H_P, phi) where H_P is the completion and phi: H c> H_P is the
canonical embedding.

I see that there has been recent activity implementing completions of
global function fields.
https://trac.sagemath.org/ticket/27418

I don't quite know what Sage is currently lacking in terms of actually
implementing this. (Apologies in advance if (a) is already possible!)

Thank you!


   Best,
   Kannappan

Sorry, "it" was supposed to be h(z).

Admittedly, after coercing the element into a formal power series ring, I
was able to do compute "the" formal square root of h.
For now, I think this would suffice. I have a hacky way to finish the rest
of the computation I have in mind, I think.

I will perhaps write a trac ticket with more precise description of the
functionality that would be nice to have.
Thank you for your help!

[sage-devel] p-adic analytic functions

[Kannappan Sampath]

Hello everyone --

I am trying to do the following computation ---

Suppose that h(z) is a polynomial defined over an extension of the 23-adic
integers with unit constant term h(0) and that the uniformizer divides
h(z)-h(0). "By Newton's binomial theorem", it admits a square root. I want
to be able to compute this square root.

Set aside precision issues for a moment; short of coding this by hand, are
there methods in Sage that I should be looking at? I haven't kept in touch
with the developments on Sage in the past three years and so I am not sure
what has been done.

Thank you for any pointers you might have!

   Best,
   Kannappan

Re: [sage-devel] Re: Some Magma help

[Kannappan Sampath]

Dear Simon:

Thank you for your email!

I think our definition of a lattice should be (!) identical over ZZ. But I
think that the techniques one needs to compute Hecke operators will involve
enumerating short vectors in lattices. (Moreover, the structure theory for
a finitely generated module over an arbitrary Dedekind domain, while
analogous, is presumably computationally involved.

In any case, I will be happy to take a look at the code once I am up to
speed with GIT and the trac server!

I sure would like to contribute something towards that. I am at the moment
having a couple of exams and papers to finish writing! I will get around to
this surely before my winter term begins...

It reminds me of how I should figure out how to share the translation I
already have...

I have so far been working only on the chapter 9 about polynomials...

  I guess the number of available books on Maple and
  Mathematica is a reason for some teachers to choose these languages. To
 my
  mind, it would be much more efficient (though maybe more work too) than a
  marketing document!

 The good thing is that we do not even have to chose between the two.

Hi Pablo, 

Thanks for this post. I am hoping that the proposal will garner more

 Now there is only a need for a few more questions to attain the 10 votes 
 necessary to go to the commitment phase. I believe the quality is there, and 
 it's only a matter of upvoting the better ones.

 I do hope sage can have a lot of packages like R.
 It seems that sage focus on pure mathematics more than application.I do
 not find some module such as neural network.


 This is true in Sage proper, but luckily there are many Python packages as
 well that do many applications.For example, pybrain and conx seem
 to be good things to check out.  And then you can use them within Sage as
 well as standalone.   The idea is that Sage does the mathematics and
 related packages can join modeling to it - though we would not object to
 modeling!  For instance, brian is an optional Sage package.

[sage-devel] Help defining the Sage StackExchange Proposal

[Kannappan Sampath]

Hi Sage-devel,

While the proposal on SE has been stagnant for sometime now, I think we
could atleast try and define this proposal so as to have many more people
following it and increasing the chances of this site becoming a reality.

 A proposal for all open source math softwares has been deleted for
inactivity. So, it is unlikely that such a proposal will gather momentum.
However, a restricted proposal where on-topic questions are about Sage and
its subcomponents is meatier enough.

Now, the expression Sage and its subcomponents is clunky; is there an
official term for the subcomponents? On the Sagemath page, we
write open-source packages to describe these subcomponents. So, is Sage
and its packages an appropriate expression?

Finally, Alexander Konovalov (on
http://discuss.area51.stackexchange.com/questions/14717/role-compared-to-asksage)
suggests some site names too:

1. asksage,stackexchange.com
2.sage.stackexchange.com (I don't quite like this as it confuses with that
accounting software...)

I would like to throw in:

3. sagemath.stackexchange.com

I would be glad to hear your replies...

PS. This proposal is just an experiment; for me, I am only interested in
the fact that this experiment will run atleast once (we should try to have
a centralised QA resource in view of long-term user support but the point
seems to be, do we want it on this platform) and not really on its outcome,
as I already said on the fb group for cloud.sagemath.

With Sincere Regards,
Kannappan.

Re: [sage-devel] Re: Sage Stack Exchange Site

[Kannappan Sampath]

I don't agree that we may not make a successful proposal.

* Firstly, this site, if it ever becomes a reality, will subsume
ask.sagemath.com alright, but not just that. This will help the entire
community of GAP, PARI, Maxima, Singular, Sympy (probably also R, but
cross-validated already handles quite a bit...) users... I have not written
to their sites just yet but certainly this proposal is meant as a QA for
computing in the Python ecosystem rather than just Sage. In light of this,
I am willing to believe that conservative estimates of KCrisman would
probably go up; probably more than the threshold too...

So, in my opinion, instead of being too conservative about the possible
failure, we could try and support the proposal and see if we could make
headway into getting this site created.

 Does one really need an SE site for Sage? What's wrong with
 http://ask.sagemath.org/ in your opinion then?




 The only real problem with ask.sagemath, as Kannappan says, is the
 spammers.

 Advantages:
 * Many people already have SE (e.g., mathoverflow) accounts, and these
 would be connected
 * They handle spam etc. for you
 * Could migrate questions on other SE products to this, or vice versa
 Disadvantage (for some):
 * platform itself not open-source
 Disadvantages:
 * Not connected to previous rep mechanism for ask.sagemath
 * Not connected to previous answers/questions (harder to work on dups, etc)
 * Admin privileges etc are not up to Sage
 * If the site does not get used, it will be deleted.
 * Do we own the data?  There is a CC license but is it exportable?
 * Unclear and hard (for us) to reach standards of business.

 To me, the last one is the real problem.  For instance, at one time 15
 questions per day on average is a healthy beta but we definitely did not
 always hit that even in the most halcyon days of ask.sagemath.  I'll note
 that http://area51.stackexchange.com/faq seems to have gotten rid of any
 formal requirements, but there are definitely still standards to make it TO
 beta, much less out.  Compare the graduated versus not proposals, e.g.
 http://area51.stackexchange.com/?tab=launched

 Let's see what it says.  Remember, SE is a *business* that wants to drive
 traffic.  Not first and foremost to simply have quality QA sites.  Sage
 doesn't (yet), in my view, have enough traffic to drive this.  It could!
  But it doesn't yet.

 * 15 questions per day on average is a healthy beta, 5 questions or fewer
 per day needs some work. A healthy site generates lots of good content to
 make sure users keep coming back.

 Probably we would need to increase our regular traffic (I mean compared to
 when we didn't have the anti-spam measures in place) by at least 50%.

 * 2.5 answers per question is good, only 1 answer per question needs some
 work. On a healthy site, questions receive multiple answers and the best
 answer is voted to the top.

 I would argue that with most ask.sagemath questions, we really don't need
 more than one answer per question.  But SE doesn't probably care about
 that.  And I will also point out that MANY of our questions are quite
 technical or don't ever get answers - see
 http://ask.sagemath.org/questions/?sort=answers-ascpage=6 (though to be
 fair, many of the answers to these are in comments, which SE would strongly
 discourage).

 * We recommend:
 150 users with 200+ rep
 10 users with 2,000+ rep
 5 users with 3,000+ rep

 Even on the CURRENT ask.sagemath we have about 50 with 200+ rep.  We do
 have the requisite number of very-high-rep users, and are likely to
 continue to have.  This is mainly because we don't have the critical mass
 yet - in order to really rack up reputation, you either need to answer a
 LOT of questions, or be one of the few people who answers questions
 interesting to a lot of people in the (as yet, smallish) Sage community.
  Most people who answer a question get only one or two up votes, even if
 the answer is correct.

 * 90% answered is a healthy beta, 80% answered needs some work. In the
 beta it's especially important that when new visitors ask questions they
 usually get a good answer.

 I believe I've already touched on this.  We are not currently going to be
 there.

 * 1,500 visits per day is good, 500 visits per day needs some work. A
 great site benefits people outside the community. Eventually, 90% of a
 site's traffic should come from search engines.

 I don't know anything

their mailing list...

it does not exist...

 This does sound interesting.  Is it targeted enough?  SE seems to want
 fairly well-scoped things - I don't know whether they would want something
 as broad as open source math or Python math.


Probably, this is not too broad given that computational science
stackexchange site exists. I still think we might succeed if enough of us
commit and actively request users to use the Stack Exchange site for well
focussed questions (when it becomes available). Do you think I could edit
the proposal to make it somewhat more broad in this sense. What would your
suggestion be towards that, in terms of wording it?

 Yes, that is certainly true.  One annoying thing is that on SO the sage
 tag supposedly refers to us, but I've given up trying to remove the tag
 from questions about Sagepay accounting software...  I suppose in principle
 we could ask about migration.   That would be the ideal way to approach it,
 so as to keep things in one place.

 Also, as a counter to my point about staying OSS, both Ubuntu and Drupal
 host their question/answer on SE, one even with its own domain
 http://askubuntu.com/ - so this isn't a killer to other such communities.
  But it should be raised, anyway.

Re: [sage-devel] docbuild getting stuck

By stuck I mean that I run make and

 while there are python processes like this:

 make doc-clean does not help.

 This must be a bug in sphinx, IMHO...

Re: [sage-devel] Create a branch without a ticket

Hi,

I have been under the impression that sage dev scripts are being dropped in
favour of git-trac subcommand for git available from
https://github.com/sagemath/git-trac-command.

HTH,

[sage-devel] Docs not building on 6.2

[Kannappan Sampath]

Hi group:

I have been trying to build the doc for SAGE 6.2 on a Mac OSX 10.9.2. The
doc build always stops at:

[tensor   ] writing output... [ 75%] sage/tensor/differential_form_element

[tensor   ] writing output... [100%] sage/tensor/differential_forms

[tensor   ] dumping object inventory... done

[tensor   ] build succeeded.


^Cmake: *** [doc-html] Error 130


(emphasis above is mine; that is the response to my C-c)


And, I press C-c and terminate the thing after a couple of minutes... I do
make doc-clean and make doc again and the same thing repeats!

Any help would be appreciated.

p/s/ I saw that there was another thread about this problem but did not
have any solution that applied to my case (or so it appeared that way to
me!).

With Sincere Regards,
Kannappan.

Re: [sage-devel] Tracking a git branch

But everytime I need to update, I will have to do

$ git pull trac develop

while if I set the default remote branch to trac/develop or something
like that, I could just say:

$ git pull

while in the branch, right?

Am I missing something, in that, there is something called tracking a
remote branch as described in Tracking Branches section here:

 I think it should be easy to fix, as GAP can do it almost instantly (GAP

 (No kash or cash needed :-))

 sage: gap_console()

 This would need optional database_gap package installed.
 (i.e. do sage -i database_gap on the terminal).

Agreed!
 
 
 Also, probably, we should have a generic implementation of block design,
 where one gives us the point set, the blocks but is interested in computing
 parametric things with it; or computing the derived design and so on... (This
 is done in Designs package in GAP, so may be we should just borrow it!)
 
 Well, once more I never needed any of those but I would be glad to
 review it. What I like is to implement new constructions :-P
 I lve constructions.
 
The thing is, it may be very useful for someone who has figured out how to 
construct new t-designs for example. 

 GIT again is the barrier! :-(
 
 Well, it becomes rather easy very quickly... And there is a wealth of

Thank you all for suggesting that I take a look at GIT. I think I feel
better now. But, still I have gotten some questions. I am trying to review
16091.

I have checked out the ncohen's 16091 branch and have it as a local branch.
I would like to now let sage now that there has been a change in its code
due to this branch. I assume this means I run sage -b. Is this correct?

Will this let sage know that there has been a update of code?

[sage-devel] An Embarrassing Bug?

[Kannappan Sampath]

Hello group, 

I think this is probably an embarrassing bug:

def IncidenceStructureFromMatrix(M, name=None):

Builds and incidence structure from a matrix.

INPUT:

- ``M`` -- a binary matrix. Creates a set of points from the rows and a
  set of blocks from the columns.

EXAMPLES::

sage: from sage.combinat.designs.block_design import BlockDesign
sage: BD1 = 
BlockDesign(7,[[0,1,2],[0,3,4],[0,5,6],[1,3,5],[1,4,6],[2,3,6],[2,4,5]])
sage: M = BD1.incidence_matrix()
sage: BD2 = IncidenceStructureFromMatrix(M)
sage: BD1 == BD2
True

nm = name
v = len(M.rows())
b = len(M.columns())
#points = range(v)
blocks = []
for i in range(b):
B = []
for j in range(v):
if M[i, j] != 0:
B.append(j)
blocks.append(B)
return IncidenceStructure(range(v), blocks, name=nm)


The problem is with the indexing if M[i, j] != 0. Of course, this will not be 
a problem for square 2-designs like the Hadamard design or 
ProjectivePlaneDesign (thanks to Fisher Type counting), but this should cause 
problem for designs that are not square. I was bitten by this bug when I tried 
to implement Hadamard 3-design from a Hadamard matrix. 

I will open a ticket if somebody does a sanity check for me. 

With Sincere Regards, 
Kannappan.

 Well, OK. My fault. Pass any non-square 0, 1 matrix to it and you would
see: for example,

IncidenceStructureFromMatrix(Matrix(ZZ, 2, 3, [1]*2*3))


 If you do correct it please change

 If you correct the code, please provide a piece of code that does not
 work with the current implementation (otherwise, it can not be
 considered as a bug).

 Well, OK. My fault. Pass any non-square 0, 1 matrix to it and you would
 see: for example,

 IncidenceStructureFromMatrix(Matrix(ZZ, 2, 3, [1]*2*3))


Sorry, actually:  IncidenceStructureFromMatrix(Matrix(ZZ, 3, 2, [1]*2*3))

  If you do correct it please change
 {{{
 v = len(M.rows())
 b = len(M.columns())
 }}}
 by
 {{{
v = M.nrows()
b = M.ncols()
 }}}


 Will do!

   Hello group,
  
   I think this is probably an embarrassing bug:
  
   def IncidenceStructureFromMatrix(M, name=None):
   
   Builds and incidence structure from a matrix.
  
   INPUT:
  
   - ``M`` -- a binary matrix. Creates a set of points from the
 rows
  and
   a
 set of blocks from the columns.
  
   EXAMPLES::
  
   sage: from sage.combinat.designs.block_design import
   BlockDesign
   sage: BD1 =
  
 BlockDesign(7,[[0,1,2],[0,3,4],[0,5,6],[1,3,5],[1,4,6],[2,3,6],[2,4,5]])
   sage: M = BD1.incidence_matrix()
   sage: BD2 = IncidenceStructureFromMatrix(M)
   sage: BD1 == BD2
   True
   
   nm = name
   v = len(M.rows())
   b = len(M.columns())
   #points = range(v)
   blocks = []
   for i in range(b):
   B = []
   for j in range(v):
   if M[i, j] != 0:
 
 
  As I tried to explain, the indexing is ballsed up: v is the number of
 rows,
  b is the number of columns. Since i is in range(b), i is a column index
 and
  similarly, j is a row index. So, the code should have looked at M[j, i]
 as
  opposed M[i, j] in the if condition.
 
  Kannappan.
 
   B.append(j)
   blocks.append(B)
   return IncidenceStructure(range(v), blocks, name=nm)
  
  
   The problem is with the indexing if M[i, j] != 0. Of course, this
   will
  not
   be a problem for square 2-designs like the Hadamard design or
   ProjectivePlaneDesign (thanks to Fisher Type counting), but this
 should
   cause problem for designs that are not square. I was bitten by this
 bug
  when
   I tried to implement Hadamard 3-design from a Hadamard matrix.
  
   I will open a ticket if somebody does a sanity check for me.
  
   With Sincere Regards,
   Kannappan.

Re: [sage-devel] Hadamard Designs

[Kannappan Sampath]

Hi Nathann, 

On Apr 22, 2014, at 6:44 PM, Nathann Cohen nathann.co...@gmail.com wrote:

 Y !!
 
 But, of course, this design extends uniquely to a (necessarily) 2-(4n, 2n, 
 n-1) design: the blocks of this design are blocks of the old design union a 
 new point infinity and complements (in the old point set) of the blocks of 
 old design. And, any contraction is isomorphic to a Hadamard 2-design we 
 started off with. So, unsurprisingly, this family is called Hadamard 
 3-designs. 
 
 As you see, implementing the 3-design is trivial but we should settle down on 
 the nomenclature! 
 
 I did not know about this construction, but the Handbook agrees with you, so 
 why not ? :-D
 
 By the way your proof of it is very cool.
 
 So, what do you guys think? 
 
 Do you feel like creating a ticket and writing this patch ? I will be glad to 
 review it quickly. 
 

Sure, I can do this if someone would help me with GIT. I have been keeping away 
from SAGE mainly for this reason!  Anyway, I created the ticket: 
http://trac.sagemath.org/ticket/16211. 

And, we still have not thought about the nomenclature... :-) May be change the 
Hadamard design to HadamardTwoDesign and implement these as 
HadamardThreeDesign? 

Also, probably, we should have a generic implementation of block design, where 
one gives us the point set, the blocks but is interested in computing 
parametric things with it; or computing the derived design and so on... (This 
is done in Designs package in GAP, so may be we should just borrow it!)  

 p/s/ Thanks Nathann for implementing the combinat.designs! I am a big fan of 
 designs and it is nice to have them in SAGE. 
 
 Well, I am pretty glad that you noticed the changes and that you like them. 
 If you have time to review some code, there are a couple of things that are 
 still waiting on the trac server :
 
 A straightforward one : http://trac.sagemath.org/ticket/16091
 A more interesting one : http://trac.sagemath.org/ticket/15310
 
GIT again is the barrier! :-( 

-Kannappan. 

 (Vincent just reviewed http://trac.sagemath.org/ticket/15431 )
 
 The second one is a very interesting recursive construction that I need to 
 add the general construction of BIBD with k=5 (which already works on my 
 computer). There will also be a need for a patch that just cleans the code in 
 between before that.
 
 Well, this just to say that if you feel like getting your hands dirty for 
 Sage's designs... ;-)
 
 Have fn !
 
 Nathann

Re: [sage-devel] Difficulty with Galois group

Also, I am not sure whether there is  a practical algorithm to compute the 
Galois group when the extension is not normal (for splitting fields, there is 
one due to Susan Landau; however there are mod p techniques too)!

 Pathetic...
 Is it really so hard to implement, having the library of permutation
 groups at hand (from GAP)?
 The hard part is the number theory, not the group theory. If the 
 splitting field is very large (that seems to be the case here), then how 
 would you represent elements of the Galois group?
 I am pretty ignorant about the way(s) these elements become available 
 in this setting. 
 The most economic way I know offhand involves generators and relations
 (either in the classical combinatorial group theory sense, or in the
 sense of vector enumeration - when the action is defined locally
 on a module).
 Matrices or permutations aren't often too bad either - depends upon
 the sparsity.

[sage-devel] sage -dev diff

Hello group, 

I am trying to review the ticket 16091. I did 

sage -dev checkout --ticket 16091 

and I now have a new branch ticket/16091. When I do sage -dev diff, however, I

Re: [sage-devel] Re: sage -dev diff

[Kannappan Sampath]

I also need more git hand holding: I am trying to attach some code from my 
local branch to a ticket. I did the following: 

Apples-MacBook-Pro:combinat apple$ sage -dev checkout --ticket 16211
On ticket #16211 with associated local branch ticket/16211.

#  Use sage --dev merge to include another ticket/branch.
#  Use sage --dev commit to save changes into a new commit.

Now, I tried to push by sage -dev push and the whole thing fails miserably! :-( 

I would be very grateful for any help about how I would go about this... Also, 
in the older days, when I made changes to the source code, to get SAGE to know 
about it, I used to commit and build. Now, that is not sufficient? How do I get 
SAGE to know the changes I have made. 

With Sincere Regards.

Re: [sage-devel] Difficulty with Galois group

[Kannappan Sampath]

Hah, nice catch! I did not try either of them and that helps find out more: 

Apples-MacBook-Pro:~ apple$ sage --kash
/Users/apple/sage/local/bin/kash: line 4: ./kash3: Bad CPU type in executable

I get the above. I am using Sage Version 6.2.beta7, Release Date: 2014-04-08. 

So, how do I proceed with this one.

Here is Kash Log:

 Seems you don't have an option (other than that or changing the OS):
 
 In README, they say:
 
 /*** INSTALLATION ** INSTALLATION ** INSTALLATION /
 
 To make your life easier we provide binaries of the shell. At the
 moment we are supporting the following architectures:
 
 o  Linux on x86
 o  Mac OS X on PPC
 o  MS Windows 2000/XP on x86
 
 For the above architectures you have to download the corresponding file:
 
 KASH3-Linux--MM-DD.tar.bz2
 KASH3-Darwin--MM-DD.tar.bz2
 KASH3-Windows--MM-DD.zip
 
 
 And indeed:
 
 $ lipo -detailed_info kash3
 input file kash3 is not a fat file
 Non-fat file: kash3 is architecture: ppc
 
 
 Doesn't seem they've meanwhile disclosed the source code, but I don't really 
 know.
 
 I think Kash has code in common with Magma, and for that reason, I assume it 
 won't appear in public anytime soon.
 
 Also, I believe that, while Kash will run on earlier versions of x86 Macs, it 
 won't run after 10.6(?).  Isn't that the last release to support Rosetta? 
 Kash is PPC only for Macs, and there doesn't seem to have been much activity 
 there for a while (years).

[sage-devel] Hadamard Designs

[Kannappan Sampath]

Hello group!

At the moment in sage-6.2.beta7, in designs.HadamardDesign, we have
implemented the Hadamard 2-design with paramters 2-(4n-1, 2n-1, n-1) one
gets from a Hadamard matrix of order 4n.

But, of course, this design extends uniquely to a (necessarily) 2-(4n, 2n,
n-1) design: the blocks of this design are blocks of the old design union a
new point infinity and complements (in the old point set) of the blocks of
old design. And, any contraction is isomorphic to a Hadamard 2-design we
started off with. So, unsurprisingly, this family is called Hadamard
3-designs.

As you see, implementing the 3-design is trivial but we should settle down
on the nomenclature!

So, what do you guys think?

p/s/ Thanks Nathann for implementing the combinat.designs! I am a big fan
of designs and it is nice to have them in SAGE.

 Hello group,

 I realised that extended GCD for several integers is not implemented in
 Sage (i.e. xgcd2([a1, ..., an]))

 Actually this feature already exists in Magma :

  ExtendedGreatestCommonDivisor([385, 231, 165, 105]);
 1 [ -2, 1, 2, 2 ]

 It could be interesting to have something like :

 g, u = xgcd2([a1, ..., an])

 with u such that :

 a1*u1 + ... + an*un = g

 Do you think a new ticket could be posted?

 Thanks,

[sage-devel] ATLAS on Mac

I may be very ignorant here, but if my reading is right, this is weird. Can

we just not download ATLAS at all by default?

I am writing to ask you about the possibility of implementing GL(n)Pack [1]

ask about what features of Mathematica that are/were absent in SAGE that
made writing GL(n)Pack on Mathematica easier.

Re: [sage-combinat-devel] Fast Implementation for Character Values of Symmetric Groups

 Dear Darij,

 Thanks for the explanation. This is very elegant. I think it would be
 worth adding also the recursive Murnaghan-Nakayama formula to
 sage/combinat/partition.py (it shouldn't be hard for someone who knows
 their way around partitions - one needs to find enumerate hooks of a
 certain size and remove them). Let me start by puttin up a ticket. If no
 one does it right away, I will get around to it one of these days.


This does not look hard. I'll try to put up a patch!

 Hi Amri,

 Oops, I made a mistake: it should be s(p[la]), not p(s[la]). Sorry!

 Generally, any basis of Sym is implemented as a *ring in its own*. So
 when you write p(s[la]), it understands compute the Schur function
 corresponding to partition la, and then convert it to the power-sum ring.
 And once it's in the power-sum ring, coefficient means coefficient of
 the corresponding power-sum symmetric function, not coefficient of a
 monomial (actually, the computation I suggested never goes through
 considering monomials).

 But you are right in saying that this is not an optimal solution, and it
 might be better to implement the Murnaghan-Nakayama rule directly as a
 hook-removal algorithm rather than by building the whole s and p bases of
 Sym. If you want to change this, I'd say the best place to do it would be
 sage/combinat/partition.py.

   Best regards,

 Dear All,

 As most of you probably know, there is a mailinglist 
 sage-trac-accounthttps://groups.google.com/forum/#!forum/sage-trac-account.
 The purpose for this mailinglist is to distribute the task of creating trac
 accounts among several sage devs, so that people needing a trac account wil
 receive one in a timely fashion. However the number of people actively
 creating accounts has dropped, causing potential new sage devs to get their
 trac accounts later then desired. So I'm now asking if there are people
 that would like to help by creating an account say once a week (takes about
 5 min).

 The reason the creation process is manual is because the captcha of trac
 is not strong enough so our trac server will get spammed with useless
 messages about certain medicines if we made the process automatic as used
 to happen in the past.

 If you are interested in helping out please send a message either to me or
 to the sage-trac-account mailinglist.

 Thanks,
 Maarten

 Hello,

 I'm a new user of Sage and I had some difficulties to find the Sage
 command-line options.
 I tried sage -h, that worked, and then I could find the sage -advanced
 command that printed what I was looking for.
 But it would be better if Sage had a man page, that could be found with
 man sage.
 Thats's why I adapted the advanced help message to a man page, which is
 joined to this message. I hope that it would be useful.

 Regards,

 YMADEC


 P.S. Sorry for my bad english, I'm just a young french student...
 I also could help translating Sage, if needed.

 At least in theory, each category is supposed to provide an example.
 And the category of finite enumerated sets is no exception:

   sage: E = FiniteEnumeratedSets().example()
   sage: E
   An example of a finite enumerated set: {1,2,3}
   sage: E.__module__
   'sage.categories.examples.finite_enumerated_sets'

 So, you can find the code in SAGE_ROOT/devel/sage/sage/categories/

 And of course, you can also see the code by E??.

 Upgrading *from* betas / rcs is only (again) supported since Sage 5.9.beta4,
 i.e., you'd need some stable 5.8 (or probably stable 5.7, or 5.9.beta4+)
 version to upgrade from.

 But the final 5.10 will (hopefully) get out soon anyway (although you could
 upgrade from 5.10.rc1, say, later, too).


 I'd recommend building 5.10.rc1 from scratch (and upgrading /that/ later)
 though... ;-)

Re: [sage-combinat-devel] Re: Longest element in a Coxeter Group - name decision

Hello!

That was very enlightening. I haven't been able to come back to this
because of the exams. So, let me summarise the changes we have agreed to
make:

(1) Move the method in question, long_element to the Coxeter Groups
category.
(2) Deprecate this method and redirect the user to longest_element method,
which should be decorated with a warning: that this method might not
terminate for infinite groups.

Did I get this right?

delay.

 Yes, we will definitely want some automatic type recognition at some

 Now, for the problem at hand, I guess that's overkill. Let's write in
 the specs, as a big fat warning, that the function will only terminate
 if the (parabolic sub) group is finite. And add some simple and fast
 sanity checks in the easy to handle cases. Something like:

 def longest_element(index_set=None):

[sage-combinat-devel] Longest element in a Coxeter Group - name decision

[Kannappan Sampath]

Hello friends,

I am writing this mail to ask for your help in a naming decision.
In the file sage/categories/finite_coxeter_groups.py, there is a function
called long_element. The docstring asks if this should be renamed and if
so, to what?

There are two suggestions from the authors: longest_element,
maximal_element.

Now, I think longest_element is pretty common. But, LiE, Marc's Lie Group
computation software seems to call this `long_word()`.

1) what should we pick?

2) I started a ticket to clean up this file on trac:
http://trac.sagemath.org/sage_trac/ticket/14050

I understand that name changes are to be handled with care. How do we go
about this one? Deprecate?

With Sincere Regards,
Kannappan.

 Hello friends,

 In the file sage/categories/finite_**coxeter_groups.py, there is a

 There are two suggestions from the authors: longest_element,
 maximal_element.

 Now, I think longest_element is pretty common. But, LiE, Marc's Lie

[sage-devel] Sage FAQ

[Kannappan Sampath]

In the Sage FAQ, Release 5.7, we have this:

2.9 I used Debian/Ubuntu to install Sage 3.0.5 and that version is giving
lots of errors. What can I do?


But, if I am not mistaken, Sage 5.6 is available from the Ubuntu Repos and
Sage 5.7 should be available as usual too...


Am I missing something?

[sage-devel] Good Manners?

[Kannappan Sampath]

Hello!!

Is it considered good manners to change the status of a (needs_review)
ticket to sth else (of course, other than giving (positive_review)) when
you are not the reviewer, but the reviewer has left some comments
indicating some work to be done or asking for some more information about
the patch?

I am asking this because, there are a couple of tickets, which are
obviously not those that need_review (they either needs_work or
needs_info).

Thank you.

 I'd say yes. If some comment can be interpreted as needs_work, then it's
 okay to set the status to needs_work.

  Hello everyone,
 
  I would be very glad if someone can please help me with this problem. I
  had wanted to review some doctest-adding patches. So, as a preliminary,

 I think we need more information about exactly what you're trying to do.
 1) was this a build from source or a binary build?

2) do you get the same errors with a plain vanilla Sage (without the
 extra patches)?
 3) does the sage executable refer to the version of Sage you're testing?

I think no: the sage --version echoes Sage 5.6 that I got from Ubuntu
Repos!! And, I had applied the patches for testing on sage.5.7.beta4.

4) did you remember to run sage -b after applying the patch?

Yes.

So, could you please tell me how would I run this version of sage? And, I
think the reason the tests are failing on the Sage 5.6 is there are some
changes that I have not committed. Is this right?

Thanks for the hint that the sage test works from any other directory. But,
if I did sudo, the sage says, some other users could put files and is not
the best place to run sage code from, which makes sense.

Hopefully, I have given enough information to help me.

Thank you.

[sage-devel] Doctesting quadratic_form__automorphisms.py

[Kannappan Sampath]

Hello!!

On Sage 5.7.beta2, all doctests in the file in question pass. But, for some
reason, on 5.7.beta3 and beta4, the process gets killed because of time
out!

Could someone please tell me how to handle this one? Are there flags that
can override time outs in doctests?

Kannappan

 There are environment variables SAGE_TIMEOUT and SAGE_TIMEOUT_LONG. You
 might also run with --verbose to see precisely where it timeouts.


Thanks for the pointers. I tried the verbose command. Here's something
strange happening: there is a  failing example but, when I try on Sage, I
do get what the docstring says. Let me paste the relevant part of the

This timeout I think is because Sage is unable to figure out where this

Any pointers would be very helpful.

 Sorry, in the beta releases of sage 5.7, clear clears the screen. As P

 Dear Colleagues,

 I just want to point out that at least one of the results of the

 Matrix Multiplication in Sage vs. MATLAB and Mathematica.

 On my personal, quite old, with a Celeron 3Ghz, 2 core machine, 64 bits, I
 get:

 752 ms
 which is very far from the result on the web site:
 3.28 s per loop.

 The very impressive performances of Atlas is: 1.06100795755968e10 flops.
 As the matrix is large, Atlas use 2 threads, and this gives
 5.30503978779841e9 flops by core, which is what can be expected with such a
 processor.

 Ok, this will be certainly much better with a more modern processor, but I
 think nowadays, no processor will take 3.28 second...

[sage-devel] Clearing the Terminal when running Sage

[Kannappan Sampath]

Hello!

Sage versions: 5.6, 5.7beta3...

I'd be glad if someone can help me here: I'd like to clear the terminal
sometimes when I run Sage.

-- For instance on Octave, Ctrl + L works [1]. Here is what surprises me:
in the Octave interface that Sage provides, this simply does not work!!

I don't understand what clear does on Sage. Could someone elaborate?
In my attempts to understand this, clear? brings an help which I don't
understand. After defining a = 5, both clear(a) and clear('a') complain:
NameError clear is not defined...

Not sure, what is happening!!

I am ccing the sage-devel in case they may have anything to say.

[1] clear does not do what it is intended to do: in Octave, it simply
clears the namespace, so all the variables go undefined.

Thank you first for the reply...

True! I'll reply in this thread with a couple of tickets that my eye
catches. I am particular about having a very clean Trac and hence I am
going through various tickets to see if I can do sth about. This jsMath
stuff is a bit too technical for me to handle and hence posted here...


 I would like to bring to people's notice the following: we have a couple
 of jsMath related tickets. That we have shifted over to MathJaX for the
 notebook interface, are these at all relevant? Some of the meta things --
 yes, but specifics about jsMath, may not be. Should we clear these tickets?

[sage-devel] Some Old Tickets

[Kannappan Sampath]

Hello friends,

I would like to bring to people's notice the following: we have a couple of
jsMath related tickets. That we have shifted over to MathJaX for the
notebook interface, are these at all relevant? Some of the meta things --
yes, but specifics about jsMath, may not be. Should we clear these tickets?

And, I found an amusing ticket here... but IMHO, time has now come to set
the milestone to sage-invalid... since the claim of the ticket is really
invalid. :)

http://trac.sagemath.org/sage_trac/ticket/2048


Have a nice week ahead!

Here's a recent one that I know of that does this:

to know if there are better ways of doing this, than what is done here.

 Having a feature like this will make embedding worksheets way more
 natural, so kudos to whoever polishes this and puts it into production.

 Almost every object in sage can return latex output. I think that the

 For example,

 sage: latex(CyclicPermutationGroup(**5).character_table())
 \left(\begin{array}{r}
 1  1  1  1  1 \\
 1  \zeta_{5}  \zeta_{5}^{2}  \zeta_{5}^{3}  -\zeta_{5}^{3} -

 1  -\zeta_{5}^{3} - \zeta_{5}^{2} - \zeta_{5} - 1  \zeta_{5}^{3} 
 \zeta_{5}^{2}  \zeta_{5}
 \end{array}\right)

 Here the output should clearly be typset in math-mode but as far as I
 can see python doesn't know this.


 It is typeset here alright. http://i.imgur.com/UEvj3.jpg
 Do you have typeset checked? Otherwise you need to do either
 view(latex(...)), or pretty_print(latex(...)), or even just view(...) and
 pretty_print(...).


While we are at this, let me mention that the way latex() handles operation
tables of algebraic objects needs to be fixed. There are a couple of
tickets on this theme:

1.  http://trac.sagemath.org/sage_trac/ticket/11362
2. http://trac.sagemath.org/sage_trac/ticket/10787

I am willing to work on this ticket if someone will give me some pointers.

 Thanks for confirming this John. I had trolled through the code this
 morning and thought that this was the case, so it is good to know.

 In almost all cases, I think that the output of latex is intended to be
 typeset in maths mode so I'll make this the default but will allow an
 override.

 @kannappan The main idea behind the code I am writing is to provide a
 better way for viewing, and
 accessing the entries of, large (labelled) tables.

Andrew, does this mean, that your patch when ready will actually take care
of the tickets mentioned?

[sage-devel] Patch made from a previous version of sage

[Kannappan Sampath]

Hello friends,

I have the following question: The patch here:

http://trac.sagemath.org/sage_trac/ticket/10080

seems to come from a previous version of the file for which it proposes
some change. Now, apparently, I feel that some of the issues have been
resolved, by  a new revision to that file. (I looked at the way
documentation looks for this particular case...)

How is this situation usually handled?

Re: [sage-devel] Re: Normalization of a vector

Here's a natural place where I can see this is helpful:

To carry out, Gauss-Jordan like row reductions, where you'd like the first
non-zero entry in a row (the so-called pivot) to be 1, I think this is very
helpful.

So, I'd be **for** keeping this, perhaps in a different name, that would
reflect this. Like `reduce(v)` or perhaps, `echelonize(v)` for instance.

 undergrads and found it frustrating that Sage was not doing the standard

Perhaps, I should explain my rationale for the terms I chose, my first
preference is `echelonize(v)`  (although I wrote it second) because, what
the function returns amounts to its reduced row echelon form, if you think
of it as 1 x n matrix.
