The account creation page only takes seconds to load instead minutes. So this new server makes me very happy. Le lundi 22 avril 2013 20:19:44 UTC+2, R. Andrew Ohana a écrit : > > Hey Everyone, > > Sometime in the next couple weeks, we will be moving our trac installation > over to a dedicated VM

Re: [sage-devel] Univariate quotient ring returning wrong results

+1 It's better to raise an error then to fail silently. If it turns out that a lot of doctest break because of this change it is maybe good to instead create a method called reduce_unique, or add a keyword unique to reduce. Here reduce_unique should have the additional property that I.reduce_u

[sage-devel] How to automatically download the newest sage?

Dear all, I want to create a script that when I run it automatically downloads the latest sage developement version. I was wondering what would be the best way to do so? Thanks Maarten -- You received this message because you are subscribed to the Google Groups "sage-devel" group. To post to

Re: [sage-devel] Re: Graph neighbours - room for huge performance boost

I decided to do some profiling. And there is something that worries my slightly more then the factor +/-10 difference in iteration speed that caused the start of this topici. Namely conversion from a sparse sage graph to a networkx graph seems to have quadratic runtime complexity instead of l

[sage-devel] Re: Graph neighbours - room for huge performance boost

As mentioned on the ticket it might be good to still post your "broken" patch. Not every patch needs to be perfect the first time. By posting your code it is easier for people to see exactly what is broken by your faster code (probably it is because there are some functions that directly modify

[sage-devel] Re: why is email in sagenb?

I've heard quite often now for several things that if something is needed in both sage and sagenb then we will need two copies. If there are really multiple cases, then maybe it is time to make a small python library called something like "sage-utilities" that contains all the functionality that

Re: [sage-devel] Sage doctesting on shared systems insecure (#13579)

Maybe it can be fixed by using: from __future__ import absolute_import I at least know that python 3 fixed some issues caused by relative imports. But I'm not 100% sure if this problem is also solved. Le mercredi 10 octobre 2012 14:14:22 UTC+2, Jeroen Demeyer a écrit : > > On 2012-10-10 13:59,

[sage-devel] Re: can't recover user password

I have the feeling that it might be due to the new flask notebook that got merged in 5.2 (see http://trac.sagemath.org/sage_trac/ticket/11080) this changed a lot of login related things. Le mercredi 19 septembre 2012 13:29:02 UTC+2, mmarco a écrit : > > I have set up a sage server with several

Thanks for the report. This seems to be a bug indeed. Do you have a trac account and are you willing to upload a patch to trac.sagemath.org? Also can you tell us wheter this bug is reproducable and how you triggerd it? This will be usefull for writing a small test that ensures it will not get b
