This is great news! Is there any plan to implement semaphore codes in the near future (see the book by Jean Berstel , Dominique Perrin , Christophe Reutenauer

Re: [sage-coding-theory] Re: [sage-devel] Re: 2-year project with full-time software developer for improving coding theory in Sage

About dependencies (again): Working with Vincent on Combinatorial Designs (many tickets between beta releases) taught us that it is better to 'artificially' order all tickets linearly. Each ticket should have a successor and a predecessor, and they should all be linearly ordered. It is tempting to

Re: [sage-coding-theory] Re: [sage-devel] Re: 2-year project with full-time software developer for improving coding theory in Sage

Hello ! > Agreed. great news! Indeed. I do not know if what you have in mind about coding theory somehow overlaps with combinatorial designs (in particular orthogonal arrays/BIBD :-P) but it would be nice to shake those areas of Sage anyway. >>> Of course, all code will go through the Trac and t

[sage-devel] Re: Code fails on SECOND attempt only... please help!

I guess caching is causing that. Creating ProjectiveSpace twice with the same input creates two projective spaces that are equal (P==Q) but not identical (P is not Q). Caching will look at "==" so if you compute something on the second projective space then you might get back something from the

[sage-devel] Code fails on SECOND attempt only... please help!

In the midst reviewing ticket 16986, my reviewer came up with the following example that fails: R.=PolynomialRing(QQ) K.=NumberField(z^3+2) R.=PolynomialRing(K) L.=K.extension(t^2+t+1) P.=ProjectiveSpace(L,1) H=End(P) f=H([x^3-2*y^3,v*y^3]) f.rational_preimages(P([0,1])) However, when I run it o

That is great news AFAIK, there is still some code from last year's GSoC which is not merged, so maybe it is a good oportunity to retake that (ticket #14973) El miércoles, 15 de octubre de 2014 17:22:40 UTC+2, Johan S. R. Nielsen escribió: > > Hi sage-devel > This is to announce and get s

[sage-devel] Re: KASH and polynomials of degree 22 and 23

KASH/KANT hasn't been maintained since about 2008 or something like that. I think you are pretty unlikely to get a response from their email address. However, I think I hear the voice of one of the former maintainers going into his office just down the hall from me. I'll ask him. If he says any

[sage-devel] 2-year project with full-time software developer for improving coding theory in Sage

Hi sage-devel This is to announce and get some feedback on the start of a Sage software-development project. This spring, Daniel Augot, Clément Pernet and I got funding from INRIA for hiring a full-time software developer for two years to work on extending the coding theory functionality in Sag
