[sage-devel] Sage forker

2011-01-14 Thread Jeroen Demeyer
This afternoon, William gave me a really cool idea of starting up Sage using fork(). Essentially you have one mothersage which forks off copies of Sage. Like this, you can get an instant Sage prompt because Sage is already started. I actually implemented this and it seems to work (at least under

Same (broken) behavior here. Firefox on Ubuntu 10.04 with Javascript enabled. Sage 4.6.1.alpha3. Warning also results when I try the same search function at the Table of Contents for the Reference Manual, so it seems systemic. Rob On Jan 14, 12:44 pm, John Thurber wrote: > thoughts?  Is this

2011-01-14 Thread asd1815
I am aware of that's why I pasted it in there. Why would you package something and label it with "Fedora13 release" when it wasn't even linked with default libraries fedora comes with? I am using what the package said it needs. The package either needs to be fixed. Or someone should put a pre-req

the binary release you are using apparently needs GLIBCXX_3.4.14, and you have an older version (GLIBCXX_3.4.13) On Jan 13, 8:29 pm, asd1815 wrote: > I am running Fedora 13 with all updates applied. ... -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from

Sounds like you want to reinstall the spkg with sage -f -s (keep build) and LDFLAGS=-g. Though that depends a bit on how broken the source build system is. -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubsc

[sage-devel] Re: about karatsuba multiplication for polynomials over generic rings

2011-01-14 Thread rjf
For a discussion of practical fast polynomial multiplication, see http://www.eecs.berkeley.edu/~fateman/papers/dumbisfast.pdf and also the first reference in that paper. (As well as other references). The code in GMP is likely to be well thought out. You are probably making a major mistake setting

[sage-devel] how to gdb code in an spkg?

2011-01-14 Thread Dima Pasechnik
Is there any standard way to force .o (and .c) files be be installed and available to the debugger run by "sage -gdb" ? Or at least any spkgs which have such an option built-in, from which this can be lifted off? Thanks, Dima -- To post to this group, send an email to sage-devel@googlegroups.co

[sage-devel] #1819

2011-01-14 Thread Martin Albrecht
Hi, I've attached a patch to the ticket http://trac.sagemath.org/sage_trac/ticket/1819 which moves mq.MPolynomialSystem to sage.rings.polynomial.multi_polynomial_sequence as PolynomialSequence. If someone has some time to spare to review this patch that'd be very much appreciated since Al

[sage-devel] about karatsuba multiplication for polynomials over generic rings

2011-01-14 Thread luisfe
I have rewritten the karatsuba algorithm for Polynomial_generic_dense_field. The code needs some cleaning, but it is already usable at #10255 My primary personal motivation is that, for number fields as base rings, karatsuba performs worse than the generic multiplication. For this concrete problem

[sage-devel] Re: Advice for "Lazy" Symbolic Evaluation

2011-01-14 Thread Chris Swierczewski
Does anyone know of an example where a class __call__ method takes lists as input? (With possible symbolic entries, of course.) I'm attempting to follow the structure of Function_sec (and similar functions) but when I try sage: var('x') sage: theta([x,x^2,x^3]) I get the following error: Trace
