(Are you a Sage developer? Should I consider the bug reported?) 2011-08-15 15:30:28 +0200 asked a question bug in minimal polynomials of finite fields In a compiled version of 4.7 (64 bit, Debian Sid), I get:  ---------------------------------------------------------------------- | Sage Version 4.7, Release Date: 2011-05-23 | | Type notebook() for the GUI, and license() for information. | ---------------------------------------------------------------------- sage: F.=GF(2^64) sage: a.minpoly() _3 = x^64 + x^33 + x^30 + x^26 + x^25 + x^24 + x^23 + x^22 + x^21 + x^20 + x^18 + x^13 + x^12 + x^11 + x^10 + x^7 + x^5 + x^4 + x^2 + x + 1 sage: K.=GF(2^128) sage: b.minpoly() _5 = x^128 + x^7 + x^2 + x + 1 sage: a.minpoly() _6 = x^128 + x^7 + x^2 + x + 1  Is this a bug or am I doing something stupid? Thanks, Luis 2011-05-31 13:54:46 +0200 commented answer Fedora 14 binary Thanks. I've compiled it from source successfully. 2011-05-27 11:48:59 +0200 asked a question Fedora 14 binary Dear all, I just installed sage-4.7-linux-64bit-fedora_release_14_laughlin_-x86_64-Linux.tar.lzma on my computer running Fedora 14: boole[~]$uname -a  Linux boole.math.utk.edu 2.6.35.12-90.fc14.x86_64 #1 SMP Fri Apr 22 16:01:29 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux But I'm getting the following error: ImportError: /usr/lib64/libstdc++.so.6: version GLIBCXX_3.4.15' not found (required by /work/local/sage-4.7/local/lib/python2.6/site-packages/sage/rings/finite_rings/element_givaro.so) Error importing ipy_profile_sage - perhaps you should run %upgrade?

Thanks, Luis 2011-03-29 16:46:10 +0200 commented answer no linewidth with parametric plot Thanks. That works (of course). It is too bad that the syntax is not uniform... 2011-03-28 18:42:17 +0200 received badge ● Organizer (source) 2011-03-28 18:41:32 +0200 asked a question no linewidth with parametric plot It seems that there is no option for linewidth in parametric_plot. (2D in my case.) Is that true? Any way to make the graph thicker? 2010-11-08 20:18:39 +0200 received badge ● Supporter 2010-11-05 17:50:53 +0200 commented question compilation problem: 4.6 on Fedora 11 Thanks Evgeny.
