[sage-devel] Volunteers for a Sage presentation/tutorial at CARI 2014?
Hello, The upcoming CARI 2014 African Conference on Research in Computer Science and Applied Mathematics will occur in Senegal next October. Would anyone be interested in presenting Sage (20-23 October) or organizing a tutorial (16-18 October)? The submission deadline is January 31st. http://www.cari-info.org/index.php?option=com_content&view=article&id=85&Itemid=64 The delay is short, but maybe the organizers would accept a preliminary project description. I got the information from my dad who is likely to be there to present his regular booth on open source scientific software; he further mentioned that the local Dakarlug mailing list is very active. Some other food for thoughts: - The Agence Universitaire de la Francophonie is a partner of CARI http://www.cari-info.org/index.php?option=com_content&view=article&id=49&Itemid=81 - AIMS is Sage friendly and has a location in Dakar http://www.aims-senegal.sn/ Cheers, Nicolas -- Nicolas M.

Hello, Is the conference in french ? (the title is in english but most information are in french) I am interested but the themes of the conference looks far from Sage capabilities: theme 1: Complex Systems Modelling theme 2: Scientific Computing and Parallelism theme 3: Signal, Image, Speech and Multimedia theme 4: Artificial Intelligence & Computer-based Collaborative Environment theme 5: Software Engineering and Information Systems: Models, Methods and Applications theme 6: Computer networks, Telecom, Embedded Systems, Distributed Systems and Mobility I will start writing a project if others show up and would be happy if anybody has suggestions fitting into the themes.

Salut Vincent, Thanks for taking the lead for investigating this opportunity! I won't be able to participate myself, as I have a lot of teaching in the Fall.

Yup, we are a bit on the side, fitting partially in theme 2 and to a lesser extend theme 1. They have had scilab tutorials previously which is not completely different. The main question is whether there is a large enough audience for a tutorial to make sense; I have no idea at this point. Cheers, Nicolas -- Nicolas M.

I'll be at a different conference during the second half of the week, so it wouldn't make much sense for me.

[sage-devel] math software and China
Strange subject line, right? But read this post from ask.sagemath: +++ thank you very much! better a notebook servers to China,there are at least 600.000.000 people in internet. many kinds of Python books in China bookstore,but no many people deeply study it. in China,many people use mathematica,because mathematica 9.01 and maple 17 is free download every where magma 2.15 free download in China. in China nobody and no college pay magma V2.20,if pay one times,magma V2.20 will be free downloaded all China in China,95/100 windows OS are free downloaded,no pay a cent to Bill_gate +++ Well, I guess the situation with respect to software piracy in China (and presumably elsewhere) is well-known. I especially find the quote about Magma v2.20 interesting. Anyway, what are the implications of this for Sage - even the cloud? I have no prediction, but it seems pretty important. Certainly one issue this same poster has mentioned before is that the Great Firewall causes problems (see William and cjsh's brief conversation at http://ask.sagemath.org/question/3227/ ). So I think that this is worth discussing, especially if an entire huge country is essentially committed to proprietary software because it doesn't function in a proprietary way there; it makes some practical arguments for open source rather less compelling. Are there any researchers thinking of planning a Sage Days in the PRC? That would be really ground-breaking. - kcrisman -- You received this message because you are subscribed to the Google Groups "sage-devel" group.

Re: [sage-devel] math software and China
I do know someone in Beiljing who does want to run a Sage Days -- there was a posting to this list a few months ago. He is Zhibin Liang and did a number theory PhD in Cambridge (UK) not long ago. If China has such huge resource then surely someone there could run a Sage notebook server. Are they somehow asking for someone outside China to provide one which can be used from China? Surely any open Sage server could be used from there? John On 21 January 2014 13:53, kcrisman wrote: > Strange subject line, right?

I agree it is ambiguous. The poster also complained about not being able to use certain North American servers - well, those servers are restricted to on-campus use, as far as I know!

[sage-devel] nOOb wanting help with $make doc
I have an issue with
$make doc
, I don't have much of an idea where the issue may lay.
$make build
works fine.
Got "undefined symbol: FVS" as error with
$make build
before I adding build flags; "-shared -fPIC -Wl,--no-undefined". Have also
tried "-Wl,-soname,libsomewhatfptufvs.so".
The files "sage/local/lib/libsomewhatfptufvs.so" is also about same size as
executable.
Have tried to follow other spks's like cliquer.

Sry if I misunderstand, not familiar with you use the word "prototype".
Forgot to mention that I try to wrap a spkg written in C/C++ into sage. True
that I have not posted the definition of FVS. Among other code, following
code I believe is build during
$ ./sage -f somewhatfptufvs
int FVS(
int ** list,
my_gal *G//IN
)
{
#ifdefdo_iteration_rereordering_on_adjacency_matrix_while_mainly_using_adjacency_list
do_adjacency_matrix _G(*G);//IN
#else
__graph_structure _G(*G);//IN
#endif
return FVS(list,_G);
}

[sage-devel] Re: upcoming Sage Days
Hi, So it seems pretty clear that if I do Bug Days in San Diego in March, it would be pretty lonely. So what is interest like in doing the Bug Days right after the "Sage on the Web" days? I.e., during the end of June? So we would have the following: * Sage Edu Days 6: University of Washington, Seattle (June 18-20, 2014) (subject to funding) * Sage Days 59: Sage on the Web, University of Washington, Seattle (June 16-20, 2014) * Sage Days 58: BUG Days, University of Washington (June 21-??, 2014) What do you think interest would be like? Basically we would have three different funding sources, but adjacent events, and just shift gears (and shuffle participants) somewhat from one to another. The bug days could go to the end of June even, depending on interest. -- William On Tue, Jan 21, 2014 at 5:44 AM, Volker Braun wrote: > I'll be at a different conference during the second half of the week, so it > wouldn't make much sense for me. > > > On Tuesday, January 21, 2014 5:59:26 AM UTC, William Stein wrote: >> >> From my side the best dates for Bug Days would be March 17-21 (a >> Monday - Friday). > > -- > You received this message because you are subscribed to the Google Groups > "bugdays" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to bugdays+unsubscr...@googlegroups.com. > > For more options, visit https://groups.google.com/groups/opt_out. -- William Stein Professor of Mathematics University of Washington http://wstein.org -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
