I thought I had reviewed that ticket, but apparently I have tried it out but not yet reported. As wjp says on the ticket, to try it out you only need to install the new spkg and the second patch. But to adopt this spkg as part of Sage proper would need a vote here. I suggest that wjp helps

I gave a plenary talk at a big MAA meeting a few months ago. It was entirely a live demo using the Sage notebook. It went perfectly. Stan Wagon gave another talk in using the Mathematica notebook, and it surprisingly had numerous bugs/problems as a result of bugs in Mathematica's

[sage-devel] how to submit upgraded biopython spkg for python-2.6?

2009-07-26 Thread tkeller
Thanks for all the recent work upgrading the base python distribution to 2.6, I imagine it was quite a task. I noticed that installing the biopython-1.49b spkg is broken from the upgrade . I have upgraded the spkg to 1.51b and it installs and works fine on my sage-4.1 installation. Is there a

Hi, Thanks for pointing that out. I have made a 1.51b spkg, but decided to wait a week or two for the final 1.51 to come out. But I didn't realize that the 1.49b install was broken. Anyway if you have any interest in helping out, you should get a trac account. Just email William Stein for

This seems interesting. I teach circuits and networks every semester as an application of ODEs/systems of ODEs. The EMF is not necessarily constant and occasionally we might have a variable term (eg, a variable capacitor). Questions: 1. Does his program allow non-constant terms and symbolic

Hello, http://www.circuitengine.com is my site. It uses Gaussian elimination and a fifth order adaptive step-size Runga-Kutta solver to simulate electric circuits that are drawn by the user. I created a login for the sage development team to use. Please feel free to experiment with my program.

Wow, my field! :) I would like to add that SAGE can open a new door to circuit analysis, thanks to its symbolic manipulation. A friend of mine adopted the techniques to solve the circuits defined by a netlist like in SPICE. If you adopt that same technique in SAGE, you are allowed to define one

Ok, I posted my spkg at: http://trac.sagemath.org/sage_trac/ticket/6634 It would be great if you (tkeller) got a trac account, since currently I don't know any other sage developers who have any real interest in this (partial exception of William Stein but clearly he has a lot on his plate).
