[sage-support] Sage Days 10: October 10-15, Nancy, France
Hi all, this is a reminder that Sage Days 10 (SD10) is fast approaching! It is still possible to register until October 3. See http://wiki.sagemath.org/days10, where you can see the scientific program, with the titles and abstracts of the invited and contributed talks. After SD6 in Bristol last year, SD10 will be the 2nd Sage Days in Europe, and a unique opportunity to discuss with the Sage developers. Two extra special events are planned for SD10: * on October 11, there will be a sage-combinat session: The purpose of the *-Combinat project is to provide an extensible toolbox for computer exploration in algebraic combinatorics, and foster code sharing between researchers in this area. We will present the history, features, and design of MuPAD-Combinat, and discuss the timeline, difficulties, but also great technical and community opportunities that arise from the ongoing port as Sage-Combinat. * on October 14, Robert Bradshaw will give a plenary demonstration of Sage. If you have any questions, feel free to email me or any of the other organizers! On behalf of the organizing committee, Paul Zimmermann PS: I take the opportunity to advertize a workshop on integer factoring that will take place just before SD10 in Nancy: cado.gforge.inria.fr/workshop/. --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

[sage-support] Re: question on using integral() in sage. Fourier transform of unit step function.
It doesn't converge because in your first post you said assume(f>0) Its convergence is the same as integral( cos(2 * pi * f * t), t , 0 , Infinity) (think about area under a curve...). By the way, sage gives: sage: t = var("t") sage: x = var("x") sage: assume(x>0) sage: integral( cos(2 * pi * x * t), t , 0 , Infinity) ind What is "ind"?

[sage-support] problems with install path
L.S., When updating to Sage 3.1.2 I run into the following problem: Am using a Mac G4 dual core, OSX 10.4.11. Used a previous version of Sage without apparent problems. Updating to 3.1.2 however was not without hickups: copying Sage with the finder resulted in error messages that duplicate names were not allowed. Removing all visible traces of Sage from /Applications and then installing with Terminal (sudo cp -R -P "/Volumes/sage-3.1.2-osx10.4- ppc-PowerMacintosh-Darwin/" . inside the Applications folder) appeared to work fine. Starting Sage however resulted in the following: /Users/arnold>cd "/Applications/sage" ; "/Applications/sage/sage" -- | SAGE Version 3.1.2, Release Date: 2008-09-19 | | Type notebook() for the GUI, and license() for information.| -- The SAGE install tree may have moved.

The server directory is suddenly out of disk space, so the server can't work. So I've deleted a bunch of files, so now the server works again.

William, Thanks for the reply. And I understand that could happen. Well, it looks like the content of one of my worksheets is gone. In my case, that's really no big deal. But I hope other people who have more substantial worksheets in that server won't encounter the same problem.

I had the content earlier this morning. But couldn't run sage on it. I might accidentally click the "discard and quit" button. But if I'm not mistaken, usually the old content will still be there. I think (and hope) this is an isolated case.

[sage-support] long arithmetic
Using Sage I solved a long list of equations and put the solutions (s) in a list; e.g.: sage: for j in range(52,54,1): q = slst[j] j=q[0]; k=(q[1]); s=(q[2]) (q,j,k,s) : ([52, 30, 2081203288L], 52, 30, 2081203288L) ([53, 53, 17903198518682712L], 53, 53, 17903198518682712L) Now I want to plug j and s into the list of y equations so that I can do further calculations involving i. But Sage appears to be getting hung on the s being long: sage: for j in range(52,54,1): q = slst[j] j=q[0]; k=(q[1]); s=(q[2]) y = 2*(2**k)*i + s (j,k,s,y) : ... ... TypeError: unsupported operand parent(s) for '+': 'Symbolic Ring' and '' When I take the s out of the equation for y it's OK: sage: for j in range(52,54,1): q = slst[j] j=q[0]; k=(q[1]); s=(q[2]) y = 2*(2**k)*i (j,k,s,y) : (52, 30, 2081203288L, 2147483648*i) (53, 53, 17903198518682712L, 18014398509481984*i) FWIW: sage: type(j), type(k), type(s), type(y), type(i) (, , , , ) None of the tricks I tried have convinced Sage and y that s is OK. --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---
[sage-support] Sage editor
I run Sage on my Mac rather than on the web. I often bring up the previous command and edit it then rerun it. The editor is very tedious in that the only way I have figured out how to move the cursor around in the text is one character at a time using the left and right arrow keys and the back-space-delete key. Given a several-line for-loop to edit this can be frustrating. Am I missing something obvious to everyone else? Is this a feature of the Mac rather than Sage? A less-than-satisfactory work-around is to copy/paste to a programmer's editor, do the change, then copy/paste back to Sage. Which leads me to another and related question. Are the editing capabilities of Sage when used with cells (as described in some of the Sage ref's) on a web server significantly better? If so would I be well advised to install web server software on my Mac and use Sage that way? (I don't have 24x7 fast web access...) Is that installation process complicated?

Sage comes with one. You can try it out by just typing sage: notebook() which will start the web server that sage comes with and open up your browser to the right page.

In many OS X applications, ctrl-option-b jumps back by a word (roughly standard readline behaviour) but as far as I can tell, nothing like this works in sage's command line (which is a shame.)

I'd experiment to find the meta key if you'd just ship me a mac :). I'd even try to figure out how to configure the meta key to be whatever you wanted.

For earlier releases, check for settings or Get Info in the menus, and that should lead you to a similar choice for "option as meta". I don't recall when this capability was added, but I think it predates the earliest Mac OS X release we support. Justin -- Justin C.

I'll guess that it's a difference between versions (1.2.22 vs. 1.2.24), but I can't find old source on the libpng site, and it doesn't show up on the Darwin site (which I infer means that they did not change anything).

I am playing with libpng-1.2.32 since that is the latest release and also has a boatload of security updates since the lowly 1.2.22 that we ship. Hopefully this will resolve the symbol missing issues. I am testing 3.1.3.alpha0 on OSX 10.5 to see if I can hit any of those problems. > Justin Cheers, Michael > -- > Justin C.

I still don't see how parallel make impacts numpy, so if you could send me the portion of the blown up numpy build with parallel make I could attempt to figure out what is wrong. > Justin Cheers, Michael > -- > Justin C.

Do you mean you want the matrix as a matrix over the integers rather than over the integers mod 9? If so, then you can do the following: sage: H = G.change_ring(ZZ); H [5 0 0 0 4] [4 5 0 0 0] [0 4 5 0 0] [0 0 4 5 0] [0 0 0 4 5] sage: H.base_ring() Integer Ring --Mike --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

You can relabel all the files so that Sage and SELinux can play well together, but adding new pages to the wiki might prove difficult since those new files need to inherit the right ACLs. > cheers, > Adam Cheers, Michael --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

Thanks. Numpy is complaining about a missing math module, but I think that is more likely caused by the libpng.dylib disaster than anything else. I just checked the python.spkg and we are running "make install" with parallel make, which I would guess is not a good idea :) The ticket for that issue is #4174 and there should be an spkg shortly. > Justin > Cheers, Michael > -- > Justin C.
