Re: [sage-support] Re: Problems running the app under Mac OS X 10.6.8
Questor, It looks like you have a permissions issue (perhaps among other things). Did you install it as a different user than you are running it as? If so you might be able to fix it by changing the owner to your user in info. i.e. Select the app in the Finder, File Get Info, then in the bottom section of the info window there should be a gear with which you can Make USER (me) the owner. Anyway, this bug is now tracked at http://trac.sagemath.org/sage_trac/ticket/11755 In the end, it works for me (both terminal and notebook sessions) running it as the same user that I installed it. My other thought would be that you got a corrupted download. If you still have the disk image you can run md5 ~/Downloads/sage-4.7.1-OSX-64bit-10.6-x86_64-Darwin-app.dmg in a terminal (changing the path as needed). You should get 129a710a286da6d99e46fa2607512d95 as noted on http://boxen.math.washington.edu/sage/osx/intel/index.html. Hopefully those will solve your problem, but if not let us know. -Ivan On Aug 28, 2011, at 8:05 PM, Questor wrote: menu Terminal Session Sage gives /Applications/Sage-4.7.1-OSX-64bit-10.6.app/Contents/Resources/sage/ sage; exit % /Applications/Sage-4.7.1-OSX-64bit-10.6.app/Contents/Resources/sage/ sage; exit -- | Sage Version 4.7.1, Release Date: 2011-08-11 | | Type notebook() for the GUI, and license() for information.| -- Traceback (most recent call last): File /Applications/Sage-4.7.1-OSX-64bit-10.6.app/Contents/Resources/ sage/local/bin/sage-location, line 226, in module if install_moved(): File /Applications/Sage-4.7.1-OSX-64bit-10.6.app/Contents/Resources/ sage/local/bin/sage-location, line 77, in install_moved write_location_file() File /Applications/Sage-4.7.1-OSX-64bit-10.6.app/Contents/Resources/ sage/local/bin/sage-location, line 32, in write_location_file O = open(location_file,'w') IOError: [Errno 13] Permission denied: '/Applications/Sage-4.7.1- OSX-64bit-10.6.app/Contents/Resources/sage/local/lib/sage-current- location.txt' logout -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
Re: [sage-support] Re: Bug in Graph.is_chordal
Hello Jan !!! I am sorry for my vry slow answers, I am on vacation right now, with very very bad WiFi connections when I get some. If you think you would sleep better with copying the implementation given in the paper, then the best is probably to write a patch for this. I like mine better, just because I feel like I understand how it works, but to be honest I do not really mind in this case as it is so easy to check whether the code is correct. What would you think of writing a patch to change the current behaviour to match the paper using your code, while letting my version of it (the updated/fixed one) in the code as a comment ? Before returning the result, it should be checked, for instance like I did in my patch. If at some point the value returned is incorrect, the exception should be There was an error in the computed answer... Please report the bug or something alike so that we quickly learn of it and fix the mistake. What do you think ? What I fear the most are silent mistakes.. The ones you do not notice. In these situations I don't mind Sage answering me that it wasn't able to do the computations, especially when the patch is already written :-) If you have time to create the patch, I will try to review it as soon as I get back to the civilisation (possibly next friday). Otherwise we'll talk about it then :-) Thank you for your work, by the way !

I followed a course once on elliptic curves. Here there was no automated checking involved but it instead you had to share your worksheet with the people who grade homework. That also worked quite nice. The sad thing is that the sage server of our mathematics department (https://sage.math.leidenuniv.nl/) is down so I cannot show you how the file looked like. But what it basically did was to use the regular text in the worksheet to ask the questions, and after a piece of text you had an input field where you had to answer it.

[sage-support] Re: Possible to do quizzes and/or practice problems in notebook?
Hi Everyone,
Chris, perhaps another approach is possible. For most mathematical
problems, there are constructions possible that verify the answer.
For example: when solving a system of equations, it is easy to
implement a function that calculates each equation given the answers
provided by the students and checks the answers.
{Default example from solve? below}
x, y = var('x, y')
solve([x^2+y^2 == 1, y^2 == x^3 + x + 1], x, y)
== verify that the answers are exactly what the students answer..
This simple example is perhaps not very good, solve might give the
students a hint how to solve the problem automatically, but you get
the yest of it..

I'm imagining something where the worksheet asks a question and students can type in their answers to see if they are right or not. Links to example worksheets would be very much appreciated if such a beast exists. Another option is to embed Webwork problems into a Sage notebook. Michael Gage and Jason Aubrey (Webwork developers) worked on this during Sage EduDays 3 in June. The nice thing about this is that Webwork could keep track of the answers, you could use the nice features of webwork for checking answers, etc. Email me if you're interested and I can put you in touch with Michael Gage and Jason Aubrey.

[sage-support] Bug in global_height
There is a problem with the global_height function for elements of number fields. The fix would be very simple, just need to add two parentheses to the code. Below is an example of the problem. I'm running Sage version 4.7 on Mac OS X version 10.6.8. sage: K.s = QuadraticField(2) sage: s.global_height() 0.346573590279973 sage: (1/s).global_height() 0.693147180559945 This is incorrect since s and 1/s should have the same height. The problem is explained in the comments made by the author of the code: The absolute logarithmic height of this number field element; that is, the sum of the local heights at all finite and infinite places, with the contributions from the infinite places scaled by the degree to make the result independent of the parent field. However, it is both the arch. and non-arch. contributions that need to be scaled by the degree. The current code of global_height is : self.global_height_non_arch(prec)+self.global_height_arch(prec)/ self.number_field().absolute_degree() The problem would be fixed if this were replaced by: (self.global_height_non_arch(prec)+self.global_height_arch(prec))/ self.number_field().absolute_degree() -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
[sage-support] Re: Bug in global_height
Dear dkrumm, Thanks for your very detailed bug report. I saw you also created a tract ticket for this at http://trac.sagemath.org/sage_trac/ticket/11758 Would you also be interested in writing a patch? The other possibility is to ask if someone here is nice enough to change the sage sourcecode and upload a patch, but then you have to wait till the next sage release till you can advantage of the correct code. And since you already exactly located the bug, you already did the hardest part of the debugging. If you are interested in trying to find out how the sage developement process works please let me know, so I can help you get started.
