[sage-support] Re: How to refer to the reference manual when writing a tutorial?
Maybe #6495 would make this possible? Just a guess. Yes, I just check this. With #6495 in place, I added this to some random file in the developer's guide, rebuilt it, and the link worked: Great! I hope the same holds for thematic tutorials... Huh, I didn't expect that, but that is great news. -- You received this message because you are subscribed to the Google Groups sage-support group.

[sage-support] Re: Sage Crash Report
Am I correct in saying that you opened Sage for the first time, and then typed sage: notebook() and that's when it crashed? It looks like your permissions are not correct, or at any rate that you do not have permission to make a new directory in your .sage/ directory OSError: [Errno 13] Permission denied: '/home/surendran/.sage/temp/angeli_acer/2800' What do you get with ls -al | grep .sage from the command line, and do you have admin rights on the computer you are using?

[sage-support] berlekamp massey / connection polynomial / lfsr
Hello, this is my first post to the list. I am trying to use B/M algo included in Sage. Now, berlekamp_massey([GF(2)(0),0,1,0,1,0,0,1,0,1,1,1,0,0,1,1,0,0,0,0,1,0,1,1,0,1,0,1,0,0,0,1,1,1,1,0]) evals to f(x)=x^5 + x^3 + x^2 + x + 1 which is the minimal poly. Also, I know that when I take the reciprocal (x^5*f(1/x)), I find g(x)=x^5+x^4+x^3+x^2+1 which is the connection poly. of this LFSR. My question is how can I regenerate this sequence using this connection poly.? Providing initial states 0,0,1,0,1 yields to another sequence: (0 0 1 0 1 1 0 1 0 1 0 0 0 1 1 1 0 1 1 1 1 1 0 0 1 0 0 1 1 0 0) I've tried several different approaches but got no luck. -- Thank you, evrim. -- You received this message because you are subscribed to the Google Groups sage-support group.

[sage-support] Possible to have a notebook server without state like wolframalpha.com just for single commands?
Sage notebooks are great but take a lot of RAM (I assume) partially because they need to remember all the history of the current session. Is it possible to trade history for responsiveness/memory by somehow running the notebook server to accept single commands and then forget the results? I'm envisioning something like wolframalpha.com where a teacher can ask all students to type single commands at a time without the need for saving history.

[sage-support] Re: Don't know a PDF representation for alpha in graphics?
I have uploaded a patch to the trac, ticket 13732, which fixes this for all the plot commands that seem to accept alpha. (To find them, I performed a grep alpha sage/plot/*py and looked at those files.) The doctests in sage/plot pass for me, though I had to make some changes to older doctests because float gives a different output; I haven't yet tried doctesting anything outside of that directory. I couldn't find anything that made the save command choke like this except the alpha option, though I didn't try very hard. I hope someone reviews it; it should be easy, unless I did something stupid. john perry -- You received this message because you are subscribed to the Google Groups sage-support group.

[sage-support] Re: Don't know a PDF representation for alpha in graphics?
With this change, I can sage PDF with alpha, and it probably fixes a lot of other thing Huh. See http://trac.sagemath.org/sage_trac/ticket/14074 for an example where alpha works fine with saving as a pdf. Of course, you could always put the alpha to float(.5) or something... s, as well. -- You received this message because you are subscribed to the Google Groups sage-support group.

Re: [sage-support] Re: Clearing the Terminal when running Sage
Thank you everyone for the help! But, in the octave_console provided by Sage, ctrl+L does not work! Isn't this bug (given that it works when I run Octave from outside Sage)?

Oh wow that is soo awesome. Someone read my mind. I've been selling Sage to my students with a slightly inadequate server but Sage Cell Server will dispense with the need for passwords, memory issues and more.
