[sage-support] notebook password
I use Sage via the notebook() feature. As advertised it opens the notebooks in my default browser. But I want to use a non-default browser so sent it to the link http://localhost:8000/ per instructions. It won't let me open any one of my notebooks without a password. But I did not ever set a password and without an old password it does not want to let me set a new one. Can I tell Sage which browser it should use? How can I assign a password? I use Sage on a Mac and am the only person using the Mac.

[sage-support] long arithmetic
You support people are doing a great job. I need to pick up the thread from last week but am not sure the proper protocol for doing that. http://groups.google.com/group/sage-support/browse_thread/thread/c93cc7d04d998ea1?hl=en My follow up question pertains to the patch you'all hurried up to create. I know you didn't apply it on my Mac so how do I take advantage of it? Do I download the latest version of Sage and install it? The version I am using is 3.0.2. Thanks again.

[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 'type 'long'' 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) (type 'int', type 'int', type 'long', class 'sage.calculus.calculus.SymbolicArithmetic', class 'sage.calculus.calculus.SymbolicVariable') 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? Bob Wonderly PS So far you support people have done just fine answering this old programmer but Sage newbie's questions.

[sage-support] var names
After being a few hours into a Sage session I start losing track of all the vars I have defined. Is there a way to get Sage to list them for me?

[sage-support] using ==
Still a Sage newbie. I discovered the == comparison operator and tried this: sage: 2*n+3==(6*n+9)/3 True sage: 4==5 False So I thought Sage would be useful to check on some messy algebra I was doing (one example out of many): sage: (2*j*2^(18*q) + 13*2^(18*q)/27 - 13/27) == (2^(18*q)*(2*j+0)+13*(2^(18*q)-1)/27) 2*j*2^(18*q) + 13*2^(18*q)/27 - 13/27 == 2*j*2^(18*q) + 13*(2^(18*q) - 1)/27 (well the email program folded the lines so for clarity I refolded them in a more-readable manner) But that comparison did not tell me what I was expecting. In fact it didn't tell me anythig. The following is a rather lame substitute (proof by examplebig laugh): sage: for q in range(2): for j in range(2): (2*j*2^(18*q) + 13*2^(18*q)/27 - 13/27)==(2^(18*q)*(2*j+0)+13*(2^(18*q)-1)/27) + 1 : False False False False sage: for q in range(2): for j in range(2): (2*j*2^(18*q) + 13*2^(18*q)/27 - 13/27)==(2^(18*q)*(2*j+0)+13*(2^(18*q)-1)/27) : True True True True (No refolding of lines there...) At least that approach serves as a credibility check. The question is: how do I use Sage to check on my algebra?
