[sage-support] How do I make a modified code effective?
Hi, After I modify some codes in a Sage library file, I can rebuild by the command !sage -b right in the running Sage. Then could I make the modified code be effective without exiting the running Sage? Or do I have to exit and rerun Sage?

Hi, try this
r=var('r')
rho = 0.0058/((r/2.4)*(1+(r/2.4))^2)
integral(rho,r,0.01,10).n()

I just installed sage today and probably the problem I have at the

I am very in favor for sage, especially because it is written in
python but I think I need a somehow better (more details) tutorial.
Can anybody link me to another one (I read the tutorial provided on
the sage webpage)?
I define a equation which I would like to integrate... I simplified
the equation to reduce the possible errors
if I use
rho = 0.0058/((r/2.4)*(1+(r/2.4))^2)
integral(rho,r,0,10)
this does not work because for r=0 rho is not defined. But anyway I
want to integrate over the complete radius. What do I have to do?
I can avoid the problem by using
integral(rho,r,0.01,10)
this gives:
0.01392*(10.6953303525 - (125003*log(500012) - 125003*log(10) - 3)/
125003)
how is it possible to force sage to give me one value and not this
helpless term above?
thanks

[sage-support] Sage on Grid. EGEE. gLite.org
Hello sagers, Bearing in mind an idea to put Sage into Grid I want to ask everyone: Does anyone have a need in lots of computing power using Sage ? Does anyone know about EGEE and gLite software for Grid ? Has it been ever discussed to implement Grid functionality into Sage ? (except dsage which is quite different from Grid in EGEE sense) For more info on gLite see glite.org Regards, Serge --~--~-~--~~~---~--~~ 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 URLs: http://www.sagemath.org -~--~~~~--~~--~--~--- begin:vcard fn:Serge A.

By works correctly, I mean that Firefox displays the nicely rendered equations, while IE only displays raw latex code. OK, thanks for the clarification. I had misunderstood. In Firefox, can you click on the jsMath button in the lower right and tell me what font mode is reported next to the jsMath version number? For some reason, the fall back to image fonts is not working for me, using my sage server on OS X, and viewing the worksheet on a PC running IE7. I don't know if there is a problem with the image font installation in sage, a jsMath problem, or an IE problem. But, as long as Firefox will work, I am happy, and feel no need to spend more time on this issue. But, if you think there could be a jsMath bug that you want to investigate, I would be happy to help out. I suspect it is probably an installation problem with the image fonts.

was not helpful concerning this points.
I was in the same situation 3 weeks ago. I have the same feeling with
the manual, and as soon as I get a little bit more familiar with Sage
and the programming/documentation I will try to make some contributions
to the manual. I would recommend you 2 things.
1.- Take a look to Sage For Newbies. Google it, its for free and it
takes approximately 20 min to read the guide and become familiar with
the easy things of Sage.
2.- Log in into the Sage database (sagenb.org) and have a look to the
literally thousands of worksheets there. Many people (included myself)
leave its guides and ways to solve certain task with Sage.
if I use
rho = 0.0058/((r/2.4)*(1+(r/2.4))^2)
integral(rho,r,0,10)
this does not work because for r=0 rho is not defined. But anyway I
want to integrate over the complete radius. What do I have to do?
I can avoid the problem by using
Use the following to define r as symbolic variable
r=var('r')
rho = 0.0058/((r/2.4)*(1+(r/2.4))^2
and solve the integral numerically with the n() method (see The Sage
Tutorial page 6)
sage: integral(rho,r,1E-5,1E5).n()
0.158526563291981
integral(rho,r,0.01,10)
this gives:
0.01392*(10.6953303525 - (125003*log(500012) - 125003*log(10) - 3)/
125003)

[sage-support] Re: Sage on Grid. EGEE. gLite.org
Thank you, Jorge But dSage is more of a distributed system for a cluster but not for the whole Grid (a collection of resources). There is no support for virtual organizations and resource allocation information system. I suppose people involved in LHC should know much better what I'm saying about. But here is few links: http://www.gridcafe.org/ http://www.eu-egee.org/ http://glite.web.cern.ch/glite/ For those that have dealt with VOs and gLite middleware for grid computing: I'm talking about putting Sage on top of User Interface (glite-UI) using benefits of Sage to execute shell commands in code. Thus one would have a full access to Grid power. But it also could be useful to implement Grid interface into Sage. The tools for that do exist: see http://www.geclipse.org/ Basically I have already installed Sage on the SKIF supercomputer nodes and working towards installation on UI from which our users have access to BalticGrid resources ( http://balticgrid.org/ ) Here you can see that Grid users can do computation in Sage on the cluster: http://infosite.balticgrid.org/infosite/?mod=swinfosw=SAGE-3.4 My apologies for such an unstructured explanation. *I'm simply looking here for people who know what the gLite is and also for an answer how this functionality could be useful to mathematician having access with Sage through gLite to lots of worker nodes.* Regards, Serge calcp...@aol.com пишет: In a message dated 4/20/2009 7:22:23 A.M.

[sage-support] Re: Errors building sage on Linux: jinja and clisp
Here is clisp's build.log and error.log: http://www.sendspace.com/file/fct6vu http://www.sendspace.com/file/gnroy3 The only error is: sspvw_sigsegv.d:94: error: too few arguments to function ‘sigsegv_leave_handler’ I have libsigsegv 2.6-1 installed. A bit of googling shows that sigsgv_leave_handler has changed in 2.6 http://www.mail-archive.com/info-...@gnu.org/msg00565.html However, it has been out for months, so I am surprised no one else seems to have had this problem.

[sage-support] faster alternative to using maxima's part function
Hi, Is anyone aware of an alternative to maxima's part function. http://maxima.sourceforge.net/docs/manual/en/maxima_6.html#IDX182 It allows one to access any part of an algebraic expression using various indexes. A list of indexes uniquely defines any part of an expression such as a sum part or exponent. I ask because a while back I implemented a useful function but felt it was too slow because it had to constantly send requests to maxima's lisp interpreter.

Well, clisp is quite buggy to say the least. We tell clisp at configure time to not use libsigsev, but apparently it is still picked up. Sage 3.4.1 out in hours updates clisp to the 2.47 release which AFAIK fixes that specific problem, i.e. it does not bomb out with that version of libsigsev present, but still uses it. If this is a new problem, I can try to submit a patch in a few days. (too busy right now) Don't worry about it, we are dumping clisp in Sage 4.0 and will be using ecl instead.

I ask because a while back I implemented a useful function but felt it was too slow because it had to constantly send requests to maxima's lisp interpreter. The pynac switch is coming in Sage 4.0 and you should be able to do things like that in Sage natively. There are certainly plans to play with the expressin tree, but Mike Hansen can probably tell you how far along that part of the code is.

Well, technically we tell clisp to ignore the absence of libsigsev, so I guess the behavior you see is correct that libsigsev is used. Obviously the configure test doesn't work too well since it fails due to header issues. Oh well, bye bye clisp :) SNIP Cheers, Michael --~--~-~--~~~---~--~~ 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 URLs: http://www.sagemath.org -~--~~~~--~~--~--~---
