[sage-support] Re: No Jmol-applet in firefox and Opera
Once again me. Maybe the error message has nothing to do with jmol. I opened Opera and I could calculate but got "applet not found" and no error message at all. --~--~-~--~~~---~--~~ 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] No Jmol-applet in firefox and Opera
Hi. This is my second install on a x86/64 Ubuntu system. Last time there has been some trouble with the jmol-Applet and a thing called IcedT or so. It turned out that I simply had to run sage in Opera instead of firefox to get the applet. This time things have changed. In Firefox an applet-wimdow opens and shows the jmol-icon for a instant, then stays black showing "jmol" at the bottom right. In opera I get "applet not found". When using the sage online server I get the applets, which means to me that java is running well. It is a compile-from-source install. There is a working jmol on the system, but installed only locally in a folder and not as a debian package so that there isn't any starting command for jmol known yet . This is the error message when firefox is being used: 2009-10-18 00:15:00+0200 [HTTPChannel,8,127.0.0.1] Request error: Connection to the other side was lost in a non-clean fashion. 2009-10-18 00:15:01+0200 [HTTPChannel,10,127.0.0.1] Request error: Connection to the other side was lost in a non-clean fashion. I guess in opera it's the same error.

[sage-support] Re: Limiting the function value range in 3dplots
Sorry, me again.
Maybe I was wrong to say Sage scales "up". Maybe Sage scales "down".
Howto aviod this?
Thanks

[sage-support] Limiting the function value range in 3dplots
Dear supporters,
again thanks for the great support.
One thing I am missing (or simply not understanding) is 3dplotting
without automatically scaled up range of the function value.
(This is just my first example at hand and surely not a good one:
y, x = var ('x,y')
plot3d(lambda x,y : (bessel_Y(y,x,"scipy",53)).real(), (-0.002,0.002),
(-1,1))
#Put some broader x-range in to see what I mean.)
Please excuse this sloppy written description: Jmol and Sage seem to
try to plot the whole graph even at singularities, then "give up" (at
a level I don't know how to fix) but leave the picture with the scaled
up value range.
Use this link to see what I mean would be useful sometimes (and please
do not blame me because my plot above is another thing as seen there -
I am just playing around and I just took the first example at hand):
http://mathworld.wolfram.com/ModifiedBesselFunctionoftheSecondKind.html
There the value range is simply cut at some point. In the german
wikipedia article on the exponential function it is done in a similar
way by Maple and the whole picture is scaled equally in all
dimensions:
http://de.wikipedia.org/w/index.php?title=Datei:Exp_re.png&filetimestamp=20050215210532
(Put the two lines together without intermedate space.)
Is there a way to limit the value range in a 3dplot other than
limiting the input range (I want to see, say, the region around the
singularity)?
Yours, littlemathteacher

[sage-support] Re: 3dplotting complex functions
Dear kcrisman, I think it would be enough to give an example in the tutorial or in the output of "plot3d?". Even more, an example gives kind of a smooth lesson in how really to use the 3dplotting and the ".imag()" or the ".real()" command at the same time. Starting from Jason's examples I did all I wanted to and even more and I am beginning to understand plotting. Examples are better than new commands, because they are way more flexible and they make you play around. Perhaps it would be nice for the user to find an example how to plot graphs like these http://mathworld.wolfram.com/ModifiedBesselFunctionoftheSecondKind.html in the outputs of "bessel_X?". In this case I succeded in generating some pictures, but they don't look like the ones in mathworld. (But I am not asking for support in this respect.) One thing I am missing (or simply not understanding) is 3dplotting without automatically scaled up range of the function value. Jmol and Sage seem to try to plot the whole graph even at singularities, then give up (at a level I don't know how to fix) but leave the picture with the scaled up value range. Use the link above to see what I mean would be useful sometimes. There the value range is simply cut at some point. In the german wikipedia article on the exponential funcion it is done in a similar way by Maple and the whole picture is scaled equal in all dimensions. But I am going to make a new support question out of that. Thanks a lot. Yours, littlemathteacher On 31 Mai, 04:01, kcrisman wrote: > Ironically, I did something just like this at a talk this week.

[sage-support] 3dplotting complex functions
Dear Supporters, first of all thanks to you all for doing such a great support job to me so far. Now I want to make complex analysis visible and to plot 3d-graphics either of real or imaginary parts of functions. The first step would be to plot the exponential function just like in the german or the us wikipedia article, later to show the branch cuts like in http://mathworld.wolfram.com/BranchCut.html or the gamma function like in http://mathworld.wolfram.com/GammaFunction.html . The reason why my attemps fail might lie somwhere in the defining of variables and in the picking out of the real or the imaginary part. I guess all I need is one working example of how to 3dplot let's say complexplane X real part of the function value. Starting from that example I could do the rest myself, but I didn't find one yet. Could you please post a link to an example? Thanks a lot.

[sage-support] Re: Slackware/Zenwalk package
Dear Michael, dear Minh, I had strongly underestimated the HD-space consumption of a sage server. (I didn't look into the reader ...) Man, it is huge! After re-partitioning my drive I ran the installer in a command line session, like Minh has tought me. It took somewhat between 15 and 18 hours. Now sage is running on that old notebook. You who developed it did a great job. (I am very impressed by that software. I am going to hold some tutorials for the kids at my german high school how to use sage and so to have fun with math. My plan is to tell them that there are only two basic commands you need to know at the beginning, that is the TAB (to complete the command you guessed might work) and after that the question mark and shift-enter to look up the usage. Yesterday I found a third and a very exciting one: "search-doc". I think this one is going to shift sage far beyond the limits of maplesoft and wolfram.) Thanks a lot.

[sage-support] Re: Slackware/Zenwalk package
Dear Minh, dear Michael, thanks a lot. Thanks to Minh for this simple but fine idea to compile in a command line session! Meanwhile the RAM I had bought has arrived and with the now available more than 300 MB I let the compiler run once again. This time it seemed to "freeze" at the same point but I still heard the harddisc working. So I went to bed and this morning the compilation is in fact done, but with an error. The simple but true reason is that there is no space left on the sda1 device, just as the installer told me. So there are still some options left to get a local sage with Minh's manual, more RAM and more HD- space. I am going to report it to you here when the installation is successfull. Also I will look up Minh's wiki in which folder to place sage. Thanks!

[sage-support] Re: Slackware/Zenwalk package
Dear Michael, thanks. When I returned home this evening the process and the whole system seemed to be frozen as if by memory overload. I slowly tried to close some applications and among them accidentally was the bash in which I had opened the file manager (by su root) to cd into the sage folder in order to run the "make" - and by chain reaction the file manager and then the bash with the sage compilation closed. So I can't even say that the compilation literally crashed or froze, only that I am a little too stupid to let it do it's job. Maybe it was wrong to put it into the lib folder. I am still new to linux and this time a wanted sage not to live in any home directory. Which linux folder would you recommend to extract sage into? Maybe it was also wrong to run it from within a root bash while logged in as user (but in ubuntu I did it just this way). I made a compressed archive file out of the install.log and now I am thinking about where to save is so that it can be linked to. In the meantime maybe the last lines might be significant to you: [Code] make[5]: Entering directory `/lib/sage/sage-3.4/spkg/build/ linbox-1.1.6/src/interfaces/sage' /bin/sh ../../libtool --tag=CXX --mode=compile g++ -DHAVE_CONFIG_H - I. -I../.. -I../.. -I. -I../../linbox -g -I"/lib/sage/sage-3.4/local/ include/linbox" -I"/lib/sage/sage-3.4/local"/include -O2 - DDISABLE_COMMENTATOR -I/lib/sage/sage-3.4/local/include -I/lib/sage/ sage-3.4/local/include -I/lib/sage/sage-3.4/local/include -g -fPIC - I"/lib/sage/sage-3.4/local/include" -I"/lib/sage/sage-3.4/local/ include/linbox" -L"/lib/sage/sage-3.4/local/lib" -I/lib/sage/sage-3.4/ spkg/build/linbox-1.1.6/src -I/lib/sage/sage-3.4/spkg/build/ linbox-1.1.6/src/linbox -I/lib/sage/sage-3.4/local/include -I/lib/ sage/sage-3.4/local/include -D__LINBOX_HAVE_CBLAS -c -o linbox-sage.lo linbox-sage.C mkdir .libs g++ -DHAVE_CONFIG_H -I. -I../.. -I../.. -I. -I../../linbox -g -I/lib/ sage/sage-3.4/local/include/linbox -I/lib/sage/sage-3.4/local/include - O2 -DDISABLE_COMMENTATOR -I/lib/sage/sage-3.4/local/include -I/lib/ sage/sage-3.4/local/include -I/lib/sage/sage-3.4/local/include -g - fPIC -I/lib/sage/sage-3.4/local/include -I/lib/sage/sage-3.4/local/ include/linbox -L/lib/sage/sage-3.4/local/lib -I/lib/sage/sage-3.4/ spkg/build/linbox-1.1.6/src -I/lib/sage/sage-3.4/spkg/build/ linbox-1.1.6/src/linbox -I/lib/sage/sage-3.4/local/include -I/lib/sage/ sage-3.4/local/include -D__LINBOX_HAVE_CBLAS -c linbox-sage.C -fPIC - DPIC -o .libs/linbox-sage.o [End Code] But please don't put too much effort into helping me make sage run on this old notebook, Michael.

[sage-support] Slackware/Zenwalk package
Greetings from Franconia. I tried to use the compiler to build Sage in my Zenwalk system (Zenwalk is based on Slackware Linux), but this time it did't work (might be due to the antique hardware I am using this time). I would like to put a request for a Zenwalk-package of Sage to the Zenwalk commulity, because I consider myself not experienced enough to build one. Would it be o.k. to do that, I mean concerning legal matters?

Well done. I've built it from source. (To be honest, all you do is watch the mighty programm building itself) It took a while, but Sage it running very fast now. But when it comes to plotting, Sage says Firefox hasn't enabled Java, what is simply wrong. What shall I do?

[sage-support] Re: ILLEGAL INSTRUCTION sse4_pni
Thanks a lot. 3.2.3 is running fine without any error message. And it is very impressive to me and my collegues. We're considering to load it on our school server. The best thing for education and pupils is that it is running in your browser and so you only have to copy and paste a little and to know how to handle only two basic commands, as there are the question mark and the TAB key. The rest is done for you by Sage. So if you want to study and explore math you don't have to master a certain command code any more. It' great and it's fun. And one thing further: since more and more lectures in math and computer science are stepping from commercial programs to sage our pupils might be able to switch very easily from school math to college math and to focus on the subject and not on obstructive and strange working tools. For I believe that coding is a great way to understand math on a basic and even on a philosophically adequate level, but math is not essentially the same thing as coding and that in the end it should be possible to study math without studying computer science. Well, that's just an opinion ... Thanks for the support by Dr. Stein himself. And greetings from Germany to Dr. Stein and his team.

[sage-support] Re: ILLEGAL INSTRUCTION sse4_pni
OK. Let me try to be precise. The information I gave in my post was not correct. I have installed sage-3.2.2-ubuntu32bit-intel-i686-Linux and I receive the error message "... ILLEGAL INSTRUCTION ... pni" but however this version seems to be running well. In order to try the next version I have taken the wrong file (the one for xeon), as you have shown me. Great help. Thanks. I will try out the one for PentiumM. But what about the error message in my recent version (3.2.2)? Can this problem do any harm to me? Until now I haven't found any bugs or restrictions in my running version in spite of the error message ... well, still I am using it only for a short time.

[sage-support] ILLEGAL INSTRUCTION sse4_pni
I am running Sage 3.2.3 on an old Pentium 4 M with Ubuntu Linux for some hours now and I am getting the well known ILLEGAL INSTRUCTION message: ... The following processor flags were on the build machine but are not on this computer: sse4_1 pni I am running Sage Notebook in my browser and as far I can see in these few hours it works quite well. Do I have to change anything anyhow? What is the problem? Thanks a lot.
