[sage-support] 3.4.2 merge plans
Hello folks, now that 3.4.1 is more or less done the plan for 3.4.2 is emerging. The main goal here is to get out a release quickly and mop up loads of patches in trac which have been reviewed or are awaiting review. I have moved every open patch from 3.4.2 to 4.0 to keep the 3.4.2 milestone clean and simple, so if you open a ticket against 3.4.2 make sure to post a patch quickly since I will otherwise bounce it to 4.0 :) If you have some time it would also be very nice if you could review a couple tickets so that the backlog in trac of unreviewed patches goes down.

Is there a way for someone to do such an interaction and post it on the web for others to use directly from the web, without having to have sage installed and without having to do what I am doing now? (i.e. copy code etc...) If so, this would be really cool. If not, any plans to have this feature in the future in sage? It would be like running a applet inside the browser in a way.

[sage-support] shift-return, shift-enter, click-mouse-on-evaluate. on evaluating a cell in a notebook
Hello; It is a bit annoying having to hit 2 keys (i.e. reach out and use both hands) each time in order to evaluate a cell in sage notebook. I am using windows, and I have to hit SHIFT-ENTER, or SHIFT-RETURN, or I could use the mouse, point it to the little 'evaluate' link below the cell, which is also annoying. But it would be much easier to have ONE key. In Maple, the RETURN key will cause evaluation, and in Mathematica the ENTER key. Can one tell sage to use the ENTER key only (without the shift) to cause cell to evaluate? and have the RETURN key just starts a new line (i.e. as in Mathematica). May be with some options or some configuration setting somewhere? I think Mathematica got it right here. In Maple, to start a new line and not cause evaluation, one hits SHIFT-RETURN (again, this is using the notebook interface, i.e. via the browser interface).

[sage-support] Re: jsmath fonts bafflement
OK, thanks for the detailed description of what is happening. Now
this makes me think that this IS a jsMath bug, and not an improper
image font installation. If the image fonts are working in Firefox,
then they are installed properly.
The error you are getting about jsMath thinking that you are trying to
load jsMath from a different server is the key, here. It is not able
to load ANY of its extra files (including things like the control
panel, and IS-specific customization files) because jsMath is confused
about where it was loaded from. What I suspect is the problem is that
the port number is confusing jsMath in IE. Every browser except IE
normalizes URL's so that they include the protocol, host, port
number, etc, so when jsMath looks to see where it was loaded from so
that it can load additional files, that information is all right
there. But in IE, the URL is left as it is originally in the HTML
file, so jsMath must reconstruct it itself. It looks like it is
leaving out the port number, and so jsMath is looking for its
components in the wrong place, and so not finding them.
As an experiment, if you could insert the lines
script
jsMath.Autoload = {root: https://99.240.209.8:8000/}
/script
to the font test HTML file just before the script tag where jsMath.js
is loaded, and then see if that makes it work in IE7, that would tell
us if this is really the problem.
In the meanwhile, I will work on that part of the jsMath code and get
it to include the port number.

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. In any case, I'm happy not to spend any more time on it
myself.
If an installation problem is the conclusion, then I'd like to spend
at
least a bit more of my time on it, as it would clearly be a Sage
problem
then. It seems funny to me that it would work in one browser, but not
another.
I think Davide's suggestion above (look at the font mode and jsmath
version number for both IE and Firefox) might help pinpoint the
problem.
Do you see the same problem with sagenb.org? That server has the
image
fonts installed as well.
When I attempt to load a worksheet from my server with IE7, I get a
dialog In order for jsMath to be able to load the additional
components that it may need, the jsMath.js file must be loaded from a
server in the same domain as the page that contains it. Because that
is not the case for this page, the mathematics displayed here may not
appear correctly. When I view worksheets in IE, I see raw latex
where I should see rendered latex.
In IE, nothing happens when I click on the jsMath button at the bottom
right - i.e. I cannot open the jsMath control panel. Also note that
the jsMath button is only seen when I scroll all the way to the end of
the worksheet, unlike with other browsers where it is always visible
at the bottom right of the screen. I assume IE is not properly
rendering this element.
In Firefox, no jsMath font dialogs appear, and the latex code is
rendered. The font mode is shown as Image symbol fonts, and the
jsMath version is 3.6a.
At sabenb.org, I get no jsMath font warnings in IE. Initially, I see
raw latex, but eventually it is replaced with properly rendered
latex. The control panel shows the font mode as Image symbol fonts.
I viewed my server again in IE, and had the same problems that I
reported above.
I conclude that I have a problem with the image font installation on
my server. But I have no idea how to troubleshoot it.
For info, my public worksheets are athttps://99.240.209.8:8000/pub/

I need some help deciphering how to do this. I am very new to sage,
and have not yet dug too deep into the underpinnings. I can't find an
html file for my font test worksheet. Looking at the text file that
appears to define the worksheet, I don't see any script tags. I tried
adding those script lines directly before the first cell, and in the
first cell that appears to call for jsMath fonts, and at the very
start of the file, but neither change made any difference in IE. But,
if I look at the Font test page html source in my browser, I see that
even if I add your script at the very start of the worksheet file, the
script is loaded well _after_ jsMath.js is loaded.
I clearly have not accomplished your request. Maybe I need to test a
temporary modification to jsMath.js, but I do not know javascript, so
I don't know what changes to make. Or maybe I need to temporarily
modify whatever code creates the html headers for worksheets, but I
have not yet found where that code is.

Well, one could click Evaluate, though of course doing it a lot could be annoying/repetitive stress inducing... I have been trying different things on a colleague's normal non-laptop PC keyboard; perhaps 2nd and 3rd or 2nd and 4th fingers (counting thumb as 1st finger) would work for you? I really think that some combination of pointer + another might be suitable, if your keyboard configuration is similar to hers. Of course, this means one has to shift the hand every time, but only right-left, not twisting (I hope). However, I doubt that Return will become even an option, because one would want multiple lines in a single cell. I have no idea what the status of Enter would be, or even if every OS/popular browser would recognize the difference. Minh? But keep asking these kinds of questions. A while ago there was some very helpful feedback on the best way to default-show graphs for different types of color-blindness - the Sage community is interested in keeping the software usable for everyone, not just 90 wpm typing speed demons with ultra-ergonomic keyboards or perfect voice recognition software :) - kcrisman --~--~-~--~~~---~--~~ 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 -~--~~~~--~~--~--~---

No single change will keep all, or even most, users happy. On my Mac laptop, for example, Enter and Return are on the same key. If I want Enter, I must also press the 'fn' key, way on the far left of the keyboard, which makes it a two-handed manoeuvre. But Shift-Return is an easy one-handed manoeuvre for me, on my keyboard. Whatever change is made, it should probably be easily configurable, to cater for people with different needs, different keyboard layouts, etc. The current behaviour should probably remain the default, to avoid great howls of pain from users who have grown accustomed to it. -- Kevin Horton Ottawa, Canada --~--~-~--~~~---~--~~ 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 -~--~~~~--~~--~--~---

[sage-support] Re: jsmath fonts bafflement
OK, from the testing that I've done, it looks like this is, indeed, the problem, and you won't have to do the testing that I suggested. It turns out that this problem was fixed in version 3.6b of jsMath, and you are running 3.6a, so if you download the latest version of jsMath and replace the copy at javascript_local/jsmath on your site, it should take care of the problem. When you unpack the new jsMath, move the fonts folder from the old one to the new one before replacing the old copy, or you will loss the image fonts that you have installed. You can get the new jsMath from http://sourceforge.net/project/showfiles.php?group_id=172663 Hope that clears up your problem.

There might no longer be any Sage 3.1.4 binaries, but you can download the sources into the current Sage VMWare image, unpack them somewhere in $HOME, run make and they should build fine. Given that a serious number of bugs have been fixed since then as well as numerous enhancements added this is generally not recommended. Moreover, doing the above will in no way help at all. The entire problem is that the default memsize on the virtual machine was increased in 3.2.3 to 512 from 300-ish in 3.1.4. Sage worked for you before, not because you used 3.1.4, but because of a single default setting in the virtual machine. Given that your computer only has 512MB RAM, it's no surprise that a virtual machine can't work if it tries to allocate 512MB RAM too. William Edit the file sage_vmx.vmx and change the line that says memsize=512 to memsize=300 or some other smaller number (between say 200 and 324).

[sage-support] Re: Having a SAGE Math web server on a low cost web hosting site
On Tue, Apr 21, 2009 at 10:20 AM, Gerald Smith mathb...@yahoo.com wrote: Dear Gentlemen, I noticed that the MOODLE educational system is now widely available as a free option at a large proportion of the most popular free/low cost web hosting sites. I myself verified that it took only a few minutes to set up a fully functioning MOODLE server at zero cost to me. This feature will work wonders for popularizing MOODLE far and wide. I wonder why something like this cannot be set up for SAGE Math? If SAGE were readily available on these hosting platforms as an option (probably because of the amount of resources needed for SAGE, it would be an option on a low cost rather than the bottom end completely free web hosting choice), I think it would do much to encourage the wide spread adoption of SAGE Math. I am also curious how dificult it would be to use a low cost web hosting site to set up a SAGE server on my own? These sites typically offer Linux/BSD Unix functionality. If I buy the space, will they allow me to upload SAGE and compile and install it into a directory on the file system assigned to me? If so, how would I set it up so that everybody could access the SAGE notebook server on the site? I have given up trying to make SAGE on my personal computer accessible from the Internet. I was told to use a bridged system for VMWare, but the server simply gives up and refuses to function if I put it up under anything except NAT. I would much prefer to set it up on a low cost webhosting site anyway so it could be available at any time to my students, and we could use it to share worksheets with each other. I think as SAGE becomes more popular in education, having everybody use the www.sagemath.org server will lead to chaos. Those teachers who have access to sympathetic IT directors might be able to set it up on a school district system, but it would be really nice if educators could set it up on their own and have a URL to a SAGE web server that was entirely their own. Having it as an optional package at one or more of these low cost web hosting sites would be a wonderful opportunity for educators without access to institutional IT resources. Has anybody tried this? I would very much like some input. Could anybody with the necessary technical knowledge approach these sites and talk to their directors about offering a SAGE Math web server package as an option for their customers? I am thinking about places like Freehostia, 110MB or GoDaddy. What do you guys think? Sincerely, Jerry The minimum reasonable requirements for building sage from source and running a Sage server are: 1. at least 2.5GB disk space (building sage from source ends up taking 1.9GB once the build finishes, and you want to have room for user data). 2. Linux (BSD is currently _not_ supported) 3. at least 1GB RAM (preferably 4GB) 4. standard GCC build environment (gcc, g++, make) 5. at least two unix accounts on the server Regarding 5, if you want to run Sage on a hosting service such that it is not trivial for any users to hack/break, then you also have to be able to create at least one other user account on the system and setup ssh keys. If a hosting service provides the above, then Sage is likely to work fine. -- William --~--~-~--~~~---~--~~ 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 -~--~~~~--~~--~--~---

Options (1) and (4) appear to be broken: (1) When I type notebook at the prompt, a screenful of information is flashed too quick to read. Thesage login: prompt then appears again, together with the same instructions as before. Towards the end of that briefly-displayed screen of information, I see an instruction to open Firefox to some internet address; but because of the very short display time I'm not able to read that address. (2) Typing off at the prompt causes VMplayer to shut down, which is the correct behavior. (3) Typing manage at the prompt gets me to a man...@sage: prompt from which I can become the Ubuntu root user by typing sudo su. This also is correct behavior. (4) When I type sage at the prompt, I again get a briefly-displayed screenful of information followed by a return to the login prompt.

For reasons I have still not understood, fast_float works faster if the

fast_float in the Sage Reference Manual. For example, I would like to
know how something like this is handled:
var('a t')
F = fast_float(a*t^2 + a*t + a, 'a', 't')
How would I plot F or find its root for a fixed a? plot(F(1,t),(t,-1,1))
does not work, nor does find_root(F(1,t), -1, 1).
I do this in http://sagenb.org/home/pub/69/ by using the standard python
functools.partial:
http://docs.python.org/library/functools.html
Something like:
from functools import partial

The following call, however, still leads to the same error: R=PolynomialRing(GF(2),['x%d'%(i+1) for i in range(21)],order='lex') R.inject_variables() I=ideal([x2 + x1*x2*x15 + x1*x14*x15 + x2*x14*x15 + x1*x2 + x1*x14 + x2*x14,x3 + x2,x4 + x1*x16*x17 + x1*x16 + x1*x17 + x16*x17 + x16 + x17,x5 + x4,x6 + x5*x15 + x5,x7 + x6,x8 + (x4 + 1)*(x13)*((x11 + 1)* (x20*x21 + x20 + x21) + x11),x9 + (x19 + 1)*(x8*x9*x18 + x8*x9 + x9*x18 + x9) + x8,x10 + x9*(x20*x21 + x20 + x21),x11 + x9 + x10 + 1,x12 + x5 + 1,x13 + x12,x14 + (x11 + 1)*(x13*x20*x21 + x13*x20 + x13*x21 + x13) + x13,x15 + x14 + x13])+ideal (sage.rings.ideal.FieldIdeal(R)) I.variety() It is clear, that this is not the way one is supposed to solve such problems. I need to do this computation for comparison purposes, though.

[sage-support] Re: shift-return, shift-enter, click-mouse-on-evaluate. on evaluating a cell in a notebook
Hi kcrisman, On Tue, Apr 21, 2009 at 2:09 PM, kcrisman kcris...@gmail.com wrote: Yes. SHIFT-RETURN could be done with one hand because as you said, the RETURN key is in a very close proximity to the SHIFT key (on my keyboard at least). The problem though, to do this with one hand, one must twist the thumb in 90 degree angle as one it hitting on RETURN key with the index finger, (I do not think I could press both keys with just one finger), and my thumb has a bit of arthritis which makes hard to bend it too much. It is also a bit awkward to hit a key with a finger twisted in this fashion. I just tried it. But it is a good suggestion and shows imagination and thinking outside the box. I think another solution would be to get one of those programmable keyboards and program it to send SHIFT-RETURN when hitting some F key which is not used. And use that F key for SAGE only. Meanwhile, I have to continue to reach out and use both hands in order to evaluate a SAGE cell. Hmm. Well, one could click Evaluate, though of course doing it a lot could be annoying/repetitive stress inducing... I have been trying different things on a colleague's normal non-laptop PC keyboard; perhaps 2nd and 3rd or 2nd and 4th fingers (counting thumb as 1st finger) would work for you? I really think that some combination of pointer + another might be suitable, if your keyboard configuration is similar to hers. Of course, this means one has to shift the hand every time, but only right-left, not twisting (I hope). However, I doubt that Return will become even an option, because one would want multiple lines in a single cell. I have no idea what the status of Enter would be, or even if every OS/popular browser would recognize the difference. Minh? Hmm... It's very difficult for me to productively comment on good/best ways to work around issues raised by Nasser. I'm a touch typist, and am mostly comfortable being so on PC, Mac and laptop keyboards. But keep asking these kinds of questions. A while ago there was some very helpful feedback on the best way to default-show graphs for different types of color-blindness - the Sage community is interested in keeping the software usable for everyone, not just 90 wpm typing speed demons with ultra-ergonomic keyboards or perfect voice recognition software :) -- Regards Minh Van Nguyen --~--~-~--~~~---~--~~ 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 -~--~~~~--~~--~--~---
[sage-support] Re: Errors building sage on Linux: jinja and clisp
Sure, here is the full output: http://www.sendspace.com/file/iulbgo Starting the notebook with various other arguments causes problems in other ways, too. For instance, if I start it with notebook (address='', secure=True) I get a modal dialog saying No hostname specified. Here is the output from that: http://www.sendspace.com/file/b2v8v9 And with notebook(address='') I get Malformed URL and this output: http://www.sendspace.com/file/mivfoi In both cases, however, the server still runs.

I can confirm that making 3.4.1.-rc4 worked just fine. Getting rid of clisp for 4 sounds good. You don't even know how happy I will be once it is gone :) However, there is another niggling problem: I get an annoying internal service error when starting the notebook. I have to navigate tohttp://localhost:8000/withoutthe startup token to login.

I think the problem is that when you start the notebook with the option address='' (which I believe is the deault) this kind of problem can pop up.

Hope this is helpful. Yeah, it is. There has been some discussion to not allow the construct notebook(address='') any more since it causes the above problem. AFAIK there is no ticket to do that yet. If there is consensus that this is the right thing to do I am happy to open one.

Greg Grunberg The screenshot reveals that your CPU is not advanced enough to run this binary build of Sage, i.e. it is missing SSE3 instructions. You can force it to run anyway (see the message Sage is printing), but this will result in Sage exiting during runtime due to illegal instruction error messages if you execute certain code, i.e. large linear algebra problems (where large is roughly a determinant for a 90x90 matrix over ZZ for example).

[sage-support] Re: old snapshots take a *lot* of space
2009/4/21 Jason Grout jason-s...@creativetrax.com: I was just troubleshooting why my sage notebook is slowing way down, especially in saving and stopping. Michael Abshoff suggested looking at the snapshots directory. I discovered that I had over 7 gigs in my sage notebook directory, and most of my worksheets (simple text, maybe an image or two) had 50-100 megabyte snapshot directories. My oldest worksheet had over 11,000 snapshots, each about 770 bytes, but each taking 4K of disk space. So: can I just delete all of these snapshots? Yes. Can we make a sage function that cleans out these snapshots if we decide we don't need them? When the notebook is about to create a snapshot, it *should* clean up old snapshots using some simple criterion, e.g., at most one per hour after the first hour, then at most one per day up to a month, but after a month just one per month, etc. -- William --~--~-~--~~~---~--~~ 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 -~--~~~~--~~--~--~---
