Yes. For the kind of math that I do, in daily research (electronic structure calculations and other quantum mechanics stuff), sympy always worked great, and having no other depenencies than Python, it was exactly what I always needed. For the kind of math that William does, Sage has always worked much better. Also, sympy is just a symbolic library (and that's it, so one has to use other libraries for plotting, numerics, notebook...), while Sage is everything. And thus the motivation for Qsnake --- to have a program, that contains everything and "just works". I would put Qsnake on the same level as psage: http://purple.sagemath.org/, if I understand the motivation of psage correctly, it's aim is also to eventually integrate the useful packages (once they mature from "research" to "production") into Sage. Looking here: http://purple.sagemath.org/goals.html That's pretty much the same motivation for Qsnake. Except that I need a different set of packages (and I need Fortran). Ideally, there would be a huge repository of SPKG packages (just like the huge repository that Ubuntu has, with almost everything), and one could quickly install just what one needs. So I am trying to figure this out too with Qsnake. But it's easier said than done.

I think the main issue is that Sage contains a lot of dependencies and code that are not needed for people doing Finite Element Method (say) work. But nonetheless, there are useful ideas in how Sage is constructed, which Ondrej's project also benefits from. As a related example, shortly after I started Sage (in 2005), Ondrej started Sympy (in 2006), which does symbolic calculus. At least for a while, much of what Sympy did, one could do more quickly in Sage. That said, I just went to the app store recently and downloaded a program called PythonMath, which I find handy on occasion: it turns out PythonMath is basically Python + Sympy, which is _vastly_ easier to port to the iPhone than Sage. > > On Jul 22, 2:35 pm, Ondřej Čertík wrote: >> Hi Thierry, >> >> On Thu, Jul 21, 2011 at 10:21 PM, Thierry Dumont >> >> wrote: >> > Hello, >> >> > I juts read that Femhub (http://code.google.com/p/femhub/and many other >> > urls) uses parts of Sage.

I really love emacs -- it's a work of brilliance. In my case I would say that I use firefox webapps 50% and terminal in the other 50% (e.g. bash, vim, make, etc.). I almost never use any other application. So I think it's clear where this is all going -- moving the terminal like experience into the browser. Which ultimately is way more powerful in some sense (images, equations, fonts, look & feel, links to documentation/web), yet very incapable in some other sense so far: the notebook cell editor has to be improved and maybe some other things: I often like to execute simple python scripts, that for example compile webpages using jinja (or sphinx) or do some sympy calculation, etc. And keep them around. So this workflow maybe translates into being able to easily run worksheets I guess. I don't know if we should even try to translate the whole python development to the web, e.g. being able to create a module

It's easier now; a while ago, the "show" command was enhanced so the
following works like you expect (i.e., "after pic" appears after the
picture). This was initially done to get pictures in html.table to work
correctly.
print "before pic"
show(plot(x^2,(x,0,1)))
print "after pic"

You can use graphics_array, or html.table:
html.table([[plot(sin(a*x), (x, 0, pi),figsize=1) for a in [1..3]]])
graphics_array([[plot(sin(a*x), (x, 0, pi),figsize=1) for a in [1..3]]])

Yep:
p=plot(x^2,(x,0,1))
p.save('test.svg')

Having libraries is a very long-standing request for the notebook.
Here are two ways:
* A graphical "dependency" editor, which lets you select worksheets
from your notebook that the current worksheet depends on. I'm imagining
a tab on the top which pulls up a list of all available worksheets with
checkboxes next to them. You select which one you want, and hit a
button to say that your current worksheet depends on the selected
worksheets. These worksheets are then automatically evaluated before
evaluating the first cell of the current worksheet (so that it works
when you restart the worksheet, etc.)
* More of a python import thing. In this scenario, each worksheet has
an optional filename. If you use python to "import
some_other_worksheet", the path is set up such that the normal python
import mechanism works. This gives you all of the normal python
namespace mechanisms. To enable this, it makes sense to have an
some_other_worksheet.py file automatically created by concatenating the
input cells together whenever the some_other_worksheet is saved. All of
these files can be placed in a special directory that is added to the
import path for the notebook user.

[sage-devel] Re: [femhub] some suggestions to web notebook
I don't notice any difference of speed (I'm on Firefox 3.5.2, btw.) It seems that the editor works as an iframe in the document (that's how FCKEditor (now CKEditor) works, too). The DOM traversal to add elements can be slow, I guess. I haven't read the source code (I'll take a peek at it later) though. BeSpin bypasses the issue of DOM traversal by implementing *everything* in an HTML element: http://ajaxian.com/archives/canvas-for-a-text-editor. It's basically drawing directly on the screen, so it's *very* fast, save for some bugs/issues.

Regarding syntax highlighting, I just found a list on wikipedia of editors we can use: http://en.wikipedia.org/wiki/Comparison_of_Javascript-based_source_code_editors CodeMirror (http://marijn.haverbeke.nl/codemirror/) seems to be the most promising. Here's the demo: http://marijn.haverbeke.nl/codemirror/contrib/python/index.html. EditArea is also good, and comes with i18n: http://www.cdolivet.com/index.php?page=editArea&sess=6ef80ec2026659ce741a8ec0f9b36605.
