[sage-devel] Re: bug in plot3d?
I looked into this, and I found that the mesh=True property is supposed to be passed via RenderParams to jmol_repr(). However, this isn't happening. Graphics3d.export_jmol (which is invoked by show()) has a keyword parameter for mesh, but it is never referenced in the body of the function. I think that setting simply render_params.mesh = mesh after render_params is initialized should do the trick. Does anybody know where/how this functionality was broken? (Also it looks like dots may be broken as well?) I will open a ticket tomorrow and submit a patch. -- Bill On Sat, May 30, 2009 at 5:10 PM, Alex Ghitza wrote: > I have tried this in 3.4.1, 3.4.2, and 4.0.rc2, without success: > > plot3d(lambda x,y: exp(x+y*I).real(), (-2, 2.4), (-3, 3), mesh=True) > > I get a nice looking surface (see attached jpeg file), but no mesh > lines.

[sage-devel] Tutorial topics for SciPy'09 Conference
Hi all, The time for the Scipy'09 conference is rapidly approaching, and we would like to both announce the plan for tutorials and solicit feedback from everyone on topics of interest. Broadly speaking, the plan is something along the lines of what we had last year: one continuous 2-day tutorial aimed at introductory users, starting from the very basics, and in parallel a set of 'advanced' tutorials, consisting of a series of 2-hour sessions on specific topics. We will request that the presenters for the advanced tutorials keep the 'tutorial' word very much in mind, so that the sessions really contain hands-on learning work and not simply a 2-hour long slide presentation. We will thus require that all the tutorials will be based on tools that the attendees can install at least 2 weeks in advance on all platforms (no "I released it last night" software). With that in mind, we'd like feedback from all of you on possible topics for the advanced tutorials. We have space for 8 slots total, and here are in no particular order some possible topics. At this point there are no guarantees yet that we can get presentations for these, but we'd like to establish a first list of preferred topics to try and secure the presentations as soon as possible. This is simply a list of candiate topics that various people have informally suggested so far: - Mayavi/TVTK - Advanced topics in matplotlib - Statistics with Scipy - The TimeSeries scikit - Designing scientific interfaces with Traits - Advanced numpy - Sparse Linear Algebra with Scipy - Structured and record arrays in numpy - Cython - Sage - general tutorial - Sage - specific topics, suggestions welcome - Using GPUs with PyCUDA - Testing strategies for scientific codes - Parallel processing and mpi4py - Graph theory with Networkx - Design patterns for efficient iterator-based scientific codes. - Symbolic computing with sympy We'd like to hear from any ideas on other possible topics of interest, and we'll then run a doodle poll to gather quantitative feedback with the final list of candidates.

I hope the above isn't considered too off-topic here: I'm asking for possible Sage tutorials and obviously this group would be the most likely to provide presenters :) Feel free to provide feedback to me off-list to keep the list traffic on topic to sage-dev.

[sage-devel] include a simplejson spkg?
The patches at #5564 need a json encoder, and there's a ticket to include simplejson at #1510. I'd like to get this spkg in, but there are some comments on that ticket about pickling. I don't know enough of the details, so I thought I would ask if: * we need to patch the simplejson source to support serialization of Sage objects, or if * we can use simplejson without alteration. As it stands, this spkg is holding up some the patches at #5564 which improve UTF-8 handling in the notebook, so it would be very helpful to have it included as a standard spkg. Note that Python 2.6 includes a JSON module by default, so we might have to deal with these issues sooner or later anyway.
