 * Wrap NTL finite extension fields (order $\geq 2^{16}$) and polynomials over finite fields.

==== Lower priority issues ====
 * (done) Make generic dense polynomial class in pyrex using C arrays to store coefficients?

== Notebook/web team ==
 . Tom Boothby, Alex Clemesha, [:dmr:Dorian Raymer], William Stein
 * Change the Notebook over to use Twisted
 * Add SSL support for the Notebook (with Twisted/pyOpenSSL)
 * Make public Notebook more secure
  * no cross-side scripting by passing cell output thru MoinMoin
  * send passwords (at minimum) over SSL
  * Sage spawns sage0 in a changeroot jail which is firewalled to only listen on the port assigned to it. This sage0 serves the notebook, which spawns an additional sage0 for each worksheet -- these, in turn, are in smaller changeroot jails which have no internet access, and can only read/write from within their worksheet directory.
 * Add notebook help browser
 * Wikify some parts of the Notebook
 * Add ability to edit plain text Notebook cells and then re-upload
 * Live bootable notebook (Alfredo Portes)
Line 36: Line 21:
 * Add 3D Graphics built on top of matplotlib
 * Fix & re-optimize tachyon plotting
 * Generalize interface with plot3d(f, ..., style='tachyon') to place camera & light sources apppropriately, etc.

 * [:graph: Main Project Wiki]
 * [:graph_survey: Existing Software] list; also includes links to several algorithm pages; list is now (/will never be) complete.
 * [:graph_benchmark: Benchmarking] Magma, of course, in the lead.
 * Robert Miller has interfaced NetworkX's XGraph and XDiGraph, and has implemented 2d plotting.
 * [:graph_generators: Graph Generators]: Emily Kirkman is currently creating a class of constructors for common and named graphs.
 * [:graph_db_survey: Survey of Existing Graph Database Software] Plans are in the works to build (or wrap) a large database of graphs. Here is the current list of what I've found. Feedback is especially appreciated here.
 * [:graph_database: Graph Database]: Jason Grout's SQL lite graph database of graphs on up to 9 vertices is on its way!

 * RDF, CDF are done. Are matrices / vectors?
 * Wrap more special functions, add to sage.misc.functions...
Line 57: Line 34:

Core arithmetic team

[:DavidHarvey:David Harvey], ["Martin Albrecht"], Joel Mohler, Robert Bradshaw, [:WilliamStein:William Stein]

  • Develop new __mul__ semantics for rings/algebras using something like ToyQuarternionAlgebraElement as a test case.

  • Write up more entries in WritingFastPyrexCode. (everyone)

  • Write a benchmarking module or improve on the existing one.
  • Optimise pyrex in coercion module.
  • Make Algebra _base_ring into a cdef attribute. This will make it possible to give a fast pathway for scalar multiplications.

    • Rewrite polynomials over Z and Z/nZ using direct NTL calls. (David)

  • build [:MallocReplacements:omalloc] as a shared library (or link it statically to memory.so the Pyrex wrapper) and make sure as much stuff as possible uses it (SAGE_malloc macros, GMP, etc.)

3D Graphics

Robert Bradshaw, Alex Clemesha, Robert Miller, Tom Boothby ...

Graph Theory Implementation

Emily Kirkman, Robert Miller, Bobby Moretti, Tom Boothby

  • [:graph:Main Project Wiki]

GSL

Josh Kantor, William Stein, Tom Boothby

Teaching
