 * 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.)
 * Wrap NTL finite extension fields (order $\geq 2^{16}$) and polynomials over finite fields.
==== Lower priority issues ====
 * Make generic dense polynomial class in pyrex using C arrays to store coefficients?

 * 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 33: 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.

Caution

Instead of this wiki page, the development team now uses Sage's trac installation at http://trac.sagemath.org - please use trac and move open issues there.

Core arithmetic team

David Harvey, Martin Albrecht, Joel Mohler, Robert Bradshaw, 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 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

GSL

Josh Kantor, William Stein, Tom Boothby

Teaching

David Joyner, Bobby Moretti

  • Creating functions to teach Fourier series and discrete Fourier transforms on various groups.

Coding theory

David Joyner

  • Wrapping GAP and GUAVA code to support work in error-correcting codes.

Group theory
