| * Migrate {{{_add_}}}, {{{_mul_}}} etc to new {{{_add_sibling}}}, {{{_add_sibling_cdef}}}, framework etc. Intention is to eventually remove {{{_add_}}} everywhere. * Change all {{{__add__}}} methods (etc) to use new fast code pathways, pyrex tricks, as studied at SAGE Days 2. * Try changing {{{a.parent() == b.parent()}}} conditions to {{{a._parent is b._parent}}} in various places and see what breaks. |

| * Make Algebra {{{_base_ring}}} into a cdef attribute. * Move univariate Polynomial class down to Pyrex, and make it inherit from {{{CommutativeAlgebra}}} instead of {{{CommutativeRing}}}. (''David'') * Rewrite polynomials over Z and Z/nZ using direct NTL calls. (''David'') * Optimise new integers mod n code using fast pyrex tricks. * Make GivaroGFq the default finite extension field implementation ([:MartinAlbrecht:malb]) * Wrap NTL finite extension fields (order $\geq 2^{16}$) and polynomials over finite fields. * Linear algebra (perhaps William or Robert want to say something here?) ==== Lower priority issues ==== * Make generic dense polynomial class in pyrex using C arrays to store coefficients? |
* 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.) |

| == Notebook/web team == Tom Boothby, Alex Clemesha, 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 == 3D Graphics == Alex Clemesha, Robert Miller, Tom Boothby ... * 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. |

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.)
