| * 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. * Wrap NTL finite fields and polynomials over finite fields. * Benchmark omalloc. (''Martin'') * Linear algebra (perhaps William or Robert want to say something here?) |
* 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.) |

| * 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 |

Hi! The page you're looking for probably would be devel, but hey, you're here.
A page to summarise and coordinate Sage development activity.
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.

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.)
