| * 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. |

| * Optimise new integers mod n code using fast pyrex tricks. * Make GivaroGFq the default finite extension field implementation ([:MartinAlbrecht:malb]) * 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. * 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? == Making SAGE Releases (Packaging and Integration) == . William Stein * Getting sage-1.4.1 ready: * New maxima, pari, clisp. * Editing and including axiom interface. == Interfaces == . William Stein, Bill Page * (done) Axiom -- Bill Page (a 0.2 version is done; Stein is integrating it) * (done) MATLAB -- William Stein -- work in progress == 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) |
* 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.) |

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.
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
David Joyner
Documentation
William Stein, David Joyner, Iftikhar Burhanuddin
