| A page to summarise and coordinate SAGE development activity. == 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. * 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. * 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. * 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]) * 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) == 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. == Graph Theory Implementation == Emily Kirkman, Robert Miller, Bobby Moretti, Tom Boothby (eventually) * [http://sage.math.washington.edu:9001/graph Main Project Wiki] * [http://sage.math.washington.edu:9001/graph_survey Existing Software] list; includes links to several algorithm pages also; list is now complete * [http://sage.math.washington.edu:9001/graph_benchmark Initial Benchmarking] complete. Review our results here. * Robert Miller is currently interfacing NetworkX's XGraph with SAGE. * Robert has also done cool stuff with plotting graphs. * [http://sage.math.washington.edu:9001/graph_database Graph Database]: Emily Kirkman is currently creating a class of constructors for common named graphs. * [http://sage.math.washington.edu:9001/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. == GSL == Josh Kantor, William Stein, Tom Boothby * RDF, CDF are done. Are matrices / vectors? * Wrap more special functions, add to sage.misc.functions... == Teaching == David Joyner, Bobby Moretti * Wrapping Maxima functions and creating Python classes to support Calculus and ODEs. * Creating functions to teach Fourier series and discrete Fourier transforms on various groups. * See [:BasicCalculus:Basic calculus architecture] for SAGE. == Coding theory == David Joyner * Wrapping GAP and GUAVA code to support work in error-correcting codes. == Group theory == David Joyner * Wrapping GAP code and creating Python classes to support work in finite group theory and representation theory. == Documentation == William Stein, David Joyner, Iftikhar Burhanuddin == Other groups add yourselves here == |
