| A page to summarise and coordinate SAGE development activity. == 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. * 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. * Optimise pyrex in coercion module. * 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?) ==== 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 * Axiom -- Bill Page (a 0.2 version is done; Stein is integrating it) * MATLAB -- William Stein -- work in progress == 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. == 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] now beginning; purpose is to test construction, storage, retrieval and ''very'' basic functions * currently interfacing NetworkX with SAGE * experts will be contacted regarding a) the completeness of the list, b) the best benchmark tests * ''thorough'' benchmarking to begin soon: we will set up another wiki for results * after benchmarking, the real fun begins... == GSL == Josh Kantor, William Stein, Tom Boothby * RDF, CDF are done. Are matrices / vectors? * Wrap more special functions, add to sage.misc.functions... == Other groups add yourselves here == |
