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. (hmmm... I don't know if there's much point to this. I can't think of any cases where such fast access to the base ring is necessary.)
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
- 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
- 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] 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...
