Re: [sage-combinat-devel] Re: tickets 10632 and 10485
Do you have the latest version of #10632 since I changed this on Friday and made the KR crystal use the new CrystalOfTableaux code instead of a tensor product. Oops, I had overlooked that there is a new version of #10632. With the current versions of #10732, 10632 and 10485, the only failed tests are the ones in sage_object.pyx that I mentioned in my other message. Ok, it might be good if an expert could confirm that these errors have to do with the pickle jar. I tried to input things like shape = [(2*s+1)/2,...] in the KR code, but then sage complained. I do not know why. So now I use shape = [s+0.5,...] and I suppose this is why the output is with 0.5 instead of 1/2. If you import QQ from sage.rings.all, then I think you can: shapes = [ [i+QQ(1)/QQ(2) for i in sh]+[QQ(1)/QQ(2)]*(r-len(sh)) for sh in shapes ] Thank you.

[sage-devel] Re: FAQ suggestion: I'm a programmer, how can I contribute to Sage?
I respectfully disagree with some of the comments about copy editors.
One doesn't need to be a mathematician or an entry level programmer
to recognize that the installation guide is;
a) one of the first documents that many SAGE users use.
b) in need of some edits, particularly with respect to the sequence of
operations.
A good, even fair, copy editor would recognize this and could produce
a much more usable guide with little more than copy/paste.
Even I am able to point to passages that need to be moved before other
passages, e.g. setting environment variables PROBABLY needs to be
moved
earlier.

[sage-devel] sage -b doesn't rerun Cython on quaternion_algebra_element.pyx
This is a problem I discovered when upgrading from sage-4.5.3 to a candidate 4.6.2.alpha4. Probably, the problem has existed for a while, it just surfaced or got noticed now. The problem is that the file sage/algebras/quatalg/quaternion_algebra_element.cpp is *not* recreated from the corresponding .pyx file when upgrading. This then causes a compile error. The file sage/algebras/quatalg/quaternion_algebra_element.pyx includes (using Cython's include statement) sage/ext/gmp.pxi and the latter file was changed some Sage versions ago.

On 2011-Feb-06 11:13:57 +0100, Burcin Erocal bur...@erocal.org wrote: I am not sure what the speed of the cephes implementation is compared to that of the C library though. The float evaluations are used for plotting, so any slow down in the numerical approximation of these functions will degrade plotting performance significantly. Note that cephes is used to implement functions that aren't available in the base system libraries and an implementation that exists is going to produce better results than one that doesn't. As for speed, if that's a concern, I suggest you try some benchmarks. But note that correctly handling all the exceptional conditions available in IEEE754 and providing accuracy to 1 ULP or so can mean the code is slower than a sloppy implementation - and I'm aware that some libm implementations have some quite sloppy code. Whilst plotting probably doesn't require much precision in most cases, other uses of libm functions do expect precise results. On another note, if Cephes is only included for the evaluation of these few functions, I am not convinced it should be shipped in the standard distribution. There are quite a few libraries already in Sage, which have this capability. For example, can't we just use GSL to evaluate gamma on Cygwin? One issue is that Sage expects that the gamma() family exists in libm, similarly with the other libm functions. If they are implemented elsewhere, this is likely to require changes to header includes and linking for some libraries. There's the associated problem of identifying the functions that are either missing or inadequately implemented in the host libm and locating alternative implementations within Sage. It's also worth noting that this is the 3rd platform where cephes is needed - it was initially introduced as part of Cygwin support. I've found it necessary for the FreeBSD port and now it seems necessary for the ARM port. If you want to start de-bloating Sage, there are lots of other low-hanging fruit. Note that since FreeBSD is gradulally implementing the missing parts of libm, the functions that are needed from cephes (or equivalent) changes between FreeBSD versions. #9543 therefore includes scripts to only select those parts of cephes that are missing from the base OS. It also provides some include and linker trickery to make the split of functions between two libm.so files transparent to consumer apps. -- Peter Jeremy pgpHFCeDV9fcG.pgp Description: PGP signature

[sage-devel] test Flask-based notebook
We need people to test the new flask-based notebook that was done at the January Sage Days in Seattle (I believe mainly by Mike Hansen, Rado Kirov, and Dan Drake).

Most grant proposals and other requests for funding have very specific plans, people, timelines, etc. attached to them. I realise that. However, it's also highly likely the individuals reviewing the grant applications would look on the Sage web site. In light of your (and other people's) concerns, I think it would be very good if there were a more central location to see this, what people were working on, and status reports. I would add to that 1) What the goals are, even if there is nobody working on them. Two obvious advantages to having this would be: * It could attract a student to work on a project, if he/she knows it is a goal, but nobody is working on it. * It could attract a commercial company to sponsor a particular piece of work if they realised one of Sage's goals would be beneficial to them. 2) Archive the status reports - move them from a Wiki to a read-only section of the web site. Just like the FreeBSD does. http://www.freebsd.org/news/status/report-2009-04-2009-09.html http://www.freebsd.org/news/status/report-2008-10-2008-12.html http://www.freebsd.org/news/status/report-2008-07-2008-09.html This would help get more realistic estimates of time for different tasks. Predicting times for software development is notoriously very difficult, even when people are paid to do the work. But making predictions based on the times to do similar work is one of the standard methods. It's not perfect, but is one of the better ways. With expereice of porting Sage to Solaris, I'd have a much better idea of the times to port to AIX or HP-UX. I may have come across as portraying sage development as too individualistic--much work is done by individuals, but the level of a single grant with one or more PIs, their collaborators, students, etc. with clear-cut goals and timelines has provided a good level of organization that gets things done, but the funded grants tend to be of narrower focus than all of Sage. Grants applications should have well defined goals - if not they would never be funded. A steering committee might be a good idea, we have JSage which somewhat fulfills this role. As a closed group, I think many of us would appreciate more openness, for more people to have an input. But ultimately William started the project, so he should have by far the most say of the goals.
