Re: [sage-combinat-devel] Re: Categorification of tableaux
Hi Jason! For once, I am trying hard to procrastinate on the Sage-Combinat e-mails in order to focus on finishing our paper with Florent and Anne, instead of the converse; hence my slow answer. Thanks for your long post! It sounds all fine to me. I'll just insert a couple micro comments below. I hope someone goes on and implements this! It would be great if you could do with Andrew as reviewer (or the converse, or with whatever pair programming scheme fits you).

Currently in Sage, those two gadgets are usually distinct (think Partition/Partition_class which makes it inconvenient for the user to access Partition_class, say for an isinstance test. class Tableaux(UniqueRepresentation, Parent): ... class SemistandardTableaux(UR, Parent, Tableaux): # similar class StandardTableaux(UR, Parent, SemistandardTableaux): # similar No need to specify again UR and Parent; those are inherited through Tableaux. Finally we have the specific parent classes. I think they should look roughly as follows. The parent classes class Tableaux_all(Tableaux): def __init__(self): super(Tableaux_all, self).__init__() # I don't know a good category, since general tableaux (which # allow, for example, real-number entries) are not enumerable. I guess Sets() is the best we can do. class SemistandardTableaux_all(DisjointUnionEnumeratedSets, SemistandardTableaux): def __init__(self): DisjointUnionEnumeratedSets.__init__( self, Family(NonNegativeIntegers(), SemistandardTableaux_size), facade=True, keepkey = False) # Note that I'm not clear on what facade and keepkey do. # They may not be necessary or advisable. * With keekkey = True, the elements of the disjoint union would be of the form (5, Partition([3,2])). That's only useful when one wants to construct the disjoint union of a collection of sets which are not originally disjoint (e.g. building n copies of a given set). * facade = True/False controls whether, for x in SemiStandardTableaux(), x.parent() is SemiStandardTableaux() or SemiStandardTableaux(shape=...) class SemistandardTableaux_size(SemistandardTableaux): def __init__(self, size): super(SemistandardTableaux_size, self).__init__( category = InfiniteFiniteEnumeratedSets()) Interesting category :-) But yes, the category should be set to one or the other depending on what makes sense.

Bruce wrote: Thanks Dan. I would be happy to try if I knew what to do! In order to try the patch (short of waiting for the patch to get merged into sage) you need a patched version of sage. Can you compile sage from scratch? That is, download sage-4.5.2.tar from here: http://www.sagemath.org/download-source.html Then compile the program by the instructions on that page. It is assumed you have either a Mac or a Linux machine. If you can do this, you can patch the program and then recompile it. That may require further help from us but it is certain that can be done if you are able to build sage from scratch. If this is difficult you can meanwhile avoid style=coroots and have coefficients in a polynomial ring.

When you want to explore a mathematical topic programmatically you don't need to start from scratch.

You can write what interests you and pull in great code for the parts you need but can't write or don't want to write. And when it is wrong (not if), you can isolate the problem, and if you can't fix it, there's a good chance somebody else will care enough to fix it. Sometimes even promptly. And in the process Sage gets incrementally better. That's the beauty of Sage for me and I don't believe it can be said about any other project.

Re: [sage-devel] Re: Random banter about Sage standards
I think the claim was that it is becoming the M$ of mathematical software. I suspect that means default standard or something. Actually, I didn't ask. Tim, what does it mean? I was making the assumption that Sage managed achieve success by being widely adopted and replacing the 4Ms. The bulk of the discussion rests on that assumption. If that assumption is not true and Sage disappears, nobody cares.

Re: [sage-devel] Re: Random banter about Sage standards
If I understand you correctly, you want to set the goal for Sage much higher than just a free, open alternative to the Ma*s. - Robert Yes, but why am I trying to do that? Computation mathematics is a new field of study, at least in the symbolic area. It is the child of the union of mathematics and computers. Unlike other forms of software, computational mathematics software (CMS) has the property that it will always be able to give timeless answers, making it useful forever. Being useful forever does not imply that the software survives forever. You can argue that this is good darwinian attrition. But CMS software is very hard to build and requires a great deal of very scarce expertise that can disappear at any time (e.g. changing jobs, being hired into a company like MapleSoft/Wolfram/Magma/etc., companies being bought or closed) When that happens, and it will, then that portion of the software becomes unmaintainable or unavailable. The natural response to dead software is to write new software. You can see this in CMS-land as there are over one hundred attempts at building CAS programs (I collected them at one point, similar to the Sage goal). But due to the expertise issue these programs don't get very far. Sage wants to rewrite the Trager/Bronstein integration but that seems unlikely as the required expertise (Bronstein) is dead and the code isn't documented (yet). Sage is trying to avoid the darwin problem by gluing together existing systems. This is a very clever idea, a second generation response. What I am trying to do is ask the question... What does a computational mathematics system need to do to live forever? in particular, in this forum, What does Sage need to do to live forever? Sage is exciting, fast moving, has no time to do it right, would die of documentation ossification, couldn't possibly prove anything (as if proofs are foreign to mathematics), needs to be released twice a day, is in a foot-race with the 4Ms for mind-share, needs quantity not quality, will let the next-generation-slubs document their work, is 3ns faster than M*, etc. I am one of the first generation dinosaurs trying to impart some of the lessons learned to the next generation. I am taking the long view, trying to figure out how to impart computational mathematics to my grandchildren. Will they still be writing new polynomial packages and arguing over ZZ? Will they have to watch yet another hundred threads discussion the same issues? Will they suggest that William Stein should move his comments to the flame thread? Or will they have a broad legacy of excellent CMS work upon which to build? My experience tells me that William will move on, python will move on, the funding will dry up, the students will be hired into real jobs and Sage will die of code rot as GCC/python/architecture/build-complexity/etc all work away at its foundations. The system will devolve into tracking down hard bugs in other peoples code, people will find that hard without documentation and not worth doing because it isn't flashy. Suppose William had instead proposed that Sage was a project to find and fix all the bugs in Maxima. How many people would join? Now imagine Barry Brightspot proposing a project to find and fix all the bugs in Sage To those who work on Sage... Why? Do you just want to build yet-another-CAS? Do you just want a platform for your thesis work? Do you just want to write code that gets thrown away? Or would you rather have your name appear in the credits list of Sage-2090 as one of the Newtons of computational mathematics? I am advocating that Sage set its goals much higher than replacing the Ms. If you don't, then my experience tells me that the project will die. If you do then the project may die anyway but other people can build on the remains rather than from scratch. Or you just might have a formula for the long-term. What do *you* think needs to be done to make Sage live forever? I have thought about this question for a long time and I'm trying to pass it on. Your experience may tell you that my suggestions are wrong but you'll only be able to know after the fact and by then it will be too late. Anyway, I've said about all I want to say so I'm abandoning this topic. Good luck and thanks for all the fish.

I'm uploading a dmg of 4.5.2 made from the current sage -bdist script to sage.math (46% done). I planned on giving that URL to students. Would you suggest giving a link to your dmg instead? The current dmg is probably better until this is tested more. Also, how do I get it to just open up my normal browser (firefox)? I have lots of customizations to my firefox that I'd like to use (for example, tabs on the side, etc.). It would be great if there was a preference item which let me choose between opening up the built-in browser, or opening up the system default browser.

I think his rationale is that it would be nice to Command-Tab between Sage and other browser windows; however, most of us are so used to it running from a server in a regular window that (imho) this should be the default. And adding this to sage-bdist is nearly trivial. We already get your older (much smaller) version with SAGE_APP_BUNDLE=yes, so we just swap this guy (when ripe) into extcode and then make SAGE_APP_BUNDLE=yes default in sage-bdist. - kcrisman -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org

I can't do full-screen with the included browser (at least not as well as firefox). I completely understand wanting to use a real browser—they have all kinds of features I don't envision ever being implemented for Sage.app. I'll go ahead and start coding it up. What you can do at the moment is uncheck Show in Dock in Preferences and it will only show up as a MenuExtra, and will use your default browser. Another way is to forcibly set SAGE_BROWSER in .bashrc since that will override what Sage.app sets it to. That may be a bit much for students though.

The one problem I haven't figured out yet is how to tell when the server has finished launching. Right now I key off the fact that it gives me a specifically formatted URL. I could do polling on the log file or something, but I don't really like that. Is there a way to tell sage to run a particular script (passing the port it's on) when it gets done starting the server?

Re: [sage-devel] ipython pipeline
Hi Jason, On Tue, Aug 31, 2010 at 7:13 AM, Jason Grout jason-s...@creativetrax.com wrote: Fernando, if you're reading this: I'm curious if you have any thoughts on how the Sage notebook might be impacted by this. The notebook itself, not at all: sagenb doesn't use any ipython code itself. It has features that ipython introduced, like the formatting of the ?/?? output, or the use of the % syntax for special commands --though with different semantics to IPyhton's magics, but all of it is a separate implementation based on Twisted. In the long run, if our approach works very well, and sage wants to move away from twisted (one of the reasons we want to leave twisted is for python3 support), sage could decide to use this ipython as its backend and expose its own app semantics to its notebook. But it will be a while before that needs to be considered. In the short term, the bigger benefits would be to terminal-based users: these new, richer local clients for ipython (two-process terminal, curses-based, Qt-based) are all 'just ipython', and in that sense could be used by Sage too (assuming it shipped the dependencies, like Qt and zeromq). The sage command line is a customized ipython, so sage could equally decide to customize this new ipython and expose a new set of local clients to run sage locally.

On 08/30/10 09:51 PM, Robert Bradshaw wrote: On Sun, Aug 29, 2010 at 3:47 AM, Dr. David Kirkby There are two different goals that people have here. One is to build a solid, bug free piece of mathematical software, ideally conforming to all the good software engineering principles, building everywhere, well tested, etc. The other goal that people have here is to make Sage into something useful for their current research and teaching needs. While these two goals certainly complement each other, they have vastly different priorities. IMHO, if Sage is to be a viable alternative to the 4M's, it needs to address the former. If so, what should we do better? * I think a good start would be to try to attract some compute science students to do some projects looking at how quality could be improved. In essence, I don't believe Sage has the right mix of skill sets. Welcome, all CS students! On a more serious note, we have had one CS student look at the security of the notebook for a master's thesis, but more would be nice. That's something William and others need to actively seek out though - ask in CS departments. One CS student project is useful, but that must be a very small fraction of the total number of student projects. He can buy me a copy of http://www.amazon.com/Software-Engineering-9th-Ian-Sommerville/dp/0137035152/ref=sr_1_1?ie=UTF8s=booksqid=1283077786sr=8-1 if he wants. Some of what we do may be due to ignorance, but, as I've said before, it's often a question of allocation of resources (mostly time). But if anyone is going to spend a lot of time doing something, it would make sense to reduce ones level of ignorance. I believe the time/effort used to find out how to write better software, would reap benefits in the medium and long term. * If there was funding, then pay someone with a strong background in a commercial environment with knowledge of how to develop software. Someone good would cost a lot of money. He/she should be interviewed by someone who knows the subject well. Perhaps ask a prof from the CS dependent to be on an interview panel. If there was funding, most people would probably rather spend it on someone who could develop new algorithms to further the state of mathematical research. If there were funding for many people, perhaps a percentage could go to funding someone with as CS background just to focus on software development issues. I suspect you are right - people would rather spend the money on someone developing algorithms. But what area? Ask 20 random Sage developers and you are likely to get 15 different answers. I think this was clear when William tried to get a list of the most annoying bugs. There were barely any common ones. People have different interests. As such, an extra person working on algorithms in field X is probably only going to benefit a small fraction of the Sage community. In contrast, someone whole could improve the procedures could benefit everyone. A year spent cleaning up Sage's procedures would benefit everyone - a year spent developing algorithms would probably have far less overall positive impact. * Have regular bug fix only releases, where the aim is just to increase the quality, and not to add features. Nathann Cohen has said -1 to that idea. William has said it would put people off, and at least one other developer (forget who) did not like it. But I feel it's probably one of the easiest ways to improve Sage. I'm unconvinced that this would help, and agree it could put people off. We could bump all non-bugfix tickets to the next release but I don't think it'd increase the actual number of bugs fixed. (Bug-fix Sage days work well though.) By bug-fix release, I should elaborate. I would include * Bug fixes * Added documentation. * Extra test code I think having releases where new features were not introduced, but those three areas were addressed, it would result in a concentrated effort to reduce the bugs. But, that was NOT the main reason for suggesting it. My reason was that basically by having 'bug fix' releases, you would create some releases which are more stable than others. Those would be more suitable for people who don't want to keep upgrading every couple of weeks. They might chose to have stability in preference to features. I believe there are a lot of people in that category. * Have a system like gcc, where the releases numbers x.y.z mean something. Only have z != 0 on bug-fix-only releases. Make it clear on the web site that the the x.y.0 are less well tested. +1 But to do that effectively, one needs to have bug-fix only releases - just like gcc does. * Make release candidates available for anyone to report on. +1 I was pretty sure you were against that a few weeks ago - saying they should subscribe to sage-devel and would be aware of them. Perhaps it was someone else. Sorry if I'm mistaken. I think making the release candidates public for a couple
