[sage-devel] Re: checkpointing enumeration of points on hypersurfaces in toric varieties
IMHO checkpointing (=saving the state at regular intervals) is important in any kind of long-running computation. Assuming that we can pickle the iterator, it would be easy enough to have a @parallel(checkpoint=/path/to/directory) decorator that saves the progress in regular intervals and restarts if necessary. If there are multiple parallel loops then it can be a bit of a hassle to identify the right one (and/or change @parallel inside library code). So the more useful version would be a context with checkpointing(/path/to/directory): do_some_computation() Mini-intro on the new generic (slow but oh so useful if you just want an answer) point counting: sage: P2.x,y,z = toric_varieties.P2(base_ring=GF(5)) sage: pts = P2.subscheme(x^3 + y^3 + z^3).point_set() sage: list(pts) [[0 : 1 : 4], [1 : 0 : 4], [1 : 4 : 0], [1 : 2 : 1], [1 : 1 : 2], [1 : 3 : 3]] sage: pts.cardinality() 6 sage: i = iter(pts) # define an iterator sage: next(i)# stop at the first found point [0 : 1 : 4] sage: next(i)# second point [1 : 0 : 4] sage: next(i)# third [1 : 4 : 0] On Thursday, May 28, 2015 at 8:41:16 PM UTC+2, Ursula Whitcher wrote: While discussing Ticket 16953, which improves functionality for enumerating points in toric varieties over finite fields, I said: The actual functionality works fine, albeit slowly.

[sage-devel] MathJax limit for TeX expression in notebook
Dear Sage Devs, I have a question related to the limited length of a TeX expression rendered by MathJax in the notebook - the variable responsible for it is MAXBUFFER [1], and its default value is 5*1024 (5KB), which in most cases is quite all right but sometimes, for example when printing tensor components in SageManifolds (sagemanifolds.obspm.fr), it's not enough. Is it possible to pass a MathJax preamble in the notebook? Or alternatively, can we have MAXBUFFER increased in Sage local/share/mathjax/config/TeX-AMS_HTML-full.js default configuration?

VentureBeat: Talk about adoption at web companies and growth in the SageMath community in general. SageMath, Inc: I have little information about how or if web companies use SageMath. Whenever I suggest to people at such places that they don't, they usually provide counterexamples. And when I meet random people at tech meetups... they often know about SageMath or have even used it some in their tech work.

[sage-devel] How does trac's automerging work?
Hello, I frequently see red links on Trac git branches with the message trac's automerging failed. But when I try to merge with latest develop using the git command line, the merge succeeds without conflicts. Why is this? What does the Trac git plugin do to merge? And a different problem is that ticket dependencies aren't taken into account, but I know I lost that battle long ago.

The commandline git client is better at merging, so sometimes it succeeds where pygit2/libgit2 fails.

Is the current behaviour a result of long discussions and thought? Should more people chip in before we rush in and change this? For your sided question, the fastest way is to use Element._set_parent() ... Ok, thanks. The question in your case is rather do *you* *want* that the elements have parent the linear code? Ok, clear explanation and very good question. I certainly don't want the parent to be the vector subspace (as now); it should either be the full vector space or the code. I think the former makes most sense, but that's due to the same logic as above for vector subspaces...

[sage-devel] Re: documentation bug: git-trac instructions don't mention git commit
I won't recommend '-a'. Explicit addition of files using 'git add' is safer as to you do not accidentally push too much upstream... I 100% agree, esp. since sometimes there are extra changes lying around - one of the few places I like git better than Mercurial. I think I mentioned something along these lines in the sagenb release instructions, and if someone cc:ed me on a pull request to add info about that to SageMath's, I'd review that. -- You received this message because you are subscribed to the Google Groups sage-devel group.

[sage-devel] Re: Strange bug in poset plot
This is because the graph is relabelled before being send to plot. You must
give the new labels as values for the coloring dict.
sage: D = Poset(( divisors(12), attrcall(divides) ))
sage: mb={x:D.mobius_function(x, D.top()) for x in D}
sage: labels={x:(x, mb[x]) for x in D}
sage: v_colors={red: [e for e in D if mb[e]0], gray: [e for e in D if
mb[e]==0], blue: [e for e in D if mb[e]0]}
sage: v_colors={red: [labels[e] for e in D if mb[e]0], gray:
[labels[e] for e in D if mb[e]==0], blue: [labels[e] for e in D if
mb[e]0]}

[sage-devel] Re: Posets, is_sublattice()
Hey Jori, I would have one method called is_sublattice() which takes some kind of set and checks if that set of elements forms a sublattice. You could then specialize this by checking the type of the input to see if it is a lattice, and if so, only check element containment.
