[sage-support] Re: non-english characters in Notebook
Well, no luck with direct workaround. If I change %u0441 to #x0441;, it shows correct char *for this only session*, but on save+load, it gets replaced by even more non- english char (like euro sign :-) You're right, this seems caused by how worksheet is saved/loaded. The only way of indirect workaround I can think of so far is to load worksheet into html frame and constantly do %uN - #xN; replacements with Javascript. BTW, how can I add multiple lines comment in Notebook? So far, the 2nd line is discarded. Also, if I create a comment-only section, it's discarded on save/load. I'm just trying to make text-only (no math) block. --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://sage.math.washington.edu/sage/ and http://sage.scipy.org/sage/ -~--~~~~--~~--~--~---

Could you summarize the situation with rendering problems? Is it as follows:
(1) When you try to put them in input cells, they get corrupted on load/save.
(2) Using edit mode, unicode not in {{{}}}'s gets saved just fine.
Oh, by the way, when you're entering html in edit mode, you can just do,
e.g., consider $y^2 = x^3 + \sqrt{x}$ and the formula will get typeset
using jsmath.

Yes, as they are NOT processed (as I understand) and get saved as

Yes there is, and you might even find this impressive:

Use it:

Wow, this makes it seem like doing the following is a clear violation

Wow, gee, I never thought about this one. It's definitely a web server
here. You are the licensee, but the wording without limitation makes
it sound like it's even forbidden to do this on a single-user license if
you bought the software.
It sounds like we do need some official clarification at this point.
Keep in mind that the other license agreements (like the Network license
agreement) probably have different terms.
Jason: Could you take responsibility for writing to Mathematica about this?
Then post the response?Feel free to specifically mention Sage.
Sure.
I'd really like to know if the Mathematica license is really that restrictive.
If so, I want to add a disclaimer about this to keep from getting into

That's coming from a newline, which appears in Mathematica 5 I guess,
but not 6. Anyway,
the patch I justed posted at
http://trac.sagemath.org/sage_trac/ticket/1491
fixes the problem. Alternatively rewrite the function like this:
sage: def math_bessel_K(nu,x):
return sage_eval(repr(mathematica(nu).BesselK(x).N(20)).replace('\n',''))
Important note: The conversion from Mathematica to Sage, i.e.,
mathematica_object.sage()
is very naive still -- all it is is basically sage_eval(repr(...))!
This could/would be improved
if somebody cared a lot.

[sage-support] Call for developers: Looking for FAQ maintainers
Hello, Sage has an faq at http://wiki.sagemath.org/faq It is a rather young wiki page (first real content 2 weeks ago), but it has been growing rapidly due to the influx of more users because of all the recent publicity. I have been trying to add every interesting question that I see on sage-newbie, sage-support and sage-devel, but my other Sage duties often get in the way. So here is your chance to contribute to Sage. This job doesn't require much knowledge about Sage, just some people to spot interesting questions and add them to the page. All you need is to register yourself in the wiki and you are ready to go. Here are a couple things that should be done: * Add content as it comes up :) * Give the FAQ more structure, i.e. add sections about general issues, notebook issues, installation issues, OSX specific issues, you get the idea * Figure out a way to get the faq into the main documentation in an automated way. This is more advanced, but should be done sooner rather than later. If anybody sees a question that has been answered in the FAQ please point the person politely to the FAQ entry. If any additional questions or comments come up please add them back into the FAQ. Sooner or later google should find those pages if people search for problems.

Just extract the appropriate binary from here on one of them: http://sagemath.org/SAGEbin/apple_osx/intel/ and make sure it fully works -- do make check!!

This will only work if they are running ssh servers, which maybe they aren't? William I would either recommend rsync or NFS to do that job. NFS is less work, but if your network is wonky you will be in for a world of pain. In addition startup times of Sage will likely go up by a lot. rsync on the other hand is a little more work, but if you combine cron and rsync to run some off duty hours that shouldn't be a problem. When I did sysadmin work I always preferred the rsync solution over NFS due to better reliability and better performance. Apple itself has some software deployment tool, but I don't even remember the name of it, so somebody else who knows more about it should let us know. We should also write some chapter with example scripts for the documentation, since I am sure this issue will come up again.

[sage-support] Re: command line install of OS X binary
Its a pretty heterogeneous package for bioinformatics; there are lots of modules that do lots of different things, written by different people. Because of that, as with sage, there is some redundancy in function that is slowly being weeded out. There are only about 5-10 very active developers at the moment though (at least that is my impression). As the name implies, its all written in python. To some extent, it imitates the more widely used BioPerl modules; perl has a big lead in bioinformatics but I believe that is a historical artifact and the superiority of python will eventually make it prevail :) I mainly use it for its parsing and database functions - for example, to retrieve a ferritin protein sequence from a 13-lined ground squirrel (Spermophilus tridecemlineatus) from GenBank: from Bio import SeqIO from Bio import GenBank gi_list = GenBank.search_for(Spermophilus[orgn] ferritin) record_parser = GenBank.RecordParser() ncbi_nuc_dict = GenBank.NCBIDictionary(database='nucleotide', format='genbank', parser=record_parser) record1 = ncbi_nuc_dict[gi_list[0]] print record1.sequence print record1.comment ...but there are lots of other functions for manipulating dna, rna, and protein sequences, dealing with hidden markov models, 3D protein databases and files, scoring matrices, neural networks, coalescence... If that's not sufficient let me know. -MH On Dec 13, 7:03 pm, William Stein [EMAIL PROTECTED] wrote: On Dec 13, 2007 4:27 PM, Marshall Hampton [EMAIL PROTECTED] wrote: Excellent! Thank you!
