Sage Days 31 Projects

LDAP-based authentication for Sage NB users

• Create an LDAPUserManager for the new flask-based Sage Notebook

• See Notebook LDAP for more detailed notes

• See this warning about the problems with OpenID

Integrating a coding view to replace the current textfield and tiny MCE views

• This was a student project in Math 480 last quarter.
• The project here is to try it out, and see if it is a good idea or if something based on it should be included in Sage. Not clear, due to the "weight" of codemirror.

• Here it is: http://wstein.org/edu/2011/480a/projects/juarez-sean_johnson-priya_chagaleti.zip

• In case you're curious: the other projects

Fix little issues with notebook so it works well standalone

• see this thread for ideas

HTML 5 backend

• People:

• #9471

MathJax

• People: Davide Cervone, Jason Grout

• #9774

• From Nicolas Thiery: would Mathjax be able to support pgf/tikz pictures?

Notebook Logging

• People:
• Make it so the log files get rotated and compressed. Support or use some standard tool.
• Make it so log files contain something useful, and are configurable.

Database: SQLite

• People:

The following should *at a minimum* work with SQLite, since that is included with Sage and whatever we do needs to at least work standard with Sage with "zero configuration".

• Store all worksheets in a database
• Store user configuration data in a table
• Etc.

Create a Robust Notebook "System"

• People:
• A script that starts a separate notebook process
• It then starts monitoring the notebook to make sure it keeps running, and does a standard test (e.g., view published worksheet listing, login, create a worksheet, compute 2+2, delete worksheet, log out).
• If it doesn't respond after a preset amount of time with any test, does a configurable action, e.g.,:
  • kills and restarts the server
  • sends emails to the admins

i18n

• People: Mike, Burcin

• port the internationalization patches (#9428) to the new notebook

Jmol Update

• People: Jonathan Gutow

• #11080

• #9238-new Jmol.spkg 6-14-11

• #11078

• This can be tested on IanSR's LDAP-based Sage Notebook which is available here, but to use this you need to create an account on our system here. This is a single form, with email confirmation. You should use institutional email addresses, not gmail, hotmail, etc. as those accounts will be purged from time to time.

• Instructions for getting flask with all updates running.
  1. More painful option: try following things from ticket #11080 (link above).
  2. Should be easier, but won't give all the latest from flask updates.
     1. Pull the flask notebook from

https://gutow-flask.googlecode.com/hg/

• b. SPKG that moves Jmol out of the notebook

./sage -f "http://www.uwosh.edu/faculty_staff/gutow/Jmol_for_SageNoteBook-1.1.7.spkg"

• c. Apply patches that affect Sage (but not the notebook). See #11496 and #11503.

Quantumino Puzzle Solver

Solve the the puzzle with Sage so that less people lose time to solve it by hand and make them work on the Notebook.

• People: Sébastien Labbé

• The problem : Quantumino Puzzle

• The solution : #11379

notebook to and from other formats

• People: Rob Beezer, Bruce Cohen, Sébastien Labbé

sws2tex

• see its bitbucket site

sws2rst

• see #10637

rst2txt and rst2sws

• see #11459

• You may test it on this file: ReST file

You can now upload a ReST file in the Sage Notebook to get a worksheet.

Also, from the same ReST file, you can create an HTML file by using the docutils command rst2html. During the week, I was able to make MathJax work on this HTML output. See this page on my website for more info.

Notebook Administration Issues

• People: William Stein
• Write an improved script for monitoring the health of a notebook server.
• Move all the notebook servers to one single account on one computer. In particular, the sagenb0 virtual machine on boxen crashes completely every few days, which is a major pain in my (=William's) arse. Also, all servers should be running sage-4.7 and a flask-based server.
• Experiment with having a virtual machine just for running user code (and nothing else).

The mysterious moving/disappearing text bug

• People: Ryan Grout, Jason Grout, John Travis
• Find a reproducible one (Found)
• Fix it (Possibly?)
  • (The issue we found was with the TinyMCE autosave plugin. We fixed it by just preventing the plugin from loading)

Geogebra integration

• People: Bruce Cohen, Rob Beezer, Rado, Mike Gage, Keshav Kini

• Confirm proof of concept at #7489

• Bruce: We looked at #7489, but I was not satisfied with the output. Rado showed me how he used <iframe> for graph_editor.

• The webwork people (Mike and Jason) have taken the iframe() function and will use it in their work. I should open a new ticket to put iframe() into Sage. It is more general than #7489.

• Opened #11489 to include method html.iframe(). My thanks to Rob and Keshav for helping this newbie with the process. Take a look at html.iframe() for my current work.

Folders, Tags, Hierarchies

• People: Rob Beezer
• Provide organization to list of worksheets
• Give worksheets identifiers that allow cross-worksheet links

• #7665

• #1496

• R Beezer: I think there is at least one more ticket out there, using a Javascript tree library to do this, but I cannot find it.

Sorting lists of worksheets

• People: Rob Beezer
• Sort lists of worksheets based on creation time, modified time, tag, alphabetical

Various proposals for notebook enhancements

• People:

• sage-notebook Post

Configure cell "skip-ahead" behavior

• People: Rob Beezer

• sage-notebook Post

Widget Infrastructure

• People:
• Create a general way to easily incorporate (Javascript) widgets, such as existing Tiny MCE editor and graph editor or rumored matrix editor, equation editor, function palette, etc

• #9585 (Davide Cervone)

Notebook Code Site Issues

• People: William Stein (maintainer/owner)

• http://code.google.com/p/sagenb/issues/list

Create better documentation for files of notebook

• Create wiki page for draft of where to find templates, cell commands, login protocols, etc.
  • Idea is to have a one-stop shop telling to find any given thing in notebook
• Move to developer guide in basic ReST style

Comparison of number field elements

• People: Robert Bradshaw, Mike Hanson, Burcin Erocal

• Fix issues related to the (broken) ordering of number field elements: #6132, #7160, #10062, #10064, #10849,

Symbolics

• A bunch of issues related to symbolics, mostly based on user requests.

Documentation

• People:

  Document the relation between pynac <-> Sage and how symbolic functions work. Can be divided into 3 parts:

• Generic design explanation in sage.symbolic

• pynac and using Python objects in numeric objects

• Symbolic functions

add more symbolic functions

• People:

  Use the symbolics framework to implement special functions. This involves writing methods for symbolic evaluation (for example sin(pi) -> 0, differentiation, wrapper for numeric evaluation, etc.). See the trac wiki page. See #11143.

Long standing symbolics issues

• People: Burcin

• segfaults caused by ordering issues in pynac #9880

• Dynamic attributes for symbolic functions #9556

Sage Days 31 Tickets Needing Review

• Temporarily disable '@' symbol in username because it breaks TinyMCE #11343

• Merges in Flask - Use SAGE_TEMPLATE_PATH for custom templates #11106

• Upgrade Mercurial: #10594; the new spkg file comes with fixes for #11121 and #11120 which also need review.

• Easy documentation fix for top-level solve: #10444
