Sage Days 31 Project Ideas

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

• #9238

• #11078

notebook to and from other formats

• People: Rob Beezer, Bruce Cohen

• sws2tex - see its bitbucket site

• sws2rst - see #10637

• rst to notebook - see #11459

  • Note from Sébastien Labbé: I would like to polish up and merge into Sage a script I wrote this winter to translate .rst files into notebook (txt) files. It is based on the file docHTMLProcessor.py which is part of the sage notebook. Although, since there are always rumors that the Sage Notebook is changing, I did not push it any further and was waiting for the new version of the Notebook before. The script (rst2notebook) is available in the misc directory of the sage-combinat hg server.

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:
• Find a reproducible one
• Fix it

Geogebra integration

• People: Bruce Cohen

• Confirm proof of concept at #7489

• Make some progress figuring out how to actually get it into Sage in new notebook

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
