Sage Tasks Outline

This is a general outline of targeted areas, including specific tasks, for improving the usability of Sage. The sources include the Sage Usability Improvements List and sagenb/todo.txt, but the scope here is wider. Feel free to make changes. To keep items succinct, please make links to group discussions, etc.

General

  • Sagenb.org privacy policy.

  • Y. Aner's notebook threat model (PDF).

  • SageForge - semi-automated repository for contributions to Sage:

    • Scripts, worksheets, databases, and packages of [nearly] all sizes.
    • Supplementary documentation, including multimedia.
    • Optional reviews and ratings.
    • Live, ulimited cellular paste-bin.
    • RSS feeds.

Build / Test

  • Tests:
    • Meaningful statistics / benchmarks, e.g., %timeit for individual doctests.

  • Buildbot.

  • Parallel inter/intra-spkg builds.
  • Windows port.
  • Fat binaries (no SSE3, etc.).
  • Notebook functional tests - Extend Selenium tests to other browsers.

  • Notebook load tests - The Grinder, FunkLoad, Pylot, Watir, Zope.testbrowser (now in SageNB).

Development

Documentation

Notebook: Admin

  • Don't list all users' worksheets.

  • Authentication - abstract interface:
    • LDAP.
    • UNIX accounts.
  • Dashboard:
    • Real-time and cumulative statistics, aggregate and per user.
    • Backups: complete or selective.
    • Manage user accounts, passwords, groups, privileges.
    • Send email to all registered users.
    • Install new / updated modules and spkgs.
  • More powerful account management tools.
  • Allow email address as username.

  • Custom analytics tags, geolocation (ClustrMaps).

Notebook: Introspection

Notebook: "Modes"

Notebook: Under the hood

  • Manage Jmol applet count / memory use - sage-notebook.

  • Use Python's logging facility.

  • Cythonize pexpect.
  • Load-balancing.
  • Offload more work to worksheet processes, e.g., docbrowser generation.

  • Alternate worksheet process implementations: remote, fork, named pipes, memory-mapped files.

  • Client-server and server-server interaction:

    • Load JS / CSS components on demand - Ajile.

    • Server-to-server backups, possibly with authentication.
  • Decouple secure transport from sage. Use OpenSSL(?)

  • Remote access Python API - Google Documents List Data API

    • Manipulate, share, up/download, publish worksheets at a given Sage(Forge) server.
  • Storage:

    • Fix worksheet.autosave().

    • Always retrieve worksheet content from disk on open.
    • Use a revision control tool (e.g., Mercurial) for undo, history, snapshots, etc.
    • File size limit - auto-delete and warn above threshold.

    • Access a user's data directory securely via the new storage API.

    • Handle permissions better for directories, history, output, conf files, etc.

  • Migrate to server / framework: Django, Pylons, Pyjamas, Tornado, etc.:

Notebook: User Interaction

  • Help:
    • Reorganize help page:
      • Search for commands.
      • Linking to similar and related commands.

    • Easy set up of shipped jsMath fonts - MathJax.

    • Automatic tips for keyboard shortcuts, editing features, etc. Opt out.
  • Customization:
    • Defaults: typeset, implicit multiplication, 3D viewer, rename "Untitled" worksheets.
    • Function to update worksheet titlebar.
    • Easy backups, selective or complete.
  • Keys
    • New shortcuts, e.g., for restart worksheet.

    • Custom shortcuts, e.g., ctrl-bksp to delete previous word, not join cells - #7618.

  • Cells:
    • Right-click menu.
    • Auto-updating cells, e.g., interacts.
    • Unify server and client-side resize algorithms.
    • Always show links for long output cells, regardless of length or interruption.

    • Select, delete, (un)group, move multiple cells.

  • 2D / 3D plots:
  • Worksheets:
    • Export screen with checkboxes for images, data, etc.

    • Use notebook as IDE for running sage instance - #7501.

    • Drag-and-drop file upload.

    • Don't list "Sage Users" when sharing.

    • Page through worksheet list, not all at once - tablesorter.

    • Toolbar with buttons to interrupt running code, save, attach files, etc.

    • Real-time concurrent editing - #7362.

  • Published worksheets:
    • Delete them.
    • RSS feeds.

    • Live cells, e.g, interacts - #6855.

    • Only to selected users or groups.
  • Notebook:

    • Tags / labels.

    • Manage logins:

      • View recent account activity. Add last login to user.py.

      • Invalidate other sessions' cookies.

    • Full-text search: SQLalchemy, Whoosh (codenode-devel).
