IndexedDB Full Text Search (Proof of Concept)

This demonstrates the implementation of full text search for documents in Indexed DB.

  • Word-breaking and stemming is used to create a list of terms for each document.
  • Document records are annotated with the list of terms when added to the database.
  • A multi-entry index on the list of terms is populated.
  • A query is similarly processed into a list of terms.
  • A join over the terms is implemented using multiple cursors on the index.

The necessity of annotating records with the word list to populate the index is a limitation of the current Indexed DB API. A feature request to support custom

Rickshaw Graph is a drop in replacement for Dashing's graph

Graphing Widget

The graphing widget shows graphs using the Rickshaw graphing library. The names of data fields should be (vaguely) familiar if you've used Rickshaw before.

It's recommended that you replace the /assets/javascripts/rickshaw.min.js from your dashboard with the latest from here.

Supported HTML data fields

git pre-commit hook for stripping output from IPython notebooks
#!/usr/bin/env python
"""strip outputs from an IPython Notebook
Opens a notebook, strips its output, and writes the outputless version to the original file.
Useful mainly as a git filter or pre-commit hook for users who don't want to track output in VCS.
This does mostly the same thing as the `Clear All Output` command in the notebook UI.
