Print redundant indexes in a Rails app.
# Unnecessary indexes slows down writes and consumes additional storage and memory.
# Just paste this snippet in your Rails console (bundle exec rails c).
# And it will print all redundant indexes that are already covered by another index on the table:
# Table `pages`: index `site_idx` (site_id) already covered by `site_slug_idx` (site_id,slug)
# Table `optins`: index `list_idx` (list_id) already covered by `list_active_idx` (list_id,active)
ActiveRecord::Base.connection.tables.map do |table|
indexes = ActiveRecord::Base.connection.indexes(table).select(&:valid).reject(&:where)

Big list of http static server one-liners

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

A gallery of interesting Jupyter Notebooks(https://github.com/jupyter/jupyter/wiki/A-gallery-of-interesting-Jupyter-Notebooks)

This page is a curated collection of Jupyter/IPython notebooks that are notable for some reason. Feel free to add new content here, but please try to only include links to notebooks that include interesting visual or technical content; this should not simply be a dump of a Google search on every ipynb file out there.

Important contribution instructions: If you add new content, please ensure that for any notebook you link to, the link is to the rendered version using nbviewer, rather than the raw file. Simply paste the notebook URL in the nbviewer box and copy the resulting URL of the rendered version. This will make it much easier for visitors to be able to immediately access the new content.

Note that Matt Davis has conveniently written a set of bookmarklets and extensions to make it a one-click affair to load a Notebook URL into your browser of choice, directly opening into nbviewer.
