Podcasts for Data Science & Stuff

I asked the Twittersphere for data science (& tangentially-related) podcasts recommendations, and got a much bigger response than I expected with some really superb recommendations, so I created a gist with the suggestions I received. They're arranged alphabetically by name below, along with relevant Twitter accounts, links, and names of the hosts (if I could find them).

Shoot me a tweet @bennyjtang if you have more suggestions to add to this list!

This is a quick tutorial explaining how to get a static website hosted on Heroku.

Why do this?

Heroku hosts apps on the internet, not static websites. To get it to run your static portfolio, personal blog, etc., you need to trick Heroku into thinking your website is a PHP app. This 6-step tutorial will teach you how.
