Notes

Project by Nicholas Currault. The source code is available on GitHub.

To conserve processor and network resources, this app should only update four times per day.

Updates

On 2022-11-30, a Heroku issue that took the app down for a few days was resolved.

On 2020-10-01, a "behind the scenes" update made the app much cheaper to host, but the first new request of each day will take a while to load. If you get a blank page, try again in a few minutes.

On 2017-03-17, an update removed consideration for Computerphile, as suggested on H.I. #79: From Russia with Love

Between 2015-05-31 and 2015-06-24, I updated to Google's new API (v3). This caused a few errors with the site, but it should be fixed now.

On 2015-01-06, an update added Brady's new channel, Objectivity.

On 2014-10-11, an update removed the consideration for Grey's second channel, CGPGrey2.
