Building a Site Around Thousands of Diary Entries from Samuel Pepys

In this episode of Running in Production, Phil Gyford goes over building a community around 9+ years of diary entries from Samuel Pepys. The site was built with Django. It gets about 150k+ page views a month and has been up and running since 2002. It’s currently hosted on Heroku.

Phil talks about being in the sweet spot in terms of engagement while not being under high load, rewriting the platform with Django as a monolith, how Heroku helps him get it all up and running without needing to bother with servers and much more. The site is open source.

Support the Show

This episode does not have a sponsor and this podcast is a labor of love. If you want to support the show, the best way to do it is to purchase one of my courses or suggest one to a friend.

  • Dive into Docker is a video course that takes you from not knowing what Docker is to being able to confidently use Docker and Docker Compose for your own apps. Long gone are the days of "but it works on my machine!". A bunch of follow along labs are included.
  • Build a SAAS App with Flask is a video course where we build a real world SAAS app that accepts payments, has a custom admin, includes high test coverage and goes over how to implement and apply 50+ common web app features. There's over 20+ hours of video.
