Running in Production

In this episode of Running in Production, Michael Lynch goes over building a hardware device that lets you remote control your server without installing any software. It’s been available since mid-2020.

Michael talks about how it works, using Ansible to provision a Raspberry Pi, Using Flask with SocketIO, rendering 30 frames per second at 1080p with under 200ms latency, using web components, selling his devices on Shopify, hiring quality freelance developers and more.

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.
