Have you ever looked up at the sky and wondered if the International Space Station was flying by at that moment? In this live coding adventure we will cover the basics of scheduling tasks with RQ in Django by building a web app that sends you text message notifications whenever the ISS passes by your location. Technologies covered will be the ISS Open Notify API, Twilio SMS, RQ, and RQ Scheduler.
The international space station (ISS) is an orbital outpost circling high above our heads. Given a location on Earth (latitude, longitude) the ISS Open Notify API will compute the next
n number of times that the ISS will be overhead. I will cover step by step how to build a web application that notifies users via text message when the ISS is passing over them.
This talk is live coded and will involve me switching between writing code in my text editor (vim), terminal windows and web browser. It is based off of a tutorial post I wrote for the Twilio blog.
In the Django app built during this talk, Redis will be used to store subscriber information such as a user's phone number and geolocation. RQ and RQ Scheduler will be used to execute a function that sends a text message notification using the Twilio API at a given datetime.
At the end of my talk, I will send a text message containing the code I wrote, and a walkthrough on how to get it running to all of the audience members who interacted with the live-coded web application from my session.
