Distributed tracing allows to observe requests as they propagate through distributed systems, especially those built using a microservices architecture. In a distributed environment, tracing also helps you understand relationships and interactions between microservices. Distributed tracing gives an insight into how a particular microservice is performing and how that service affects other microservices.

Here we show how to select all records that occur in an hour. This is useful for cases where you are running an async task at some interval smaller than a day. My first attempts at doing this type of filtering involved providing a start and end datetime. But there is a way to do it more simply by leveraging some database functions.
Here we share a small django management command that sends an email. This command is useful because it will use the same email credentials the rest of your django api is using to send emails. So you can use this as a sanity check to see if your settings are correct.

Like many software projects there is never enough time nor enough engineers so the project was not tested for Android. When they finally got around to running the app on Android it was too painful.

Async tasks are an intermediate backend engineering problem. Most public facing apis need to return an answer under 1 second for a good user experience. However many real world tasks require more than 1 second to complete or need to be scheduled to repeat. The solution is usually to create a task that can run asynchronously. In Django one way to accomplish this is by writing a management command.
