I recently had a client that wanted a primer on the quickbooks api for oauth. Below find a short video tutorial of how to copy, configure and run a django api that uses login with quickbooks. I also go over the oauth flow between intuits servers and the django api endpoints.
Recently I struggled with a Django form. The requirement was to specify a placeholder html data attribute. This task is very standard but the search terms involved made it tricky to find a solution online. I provide it here to help others.

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.

There are lots of materials on how to train neural networks but not as many showing how to deploy them to power real services. In this post I’ll share a minimal example of how I train tensorflow models and deploy them on Sagemaker. I’ll cover items that I found intimidating so hopefully they become less intimidating to you.
An app that’s tailored exclusively to English-speaking users won’t compete in the overall market. You could make 10x the revenue you currently make by adding global localization to your app. You limit your own chances of reaching a larger customer base if you don’t localize your business for users who speak different languages and live in different regions.
Running a full bitcoin node on osx is a good way to familiarize yourself with blockchain administration. You can explore the ledger locally and you don’t suffer any of the risks Simple Payment Verification nodes suffer from. You can “Be your own Bank” or so they say. If you have ~300 GB of free disk space you should try it out.
