This is how to set up the One True Development Environment for Python.

Haha, just kidding, there is no such thing. Here's one way to do it that works for me, and an attempt to explain the benefits of doing it this way.

We’ve published summaries of our most popular blog posts before (see Top 19 of 2019 and Top 18 of 2018), but this time, we’re taking it a step further. We’re sharing the 20 most popular posts in 2020, regardless of the year the post was originally published. And some of these have been around a while! Based on total pageviews, here are the blogs that rose to the top of the popularity list, from most viewed to least viewed.

I keep up with what's happening in my field by following a number of blogs and an occasional email list. I don't read everything posted in all of these, but by scanning the topics in a feed reader, I can keep up with what's going on, without wasting a lot of time.

Stateless authentication with JSON Web Tokens  —  safely!

As developers who build REST APIs, we are quite familiar with JSON Web Token (JWT) based authentication. The typical pattern is this:

React is a library that helps developers approach user interface (UI) development with the single-responsibility principle in mind, while building reusable, encapsulated components. But when it comes to styling, there is a heated debate in the React community. There are a few schools of thought:

Part one of a two-part series.

A REST API is a wonderful way to expose application data to a wide variety of clients. Anything that can speak HTTP can communicate with a REST API, and these days that means an exciting variety of devices. From plain old web browsers to mobile devices to a whole array of IoT applications  —  there are a lot of good reasons to use a REST API. And if you’ve ever built one, you’re familiar with the predominant means of restricting endpoints to authenticated users  —  JSON Web Token (JWT) based authentication.

Above: Caktus uses several mobile devices for accessibility testing. For a more realistic experience, it’s important to test on devices, and not just with simulators.

One of the great patterns to come out of React 16.8 is composable hooks. Using React's built-in hooks such as useState and useEffect, we can encapsulate and modularize bits of functionality — almost the same way we create reusable components. In this article we're going to throw together a quick hook that registers an event listener on a keypress and performs an action. Nothing fancy, but it's a nice abstraction that makes it a lot easier to add some nice power-user features to your app.

When running services in a container, changes to files can be discarded at any time, but the Celery beat default scheduler keeps its state in a file.

For the Review, Appraisal, and Triage of Mail (RATOM) project, funded by the Andrew W. Mellon Foundation, we were tasked with deploying to a Microsoft Azure environment. More details about the project are in our first blog post in this Learn With Us blog series. Caktus has experience with Amazon Web Services (AWS) and Google Cloud, but we hadn't had the opportunity to use Azure yet, so we looked forward to the opportunity to use that environment and document our experience. The entire deployment process is available on GitHub as a reference under the StateArchivesOfNorthCarolina/ratom-deploy repository.
