We deploy Python/Django apps to a wide variety of hosting providers at Caktus. Our django-project-template includes a Salt configuration to set up an Ubuntu virtual machine on just about any hosting provider, from scratch. We've also modified this a number of times for local hosting requirements when our customer required the application we built to be hosted on hardware they control. In the past, we also built our own tool for creating and managing EC2 instances automatically via the Amazon Web Services (AWS) APIs. In March, my colleague Dan Poirier wrote an excellent post about deploying Django applications to Elastic Beanstalk demonstrating how we’ve used that service.

Here at Caktus, we’ve been fortunate to work on some incredible projects with our clients. For example, we built the world’s first SMS voter registration app for Libya, developed a digital archiving system for the world’s largest on-demand video provider, and created a survey tool with auto-scaling architecture to help the University of Chicago track school reform.

I attended the TriAgile conference in Raleigh, NC on March 30th, 2017 and wanted to share some takeaways from a couple of the talks I saw. Overall, the conference was a nice opportunity to network with some local Agilists and hear about their work and experiences. It was well organized, and I was pleasantly surprised by the size of the Agile community in the Triangle!

Subtests are the best

Testing our code is important. Because developers write bugs, it’s valuable to catch and correct them before the code gets to production so our apps work as they should. Specifically, we want tests that are DRY (Don’t Repeat Yourself), thorough, and readable. Though there are many ways to try to accomplish these goals, subtests make each of them easier. If you’re not using subtests in your test classes, you probably should be.

Caktus attended PyCon 2017 in Portland from May 18-21. It was the first PyCon for some, while others were PyCon veterans. All of us were looking forward to the opportunity to hear some great talks and make or renew connections in the Python community.

When considering a website upgrade, many business stakeholders probably think about the frontend, i.e., how the website looks or the features users interact with. Perhaps less often considered is the importance of upgrading the backend; that is, the databases, applications, and servers powering all the behind-the-scenes activity. Infrastructure support and upgrades are necessary but often performed as a separate project from any improvements to design or user experience, rather than as part of a holistic update project.
