1. Our Pair Programming Ethos

    Pair programming is more than just a way to build software, it’s the way we build teams. Great software is made by great teams. At Test Double, we value pair programming, and over the years we’ve refined our technique.

  2. Speed up your Rails app with upsert_all

    Amid the rise of object-relational mapping (ORM) tools like ActiveRecord in the mid-aughts, many developers learned in a hurry what “N+1” queries were and word quickly spread on how to avoid the crippling performance problems they can cause.

  3. A Few of My Favorite Things

    I love watching the masters at work. Trying to keep up as Rick Harding plows through code in vim, riding along as Sam Jones conducts multiple sessions in tmux, or marveling at Suz Hinton’s setup for live coding inspires me to up my own game and become a more productive developer.

  4. Introducing Ecto Resource

    CRUDy contexts can jam up the works in an Elixir/Phoenix application Contexts allow for a separation of concerns between data and business logic. Often times, the first thing we do is add many basic CRUD functions to our contexts which essentially delegate to Ecto.

  5. Remote, but not alone

    You already know what this post is and what prompted me to write it. But if you know me, you also know I wouldn’t be sharing this unless I felt there were things worth saying about remote work that weren’t being said elsewhere.

  6. Improving Dev Experience with Overmind

    Web apps are born with a healthy amount of naivety. There aren’t many expectations of what the apps should do so they have the freedom to do… well, anything. This is great for the early stages of development, but as these apps grow and take on more responsibilites a flexible, little app can quickly become hard to manage.

  7. The Missing Fundamental

    Music composition and production is a large part of my life outside of software development, so much so that I often find myself thinking of ways to draw parallels between the two.

  8. Necessary & Sufficient

    One reason testing is such a hard skill for developers to master is that the purpose of a test suite is rarely self-evident. Production code, meanwhile, rarely needs its motivation spelled out; after all, what is the purpose of an app that sells chocolate-dipped bananas but to… sell chocolate-dipped bananas?

  9. The Slippery Slope of Docker Dev Environments

    Recently, I built up a local development environment that uses Docker for some critical integration test paths. As I put the finishing touches on this work, I realized there were some far-reaching implications that I had not taken into consideration before I started down this road, namely:

  10. Conditional Rendering Tactics for React Components

    A common situation when writing React components is needing to render a particular component only under certain conditions. There are many ways to accomplish this, but the route you take often has nuanced implications or differing utility based on the current state of the code/component/system.
