Snapshot testing with insta is a great fit for developing GraphQL APIs in Ruby.

Taking a brief look back at the work of the farm in 2025.

Several weeks ago, I took an afternoon to walk the pastures at St.

I recently added a custom profiler to GraphQL-Ruby.

This is a rapid-fire look back and what I was up to farm-wise in 2024.

I got into milk because I love cheese.

2023 was a big year for Lake Road Farm.

I’ve been wondering, besides keeping warm and being decent, does it matter what we wear?

Boy, it’s hard to believe 2021 is already over.

At my job, we’re working on revamping the global ID system we use for GraphQL.

I recently re-skimmed Lesslie Newbigin’s The Gospel in a Pluralist Society.

About a year ago, we migrated an old rate limiter to Redis.

GraphQL-Ruby 1.12 ships with a new GraphQL::Dataloader feature for batch-loading data.

2020 turned out to be a great year for books.

I thought I’d try to remember what I read last year.

Some notes on a refactor implemented with a Cop.

Did you know that calling return in one Ruby method could affect the flow of another method?

Yesterday I excitedly recommended to a friend that he try making some yogurt at home.

GraphQL-Ruby 1.9.0 introduces a new runtime called GraphQL::Execution::Interpreter.

I just finished reading E.F.

As part of my work on improving GraphQL-Ruby’s runtime performance, I’ve been reading Essentials of Programming Languages.

This May, I had the opportunity to attend Balkan Ruby and present on my work with graphql-ruby.

Ruby has a few different kinds of variables, and Ripper expresses them with a few different nodes.

GraphQL 1.8.0 was designed and built largely as a part of my work at GitHub.

GraphQL-Ruby 1.8.0 will have a new class-based API for defining your schema.

This fall, several people presented their work on Ruby type checkers.

For Planning Center free week, I cooked up react-rails 2.0 🎊.

You can tell Ruby on Rails to respond to changes in certain files during development.

GraphQL 1.5.0 includes a new way to define a schema: from a GraphQL definition.

One way to keep an eye on your GraphQL schema is to check the definition into source control.

Soon, graphql-ruby 1.5.0 will be released.

It’s possible to get IO operations running in parallel with the graphql gem.

graphql-ruby is almost two years old!

In general, raising exceptions for control flow makes code hard to understand.

State machines are applied to a wide variety of programming problems.

I read that Hash#key?

css_modules provides an approach to styling UI components in a local-first way.

I just got back from RubyConf Colombia.

Specialising Dynamic Techniques for Implementing the Ruby Programming Language (“Specializing Ruby”) is approachable and enjoyable (despite being a PhD thesis 😝).

I like using Sprockets, but sometimes it’s hard to find a file to include in the asset pipeline.

When reviewing issues for react-rails, I see many questions about how to gather JavaScript dependencies with Sprockets.

Elixir modules offer some valuable insight into designing Ruby classes.

Although Relay made GraphQL famous, GraphQL was in use at Facebook for years before Relay took the scene.

This question is too hard.

The Crystal programming language combines Ruby-like syntax with a really powerful compiler.

The Christian practice of communion is a reminder of why Jesus is important and how his life affects us.

A GraphQL system works differently from a “traditional” RESTful JSON API.

I had leftover whey after making yogurt, so I made ginger ale.

This weekend I tried making yogurt.

Pat Shaughnessy’s “Using a Ruby Class to Write Functional Code” gives an example of bringing functional programming principles into object-oriented design.
