Naming Things Is Hard (opens on the source site)
Choosing good names for objects and methods in code is one of the toughest things to do as a software engineer. It comes with the great and invisible reward of simplicity – second only to having less code in the first place, having code that’s easy to reason with makes extending it and debugging it in […]

Crafting Code: Building a Ruby Pattern Generator for a Crochet Circle (opens on the source site)
In my time as a developer, I have noticed that one of the most common ways my coworkers spend time coding outside of work is by developing little code snippets or apps that solve problems in their everyday lives. From household budgeting, to managing workouts on rowing machines, to generating a Taco Bell order, these projects allow devs to explore different coding styles and learn new technologies. For a long time, most of my side projects have been for the sole purpose of learning a new technology. When I wanted to start building mobile apps with React Native, I wrote a small to-do app that,…

Creating a Custom Mobile Integration for a Board Game Using Ruby on Rails (opens on the source site)
Picture this: you find a charming old board game at a garage sale, bring it home, gather some friends—and snap. The 50-year-old plastic components break instantly. You search the web for help to replace this fun and unique game mechanic but there’s nothing to be found. So naturally, you roll up your sleeves and build your own mobile version. No one else does this? Just me? Well, in case you ever find yourself in a similar boat, I figured I would walk you through what I did when building my own mobile integration to the 1973 Parker Brothers classic Billionare. As I said, right when I went to…

Why Ruby is the Best Language for Advent of Code (opens on the source site)
It's the most wonderful time of the year - Christmas Advent of Code time! Advent of Code is an Advent Calendar style series of programming puzzles put out each year, starting on December 1st leading up to Christmas. The puzzles are super festive and ramp up in difficulty over the course of the month. Programmers of every level can participate, and in researching some of the more difficult problems you'll probably learn something cool! It's a great way to finish out the year. I've been taking part in Advent of Code since 2019 (I've never completed a full year - and that's ok! You can…

How To Rev Up Your Rails Development with MCP (opens on the source site)
Shipping new features on legacy Rails applications requires deep codebase context. The rails-mcp-server gem closes the gap between AI agents and your Rails projects, enabling more relevant code analysis and context aware refactoring suggestions. Whether you're dealing with tech debt in a brownfield application or building new greenfield features, this tool can help you move faster with confidence. The Model Context Protocol (MCP) is a way to allow LLM models to interact with development environments and external tools. The rails-mcp-server gem is a Ruby implementation that enables LLMs to…

Some Thoughts About Claude Code (opens on the source site)
Claude code is a powerful AI toolset that runs right in your terminal. While providing a lot of impressive utility, it also suffers from the issues that arise from similar AI toolings with the addition of an expensive pricing model. Context is Important To me, the main selling point for Claude Code is its ability to read through your entire codebase; a big shortcoming of many AI workflows is the model only partially understanding an issue due to it not having enough of the project's context and convention to be effective. Claude Code has the ability to access all of the files in the directory…

Layers vs Silos, a tale of 2 microservice architectures (opens on the source site)
When it comes to the communication between microservices, there are 2 possible extremes:All-sync: whenever a service needs data from another service, it fetches it via a synchronous API call (REST, gRPC, GraphQL). Service calls service calls service… which tends to evolve into layers of APIs, where each layer has dependencies on the next.All-async: no sync calls between services, all communication is event-driven or in the form of data replication. This tends to form silos: independent services that are fed all the data they need by an async mechanism and can function independently of any…

Our microservice stack (opens on the source site)
This is an introduction to how we’ve implemented microservices at a mid-size scale-up called Jobteaser, with a mix of Go and Ruby service chassis, gRPC APIs and data replication via Kafka.Foundation: The service chassisBack in early 2019, when Jobteaser decided to get serious about breaking up its decade-old Rails monolith into microservices, we assembled a Foundation team that started working on an in-house service chassis.It was soberly coined service and came in two flavours: the rb-service framework in Ruby and the go-service framework in Go. Four years later, they still form the…

Exercism Review (opens on the source site)
Exercism.io is a fantastic site and tool that provides a wealth of daily code exercises. If you want to learn to be better in a language, it's a great resource to do exercises and receive feedback. Origin Exercism.io was introduced to me by Franklin Webber of gSchool and JumpStart Labs fame. He and his colleagues use it as a part of their instruction, and it's a great, free tool available to the public. Languages There is a fun array of language-learning possibilities inside Exercism. It currently includes a varying number of exercises across these languages: clojure elixir haskell javascript…
