The Alternative Implementation Problem
In this post, I want to talk about a dynamic that I’ve seen play itself over and over again in the software world. In fact, I would venture a guess that this kind of situation probably happens in the hardware world as well, but I’ll speak about software systems since this is where my experience lies. This discussion is going to touch a bit on human psychology, and outline a common trap so that you
Ractorを用いたproperty based testingの並列実行についてRubyKaigi 2024で発表しました - valid,invalid
表題の通りRactorを用いたproperty based testingの並列実行についてRubyKaigi 2024で発表してきました。かつスピーカーとしての参加は初めてで、いろいろ稀有な体験ができて総合的にはめちゃくちゃ楽しかった。 発表内容について "Unlocking Potential of Property Based Testing with Ractor"という題で、property based testing（以下PBT）において発生する小さくて大量のタスクをRactorで並列実行させるというアイデアと仮説検証の結果を報告しました。 日本語のテキストで概要を知りたい方はTechouse社の記事をご参照ください。登壇者の自分が発信したどのテキストよりも丁寧にわかりやすくまとめてくださってます。この場を借りて感謝いたします！ developers.techouse.com

Ruby typing 2024: RBS, Steep, RBS Collections, subjective feelings
Ruby typing 2024: RBS, Steep, RBS Collections, subjective feelings I was writing a new Ruby gem recently, and being a strong proponent of a type checking step, I wanted to do right by the ecosystem so that anyone using it would get the full benefit of type checking against my gem’s API in their own projects, so I dug into the current state of the art to find out how that’d be done. I used Sorbet f
Autotuner: How to Speed Up Your Rails App
This article was adapted from my Rails World talk “Rails and the Ruby Garbage Collector: How to Speed Up Your Rails App”. Ruby’s garbage collector is designed to be adaptable, scaling from short Ruby scripts to running apps that serve millions of requests per second. While it’s designed to be adaptable, it may not work optimally for every use case. For this reason, Ruby’s garbage collector support

The answer is in your heap: debugging a big memory increase in Ruby on Rails
I recently participated in an interesting series of debugging sessions tracking down the source of a large increase in memory when upgrading a Rails application. We ultimately tracked down the cause using John Hawthorn’s Sheap heap analyzer and successfully submitted a patch to Rails. I thought it was interesting enough to write up because maybe the general approach to debugging memory issues woul

GitHub - rage-rb/rage: Fast web framework compatible with Rails.
Inspired by Deno and built on top of Iodine, this is a Ruby web framework that is based on the following design principles: Rails compatible API - Rails' API is clean, straightforward, and simply makes sense. It was one of the reasons why Rails was so successful in the past. High performance - some think performance is not a major metric for a framework, but it's not true. Poor performance is a ri

RailsアプリのCI高速化
参加しているプロジェクトで、RailsアプリのCIの高速化を行った。 まだ進行中の部分も幾つかあるが、結果から言うと、元々8分前後だったテストが3分半程度に短縮された。行った作業を幾つかの観点に分け、どのように高速化を行ったか、どの程度高速化されたか等を記述する。 プロセス数とマシン性能の調整 元々は2コア1プロセス4マシンで8分程度掛かっていたが、8コア8プロセス1マシンに変更することで5分程度に短縮された。 このプロジェクトではCIにGitHub Actionsを利用している。GitHub Actionsではデフォルトで2コアのマシンが利用されるが、Large runnerを利用して8コアに変更した。費用は変わらない。 また同時に、8プロセスで並列実行するためにparallel_testsを導入した。このプロジェクトではMySQLとElasticsearchを利用しており、またファイル
