The Art of Forking: Unlocking Scalability in Ruby — Karafka (a Ruby processing framework for Apache Kafka) requires concurrency and parallelism, which can present challenges in Ruby. The explanations here of how Karafka uses Ruby’s constructs is informative and shows that you don’t necessarily need to use another language to address issues of concurrency.

How Does Sidekiq Work? — Sidekiq is the most heavily used background job system in the Ruby space, and this post digs into how it works, its architecture, and what’s going on under the hood. Curiously, the post was written by Dan Svetlov but Mike considered it so good he bought the rights to republish it!

JRuby Prism: A New Parser for a New Era — In last week’s issue we mentioned JRuby's latest release and its use of the Prism parser. Here are the consequences: faster performance, reduced warmup, and a brighter JRuby future.

Running Rails on AWS Elastic Beanstalk — I hadn’t heard about Elastic Beanstalk in a Ruby context for years, but it was one of the first automated ways to spin up a webapp in the cloud directly from a repo. If you're on AWS, it still works well, and Josh goes through every step here.

Linear Regression using Dataframes in Ruby — How to use a basic tool of data science in Ruby, largely through the use of Polars Ruby and its DataFrame type.

How to Debug Issues with Turbo Morphing — The excitement around page morphing with Turbo likely has many a Rails developer adding it to their apps.. which then break. Read this if you need help figuring out why or just want to prepare before you introduce the concept.

MiniGL: A Minimal Game Library on Top of Gosu — We’ve linked to this a few times over the years, but it continues to improve. Super Bombinhas is the best known game built with it, but this new Tic Tac Toe-inspired platformer is worth a look too.

☀️ Astronoby v0.1: Work with Astronomical Data and Events — It’s very early days for this library, but it can, at least, calculate the Sun’s location in the sky based upon a particular observation point and time. Seems like a project worth getting involved with if you’re in this.. space? GitHub repo.

Hypershield: Shield Sensitive Data in Postgres and MySQL — Looking to hide sensitive data to help comply with GDPR, say? Hypershield creates ‘shielded’ views that can hide sensitive tables and columns.

Playing Sounds in Rails with the Audio API — Akshay picked up on how 37signals’ Campfire lets users play sounds in its chat interface, which involves a little more integration with Rails than you might think.

Finding Postgres Rows Too Large for BTree Indexes — From the “it may never happen to you” department, here’s an approach to find data that exceeds the allowed index size, which you could run into during a migration, as here.

Pagy 7.0: The Popular Pagination Gem — It’s been around for years, it claims to be the best pagination gem, and it’s still getting updates, so what’s not to like? v7 adds JSON:API support and rounds out its ARIA compliance. – GitHub repo.

A Decent VS Code Setup for Ruby and Rails Development — “Setting up VS Code for Ruby on Rails development can be tricky, so I wrote this article to help. In it, I share different VS Code extensions for things like autocomplete, linting, formatting and more.” Harrison also shares his own Ruby on Rails extension pack that brings together all his suggestions in one install.

WebMock: Stub and Set Expectations on HTTP Requests for Testing — Supports lots of HTTP libraries like Net::HTTP, Excon, the http gem, and Curb::Easy.

SearchCop 1.3: Search Engine-Like Fulltext Query Support for Active Record — Adds support for an easy to use search interface on top of AR models. It’s smarter than you might imagine and can handle using operators to query against columns – it’s not just for text. Support for Postgres’s hstore and jsonb columns has also just been added.

▶  Discussing YJIT with Maxime Chevalier-Boisvert — A 23-minute podcast episode with veritable Ruby VM and JIT compilation expert, Dr. Maxime Chevalier. She explains the whole concept of JIT from scratch in an accessible way, making this a great on-ramp to understanding what YJIT does, if you’ve ignored it all so far. (There’s a third party transcript that’s easy to read, too, if you prefer.)

Using Serial Ports with Ruby — Feeling that his UART gem wasn’t receiving enough, um, tender love, Aaron penned this article to show just how easy it is to work with serial ports and Ruby, particularly to interact with his.. Geiger counter?

JRuby 9.4.6.0 Released: The JVM-Based Ruby Implementation — The latest Ruby 3.1-targeting version of the longstanding JVM-based implementation adds support for the Prism Ruby parser (as introduced in CRuby 3.3), improves Ruby 3.1 compatibility, updates a variety of dependencies, and pattern matching is now supported by JRuby’s JIT compiler.

Need for Speed: Using RuboCop with Prism — Prism (formerly YARP) is a Ruby parser that wants to be the only Ruby parser in town (notably, TruffleRuby is now using Prism.) The creator of RuboCop shares that the migration to Prism has begun there too, and he anticipates solid speed gains.

Changing the IRB Autocomplete Colors with Reline::Face — The release of autocomplete for IRB was marred, for some, by not looking too hot with their terminal's color scheme (leading some folks to tweak their color settings). But now there's a way to change the styling to something you prefer by adding a few lines to .irbrc instead.

Ruby Koans in the Browser — We’re seeing more and more Ruby in the browser with WebAssembly (including in last week’s issue) and now someone has browser-ified the popular Ruby Koans exercises (note: this took a good 15-20 seconds to load in my browser).

How to Generate Random Numbers in Ruby — Just rand(x) right? That’s one way, but this post goes into so many more options. A good primer/reminder.

Hotwire Modals in Rails with Stimulus and Turbo Frames — We’re enjoying the excitement in the blogosphere on creating useful UI elements with Stimulus and Turbo.
