I co-hosted episode 488 of The Ruby on Rails Podcast. Brittany and I talked with Allison McMillan and Chelsea Kaufman about all the plans for RubyConf 2023.
All the thanks to Brittany Martin for asking me to join. I didn’t have podcast hosting on my career bingo card.
A Rinha de Backend que aconteceu em Agosto de 2023 foi muito divertida. Eu só fiquei sabendo quando acabou, mas não quer dizer que não pude me divertir. Hoje quero resumir tudo que eu fiz nos 16 dias seguintes do evento, detalhes sobre os projetos dos participantes, a controvérsia do Ranking de Linguagens, quais os truques por trás dos vencedores, e como você também poderia ser um vencedor!
Finalmente vou demonstrar o que significa "ser promíscuo" com linguagens de programação. Vamos entender porque como de fato ler um ranking. E como podemos fazer TODO MUNDO alcançar o primeiro lugar do Rust!
If you are using the i18n gem with Ruby 3.0 or are planning to upgrade Ruby to 3.0 while using the i18n gem, this blog post will cover a gotcha that can be tricky to understand.
Suppose you are using the i18n gem in an application and the code has some logic depending on Ruby’s frozen? method, then you would see totally different behavior in Ruby 2.7 and in Ruby 3.0.
Take a look at this code snippet when run in Ruby 2.7
# Ruby 2.7
a = I18n.t("user.title")
a.frozen?
=> false
b = a.clone
b.frozen?
=> false
Here the translated result stored in variable a is not frozen. And when we clone
the object a, the cloned object is also not frozen.
Now let’s take a look at the same…
Introducing changes to complex systemsAt Gusto, there has been a big push to think about modularization at every step of the development process. Whether it’s driving features in the monolith through the use of packwerk, or adopting yarn workspaces in our front-end code, modularization has been a key initiative to help scale feature development at Gusto.
The decision to adopt GraphQL as the communication protocol between the frontend and backend was made in order to harness its inherent advantages. GraphQL offers a significant degree of freedom and flexibility, enabling developers to craft requests tailored to specific client use cases, ultimately enhancing the efficiency and precision of…
Special co-host Kevin Murphy joined Brittany this week to interview Allison McMillan and Chelsea Kaufman, co-chairs of the upcoming Rubyconf 2023 happening in San Diego. The quartet discussed lessons learned from Railsconf 2023, the approach to thinking about and planning this year's Rubyconf and what is new and different at the event.

This is an updated version of the post I wrote about MRKS in the past.
Sidekiq allows Ruby developers to maintain fast and responsive web applications by moving time-consuming tasks into the background.
With multithreading at its core, Sidekiq can process many jobs at once. This makes Sidekiq an important part of Ruby or Rails applications that handle heavy loads or perform tasks like sending emails or processing files. Without background processing, long-running tasks would block your application's main thread, resulting in slow response times and a poor user experience.
In this post, we'll focus on effectively utilizing Sidekiq to manage and process background jobs.
Let's get started!
In essence, Sidekiq is a full-featured background…
Welcome to the RubyGems monthly update! As part of our efforts at Ruby Central, we publish a recap of the work that we’ve done the previous month. Read on to find out what updates were made to RubyGems and RubyGems.org in August.
This month in RubyGems, we released 3.4.18, 3.4.19 and Bundler 2.4.18, 2.4.19.
In RubyGems, we improved the documentation performance by speeding up the build process when updating RubyGems - #6864. We added a poller to fetch WebAuthn OTPs - #6774, added a file option to the Ruby method in the Gemfile - #6876 and removed some side effects when unmarshalling old Gem::Specifications- #6825.
Some other improvements that landed into our repo this…
We’ve likely heard this advice throughout our lives: listen more than you talk. In a world of social media, influencers, and seemingly constant opinions and arguing, listening gets put on the back burner, and the focus is all about talk.
That can be especially true for recruitment, a career where conversing with people is often viewed as the central theme. It’s a bit of a stereotype, but recruiters can be notorious at tech and software engineering events for being the loudest people in the room—pushing conversations on others without noticing how the people they’re speaking with are uninterested in what they’re trying to say. Ever pushing, needing to talk, talk, talk. This sales-y…
Joël describes an old-school object orientation exercise that involves circling nouns in a business problem description. The purpose is determining which nouns could become entities or objects in a system. Stephanie shares she's working from the Hudson Valley in New York as a trial run for potentially relocating there. She enjoys the rail trails for biking and contrasts it with urban biking in Chicago.
The conversation between Joël and Stephanie revolves around mentorship, both one-on-one and within a group setting. They introduce a new initiative at thoughbot where team members pair up with principal developers for weekly sessions, emphasizing sharing perspectives and experiences.
…Ruby Central is a non-profit organization dedicated to support and advocacy of the worldwide Ruby community.
We produce the annual RubyConf and RailsConf conferences, support community growth, and provide vital infrastructure for the Ruby programming language by maintaining the bundler and rubygems packaging services in addition to other open source projects.
The board of directors for Ruby Central act as representatives to the community and work to ensure smooth operations today and smart strategy for tomorrow. We meet once a month and all take turns working as co-chairs of the conferences.
To support our conferences and programs, we're looking to fill multiple board seats! We'd love to have…
One of the primary goals of the Rails Foundation is to improve the Rails documentation for both new and existing users. We have a lot of ideas about how to achieve this, and we are now ready to start tackling this with the help of an experienced UX designer and a technical writer (or two) with a strong Rails background.
These two roles will have a lot of opportunity for cross-collaboration to find (and close) gaps in the current content. Both roles will also work closely with members of the Rails Core and Issues team as well as volunteers from the Rails community to understand the needs and pain points of Rails users.
Here are some of the projects that you could be working on:
In Rails 7.1, an enhancement has been introduced toActiveRecord::Batchesmethods, related to models with composite primary keys. This update allowsdevelopers to specify ascending or descending order for each key within acomposite primary key.
In Rails versions prior to 7.1, when batch processing records with a compositeprimary key, like id_1 and id_2, developers could use the :asc or :descargument to control the sorting order. However, there was a limitation in howthis sorting worked. When you specified the sorting order using :asc or:desc, it affected both id_1 and id_2 simultaneously. In other words, ifyou requested ascending order, both id_1 and id_2 would be sorted…
There’s a style of reactionary meme that takes a photo of like, empty store-shelves or a trash-strewn street, and applies the image macro “This is what Communism looks like”.

Sinatra is a lightweight web application framework written in Ruby. It provides a simple and easy-to-use syntax for building web applications. The framework focuses on being minimalistic, allowing developers to quickly create web applications without having to deal with a lot of the boilerplate code and relatively rigid way of doing things that accompany larger and more popular frameworks like Rails.
In this article, we'll use the Sinatra framework to build a simple URL-shortening app where a user can input a long URL and generate a short URL that redirects to the original URL when clicked. The app will also have a feature for keeping track of how many times a shortened URL is clicked.
pry-byebug gem. Since then, I've switched to the debug gem for all my Ruby debugging needs, and hence re-publishing the updated post.
Reading the source code is a great way to understand how a feature works in Rails. However, stepping through the specific Rails method you're interested in is even better. You can inspect the local variables, follow the conditional path, and learn exactly what's happening behind the scenes.
This post shows how you can debug and step-through the Rails codebase for a better understanding of the framework.

Hello! I was talking to a friend about how git works today, and we got onto the
topic – where does git store your files? We know that it’s in your .git
directory, but where exactly in there are all the versions of your old files?
For example, this blog is in a git repository, and it contains a file called
content/post/2019-06-28-brag-doc.markdown. Where is that in my .git folder?
And where are the old versions of that file? Let’s investigate by writing some
very short Python programs.
.git/objects
Every previous version of every file in your repository is in .git/objects.
For example, for this blog, .git/objects contains 2700 files.

Monkey-patching in short is modifying external code, whose source we don’t directly control, to fit our specific purpose in the project. When modernising framework stack in “legacy” projects this is often a necessity when an upgrade of a dependency is not yet possible or would involve moving too many blocks at once.
It’s a short-term solution to move things forward. The reward we get from monkey-patching is instant. The code is changed without asking for anyone’s permission and without much extra work that a dependency fork would involve.
But it comes with a hefty price of being very brittle. We absolutely cannot expect that…

When deploying a Rails application to production, its rare to question the idea of running a Postgres or MySQL database to persist data and Redis for caching, background job processing, and WebSockets, but what if it could all be done without running these services?
“No part is the best part”, right? Here’s the thing, Redis and Postgres run as separate processes that need to be monitored. Usually these processes are running on a separate server that’s accessed over a network connection, which can also break. You’ll either have to deal with that complexity yourself or pay to have it managed with services like Upstash Redis.
What if we could run everything on one server and not have to…
We are used to checking the deprecation warnings displayed by Rails or warnings from different gems, but Ruby itself can also display warnings to help us find code that can be problematic.
In this article we will explore how to use them, how to analyze them, and some examples of interesting warnings that can be really helpful during upgrades.
The ruby command accepts the -w and -W arguments that will enable the highest level of verbosity for warnings.
The -W argument also accepts a verbosity level value:
-W0 means warnings are completely disabled by setting $VERBOSE = nil

Caching is an effective way to speed up the performance of Rails applications. However, the costs of an in-memory cache database could become significant for larger-scale projects.

I’ll also discuss a more advanced technique of using in-memory cache for extreme performance bottlenecks.

Refactoring is a technique of transforming the code without making changes in its functionality. Why people do that?

The Exchangeable Image File Format (EXIF) is a standard that specifies formats for images and sounds. It stores technical details through metadata, data that describes other data, such as the camera make and model and the date and time the image was taken.
Initially, EXIF was used for two image formats, JPEG and TIFF. But today, other file formats such as PNG, WEBP, or HEIC also support EXIF for metadata.
This article will focus on the JPEG format. In the first part, we will explore its structure before seeing how to read and update associated metadata through Javascript in a browser environment.

Hi! This is Vipul bringing you the latest from this week’s changes in the Rails codebase.
Infer primary_key: :id on associations with composite primary key models
Prior to this change, you’d need to do the following to set up associations for composite primary key models:

self.primary_key = [:shop_id, :id]
has_many :order_agreements, primary_key: :id
end
class OrderAgreement
belongs_to :order, primary_key: :id
end
After this change, the primary_key option no longer needs to be specified:

Good code has a lot to do with how readable it is. As developers, we more often read code than write it. As my Perl teacher told us many times: the flexibility of Perl's syntax was its best and worst trait at the same time. Ruby's syntax was influenced partly by Perl and is also quite flexible.
Whatever language you pick, set some guidelines to avoid overusing a language's flexibility. Style guides for Ruby abound on the web, and it's not difficult to pick a style nowadays. But there is not much point in having copious debates on style and whether a proposed change follows a guide. Style enforcement is best left to a tool.
Such tools are called linters and static code analyzers. The de…

STEPHANIE: Hello and welcome to another episode of The Bike Shed, a weekly podcast from…
When we work on Rails upgrades, most of the time we have to solve issues after updating the gems. These problems can go from simple and straightforward to really complex and hard to debug. Here we will discuss different skills and techniques that we use to complete the upgrade.

I wanted to see how fast I could make a GraphQL parser without writing any C extensions. I think I did pretty well, but I’ve learned some tricks for speeding up parsers and I want to share them.
Today we’re going to specifically look at the lexing part of parsing.
Lexing is just breaking down an input string in to a series of tokens.
It’s the parser’s job to interpret those tokens.
My favorite tool for tokenizing documents in Ruby is StringScanner.
Today we’re going to look at a few tricks for speeding up StringScanner based lexers.
We’ll start with a very simple GraphQL lexer and apply a few tricks to speed it…

In my last post, I rewrote a little Rails app with Roda and Turbo Streams. In this post I’ll show how I solved the app’s last and biggest problem: slow API calls. So slow that the user had to wait several seconds between pressing the “Next article” button, and actually seeing a new article.
The app is called Wiki Stumble. Here’s the live site and the GitHub repo. The app shows summaries of Wikipedia articles personalized to the user’s likes and dislikes.
Due to Wikipedia APIs not having…
Recently one of the RailsEventStore users posted an issue that one wanted to use RES on a Postgres database with PostGIS extension. Migration generator used to setup tables for events and streams was failing with UnsupportedAdapter error.
In RailsEventStore we supported to date PostgreSQL, MySQL2 and SQLite adapters representing given database engines. But if you want to make use of mentioned PostGIS extension, you need install additional activerecord-postgis-adapter and set adapter: postgis in database.yml. Our code relied on value returned by:
ActiveRecord::Base.connection.adapter_name.downcase
=> "postgis"
I thought — Ok, that’s an easy fix, PostGIS…
We recently launched a new open-source page. While this blog post gives a good overview of why we chose to highlight particular content, we also faced some interesting technical challenges while building it.
A lot of what occurs in the open-source world happens on GitHub, and thoughtbot is no exception. All our repositories are hosted there, so this was a natural place to start. We also wanted to highlight our team’s contributions to other open source projects in the community.
GitHub has a GraphQL API that allows us to query for all the information we need with a single request. We used the graphql-client gem to query the GitHub API. This…
This post originally started as an answer to this question on Reddit: When to use lambda or proc vs. regular functions. As with all my writing goes, it got so large that I had to convert it to a blog post.
A higher order function is a function that
It's a very important and powerful concept in functional programming, and Ruby has a first-class support for higher-order functions, via its delicious flavors like blocks, procs, and lambdas.
In this article I’m going to take a look at software quality as a way to differentiate between junior, mid-level, and senior software engineers, through the lens of failure demand, purely so that I can introduce a new concept that I thought up on a walk today, which I’m calling negative failure demand.
The Rails SaaS boilerplate Business Class goes 1.1. Here’s what’s new.
The release of Business Class had an unfortunate timing since Paddle just recently announced all new offering called Paddle Billing. But it didn’t stop me. I worked hard last month and rewrote all functionality of Paddle Classic to Billing for this version of Business Class. The whole integration is also based on latest version of Pay and comes with an even larger set of tests.
Business Class is therefore now the very first Rails template supporting Paddle Billing.
Business Class originally shipped with a revamped Rails scaffold generator with automatic team scoping, but the new…

In this episode, Jason, Chris, and Andrew start us off with a conversation about burger toppings preferences, discussing whether certain ingredients should be included in “the works” and sharing tips to prevent burger slippage. The discussion transitions to programming topics, exploring the challenges of working with multiline environment variables and the intricacies of Bash scripting. The guy’s dive into the benefits of building UI components using frameworks like Tailwind CSS and Alpine.js, emphasizing the importance of well-organized and specialized components for better code management. The conversation also touches on the desire for more pre-built component libraries in the…
