An Active Record transaction traced across one database connection, retained model state, remote side effects, false returns, non-local exits, nested transactions, savepoints, and PostgreSQL statement failures.
, a gem that brings the Durable Objects programming model (addressable objects, durable state, serialized turns) to ordinary Rails applications. It runs on the MySQL, PostgreSQL, or SQLite database the app already has. No Redis, no Cloudflare account, no separate actor service.
Turbo’s documentation is complete but unconnected: Drive, Frames and Streams sit side by side with nothing saying what links them or how to choose. This is the reference I wanted when I started, written by reading the source of Turbo 8.0.23 and turbo-rails 2.0.23 rather than the docs, because that is where the gaps are.
From Rails Dev to Shopify Partner: A Beginner’s Guide to Building Apps If you know Ruby on…
A conditional that keeps growing is a design problem, not a style problem. How to turn each branch into an object, one green step at a time.
In this article, Amanda goes through what a Ruby MCP server needs once it stops being a subprocess: Streamable HTTP instead of stdio, a choice between a standalone service and an endpoint inside an existing Rails app, statelessness so it survives more than one Puma worker, Host and Origin validation that a security advisory made mandatory, a shared token as the internal floor with OAuth as the answer beyond it, and read-only models and server_context deciding what any caller can actually reach.
, a Rails gem that records each request or job execution as one dense, high-cardinality telemetry event. It gives coding agents queryable production context without making them reconstruct what happened from scattered logs, spans, and metrics. Agents can retrieve only the relevant rows and fields for a route, account, build SHA, feature flag, or error, keeping the context compact.
An Active Record save traced from pending dirty state through validations, callbacks, persistence, and its transaction wrapper. It explains false returns with empty errors, validate: false, callback-chain inspection, successful no-op saves, and why a failed inner save can leave other work committed. RailsRevelry publishes one source-backed Rails mental model each week.
Active Record objects hold the database-derived state they loaded; they do not stay synchronized when another process changes the row. I built four small, reproducible experiments covering stale reads, lost updates, optimistic locking, and association-cache staleness, then looked at Rails’ abandoned Identity Map and what genuinely live objects would require.
Wiring an LLM into a Rails app takes a handful of lines. Understanding what it actually costs you (feature by feature, user by user) is harder.
Sentry and Honeybadger are great — until you don’t want another vendor, another bill, or exception data leaving your infrastructure.
I finally published the written version of my Rails World talk:https://greg.molnar.io/blog/the-state-of-security-in-rails-8/

I created HyperActiveForm to implement Form Objects into a Rails app. Easily extract form validations and logic into a handy and testable class.
Covert discrimination is often hard to spot because it happens as personal microdiscrimination against one person or few people only without them belonging to a common minority group. As such, the people discriminated against are not protected by any minority group anti-discrimination measures, and are often abused without the abuse being detectable by outsiders because the abusing discriminators treat outsiders without discrimination, so they become none the wiser about the microdiscrimination happening against the one individual or few that are discriminated against. That is why I wrote a guide to spot covert discrimination in the Ruby Community and beyond.https://andymaleh.blogspot.com/2024/12/how-to-spot-covert-discrimination-in.html

One slightly under-documented ingress for ActionMailbox is using Postfix relaying. It is easy to integrate into an existing Postfix mail server by just adding another virtual_alias_map and also supports Regexp matching of many different mails (so 1 mail per customer easy achievable). Goal is to POST the mail into our App-Server using a small CURL script without adding new dependencies to the MTA server.

The newest tty-link implements a brand-new API that supports Alacritty, Kitty, WezTerm, and many more modern terminals. It allows hyperlink detection configuration with a keyword or environment variable.
I have been seeing a lot of discussion comparing Elixir with Ruby for its concurrency features. The point these discussions miss is that Elixir runs on top of ErlangVM which had concurrency built-in as it was developed for running humungous-large-scale telecom systems. Whereas, Ruby was developed by Matz as a Software Language easy to understand and write. Ruby already had concurrency features through threads and fibers since its 1.9 version and Ruby 3 added parallelism features through ractors. This article covers all these 3 in detail and with a lot of code examples related to even AI and ML. Read it here - Understanding Ruby 3.3 Concurrency: A Comprehensive Guide.

How to scale databases using Postgres Logical Replication to optimize performance, manage read replicas and easily handle intensive loads.
Some Software Engineers mention “not being interested” as an excuse not to help someone with something that could benefit customers or the Software Engineering community at large (including the Ruby community) when the real reason is in fact covert discrimination against that person and lack of effort to treat them as an equal and equally respected member of their community. Know that Software Engineers have to abide by the Software Engineering Code of Ethics. And, it includes the statements: “Software engineers shall act consistently with the public interest” and “Software engineers shall be fair to and supportive of their colleagues”.

Hey, I’m a Rails developer with lots of interest in infrastructure. I’ve published a project that allows you to spawn much faster runners for Github Actions, self-hosted in your AWS account, and for much cheaper than official runners. Some users with heavy Rails codebases managed to save 80% of their cost, and most importantly greatly speed up their test suites.
Software Engineering activities are split between ones that provide direct value to customers in the short-term and ones that indirectly benefit customers in the long-term. It is important to have a good balance of both in order to ensure the long-term viability of Software Engineering work and continuously offer maximal value to customers. The best Software Engineers out there are those who have mastered the skill of balancing short-term direct-value activities with long-term indirect-value activities.
I’ve been cooking up a new way to build command-line apps with Rails that I call Terminalwire. Similar to Hotwire, Terminalwire doesn’t need an API because it streams STDIO (and a few other channels) over WebSockets. This means you can use Thor, or any other Ruby command-line parser, to build out a CLI on the server and updates are automatically deployed when you deploy your Rails server. This will lower the bar for developers who want to deploy a CLI app, like Github & Stripe, without having to manage an API.
I created some high-level Rails Generator cheat sheets to help create a unified list of the available actions, inflections, and variables that work within Rails generators. It doesn’t provide documentation, but it’s handy for remembering the name of the action or variable when it’s on the tip of your tongue.
Performance issues in the PostgreSQL layer usually start to manifest only when your app reaches a certain scale. In this blog post, I’ll discuss easy-to-miss database config tweaks and common problems that I’ve encountered in multiple Rails projects.

It’s amusing and affirming to me that system testing (in Rails) has been declared a failure. I could’ve told you that years ago! I’ve spent much of the past ten years working with test suites that are slow, brittle, and ultimately uninformative—almost always because they’re overly reliant on testing end-to-end.
Puts Debuggerer finally goes version 1.0.0, and it now has a very helpful new feature: printing the invoked class method as part of pd printouts. For those unfamiliar with Puts Debuggerer, the project was inspired by a blog post by Aaron Patterson titled “I am a puts debuggerer”, which jokingly borrows from the wording of the comedy movie Dumb and Dumberer, turning debugger to “debuggerer”. The Puts Debuggerer Ruby gem aimed at automating most of the suggestions in that blog post.https://andymaleh.blogspot.com/2024/05/puts-debuggerer-100-includes-invoked.html

Glimmer DSL for CSS 1.3.0 and 1.4.0 just shipped with support for CSS Media Queries and a CSS To Glimmer Converter!!! This gem is included in Glimmer DSL for Web to enable styling elements with CSS via a Ruby DSL. Glimmer is smart enough to have multi-DSL support, meaning it enables using a Ruby DSL for CSS and another Ruby DSL for HTML in the same file, and it’s all Ruby code in the end, so one language, but interpreted differently depending on the applicable domain to facilitate writing the simplest code possible for each domain. https://andymaleh.blogspot.com/2024/05/glimmer-dsl-for-css-media-queries-css.html

Janus is a read/write split proxy for MySQL/ActiveRecord 7.1+. It works by sending any read queries to a replica, and any write queries to the primary database server. If there’s been a write statement within the same thread we stick any future queries to the primary server unless the developer specifically chooses not to.
This is (for now) a modest step-by-step tutorial about creating a MacOS desktop application with Ruby.
Following last week’s beta, version 2.0.0 of re2 (Ruby bindings to Google’s RE2 “fast, safe, thread-friendly” regular expression library) is now available from RubyGems. Unlike version 1, it no longer requires the underlying RE2 library to be installed separately as it is now vendored with the gem and precompiled, native gems are available for Linux, Windows and macOS.
APIs allow us to communicate with third party software in order to use their services and data. In today’s software it’s almost impossible not needing to use one, one way or another. What if they are hostile?
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.
We’ve already posted on client side feature flags, how we added a free plan, and an awesome relay race to ship a new feature. I forgot to post here but will for future posts.

Distributed architectures have been growing in popularity for quite a while for some good reasons. The rise of cloud services making the deployments simpler, as well as the ever-growing complexity of the applications, resulted in a shift away from monolithic architecture for many technical ecosystems. Microservices have emerged as an alternative solution offering greater modularity, scalability, reliability, agility, and ease of collaboration between multiple teams. Nevertheless, these benefits don’t come for free. The price to pay could be significant due to many factors, and one of them is dealing with some challenges that don’t necessarily happen when working on a monolith. One of such challenges is establishing the best way of integration and communication between services.

In the past few months, I’ve added development containers to several Ruby on Rails (and other languages/frameworks) applications. I’ve learned a lot along the way, and wrote some off the cuff thoughts on how I approach dev containers, how I treat them differently from production containers, and where there’s still room for improvement. Hope you’ll check it out!
Ever wanted to modify an ENV variable, an instance or class variable (e.g. on Config) for the duration of a block or for all tests of a “describe” group? This pattern emerged repeatedly in my suites and as I don’t like to bloat my test/spec helper, about time for the lightweight and dependency-free minitest-substitute gem. Drop cumbersome before and after handling with one or more easy to read with "ENV['FOO']", "bar" or with "@run_at", on: Config { Time.now } declarations. Happy testing!

I wrote about how I approach Test Driven Development in a very very lightweight manner at https://fly.io/ruby-dispatch/organic-test-driven-development/ by keeping gem dependencies, source code, unit tests, and documentation in a single file. This helps me keep iterations tight and rapid early on in a project. Once I’m ready to distribute it as a gem I break it apart into the usual files you’d see in a project.
The Global VM Lock (GVL), is an implementation detail of the Ruby VM. At a high-level, it prevents code across multiple threads from running in parallel. The GVL can have a big impact on the performance and responsiveness of any application that uses more than a single thread to do its work. I’ve recently presented on this topic at RubyKaigi 2023; live interactive examples, the video, and slides are available at https://ivoanjo.me/blog/2023/07/23/understanding-the-ruby-global-vm-lock-by-observing-it/ .

This just out: minitest-flash reporter – dull as ditchwater yet useful IMO. It simply calls your personal minitest-flash executable (usually a shell script) to trigger whatever fancy red/green notification you like. Safe to use on team projects as nothing happens unless the executable is present. The README showcases my setup for macOS which flashes the menu bar twice in either red or green along with an optional sound effect (mutable in case your ears have better things to do).

Every self respecting Senior Software Engineer out there should build their own code editor, even if just as a toy app to later be discarded in favor of another code editor (though they might grow to prefer their own). And, if they are Rubyists, they should build their code editor in Ruby (whether using MRI Ruby, JRuby or Opal Ruby). If you think of yourself as a Ruby Senior Software Engineer, but cannot build your own code editor in Ruby, there are serious holes in your skillset!! Explore Glimmer libraries for many Ruby options to help you start the code editor building challenge and journey.

This is my journey with two leading web development frameworks: Rails and Elixir. Having invested years in Rails, I ventured into Elixir, captivated by its claims of high performance, resilience, and distributed systems. I admired Elixir and its Phoenix framework but encountered complexities when revisiting past code. On returning to Rails, I experienced greater intuitiveness and efficiency, especially with the innovative Hotwire design. Despite the unique advantages of Elixir, such as its Ecto library for complex queries, I felt more aligned and efficient with Rails. Ultimately, I decided to rewrite my Elixir-based project, Rauversion, in Rails, completing 90% in just two weeks, and I’ve had the opportunity to contrast the strengths and weaknesses of both ecosystems.
is it ordinal summer? i’ve written-up a step-by-step guide to define your own paint by number or letter image class - using the bixel (7x7px - 10 colors) and biixel (10x10px - 21 colors) specs / protocols as real-world examples. happy pixel (or bixel or biixel) pushing with ruby.

In Ruby, method names can be suffixed with !. These are often called “bang” methods. This is used to indicate that it is a dangerous counterpart of the non-bang version of the method.
Building apps over time, I found some work that needs to be done on every application: Authentication, Authorization, Mailers, etc. I started extracting this standard functionality into a Rails engine a few years ago. Later, tailwindscss, hotwire, stimulus, and phlex entered the picture, so I started the engine again with reusable UI patterns that take advantage of these tools. This is how Maquina was born. https://mariochavez.io/desarrollo/2023/08/08/maquina-the-engine-for-rails/
Hello, some years ago I published a red paper to introduce sruby - Small, Smart, Secure, Safe, Solid & Sound (S6) Ruby to the world with a runtime (and gem) called universum. Now fast-forward and middlemarch (a.k.a. Tom Lehman) introduced dumb contracts on ethscriptions with the production code written in a dialect of Ruby called “Rubidity”. Q: Why do you choose ruby for dump contracts? A: Because you can create a mini-language that’s very similar to Solidity and will be easier for Solidity devs to use. Hear. Hear.
When enforcing canonical URLs, sometimes I find myself wanting to perform a redirect while retaining most of the params. It’s tempting to use params.merge to build the redirect in this case, but this is risky from a security standpoint. In this article I’ll explain how to perform redirects like these safely in Rails 7. https://mattbrictson.com/blog/safe-rails-redirects
I’ve just launched pre-orders for https://railsnotesui.xyz , where I’m building a component library of ActionMailer email components. Rather than hard-coding HTML <tables>, you’ll be able to build emails with ViewComponents like Email::Button and Email::Footer.

https://github.com/railsjazz/chat_gpt_blocker is a bit funny project, assuming it was created by ChatGPT. Some websites should be ready to block access from the bot.
I wrote about what it’s like pairing with GPT-4 on a ruby Ruby at https://fly.io/ruby-dispatch/pairing-with-gpt-4/.

If you’re starting out, it can still give you pretty good results if you don’t ask it to build stuff for you. Overall, it’s more pleasant than using a search engine for help because you don’t have to wade through ads and SEO content that’s not helpful.

Bridgetown gets better with every release and along with rock solid static site features, the optional dynamic capabilities go well beyond a simple SSG. That said, your growing Bridgetown site might rely on external services and APIs at some point and managing their credentials with environment variables is tedious at best. Enter the Bridgetown Credentials plugin which implements the best parts of credentials from Rails: Commit encrypted credentials to the repo and decrypt them on the fly.
In the same way, words or the language (we speak) shape our thinking and our reality, programming language constructs or features shape how we define a problem and the solution that we code for that problem:
Hello, in the ongoing crypto winter programming series in ruby I added yet another gem, that is, abi2sol that ships with a command-line tool that lets you generate solidity (contract) source code from application binary interface (abi) definitions (in json).

Let’s start the new year with a hot take! I think Authentication Zero is a bad idea for security. I summed up here why I think that:
What’s ahead in 2023 in rubyland? I am not making it up my “good old friends” - Richard Schneeman (Schneems) and Brandon Weaver - that perma-banned “cancel cultured” for life my humble selffrom r/ruby & ruby-talk (see r/planetruby for some background)are now leading a conspiracy to “cancel culture” DDH from rails. Can it get any more absurd than that? What’s your take on the absurdity in the name of “wokeness” in rubyland in 2023. Whom do you want to “cancel culture”? Let’s conspire ;-). What if you are next? (Hint: If you are a random nobody like my humble self - nobody cares - they will tell you to “move on”).

Hello, to help out all ethereum & co gems in rubyland I have started a new abicoder gem that includes application binary interface (abi) encoder & decoder for easy (re)use with zero-dependencies on any 3rd party gems incl. any of my own ;-). The idea is to work together in 2023 on any missing functionality - I have already pinged / invited the eth.rb lead. Happy blockchaining with ruby. Happy New Year. Prosit 2023! PS: A little user survey - What’s your ethereum gem of choice? Does it support tuples (or tuple arrays) in (contract) function calls?
Ruby has a mechanism for handling errors and exceptions in a clean and organized manner, but using exceptions too frequently or improperly can negatively impact the performance of a Ruby application.

Developers can create some incredible applications using Ruby on Rails best gems. Using Ruby gems is a standard practice in developing web applications in Ruby on Rails. Using the gems listed here, along with other Ruby gems, it is possible to create a customized Rails app that fits the needs of any company, and allows for fast software development, to get fast time-to-market, and stay competitive. A Gem in the Ruby programming language is a software package where Ruby applications or libraries can be deployed in a uniform format. For Ruby on Rails gems, an interface is a command-line tool called a gem that can install and manage a library. A gem embeds the Ruby programming languages runtime loader, which helps to find and load installed gems from unified libraries folders. RubyGems is a package manager for Rails which includes a standard format for distributing Ruby programs and libraries (in the form of a self-contained framework known as gem), a tool to manage the installation of the gems, and a server for shipping them. Read: How to create a gem in Ruby on Rails?
When it comes to developing Web applications, there are literally dozens of frameworks available for almost any programming language, but two of the best known and trusted are Django in Python and Rails in Ruby. Ruby on Rails has the best examples for building web applications, showing its dominance over a vibrant web community, while the Ruby programming language is similar to a complete solution, where applications are found across the backend, the M.L., and the web. Python-based is ranked among the best programming languages, and is known to emphasise the clarity and readability of code, while Ruby on Rails is known for attributes like flexibility and freedom, as well as for its easy-to-understand syntax. Django is among the most popular Python-based frameworks among experts in the language. Read More on RoR vs Django

Hello, if anyone tries to request data from the ethereum (open) blockchain (service / database) with ruby sooner or later you might want to understand the magic and put together a to-the-metal “raw” json-rpc request with a recursive length prefix (RLP) encoded-data package. Good news - there’s a rlp gem with 1+ millions downloads; bad news - last update in 2016 and the (ruby) source code is officially archived / read-only). Anyways, using the “best of the both worlds”, that is, the “inline” rlp encoder/decoder from the eth gem and the rlp gem itself I put together a new rlp-lite gem. It’s the early days ;-). You are welcome to join in and try the new kid on the block. What are your (eth) options (in ruby) that you use? Please tell / share / discuss.

Hello, if anyone is crypto (blockchain) programming in ruby - sooner or later you will need a Keccak and/or SHA3 (crypto) hash function / digest class - some popular options are gems with c-extensions - so with great surprise I found this week “less popular” hidden (crypto) gems in “plain-old” ruby and zero-dependencies on c-extensions. The two options are Keccak256 by Evan Taylor and SHA3 (“Pure Ruby”) originally by Christian Neukirchen et al and “gemified” by Shannon Skipper. Thanks! Anyways, I have started to use the “hidden (crypto) gems” in the ethlite gem that lets you call (blockchain) contract (services) via JSON-RPC and all works out great so far. What are your (crypto hash or eth) options (in ruby)? Please tell / share / discuss.

Service objects and/or after_commit callbacks are ubiquitous in most real-world Rails applications. Whether it’s a good idea or not (ActiveRecord callbacks - I’m looking at you) is a different story, but one thing that is notoriously overlooked in the application design is reliability. And yes, the service objects are equally bad as after_commit callbacks in that regard.
ActiveWorkflow 0.9.16 has been released. This is a minor release that adds the ability to wipe out workflow state (useful during workflow development) by removing all messages, log records and agent memory with a single button (with confirmation, just in case).

Hello, In the ongoing learn pixel art programming with ruby series I put together a new artfactory gem that let’s you generate pixel art via text-to-image prompts - no A.I. training or models needed / required ;-). The “magic” works via all-in-one image spritesheets (and meta datasets in .csv). To get you started I “right-clicked & saved” about a dozen “on-blockchain” artwork layers for easy “off-blockchain” (re)use. Happy pixel pushing and profile pict(ure) pixel art generation with ruby.
