David Heinemeier Hansson·41wAll-in on Omarchy at 37signals
37signals is transitioning their Ops and Ruby programming teams to Omarchy, their own Arch-derived Linux distribution, over the next three years. DHH argues that Linux provides superior control over your computing destiny compared to closed-source operating systems like macOS or Windows. While acknowledging some efficiency gaps, particularly in battery life with Framework laptops, he views this as a worthwhile trade-off similar to the sacrifices made during Mac's pre-Apple Silicon era. The move represents an exciting adventure for the company, with Omarchy already becoming DHH's favorite computing environment.

RUBYLAND·1yGit Rebase Squash
Squashing commits with Git can degrade the readability and searchability of your history, making tools like git bisect and git revert difficult to use. However, if commits are kept atomic, git rebase fixup becomes a superior and faster option. This post provides detailed instructions on how to squash commits properly, either via interactive rebase or using git commit --squash, ensuring a clean git history without losing valuable information.
RUBYLAND·51wRailway Pattern
The Railway Pattern enables fault-tolerant function composition by chaining operations that can either succeed or fail gracefully. Using Ruby gems like Dry Monads and Pipeable, developers can build robust pipelines where each step produces either a Success or Failure result, allowing errors to bubble up without breaking the entire flow. The pattern is demonstrated through building an API client that handles HTTP requests, JSON parsing, validation, and data modeling as a single composable pipeline, making code more resilient to network issues and data problems.
Ruby·22wRedesign our Site Identity

David Heinemeier Hansson·25wSix billion reasons to cheer for Shopify
Shopify processed $6.2 billion in sales on Black Friday 2025, a 25% increase from the previous year, handling 31 million API requests per minute and 53 million database reads per minute. The company, led by founder and programmer Tobi Lütke, continues to drive significant contributions to the Ruby and Rails ecosystems, employing nearly half of Rails core contributors and funding major improvements like YJIT and Ractors. This success demonstrates the scalability potential of Ruby on Rails at massive scale.
RUBYLAND·41wUndervalued: The Most Useful Design Pattern
Explores using value objects, data objects, and factory methods to decouple software components and improve testability. Demonstrates refactoring a tightly coupled XML feed generator by separating concerns through domain boundaries, transforming ActiveRecord models into simple data structures that isolate business logic from external APIs and database dependencies.
Simple Thread·27wI Love You, Redis, But I’m Leaving You for SolidQueue
Rails 8 introduces SolidQueue, SolidCache, and SolidCable as PostgreSQL-based replacements for Redis in the default stack. SolidQueue leverages PostgreSQL's FOR UPDATE SKIP LOCKED feature to handle job queuing without lock contention, eliminating the operational complexity of maintaining Redis infrastructure. The article provides a complete migration guide from Sidekiq to SolidQueue, including setup instructions, recurring job configuration, and Mission Control monitoring. While Redis remains necessary for high-throughput applications processing thousands of jobs per second, SolidQueue handles 200-300 jobs/second and is sufficient for most Rails applications, as demonstrated by 37signals processing 20 million jobs daily on PostgreSQL.
Ruby Flow·29wYou Don’t Need Types in Ruby
Ruby's dynamic nature and duck typing philosophy make static type systems like Sorbet and RBS counterproductive. These tools introduce runtime overhead, code noise, and maintenance complexity while contradicting Ruby's core design principles of message passing and flexibility. Instead of forcing type annotations, developers should embrace duck typing, use YARD for documentation, write comprehensive tests, and employ linters like RuboCop for code quality. The push for static typing in Ruby reflects a broader cultural problem of adopting tools for their own sake rather than understanding the language's strengths.

Ruby Flow·34wSupermail mailto links
Supermail is a new Ruby gem that simplifies email handling in Rails applications through a cleaner abstraction. The gem enables developers to generate pre-populated mailto links by instantiating email objects, making it easy to create support workflows. The example demonstrates creating a support email for failed checkout sessions that includes the Stripe session ID, allowing users to contact support with pre-filled context directly from their email client.
Tenderlove Making·21wCan Bundler Be as Fast as uv?
Bundler can achieve performance comparable to uv without rewriting in Rust by addressing architectural bottlenecks. Key improvements include decoupling gem downloading from installation to enable parallel downloads, implementing a global cache with hardlinks, and optimizing version comparison using integer encoding. The main challenges are backwards compatibility and navigating legacy codebases, not fundamental technical limitations. Most performance gains come from what the tool doesn't do rather than the implementation language, with opportunities for parallelizing IO-bound operations and eliminating unnecessary sequential dependencies during installation.
