Finding Relationships Between Ruby’s Top 100 Packages and Their Dependencies — RubyGems recently began rolling out a new security policy for protecting the most heavily used gems, but what about the dependencies of those gems? Kevin got to work using the (very useful) RubyGems data dumps and found that ‘24 of the 112 big gems rely on small gems’ but really the journey is more interesting than the outcome here.

DHH and Basecamp: "Why We're Leaving The Cloud" — Rails’ creator David Heinemeier Hansson is also CTO at Basecamp, 37signals or whatever it’s called this week, and as a prettttty significant Ruby and Rails shop, it’s interesting to see his take on the cloud vs self hosting. In other news, DHH has also discovered that LinkedIn is actually pretty good.

✉️  The Short Ruby Newsletter — A newsletter that's not by us! But don’t be fooled, it’s actually waaaay longer than Ruby Weekly but does a good job of digging up Ruby related tips, opinion and discussion from Twitter in particular. A good way to keep up with tips and chatter while we stick to the boring stuff ;-)

  • The dry-rb family of libraries has adopted Zeitwerk for code (auto)loading.

  • gemdex.org is a new and experimental way to search for Ruby gems by placing weights on different priorities you might have.

  • A few weeks ago, Dave Kimura began doing weekly 'This Week in Rails' video news roundups on YouTube. ▶️ Here's this week's video. (4 minutes.)

re2: Ruby bindings to Google's RE2 Regex Library — RE2 bills itself as “a fast, safe, thread-friendly alternative to backtracking regular expression engines” and this project brings it into the Ruby world. Note that re2’s regex syntax differs from what you might be used to. v1.5.0 adds a new ‘set’ feature for matching against a collection of patterns simultaneously.

pg_enquo: A Way to Securely Query Against Encrypted DataEnquo (standing for “ENcrypted QUery Operations”) is an admittedly niche (for now) approach as it also requires client support (currently only in Rust and Ruby – yes, there's a Rails integration) but it’s interesting to see experiments in this area given increasing concern and legislation around data privacy and security.

FastPage: Faster Pagination for ActiveRecord with Deferred Joins — Given it’s from the PlanetScale managed MySQL folks, you won’t be surprised this is for MySQL users only. It uses a MySQL specific optimization to improve offset/limit queries.


premailer-rails-revived: For Inlining CSS into HTML Emailspremailer is the established gem for this task with premailer-rails integrating it with Rails. After some questions around its maintenance, however, this fork appeared to add Rails 7 support. The original author of premailer-rails has since promised fresh development so you’ll need to do your research before picking a solution in the interim. GitHub repo.

A New Tech Demo of the DragonRuby Game Toolkit — For some reason, the DragonRuby Game Toolkit hasn’t quite caught my imagination yet, but it’s fun to see what other people are achieving with it, and this demo is pretty neat for only a few hundred lines of Ruby. (Video example included – yes, did you know you can host videos on GitHub gists now?)

An Experiment in Building a Roguelike in Ruby — Very early days for this passion project by a developer who is keen for feedback – it’s more a maze game so far, but he explains his work quite well in the README.
