💎 New GemStuffer Campaign: Socket detected a RubyGems registry abuse campaign stuffing scraped UK council portal pages into junk gems. PoC worm, scraper, or spam? Low downloads, repeated publishing, and 155 artifacts tracked so far. New Research → socket.dev/blog/gemstuf...

Finally got around to collecting together Ruby resources into one place. Some really cool stuff in here.

Rubyists! I am reviving Ruby Inside after 12 years of hiatus. I have too many Ruby things I want to blog about :-) So far I've got the archive up and running at rubyinside.com/archives/ - it's a bit of a Ruby time capsule..

Welcome to Hanakai! The new home for Hanami, Dry, and Rom. hanakai.org/blog/2026/05...

I have been trying mise (from @jdx.dev) and rbenv recently, the winner is clear: $ time ruby -e0 mise: 51ms rbenv: 152ms 100ms overhead is way too much (due to shims). Additionally: * rbenv breaks `which` which causes tricky problems. * mise can install precompiled Rubies (much faster)

Where are you in the relationship with Ruby? 1. First date (learning) 2. Going steady (1-3y) 3. Old couple (4-10y) 4. Married with kids (10y+) Reply with your number. What kept you here? — #Rubycon2026 #RubyLang

When context compaction kicked in automatically I always miss the decisions, the failed approaches, the reasoning behind every choice? So I built a session handoff system to fix this in superpowers-ruby

When working on a new product after adding Stripe, the first thing that I like to add is this page. It could be because I've missed it in so many SaaS products :) and maybe because I live in the EU where it is important to have a proper invoice for accounting write-offs.

I think codex needs to put a bit more love into hooks. The docs show very few hooks and I think it will help a lot with plugins ecosystem.

An update about @shortrubynews I have not sent a new edition for almost 3 weeks. Let me explain why and what is next.

Here's a post that is equal parts "spatial queries in SQLite are neat" and "here are the weird corners you will absolutely run into." If you're using Rails with SQLite and want spatial queries without switching to PostGIS, this will save you some time. www.hansschnedlitz.com/writing/2026...

If you haven't tried @avohq.io I think you should. I never skip this step when I write what gems or features I need to build or have installed before any launch.

OmbuLabs/FastRuby released a Rails upgrade skill for Claude Code last week. That made me think superpowers-ruby should have one too. It now does.

I was switching between three planning skills mid-session because each one solved a different problem. office-hours asked the right forcing questions. ce:plan-beta structured implementation well. plan-ceo-review kept scope tight. So I built one that sequences them properly

When Claude wants to see just a little bit what else are you working one and decides to go out of the current folder :)

superpowers-ruby v5.0.6 is out. Compound skills, compound-refresh, and a Ruby idiom fix that matters more than it looks.

I'm so incredibly excited just to go to Tropical on Rails! ✨ Being able to share everything I've learned about Docker and Devcontainers over years of use across numerous projects just makes it so much better!

The Short Ruby Newsletter will not be sent this week, as I have too many other things to handle. I will try to make sure next week's edition includes what happened last week. Meanwhile, do upgrade your Rails version: see rubyonrails.org/2026/3/23/R...

Added a new skill, "ruby-commit-message," to help create better commit messages. It focuses on writing commit bodies that help junior Ruby developers understand changes during debugging. This helps LLM explain the change better without fluff words.

While upgrading RuboCop in a project, I noticed three new style cops in v1.85.0. I almost skipped them. At first I thought they were just syntax sugar but I think they are nice additions and they make Ruby code match better with the language idioms.

I am organizing the second Sibiu GenAI Practitioners Circle on May 25. Topic: Agentic Engineering - Where Does the Engineering Go? This is an active working session. We will share thoughts, discuss in small groups, and build together a mental model about how to work with AI

I made a fork of superpowers and change it to work with Ruby and Ruby on Rails: github.com/lucianghind... Integrated a bunch of existing skills - I linked them in the Readme if you want to use them directly and added my own for Ruby and Testing.

Now that Campfire, Writebook and Fizzy can be installed with Once is anyone working to have a kind of unique login for all 3 of them? I wish that I could add someone in a single place and then they could have access to all 3 without creating a new account on each one fo them.

Not sure what the exact conditions are. It says they’re triggered by .rb files, but I didn’t get it every time. I think if you set ENABLE_LSP_TOOL in your env section for Claude Code, then when it works with a Ruby file you might get this prompt:

Yesterday I released cctop v0.11.0 with a redesign and 4 color schemes! If you want a lightweight macos app to help you monitor Claude Code/opencode sessions with keyboard navigation, give cctop a try: github.com/st0012/cctop

One of the features for which I love Ruby is that it has syntax features that let me express clearly what the intention of my code is. - `unless` instead of `if not` - `until` instead of `while not` - `loop do` instead of `while true` #Ruby #Coding

RuboCop 1.85.0 ships with a built-in MCP server. You can now give Claude Code or OpenCode direct access to RuboCop as a structured tool. Here is how to set it up.

OpenCode automatically installs Ruby LSP when working with Ruby files. It shows "ruby-lsp" in the UI, but that is does not run ruby-lsp gem. It actually runs rubocop lsp. I did a bit of digging about why this is the case.

This is great news but ruby-lsp’s indexer has many known limitation, including performance issues. So we’ve been building a new indexer to replace it. And it will come with a default MCP server tailored specifically for LLM agents.

A previous version of an image that I shared about configuring Claude Code has a mistake with the name of the repository.

Ruby LSP is now an official Claude Code plugin. With it, Claude queries the language server directly - same as your editor does. Without it, Claude reads the file and tries to extract the structure manually.

If you know someone from Anthropic, this is a good time to whisper to them to add Ruby LSP to their official plugins: github.com/anthropics/...

Rack provides Rack::Deflater (to compress response), but not Rack::Inflater (to decompress requests). I just wrote a simple one.

Current state of how I used AI as an engineer for the past four weeks 🙌 Thread 👇

JRuby currently has no official ActiveRecord support for Rails 8, but one of our users discovered that a build from master works right now! It will need some cleaning up, but we'll be caught up with Rails compatibility very soon. Rails 8 plus JRuby 10.1 will be a game changer.

PureJPEG is a pure Ruby JPEG encoder and decoder. While it works as expected, it has a bunch of features to get retro/distorted JPEGs, which is what I was really going for: github.com/peterc/pure_... (Examples shown in the README!)

There’s an issue with @beehiiv, the provider we use for @shortrubycom. If you visit the newsletter, you may see “CNAME Cross-User Banned” or “404 Not Found” I’ve submitted a ticket and I’m waiting to hear when it will be fixed.

Now that Obsidian has a headless client, you know what works really well with it? github.com/tobi/qmd — it’s a much better search than what Obsidian provides, and you can integrate it with any LLM. Check the repo’s “skills” section.

Due to some personal things I have to take care of this weekend, there will not be a Short Ruby Newsletter sent on Monday. I may be able to send it on Tuesday, but we’ll see how the week looks. There’s already a big archive of previous editions at newsletter.shortruby.com/archive

We've been planning something new… On Thursday evening after Day 1 of the conference, we're going to be hosting an optional roundtable discussion, to talk about the changes happening in our industry, and how we as Rubyists are working through it. www.youtube.com/watch?v=vP3e...
