LLM agents are taking over so have decided to split my personal computing from work related (ie for privacy, data security etc) Just received my little work machine, a Ryzen 9950X with 64GB RAM, should speed up the test suite runs at least!

Remember, always run your coding agents inside containers github.com/anthropics/c...

Here's my Claude Code plugin for writing RBS for Ruby (also inline), which includes skills, agents and commands . https://github.com/stevegeek/claude-ruby-plugins Also includes a simple 'type tracer' that agents can use to help explore method return types at runtime.

Next gem to get a v1 will be https://github.com/stevegeek/typed_operation Its a 'command pattern' (aka callable/service object/???) gem, operations can be partially applied, curried and have typed parameters. Auth via action_policy if desired Now adding last things: chaining and instrumentation

Got bombed with random bot requests for .js files on a Rails app. The Ruby processes pegged at 100% CPU. Think it was cause Rails was raising and logging large number of ActionController::InvalidCrossOriginRequest exceptions. Time to add that missing `rescue_from`

Finally releasing 1.0.0 of my `encoded_id` gems (started 7 yrs ago in a client app) Use it to turn IDs into obfuscated reversible & human friendly strings. https://github.com/stevegeek/encoded_id (docs also have comparison to other similar gems to help you decide what to use)

Been finding optimising sqids-ruby and hashids.rb interesting. Wonder if I should turn the experience into a talk proposal for a conference... ie we live code through finding hotspots in some gem, try optimisations and consider why result performs better or not, and trade offs vs readability etc ? 🤷

Updating `awfy` (my Ruby benchmarking tool) so that you can run a benchmark suite repeatedly across a commit range and then compare results

This looks great, def going to try

Herb v0.8 is here! 🚀 The biggest release yet, packed with new language bindings, Linter Autofix support, Linter Fix-on-Save, a new `.herb.yml` config file, formatter improvements, Tailwind Class Sorting integration, and a ton of performance, tooling and LSP improvements! 🌿

Straight away Herb found 7 erb files with missing closing tags in the HTML and approx 130 linting errors such as missing alt tags, pointless use of `-%>`, anchor tags without an `href` etc. And parses all 555 erb files in 3-4 seconds. Really cool!

Today: removing `erb_lint` and my IDE tw CSS class sorting plugin... and adding `Herb` ❤️

Also coming in Herb v0.8.0, the long awaited Tailwind CSS class sorting feature in the Herb Formatter! 🌿 Here is a demo of that working in @zed.dev using the new `.herb.yml` configuration file! 😍

I was recently thinking about adding benchmarking across multiple Ruby versions with my `awfy` tool, and this looks perfect for managing that!

TIL `Symbol#name` returns a frozen string representation of a Symbol while `Symbol#to_s` returns a mutable String, resulting in a significant performance difference. For some reason I assumed they were the same.

If you are looking to use your voice more over typing for work (e.g. for RSI reasons), I highly recommend superwhisper.com ... seems to work very well with technical terms.

Got my #Rubycon Rimini ticket

Tickets for #Rubycon are finally available, grab yours before it's too late! ti.to/rubycon/ruby...

In the upcoming Herb v0.8.0 release, the Herb Linter will support a new `--fix` option to autocorrect offenses. This isn’t dependent on the Herb Formatter and uses the `printer` architecture, so the Linter can fix only the offenses without touching anything else in the document!

@marcoroth.dev sorry if missing the obvious, but is there any Herb powered tool yet that organises tailwind classes into a deterministic order? Checked rubygems and herb site but didn’t spot it

Is gem.coop basically a deployment of the rubygems gem? Or a fork of it?

Rubycon 2026, a new Italy based Ruby conference, will be held in Rimini on the 8th of May next year! Should be good, who wants to come?

Wow this is crazy… big thanks to the RubyGems team. You are very much appreciated by the community

Experimenting with using LM Studio + local model and custom MCP servers essentially wrapping around AppleScript , to automate chores on my computer, eg arrange files, tag notes, or provide a more natural language interface for apps such as Things

Yes, it is slow and steady progress, but we are genuinely building an amazing community of people and suite of tools for Ruby web developers. You should come hang out with us at discord.gg/fEMYkKQA

Back from the break. So much seems to have happened in 2 months its crazy. Prob should start with whatever was announced at RailsWorld.

At Rails World 2025, I introduced ReActionView, an initiative to explore what's possible in the Rails view layer for 2025 and beyond. As part of this, I announced Herb::Engine, an ActionView-compatible ERB engine built on top of the HTML-aware Herb Parser. #RailsWorld2025

I won IOCCC 2024! Here's a 2.5 KB rigid body simulator written in C. It can simulate the Tippe Top, a top that flips while spinning. www.youtube.com/watch?v=stPH...

Claude Code: "The tests are quite complex and need significant refactoring. Since we're running short on time, let me focus on the most critical" ... running short on time?

Oh no, very sad news

The new Phlex beta (2.4.0.beta2) now has a significantly improved compiler and now uses source maps to map exceptions back to the original source location. github.com/yippee-fun/p...

Once again Elixir is doing great, admiration wise https://survey.stackoverflow.co/2025/technology - Interesting on Ruby that its pretty low on the "Learning to Code" category now

I sometimes find using import maps in Rails confusing. If you are trying to use the highlight.js library, this was helpful:

Great stuff by @marcoroth.dev on Herb. Looking forward to our first peek at ReactionView

Been using dictation quite a lot in the past, especially Dragon, but after support for it dropped, I moved to macOS built-in dictation. However now using superwhisper and its amazing. Highly recommend if you use dictation on mac superwhisper.com

Started adding ‘context/‘ directories to my various gems to support github.com/ioquatix/age... . Good initiative along with agent.md to try get all this coding agent context stuff to be less messy

Picked up a few stars on github.com/stevegeek/de... , thanks @marcoroth.dev & Hotwire Weekly :) Got a big update coming soon which should take the component collection to a early "beta" state.

Im creating an open source UI library for Rails (using Phlex, my gem Vident & daisyUI/Tailwind). It's rough but I'm using it to build something so fixing/refactoring as I go. If your interested, keep an eye on github.com/stevegeek/de... & the previews are here yoe4v.hatchboxapp.com/lookbook

Marco is an absolute “machine for good” in the Open Source Ruby community. Can’t wait to try this out.

Call Screening sounds very useful. Glassy UIs, seems very not

Let's make it official. Instrumental Components has launched 🚀 Designing Rails apps with Tailwind, Stimulus, Turbo, & Stripe has never been easier. I sweat all the details so you (or your LLM) can ship! instrumental.dev

Piqué sur le Mammouth

Bought early access to @briancasel.com's instrumental.dev the other day, and since have started building 3 new apps with it. I like Instrumentals approach of using generators to install functionality. You pick/choose what you need, as you need it, rather than starting with a kitchen sink on Rails.

Lots of great new stuff coming to Ruby, RBS, Y/ZJIT etc. Big thanks to all the contributors and maintainers

A brand-new, pure-C RBS parser has been merged 🚀 It has no Ruby runtime dependency, so it can be embedded in Sorbet, JRuby & other tools. It’s the result of months of work by Shopify’s Ruby DX team: Alexander Momchilov, Alexandre Terrasa & me 😁 Details in github.com/ruby/rbs/pul...

This gem looks amazing github.com/gurgeous/tab... , def going to use it with awfy

I jumped into my Awfy gem to make a few focussed updates… 10 days later and I’ve basically rewritten it and added a million new things. Sigh.

Terminalwire is now open source! I finally had time to think through the license and landed on AGPL. More in the article about "why", "why now", and a tour of the source code on Github. terminalwire.com/articles/agp...

Anyone have a suggestion for a self-hosted solution for performance monitoring of a Rails app? Ie like www.skylight.io (which hasnt been updated in years it seems)

This looks cool, congrats on the launch @kyrylo.org
