@intertwingly.net How can I learn more about any roadblocks to Sidekiq support in Roundhouse? Giving people the potential to choose their app runtime is super intriguing, removing the GVL for Sidekiq job execution is a massive scalability improvement for CRuby users.
some good advice i got once was "never work for someone you don't want to become"

The performance difference between json 2.7.6 and 3.0.0 is noticeable in Sidekiq's load testing script (~21.0sec to 20.5sec, ~4-5%). That's really hard to do with mature software like Ruby; Jean's optimization work here has been stellar.
I'll probably release the final 3.0.0 version early September, so if you got time please try the RC1 and submit any feedback you may have: github.com/ruby/json/re...
We can only stretch for more thanks to our returning sponsors. Today we share our thanks to Sidekiq and the inimitable @mike.contribsys.com. Sidekiq’s support is what got our funded maintenance program off the ground in the first place. Thank you Sidekiq! hanakai.org/blog/2026/08...

I wrote an update on the dispute with Ruby Central over Bundler and RubyGems. I'm sad it's reached this point, especially since Ruby Central's conferences are a big part of what convinced me to join the Ruby community back in the day. andre.arko.net/2026/07/30/rub…
Ruby Central's Destructive Legacy
At conferences and meetups, and in conversations online, many Ruby developers have asked me about Ruby Central and my disagreement with them. This post is my attempt to answer the questions I’ve been getting over and over, covering: 1) what is Ruby Central doing now? 2) has the dispute over Bundler…

a great summary of the current state of de facto ruby governance from @threedaymonk; I think that if ruby is going to meaningfully remove the influence of the fascists currently in charge of it, it is imperative that gems.coop and the move to fork rails are successful po-ru.com/2026/07/29/i...
It doesn’t matter whether “Matz is nice”

I realized it has been ~1.5 years since I concluded my series of post on JSON optimization. So I got curious how much faster it became since then. 2.7.2 was the last version before I took over maintainership. 2.9.0 was the version I released at the end of the blog series.

Fresco is a ruby-framework that compiles down to a binary via Spinel (matz/spinel). It's super early, but I have something cobbled together that seems to work (and not segfault every fifteen minutes!) Fresco is fresh, it's new and it's inspired by Hanami and @hanakai.org

I strongly believe that honest assessment is the best way to build trust, and I hope folks feel that the comparisons reflect that.
we started Miren because deployment hasn't gotten easier in a decade - and AI coding tools are only making the problem bigger curious how Miren stacks up in the age of AI? take a look: miren.dev/compare
