I've decided to focus my Ruby social media on Mastodon and ruby.social so this account will be pretty quiet. @getajobmike.ruby.social.ap.brid.gy should continue to work if you want to see my Mastodon posts here.

Gem Coop recently published an update on the Gem Fellowship: gem.coop/updates/8/ We're explicitly trying to fund more projects this year. If you maintain an open-source Ruby project, and could use funding, you should consider applying when applications open on December 1st 2026!

It’s almost 2027 and time again for the Gem Fellowship to support Ruby open source. www.mikeperham.com/2026/10/15/c...

This year, Spinel is supporting the 2027 Gem Fellowship. Applications open on December 1, but companies can sign up to sponsor Fellows today. Learn more and join us: spinel.coop/blog/help-us...

@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"

We built uptime monitoring and check-ins to catch the issues that don’t throw errors. They’re included FREE in your Honeybadger account. Set them up in the sidebar of your Honeybadger page—you can be running in a few minutes. #devops

even the mainstream tech media has started to pick this up www.theverge.com/tech/988536/...

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.

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...

Stripe's only social media is on X. Really odd choice.

7 lessons from my 7 years as an entrepreneur😀 1. Don’t quit your job right away 2. Sell to businesses 3. Make what the market wants 4. Do what you’re good at 5. Don’t do lots of tiny bets 6. Charge more 7. Focus on being profitable

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…

Seeing houses and cars set on fire and people terrorized directly instigated by the guy that DHH said makes “beautiful” things happen. If you’re a Rubyist, tell the Rails Core team what you think about them being collaborators and enablers for this. Fucking disgusting.

If you need a script for getting your company off Twitter, I WROTE YOU ONE. Multiple people have used it, successfully, to explain the legal liability your company incurs by forcing employees to be on a platform with child sexual abuse material. I will help you use it. anildash.com/2026/02/23/t...

#GemCoop namespaces are now out of beta! gem.coop/updates/7/ I am *SUPER* excited about this!

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.

Why doesn’t @digitalocean.com support IPv6 for droplets built via custom image? Is there some weird edge case with IPv6 vs IPv4?

Ruby 4.0 warning: it looks like a GC change in 4.0 means Sidekiq may leak memory on every job failure. v8.1.6 will be released tomorrow with a workaround. https://github.com/sidekiq/sidekiq/issues/7006

Javier’s really put in the hard work to grow rubyforum.org from scratch. Another win. 🏆

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

It was a good month with the Ruby Users Forum! www.rubyforum.org/t/monthly-up...

This was a year ago. How’s everyone’s AI coworkers working out today?

I've created Asynq, a new lightweight Sidekiq::Client alternative meant to be safe for use in Ractors. https://github.com/mperham/asynq

Miren (from @evanphx.dev and crew) looks like it is coming along nicely. A next generation PaaS for people who appreciate Heroku's ease. miren.dev/blog/introdu...

This is so, so well-articulated.

I strongly believe that honest assessment is the best way to build trust, and I hope folks feel that the comparisons reflect that.

Ruby Central *really* don’t want you to see this video. They’re now going after Reddit comments linking to it. archive.org/details/gmt-...

Hello, my fellow nerds! @sidekiq 8.1.2, Sidekiq Pro 8.1.1 and Sidekiq Enterprise 8.1.1 are now available. The major change is the new `kiq` terminal UI now available. Upgrade and try `bundle exec kiq` to see it in action!

It's been 4 years since I left Rails core, and my most impactful work has happened since I left. Here's a writeup of it all: kaspth.com/posts/i-quit...

Introducing `kiq`, Sidekiq's new terminal interface, making your occasional admin operations even faster. Give it a try and let me know how to make this an amazing tool for you. https://www.mikeperham.com/2026/03/10/sidekiq-in-the-terminal/

Happy to see Andre finally speaking publicly about the hostile Ruby Central takeover last year. RC is no longer a trustworthy steward for the Ruby community. I don't see how we repair this rift without Shan stepping down, she has been awful as ED. andre.arko.net/2026/03/03/f...

#GemCoop just* launched a public beta for namespaces! gem.coop/updates/5/ * I'm sick and slept until 7pm, so I'm a few hours late, but I'm still super excited about this!

This is the most incredible footage of blue whales I’ve ever seen

rvx installs and runs Rails in 8 seconds, vs. gem exec rails in 18 seconds.

Phlex::TUI is not just a component system. It’s a layout engine, a rendering engine and a reactive component framework all in one. And it’s 100% Ruby with no dependencies.

RubySchema has a new website and all schemas have been updated with improved documentation. www.rubyschema.org

Not bad! The top customer I’m aware of is running 20B/day or avg of 250,000 jobs/sec with a sharded Redis setup.

rv has a big release, with windows support and gem CLI tools! the fastest way to generate a rails app is now `brew install rv; rvx rails new`. check it out: https://spinel.coop/blog/rv-0.5-cli-tools-windows/
