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.
Ruby.social
If you are interested in the Ruby programming language, come join us! Tell us about yourself when signing up. If you just want to join Mastodon, another server will be a better place for you.

In 2025, we hit the conference circuit—RailsConf, Laracon, ElixirConf, to name a few.

We shipped smart "Just Enough APM™" dashboards, Insights Alarms, an EU data region, plus integrations with @incident.io, @rootly.com, and more.

Thanks for a great year. See you in 2026! 🧡

🌸 Here’s your State of Hanami for 2025.

We took our first steps into a new era: we made a substantial release, began unifying our ecosystem, launched our sponsorship program, and saw a real uptick in community activity.

Read all about it! hanamirb.org/blog/2025/12...

What’s really amazing about vibe-coding is how people are replacing programming languages which are strictly deterministic with human speech which is highly ambiguous and expect programming to be faster and better.

I spent the last few days migrating Sidekiq’s wiki content to a new @bridgetownrb.com app. I loved reading the docs and learning a totally new to me Ruby tool. That knowledge is literally the value I provide as a senior engineer. Why outsource that to AI?

I became a software engineer because writing code is fun. Thinking through hard problems, designing elegant solutions, seeing the things you’ve built working for the first time… these moments are all deeply satisfying, so why in the world would I ever surrender them to AI?

SVG icons have been "solved" myriad ways, but I find them all lacking.

Inline SVGs? Bloated DOM.
<img> tags? Can't change colors.
Icon fonts? Blurry at certain sizes, a11y issues.
CSS background-image? Still can't change colors.

But, today there's actually a perfect solution...

Am I missing something or did they just say “we can’t release our bylaws because we don’t know how to add content and we’re redesigning our website”?
