Ruby 4.0 introduces ZJIT If you run Ruby in prod, read this. Our Senior System Analyst, Sujay, breaks down the entire evolution in a way that makes VM internals actually understandable. https://www.codemancers.com/blog/rubys-jit-journey?utm_source=social+media&utm_medium=x&utm_campaign=blog_12_02_2026&utm_content=single+image+post #Ruby #RubyOnRails #WebDevelopment #Backend #Performance

The Rails framework inspired many, it's the OG of the modern web development

You don't really need MCP for this. Linux is already a bundle of CLIs, which are typically more efficient anyway. It's amazing how good it is at Linux system administration!

🚀 We released sentry-ruby 6.4.0! This release brings first-class OTLP ingestion support, improved Sidekiq handling, Rack queue time capture, and several bug fixes. 🎉 https://github.com/getsentry/sentry-ruby/releases/tag/6.4.0

We have a basic skill in place, but we should make it even better: https://github.com/basecamp/omarchy/blob/dev/default/omarchy-skill/SKILL.md

The early AI made Omarchy possible simply by teaching me core Linux concepts at an accelerated pace and decoding error messages, but with today's agents I was able to process 100 PRs in an hour the other night. Completely crazy acceleration!

Biggest and fastest change in the 40 years I've tried to make computers do my bidding. And surprisingly, the most fun too!

I only disagree on frameworks. Rails is a great help (I have built pure PHP spaghetti before so I know what you are talking about). And yes, deploy to a single server, Kamal makes this easy now.

Finally, i can see all my rails apps in one great dashboard Errors + Performance + Ai summaries. Thanks @activerabbitai 🐰

Agree there's breathless hype. But if you let that overshadow the incredible gains we've made, you lose. What's happened in the last 3-4 months has been unprecedented in my time using computers.

Rolling out auth with Rails 8 is soo easy.

Neovim is so good now that I gave up a near two-decade love of TextMate with gusto! (After a few days of swearing). Amazing work.

I just processed ~100 PRs for Omarchy in a few hours last night. Unbelievable acceleration. I watch it compress an hour's worth of work into a minute or two. If you can't get excited for that kind of acceleration, I don't know what miracle would impress you.

Why stop at Go? If this is the new compiler, we might as well aim for assembler code! But until we get there, Ruby and Rails are amazingly context and token dense in their expression. Both for the AI and the human.

So if you have a small @rails app or API and want something simpler than managing cloud VMs, it is worth looking at. Build. Push. Deploy. That is basically it. https://docs.bunny.net/magic-containers/guides/ruby-on-rails

Memoizing with ||= in Ruby looks clean and idiomatic, until your domain evolves and "false" becomes a legitimate cached value. Here's why ||= doesn't mean "if unset" (it means "if falsey"), and how that subtle distinction silently kills performance. https://syedaslam.com/posts/when-or-equals-betrays-your-memoization/
