RubyEvents Guides is now live. Over the last few months, I talked to Rubyists who want to help the community keep going. Some want to restart a local meetup. Some are organizing their first small conference. Some already run events and want to make the next one better.

Had the pleasure of talking with @hansschnedlitz.com about my experiences co-organizing @boulderruby.bsky.social . guides.rubyevents.org/interviews/2... Can't emphasize how cool it is to help run a meetup!

guides.rubyevents.orgDan Moore and Boulder RubyDan talks about wrangling speakers for Boulder Ruby, helping new speakers get started, planning without booking too far ahead, varying meetup formats, and knowing when it is time to step away.

Finally, terminal icons for all the editors. Including my beloved Pi! Let the ricing continue ✨

And thank you to @marcoroth.dev and Rachael Wright-Munn for letting me piggy-back on the RubyEvents platform. It’s the right home for this.

guides.rubyevents.orgRubyEvents GuidesPractical guides for starting and running Ruby communities.

What's next? We’ll add more interviews, resources, tools, templates, and examples over time. If you’ve organized a Ruby meetup or conference, I’d love for you to read it with a red pen. Give it a read. What do you think? guides.rubyevents.org

They are not perfect. They are living documents, and they will never be complete. But they are a start.

Thank you to Travis Dockter for conducting the initial interviews and letting me use them. Thank you to all the organizers who lent their voices to the project - @jeremysmith.co , Hana Harencarova, Cirdes Henrique, and many others.

That’s what RubyEvents Guides is. The guides are based on more than a dozen interviews with experienced conference organizers. They collect practical hints, tools, resources, and long-form advice you can work through at your own pace.

Most importantly, they make the work visible. The budgets, the venues, the speaker wrangling, the scheduling, the weird edge cases. All the stuff that makes an event happen before anyone shows up.

The awkward part is that event organizing is still pretty opaque. You can want to help and still get stuck quickly. Where do I find a venue? How do I get speakers? What format should I use? Who can I talk to who has done this before?

There are posts, writeups, and bits of advice scattered around. But I kept wanting something more complete. Something grounded in lived experience, not generic “community building” advice. Something that takes the knowledge in organizers’ heads and makes it easier to find.

I live in the terminal and I like things pretty. But there's no icon font for AI logos - Nerd Fonts has git and your distro, nothing for OpenAI or Anthropic. So I made one. 300+ AI provider logos as a glyph font for your terminal, statusbar and prompt. Link below 👇️

I don't care much for the project TBH but this write-up feels refreshingly honest about what worked and what didn't in agentic engineering. Nice change compared to all the 'look at my amazing AI workflow!!' posts

hansschnedlitz.comSpatial Queries with SpatiaLite and Ruby on RailsSpatiaLite is a great alternative to PostGIS/PostgreSQL if you want to stick to SQLite. Previously, we set up SpatiaLite in a simple demo application. To jog your memory, here’s what we’re building.

8 Apr

Here's a post that is equal parts "spatial queries in SQLite are neat" and "here are the weird corners you will absolutely run into." If you're using Rails with SQLite and want spatial queries without switching to PostGIS, this will save you some time. www.hansschnedlitz.com/writing/2026...

I've built a bunch of maps over the past few months, so I wrote up what spatial data in Rails with SQLite actually looks like. Usually people say PostGIS. Fair enough. But SQLite + SpatiaLite is pretty capable too. hansschnedlitz.com/writing/2026...

Copy-pasting code is underrated. Better than adding another dependency. Better than vendoring. Now I point an agent at a library and say "take their approach, adapt it for our project." The result fits like a glove. It's a great time to copy-paste. More on the ol' blog 👇️
