Hey! I started using web presentations recently, so I went ahead and built something super fun - a plugin (for Slidev and Reveal.js) that adds interactive slides: ask a question and watch answers coming in, in real time. People scan a QR code and respond from their mobile browsers. It's powered by the free version of our product (AnyCable, I'm a co-founder) - but AnyCable is also MIT licensed, so no vendor lock. It just guarantees that with under 2000 people in the audience, it's gonna work smoothly. I tested it on audiences over 1,000 and also on zoom meetings. It's pretty cool. Ask a question (multiple choice or free input), create a whole quiz. We don't have persistence yet but I'm super open to suggestions for sure!

Also my first npm package ever (thanks to CC, but jeez I'm not a TS dev for sure, but, you know, people and robots helped).

Here's a demo (with explanation and live questions): https://slide-quiz-demo.netlify.app/

Ruby is #5 most used and #3 most loved programming language in the Pragmatic Engineer survey 2025: https://newsletter.pragmaticengineer.com/p/the-pragmatic-eng...

It means that basically, Ruby is huge in the SF Bay thanks to its adoption by startup founders, but it is a lot less popular outside of the Bay Area.

Which is not a bad thing. If at least a few of those startups become big they could sustain the Ruby community with jobs and sponsorship, like Shopify and GitHub do today.

This is the one thing that most developers dont understand when ever we talk about Ruby ( or any programming languages ). The economics of a programming language, you could hate Objective-C all you want but Apple could force people to program in it as long as they hold the 1 billion Active iPhone with 60% to 70% of Apps store spending and online purchasing power.

Edit: The one way to make Ruby popular. Make the best blogging, forums and Wiki software open source and fight the hell out of it for market share. These three category make up a lot of current third party Web consumption usage without being held by big tech.

Stripe is using typed Ruby: they are authors of https://github.com/sorbet/sorbet

Also: lots of other big Ruby shops are on Sorbet, like Figma, One Medical, Gusto etc. We discussed this at the SF Ruby meetup after this talk https://www.rubyevents.org/talks/past-present-and-future-of-...

I have seen that. But on the smaller companies it’s been my experience that Typescript has universal uptake for the frontend while Sorbet and RBS are things to keep an eye on but not getting any interest in using yet.

We're gathering in San Francisco to learn from, build for, and celebrate companies choosing Ruby and Rails for new products today. Come and join the pragmatists and idealists who enjoy writing Ruby.

Or, his fans did!

yay!! amazing ♥

agree

thank you

It's the first Ruby conference in the Bay since 2014, and it has a unique focus on startups. If you want to see companies choosing Ruby and Rails for new products today, join in!

We're sponsored by Chime, Bolt.new, Cisco, Gusto, Intercom, Temporal, Omada Health, Avo and many more. sfruby.com

If you are building a painkiller not a vitamin, then Ruby and Rails ecosystems are great to build for. Existing businesses earning billions and news startups that choose pragmatism. Join the community to learn what the pains are. I’ve been surveying news Ruby startups and sharing results at conferences to learn what’s is the missing open source and tooling that we should build, see for ex https://www.rubyevents.org/talks/startups-on-rails-in-past-p...
