I wrote an article about how improved design experience will help bolt.new Lovable and v0 enter a mass market :) Because I see a potential for these tools to outgrow "vibecoding" and become a go-to place to make your own software, just for your needs.

I got my Ruby Passport at #sfruby

I had no idea how much preparation goes into organizing a conference. It's been months in the making, and the team managed to pull a 400-people conference in SF off. REMOTELY, from Spain and Portugal! My hat is off to this wonderful and mighty team

The team!

And now the Evil Martians dream team is closing out day 2 of #SFRuby! 🤩👏 The “you can just do things” / “let’s keep building” energy is HUGE in this room! Thank you so much Irina Nazarova for this amazing gift to the community. ❤️ What a conference!

Congratulations to our friends at JSX Tool on the public launch. We are excited to see more dev tool startups in the current YC batch!

Guess the Martian 👽

We’re long-time Rubyists here at Superconductor, so were happy to demo it at San Francisco Ruby Conference, Nov 19-21, 2025! Run Claude, Codex, Gemini, Amp, OpenCode — each with its own fully set up dev env (even Docker) Let agents share screenshots with you 😎 Use it in browser, on iOS, in Slack, from GitHub.

San Francisco Ruby Conference, Nov 19-21, 2025 Ruby/Rails people, if you try it out on superconductor.dev, DM me! We’ll help you set up your dev env if needed.

Thank you San Francisco Ruby Conference, Nov 19-21, 2025 and Evil Martians for an awesome week! Was amazing meeting so many great new people, catching up with others, and especially getting the Inertia Rails crew together with Brian Knoles and Svyatoslav Kryukov ! I hope we can do it again!

Together with community members, sponsors, speakers, volunteers we Evil Martians ran the most epic San Francisco Ruby Conference, Nov 19-21, 2025 last week for 410 people and over 2 dozen Ruby startups! I am now positive we can do anything🔥🔥🔥

San Francisco Ruby Conference, Nov 19-21, 2025 (#sfruby) — Product Demos that surprised me (in the best way) 🤩 I expected great talks, but I didn’t expect the demos to be this good. They turned out to be high-signal snapshots of how real companies solve hard problems with Ruby at scale. What surprised me most

Our new post about migrating Ruby tooling from Parser to Prism for 3.4. Weird edge-case syntax, shifting AST shapes, translation layers, and what it took to make Unparser handle modern Ruby. evilmartians.com/chronicles/unp…

SF is that much more fun when the team is here
