The best funnel builder on the planet, ClickFunnels is one of the largest Rails monoliths. Together, we fixed a problem that isn't always a priority, but which has productivity costs that can be an annoying drain if allowed to multiply: flaky tests. evilmartians.com/chronicles/f...

Thank you, @euruko.org 2025 and beautiful Viana do Castelo for the fantastic event, execution and energy of the Ruby community! From so many @evilmartians.com 💙

Every large enough Rails app has extracted some services for performance and scalability reasons. You can do this without losing the joy of building with Ruby and Rails. Keep the recipes in Ruby, and only upgrade the "dumb" (unaware) kitchen tools. Here's how.

Scaling Rails doesn't have to mean rewrites or microservices. Read this new post to see how and why to keep your business logic in Ruby, while firing up your kitchen with Go, C, and Rust! evilmartians.com/chronicles/b...

⚠️critical CVE in set of popular NPM packages: socket.dev/blog/npm-aut.... They contain malware that injects code & replaces transaction addresses; user wallet funds redirect to attacker-controlled addresses! check malicious versions in projects’ node_modules: “grep -r "const _0x112" node_modules”

12 years of PostCSS → 400M+ downloads/month. Lessons from the journey: collaborate early with other maintainers, keep libraries build-free for easier debugging, and focus on simplicity. Great read on OSS longevity 🌟 #OpenSource evilmartians.com/chronicles/w...

Evil Martians cut Whop’s CI time in half in one week. This post walks through profiling to find hidden loggers, taming factory overhead, switching to smarter parallelization, and fixing the flaky tests that surfaced along the way. evilmartians.com/chronicles/t...

Adopting a circuit breaker pattern from day one? Our new post explains this approach and how it can now fit into Ruby projects of any size. Plus, we showcase a gem to help you contain cascading failures before everything flat lines. evilmartians.com/chronicles/c...

I was impressed by how smooth the CFP process felt for SFRuby. So I'm glad this is now open source! It's fun to poke around in there, particularly that they're using Associated Objects in one place 🥳 github.com/evilmartians...

We’re launching a new series of full open source apps, starting with Redprints CFP, built with Rails + Inertia.js! It powered our SF Ruby Conference’s proposal management process. Now, it’s your turn! evilmartians.com/chronicles/r...

We at @evilmartians.com created palette generator for designers, based on the most advanced color math (OKLCH, APCA), which we’ve started to understand well. harmonizer.evilmartians.com Here’s a video example of how to use it. www.youtube.com/watch?v=7nvw...

Founders, forget the “AI requires massive resources” myth! Recraft is a lean female-led team that went from idea to $30M Series B by zigging when the giants zagged. Smart constraints = superpowers.

Working with Medplum confirmed what many devtools founders know: pitching a product to industry buyers is the real challenge. Their ace team built an impressive open source healthcare platform—we helped reframe how they showcase value to medical decision-makers. evilmartians.com/chronicles/d...

Martian CEO @inazarova.bsky.social is talking to founders choosing Rails and @marckohlbrugge.com was an obvious success story. And his advice isn’t about “hustle” or “grit” ...but curiosity, speed, and a willingness to be publicly wrong.

Using SaaS for image processing comes with plenty of risks. Your post-paid bill may badly surprise you after a sudden traffic spike, bug, or DDoS attack. Pricing can work differently: pre-paid, no “per-image” billing, soft limits. buff.ly/QtQpjQb

The brilliant team Julia & Freddie (who worked on GitHub Copilot) founded Quotient AI in 2023. To double down on dev experience, they teamed with us to design and launch PromptLab: a playground for prompt iteration. Insights from our work and a new post 🧵

Tauri has a very sustainable dev flow as it can catch most errors at compile time. But what if you want to go beyond the basic setup with a web app and Tauri backend? Like background file syncing, the filesystem, or the network? evilmartians.com/chronicles/m...

Released Nano Stores 1.0, my minimalist state manager for extracting logic from React components. The new version only introduces effect() and drops support for Node.js 18. This release is more about stabilizing the API. github.com/nanostores/n...

I’ve been on open-source for 10 years now, and that post is really complete. As always, @en.sitnik.ru is someone to respect. From my experience, I would just add that once you go open-source, you can’t go back – it’s a bad and good matter.

PostCSS creator @en.sitnik.ru has 20+ years of open source experience with multiple success stories. In this new post, he shares practical steps on how to make your open source popular—and why to make open source at all. evilmartians.com/chronicles/h...
