Great news, everyone! This year's "State of CIDER" survey is out! (see https://t.co/0Xb4aDJiLC)

Please, take the time to share there how you're using CIDER, so we can make it even better!

I'd appreciate it if you shared the survey around, so we can get as much input as possible from our beloved community!

After @EuRuKo in #Sarajevo and @RubyConfAT in #Vienna, I'm starting a third conference: @GoatConf, in #Tuzla, Bosnia and Herzegovina, on 3–5 June 2027.

Free to attend, open to every stack, and built like @pidotdev: a small core that anyone can extend.

Great news, everyone! After a TON of work, RuboCop 1.92 is out with many improvements that make it play better with AI agents (and many other fixes and enhancements). Read all about those here https://t.co/gmHj4FhsqQ

Feedback welcome! Enjoy!

[Bozhidar (Bug) Batsov @bbatsov]

@CodeWithKolin Indeed.

Another problems is that often people opt not to contribute to existing projects as they think it's easier to vibe-code a similar solution for their use-case. Sometimes that might be the right approach, but often it's probably not.

[Bozhidar (Bug) Batsov @bbatsov]

I've been saying the same thing for ages. I've been maintaining some reasonably prominent OSS projects for 15 years now.

Good project leadership is all about vision, consistency, being around and nurturing a community. Sadly vibe-coding often works in the opposite direction.

[(λ. borkdude) 🌱 @borkdude]

Sustained open source is not about "can you create something crazy with an LLM" but how is the project maintained longer term. Who is the person behind the project, are they reasonable people, are they responding to issues in a timely fashion, making sane decisions. Stewardship.

I'm happy to report that https://t.co/lGGMVkSQ55 has been totally overhauled and it's more informative and sexy than ever!

Enjoy the new playground and the retro-inspired looks!

Feedback and comments are very welcome!

Balkan Ruby 2027 is off, and that's a great thing! I'm expecting my third child and will focus on my growing family. You'll have a chance to miss us, and we'll be back in 2028 with new life for our 10-year anniversary. 🙌

Of course, without fluency in the language that your AI agents are using... good luck trying to assess their fluency. ;-)

I get the point Hamilton is trying to make, but I still feel more comfortable using languages where I have deeper expertise, especially for "real work".

[Hamilton Greene 🐷🦀 @SIRHAMY]

Your fluency in a programming language matters a lot less now. AI's matters more.

Pick:

- Mainstream lang (so there's enough training data + docs)
- Good attributes (perf, tooling, types)

Then focus on the product and architecture and let the agents run wild.

The evolution of programming in the past couple of decades:

- 2000 - 2010 -> waiting for the compiler
- 2010 - 2025 -> waiting for the tests
- 2026 - ? -> waiting for my Claude Code account limits to reset

[Dave Thomas @pragdave]

The skills you worked hard to develop as a programmer are just as valid today in the world of AI agents. Link below.
