There would be no wroclove.rb without our amazing supporters 💫 Arkency has been with us since the very first edition, and we’re extremely grateful to have them on board again this year - thank you for making our conference possible since day one! (1/3) arkency.com

Since 2012, @andrzejkrzywda.bsky.social has been shaping wroclove.rb💎 A long-time DDD advocate, he recently took the stage with a keynote on how DDD fits into Rails ➡️ check it out youtu.be/3IlWgwkTV0s Andrzej’s chessboard is coming to wroclove.rb - fancy a game with him in April?♟️

Save the date! @wrocloverb.com is back on April 17–19, 2026 💎 We’ve got big plans to make this edition unforgettable. Stay tuned for updates - and see you in Wrocław!

Our crew doesn’t just organize wroclove.rb - we also share our knowledge at other conferences 💡 This year, our co-organizer @jan.dudulski.pl took the stage at @friendlyrb.com with his talk "Back to Simplicity" - huge thanks to our friends there for having him!

Happy to share that I’m speaking at the ParisRb meetup on Tuesday, July 1st I will talk about Rails and DDD, my lesson from the last 15 years of combining them together. meetu.ps/e/PbpBx/dVM8l/i

20 years in and people still fall in love with Rails

Time goes by and we're ready to show off all the great talks that we've had at #wrocloverb this year 🌟 Let's begin with @joel.drapper.me presentation on typing in Ruby and Literal - set of tools to help you write more expressive, confident Ruby. Enjoy!

Rails was the AI of 2000s. ✅Creating apps became much faster. ✅Testing business ideas became cheaper. ✅Business loved it. ✅VCs loved it. ✅Divided devs into enthusiasts and sceptics. But when apps grew? That’s when things got tricky.

One of the best parts of conferences is finally meeting people you’ve only known through GitHub & X. Got to meet @andrzejkrzywda.bsky.social @sethhorsley.bsky.social @fractaledmind.bsky.social @joel.drapper.me #wrocloverb

Let’s start this Ruby weekend in Poland 🔥

types in Ruby value objects hot or not? from @lucianghinda.com recent blogpost

DDD is AI-friendly clear modules and boundaries makes it easier to reason about for both humans and AI (smaller context!)

New blog post on the Arkency blog! Piotr has just published his first post, sharing our journey to stabilize a nearly 10-year-old Rails application for a client. The app was using a microservices pattern—but not in the most effective way. blog.arkency.com/is-your-rail...

I posted 2 tweets on X today and X stopped working. Sorry everyone 🤷‍♂️ (or not)

A friendly reminder that as Arkency we help with modernizing existing (legacy) Rails apps. It doesn't matter if the Rails app was originally created by human devs or AI. As such, we're big fans of AI, more business for us 😎

„You must be one of the oldest Rails agencies” the message I just received never thought about it this way, but yeah

Shoutout to @szymonfiedler.bsky.social! Szymon will present a practical methodology for verifying business logic equivalence during rewrites, focusing on isolating side effects and leveraging existing system behavior as a specification. A cherry on top: real-world examples guaranteed 🤩

Great time at the Ruby Community Conference here in Krakow, Poland. Thanks to the organizers, speakers and sponsors 🙏

#webdevelopment #ruby There is a 6 minutes podcast that i share with some junior developers once per few months. I figured out i should share it there too: open.spotify.com/episode/5mX2... Main wisdom of that one: "don't attach emotionally with your code".

just published a new blog post about Rails Event Store and how you can easily integrate it in a new or existing app from ActiveRecord callbacks to a pub sub system! xamey.xyz/post/?sha=2c... @lukaszreszke.bsky.social @andrzejkrzywda.bsky.social

Advent of Code, day 4 I went with graph traversal algorithm

Catching up with Advent of Code Day 3 is such a lovely opportunity to use parsing with Ruby Parslet gem. It has a nice combination of being a DSL and still writing Ruby.

To my chess fans IM Levy (Gotham Chess) got a mental breakdown after losing to me youtu.be/3yYuNefwxRA?...

Annual reminder on how to get anything done: blog.arkency.com/2015/03/how-...

Advent of Code with Ruby with DDD sounds like overkill still, seriously considering

pair programming ❤️

You really should, best conference IMHO. Wroclaw strolling will free your mind (compared to other cities, not nature) given the amount of space between the buidlings. Talks quality is higher than the other ruby confs I've been too.

Uhh my favorite tech conference will be in April. Not too big, best talks, supremely walkable, beautiful city. Been there multiple times.

Spoiler alert . . . . Is your app also noticing huge traffic from AI bots?

Objects as clerks Nice metaphor by Trygve Reenskaug (the inventor of MVC and DCI)

During a Call of Cthulhu RPG session last weekend. It was 1921. Don’t judge me.

It does tell about a person, which tool they open to support a group discussion. number people - Excel code people - IDE brainstorming people - Miro planning people - Trello structure people - Mind Maps process people - Jira Which are you? I’m between IDE, Mind Maps, Miro

This Ruby conference is closest to my ❤️ See you there?

what happens when you serialize Ruby Infinity object to JSON? what if it’s a value in the Hash? good lessons about it in this commit github.com/RailsEventSt...

Given how much code is now generated by LLMs, does the readability of the language matter? My subjective opinion is that Ruby is very readable and can even be „parsed” by business humans. Does it make Ruby or similar language more LLM-era friendly?

The difference between Turbo Streams and Turbo Frames blog.arkency.com/the-differen...

Building a set of code samples to learn the @bsky.app API, and will occasionally update the thread here with links to those examples. Repo is here: github.com/skillstoprac...

Reviewing a draft of a new blogpost at the Arkency blog „The difference between Turbo Streams and Turbo Frames” This choice sometimes confuses Rails/Hotwire devs.

This is a difference between Ruby and Python There is no such thing as a global method in Ruby (and I like it) zverok.substack.com/p/there-is-n...

If you are a senior Rails dev, wondering if Event Sourcing and DDD is for you, then this online workshop might be a good opportunity. products.arkency.com/from-legacy-...

3 IT books that never get old

Are Starter Packs a BlueSky invention or it existed in such form in other social media? It’s pretty cool and solves a lot of onboarding challenges.

20 years with Ruby and I’m still both excited about Ruby metaprogramming and scared how it can be overused

perfection

got rid of redis in my project the last usage was ActionCable and it seemed fine to switch to the postgresql adapter

The skills of a valuable programmer: 1. Learn to write code 2. Learn to read code 3. Learn to read human messages 4. Learn to write to humans 5. Learn to listen to humans 6. Learn to speak to humans Start from 1/10 in those skills and get to 10/10.

is there a name for a role which combines both programming and sales? can be in German

I have been curating my starter packs, so even if you used one previously, you might want to check back from time to time. Good list of Ruby folks here, and if you look at their following/followers you’ll find even more. go.bsky.app/HD2Ty2o

At Arkency, we’re all about rescuing Rails legacy codebases. With so much AI-generated code out there, it’s like AI is our best business partner ever.

my new hobby is brainstorming some code with chatgpt without writing any line yet here debating on how to implement a Chess game with some more advanced concepts
