Andrzej playing chess
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?♟️

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.

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.
We specialize in human legacy Rails apps for years now.
The quality of AI generated rails code doesn’t seem much worse than human code to me.
some human „code tricks” might be even still more difficult to descrypt
the volume/scale is bigger with AI, though

when are you flying? I was accepted too, for early June
One of the best parts of conferences is finally meeting people you’ve only known through GitHub & X.
Got to meet @andrzejkrzywda.bsky.social

Let’s start this Ruby weekend in Poland 🔥
I want to get the recording 😎
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.

Congrats to the whole Unboxed company 👏
We are only 18yrs old now.
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 🤩
Next Ruby conference to attend - @wrocloverb.com
April, 11-13
Great time at the Ruby Community Conference here in Krakow, Poland.

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!

At first, I thought that Part 2 is not necessarily graph-friendly. But actually it is, with some trick like this:
It helped again to store neighbours with their relative direction from the node.

I went with graph traversal algorithm
