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.

Andrzej Krzywda @andrzejkrzywda.bsky.social · 23/04/2025

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

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...

Is your Rails application special?

Hi, we're Arkency and it's our blog with meaty content.

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 🤩

#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".

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.

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.

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

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.
