I'm about to take off to London to talk at a @RubyEurope meetup. And tomorrow to @brightonruby - it's my first conference in a while where I'm not presenting. Feels a bit weird :D but I'm really looking forward to fully enjoying a conference for once :).

I wouldn't have dreamt about it a year ago, but it happened. My talk was accepted at #RailsWorld this year. I plan to go deep into LLMs and Model Context Protocol, which I believe can be a first-class citizen in Ruby on Rails. Hope to see you (who managed to get tickets) there ;)

Please watch this!.@jeremysmithco did a GREAT job showing how to go through a code change like a true pro. No matter whether you are changing a payment gateway or ditching Bootstrap for Tailwind - you'll get the how-to answers in this talk.
It was a pleasure getting to put together a brand new talk for Balkan Ruby. I'm thankful for the opportunity!. This one is about the incremental process of making complex changes to software systems in use. 🖥️ Slides: 📺 Video:

14 days and 10 hours until @BalkanRuby .15 days and 16 hours until my presentation - .It will be a bit of a "dinosaur talk" - how to get by after 40, but also massively AI/LLM-focused (and how to have fun AI + RoR). I hope to see you guys there! :).

At #rubycommunityconference I used a dedicated Rails app to show RoR features directly on slides. As ppl asked about it, I extracted the code into @hanaharencar put it the best - it's an app that someone should create. I'll be that someone this time :).

Not to brag, but this may be one of my better articles :) I love features which we get from LLMs and how easy it is to use them in #ruby. Check the article to see how to implement text-based image search in #rubyonrails.
New article on the blog! 📝@realPawelS explores Vector Search – finding items by semantic similarity, not exact matches. Learn the theory, see it in action with image recognition, and explore a photo search app in Ruby! 🚀💡.
