In this year's #JCrete hackday I decided to toy claude code to start incorporating genAI tools (that go beyond slack-chats/mail/meeting summaries, etc.) in my day to day work. My first attempt was kind of a disaster and I ended up writing a script to the job, but today I had my first success story.

Believe it or not, the next release of Quarkus will be the 365th release since Quarkus became a thing, 6 years ago. It will be one year of release days! I released the large majority of them but this will change a bit with @janmartiska.bsky.social taking the responsibility for some LTS streams!

Finally put some time aside and watched @mukel.bsky.social's and @alina-yurenko.bsky.social's presentation from DEVOXX.
Very interesting and well delivered, now I need to find some time to toy with it as well :)
