GoWroc #59

Hello Gophers!

As the lazy days of summer fade into memory, backpacks get dusted off and pencils get sharpened, it's time for us to dust off GoWroc meetup after the summer break too! Join us this September as we kick off the new school year with two talks. We will be meeting again in the lovely Wędrówki Pub.

And one more thing, as usual, there will be beers 🍺 and pizza 🍕!

📅 Agenda

🕕 17:45 Networking
Let's grab a beer and catch up 🍻

🕕 18:00 Talks

➡️ Arek Ziobrowski: Implementing push-based outbox pattern with Go and Postgres
The classic dual-write problem can pose a challenge to distributed systems - how do you update a database and publish an event atomically? If not handled properly, this leads to lost messages, duplicate processing, and inconsistent state across services.

The push-based outbox pattern addresses this problem, while keeping polling overhead and unnecessary resource consumption to a minimum compared to classical outbox pattern implementations.

During this talk I will go through nuts and bolts on how to implement push-based outbox pattern with Go and Postgres. With recently introduced failover replication slots, this approach becomes even more compelling!

🕖 19:00 🍕🍺 it's pizza time! And another chance to chat with your fellow gopher!

➡️ Wojciech Barczynski: Accelerating Go Development with Claude Code + Open Floor/Discussion
This talk dives into the practical realities of integrating Claude Code into your Go development workflow. I’ll share my journey and lessons learned, covering best practices and common pitfalls for using AI to boost effectiveness.

The core of this session is about collaboration. After a brief overview of my personal experiences, the floor will be open to you. I invite anyone in the audience to come on stage and share your own workflows. Whether you use Claude, a different AI tool, or have a unique approach, let’s learn from each other and discover how to become more effective Go developers together.

🕢 20:00 Networking
