@jbaru.ch talks about the big issue with quality and correctness of code written by AI,
and suggests to fix by writing tests but not by LLMs, but with #Cucumber. Do you agree?

@warski.org thinks some pinning issues with Java virtual threads will never be solved.

Have you noticed any noticable impact on your production deployment? how do you solve blocked operations?

Had a fantastic time presenting at DevoxxPL! 🚀

Shared 4 Kafka async patterns powering @wixeng.bsky.social distributed systems:

Public Integration Events, Durable Task Queue, Reliable Task Scheduler, & Long-running Job Iterator.

Thanks for your great questions & ideas!

Teaser slide for my upcoming @devoxxpl.bsky.social talk this Thursday about the benefits and challenges of Async Patterns.

Patterns like Public/Integration events, Task Queue, Task Scheduler and Task Iterator are common-place in @wixeng.bsky.social distributed 4,000 microservices system

Akka is suggestion Event Sourcing as the collaboration pattern for agentic systems? WDYT? Any other pattern you prefer instead?

Loved presenting at #EventCentric on
@wixeng.bsky.social event-driven, domain-driven design: single-aggregate microservices with only public integration events. Boosts dev speed but posed ops challenges we solved.
