What If We Could Rebuild Kafka from Scratch?
https://nats.io is easier to use than Kafka and already solves several of the points in this post I believe, like removing partitions, supporting key-based streams, and having flexible topic hierarchies.

Protecting NATS and the integrity of open source
Look at the contribution history, basically all active contributors work for Synadia: https://github.com/nats-io/nats-server/graphs/contributors
That's not a healthy / functioning open source community. Less than 30 people have made more than 10 commits; most of the 160 were "drive by" who fixed a single small thing.

Kubernetes on Autopilot: Event-Driven Automation Across Clusters
In today’s dynamic cloud environments, managing Kubernetes resources across multiple clusters can be a complex task. Traditional methods often lack the agility and event-driven architecture needed to respond quickly to changes and automate resource provisioning. This article explores how Sveltos, in conjunction with NATS and JetStream, simplifies multi-cluster Kubernetes management through event-driven automation, streamlining operations and improving responsiveness.

I'll think twice before using GitHub Actions again
hey thanks!
definitely interesting!
I do wonder if this really solves the author problem because by the looks of it , you just have to run meta command and it would run over each of the sub directory. While at the same time , I think I like it because this is what I think people refer to as "modular monolith"
Combining this with nats https://nats.io/ (hey if you don't want it to be over the network , you could use nats with the memory model of your application itself to reduce any overhead) and essentially just get yourself a really modular monolith in which you can then seperate things selectively (ahem , microservices) afterwards rather easily.
