Apache Kafka 4.0 released 🎉
Download: https://kafka.apache.org/downloads
Release notes: https://dlcdn.apache.org/kafka/4.0.0/RELEASE_NOTES.html
Apache Kafka 4.0 is a significant milestone, marking the first major release to operate entirely without Apache ZooKeeper®. By running in KRaft mode by default, Kafka simplifies deployment and management, eliminating the complexity of maintaining a separate ZooKeeper ensemble. This change significantly reduces operational overhead, enhances scalability, and streamlines administrative tasks. We want to take this as an opportunity to express our gratitude to the ZooKeeper community and say thank you! ZooKeeper was the backbone of Kafka for more than 10 years, and it did serve Kafka very well. Kafka would most likely not be what it is today without it. We don’t take this for granted, and highly appreciate all of the hard work the community invested to build ZooKeeper. Thank you!

So here are a rough set of rules I have decided on for myself, so I hopefully don't fall into the same trap again:
Stay away from immutable distros
Only use deployment tools if they make things easier (Like setting up multiple machines at once)
And only use them for the parts that they actually make easier. I don't need purity here.
Ditch CI/CD pipelines (I want to go back to the simplicity of a shell noscript in a cronjob)
Stuff gets installed in the easiest way possible, preferable a container on a single host with Containerfiles neatly organized in a directory, otherwise throw it into a VM
Not everything needs to be fully declarative. Just doing a backup of state is fine!
Purity is a sin. Accept compromise if it makes something work better for me.

Write a Linux firewall from scratch based on Netfilter: part three - Netfilter module
BackgroundIn the previous article, we examined how to write a Kernel module and load it dynamically into a running Linux system. Based on this understanding, let’s continue our journey to write a Netf
