So long, and thanks for all the fish: how to escape the Linux networking stack (11 minute read)
Cloudflare engineers explored the limits of the Linux networking stack while developing soft-unicast, a system for sharing IP subnets across data centers, and encountered complex challenges involving socket binding, NAT, and packet forwarding. After experimenting with multiple kernel-level approaches, they ultimately chose to terminate TCP connections within servers for greater reliability and visibility.

Kafka is fast -- I'll use Postgres (20 minute read)
According to recent benchmark tests, Postgres can handle many Kafka workloads with a fraction of the development effort and cost, performing at 5 MB/s ingest and 25 MB/s egress on a 3-node cluster for approximately $11,514 per year. The "Just Use Postgres" slogan is more relevant than ever because modern hardware allows it to scale absurdly high, making it a practical and simpler alternative to more complex systems like Kafka for many use cases.

AWS to Bare Metal Two Years Later: Answering Your Toughest Questions About Leaving AWS (9 minute read)
Two years after migrating from AWS to bare metal, OneUptime reports over $1.2 million in annual savings, a 76% cost reduction compared to AWS, and 99.993% availability across 730+ days. The move improved latency by 19%, eliminated AWS management overhead, and increased release velocity, while maintaining full SOC 2 and ISO 27001 compliance. OneUptime now runs fully on self-managed Kubernetes and Ceph with selective cloud use for backups, edge caching, and burst testing.
