Designing Lock-Free Queues: Inside the Linux KFIFO and Ringbuffer Implementations

How the Linux kernel’s KFIFO achieves a wait-free, lock-free FIFO with a single atomic variable. We walk through the ringbuffer math, the memory-ordering subtlety that makes it correct on weakly ordered CPUs, and what you can borrow for your own high-throughput pipelines.

Architecting Concurrent Go Systems: A Deep Dive into CSP Channels for Production-Ready Pipelines

How Go channels actually behave under load, why CSP pipelines fail in production, and the patterns senior engineers use to make them resilient.
