Hunting Zombie Processes in Go and Docker |
|
|
Docker containers give PID 1 the spotlight, but it's a diva. It needs to manage zombie processes or play nice with an init system like Tini. When Tini stepped in, the container kicked those undead resource hogs to the curb. Suddenly, the server ran like a dream, and those annoying Redis errors bit the dust. All in a day's work. |

Exploring GPU Sharing in Kubernetes with NVIDIA KAI Scheduler and SDG |
|
|
NVIDIA's KAI Scheduler and Exostellar's SDG showcase the nerd ballet of fractional GPU scheduling. KAI slices GPU time like a master chef carving a roast, yet can't keep its focus solo—leading to app skirmishes. In contrast, Exostellar SDG nails resource control, quarantines workloads like a germaphobe, and mingles with various GPUs. It even sports vLLM dual deployments without breaking a sweat. |

I built a Pi‑powered Kubernetes cluster — was it worth it? |
|
|
A Raspberry Pi 5 nestled in a shoebox rack, spinning its wheels with "real" Kubernetes. It sips a dainty 10W but stumbles over hiccups like ARM64 chart voids and single-lane PCIe NVMe antics. Though NVMe drives rocket from 90MB/s to 350MB/s, reeling in those image pulls, thermal throttling and x86-exclusive charts throw a wrench in the works. If silent efficiency, modularity, and a chance to roll up your sleeves matter more than sheer speed, it's a tinkerer's paradise. |
