Before Hadron, immutable edge systems meant retrofitting general-purpose Linux distributions like Ubuntu, OpenSUSE, or Fedora.Ettore Di Giacinto from Spectro Cloud explains the shift: instead of taking a broad distribution and applying an immutable lifecycle on top,Hadron starts minimal— an operating system designed exclusively to run workloads at the edge. No extra packages, no leftover baggage f...

How do you think about the AI inference stack? Tsahi Duek's colleague coined a framework:RECON— Routing, Engine, Caching, Orchestration, Nodes.Each letter maps to a layer: LLM routers handle request routing, engines like vLLM and SGLang serve models, caching reduces redundant computation, Ray or NVIDIA Dynamo orchestrate across clusters, and Karpenter provisions the GPU nodes.Watch the full interv...

Tanat Lokejaroenlarb, Staff Site Reliability Engineer at Adevinta, explains why EKS in-place upgrades are far more complex than the "one-click" perception many have.He identifies two critical concerns:API deprecation/removalthat can break workloads irreversibly, and thefull node pool replacementrequired during upgrades, which often causes customer downtime or service degradation. Tanat shares why ...
