vLLM Kubernetes deployments fail in production for a reason that has nothing to do with vLLM itself: the standard Kubernetes autoscaling model does not work for LLM inference. HPA scales on CPU and memory. During inference, CPU utilization is low…
Hermes IBC relayer setup is well documented for the happy path: install the binary, run hermes config auto, add your keys, start relaying. What the documentation does not emphasize is everything that happens after that, the gas configuration that the…
Kubernetes for GPU workloads is where most AI infrastructure tutorials stop at kubectl apply and declare victory. Then production arrives: GPU nodes sitting idle because the scheduler ignores NVLink topology, autoscalers triggering on CPU metrics while the inference queue backs…
Kubernetes cost allocation is the problem that appears the moment a cluster bill doubles and nobody can answer “which team spent what.” AWS Cost Explorer shows the EKS cluster as a single line item. The cloud bill tells you the…
Cosmos consumer chains under Partial Set Security are now a live operational decision for every active Cosmos Hub validator. PSS went live with Gaia v17, replacing the old Replicated Security model, and the question is no longer whether to engage…
Ethereum validator consolidation became a live operational decision in May 2025. EIP-7251 raised the maximum effective balance to 2,048 ETH, and the market moved fast: the share of staked ETH held in consolidated validators went from around 2% to over…
The devops interview questions most hiring managers use were written for SaaS companies. They test knowledge of CI/CD pipelines, container orchestration, infrastructure as code, and incident response. A candidate who answers all of them well can still cause a slashing…
Kubernetes validator security is not the same as Kubernetes security. A cluster can pass every kube-bench check, have RBAC correctly configured, Pod Security Standards enforced, and Falco running, and still suffer a slashing event the next time the cluster autoscaler…
When a Web3 company reaches Series A and starts thinking seriously about compliance, the natural move is to bring in an IT audit firm. What comes back is a checklist: patch management, Active Directory review, antivirus coverage, network segmentation, backup…
Every OpenTelemetry tutorial covers the same ground: instrument a Node.js service, deploy the Collector as a DaemonSet, export to Jaeger or Prometheus, add some spans. It is a useful starting point for web services. It is insufficient for blockchain validator…
