A badly configured Alertmanager turns every incident into noise: a single unrouted receiver ends with an ignored Slack channel within a week. This article covers, on Alertmanager 0.27 and Prometheus 2.54, how to design the routing tree, inhibition rules, silences and on-call rotations to curb alert fatigue without losing real incidents.
Docker Scout continuously scans container images against CVE databases including NVD and ecosystem-specific advisories, and recommends base-image changes to remove vulnerabilities. Built into Docker Desktop and Hub, it competes with Trivy, Grype and Snyk. Best fit for teams already running end-to-end on the Docker ecosystem.
Grafana Beyla is an eBPF agent that automatically instruments existing applications without touching their code: it observes kernel syscalls and generates OpenTelemetry traces and RED metrics for services written in Go, Java, Python, Node, and Rust. It gives broad, immediate coverage, but it does not replace the manual SDK for business metrics and internal logic.
Cloudflare Workers is no longer an isolated edge function. In 2024, together with KV, D1, R2, and Durable Objects, it forms a complete platform that matches AWS on latency and drops egress fees, though it still falls short on long-running compute and the mature managed databases AWS offers.
Kubernetes 1.31 brings no fireworks, but it closes old debts: AppArmor reaches GA, native sidecars now run enabled by default on their way to stable in 1.33, and DRA moves through alpha toward beta. A practical review from the perspective of someone operating clusters in production.
OPC UA is the standard protocol (IEC 62541) that connects industrial PLCs to IT systems, with built-in security and rich information models that Modbus or Profibus cannot match. Incremental adoption in phases, starting with an observer-mode gateway that leaves existing PLCs untouched, lets a plant running decades-old equipment modernise without stopping production.
Installing Ollama on an Apple Silicon Mac is as simple as running one Homebrew command. Then pick a model based on available RAM (Phi-3 for 8 GB, Llama 3.1 8B for 16 GB) and expose the local, OpenAI-compatible HTTP API on port 11434 to plug it into your own applications.
