While "boring" tech doesn't win awards for novelty, AWS Serverless provides the pragmatic foundation most companies actually need. By offloading the "undifferentiated heavy lifting" of infrastructure to AWS, teams can focus on shipping features rather than managing clusters.

This tutorial walks through building StatusD, a self-hosted monitoring service in Go that reads monitored endpoints from JSON, probes them on schedules via a worker pool, records events and incidents in Postgres, sends Teams/Slack alerts, and exposes Prometheus metrics for Grafana dashboards—fully runnable with Docker Compose.

Programmatic access lets you integrate YubiKeys directly into a Go application on Windows. On Windows, `piv.Cards()` uses the built-in WinSCard API to detect connected smart card devices.

Most delivery failures do not happen suddenly.
They emerge through small, reasonable decisions that slowly change how systems behave under pressure.
Understanding delivery behaviour over time helps teams see risk before incidents force attention.

This story was originally published on HackerNoon at: https://hackernoon.com/container-aware-gomaxprocs-what-it-is-and-why-its-important.

In this post, we will dive into how Go schedules goroutines, how that scheduling interacts with container-level CPU controls, and how Go can perform better.

Go 1.25 includes new container-aware `GOMAXPROCS` defaults. These defaults provide more sensible default behavior for many container workloads. They also avoid throttling that can impact tail latency, improving Go’s out-of-the-box production-readiness.
