Testing Guides & Best Practices

A practical blueprint for real‑time systems without Kafka‑by‑default: CDC with Postgres, transactional outbox/inbox patterns, Debezium, and idempotent consumers to propagate state and keep services consistent.

How SQLite powers edge databases in 2025: patterns for global reads, safe writes, replication with Turso/libSQL, Cloudflare D1, LiteFS, Litestream, and limits.

A pragmatic teardown of background jobs and durable execution: retries, idempotency, timeouts, sagas, backfills, versioning, and multi‑region. When to replace cron/queues with Temporal or Step Functions, plus migration patterns, costs, and gotchas.

A 2025 deep dive into ditching Dockerfiles: Nix flakes, Buildpacks, ko, Melange/apko, and Bazel to ship deterministic, minimal images with SBOMs and SLSA provenance.

A critical, hands-on look at jj, Sapling, and Pijul: stacked diffs, painless rebases, huge-repo performance, and Git interop for piloting them in 2025.

Replace SSH keys and tokens with short‑lived OIDC identities: gitsign for commits, cosign for images, CI federation, SLSA provenance, and a safe rollout plan.

Opinionated, hands-on guide to GPU-aware Kubernetes in 2025: device plugins, gang scheduling, queues/preemption, MIG/MPS partitioning, bin-packing, spot fallback, and orchestration via Kueue, Volcano, and Ray.

A practical, opinionated blueprint for bringing software testing discipline to LLM and RAG systems in 2025: gold datasets, offline and online evals, guardrails, prompt and model versioning, CI regression gates, and telemetry to catch drift before users do.

AI agents are moving from demos to daily dev tools. This article dissects the Model Context Protocol (MCP), how it standardizes tool access, impacts security and observability, reduces lock-in, and what steps teams should take to make their stacks MCP-ready.

Microservices sprawl is expensive. Learn when a modular monolith wins and how to collapse services safely: domain boundaries, repo/layout decisions, build/test pipelines, observability, data strategy, and a phased migration plan.

Ephemeral environments are challenging shared staging. Learn how GitOps, Kubernetes, and database branching enable on-demand, production-like testing—plus pitfalls around data, cost, security, and org change.
