Testing Guides & Best Practices

A practical blueprint for trustworthy ML in 2025: sign datasets and weights, capture SLSA provenance, make training reproducible, ship models as OCI artifacts, gate on attestations, and verify at inference.

Cut app store bottlenecks with SDUI done right: JSON/Wasm layouts, backward-compatible schemas, client capability flags, A/B experiments, offline fallbacks, security hardening, and tooling to debug and verify changes before they ship.

A hands-on, opinionated blueprint for replacing brittle API keys with SPIFFE/SPIRE-based workload identity and zero-trust mTLS across Kubernetes and multi-cloud. Covers SVID issuance, node attestation, Envoy SDS, IAM federation, OPA policy, cert rotation, phased rollout, performance tradeoffs, and pitfalls.

Design and test time‑sensitive software the right way in 2025: monotonic vs wall clocks, virtual clocks for deterministic tests, durable timers vs cron, TTLs and leases, cutovers and backfills, and production patterns to keep systems reliable.

Practical patterns to make APIs and SDKs agent-safe: capability-scoped tokens, JSON‑schema contracts, previews, idempotency keys, reversible operations, rate limits, and human-in-the-loop safeguards for OpenAI tool calling and MCP.

A practical, opinionated guide to building enclave-backed services in 2025: remote attestation, BYOK/HYOK key release via KMS, sealing and rollout strategies, networking and debugging patterns, and vendor options across AWS Nitro Enclaves, Azure, and GCP.

A deep, opinionated guide to choosing and evolving your Postgres multitenancy model in 2025. Compare RLS, schema-per-tenant, and DB-per-tenant across performance, isolation, connection pooling, query plans, per-tenant indexing, Citus/sharding, noisy-neighbor control, encryption, and safe migrations—with a practical playbook for moving between models.

Why RPS-based autoscaling fails for LLMs, and how to do it right with token-rate metrics, prefill/decode separation, KV cache warmth, batching/multiplexing, and GPU right-sizing (MIG/MPS). Concrete Kubernetes patterns with vLLM and TensorRT-LLM.

A practical playbook for adopting merge queues on GitHub, GitLab, and Gerrit—enforce green builds, batch PRs, bisect flaky tests, auto‑revert bad commits, and ship faster in monorepos and trunk‑based workflows.

A pragmatic playbook for resilient, tamper-resistant dependency supply chains in 2025: pin and attest, upstream-mirroring proxies, deterministic lockfiles, vendoring, cache warming, SBOM/SLSA, disaster cutovers, and org-wide registry policies.

Most IDPs degrade into dashboards. This practical guide shows how to build paved roads developers actually use—scaffolding templates, scorecards, policy-as-code, self-serve infrastructure, CI guardrails—and how to measure the impact with DORA/SPACE metrics in 2025.

Cut observability spend by making traces your primary signal: OTel Collector pipelines, log-to-trace enrichment, tail-based sampling, span events over logs, eBPF sourcing, governance, and a step-by-step migration playbook.

How the WebAssembly Component Model and WASI are reinventing plugin systems: define interfaces with WIT, generate bindings with wit-bindgen, sandbox untrusted code, and ship portable components across Rust, Go, JavaScript, and Python for serverless, edge, and embedded runtimes.
