P.01Python 3.14 shipped in October 2025. The new features worth upgrading for, the ones you can safely ignore, and what changes for existing code when you move.
P.02From .env files to Vault to AWS Secrets Manager: a practical guide to storing credentials, API keys, and certificates without waking up to a breach notification.
P.03shadcn/ui is now the default starting point for React UIs. Here's what it actually is, why copy-paste beats npm install, and how to use it without accumulating a mess.
P.04Caching is high-leverage and consistently misunderstood. How Cache-Control and ETags actually work, why stale content happens, and how to design for it.
P.05A practical incident response process for small teams: severity tiers, on-call rotations, better alerting, and blameless postmortems, no SRE org required.
P.06Leaked credentials are the most preventable breach category. When you need a real secrets manager, which one to pick, and what to do if you're still on .env.
P.07Most teams adopt a service mesh before they actually need one. Here's the decision framework, real cost tradeoffs, and when Istio, Linkerd, or Cilium earns its keep.
P.08The wrong project start leads to scope creep and a client who stops responding. Here's the 30-day onboarding process we use to win agency relationships from day one.
P.09URL versioning, header versioning, and content negotiation compared with real code. Here's how to pick one and retire old versions without stranding clients.
P.10Kafka isn't always the right call for event-driven systems. Choose between Kafka, Redis Streams, and BullMQ based on real throughput and durability needs.
P.11The multi-tenancy model you pick early is hard to change later. Compare database-per-tenant, schema-per-tenant, and row-level security by cost and isolation.
P.12Running totals, rankings, moving averages, and lag comparisons without application loops or self-joins. How window functions actually work, in Postgres.
