Architecture Corner Newsletter Podcast - When systems fail and clients retry, duplicate requests become inevitable. The question isn't whether duplicates will happen, but how your system will handle them. In this episode we will cover: Why duplicate requests are unavoidable in distributed systems and the real-world scenarios that cause them The core concept of idempotency and how it protects your system state from unwanted changes Traditional approaches using request identifiers and hash functions for duplicate detection Storage considerations and time-to-live strategies for idempotency records Domain-driven approaches that leverage business state transitions to achieve natural idempotency Practical implementation patterns and when to choose each approach

Architecture Corner Newsletter Podcast AI coding budgets are getting torched, and 2026 is the year the bill finally came due. In this episode, we dig into how token consumption became a productivity metric (and why that backfired), and what the industry is doing about it now that the free-for-all is ending. We will cover: Why token usage became a proxy for developer productivity — and how Goodhart's Law caught up with it The provider-side shifts (usage windows, model restrictions, pricing model changes) that reshaped agentic coding through early 2026 What's really driving your AI bill: subscriptions vs. API, caching mechanics, and model/thinking-effort tradeoffs Practical tokenmining strategies — from scripting deterministic steps to tuning your harness and mixing models Where the industry goes next as cost-conscious AI development becomes the norm
Are you flying blind with your AI coding agent? In this episode, we detail what actually happens inside tools like GitHub Copilot and Claude Code beyond the prompt you type.
Once you ship a public API, you've made a promise. Keeping it while still moving forward turns out to be harder than most teams expect. In this episode, we will cover: What qualifies as a backward-compatible change, and what doesn't Why does introducing a new API version cost more than just writing new code The real reason clients delay upgrades, and what you can do about it How to support multiple versions without duplicating your entire codebase The adapter pattern is a practical way to isolate version changes at the edges Know more here: https://medium.com/itnext/the-challenges-of-evolving-your-service-api-versioning-8008349a1154 Subscribe, for free, to the Architecture Corner Newsletter at https://architecturecorner.substack.com
The AI development landscape keeps shifting, leaving many developers frustrated as they try to keep up with each new model, tool, and workflow. But what if the answer isn't chasing every update, but building a more intentional approach?
