Secrets in Docker: How to Manage Keys

This article walks through the places a secret leaks in a normal Docker workflow, how to check for each one, and the two patterns that actually keep keys out: BuildKit secret mounts for build time, and runtime injection for everything else. The examples use the local agent stack from my earlier Compose article, because it is a realistic case.

Beyond Black-Box Orchestration: Building a Local-First, File-Based Multi-Agent Factory in Python

Learn more about this writer by checking @rumiza-writes's [https://hackernoon.com/about/rumiza-writes] about page, and for more stories, please visit hackernoon.com [https://hackernoon.com]. The Problem: Modern multi-agent AI engineering suffers from heavy cloud API dependency, token budget volatility, and black-box state systems that are incredibly difficult to debug when a runtime pipeline fails midway. The Solution: An architectural breakdown of Agent Business Factory, an open-source, local-first Python framework that executes a complete content-to-product funnel with zero external API dependencies. Core Mechanisms: The framework replaces traditional databases with a transparent, immutable artifacts/ file tree, enforces lightweight run() and execute() code contracts, and uses a CLI-gated human approval queue to safely scaffold out build targets.

Sort and Uniq — How to Turn Noise Into Signal

This article covers every flag, fixes a common misconception about list comparison, and walks through real patterns for log analysis, credential hunting, and ranked output.

Your AI Chat Will Break in Production: 3 Lifecycle Bugs Nobody Warns You About

This story was originally published on HackerNoon at: https://hackernoon.com/your-ai-chat-will-break-in-production-3-lifecycle-bugs-nobody-warns-you-about [https://hackernoon.com/your-ai-chat-will-break-in-production-3-lifecycle-bugs-nobody-warns-you-about]. Your AI chat works in dev and breaks in prod. Three React lifecycle bugs in LLM streaming — stale closures, lost tokens, background kills — and how to fix them Check more stories related to programming at: https://hackernoon.com/c/programming [https://hackernoon.com/c/programming].

Learn more about this writer by checking @alexrixten's [https://hackernoon.com/about/alexrixten] about page, and for more stories, please visit hackernoon.com [https://hackernoon.com]. TL;DR: A stream and React are two different lifecycles — fail to sync them and your AI chat breaks silently in prod. Three fixes: (1) Stream Identity — unique ID per stream, every callback checks if it's still current; (2) Explicit Cleanup — close the connection, mark the chat stale, force-fetch on return; (3) Resume, not restart — pick the stream up from a sequence cursor instead of regenerating. Underlying rule: push-based data shouldn't live in React state directly.
