Virt-Manager (the libvirt GUI) copies a KVM disk and assigns the clone a UUID and MAC. The guest keeps its machine-id and SSH host keys until virt-sysprep clears them.

Amazon S3 has become the de facto API for object storage. After the open source MinIO repository was archived in April 2026, seven credible self-hosted alternatives remain.

Self-hosted SEO now covers crawlers, Search Console dashboards, rank trackers, MCP servers, and local AI. This guide compares the main open-source platforms and which features work without paid SEO APIs.

Migrating an AI assistant is not the same as copying an application config. The hard part is preserving identity, memory, tool behavior, scheduled work, and messaging access without two gateways acting as the same bot.

OpenCode’s command-line interface is built for scripting, CI pipelines, and unattended agent runs. This article is a practical guide to using it in daily work.

Most Claude Code sessions get slow and cluttered for the same reason: every exploratory grep, every log dump, and every “let me check one more file” stays in the main conversation forever.

Ollama is one of the easiest ways to run a local language model, but convenience can conceal the moment when a local experiment becomes a shared inference service that needs better scheduling and observability.

AI coding agents ship features fast, but specs, tests, and code quietly drift apart. This guide covers a traceability model, spec-to-test and spec-to-code mapping, and the CI checks that catch drift before a merge.

Docker Compose and Podman Quadlet solve overlapping problems but come from different design centers, and choosing between them depends on whether you think in application stacks or Linux services.

Running Hermes Agent on a headless server while connecting from a desktop client on another machine requires two server processes and a single client connection.

Docker Compose on a Linux server should start on boot, stop cleanly on shutdown, and survive reboots without manual intervention.

Installing Docker on Ubuntu should be simple, but in practice several Docker-shaped options compete for the same command name, each with different packaging, upgrade behavior, and security implications.

Polling agents are one of the least glamorous parts of AI assistant architecture, but they are also one of the most useful.

Mermaid is a text-based diagramming tool for people who would rather write diagrams than drag boxes around a canvas.

Design decisions for production LLM systems — routing, cost, guardrails, and multi-model orchestration. The layer between running models and building reliable AI applications.

A production AI assistant is not “an LLM with a prompt”. It is a system that accepts intent, keeps state, decides when to retrieve or act, and exposes enough runtime detail to debug failures.
