Merkle Asset Digesting in the Astro 5 Content Layer
How we wrapped Astro 5's glob() loader with composite Merkle asset digests, Vite FSWatcher proxies, and localImagePaths SVG pruning for sub-200ms HMR.
Professor for Industrial Informatics @ UAP • AI-Based Software & Systems Engineering
At FH Upper Austria (Campus Wels) and in industrial practice, I research, teach, and architect AI-based software systems, agentic engineering workflows, and cyber-physical simulations. Explore my latest technical articles, interactive slide-as-code keynotes, university courses, and open-source projects below.
Explore my latest insights, tutorials, and dev logs on software engineering, artificial intelligence, knowledge graphs, and system architectures.

How we wrapped Astro 5's glob() loader with composite Merkle asset digests, Vite FSWatcher proxies, and localImagePaths SVG pruning for sub-200ms HMR.

How we unified technical diagrams into three-band figure cards with pan/zoom inspection, font-weighted SVG scaling, and AST Soft Nordic Pastel governance.

How we replaced fragile 8px hit tests with bounded Voronoi proximity picking, an 8px touch deadzone, and 8-sector tooltip repulsion across 5 graph engines.

How we unified hover tooltips, 60fps drag physics, dynamic hop z-ordering, and 750ms sine-eased transitions across D3, Vis.js, Cytoscape, Sigma, and 3D.

How we replaced unweighted k-hop BFS with focus-budgeted effective hop distances, logarithmic hub-degree penalties, and parametric decay in web graphs.
