Educational materials, tutorials, and lecture notes on statistics, machine learning, and AI, plus conference talks and presentations. This includes fundamentals of AR, MR, and VR development (Machine Learning for data science, VR Fundamentals & WebXR Development, 3D Interaction Design, Performance Optimization), as well as research-based teaching on GenAI applications in Virtual Reality, eye tracking and bio sensors in immersive systems, and digital sovereignty and privacy-preserving technologies.
A best practice is a crystallized solution to the problems of its own time. When the context moves, the solution stays — and a practice that once saved projects becomes the pattern that breaks them. Why this happens, the three forces that make it inevitable, and how to tell a durable principle from a dated practice.
Your workflow optimizes assets and tries to push the result back to main, but the push is denied with HTTP 403 and git exit 128. The cause is almost always the default GITHUB_TOKEN being read-only on newer repos. Fix it with a two-line permissions block and understand the check_run inputs that were silently ignored.
A handful of thin, low-value pages were dragging down your AdSense site's crawl budget and index quality. Instead of deleting reachable content, apply a reversible noindex: build a word-count gate, warn vs fail thresholds, and take hopelessly thin leaves out of the index while keeping them online.
A CI script that verified every image in your compose file starts failing for one tool, and the tool's tags all 'don't exist' — because they live on quay.io, not Docker Hub. How to validate image tags across registries with anonymous bearer tokens and HEAD manifests.
A self-hosted GitHub Actions runner reports online with the right labels, yet your queued run never gets picked up. The real culprit is usually not the runner at all — it's a GitHub-side job that never got materialized. How to diagnose the ghost queue and make your deploys re-triggerable.
A nightly Dgraph backup that 'restored' to 2.7 million keys nobody could query. Why community dgraph restore can't materialize the Enterprise binary backup format, how to prove a backup is real before you need it, and the RDF export that actually loads.
