Is Classifying Distributed Systems as CP or AP a False Dichotomy?

The article revisits the CAP theorem, explains linearizable consistency and strict availability, demonstrates with concrete data‑center examples why the CP/AP split is often misleading, and argues that latency concerns and broader failure modes make the binary classification of distributed systems impractical.

Improving VR Video Clarity: PPD, Tile Encoding, and Future Directions

VR video clarity suffers because the required pixels‑per‑degree far exceed what 4K or 8K spherical streams can deliver, but tile‑based encoding that decodes only the viewport, combined with low motion‑to‑photon latency, distortion control, advanced codecs and AI‑driven projection, promises sharper, lower‑bitrate 6DoF experiences.
