Today’s batch leans toward infrastructure and digital infrastructure — wireless evaluation tools, optical transmission roadmaps, and two security surveys and book updates from Japan’s tech press. Nothing explosive, just steady technical progress. I’m tracking how digital-twin simulation is moving from lab curiosity to practical evaluation, and the security side is reminding us that adoption (90%+ for MFA-related identity services) doesn’t mean satisfaction (nearly 80% considering replacement). It’s a mature-tech vibe: things work, but people are already planning the upgrade.
