Your Cloud Database is a Security Theater

Multi-tenant SaaS storage is broken. Not "needs improvement" broken—fundamentally compromised at the architectural level. The industry sold you row-level security, tenant IDs in every query, and database encryption at rest. Meanwhile, a single SQL injection or privilege escalation exposes EVERYONE's data. One breach, thousands of victims. This isn't security—it's a ticking time bomb with better marketing. BSFS (Block Storage File System) takes a different approach: cryptographic isolation at the

When Birthday Photography Becomes a Template — and Why AI Feels Like an Alternative

In many Chinese shopping malls, birthday photography has quietly become a standardized product. Small studios offer preset birthday shoots at around 300 RMB, usually delivering a single edited image with no raw files.
