Google just crossed a line at I/O that changes the future of AI forever. https://www.therahulpahuja.com/blog/2026-05-19-google-just-crossed-a-line-at-io-that-changes-the-future-of-ai-forever https://www.therahulpahuja.com/blog/2026-05-19-google-just-crossed-a-line-at-io-that-changes-the-future-of-ai-forever Tue, 19 May 2026 09:00:00 GMT Google's Gemini Omni Flash, shown at I/O, moves past generating content to altering reality itself — and the engineering and trust implications that follow. Mobile App Architecture Comparison https://www.therahulpahuja.com/blog/2026-05-07-mobile-app-architecture-comparison https://www.therahulpahuja.com/blog/2026-05-07-mobile-app-architecture-comparison Thu, 07 May 2026 09:00:00 GMT MVC, MVP, MVVM, MVI, VIPER, and TCA compared for mobile apps: core idea, strengths, drawbacks, learning curve, testability, maintainability, and security considerations. Secure DB Proposal https://www.therahulpahuja.com/blog/2026-05-07-secure-db-proposal https://www.therahulpahuja.com/blog/2026-05-07-secure-db-proposal Thu, 07 May 2026 09:00:00 GMT We propose a reactive, coroutine-native embedded database runtime for mobile (Android/iOS) that unifies storage, sync, event streams, analytics, vector search, and security in one lightweight engine. It builds on proven ideas (e.g. MVCC snapshots, actor-based concurrency, CRDT sync) and modern mobile platforms (Kotlin Multiplatform + Swift). Unlike plain SQLite/Room, this runtime offers built‑in RBAC/row-level security, a push-button sync queue, immutable event streaming, vector search for… MCP Servers, Resources, and Tools: Explained Without the Hype https://www.therahulpahuja.com/blog/2026-04-29-mcp-servers-resources-and-tools-explained-without-the-hype https://www.therahulpahuja.com/blog/2026-04-29-mcp-servers-resources-and-tools-explained-without-the-hype Wed, 29 Apr 2026 09:00:00 GMT A no-nonsense, implementation-level guide for builders creating AI agents, copilots, and automation systems.
