Cyc — 40 Years of Trying to Write Common Sense by Hand
Cyc is an AI project launched in 1984 to encode human common sense by hand. This article traces Douglas Lenat’s path from AM and Eurisko to CycL, microtheories, OpenCyc, the contrast with LLMs, and the renewed interest in neuro-symbolic AI.

Product DevelopmentMinimizing Release Downtime with Blue-Green Deployment
Blue-Green Deployment runs two environments in parallel so you can deploy and test a new version before switching traffic. This guide covers Nginx, Compute Engine, Cloud Build, instant rollback, database migrations, sessions, background workers, costs, and comparisons with Rolling and Canary.
Digital TwinIs Your “Digital Twin” Just an Expensive 3D Model? The Essence Is State Synchronization, Not Appearance
A high-fidelity 3D model alone does not make a digital twin. This article explains why state synchronization matters, how digital models and digital shadows differ, why real-time updates are not always necessary, when 3D is useful, and five questions to answer before implementation.
AI DevelopmentIsaac Sim Is Not Just a Heavyweight Unity — 4 Decisive Reasons to Move Beyond ML-Agents
Isaac Sim and Unity ML-Agents both support reinforcement learning, but differ greatly in architecture and robotics focus. This article compares GPU parallelism, contact physics, domain randomization, sensor simulation, and ROS 2/URDF/USD integration, while showing where Unity still excels.
AI DevelopmentWhat Is Reinforcement Learning? What Was Happening Behind That “Extra-Dimensional Fight”?
Using our NVIDIA Isaac Sim robot sumo experiment, this article explains reinforcement learning through state, action, environment, reward, and trial and error. It also shows how RL differs from supervised learning and why the robots discovered lariats, folded arms, and aerial attacks.
AI DevelopmentShip Production AI Features Faster with Firebase AI Logic
A practical guide to shipping Gemini-powered AI features with Firebase AI Logic. Learn how App Check, rate limits, Server Prompt Templates, and Template-only Mode can reduce backend complexity—and when RAG, private APIs, trusted operations, or complex workflows still require a backend.
Business & CultureVFA Launches PROSHARE in Vietnam | Exhibiting at VIBE 2026
Vitalify Asia (VFA) is launching PROSHARE in Vietnam. VFA will localize, sell, implement, and support the construction-site information-sharing tool, showcase it at VIBE 2026 in Ho Chi Minh City, and recruit free pre-users ahead of the official release.
AI DevelopmentAI That Reconstructs 3D Shapes from Orthographic Drawings — Using SDF to Capture the Rough Shape
We prototype an AI system that reconstructs 3D models from top, front and side views. Using SDF as a shape draft and exact coordinates from drawings, it achieved 97.1% mean IoU on 500 unseen tests, with 72.5% exact matches on box-based shapes. We also cover validation, limits and next steps.
AI DevelopmentWe Taught Robots "Sumo"—and They Mastered Lariats, Cossack Dancing, and Aerial Combat
We trained two robots to fight sumo in NVIDIA Isaac Sim and tracked their evolution from Epoch 1 to 100. The experiment explores reinforcement learning, Sim-to-Real, domain randomization, and the unexpected strategies the AI discovered—from lariats and kicks to low stances and aerial combat.
AI DevelopmentDeveloped an Agent Skill for estimating ambiguous requirements
Requirement Blueprint is an Agent Skill that helps AI analyze ambiguous customer requirements before estimation. It structures scope, features, flows, tasks, open questions, and risks while separating confirmed facts from assumptions. Benchmarks showed a 26.9% higher average score than baseline.
Digital TwinA Practical FIWARE PoC: Real-Time Temperature Data with Orion
A hands-on FIWARE Orion PoC using real temperature data from Open-Meteo. The article covers NGSI-v2 entities, Smart Data Models, Orion subscriptions, QuantumLeap, CrateDB, Grafana, Docker health checks and practical issues encountered while building an end-to-end IoT pipeline.
3DThe Gundam Base Vietnam – Awakening an Old Passion
A 3D designer revisits Gunpla at THE GUNDAM BASE POP-UP WORLD TOUR in Ho Chi Minh City. From part separation and joint mechanics to tooling, injection molding, and mass production, this article explores Gunpla as a remarkable example of industrial and 3D product design.
