Why Chinese CPUs Require Full Memory Population: Chiplet NUMA vs Intel's Monolithic Design

Domestic Chinese server CPUs using chiplet architectures create many fine-grained NUMA nodes per socket, each needing local memory; unlike Intel's monolithic single-NUMA-node design with mature interconnects and kernel optimizations, partial memory population forces remote access over slower chiplet interconnects, causing severe performance drops.

Ontology-Driven NL2SQL: Semantic Governance Is the Real Prize, Not Accuracy

This article analyzes ontology-enhanced NL2SQL systems, showing that their true value lies in forcing enterprises to explicitize and govern business semantics—metrics, dimensions, rules—rather than merely improving SQL accuracy, detailing modeling components, construction pipelines, online execution architectures, and the shift toward ontology-as-tool-interface.

From Monoliths to AI Agents: Architecture Evolution's Two Patterns and New Challenges

This article traces software architecture evolution from monoliths through primitive distributed systems, SOA, microservices, and cloud-native, highlighting two recurring patterns — finer decoupling and stronger fault isolation — and a shift from zero-failure goals to designing for resilience, while outlining four unprecedented challenges AI agents introduce: semantic hallucinations, stateful context, dynamic orchestration, and observability gaps.

Turing Winner Stonebraker: Why LLMs Won't Replace Relational Databases & AI Agent Pitfalls

In an 80-minute interview, Turing Award winner Mike Stonebraker argues that relational databases will absorb AI workloads, explains why Text-to-SQL fails on real enterprise data due to schema corruption and access controls, details DBOS's persistent workflow approach for AI agents, and discusses saga patterns for compensating transactions, graph database limitations, and the future of open-source AI.

Why the Creators of Linux, Python, Redis, Nginx & SQLite Are True Geniuses

The article argues that creators of foundational software like Linux, Python, Redis, Nginx, and SQLite are true geniuses due to their exceptional abstraction skills and system-level boundary control, illustrated by real-world cases where their minimal, convergent designs outperform modern complex solutions, and warns that over-reliance on AI tools erodes deep system understanding essential for solving hard production issues.
