Why the 20‑Year‑Old N+1 Query Problem Doesn’t Apply to SQLite

The article explains that the classic N+1 query anti‑pattern, harmful on client‑server databases like MySQL, is irrelevant for SQLite because its embedded architecture eliminates network round‑trips, turning hundreds of queries into cheap function calls, and examines the performance data and trade‑offs behind this claim.

Why Master‑Slave Replication Lags 5‑7 AM and How a Big‑Data Snapshot Fixes It

The article analyzes why the master‑slave database replication experiences 30‑minute delays each morning between 5 AM and 7 AM, traces the cause to massive inventory‑snapshot jobs, evaluates several mitigation options, and details a big‑data extraction workflow that eliminates the lag while reducing disk usage.

Why Software Engineering Has Never Been Truly Engineered – How Large AI Models May Finally Deliver Real Engineering

The article argues that software engineering has spent the past fifty years merely managing human uncertainty rather than true engineering, and that large language models now make it possible to replace low‑level cognition with energy‑driven intelligence, demanding a shift to an AI‑centered paradigm, closed‑loop automation, and a new focus on scenario‑driven knowledge distillation.

Why Big Data Is Falling Silent: When Scale Can’t Fake Value Anymore

Although national data production reached 52.26 ZB in 2025 and keeps growing, the term “big data” is disappearing because it no longer serves as an organizational credit that hides the need for real value, responsibility, and measurable business impact, especially in the AI era.
