This article explains the common JVM OutOfMemoryError categories, analyzes a real‑world GC overhead limit exceeded incident, and demonstrates how applying the fail‑fast principle can help developers detect and resolve memory‑related failures more efficiently.
This article walks through the root cause analysis of an OutOfDirectMemoryError in a Netty‑based MQTT IoT broker, detailing how to detect off‑heap memory leaks, monitor them with BTrace and custom metrics, and apply proper ByteBuf release and configuration fixes.
This article details how a team of web developers chose Electron to create a cross‑platform PC client for the teaching tool "Classroom Optimization Master", describing the technology stack, successive architectural evolutions, performance improvements, and lessons learned about modular design and hot updates.
This article recounts the evolution of the Class Optimization Master Android project—from a dual‑end, no‑design prototype to an MVP‑based implementation and finally a modularized architecture—highlighting pain points, solutions, and practical steps for improving code boundaries, build times, and reusable modules.
This article surveys the evolution of artificial intelligence, clarifies weak versus strong AI, explains when machine learning is appropriate, and provides a step‑by‑step TensorFlow tutorial that trains a fashion‑MNIST image classifier using Docker and Python.
