All Tips
Display Technologies: OLED vs. LCD and LTPO
Key: OLED screens have no backlight; each pixel generates its own light, allowing for true blacks.
Mobile Processor Architecture (SoC): The Integrated Brain
Key fact: An SoC is not just a CPU; it integrates modem, GPU, NPU, and ISP into a single silicon fragment.
Lithium Batteries and BMS Systems: Energy Management
Pro Tip: Lithium is highly efficient but unstable; the BMS is the 'brain' that prevents the battery from catch...
Protection Systems: Circuit Breakers and RCDs
Reminder: The circuit breaker protects cables; the RCD protects people.
Electric Power and Power Factor: Real Efficiency
Key: Power is not just voltage times amperage; in AC, the wave phase shift comes into play.
AC vs. DC: The War of Currents
Summary: AC is ideal for long-distance transport; DC is essential for electronics and storage.
Electrical Quantities: Voltage, Amperage, and Resistance
Tip: Think of electricity like water: voltage is the pressure, amperage is the flow rate, and resistance is th...
Hardware for AI: TPUs, NPUs and Tensor Acceleration
Fact: An NPU in a smartphone is designed to consume 100 times less energy than a CPU when performing AI tasks.
Explainable AI (XAI) and Technical Ethics
Key: It is not enough for an AI to be right; in critical sectors like health or finance, we must know WHY it m...
Computer Vision: Convolutional Networks and Perception
Technical Tip: CNNs use filters (kernels) that slide over images to detect edges, textures, and shapes.
NLP and Transformers: The Heart of Language Models
Reminder: The Transformer architecture eliminated the need to process text sequentially, allowing for massive ...
Neural Networks and Deep Learning: The Architecture of Learning
Pro Tip: Deep Learning is an evolution of neural networks that uses multiple hidden layers to extract complex ...
Clean Code and SOLID Principles: Scalable Software
Reminder: We write code for humans, not just machines. Clean code saves money.
API Design: REST vs. GraphQL
Tip: Use REST for simple public APIs; use GraphQL if you have complex front-ends with many relationships.
Docker Containers: Isolation and Portability
Pro Tip: A container is not a virtual machine; it shares the host operating system's kernel.
