👋 Embedded Systems & Linux Blog — Yair Gadelov
Here I share in-depth articles, practical guides, and personal insights from my work in embedded systems, Linux/Yocto BSP development, real-time firmware, and system-level software engineering.
You’ll also find explorations of adjacent domains — from kernel drivers and PCIe bring-up to data pipelines, machine learning for trading, and software architecture best practices.
Typical topics include:
This blog is both a knowledge base and a personal journal of my engineering journey —
from hands-on hardware bring-up to complex embedded Linux platforms and beyond.
