Writing a Linux-style Operating System From Scratch
This entry is part 1 of 10 in the series Writing A Linux Style Operating System From Scratch

Today, we are beginning a new article series: “Writing a Linux-Style Operating System From Scratch.” In this series, we will walk step by step through the process of creating our own operating system from the ground up. Many operating system tutorials stop shortly after the system boots and prints a simple message on the screen.

Building the i686-elf-gcc Cross-Compiler

Together, these tools allow us to assemble, compile, link, inspect, and transform kernel binaries without using the host operating system’s normal compiler target.

Designing a PocketFlow Creator Flow for Queue-Driven RALF Software Development

Purpose This design describes a PocketFlow Creator workflow that accepts a software project folder containing a docs/ subfolder and a project specification, then uses a queue-driven RALF loop to implement the project in ordered, testable increments. The central idea is simple: The LLM may propose.The queue schedules.The gates decide.Git preserves.The human approves high-risk changes. This

Beyond One-Way Power: Upgrading a Linear Regulator to a Two-Quadrant Linear Power Supply

Beyond One-Way Power: Upgrading a Linear Regulator to a Two-Quadrant Linear Power Supply

The “Negative Load” Problem Standard linear regulators, like the ubiquitous LM7805, are designed to be “sinks” of power. They take a higher voltage and drop it down, pushing current out of their output pin to power your circuit. However, they are effectively “one-way valves.” In a modern project—especially one involving motors, large inductors, or external

Is AI Going to Take My Job?

Every major shift in computing has triggered the same fear: “Is this the end of developers as we know them?” When compilers replaced handwritten machine code, some thought assembly programmers were finished. When high-level languages emerged, others predicted the death of low-level expertise. When frameworks abstracted enormous amounts of boilerplate, people claimed “anyone can build
