    Archbase

    Archbase

    Open source version of "Fundamentals of Computer Architecture"

    ...The name “archbase” suggests that it could be a baseline architecture or reference templates for projects, possibly spanning front-end, back-end, or full stacks. The repo likely provides starter code, directory structures, configuration files, core modules, and guidelines that enforce certain architectural conventions (e.g. MVC, layered architecture, plugin systems). It might include sample modules or example features to demonstrate how to build on the base architecture, showing how to extend, override, or integrate components in a consistent manner. Developers can clone or fork archbase as a starting point so they don’t need to structure everything from scratch, helping them focus on business logic.

    Flash Linux 0.11 Talk

    Flash Linux 0.11 Talk

    Annotated Unix system source code

    ...The materials break down historically compact and dense code into digestible segments, with diagrams and call flows that trace execution from bootloader to user space. By focusing on a small, early kernel, the series reveals core OS concepts without the complexity of modern subsystems. It highlights how segmentation and paging cooperate, how system calls are dispatched, and how context switches and signals work in practice. The commentary ties C and assembly listings back to architecture specifics, making the hardware–software interface concrete. For learners, it serves as a guided tour that builds intuition for operating system design and prepares them to tackle contemporary kernels with better mental models.
