Subscribe ULIX: Literate Unix

A diary documenting the implementation of ULIX-i386

Welcome to the ULIX blog.

Ulix (Literate Unix) is a Unix-like operating system developed at University of Erlangen-Nürnberg. I use D. E. Knuth's concept of Literate Programming for the implementation and documentation. The goal was a fully working system which can be used in operating system courses to show students how OS concepts (such as paging and scheduling) can be implemented. Literate programs are very accessible because they can be read like a book; the order of presentation is not enforced by program logic or compiler restrictions, but instead is guided by the implementer's creative process.

Ulix is written in C and assembler for the Intel architecture. The literate programming part is handled by noweb.

On this page I document my progress with the implementation.

ULIX course at Nuremberg University of Applied Sciences (30.05.2013)


Next term (winter 2013/14) I'll offer a course called "Operating System Development with Literate Programming" at Nuremberg University of Applied Sciences (Technische Hochschule Nürnberg). I'll introduce the literate programming technique, show ULIX code fragments as examples and let the students implement further ULIX components as literate programs.

When that course starts, ULIX should be sufficiently developped, so this gives me a nice deadline for completing the basic code.
