Dennis Ritchie, Father of C and Co-Developer of Unix, Dies
Dennis Ritchie, the creator of the C programming language and co-developer of the Unix operating system passed away on October 8 at the age of 70, leaving a legacy that casts a very long shadow. Linus Torvalds once said, in reference to the development of Linux, that he “had hoisted [himself] up on the shoulders of giants.†Among those giants, Dennis Ritchie (aka dmr) was likely the tallest.

It's available in several forms: The book in PDF, for pri
ACPICA - The ACPI Component Architecture Project
ACPI Component Architecture (ACPICA) is a reference implementation of the Advanced Configuration and Power Interface (ACPI) specification. This implementation simplifies complex ACPI operating system implementations by integrating it directly as a kernel-resident subsystem, without changes to the core ACPICA code. Introduction to ACPI Architecture Download With advanced power management (APM), pow
6.828 / Fall 2006/ Overview
6.828 teaches the fundamentals of engineering operating systems. You will study, in detail, virtual memory, kernel and user mode, system calls, threads, context switches, interrupts, interprocess communication, coordination of concurrent activities, and the interface between software and hardware. Most importantly, you will study the interactions between these concepts, and how to manage the compl
Device Polling support for FreeBSD
Device Polling support for FreeBSD This page contains material related to some recent (Feb. 2002) work I have done to implement polling device driver support in FreeBSD. This work has been done in cooperation with ICSI in the context of the Xorp project, and in some aspects can be still considered work in progress. The code is now in the FreeBSD CVS repository both for -current and -stable, so you
