Book Review: Linux Kernel Development, 2nd edition

GNU/Linux is increasingly being seen as a viable, economical alternative to proprietary operating systems, and its market penetration, especially on servers, is increasing. To continue to grow Linux's importance as a secure, low cost kernel, much more serious programmers are needed not only to keep improving it, but to develop stable drivers and most importantly to help continue the rapid Linux march to the Desktop.

Mastering FreeBSD & OpenBSD Security

In this chapter (pdf), the author defines system security, specifically for OpenBSD and FreeBSD systems, but also more generally. He looks at a variety of attacks so that you, as an administrator, will have some perspective on what you’re trying to defend against. He looks at risk response and describes how exactly you can go about securing your FreeBSD and OpenBSD systems. Also, the FreeBSD 5.4-RELEASE schedule has been published.

Language Driven Development

Xactium has published a white paper on Language Driven Development (LDD). LDD is a revolutionary approach to designing and implementing software and systems. LDD makes huge productivity gains by bridging the gap between the way developers think about their problem domain, and the languages and tools that implement the solution.

Linux Rules Supercomputers

The homegrown Linux operating system has come a long way from its origins as a college kid's pet project and computer hobbyist favorite. Refined in recent years by professional computer programmers at IBM, Hewlett-Packard, Novell and Red Hat, Linux now has become so technically powerful that it lays claim to a prestigious title--it runs more of the world's top supercomputers than any other OS.

XMK – eXtreme Minimal Kernel

XMK - eXtreme Minimal Kernel - is a preemptive multitasking real-time operating system for embedded microcontrollers. What makes XMK different from other RTOSes is that XMK is designed to be small first, then scaled up to larger platforms. The BSD-licensed XMK is designed to be highly configurable and comes with a choice TCP/IP stacks: the tiny uIP stack or the more powerful but larger lwIP stack. XMK is available for a number of embedded platforms.
