On March 16th, 1999, Apple computer made two announcements that indicate radical changes in the direction of its OS. One of these announcements was that Apple is releasing the source code to portions of Mac OS X server. The project, called Darwin, has not only released the foundation layers of the operating system, but established a system of user-contributed modifications to the source. Modeled...

Embedded Systems is one of the specialized sites stemming from Dr. Dobb's Journal. In addition to serving as an excellent source of news and product development articles, the site is a portal to many other Internet resources on embedded system applications. Information tailored to specific programming languages, like C++, Java, and many others, is grouped into separate categories. There are also...

The Extremely Reliable Operation System (EROS) "is a capability-based operating system designed to support the security and reliability needs of active systems." The EROS homepage has documentation about the system's development and principles, as well as source code and links to download the software. Developers will find tutorials, installation instructions, and manuals on programming for EROS....

Inferno, created at Lucent Technologies' Bell Labs, is a new operating system that could be the "Unix for the next century." Created by the same research lab that invented C++ and Unix, Inferno's primary goal is to operate seamlessly within a heterogeneous network environment. By abstracting resource interfaces to a common format, Inferno provides a general way to access all resources, both local...

This tutorial, hosted by The Linux Documentation Project (TLDP), covers most of the basics needed to understand and use the Linux operating system (OS). A derivative of UNIX, Linux is a popular OS used in many technical applications. Thus, it is probably not intended for home users. It is mostly text-based, but there are some screenshots and figures of various tools. The author does a good job...

The Linux guru (or guru wanna-be) should bookmark this site. Linux is UNIX freeware available for Intel's x86, Motorola's 680x0, DECS's Alpha CPU and Sun's sun4c and sun4m machines, and is currently being ported to the PowerPC architecture. This meta-site contains documentation in many different languages, links to a great number of applications and utilities that run on Linux, user groups...

Apple released an update to its Mac OS X operating system. The update brought marked performance enhancements and several new features, such as data CD and DVD burning as well as DVD playback; Audio CD burning was added in an earlier update.

Mac OS X (read OS ten) is Apple's next-generation operating system and represents the largest overhaul of the Mac OS to date. Mac OS X promises to bring key technical features such as protected memory (which prevents an individual application from crashing the entire system) to the Macintosh platform for the first time. In addition to completely replacing the underpinnings of the Mac OS, Apple is...

Mac06 (pronounced "Mac oh six") is a POSIX-compatible environment (library and a system kernel) for the MacOS. Its features include a UNIX-like file system using HFS with full Finder integration; POSIX libc.a and #include headers; a curses library; a POSIX shell; many basic UNIX commands, such as cd, cat, find, fgrep, etc.; a software development environment; and sockets for TCP/IP. Mac06 is a...

One of the most important features in current software applications is the undo command, which allows users to revert to previous states in their documents. A relatively unexplored concept involves system undo, a method of restoring settings in a system that were accidentally changed by the operator. This research paper discusses "a model of undo that matches the needs of human error recovery and...
