RISC OS is an operating system originally created by British manufacturer Acorn Computers for their ARM based computers ranging from Archimedes to Risc PC, replacing Arthur which was shipped on the first models.
The operating system takes its name from the RISC architecture used on supported systems.
Features
* Stored in ROM - This allows for faster bootup (sub-30 seconds, the record is 2 seconds), safety from corruption and security against viruses. Versions 4 and 5 are stored in 4 MiB of Flash ROM, enabling operating system updates without having to physically replace …

As part of its move to Intel chips in early 2006, the Cupertino-based company largely abandoned its practice of using custom motherboard chipsets to support the primary CPU in its Macs. Instead, it began to rely on slightly tweaked versions of industry-standard chipsets offered by Intel to the broad range of PC manufacturers that develop Intel-powered systems.
For instance, while Apple’s existing line of MacBook and MacBook Pro notebooks are unique in that they run the Mac OS X operating system, they’re architecturally based on the same run-of-the-mill processors and chipsets …

Mono is a project led by Novell (formerly by Ximian) to create an Ecma standard compliant .NET compatible set of tools, including among others a C# compiler and a Common Language Runtime. Mono can be run on Linux, BSD, UNIX, Mac OS X, Solaris and Windows operating systems.
Microsoft has a version of .NET available for FreeBSD, Windows and Mac OS X called the Shared Source CLI (Rotor). Microsoft’s shared source license may be insufficient for the needs of the community (it explicitly forbids commercial use). The Mono project has many …

In computer networking, xinetd, the eXtended InterNET Daemon, is an open-source daemon which runs on many Unix systems and manages Internet-based connectivity. It offers a more secure extension to or version of inetd, the Internet daemon.
xinetd features access control mechanisms such as TCP Wrapper ACLs, extensive logging capabilities, and the ability to make services available based on time. It can place limits on the number of servers that the system can start, and has deployable defence mechanisms to protect against port scanners, among other things.
On some implementations of Mac OS …

In case there were any doubts that Apple was exploring the use of advanced multitouch gestures under Mac OS X, a recent Apple patent application authored by Wayne Westerman (of Fingerworks) shows mockups of a Mac OS X gesturing control panel with options to configure standard trackpad, basic multito…

The Linux-HA (High-Availability Linux) project provides a high-availability (clustering) solution for Linux, FreeBSD, OpenBSD, Solaris and Mac OS X which promotes reliability, availability, and serviceability (RAS).
The project’s main software product is Heartbeat, a GPL-licensed portable cluster management program for high-availability clustering. Its most important features are:

no fixed maximum number of nodes - Heartbeat can be used to build large clusters as well as very simple ones
resource monitoring: resources can be automatically restarted or moved to another node on failure
fencing mechanism to remove failed nodes from the cluster
sophisticated policy-based resource management, …

Gobby is a free software collaborative real-time editor available on Windows and Unix-like platforms. (It runs on Mac OS X using Apple’s X11.app). It was initially released in June 2005 by the 0×539 dev group.
It features a client-server architecture which supports multiple documents in one session, document synchronisation on request, password protection and an IRC-like chat for communication. Users could choose a colour to highlight the text they have written in a document. Gobby is fully Unicode-aware, provides syntax highlighting for most programming languages and has basic Zeroconf support.
A dedicated …

Wine is a software application which aims to allow Unix-like computer operating systems on the x86 architecture to execute programs that were originally written for Microsoft Windows. Wine also provides a software library known as Winelib which developers can compile Windows applications against in order to port them to Unix-like systems.
The name ‘Wine’ derives from the recursive acronym Wine Is Not an Emulator. While the name sometimes appears in the forms “WINE” and “wine”, the project developers have agreed to standardize on the form “Wine”.
The Wine developers released the first …
