24 Bit 96 Khz Digital Audio Workstation Using High Performance Be Operating System on a Multiprocessor Intel Machine
24 bit 96 kHz Digital Audio Workstation using high performance Be Operating System on a multiprocessor Intel machine by: Michal Jurewicz - Mytek, Inc., New York, NY, USA Timothy Self - Be, Inc., Menlo Park, CA, USA ABSTRACT Digital Audio Workstation (DAW) has quickly established itself as the most important digital audio production tool. With the advent of high-resolution multi-channel audio formats and Internet audio exchange, the high performance and flawless operations of the desktop DAW have become a necessity. The authors explaining why current popular computer architectures are not suited to these new tasks, explore the possibilities of the new Be Operating System (BeOS)- specifically designed and optimized to handle digital audio and video. New features, unattainable with current operating systems, are discussed. 1. Introduction Ever increasing performance of computers has caused a gradual migration of the key audio production tools from hardware embodiments to the virtual world of computers. This trend will continue, propelled by bottom line economics and the appearance of new features such as network audio exchange. Although current computer hardware is up to the task, existing general purpose operating systems are the actual performance bottleneck . Designed over 10 years ago for general purpose computing, they fail to meet increasing demands for speed and file size. The new BeOS has been designed from ground up to handle high bandwidth digital audio and video in a modern multiprocessing and multitasking environment. The paper focuses solely on the use of commodity personal computers (IBM Compatibles and Apple) and their operating systems (Windows, MacOS, BeOS and Linux). Although number of specialized platforms such as SGI provides superior performance, they were omitted, as their presence in the current professional audio environment is minimal. -

Fermi 5, 50125 Firenze, Italy Received 31 July 2006 / Accepted 26 September 2006 ABSTRACT Aims. We describe the mid- (MIR) and far- (FIR) infrared properties of a large (∼1000) sample of the most isolated galaxies in the local Universe. This sample is intended as a “nurture-free” zero point against which more environmentally influenced samples can be compared. Methods. We reprocess IRAS MIR/FIR survey data using the ADDSCAN/SCANPI utility for 1030 out of 1050 galaxies from the Catalogue of Isolated Galaxies (CIG) as part of the AMIGA project. We focus on diagnostics (FIR luminosity LFIR, R = log(LFIR/LB), and IRAS colours) thought to be sensitive to effects of environment or interaction. -

Sparta Dos X Review
Sparta Dos X Review# The SpartaDOS X cartridge a review by Doug Wokoun (copied from Usenet) The SpartaDOS X cartridge is the latest incantation of SpartaDOS for the 8-bit Atari and very possibly the most powerful Disk Operating System available for any 8-bit computer. The SpartaDOS X cartridge consists of 64K of ROM, with 48K (or 6 cartridge banks) formatted into a ROM-disk, and the remaining 16K used as the main DOS core. The ROM-disk contains files and drivers used by the system and SpartaDOS X versions of several utilities found in the SpartaDOS ToolKit. It also contains a very versatile ARC utility package. Some of the new features of SpartaDOS X (referred to as SDX): • built in, memory resident FORMAT utility. Old versions of SpartaDOS could only initialize Atari format disks using 'AINIT'. To initialize a SpartaDOS disk required the loading of a program called 'XINIT'. Now, any time an XIO #254 call is made, the SDX format menu is brought up. With this, you can select a variety of disk densities and types. It will also allow "1-second" formatting by simply rewriting the root directory on a formatted disk. • High speed disk I/O with U.S. Doubler, Atari XF551, and Indus GT disk drives. • New file loader supporting relocatable files (certain disk based commands can be held in memory and later removed) and symbol linking. • Probably the lowest MEMLO of any DOS. The DOS can load drivers under OS-RAM, into extended memory on an XE or at MEMLO on an 800. -

Dualbooting Amigaos 4 and Amigaos 3.5/3.9
Dualbooting AmigaOS 4 and AmigaOS 3.5/3.9 By Christoph Gutjahr. Licensed under the GNU Free Documentation License This tutorial explains how to turn a classic Amiga into a dualboot system that lets you choose the desired operating system - AmigaOS 4 or AmigaOS 3.5/3.9 - at every cold start. A "cold start" happens when... 1. the computer has just been switched on 2. you press the key combination Control-Amiga-Amiga for more than ten seconds while running AmigaOS 3 3. you press Control-Alt-Alt (instead of Control-Amiga-Amiga) under AmigaOS 4 During a "warm reboot" (e.g. by shortly pressing Control-Amiga-Amiga), the operating system that is currently used will be booted again. Requirements This tutorial is only useful for people using AmigaOS 3.5 or 3.9 in addition to AmigaOS 4. If you're using an older version of OS 3, you can not use the scripts described below. The Amiga in question should have two boot partitions - one for AmigaOS 4 and one for AmigaOS 3.5/3.9, both should be below the famous 4 GB barrier. The OS 4 partition must have a higher boot priority. Two different solutions There are two different approaches for dualbooting: the first one described below will display a simple 'boot menu' at every cold boot, asking the user to select the OS he wants to boot. The other solution explained afterwards will always boot into AmigaOS 4, unless the user enters the "Early Startup Menu" and selects the OS 3 partition as the boot drive. -
