Release Notes for X11R6.8.2 the X.Orgfoundation the Xfree86 Project, Inc
Release Notes for X11R6.8.2 The X.OrgFoundation The XFree86 Project, Inc. 9February 2005 Abstract These release notes contains information about features and their status in the X.Org Foundation X11R6.8.2 release. It is based on the XFree86 4.4RC2 RELNOTES docu- ment published by The XFree86™ Project, Inc. Thereare significant updates and dif- ferences in the X.Orgrelease as noted below. 1. Introduction to the X11R6.8.2 Release The release numbering is based on the original MIT X numbering system. X11refers to the ver- sion of the network protocol that the X Window system is based on: Version 11was first released in 1988 and has been stable for 15 years, with only upwardcompatible additions to the coreX protocol, a recordofstability envied in computing. Formal releases of X started with X version 9 from MIT;the first commercial X products werebased on X version 10. The MIT X Consortium and its successors, the X Consortium, the Open Group X Project Team, and the X.OrgGroup released versions X11R3 through X11R6.6, beforethe founding of the X.OrgFoundation. Therewill be futuremaintenance releases in the X11R6.8.x series. However,efforts arewell underway to split the X distribution into its modular components to allow for easier maintenance and independent updates. We expect a transitional period while both X11R6.8 releases arebeing fielded and the modular release completed and deployed while both will be available as different consumers of X technology have different constraints on deployment. Wehave not yet decided how the modular X releases will be numbered. We encourage you to submit bug fixes and enhancements to bugzilla.freedesktop.orgusing the xorgproduct, and discussions on this server take place on <[email protected]>. -
History of Rocket Technology
CHAPTER 1 History of Rockets 1. 1. INTRODUCTION Action-Reaction Principle Take any technology and you always find that its practical demonstration had been realized much before the theory was established. However, you may note that the fast and effective refinement of a technology begins only after its theory, explaining the underlying basic principles, has been established. The action-reaction principle that is fundamental to jet propulsion, which includes airbreathing- as well as rocket-propulsion, was theoretically explained only in 1687 by the English scientist Sir Isaac Newton by his famous publication “Philosophiae Naturalis Principia Mathematica (“Mathematical Principles of Natural Philosophy”). But, approximately 2100 years before this, Archytas, a Greek philosopher, mathematician, astronomer, statesman, and strategist, had demonstrated the action-reaction principle by his toy pigeon in the city of Tarentum, Fig. 1. 1. Archytas suspended on a wire his wooden pigeon that contained hot steam at an elevated pressure in its belly cavity. The other end of the wire was hooked on to the top of a tall pole. On releasing a plug, a jet of steam escaped through a hole from the rear of the pigeon to produce a thrust that made the toy pigeon fly in circles around the pole. Thus Archytas mystified and amused the citizens of Tarentum by his flying toy- pigeon and demonstrated the fundamental principle of propulsion: “every force has an equal and opposite reaction”. The second recorded-demonstration of the action-reaction principle was in the first century B.C. Hero of Alexandria, a Greek mathematician 1 and scientist, constructed a device known as aeolipile. -

3Dnow! Technology in Microsoft Directx
AMD WHITE PAPER ™ 3DNow! Technology in Microsoft DirectX 6.0 Delivering Leading-Edge 3D Graphics Performance for the New Era of Realistic Computing ADVANCED MICRO DEVICES, INC. One AMD Place Sunnyvale, CA 94088 Contact: Dale Weisman Public Relations (512) 602-5820 Anne Camden Public Relations (512) 602-2120 Page 1 52588A May 28, 1998 AMD WHITE PAPER Overview This white paper explains how 3DNow!™ technology improves upon the mature x86 instruction set (now more than 20 years old) to provide PC users with a richer, 3D-enhanced computing experience. The benefits of 3DNow! technology can be achieved with minimal impact on existing and emerging x86 software thanks to the support of an industry standard: the DirectX application programming interface (API). This paper provides an overview of DirectX, a review of the graphics pipeline and how it is enhanced by 3DNow! technology, and a summary of how the 3DNow! instruction set is used in different software layers, as well as the impact of the new 3D instructions on each layer. Introduction: What is DirectX Technology? The DirectX API is a group of technologies designed by Microsoft to make Windows® based computers an ideal platform for running and displaying applications rich in multimedia elements, such as full-color graphics, video, 3D animation, and surround sound. Built directly into the Microsoft® Windows family of operating systems, DirectX is an integral part of the Windows 95/98 and Windows NT® 5.0 operating systems, as well as Internet Explorer 4.0. DirectX components may also be automatically installed on a PC by advanced multimedia games and applications written for the Windows 95 operating system. -

PEENEMUENDE, NATIONAL SOCIALISM, and the V-2 MISSILE, 1924-1945 Michael
ABSTRACT Title of Dissertation: ENGINEERING CONSENT: PEENEMUENDE, NATIONAL SOCIALISM, AND THE V-2 MISSILE, 1924-1945 Michael Brian Petersen, Doctor of Philosophy, 2005 Dissertation Directed By: Professor Jeffrey Herf Departmen t of History This dissertation is the story of the German scientists and engineers who developed, tested, and produced the V-2 missile, the world’s first liquid -fueled ballistic missile. It examines the social, political, and cultural roots of the prog ram in the Weimar Republic, the professional world of the Peenemünde missile base, and the results of the specialists’ decision to use concentration camp slave labor to produce the missile. Previous studies of this subject have been the domain of either of sensationalistic journalists or the unabashed admirers of the German missile pioneers. Only rarely have historians ventured into this area of inquiry, fruitfully examining the history of the German missile program from the top down while noting its admi nistrative battles and technical development. However, this work has been done at the expense of a detailed examination of the mid and lower -level employees who formed the backbone of the research and production effort. This work addresses that shortcomi ng by investigating the daily lives of these employees and the social, cultural, and political environment in which they existed. It focuses on the key questions of dedication, motivation, and criminality in the Nazi regime by asking “How did Nazi authori ties in charge of the missile program enlist the support of their employees in their effort?” “How did their work translate into political consent for the regime?” “How did these employees come to view slave labor as a viable option for completing their work?” This study is informed by traditions in European intellectual and social history while borrowing from different methods of sociology and anthropology. -

Space Resources : Social Concerns / Editors, Mary Fae Mckay, David S
Frontispiece Advanced Lunar Base In this panorama of an advanced lunar base, the main habitation modules in the background to the right are shown being covered by lunar soil for radiation protection. The modules on the far right are reactors in which lunar soil is being processed to provide oxygen. Each reactor is heated by a solar mirror. The vehicle near them is collecting liquid oxygen from the reactor complex and will transport it to the launch pad in the background, where a tanker is just lifting off. The mining pits are shown just behind the foreground figure on the left. The geologists in the foreground are looking for richer ores to mine.
