AutoCAD 2000i Tutorial - Second Level: 3D ModelingDesign includes all activities involved from the original concept to the finished product. Design is the process by which products are created and modified. For many years designers sought ways to describe and analyze three-dimensional designs without building physical models. Although orthographic projections can be used to provide much of the information, they still require designers to translate between the three-dimensional object and flat two-dimensional views. With the advancements in computer technology, the creation of three-dimensional models on computers offers a wide range of benefits. Computer models are easier to interpret and can be altered easily. Computer models can be analyzed using finite element analysis software, and simulation of real-life loads can be applied to the computer models and the results graphically displayed.
There are three basic types of three-dimensional computer geometric modeling methods: wireframe modeling, surface modeling and solid modeling. The 3-D wireframe models contain information about the locations of all the points and edges in space coordinates. The 3-D models can be viewed from any direction as needed and are reasonably good representations of 3-D objects. But because surface definition is not part of a wireframe model, all wireframe images have the inherent problem of ambiguity.

Download PDFLockr: Social Access Control for Web 2.0Sharing personal content online is surprisingly hard despite the recent emergence of a huge number of content sharing systems and sites. These systems suffer from several drawbacks: they each have a different way of providing access control which cannot be used with other systems; moving to a new system is a lengthy process and requires registration and invitation of all one’s friends to the new system; and the rules for access control are complicated and become more so as our networks of online friends grow.
In this paper, we present Lockr–an access control scheme based on social relationships that makes sharing personal content easy. Lockr separates social networking information from the content sharing mechanisms, thereby eliminating the need for users to maintain many site-specific copies of their social networks. We describe Lockr’s design, security properties, and limitations. We also present how we integrated Lockr with two popular systems for sharing content online – BitTorrent and Flickr.
Today, sharing personal content is surprisingly difficult. Current systems suffer from a number of drawbacks. They are cumbersome to use, they impose artificial limits on the size of shared content (e.g., pictures and video), and they make it difficult to restrict content only to a specific set of users. For those Web sites that do provide access control, they typically require all the participants to be registered with the site in question. This imposes the burden that users must register with many sites, and maintain separate and potentially inconsistent copies of their social networks for eachCryptanalysis of Microsoft’s Point-to-Point Tunneling Protocol (PPTP)The Point-to-Point Tunneling Protocol (PPTP) is used to secure PPP connections over TCP/IP links. In this paper we analyze Microsoft’s Windows NT implementation of PPTP. We show how to break both the challenge/response authentication protocol (Microsoft CHAP) and the RC4 encryption protocol (MPPE), as well as how to attack the control channel in Microsoft’s implementation. These attacks do not necessarily break PPTP, but only Microsoft’s implementation of the protocol.
Many organizations and institutions are not centralized. Branch offices, virtual corporations, and traveling employees make the notion of running dedicated network connections to each location logistically impossible. The concept of virtual networking provides a solution to this problem by tunneling cojoined network space over other, transitory and insecure, networks (such as the Internet), thus enabling remote locations to appear to be local. This is done without the expense incurred from running leased lines or dedicated cabling to each location, and is sometimes called a “tunnel.”
While virtual networks solve the problem of de- centralized machines, they create a new problem. They open up traffic that was previously considered internal to the company, to any prying eyes on the networks it traverses. Authentication and encryption are required to keep this virtual network traffic not only tamperproof but private. The result, virtual networking connections combined with cryptographic protections, is a Virtual Private Network (VPN).
The security of a VPN is based on the security of its authentication and encryption protocols. If a VPN’s cryptography is weak, then its security is no better than a non-private virtualMicrosoft Compound Document File FormatThis document contains a description of the binary format of Microsoft Compound Document files. Compound document files are used to structure the contents of a document in the file. It is possible to divide the data into several streams, and to store these streams in different storages in the file. This way compound document files support a complete file system inside the file, the streams are like files in a real file system, and the storages are like sub directories.
Compound document files work similar to real file systems. They contain a number of independent data streams (like files in a file system) which are organised in a hierarchy of storages (like sub directories in a file system). Storages and streams are named. The names of all storages and streams that are direct members of a storage must be different. Names of streams or storages that are members of different storages may be equal. Each compound document file contains a root storage that is the direct or indirect parent of all other storages and streams.
Example of a storage/stream hierarchy. The names of all direct members of a storage must be different, but it is possible that two different storages contain a stream named “Stream1”.

Simply water under the bridge. 12,000 Windows Vista and Windows XP impacted customers and 20 hours of erroneous invalidations the past weekend’s WGA cracks is now complete with a Microsoft apology. The Redmond company revealed at the end of some three-four days worth of investigating that the WGA lapse was generated by a human error. Nothing more and nothing else than the preproduction code being accidentally (!) sent to production servers and managing to impact both Microsoft’s activation and validation aspect of the general anti-piracy mechanism.
Alex Kochis, Senior Product Manager for Windows Genuine Advantage revealed that the preproduction code was taken down in less than 30 minutes by rolling back all changes introduced, but that its effects ripped through the WGA validation process from August 24 to August 25 incorrectly labeling genuine copies of Vista and XP as pirated. “For the customers who failed validation from Friday afternoon through Saturday morning the experience was that features we refer to as ‘genuine-only’ features were disabled. These features are Windows Aero, Windows ReadyBoost, Windows Defender (in this state Defender will scan and identify all threats it would ordinarily, but will only clean ones marked ‘severe’) and Windows Update (in this state only ‘optional’ updates are unavailable, all others can still be downloaded, including security updates).

Cooling integrated circuit would double every 18 months. This has pretty much held true until now, and with so many traisto getting packed into such a small space, it's inevitable that more and more heat is produced. Cooling is a problem with PCs today, but it can be used to your advantage if you twist it in the right ways. Exceed the basic cooling requirements of your chip, and you can overclock it even further; with a liquid cooling system you should be able to overclock it to a ridiculous level. On the other end of the scale, if you're not interested in making your PC faster, you can certainly cut down on the amount of noise that your PC produces by fitting quieter alternative coole to your CPU and graphics card.
