Progress DataXtend™ CE for C# pdfPerformance, availability, and scalability concerns often take a back seat to application functionality until the end of a development project. However, in Improving .NET Application Performance and Scalability, the authors warn: “Many, if not most, performance problems are introduced by specific architecture, design, and technology choices that you make very early in the development cycle, often in the design stage.” The strategies they recommend for building performance into an application stress the importance of choosing a scalable solution for persistent data access.
Analysts also confirm that data access technology has a significant impact throughout the project lifecycle:
– Development Phase: An R.B. Webber study concluded that coding and configuring data access typically accounts for 30 to 40% of total project effort.
– Tuning Phase: Performance and data integrity issues often do not surface until testing.
– Deployment Phase: According to a 2004 Forrester Research survey, 66% of performance problems are first identified by irate users calling the IT help desk.
Progress ® DataXtend™ CE for C# provides cost effective, scalable, and high performance object oriented access to relational data for Microsoft ® .NET applications. DataXtend CE meets and exceeds data access requirements at each stage of the project lifecycle, ensuring a fast, free flow of data. Tightly integrated features shorten development schedules, simplify performance tuning, and ensure enterprisewide deployment scalability and high availability.
In the previously referenced document, a Microsoft architect strongly suggests that development teams plan up front for performance: “If you’re very lucky, performance problems can be fixed after the fact.

Programs that fail to use appropriate bounds checking can allow an attacker to write data beyond the intended boundaries of a buffer and thus possibly corrupt control structures in the program. This enables an attacker to execute arbitrary code with the same privilege as the victim process. An attacker’s preference is usually to overwrite the saved instruction pointer that is pushed onto the stack before a function call or to overwrite a function pointer that will be used later in the program. It is also possible to use these attacks simply to overwrite other data.
This kind of attack is harder to prevent but, fortunately, is less common than the previous type and is not discussed here. Buffer overflows first gained attention with the release of the famed Morris worm which exploited a buffer overflow in fingerd [1]. Despite the attack used in the Morris worm, buffer overflows did not become popular until the release of two papers that detailed the discovery and exploitation of these vulnerabilities [2,3]. This paper discusses vulnerabilities in two compiler-level protection mechanisms, StackGuard and Point-Guard. While this paper takes a critical look at both of these solutions, it does not intend to make them seem insignificant. The attacks described in this paper help to show how StackGuard and PointGuard should be complemented to construct a more complete protection system.

By design, radial tire construction and low aspect ratios contribute to a vehicle’s ride and handling quality. Proper tire mounting, balancing and installation are critical to attaining a smooth vehicle ride. Vehicle vibration and a suspected problem tire may actually be due to an improperly balanced tire and wheel assembly or related to the mechanical condition of the vehicle. BALANCING The technical definition of balance is the uniform distribution of mass about an axis of rotation, where the center of gravity is in the same location as the center of rotation.
A balanced tire is one where mass of the tire – when mounted on its wheel and the car’s axle – is uniformly distributed around the axle (its center of rotation). Balanced tires can spell the difference between a positive and negative driving experience. Drivers of new, high performance or luxury vehicles may be more sensitive to imbalance problems, but no driver is happy with an annoying vibration. An out-of-balance tire and wheel assembly:
• Degrades ride quality and driver comfort.
• Shortens the life of tires, bearings, shock absorber, and other suspension components. Vibration is the most noticeable effect of imbalance.
• It is dependent on vehicle speed and may be felt in the steering wheel, seats or floor board.
• It often first becomes apparent between 40 and 45 mph and changes in magnitude with greater speeds.

Download pdf USB to RS485 Converter Card User Manual for Windows VistaResolving Tag AmbiguityTagging is an important way for users to succinctly describe the content they upload to the Internet. However, most tag-suggestion systems recommend words that are highly correlated with the existing tag set, and thus add little information to a user’s contribution. This paper describes a means to determine the ambiguity of a set of (user-contributed) tags and suggests new tags that disambiguate the original tags. We introduce a probabilistic framework that allows us to find two tags that appear in different contexts but are both likely to co-occur with the original tag set. If such tags can be found, the current description is considered “ambiguous” and the two tags are recommended to the user for further clarification. In contrast to previous work, we only query the user when information is most needed and good suggestions are available. We verify the efficacy of our approach using geographical, temporal and semantic metadata, and a user study. We built our system using statistics from a large (100M) database of images and their tags.
Tags are an important part of today’s multimedia databases. They are often contributed by users when they submit an image or video and form a key part of the search experience. Content-based multimedia search remains out of reach, and a simple tag like “Tokyo” provides more information than we can possibly glean from content-based algorithms. Thus, making it as easy as possible for users to enter tags alongside multimedia content is important. This work addresses the problem of eliciting high-quality tags
