In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of systems, you need to delve deep into the heart of the kernel. The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in what order. It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn't kept waiting any longer than necessary for the relatively slow disks.The third edition of "Understanding the Linux Kernel" takes you on a guided tour of the most significant data structures, algorithms, and programming tricks used in the kernel. Probing beyond superficial features, the authors offer valuable insights to people who want to know how things really work inside their machine. Important Intel-specific features are discussed. Relevant segments of code are dissected line by line. But the book covers more than just the functioning of the code; it explains the theoretical underpinnings of why Linux does things the way it does.
This edition of the book covers Version 2.6, which has seen significant changes to nearly every kernel subsystem, particularly in the areas of memory management and block devices. The book focuses on the following topics:
Memory management, including file buffering, process swapping, and Direct memory Access (DMA)
The Virtual Filesystem layer and the Second and Third Extended Filesystems
Process creation and scheduling
Signals, interrupts, and the essential interfaces to device drivers
Timing
Synchronization within the kernel
Interprocess Communication (IPC)
Program execution
"Understanding the Linux Kernel" will acquaint you with all the inner workings of Linux, but it's more than just an academic exercise. You'll learn what conditions bring out Linux's best performance, and you'll see how it meets the challenge of providing good system response during process scheduling, file access, and memory management in a wide variety of environments. This book will help you make the most of your Linux system.

Nagios: System and Network Monitoring shows how to configure and use Nagios, an open source system and network monitoring tool. Nagios makes it possible to continuously monitor network services (SMTP, POP3, HTTP, NNTP, PING, etc.), host resources (processor load, disk and memory usage, running processes, log files, etc.), and environmental factors (such as temperature). When Nagios detects a problem, it communicates the information to the sys admin via email, pager, SMS, or other user-defined method; current status information, historical logs, and reports can also be accessed via a web browser. Nagios System and Network Monitoring covers the Nagios core, all standard Nagios plug-ins and selected third-party plug-ins, and shows readers how to write their own plug-ins. The book covers Nagios 2.0 and is backwards compatible with earlier versions.

Assuming readers have a basic familiarity with C or C++, Frantisek Franek describes the techniques, methods and tools available to develop effective memory usage. The overwhelming majority of "bugs" and crashes in computer programming stem from problems of memory access, allocation, or deallocation. Such memory related errors are notoriously difficult to resolve. Moreover, the role that memory plays in C and C++ programming is a subject often overlooked in courses and in books. Most professional programmers learn about it entirely through actual experience of the problems it causes.

The last decade has seen tremendous growth in usage of the World Wide Web. Web caching is a technology aimed at reducing the transmission of redundant network traffic and improving access to the Web. The key idea in Web caching is to cache frequently- accessed content so that it may be used profitably later. This leads to cost savings, reduction in network traffic, improved access and better content availability. Web Caching and Its Applications gives the reader an understanding of the latest developments in Web caching research.
Topics covered include architectural aspects, aspects requiring coordination among caches, aspects related to network traffic, techniques that complement caching, practical aspects, and aspects related to performance. While Web Caching and Its Applications is designed for a professional audience, students will appreciate the exercises for applying the knowledge to solving practical problems related to Web caching and Internet performance. The book includes an exhaustive list of references for further study.

Value-Range Analysis of C Programs describes a static analysis for detecting buffer overflows. A buffer overflow in a C program occurs when input is read into a memory buffer whose length exceeds that of the buffer. Overflows usually lead to crashes and may even enable a malicious person to gain control over a computer system. They are recognised as one of the most widespread forms of computer vulnerability.
Based on the analysis of a standard mail-forwarding program, necessary refinements of the basic analysis are examined, thereby paving the way for an analysis that is precise enough to prove the absence of buffer overflows in legacy C code.

The phenomenal increases in processing power and memory capacity of computing hardware over recent years have allowed manufacturers to produce smaller and smaller computer systems such as palmtop PCs, smart cards and embedded control systems on domestic and industrial appliances. New techniques such as dynamic memory management and object-orientation help programming but tend to require additional memory. Standard programming techniques do not cope with these limited memory-capacity environments. This book will provide practical help for programmers developing software for this kind of environment. The major content is a series of patterns developed by the authors based on solutions which have been found to work in real-life situations. They range from small system design patterns and process management patterns, to patterns for User Interface development, compression and memory storage. This book will appeal to developers using Windows CE or building mobile telephones, smart cards, embedded devices, set-top computers - in short, all programmers working with memory-constrained systems.

Here is a book that explores the fascinating interconnections between three seemingly unrelated topics. The reader need have no specialist mathematical background to follow the text beyond high school mathematics, which makes it suitable for budding magicians and students of all ages. It is a fun book that looks at the mathematics of the perfect shuffle and develops the procedures for controlling dynamic memories and doing some clever card tricks. Each chapter begins with the description of a card trick and ends with its explanation, usually using some mathematics developed earlier. The book itself is designed as a prop for a trick, but you don't need to use mathematics or even understand it to do some 'magic'.

Systematic Methodology for Real-Time Cost-Effective Mapping of Dynamic Concurrent Task-Based Systems on Heterogeneous Platforms gives an overview of the state-of-the-art in system-level design trade-off explorations for concurrent tasks running on embedded heterogeneous multiple processors. The targeted application domain covers complex embedded real-time multi-media and communication applications.
Many of these applications are concurrent in the sense that multiple subsystems can be running simultaneously. Also, these applications are so dynamic at run-time that the designs based on the worst case execution times are inefficient in terms of resource allocation (e.g., energy budgets). A novel systematical approach is clearly necessary in the area of system-level design for the embedded systems where those concurrent and dynamic applications are mapped. This material is mainly based on research at IMEC and its international university network partners in this area in the period 1997-2006. In order to deal with the concurrent and dynamic behaviors in an energy-performance optimal way, we have adopted a hierarchical system model (i.e., the gray-box model) that can both exhibit the sufficient detail of the applications for design-time analysis and hide unnecessary detail for a low-overhead run-time management. We have also developed a well-balanced design-time/run-time combined task scheduling methodology to explore the trade-off space at design-time and efficiently handle the system adaptations at run-time. Moreover, we have identified the connection between task-level memory/communication management and task scheduling and illustrated how to perform the task-level memory/communication management in order to obtain the design constraints that enable the this connection. A fast approach is also shown to estimate at the system-level, the energy and performance characterization of applications executing on the target platform processors.

The wholesale capture and distribution of knowledge over the last thirty years has created an unprecedented need for organizations to manage their knowledge assets. Knowledge Management (KM) addresses this need by helping an organization to leverage its information resources and knowledge assets by "remembering" and applying its experience. KM involves the acquisition, storage, retrieval, application, generation, and review of the knowledge assets of an organization in a controlled way. Today, organizations are applying KM throughout their systems, from information management to marketing to human resources.
Applying Knowledge Management: Techniques for Building Corporate Memories examines why case-based reasoning (CBR) is so well suited for KM. CBR can be used to adapt solutions originally designed to solve problems in the past, to address new problems faced by the organization. This book clearly demonstrates how CBR can be successfully applied to KM problems by presenting several in-depth case-studies.
Ian Watson, a well-known researcher in case-based reasoning and author of the introductory book, Applying CBR: Techniques for Enterprise Systems has written this book specifically for IT managers and knowledge management system developers.
* Provides 7 real-world applications of knowledge management systems that use case-based reasoning techniques.
* Presents the technical information needed to implement a knowledge management system.
* Offers insights into the development of commercial KM CBR applications
* Includes information on CBR software vendors, CBR consultants and value added resellers
