    The Linux kernel is one of the most interesting yet least understood open-source projects. It is also a basis for developing new kernel code. That is why Sams is excited to bring you the latest Linux kernel development information from a Novell insider in the second edition of Linux Kernel Development. This authoritative, practical guide will help you better understand the Linux kernel through updated coverage of all the major subsystems, new features associated with Linux 2.6 kernel and insider information on not-yet-released developments. You ll be able to take an in-depth look at Linux kernel from both a theoretical and an applied perspective as you cover a wide range of topics, including algorithms, system call interface, paging strategies and kernel synchronization. Get the top information right from the source in Linux Kernel Development.

  • THIS is really two books in one: a tutorial and a reference manual for JDBC, the application program

    THIS is really two books in one: a tutorial and a reference manual for JDBC, the application programming interface that makes it possible for programmers to access databases from Java. The goal is to be useful to a wide range of readers, from database novices to database experts. Therefore, we have arranged the book so that information needed only by experts is separated out from the basic material. We hope that driver developers as well as application programmers and MIS administrators will find what they need. Because different sections are aimed at different audiences, we expect that few people will read every page. We have sometimes duplicated explanations in an effort to make reading easier for those who do not read all sections. This book will be most helpful to those who have some knowledge of the Java programming language and SQL (Structured Query Language), but one doesn t need to be an expert in either to understand the basic concepts presented here.

  • The LM158 series consists of two independent, high gain, internally frequency compensated operatio

    The LM158 series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.

  • The Staged Event-Driven Architecture (SEDA) is a new design for building scalable Internet services.

    The Staged Event-Driven Architecture (SEDA) is a new design for building scalable Internet services. SEDA has three major goals: To support massive concurrency, on the order of tens of thousands of clients per node To exhibit robust performance under wide variations in load and, To simplify the design of complex Internet services. SEDA decomposes a complex, event-driven application into a set of stages connected by queues. This design avoids the high overhead associated with thread-based concurrency models, and decouples event and thread scheduling from application logic. SEDA enables services to be well-conditioned to load, preventing resources from being overcommitted when demand exceeds service capacity. Decomposing services into a set of stages also enables modularity and code reuse, as well as the development of debugging tools for complex event-driven applications.

  • SCSI-2也称为Fast-SCSI

    SCSI-2也称为Fast-SCSI,传输速率为10MB/s。 后采用扩展总线宽度来增加数据流量的方式,提高整 体传输速率,于是SCSI-2规定了16位、32位数据总 线,使传输速率进一步提高为20MB/S,也就是Wide -SCSI,或是称作Fast SCSI-2。 Wide-SCSI采用4 位定址,使可连接的设备达到了15个。在接口电缆上, 为兼容SCSI-l所使用的A电缆,SCSI-2标准在A 电缆的基础上增加一条68pin的扁平电缆,称为B电 缆。目前还有不少SCSI的CD-ROM、CD-R、CD- RW还是使用SCSI-2界面。

    The goal of this library is to make ODBC recordsets look just like an STL container. As a user, you can move through our containers using standard STL iterators and if you insert(), erase() or replace() records in our containers changes can be automatically committed to the database for you. The library s compliance with the STL iterator and container standards means you can plug our abstractions into a wide variety of STL algorithms for data storage, searching and manipulation. In addition, the C++ reflection mechanism used by our library to bind to database tables allows us to add generic indexing and lookup properties to our containers with no special code required from the end-user. Because our code takes full advantage of the template mechanism, it adds minimal overhead compared with using raw ODBC calls to access a database.

  • This paper introduces an affine invariant of trapezia, and the explicit constraint equation between

    This paper introduces an affine invariant of trapezia, and the explicit constraint equation between the intrinsic matrix of a camera and the similarity invariants of a trapezium are established using the affine invariant. By this constraint, the inner parameters, motion parameters of the cameras and the similarity invariants of trapezia can be linearly determined using some prior knowledge on the cameras or the trapezia. The proposed algorithms have wide applicability since parallel lines are not rare in many scenes. Experimental results validate the proposed approaches. This work presents a unifying framework based on the parallelism constraint, and the previous methods based on the parallelograms or the parallelepipeds can be integrated into this framework. Key words: invariant parallelism constraint camera calibration 3D reconstruction
