"Everyone will want this book because it provides a great mix of practical experience, historical perspective, and a depth of understanding that only comes from being intimately involved in the field. I ve already enjoyed and learned from reading this book, and surely you will too." -Sam Leffler

Linux was first released into an unsuspecting world in the summer of 1991. Initially the spare-time hobby of a Finnish computer scientist by the name of Linus Torvalds, Linux was at first accessible only in software source code form to those with enough expertise to build and install it. Early enthusiasts (most also developers themselves by necessity) exploited the growth of the Internet in the early 1990s as a means to build online communities and drive development forward. These communities helped to build the first Linux software distributions, containing all the software components needed to install and use a Linux system without requiring users to be technical experts.

The Red Hat Linux and Fedora distributions have become one of the major Linux distributions, bringing to the PC all the power and flexibility of a Unix workstation as well as a complete set of Internet applications and a fully functional desktop interface. This book is designed not only to be a complete reference on Linux, but also to provide clear and detailed explanations of Linux features. No prior knowledge of Unix is assumed Linux is an operating system anyone can use

利用java实现文件的AES加密功能 This Java AES Crypt package contains the Java class es.vocali.util.AESCrypt, which provides file encryption and decryption using aescrypt file format. Requirements The Java AES Crypt package only works in Java 6, but can be easily adapted to Java 5 by replacing the call to NetworkInterface.getHardwareAddress() with something else. In order to use 256 bit AES keys, you must download and install "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files" from http://java.sun.com/javase/downloads/index.jsp

It can be argued that the current free-software movement is the most important thing happening in computing today. We are in the midst of a major shift from all software being proprietary and closely held by individual companies to a large body of software that can be freely acquired and used by anyone for any purpose. Free software now includes not only programming language compilers and linkers, but numerous utilities, graphical user interface environments, and even entire operating systems.

This sample is a simple example on how to perform a glow effect by rendering into an arbitrary size Frame Buffer Object (FBO). The Glow effect is performed on a specific part of the screen and can be done only on specific objects of the scene. You can imagine using such a postprocessing effect in CAD/DCC to emphasize some items from a selection or picking for example.

SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines. The library is written in C and is callable from either C or Fortran. The library routines will perform an LU decomposition with partial pivoting and triangular system solves through forward and back substitution. The LU factorization routines can handle non-square matrices but the triangular solves are performed only for square matrices. The matrix columns may be preordered (before factorization) either through library or user supplied routines. This preordering for sparsity is completely separate from the factorization. Working precision iterative refinement subroutines are provided for improved backward stability. Routines are also provided to equilibrate the system, estimate the condition number, calculate the relative backward error, and estimate error bounds for the refined solutions.

cordic methods describe essentially the same algorithm that with suitably chosen inputs can be used to calculate a whole range of scientific functions including sin, cos, tan, arctan, arcsin, arccos, sinh, cosh, tanh, arctanh, log, exp, square root and even multiply and divide. the method dates back to volder [1959], and due to its versatility and compactness, it made possible the microcoding of the hp35 pocket scientific calculator in 1972. here is some code to illustrate the techniques. ive split the methods into three parts linear, circular and hyperbolic. in the hp35 microcode these would be unified into one function (for space reasons). because the linear mode can perform multiply and divide, you only need add/subtract and shift to complete the implementation. you can select in the code whether to do the multiples and divides also by cordic means. other multiplies and divides are all powers of 2 (these dont count). to eliminate these too, would involve ieee hackery.
