Books by N B Venkateswarlu

In the recent years, many eye-catching books became available with titles tagged with FAQ (Frequently Asked Questions) such as C FAQ, C++ FAQ, Java FAQ etc. In the same pattern, this book is also designed as UNIX / LINUX FAQ .The author has vast experience in Unix and Linux and that prompted him to bring a book for the benefit of students to perfect their knowledge in these areas. The questions and answers are taken from various USENET groups in the Internet. Most of the questions are tested under Linux platforms, such as Red Hat, Fedora core or Slack ware distributions. The book is divided into four modules - 1. Questions and Answers, 2. Multiple Choices Questions (MCQs), 3. Fill in the blanks and 4. True or false statements. The questions, in each module, range from simple to complex.Features Most generally asked questions about Linux in Interviews explored in detail A module on filling the blanks includes almost 500 questions with answers About 500 multiple choice questions with answers are included to make the students ready for competitive exams and to test their abilities in UNIX/Linux about 700 true or false questions are included to test the technical knowledge of the candidates Some questions related to System Administration are also included Questions related to C and UNIX/Linux interface are covered

In the recent years, Linux, a public domain, freely available Unix variant has attracted the people very much. Today's complex production environments demands superior application performance. Linux is having extraordinary advantages such as : complete source code access, availability of exceptional optimization, testing tools. This book is to explore this facet of Linux.Features Explained Linux success stories with emphasis on facilities and tools available in Linux for SW development Explains gcc (GNU) toolchain in detail, combining C and C++, C and Java, and C and Fortran in a lucid manner How command line arguments can be handled by C/C++ programs with getopt, argp library are dealt Discusses about environment variables and their management System limits are explored with their implication of program performance Explains about how assembly programming can be done under Linux How to mix C and assembly, how system calls can be called from assembly, how modules can be developed in assembly and a bare boot (OS) program creation, are discussed in detail. How static and dynamic libraries are A popularly used tool for detecting memory errors, Electric Fence, is explained with concept oriented examples A chapter on Valgrind explained as to how memory can be checked for memory leaks, segment violations, analyze the cache performance in an illustrative manner Describes memory mapping of files, especially for large files and the impact on program's performance. Gnu debugger (gdb) is detailed; gcov and gprof explains about profiling of a C program to improve its performance; make, rcs, SW tools explains how they can be used for SW development in practice.with concept oriented examples with special reference to Web enabled applications. developed and commissioned in Linux is explained and how Libtool can be used for library development is discussed Dealt with Lex/Yacc tools, which are to be used in compiler development Memory management, memory errors, Linux memory management, etc., are described with illustrative examples

Since early 1970, Unix operating system has gone through many metamorphosis. As of now many variants of Unix systems are available and some of them are commercial whereas the others are freely available. As a result, many people are becoming Unix/Linux enthusiasts especially in India. Hundreds of books have been written in the past, which explores various facets of Unix. This book attempts to expose the reader to Linux Installations and Programming, and it is assumed that the reader has had some prior exposure to an operating system such as Windows, as well as C programming. The contents of the book have been presented by a team of ten faculty members to 100 teachers of engineering colleges in Tamil Nadu in a short course conducted in NRCFOSS in June 2005, and the book itself is largely an edited version of the same. It is meant to serve the purpose of an introductory level text book on this topic, for a typical one semester course in an undergraduate program of CSE/IT Explains elementary Linux/Unix commands in a lucid manner and emphasizes shell and awk programming which are vital for system administration. Describes step by step how Linux is to be installed, how partitions including swap partition can be made and how to configure network, proxy server and web server. Network installation along with SLIP, PPP connections are explained. How web servers, email servers, print servers can be made running on a machine is explained in detail. A separate chapter is included for those who are new to networks, to enable them to install the networks. A chapter on System Logging is included so that the system administrators can monitor the activities/ processes in their system. A Chapter on X windows explores the architecture of X windows system. How GUI is developed under Linux is explained with Qt and Gtk libraries, along with live examples Python language is explained with concept oriented examples with special reference to Web enabled applications
