Seminar on Linux Virtual File System

A virtual file system (VFS) or virtual filesystem switch is an abstraction layer on top of a more concrete file system. The purpose of a VFS is to allow client applications to access different types of concrete file systems in a uniform way. A VFS can, for example, be used to access local and network storage devices transparently without the client application noticing the difference. It can be used to bridge the differences in Windows, Mac OS and Unix filesystems, so that applications can access files on local file systems of those types without having to know what type of file system they are accessing.

A VFS specifies an interface (or a "contract") between the kernel and a concrete file system. Therefore, it is easy to add support for new file system types to the kernel simply by fulfilling the contract. The terms of the contract might change incompatibly from release to release, which would require that concrete file system support be recompiled, and possibly modified before recompilation, to allow it to work with a new release of the operating system; or the supplier of the operating system might make only backward-compatible changes to the contract, so that concrete file system support built for a given release of the operating system would work with future versions of the operating system.

Ebook Search Engine Optimization Starter Guide

Welcome to Google's Search Engine Optimization Starter Guide. This document first began as an
effort to help teams within Google, but we thought it'd be just as useful to webmasters that are new to
the topic of search engine optimization and wish to improve their sites' interaction with both users and
search engines. Although this guide won't tell you any secrets that'll automatically rank your site first
for queries in Google (sorry!), following the best practices outlined below will make it easier for search
engines to both crawl and index your content.

 

          

Search engine optimization is often about making small modifications to parts of your website. When
viewed individually, these changes might seem like incremental improvements, but when combined

with other optimizations, they could have a noticeable impact on your site's user experience and
performance in organic search results. You're likely already familiar with many of the topics in this
guide, because they're essential ingredients for any webpage, but you may not be making the most
out of them.

Even though this guide's title contains the words "search engine", we'd like to say that you should
base your optimization decisions first and foremost on what's best for the visitors of your site. They're
the main consumers of your content and are using search engines to find your work. Focusing too
hard on specific tweaks to gain ranking in the organic results of search engines may not deliver the
desired results. Search engine optimization is about putting your site's best foot forward when it
comes to visibility in search engines.

Ebook - Java™ Application Development on Linux

Why another book on Java? Why a book on Java and Linux? Isn’t Java a platform-independent system? Aren’t there enough books on Java? Can’t I learn everything I need to know from the Web?
No doubt, there are a host of Java books on the market. We didn’t wake up one morning and say, “You know what the world really needs? Another book about Java!” No. What we realized was that there are a couple of “holes” in the Java book market.
First, Linux as a development platform and deployment platform for Java applications has been largely ignored. This is despite the fact that the *nix platform (meaning all UNIX and UNIX-like systems, Linux included) has long been recognized as one of the most programmer-friendly platforms in existence.

                      
Those few resources for Java on Linux that exist emphasize tools to the exclusion of the Java language and APIs.
Second, books on the Java language and APIs have focused on pedagogical examples that serve to illustrate the details of the language and its libraries, but very few of these examples are in themselves practically useful, and they tend to deal only with the issues of writing programs, and not at all with deploying and maintaining them. Anyone who has worked on a major software project, especially a software project that is developed and deployed in a business for a business, knows that designing and coding are only about half of the work involved. Yes, writing Java code is only slightly affected by the development and the deployment platform, but the process of releasing and maintaining such applications is significantly different between platforms.

• You had some Basic or Pascal in school and you have a basic grasp of what programming is, but you’ve heard Java is easy to learn, really powerful, and very cool.

 

What if you know programming, but you don’t know object-oriented programming? Fear not. This book assumes no background in object-oriented design. If you know object-oriented programming, in fact, the first couple of days will be easy for you.

Ebook - JavaServer Pages, 2nd edition

Since its inception in 1999, Enterprise Java has taken the Java programming community by storm--developers have realized its potential for building distributed applications. Today, JavaServer Pages (JSP) continues to harmonize how web designers and programmers create dynamic web sites. JSP builds on the popular Java servlet technology and makes it easier to develop dynamic web applications--even if you're not a hard-core programmer.

 

JavaServer Pages, 2nd Edition is completely revised and updated to cover the substantial changes in the 1.2 version of the JSP specification, and also includes detailed coverage of the new JSP Standard Tag Library (JSTL)--an eagerly anticipated specification of a set of JSP elements for the tasks needed in most JSP applications. This book starts off by illustrating how JSP capitalizes on the power of Java servlets to create effective, portable web applications. It shows how to get started using the Apache Tomcat server, and provides detailed coverage of JSP syntax and features, error handling and debugging, authentication and personalization, and how to use JSTL for database access, XML processing, and internationalization.

JavaServer Pages recognizes the different needs of the two groups of professionals who want to learn JSP: page authors interested in using JSP elements in web pages, and programmers concerned with learning the JSP API and using JSP effectively in an enterprise application. If you're in the latter group, this book also teaches you such advanced topics as integrating servlets and JavaBeans with JSP, using the popular Apache Struts MVC framework to illustrate how it's done. Finally, the author presents how to develop custom tag libraries, using realistic examples that you can use as a springboard for your own JSP libraries.
