VB.NET for Beginners to Programming Workbook and Videos

This unique series features 23 lessons, each lesson containing a workbook chapter with questions, exercises, further readings and one or more videos that step an absolute beginner through learning the most fundamental Visual Basic.NET topic matter. If you have never programmed before and want to learn Visual Basic.NET, this is a great place to start.

Anatomy of The Curriculum

Each of the "First Time Programmers" series contains two workbooks, a Questions edition and an Answers edition, which is identical to the Questions edition but contains the answers to all the questions in blue text.

Each lesson has one or more parts, as follows:

Lesson Objectives - Easily identify what the goals of the lesson are.

Lesson Text- Typically a few pages explaining the concepts for the lesson. The readings are concise and focus on concepts and ideas that are appropriate for the level you are at. The lessons avoid introducing unused or comple

Videos to Watch- Most lessons contain a video that demonstrates the concepts of the lesson. This is a powerful way to learn because its like watching over the shoulder of an expert while he "shows you the ropes."

Source Code - All source code that is created in the video is available for you to inspect on your own.

Extended Readings - These are links to parts of the Microsoft Developer's Network that are important for you to know. These readings extend the Lesson Text and often get into much more detail.

Definitions- While you are reading through the Lesson Text and the Extended Readings, you will come across many new terms that you should make sure you know.

Lesson Questions - Each lesson will have a number of review questions that re-inforce your new-found knowledge and force you to put it into your own words.

Best Practices - Most of the videos make recommendations that are considered "Best Practices" -- approaches that are tried and true. When available the workbook contains an area to record these Best Practices.

Exercises- Most lessons have a project for you to work on that covers concepts introduced in the readings and the video. The exercise requires you to open Visual Studio.NET and get your hands dirty. If you get stuck, you can watch a video that shows how we would have solved that exercise, including the source code.

Integrating Linux and Windows

From the Inside Flap
Introduction

In early 1998, I was looking at re-installing Windows 95 for the third time. Granted, I stress computers more than the average user, but this was getting old. I had been playing around with Linux since early 1995 and it looked like a good time to use it as my primary desktop.
I already knew how to install and configure Linux, but I had never used it as a desktop. I found plenty of books on Linux configuration, a few on using it as a server, but nothing on using it as a desktop. Instead I had to scour the Internet for useful information. What I have tried to do for this book is compile what I have learned over the past two years. Hopefully, this will save you the time and frustration of finding it yourselves.

So, how does Linux compare to Windows? As with anything else, each one has its own strengths and weaknesses.

Windows is king of the desktop for good reason. It has a polished interface and more end-user applications than any other operating system. It is also pre-installed on most new PCs, making it an easy, safe choice for most PCs. These factors combine to give Windows about 90% of the desktop market.

Linux is based on UNIX and inherits its security and stability from it. Linux is the most popular choice for public Web servers and it also holds about 25% of the small server market. It is also free (or nearly so) and comes packed with lots of useful tools for programming and server management.

These distinctions aren’t permanent, however. Several groups are working on polishing Linux’s interface. There is also a rush to develop more end-user applications for Linux. Large PC makers such as Dell, Compaq, and IBM are starting to offer Linux pre-installed on PCs.

While the market for Linux is comparatively small, Linux grew from less than 1% of the desktop market in 1998 to about 4% in 1999. This is amazing considering the Apple Macintosh, which has been around for 15 years, is holding at 5% of the desktop market.

Windows is also working to gain a foothold in the traditional strengths of the UNIX (and Linux) market: security, stability, and scalability. Microsoft put billions of dollars into the recently released Windows 2000 to address these issues. While the jury is still out on whether it succeeded, early reports say that Windows 2000 is much improved over earlier versions of Windows in these areas.

There are also many other reasons for choosing an operating system. They can often draw fanatical devotion (just ask a dedicated MacIntosh user). Despite (or maybe because of) its success, Microsoft has some very dedicated enemies. Just search the Internet for “Satan” or “Antichrist” and you will be surprised how many anti-Microsoft sites you hit. The Microsoft Antitrust case was also pushed forward by some dedicated foes. Some users try Linux as an alternative to Windows. It may not be the best way to choose an operating system, but never discount the power of fanatical devotion.

Such devotion is not necessary. Linux and Windows can peacefully coexist on the same computer. It is even possible to run Linux and Windows at the same time! The whole first section of this book is devoted to making coexistence as easy as possible.

The middle section is dedicated to finding useful applications for your Linux systems. Sometimes the same application is available for both Linux and Windows; in other cases, equivalent applications are available; and in a few cases, the applications are only available for Windows. The good news is that most people can do everything they need to do with either Linux or Windows.

The last section deals with networking. This is a rather advanced topic, but networking is moving from the Fortune 500 into homes and small businesses at a rapid rate. Networking is getting inexpensive enough to offer the same advantages that large businesses have long enjoyed: sharing files, printers, and Internet connections. The increasing use of high-speed Internet connections in the home will continue to drive up demand for home networking.

Fortunately, both Linux and Windows have programs that allow easy connection to each other. Samba allows Linux to act as a Windows file server. Additionally, the NFS and LPD programs allow Windows to use Linux’s native protocols.

So which is better, Linux or Windows? That is like asking whether a car or truck is better. They are built for different purposes. Windows plays the traditional role of the car; it is more polished and aimed at the mass market. Linux plays the traditional role of a truck; it is durable and intended to be used as a work vehicle. But like cars and trucks, the roles are starting to overlap. Linux is becoming more polished and easier to use and Windows is concentrating more on security and stability. Windows is still the choice for most users’ desktops, but it is no longer the only choice. As you will see in this book, Linux is a solid choice for a server and a viable alternative in the desktop market.

ASP.NET 3.5 Social Networking

ASP.NET 3.5 Social Networking
Packt Publishing | December 11, 2008 | ISBN: 1847194788 | 580 pages | PDF | 7 Mb

Social Networking is all about developing connections or ties between friends and associates. While people have always networked with one another the Internet has allowed us to network with people all over the world easily. Any interest or cause can support its own social network, where fans and followers can meet, chat, and share their views. But building a social networking site from scratch involves some complex logic, and some serious coding.

This book shows how to build a scalable, enterprise-ready social network using ASP.NET. The book uses the latest features of ASP.NET to provide a platform that is efficient, easy to maintain, and extensible. Whether you want to build your own social network, are developing a social site for a customer or employer, or just want a practical guide to developing complex ASP.NET applications then this book is ideal for you.

The book starts by planning the essential features of our social network, and then building a 'community framework' that will give our site a solid foundation and enable us to add all our social networking features. We then go on to create user accounts, profile pages, messaging systems, 'friend' relationships between members, media galleries, blogs, message boards, groups, and more. Along the way you will see LINQ, MVC, AJAX, and other features of ASP.NET 3.5 put to practical and interesting uses.

Network Troubleshooting Tools

Book description
Network Troubleshooting Tools helps you sort through the thousands of tools that have been developed for debugging TCP/IP networks and choose the ones that are best for your needs. It also shows you how to approach network troubleshooting using these tools, how to document your network so you know how it behaves under normal conditions, and how to think about problems when they arise so you can solve them more effectively.
Over the years, thousands of tools have been developed for debugging TCP/IP networks. They range from very specialized tools that do one particular task, to generalized suites that do just about everything except replace bad Ethernet cables. Even better, many of them are absolutely free. There's only one problem: who has time to track them all down, sort through them for the best ones for a particular purpose, or figure out how to use them? Network Troubleshooting Tools does the work for you–by describing the best of the freely available tools for debugging and troubleshooting. You can start with a lesser-known version of ping that diagnoses connectivity problems, or take on a much more comprehensive program like MRTG for graphing traffic through network interfaces. There's tkined for mapping and automatically monitoring networks, and Ethereal for capturing packets and debugging low-level problems. This book isn't just about the tools available for troubleshooting common network problems. It also outlines a systematic approach to network troubleshooting: how to document your network so you know how it behaves under normal conditions, and how to think about problems when they arise, so you can solve them more effectively. The topics covered in this book include:
* Understanding your network
* Connectivity testing
* Evaluating the path between two network nodes
* Tools for capturing packets
* Tools for network discovery and mapping
* Tools for working with SNMP
* Performance monitoring
* Testing application layer protocols
* Software sources
If you're involved with network operations, this book will save you time, money, and needless experimentation.
