Debugging is the process of finding and reducing the number of bugs in computer software and electronic hardware. When a program crashes, the debugger shows the position in the original code. A good debugger plays an essential role in software development. This article examines three different types of debuggers: source-level debuggers, memory debuggers and bug tracking software. To provide an insight into the quality of software that is available, we have compiled a list of 9 advanced Linux debugging tools. Hopefully, there will be something of interest here for anyone who wants to fix, and help fix, bugs.

An integrated development environment (IDE) (sometimes known as an integrated design environment or integrated debugging environment) is a software application that provides comprehensive facilities to programmers for software development.

Version control systems play an essential role for developers. First up, they allow developers to safely store successive versions of source code. Besides providing a secure backup of the source code, this type of software lets developers revert back to a stable release if subsequent code changes have unforeseen consequences.

Computer-aided design (CAD) is the use of computer technology for the design of objects, real or virtual. ?It often refers to the drafting (technical drawing and engineering drawing) of a part or product, including entire buildings. However, CAD software is used in a wide variety of other fields such as electronics and woven fabrics.

Remote Desktop Control displays the screen of another computer (via Internet or local area network) on a local screen. This type of software enables users to use the mouse and keyboard to control the other computer remotely.

BitTorrent is an open source peer-to-peer file protocol for sharing large software and media files. It is a well established protocol which accounts for a significant proportion of internet traffic.

Educational games are games designed to teach people, typically children, about a certain subject or help them learn a skill as they play. Sometimes this type of software is known as games edutainment because they combine education and entertainment.

A news aggregator is software which collect news, weblog posts, and other information from the web so that they can be read in a single location for easy viewing. With the range of news sources available on the internet, news aggregators play an essential role in helping users to quickly locate breaking news.

Voice over IP (VoIP) software enables telephone-like voice conversations across IP based networks. A VoIP phone service is often cheaper than a traditional Public Switched Telephone Network (PSTN) phone service and removes geographic restrictions to telephone numbers.

Microsoft Windows remains the dominant desktop operating system with approximately 90% of the client operating system market. If Microsoft's monopoly is ever going to be challenged by Linux, there has to be an easy way for Windows' users to be able to learn about this rival operating system. However, it would be naive to think that a Windows user is going to wipe their Windows partition, write off their years of Windows computing knowledge and install Linux just to see if it has more to offer.

Project management tools encompass many different types of software such as scheduling, resource allocation, collaboration software, quality management, and cost control / budget management. This type of software is typically used by project managers looking to plan and control resources, costs and schedules to meet the objectives of a project.

Individuals wanting to learn about the Linux operating system have a large selection of books to choose from. There are many thousands of informative Linux books which are in-print and available to download or buy at reasonable cost. However, as many users are attracted to Linux for the very reason that it is available under a freely distributable license, some will also want this to extend to the documentation they read.

The venerable DVD is a removable media format that was conceived over 15 years ago. However, it still remains today the ideal format for many uses, although blu-ray is starting to make significant inroads in the field of multimedia playback.

Instant messaging (IM) is a form of real-time communication between two or more individuals based on typed text. The text is conveyed via devices connected over a network such as the Internet. There are a number of different instant messaging protocols which are used by the major networks. The primary ones are XMPP (used by Google Talk, Jabber etc), AOL Instant Messenger (AIM), ICQ, Yahoo! Messenger, Windows Live Messenger (formerly called MSN Messenger), and the venerable Internet Relay Chat (IRC). The IM clients featured in this article either cater for as many different networks as possible, or focus on a small subset.

The vast majority of Linux users would never be satisfied without access to a graphical user interface. However, even in 2009 there remain many reasons why console based applications can be extremely desirable. Although console applications are very useful for updating, configuring, and repairing a system, their benefits are not only confined to system administration. Console based applications are light on system resources (very useful on low spec machines), can be faster and more efficient than their graphical counterparts, they do not stop working when X needs to be restarted, and are great for scripting purposes. So what can users do with the command-line? There is a wide range of console based software which performs the same or similar functions to their graphical equivalents, even in the field of multimedia.

Online shopping is the activity that consumers engage in when purchasing products or services over the internet. This activity has many distinct advantages over 'traditional shopping' for both consumers and the businesses.

Weblog software (also known as blog software or blogware) enables users to maintain an ongoing chronicle of information on a website. Typically, a blog is a frequently updated, personal website, with diary-type commentary, descriptions of events, and sometimes includes graphics and video as well as links to articles on other sites. However, blogs can also be used for business purposes.
