A Small Matter of Programming asks why it has been so difficult for end users to command programming power and explores the problems of end-user-driven application development that must be solved to afford end users greater computational power. Drawing on empirical research on existing end user systems, the book analyzes cognitive, social, and technical issues of end user programming. In particular, it examines the importance of task-specific programming languages, visual application frameworks, and collaborative work practices for end user computing with the goal of helping the designers and programmers understand and better satisfy the needs of end users who want the capability to create, customize, and extend their applications software. The ideas in the book are based on the author's research on two successful end user programming systems - spreadsheets and CAD systems - as well as other empirical research. Nardi concentrates on broad issues in end user programming, especially end users' strengths and problems, introducing tools and techniques as they are related to higher-level user issues.

Computer access control is an ongoing challenge. Left to themselves, computers tend to treat one user no differently than another. Computers use authentication to confidently associate an identity with a person. "Authentication: From Passwords to Public Keys gives readers a clear understanding of what an organization needs to reliably identify its users and how different techniques for verifying identity are executed. Authentication is one of the basic building blocks of security. To allow a computer system to distinguish between legitimate users and others, most sites give passwords to authorized users. Unfortunately, just as car thieves have found ways to defeat sophisticated locks and alarms, computer hackers are always finding new ways to circumvent password systems. The good news is that organizations now have available to them a broad range of alternatives to passwords, and a variety of ways to make passwords safer. A well-designed authentication system allows users to prove their identities conveniently and gain access to the network without threatening the safety of the organization. The first of its kind, "Authentication describes the entire range of authentication methods used today. It examines situations in which certain techniques fail and points out ways to strengthen them. Network professionals, designers, developers, administrators, planners, and managers will find in these pages the authentication strategy to protect their valuable systems. Through diagrams and examples, the author thoroughly explains the technical concepts behind authentication, focusing on existing, off-the-shelf solutions to security problems. "Authentication highlights real products andsolutions. If you are a network professional searching for the how and why of computer authentication, this is the book that will help you prevent unauthorized access on your network.

IHMC CmapTools (computer program) - The CmapTools program empowers users to construct, navigate, share and criticize knowledge models represented as concept maps. It allows users to, among many other features, construct their Cmaps in their personal computer, share them on servers (CmapServers) anywhere on the Internet, link their Cmaps to other Cmaps on servers, automatically create web pages of their concept maps on servers, edit their maps synchronously (at the same time) with other users on the Internet, and search the web for information relevant to ...

Dancing pigs (computer security) - In computer security, dancing pigs or the dancing pigs problem refers to a statement on user attitudes to computer security: that users primarily desire features without considering security, and so security must be designed in without the computer having to ask a technically ignorant user quote is commonly attributed to either Edward Felten] or [[Bruce Schneier. Felten said in Securing Java (1999), chapter one, part seven a choice between dancing pigs and security, users will pick dancing pigs every time.

Human-computer interaction - Human-computer interaction (HCI) or, alternatively, computer-human interaction (symbolized as Î§ Ï‡ Chi, the 22nd letter of the Greek alphabet) is the study of interaction between people (users) and computers. It is an interdisciplinary subject, relating computer science with many other fields of study and research.

Real-time computer graphics - Real-time computer graphics is the subfield of computer graphics focused on producing and analyzing images in real time. The term is most often used in reference to interactive 3D computer graphics, typically using a GPU, with video games the most noticeable users.
