What Does Software Engineering Involve?

The first point that has to be made about software engineering has to do with its scope of activities. Software engineering is the management of the entire process of development of computer systems to solve problems.

Dynamically Finding Live Program Invariants to Optimise Support Program Evolution

Explicitly stated program invariants can help programmers by identifying program properties that must be preserved when modifying code. In practice, however, these invariants are usually implicit. An alternative to expecting programmers to fully annotate code with invariants is to automatically infer likely invariants from the program itself. This research focuses on dynamic techniques for discovering invariants from execution traces. This article reports three results. First, it describes techniques for dynamically discovering invariants, along with an implementation, named Daikon, that embodies these techniques. Second, it reports on the application of Daikon to two sets of target programs. In programs from Gries's work on program derivation, the system rediscovered predefined invariants. In a C program lacking explicit invariants, the system discovered invariants that assisted a software evolution task. These experiments demonstrate that, at least for small programs, invariant inference is both accurate and useful. Third, it analyzes scalability issues, such as invariant detection runtime and accuracy, as functions of test suites and program points instrumented.

Virtual Laser Keyboard

Watching CSI the other night, I was amazed this gadget shown, and my first thought was NO WAY and my next one was how can it work.

Introduction to Software Development

Software development is a series of processes systematically undertaken to improve a business through the use of computerized information system. Software development has two major components, Systems Analysis and Design. Analysis specifies ‘what’ the system should do, that is it sets the objective and Design stated ‘how’ to accomplish this objective.

Requirement Analysis - Fact Finding Techniques

The first activity in analysis phase is to do the preliminary investigation. During the preliminary investigation data collecting is a very important and for this we can use the fact finding techniques.
