How best to create high quality software is a separate and controversial problem covering software design principles, so-called "best practices" for writing code, as well as broader management issues such as optimal team size, process, how best to deliver software on time and as quickly as possible, work-place "culture", hiring practices, and ...
These accidents highlighted the dangers of software control of safety-critical systems. The Therac-25 has become a standard case study in health informatics, software engineering, and computer ethics. It highlights the dangers of engineer overconfidence [2]: 428 after the engineers dismissed end-user reports, leading to severe consequences.
The first flight of the Ariane V rocket self-destructed due to an overflow occurring during a floating-point to integer conversion in the on-board guidance software. The same software had been used successfully in the Ariane IV program, but the Ariane V produced larger values for some variable, causing the overflow. [31] [32]
Software engineering is a field within computer science and a branch of engineering focused on designing, developing, testing, and maintaining of software applications. It involves applying engineering principles and computer programming expertise to develop software systems that meet user needs.
The term "software engineering" was deliberately chosen as the conference title to provoke thought regarding the need for disciplined approaches in software development. [ 4 ] During the conference, participants discussed issues such as software reliability, project management, and the challenges of large-scale software systems. [ 1 ]
A software bug is a design defect in computer software. A computer program with many or serious bugs may be described as buggy . The effects of a software bug range from minor (such as a misspelled word in the user interface ) to severe (such as frequent crashing ).
In software engineering, the laws of software evolution refer to a series of laws that Lehman and Belady formulated starting in 1974 with respect to software evolution. [1] [2] The laws describe a balance between forces driving new developments on one hand, and forces that slow down progress on the other hand. Over the past decades the laws ...
The first modern theory of software was proposed by Alan Turing in his 1935 essay Computable numbers with an application to the Entscheidungsproblem (decision problem). [4] This eventually led to the creation of the twin academic fields of computer science and software engineering, which both study software and its creation. Computer science is ...
